Section 725.112  Required Notices

 

a)         Receipt from a Foreign Source.  The owner or operator of a facility that has arranged to receive hazardous waste subject to Subpart H of 35 Ill. Adm. Code 722, from a foreign source must submit the following required notices:

 

1)         As required by 35 Ill. Adm. Code 722.184(b), for imports where the competent authority of the country of export does not require the foreign exporter to submit to it a notification proposing export and obtain consent from USEPA and the competent authorities for the countries of transit, the owner or operator of the facility, if acting as the importer, must provide notification of the proposed transboundary movement in English to USEPA using the allowable methods listed in 35 Ill. Adm. Code 722.184(b)(1) at least 60 days before the first shipment is expected to depart the country of export.  The notification may cover up to one year of shipments of wastes having similar physical and chemical characteristics; the same United Nations/USDOT identification number from the Hazardous Materials Table in 49 CFR 172.101, incorporated by reference in 35 Ill. Adm. Code 720.111; the same USEPA hazardous waste waste numbers; and the same applicable OECD waste codes from the lists in the OECD Guidance Manual, incorporated by reference in 35 Ill. Adm. Code 720.111; and being sent from the same foreign exporter.

 

2)         As required by 35 Ill. Adm. Code 722.184(d)(2)(O), a copy of the movement document bearing all required signatures within three working days after receipt of the shipment to the foreign exporter; to the competent authorities of the countries of export and transit that control the shipment as an export and transit shipment of hazardous waste respectively; and on or after the electronic import-export reporting compliance date, to EPA electronically using USEPA’s Waste Import Export Tracking System (WIETS).  The original of the signed movement document must be maintained at the facility for at least three years.  The owner or operator of a facility may satisfy this recordkeeping requirement by retaining electronically submitted documents in the facility's account on USEPA's WIETS, provided that copies are readily available for viewing and production if requested by any USEPA or Agency inspector.  No owner or operator of a facility may be held liable for the inability to produce the documents for inspection under this section if the owner or operator of a facility can demonstrate that the inability to produce the document is due exclusively to technical difficulty with USEPA's WIETS for which the owner or operator of a facility bears no responsibility.

 

3)         As required by 35 Ill. Adm. Code 722.184(f)(4), if the facility has physical control of the waste and it must be sent to an alternate facility or returned to the country of export, such owner or operator of the facility must inform USEPA, using the allowable methods listed in 35 Ill. Adm. Code 722.184(b)(1) of the need to return or arrange alternate management of the shipment.

 

4)         As required by 35 Ill. Adm. Code 722.184(g), such owner or operator must:

 

A)        Send copies of the signed and dated confirmation of recovery or disposal, as soon as possible, but no later than thirty days after completing recovery or disposal on the waste in the shipment and no later than one calendar year following receipt of the waste, to the foreign exporter, to the competent authority of the country of export that controls the shipment as an export of hazardous waste.  For shipments recycled or disposed of on or after the electronic import-export reporting compliance date, to USEPA electronically using USEPA's WIETS.

 

B)        If the facility performed any of recovery operations R12, R13, or RC16 or disposal operations D13 through D15 or DC17, promptly send copies of the confirmation of recovery or disposal that it receives from the final recovery or disposal facility within one year of shipment delivery to the final recovery or disposal facility that performed one of recovery operations R1 through R11 or RC16 or one of disposal operations D1 through D12, or DC15 to DC16, to the competent authority of the country of export that controls the shipment as an export of hazardous waste.  On or after the electronic import-export reporting compliance date, to USEPA electronically using USEPA's WIETS. The recovery and disposal operations in this paragraph are defined in 35 Ill. Adm. Code 722.181.

 

b)         Before transferring ownership or operation of a facility during its operating life, or of a disposal facility during the post-closure care period, the owner or operator must notify the new owner or operator in writing of the requirements of this Part and 35 Ill. Adm. Code 702 and 703 (also see 35 Ill. Adm. Code 703.155).

 

BOARD NOTE:  An owner's or operator's failure to notify the new owner or operator of the requirements of this Part in no way relieves the new owner or operator of his obligation to comply with all applicable requirements.

Section 725.113  General Waste Analysis

 

a)         Waste Analysis

 

1)         Before an owner or operator treats, stores, or disposes of any hazardous wastes, or non-hazardous wastes if applicable under Section 725.213(d), the owner or operator must obtain a detailed chemical and physical analysis of a representative sample of the wastes.  At a minimum, the analysis must contain all the information that must be known to treat, store, or dispose of the waste in accordance with this Part and 35 Ill. Adm. Code 728.

 

2)         The analysis may include data developed under 35 Ill. Adm. Code 721 and existing published or documented data on the hazardous waste or on waste generated from similar processes.

 

BOARD NOTE:  For example, the facility's record of analyses performed on the waste before the effective date of these regulations or studies conducted on hazardous waste generated from processes similar to that which generated the waste to be managed at the facility may be included in the data base required to comply with subsection (a)(1), except as otherwise specified in 35 Ill. Adm. Code 728.107(b) and (c). The owner or operator of an off-site facility may arrange for the generator of the hazardous waste to supply part or all of the information required by subsection (a)(1).  If the generator does not supply the information and the owner or operator chooses to accept a hazardous waste, the owner or operator is responsible for obtaining the information required to comply with this Section.

 

3)         The analysis must be repeated as necessary to ensure that it is accurate and up to date.  At a minimum, the analysis must be repeated as follows:

 

A)        When the owner or operator is notified or has reason to believe that the process or operation generating the hazardous waste, or non-hazardous waste if applicable under Section 725.213(d), has changed; and

 

B)        For off-site facilities, when the results of the inspection required in subsection (a)(4) indicate that the hazardous waste received at the facility does not match the waste designated on the accompanying manifest or shipping paper.

 

4)         The owner or operator of an off-site facility must inspect and, if necessary, analyze each hazardous waste movement received at the facility to determine whether it matches the identity of the waste specified on the accompanying manifest or shipping paper.

 

b)         The owner or operator must develop and follow a written waste analysis plan that describes the procedures that the owner or operator will carry out to comply with subsection (a).  The owner or operator must keep this plan at the facility.  At a minimum, the plan must specify the following:

 

1)         The parameters for which each hazardous waste, or non-hazardous waste if applicable under Section 725.213(d), will be analyzed and the rationale for the selection of these parameters (i.e., how analysis for these parameters will provide sufficient information on the waste's properties to comply with subsection (a)).

 

2)         The test methods that will be used to test for these parameters.

 

3)         The sampling method that will be used to obtain a representative sample of the waste to be analyzed. A representative sample may be obtained using either of the following methods:

 

A)        One of the sampling methods described in Appendix A to 35 Ill. Adm. Code 721, or

 

B)        An equivalent sampling method.

 

BOARD NOTE:  See 35 Ill. Adm. Code 720.120(c) for related discussion.

 

4)         The frequency with which the initial analysis of the waste will be reviewed or repeated to ensure that the analysis is accurate and up-to-date.

 

5)         For off-site facilities, the waste analyses that hazardous waste generators have agreed to supply.

 

6)         Where applicable, the methods that will be used to meet the additional waste analysis requirements for specific waste management methods, as specified in Sections 725.300, 725.325, 725.352, 725.373, 725.414, 725.441, 725.475, 725.502, 725.934(d), 725.963(d), and 725.984 and 35 Ill. Adm. Code 728.107.

 

7)         For surface impoundments exempted from land disposal restrictions under 35 Ill. Adm. Code 728.104(a), the procedures and schedules for the following:

 

A)        The sampling of impoundment contents;

 

B)        The analysis of test data; and

 

C)        The annual removal of residues that are not delisted under 35 Ill. Adm. Code 720.122 or that exhibit a characteristic of hazardous waste and either of the following is true:

 

i)          The waste residues do not meet the applicable treatment standards of Subpart D of 35 Ill. Adm. Code 728, or

 

ii)         Where no treatment standards have been established, the waste residues are prohibited from land disposal under 35 Ill. Adm. Code 728.132 or 728.139.

 

8)         For an owner or operator seeking an exemption to the air emission standards of Subpart CC of 35 Ill. Adm. Code 724 in accordance with Section 725.983:

 

A)        If direct measurement is used for the waste determination, the procedures and schedules for waste sampling and analysis, and the analysis of test data to verify the exemption.

 

B)        If knowledge of the waste is used for the waste determination, any information prepared by the facility owner or operator, or by the generator of the waste if the waste is received from off-site, that is used as the basis for knowledge of the waste.

 

c)         For off-site facilities, the waste analysis plan required in subsection (b) must also specify the procedures that will be used to inspect and, if necessary, analyze each movement of hazardous waste received at the facility to ensure that it matches the identity of the waste designated on the accompanying manifest or shipping paper.  At a minimum, the plan must describe the following:

 

1)         The procedures that will be used to determine the identity of each movement of waste managed at the facility;

 

2)         The sampling method that will be used to obtain a representative sample of the waste to be identified if the identification method includes sampling; and

 

3)         The procedures that the owner or operator of an off-site landfill receiving containerized hazardous waste will use to determine whether a hazardous waste generator or treater has added a biodegradable sorbent to the waste in the container.

SUBPART D: CONTINGENCY PLAN AND EMERGENCY PROCEDURES

 

Section 725.150  Applicability

 

The regulations in this Subpart D apply to owners and operators of all hazardous waste facilities, except as Section 725.101 provides otherwise.

 

(Source:  Amended at 29 Ill. Reg. 6389, effective April 22, 2005)

 

Section 725.151  Purpose and Implementation of Contingency Plan

 

a)         Each owner or operator must have a contingency plan for his facility.  The contingency plan must be designed to minimize hazards to human health or the environment from fires, explosions, or any unplanned sudden or non-sudden release of hazardous waste or hazardous waste constituents to air, soil, or surface water.

 

b)         The provisions of the plan must be carried out immediately whenever there is a fire, explosion, or release of hazardous waste or hazardous waste constituents that could threaten human health or the environment.

 

(Source:  Amended at 29 Ill. Reg. 6389, effective April 22, 2005)

 

Section 725.152  Content of Contingency Plan

 

a)         The contingency plan must describe the actions facility personnel must take to comply with Sections 725.151 and 725.156 in response to fires, explosions, or any unplanned sudden or non-sudden release of hazardous waste or hazardous waste constituents to air, soil, or surface water at the facility.

 

b)         If the owner or operator has already prepared a federal Spill Prevention Control and Countermeasures (SPCC) Plan in accordance with 40 CFR 112, or some other emergency or contingency plan, it needs only amend that plan to incorporate hazardous waste management provisions that are sufficient to comply with the requirements of this Part.  The owner or operator may develop one contingency plan that meets all regulatory requirements.  USEPA has recommended that the plan be based on the National Response Team's Integrated Contingency Plan Guidance (One Plan).  When modifications are made to non-RCRA provisions in an integrated contingency plan, the changes do not trigger the need for a RCRA permit modification.

 

BOARD NOTE:  The federal One Plan guidance appeared in the Federal Register at 61 Fed. Reg. 28642 (June 5, 1996), and was corrected at 61 Fed. Reg. 31103 (June 19, 1996).  USEPA, Office of Resource Conservation and Recovery, Chemical Emergency Preparedness and Prevention Office, has made these documents available on-line for examination and download at yosemite.epa.gov/oswer/Ceppoweb.nsf/content/serc-lepc-publications.htm.

 

c)         The plan must describe arrangements agreed to by local police department, fire departments, hospitals, contractors, and State and local emergency response teams to coordinate emergency services, pursuant to Section 725.137.

 

d)         The plan must list names, addresses, and phone numbers (office and home) of all persons qualified to act as emergency coordinator (see Section 725.155), and this list must be kept up to date. Where more than one person is listed one must be named as primary emergency coordinator and others must be listed in the order in which they will assume responsibility as alternates.

 

e)         The plan must include a list of all emergency equipment at the facility (such as fire extinguishing systems, spill control equipment, communications and alarm systems (internal and external), and decontamination equipment) where this equipment is required.  This list must be kept up to date. In addition, the plan must include the location and a physical description of each item on the list and a brief outline of its capabilities.

 

f)         The plan must include an evacuation plan for facility personnel where there is a possibility that evacuation could be necessary.  This plan must describe signals to be used to begin evacuation, evacuation routes, and alternate evacuation routes (in cases where the primary routes could be blocked by releases  of hazardous waste or fires).

 

(Source:  Amended at 35 Ill. Reg. 18052, effective October 14, 2011)

 

Section 725.153  Copies of Contingency Plan

 

The facility owner or operator must undertake each of the following actions with regard to copies of the contingency plan and all revisions to the plan:

 

a)         It must maintain a copy at the facility; and

 

b)         It must submit a copy to each local police department , fire department, hospital , and State and local emergency response team that may be called upon to provide emergency services at the facility.

 

(Source:  Amended at 31 Ill. Reg. 1031, effective December 20, 2006)

 

Section 725.154  Amendment of Contingency Plan

 

The contingency plan must be reviewed and immediately amended, if necessary, whenever any of the following occurs:

 

a)         Applicable regulations are revised;

 

b)         The plan fails in an emergency;

 

c)         The facility changes − in its design, construction, operation, maintenance, or other circumstances − in a way that materially increases the potential for fires, explosions, or releases of hazardous waste or hazardous waste constituents or changes the response necessary in an emergency;

 

d)         The list of emergency coordinators changes; or

 

e)                  The list of emergency equipment changes.

 

(Source:  Amended at 33 Ill. Reg. 1155, effective December 30, 2008)

 

Section 725.155   Emergency Coordinator

 

At all times, there must be at least one employee either on the facility premises or on call (i.e., available to respond to an emergency by reaching the facility within a short period of time) with the responsibility for coordinating all emergency response measures.  This emergency coordinator must be thoroughly familiar with all aspects of the facility's contingency plan, all operations and activities at the facility, the location and characteristics of waste handled, the location of all records within the facility and the facility layout.  In addition, this person must have the authority to commit the resources needed to carry out the contingency plan.

 

BOARD NOTE:  The emergency coordinator's responsibilities are more fully spelled out in Section 725.156.  Applicable responsibilities for the emergency coordinator vary, depending on factors such as type and variety of wastes handled by the facility and type and complexity of the facility.

 

(Source:  Amended at 29 Ill. Reg. 6389, effective April 22, 2005)

 

Section 725.156  Emergency Procedures

 

a)         Whenever there is an imminent or actual emergency situation, the emergency coordinator (or his designee when the emergency coordinator is on call) must immediately do the following:

 

1)         He or she must activate internal facility alarms or communication systems, where applicable, to notify all facility personnel; and

 

2)         He or she must notify appropriate State or local agencies with designated response roles if their help is needed.

 

b)         Whenever there is a release, fire, or explosion, the emergency coordinator must immediately identify the character, exact source, amount, and areal extent of any released materials. He or she may do this by observation or review of facility records or manifests and, if necessary, by chemical analysis.

 

c)         Concurrently, the emergency coordinator must assess possible hazards to human health or the environment that may result from the release, fire, or explosion.  This assessment must consider both direct and indirect effects of the release, fire, or explosion (e.g., the effects of any toxic, irritating, or asphyxiating gases that are generated, or the effects of any hazardous surface water run-off from water or chemical agents used to control fire and heat-induced explosions).

 

d)         If the emergency coordinator determines that the facility has had a release, fire, or explosion that could threaten human health or the environment outside the facility, the emergency coordinator must report those findings as follows:

 

1)         If the assessment indicates that evacuation of local areas may be advisable, the emergency coordinator must immediately notify appropriate local authorities.  The emergency coordinator must be available to help appropriate officials decide whether local areas should be evacuated; and

 

2)         The emergency coordinator must immediately notify either the government official designated as the on-scene coordinator for that geographical area or the National Response Center (using their 24-hour toll free number 800-424-8802).  The report must include the following:

 

A)        The name and telephone number of the reporter;

 

B)        The name and address of facility;

 

C)        The time and type of incident (e.g., release, fire, etc.);

 

D)        The name and quantity of materials involved, to the extent known;

 

E)        The extent of injuries, if any; and

 

F)         The possible hazards to human health or the environment outside the facility.

 

e)         During an emergency the emergency coordinator must take all reasonable measures necessary to ensure that fires, explosions, and releases do not occur, recur, or spread to other hazardous waste at the facility.  These measures must include, where applicable, stopping processes and operations, collecting and containing released waste, and removing or isolating containers.

 

f)         If the facility stops operations in response to a fire, explosion or release, the emergency coordinator must monitor for leaks, pressure buildup, gas generation, or ruptures in valves, pipes, or other equipment, wherever this is appropriate.

 

g)         Immediately after an emergency, the emergency coordinator must provide for treating, storing, or disposing of recovered waste, contaminated soil, or surface water, or any other material that results from a release, fire, or explosion at the facility.

 

            BOARD NOTE:  Unless the owner or operator can demonstrate in accordance with 35 Ill. Adm. Code 721.103(d) or (e) that the recovered material is not a hazardous waste, the owner or operator becomes a generator of hazardous waste and must manage it in accordance with all applicable requirements of 35 Ill. Adm. Code 722, 723, and 725.

 

h)         The emergency coordinator must ensure that, in the affected areas of the facility, the following occur:

 

1)         No waste that may be incompatible with the released material is treated, stored, or disposed of until cleanup procedures are completed; and

 

2)         All emergency equipment listed in the contingency plan is cleaned and fit for its intended use before operations are resumed.

 

i)          The owner or operator must note in the operating record the time, date, and details of any incident that requires implementing the contingency plan.  Within 15 days after the incident, it must submit a written report on the incident to the Agency.  The report must include the following information:

 

1)         The name, address, and telephone number of the owner or operator;

 

2)         The name, address, and telephone number of the facility;

 

3)         The date, time, and type of incident (e.g., fire, explosion, etc.);

 

4)         The name and quantity of materials involved;

 

5)         The extent of injuries, if any;

 

6)         An assessment of actual or potential hazards to human health or the environment, where this is applicable; and

 

7)         The estimated quantity and disposition of recovered material that resulted from the incident.

SUBPART E: MANIFEST SYSTEM, RECORDKEEPING, AND REPORTING

 

Section 725.170  Applicability

 

The regulations in this Subpart E apply to owners and operators of both on-site and off-site facilities, except as Section 725.101 provides otherwise.  Sections 725.171, 725.172, and 725.176 do not apply to owners and operators of on-site facilities that do not receive any hazardous waste from off-site sources, nor do they apply to owners and operators of off-site facilities with respect to waste military munitions exempted from manifest requirements under 35 Ill. Adm. Code 726.303(a).

 

(Source:  Amended at 35 Ill. Reg. 18052, effective October 14, 2011)

 

Section 725.171  Use of Manifest System

 

a)         Receipt of Manifested Hazardous Waste

 

1)         If a facility receives hazardous waste accompanied by a manifest, the owner, operator, or its agent must sign and date the manifest, as indicated in subsection (a)(2), to certify that the hazardous waste covered by the manifest was received, that the hazardous waste was received except as noted in the discrepancy space of the manifest, or that the hazardous waste was rejected as noted in the manifest discrepancy space.

 

2)         If a facility receives a hazardous waste shipment accompanied by a manifest, the owner, operator, or its agent must do the following:

 

A)        The owner, operator, or agent must sign and date, by hand, each copy of the manifest;

 

B)        The owner, operator, or agent must note any discrepancies (as defined in 35 Ill. Adm. Code 724.172) on each copy of the manifest;

 

C)        The owner, operator, or agent must immediately give the transporter at least one copy of the manifest;

 

D)        The owner, operator, or agent must send a copy (Page 3) of the manifest to the generator within 30 days after delivery;

 

E)        Paper manifest submission requirements are the following:

 

i)          The owner, operator, or agent must send the top copy (Page 1) of any paper manifest and any paper continuation sheet to the e-Manifest System for purposes of data entry and processing.  In lieu of submitting the paper copy to the e-Manifest System operator, the owner or operator may transmit to the e-Manifest System operator an image file of Page 1 of the manifest and any continuation sheet, or both a data string file and the image file corresponding to Page 1 of the manifest and any continuation sheet, within 30 days after the date of delivery.  Submissions of copies to the e-Manifest System must be made at the mailing address or electronic mail/submission address specified at the e-Manifest program website's directory of services.  Beginning on June 30, 2021, USEPA will not accept mailed paper manifests from facilities for processing in the e-Manifest System; and

 

ii)         Options for Compliance on June 30, 2021.  Beginning on June 30, 2021, the requirement to submit the top copy (Page 1) of the paper manifest and any paper continuation sheet to the e-Manifest System for purposes of data entry and processing may be met by the owner or operator only by transmitting to the e-Manifest System an image file of Page 1 of the manifest and any continuation sheet, or by transmitting to the e-Manifest System both a data file and the image file corresponding to Page 1 of the manifest and any continuation sheet, within 30 days after the date of delivery.  Submissions of copies to the e-Manifest System must be made to the electronic mail/submission address specified at the e-Manifest program website's directory of services.  Beginning on June 30, 2021, USEPA will not accept mailed paper manifests from facilities for processing in the e-Manifest System; and

 

F)         The owner, operator, or agent must retain at the facility a copy of each manifest for at least three years after the date of delivery.

 

3)         The owner or operator of a facility that receives hazardous waste subject to Subpart H of 35 Ill. Adm. Code 722 from a foreign source must:

 

A)        Additionally list the relevant consent number from consent documentation supplied by USEPA to the facility for each waste listed on the hazardous waste manifest (USEPA Form 8700-22), matched to the relevant list number for the waste from block 9b.  If additional space is needed, the owner or operator should use Continuation Sheets (USEPA Form 8700-22A); and

 

B)        Send a copy of the manifest to USEPA using the addresses listed in 35 Ill. Adm. Code 722.182(e) within 30 days of delivery until the facility can submit such a copy to the e-Manifest system per subsection (a)(2)(E).

 

b)         If a facility receives from a rail or water (bulk shipment) transporter hazardous waste that is accompanied by a shipping paper containing all the information required on the manifest (excluding the USEPA identification numbers, generator certification, and signatures), the owner or operator or its agent must do each of the following:

 

1)         It must sign and date each copy of the manifest or shipping paper (if the manifest has not been received) to certify that the hazardous waste covered by the manifest or shipping paper was received;

 

2)         It must note any significant discrepancies, as defined in Section 725.172(a), in the manifest or shipping paper (if the manifest has not been received) on each copy of the manifest or shipping paper;

 

            BOARD NOTE:  The owner or operator of a facility whose procedures under Section 725.113(c) include waste analysis need not perform that analysis before signing the shipping paper and giving it to the transporter.  Section 725.172(b), however, requires reporting an unreconciled discrepancy discovered during later analysis.

 

3)         It must immediately give the rail or water (bulk shipment) transporter at least one copy of the manifest or shipping paper (if the manifest has not been received);

 

4)         The owner or operator must send a copy of the signed and dated manifest or a signed and dated copy of the shipping paper (if the manifest has not been received within 30 days after delivery) to the generator within 30 days after the delivery; and

 

            BOARD NOTE:  35 Ill. Adm. Code 722.123(c) requires the generator to send three copies of the manifest to the facility when hazardous waste is sent by rail or water (bulk shipment).  

 

5)         Retain at the facility a copy of the manifest and shipping paper (if signed in lieu of the manifest at the time of delivery) for at least three years from the date of delivery.

 

c)         Whenever a shipment of hazardous waste is initiated from a facility, the owner or operator of that facility must comply with the requirements of 35 Ill. Adm. Code 722.  The provisions of 35 Ill. Adm. Code 722.115, 722.116, and 722.117 apply to the on-site accumulation of hazardous wastes by generators.  Therefore, the provisions of 35 Ill. Adm. Code 722.115, 722.116, and 722.117 only apply to an owner or operator that ships hazardous waste that it generated at that facility or operating as an LQG consolidating hazardous waste from VSQGs under 35 Ill. Adm. Code 722.117(f).

 

d)         As required by 40 CFR 262.84(d)(2)(O), within three working days after the receipt of a shipment subject to Subpart H of 35 Ill. Adm. Code 722, the owner or operator of a facility must provide a copy of the movement document bearing all required signatures to the foreign exporter and to the competent authorities of the countries of export and transit that control the shipment as an export or transit of hazardous waste.  On or after the electronic import-export reporting compliance date, to USEPA electronically using USEPA's WIETS.  The original copy of the tracking document must be maintained at the facility for at least three years from the date of signature.  The owner or operator of a facility may satisfy this recordkeeping requirement by retaining electronically submitted documents in the facility's account on USEPA's WIETS, provided that copies are readily available for viewing and production if requested by any USEPA or authorized state inspector.  No owner or operator of a facility may be held liable for the inability to produce the documents for inspection under this section if the owner or operator of a facility can demonstrate that the inability to produce the document is due exclusively to technical difficulty with USEPA's WIETS, for which the owner or operator of a facility bears no responsibility.

 

e)         A facility must determine whether the consignment state for a shipment regulates any additional wastes (beyond those regulated federally) as hazardous wastes under its state hazardous waste program.  A facility must also determine whether the consignment state or generator state requires the facility to submit any copies of the manifest to that state.

 

f)         Legal Equivalence to Paper Manifests.  E-Manifests that are obtained, completed, transmitted in accordance with 35 Ill. Adm. Code 722.120(a)(3), and used in accordance with this Section in lieu of the paper manifest form are the legal equivalent of paper manifest forms bearing handwritten signatures, and satisfy for all purposes any requirement in 35 Ill. Adm. Code 720 through 728 to obtain, complete, sign, provide, use, or retain a manifest.

 

1)         Any requirement in 35 Ill. Adm. Code 720 through 728 for the owner or operator of a facility to sign a manifest or manifest certification by hand, or to obtain a handwritten signature, is satisfied by signing with or obtaining a valid and enforceable electronic signature within the meaning of 35 Ill. Adm. Code 722.125.

 

2)         Any requirement in 35 Ill. Adm. Code 720 through 728 to give, provide, send, forward, or to return to another person a copy of the manifest is satisfied when a copy of an e-Manifest is transmitted to the other person.

 

3)         Any requirement in 35 Ill. Adm. Code 720 through 728 for a manifest to accompany a hazardous waste shipment is satisfied when a copy of an e-Manifest is accessible during transportation and forwarded to the person or persons who are scheduled to receive delivery of the hazardous waste shipment.

 

4)         Any requirement in 35 Ill. Adm. Code 720 through 728 for an owner or operator to keep or retain a copy of each manifest is satisfied by the retention of the facility's e-Manifest copies in its account on the e-Manifest System, provided that such copies are readily available for viewing and production if requested by any USEPA or Agency inspector.

 

5)         No owner or operator may be held liable for the inability to produce an e-Manifest for inspection under this Section if the owner or operator can demonstrate that the inability to produce the e-Manifest is due exclusively to a technical difficulty with the e-Manifest System for which the owner or operator bears no responsibility.

 

g)         An owner or operator may participate in the e-Manifest System either by accessing the e-Manifest System from the owner's or operator's electronic equipment, or by accessing the e-Manifest System from portable equipment brought to the owner's or operator's site by the transporter that delivers the waste shipment to the facility.

 

h)         Special Procedures Applicable to Replacement Manifests.  If a facility receives hazardous waste that is accompanied by a paper replacement manifest for a manifest that was originated electronically, the following procedures apply to the delivery of the hazardous waste by the final transporter:

 

1)         Upon delivery of the hazardous waste to the designated facility, the owner or operator must sign and date each copy of the paper replacement manifest by hand in Item 20 (Designated Facility Certification of Receipt) and note any discrepancies in Item 18 (Discrepancy Indication Space) of the paper replacement manifest;

 

2)         The owner or operator of the facility must give back to the final transporter one copy of the paper replacement manifest;

 

3)         Within 30 days after delivery of the hazardous waste to the designated facility, the owner or operator of the facility must send one signed and dated copy of the paper replacement manifest to the generator and send an additional signed and dated copy of the paper replacement manifest to the e-Manifest System; and

 

4)         The owner or operator of the facility must retain at the facility one copy of the paper replacement manifest for at least three years after the date of delivery.

 

i)          Special Procedures Applicable to Electronic Signature Methods Undergoing Tests.  If an owner or operator using an e-Manifest signs this manifest electronically using an electronic signature method that is undergoing pilot or demonstration tests aimed at demonstrating the practicality or legal dependability of the signature method, the owner or operator must also sign with an ink signature the facility's certification of receipt or discrepancies on the printed copy of the manifest provided by the transporter.  Upon executing its ink signature on this printed copy, the owner or operator must retain this original copy among its records for at least three years after the date of delivery of the waste.

 

j)          Imposition of User Fee for e-Manifest Use 

 

1)         As prescribed in 40 CFR 265.1311, incorporated by reference in 35 Ill. Adm. Code 720.111, and determined in 40 CFR 265.1312, incorporated by reference in 35 Ill. Adm. Code 720.111, an owner or operator that is a user of the e-Manifest System must be assessed a user fee by USEPA for the submission and processing of each e-Manifest and paper manifest.  USEPA has stated that it would update the schedule of user fees and publish them to the user community, as provided in 40 CFR 265.1313, incorporated by reference in 35 Ill. Adm. Code 720.111.

 

2)         An owner or operator subject to user fees under this Section must make user fee payments in accordance with the requirements of 40 CFR 265.1314, incorporated by reference in 35 Ill. Adm. Code 720.111, subject to the informal fee dispute resolution process of 40 CFR 265.1316, incorporated by reference in 35 Ill. Adm. Code 720.111, and subject to the sanctions for delinquent payments under 40 CFR 265.1315, incorporated by reference in 35 Ill. Adm. Code 720.111.

 

k)         E-Manifest Signatures.  E-Manifest signatures must meet the criteria described in 35 Ill. Adm. Code 722.125.

 

l)          Post-Receipt Manifest Data Corrections.  After a facility has certified to the receipt of hazardous wastes by signing Item 20 of the manifest, any interested person (i.e., any waste handler shown on the manifest or the Agency) may submit any post-receipt data corrections at any time.

 

1)         An interested person must make all corrections to manifest data by electronic submission, either by directly entering corrected data to the web-based service provided in the e-Manifest System for such corrections, or by an upload of a data file containing data corrections relating to one or more previously submitted manifests.

 

2)         Each correction submission must include the following information:

 

A)        The Manifest Tracking Number and date of receipt by the facility of the original manifests for which data are being corrected;

 

B)        The item numbers of the original manifest that is the subject of the submitted corrections; and

 

C)        For each item number with corrected data, the data previously entered and the corresponding data as corrected by the correction submission.

 

3)         Each correction submission must include a statement that the person submitting the corrections certifies that, to the best of his or her knowledge or belief, the corrections that are included in the submission will cause the information reported about the previously received hazardous wastes to be true, accurate, and complete:

 

A)        The person must execute the certification statement with a valid electronic signature; and

 

B)        The person may submit a batch upload of data corrections under one certification statement.

 

4)         Upon receipt by the e-Manifest System of any correction submission, other interested persons shown on the manifest will be provided electronic notice of the submitter's corrections.

 

5)         Other interested persons shown on the manifest may respond to the submitter's corrections with comments to the submitter, or by submitting another correction to the e-Manifest System, certified by the respondent as specified in subsection (l)(3), and with notice of the corrections to other interested persons shown on the manifest.

Section 725.172  Manifest Discrepancies

 

a)         "Manifest discrepancies" are defined as any one of the following:

 

1)         Significant differences (as defined by subsection (b)) between the quantity or type of hazardous waste designated on the manifest or shipping paper, and the quantity and type of hazardous waste a facility actually receives;

 

2)         Rejected wastes, which may be a full or partial shipment of hazardous waste that the treatment, storage, or disposal facility cannot accept; or

 

3)         Container residues, which are residues that exceed the quantity limits for empty containers set forth in 35 Ill. Adm. Code 721.107(b).

 

b)         "Significant differences in quantity" are defined as the appropriate of the following:  for bulk waste, variations greater than 10 percent in weight; or, for batch waste, any variation in piece count, such as a discrepancy of one drum in a truckload.  "Significant differences in type" are defined as obvious differences that can be discovered by inspection or waste analysis, such as waste solvent substituted for waste acid, or as toxic constituents not reported on the manifest or shipping paper.

 

c)         Upon discovering a significant difference in quantity or type, the owner or operator must attempt to reconcile the discrepancy with the waste generator or transporter (e.g., with telephone conversations).  If the discrepancy is not resolved within 15 days after receiving the waste, the owner or operator must immediately submit to the Agency a letter describing the discrepancy and attempts to reconcile it, and a copy of the manifest or shipping paper at issue.

 

d)         Rejection of Hazardous Waste

 

1)         Upon rejecting waste or identifying a container residue that exceeds the quantity limits for empty containers set forth in 35 Ill. Adm. Code 721.107(b), the facility owner or operator must consult with the generator prior to forwarding the waste to another facility that can manage the waste.  If it is impossible to locate an alternative facility that can receive the waste, the facility owner or operator may return the rejected waste or residue to the generator.  The facility owner or operator must send the waste to the alternative facility or to the generator within 60 days after the rejection or the container residue identification.

 

2)         While the facility owner or operator is making arrangements for forwarding rejected wastes or residues to another facility under this Section, it must ensure that either the delivering transporter retains custody of the waste, or the facility owner or operator must provide for secure, temporary custody of the waste, pending delivery of the waste to the first transporter designated on the manifest prepared under subsection (e) or (f).

 

e)         Except as provided in subsection (e)(7), for full or partial load rejections and residues that are to be sent off-site to an alternate facility, the facility owner or operator is required to prepare a new manifest in accordance with 35 Ill. Adm. Code 722.120(a) and the instructions set forth in subsections (e)(1) through (e)(6):

 

1)         The facility owner or operator must write the generator's USEPA identification number in Item 1 of the new manifest.  The facility owner or operator must write the generator's name and mailing address in Item 5 of the new manifest.  If the mailing address is different from the generator's site address, then the facility owner or operator must write the generator's site address in the designated space in Item 5.

 

2)         The facility owner or operator must write the name of the alternate designated facility and the facility's USEPA identification number in the designated facility block (Item 8) of the new manifest.

 

3)         The facility owner or operator must copy the manifest tracking number found in Item 4 of the old manifest to the Special Handling and Additional Information Block of the new manifest, and indicate that the shipment is a residue or rejected waste from the previous shipment.

 

4)         The facility owner or operator must copy the manifest tracking number found in Item 4 of the new manifest to the manifest reference number line in the Discrepancy Block of the old manifest (Item 18a).

7)         For full load rejections that are made while the transporter remains present at the facility, the facility owner or operator may forward the rejected shipment to the alternate facility by completing Item 18b of the original manifest and supplying the information on the next destination facility in the Alternate Facility space.  The facility owner or operator must retain a copy of this manifest for its records, and then give the remaining copies of the manifest to the transporter to accompany the shipment. If the original manifest is not used, then the facility owner or operator must use a new manifest and comply with subsections (e)(1) through (e)(6).

 

f)         Except as provided in subsection (f)(7), for rejected wastes and residues that must be sent back to the generator, the facility owner or operator is required to prepare a new manifest in accordance with 35 Ill. Adm. Code 722.120(a) and the instructions set forth in subsections (f)(1) through (f)(6) and (f)(8):

 

1)         The facility owner or operator must write the facility's USEPA identification number in Item 1 of the new manifest. The facility owner or operator must write the facility's name and mailing address in Item 5 of the new manifest. If the mailing address is different from the facility's site address, then the facility owner or operator must write the facility's site address in the designated space for Item 5 of the new manifest.

 

2)         The facility owner or operator must write the name of the initial generator and the generator's USEPA identification number in the designated facility block (Item 8) of the new manifest.

7)         For full load rejections that are made while the transporter remains at the facility, the facility owner or operator may return the shipment to the generator with the original manifest by completing Item 18b of the manifest and supplying the generator's information in the Alternate Facility space.  The facility owner or operator must retain a copy for its records and then give the remaining copies of the manifest to the transporter to accompany the shipment. If the original manifest is not used, then the facility owner or operator must use a new manifest and comply with subsections (f)(1) through (f)(6) and (f)(8).

 

8)         For full or partial load rejections and container residues contained in non-empty containers that are returned to the generator, the facility owner or operator must also comply with the exception reporting requirements in Section 722.142(a).

 

g)         If a facility owner or operator rejects a waste or identifies a container residue that exceeds the quantity limits for empty containers set forth in 35 Ill. Adm. Code 721.107(b) after it has signed, dated, and returned a copy of the manifest to the delivering transporter or to the generator, the facility owner or operator must amend its copy of the manifest to indicate the rejected wastes or residues in the discrepancy space of the amended manifest.  The facility owner or operator must also copy the manifest tracking number from Item 4 of the new manifest to the Discrepancy space of the amended manifest, and must re-sign and date the manifest to certify to the information as amended.  The facility owner or operator must retain the amended manifest for at least three years from the date of amendment, and must, within 30 days, send a copy of the amended manifest to the transporter and generator that received copies prior to their being amended.

SUBPART F: GROUNDWATER MONITORING

 

Section 725.190  Applicability

 

a)         The owner or operator of a surface impoundment, landfill, or land treatment facility that is used to manage hazardous waste must implement a groundwater monitoring program capable of determining the facility's impact on the quality of groundwater in the uppermost aquifer underlying the facility, except as Section 725.101 and subsection (c) provide otherwise.

 

b)         Except as subsections (c) and (d) provide otherwise, the owner or operator must install, operate, and maintain a groundwater monitoring system that meets the requirements of Section 725.191 and must comply with Sections 725.192 through 725.194.  This groundwater monitoring program must be carried out during the active life of the facility and for disposal facilities during the post-closure care period as well.

 

c)         All or part of the groundwater monitoring requirements of this Subpart F may be waived if the owner or operator can demonstrate that there is a low potential for migration of hazardous waste or hazardous waste constituents from the facility via the uppermost aquifer to water supply wells (domestic, industrial, or agricultural) or to surface water.  This demonstration must be in writing and must be kept at the facility. This demonstration must be certified by a qualified geologist or geotechnical engineer and must establish the following:

 

1)         The potential for migration of hazardous waste or hazardous waste constituents from the facility to the uppermost aquifer by an evaluation of the following information:

 

A)        A water balance of precipitation, evapotranspiration, run-off, and infiltration; and

 

B)        Unsaturated zone characteristics (i.e., geologic materials, physical properties, and depth to ground water); and

 

2)         The potential for hazardous waste or hazardous waste constituents that enter the uppermost aquifer to migrate to a water supply well or surface water by an evaluation of the following information:

 

A)        Saturated zone characteristics (i.e., geologic materials, physical properties, and rate of groundwater flow); and

 

B)        The proximity of the facility to water supply wells or surface water.

 

d)         If an owner or operator assumes (or knows) that groundwater monitoring of indicator parameters in accordance with Sections 725.191 and 725.192 would show statistically significant increases (or decreases in the case of pH) when evaluated pursuant to Section 725.193(b), it may install, operate, and maintain an alternate groundwater monitoring system (other than the one described in Sections 725.191 and 725.192).  If the owner or operator decides to use an alternate groundwater monitoring system, it must have done as follows:

 

1)         The owner or operator must develop a specific plan, certified by a qualified geologist or geotechnical engineer, that satisfies the requirements of federal 40 CFR 265.93(d)(3) for an alternate groundwater monitoring system.  This plan is to be placed in the facility's operating record and maintained until closure of the facility;

 

2)         The owner or operator must have initiated the determinations specified in federal 40 CFR 265.93(d)(4);

 

3)         The owner or operator must prepare a written report in accordance with Section 725.193(d)(5) and place it in the facility's operating record and maintain until closure of the facility;

 

4)         The owner or operator must continue to make the determinations specified in Section 725.193(d)(4) on a quarterly basis until final closure of the facility; and

 

5)         The owner or operator must comply with the recordkeeping and reporting requirements in Section 725.194(b).

 

e)         The groundwater monitoring requirements of this Subpart F may be waived with respect to any surface impoundment of which the following is true:

 

1)         The impoundment is used to neutralize wastes that are hazardous solely because they exhibit the corrosivity characteristic pursuant to 35 Ill. Adm. Code 721.122 or which are listed as hazardous wastes in Subpart D of 35 Ill. Adm. Code 721 only for this reason; and

 

2)         The impoundment contains no other hazardous wastes, if the owner or operator can demonstrate that there is no potential for migration of hazardous wastes from the impoundment.  The demonstration must establish, based upon consideration of the characteristics of the wastes and the impoundment, that the corrosive wastes will be neutralized to the extent that they no longer meet the corrosivity characteristic before they can migrate out of the impoundment. The demonstration must be in writing and must be certified by a qualified professional.

 

f)         A permit or enforceable document can contain alternative requirements for groundwater monitoring that replace all or part of the requirements of this Subpart F applicable to a regulated unit (as defined in 35 Ill. Adm. Code 724.190), as provided pursuant to 35 Ill. Adm. Code 703.161, where the Board has determined by an adjusted standard granted pursuant to Section 28.1 of the Act and Subpart D of 35 Ill. Adm. Code 104 the following:

 

1)         The regulated unit is situated among solid waste management units (or areas of concern), a release has occurred, and both the regulated unit and one or more solid waste management units (or areas of concern) are likely to have contributed to the release; and

 

2)         It is not necessary to apply the groundwater monitoring requirements of this Subpart F because the alternative requirements will adequately protect human health and the environment.  The alternative standards for the regulated unit must meet the requirements of 35 Ill. Adm. Code 724.201(a).

Section 725.191  Groundwater Monitoring System

 

a)         A groundwater monitoring system must be capable of yielding groundwater samples for analysis and must consist of the following components:

 

1)         Monitoring wells (at least one) installed hydraulically upgradient (i.e., in the direction of increasing static head) from the limit of the waste management area. Their number, locations, and depths must be sufficient to yield groundwater samples that fulfill both of the following requirements:

 

A)        The samples are representative of background groundwater quality in the uppermost aquifer near the facility; and

 

B)        The samples are not affected by the facility; and

 

2)         Monitoring wells (at least three) installed hydraulically downgradient (i.e., in the direction of decreasing static head) at the limit of the waste management area.  Their number, locations, and depths must ensure that they immediately detect any statistically significant amounts of hazardous waste or hazardous waste constituents that migrate from the waste management area to the uppermost aquifer.

 

b)         Separate monitoring systems for each waste management component of a facility are not required provided that provisions for sampling upgradient and downgradient water quality will detect any discharge from the waste management area.

 

1)         In the case of a facility consisting of only one surface impoundment, landfill, or land treatment area, the waste management area is described by the waste boundary (perimeter).

 

2)         In the case of a facility consisting of more than one surface impoundment, landfill, or land treatment area, the waste management area is described by the imaginary boundary line that circumscribes the several waste management components.

 

3)         The facility owner or operator may demonstrate that an alternate hydraulically downgradient monitoring well location will meet the criteria outlined below.  The demonstration must be in writing and kept at the facility.  The demonstration must be certified by a qualified groundwater scientist and establish each of the following:

 

A)        That an existing physical obstacle prevents monitoring well installation at the hydraulically downgradient limit of the waste management area.

 

B)        That the selected alternate downgradient location is as close to the limit of the waste management area as practical.

 

C)        That the alternate location ensures detection as early as possible of any statistically significant amounts of hazardous waste or hazardous waste constituents that migrate from the waste management area to the uppermost aquifer.

 

D)        Lateral expansion, new, or replacement units are not eligible for an alternate downgradient location under this subsection (b)(3).

 

c)         All monitoring wells must be cased in a manner that maintains the integrity of the monitoring well bore hole.  This casing must be screened or perforated and packed with gravel or sand where necessary to enable sample collection at depths where appropriate aquifer flow  zones  exist.  The annular space (i.e., the space between the bore hole and well casing) above the sampling depth must be sealed with a suitable material (e.g., cement grout or bentonite slurry) to prevent contamination of samples and the groundwater.

Section 725.192  Sampling and Analysis

 

a)         The owner or operator must obtain and analyze samples from the installed groundwater monitoring system.  The owner or operator must develop and follow a groundwater sampling and analysis plan. The owner or operator must keep this plan at the facility.  The plan must include procedures and techniques for each of the following:

 

1)         Sample collection;

 

2)         Sample preservation and shipment;

 

3)         Analytical procedures; and

 

4)         Chain of custody control.

 

BOARD NOTE:  See "Procedures Manual For Ground Water Monitoring At Solid Waste Disposal Facilities", USEPA document number EPA-530/SW-611, and "Methods for Chemical Analysis of Water and Wastes", USEPA document number EPA-600/4-79-020, incorporated by reference in 35 Ill. Adm. Code 720.111(a), for discussions of sampling and analysis procedures.

 

b)         The owner or operator must determine the concentration or value of the following parameters in groundwater samples in accordance with subsections (c) and (d):

2)         The following parameters establishing groundwater quality:

 

A)        Chloride,

 

B)        Iron,

 

C)        Manganese,

 

D)        Phenols,

 

E)        Sodium, and

 

F)         Sulfate.

 

BOARD NOTE:  These parameters are to be used as a basis for comparison in the event a groundwater quality assessment is required under Section 725.193(d).

 

3)         The following parameters used as indicators of groundwater contamination:

 

A)        pH,

 

B)        Specific Conductance,

 

C)        Total Organic Carbon, and

 

D)        Total Organic Halogen.

 

c)         Establishing Background Concentrations

 

1)         For all monitoring wells, the owner or operator must establish initial background concentrations or values of all parameters specified in subsection (b). The owner or operator must do this quarterly for one year.

 

2)         For each of the indicator parameters specified in subsection (b)(3), the owner or operator must obtain at least four replicate measurements for each sample and determine the initial background arithmetic mean and variance by pooling the replicate measurements for the respective parameter concentrations or values in samples obtained from upgradient wells during the first year.

 

d)         After the first year, the owner or operator must sample all monitoring wells and analyze the samples with the following frequencies:

 

1)         Samples collected to establish groundwater quality must be obtained and analyzed for the parameters specified in subsection (b)(2) at least annually.

 

2)         Samples collected to indicate groundwater contamination must be obtained and analyzed for the parameters specified in subsection (b)(3) at least semi-annually.

(Source:  Amended at 42 Ill. Reg. 23725, effective November 19, 2018)

 

Section 725.193  Preparation, Evaluation, and Response

 

a)         The owner or operator must prepare an outline of a groundwater quality assessment program.  The outline must describe a more comprehensive groundwater monitoring program (than that described in Sections 725.191 and 725.192) capable of determining each of the following:

 

1)         Whether hazardous waste or hazardous waste constituents have entered the groundwater;

 

2)         The rate and extent of migration of hazardous waste or hazardous waste constituents in the groundwater; and

 

3)         The concentrations of hazardous waste or hazardous waste constituents in the groundwater.

 

b)         For each indicator parameter specified in Section 725.192(b)(3), the owner or operator must calculate the arithmetic mean and variance, based on at least four replicate measurements on each sample, for each well monitored in accordance with Section 725.192(d)(2) and compare  these results  with its initial background arithmetic mean.  The comparison must consider individually each of  the wells in the monitoring system and must use the Student's t-test at the 0.01 level of significance (see Appendix D) to determine statistically significant increases (and decreases, in the case of pH) over initial background.

 

c)         Well Comparisons

 

1)         If the comparisons for the upgradient wells made under subsection (b) show a significant increase (or pH decrease) the owner or operator must submit this information in accordance with Section 725.194(a)(2)(B).

 

2)         If the comparisons for downgradient wells made under subsection (b) show a significant increase (or pH decrease) the owner or operator must then immediately obtain additional groundwater samples for those downgradient wells where a significant difference was detected, split the samples in two and obtain analyses of all additional samples to determine whether the significant difference was a result of laboratory error.

 

d)         Notice to the Agency

 

1)         If the analyses performed under subsection (c)(2) confirm the significant increase (or pH decrease) the owner or operator must provide written notice to the Agency – within seven days after the date of such confirmation – that the facility may be affecting groundwater quality.

 

2)         Within 15 days after the notification under subsection (d)(1), the owner or operator must develop a specific plan, based on the outline  required under subsection (a) and certified by a qualified geologist or geotechnical engineer for a groundwater quality assessment at the facility.  This plan must be placed in the facility operating record and be maintained until closure of the facility.

 

3)         The plan to be submitted under Section 725.190(d)(1) or subsection (d)(2) must specify all of the following:

 

A)        The number, location, and depth of wells;

 

B)        Sampling and analytical methods for those hazardous wastes or hazardous waste constituents in the facility;

 

C)        Evaluation procedures, including any use of previously gathered groundwater quality information; and

 

D)        A schedule of implementation.

 

4)         The owner or operator must implement the groundwater quality assessment plan that satisfies the requirements of subsection (d)(3) and, at a minimum, determine each of the following:

 

A)        The rate and extent of migration of the hazardous waste or hazardous waste constituents in the groundwater; and

 

B)        The concentrations of the hazardous waste or hazardous waste constituents in the groundwater.

 

5)         The owner or operator must make his first determination under subsection (d)(4), as soon as technically feasible, and prepare a report containing an assessment of the groundwater quality.  This report must be placed in the facility operating record and be maintained until closure of the facility.

 

6)         If the owner or operator determines, based on the results of the first determination under subsection (d)(4), that no hazardous waste  or hazardous waste constituents from the facility have entered the groundwater, then he may reinstate the indicator evaluation program described in Section 725.192 and subsection (b).  If the owner or operator reinstates the indicator evaluation program, he must so notify the Agency in the report submitted under subsection (d)(5).

 

7)         If the owner or operator determines, based on the first determination under subsection (d)(4), that hazardous waste or hazardous waste constituents from the facility have entered the groundwater, then the owner or operator must do either of the following:

 

A)        It must continue to make the determinations required under subsection (d)(4) on a quarterly basis until final closure of the facility if the groundwater quality assessment plan was implemented prior to final closure of the facility; or

 

B)        It may cease to make the determinations required under subsection (d)(4) if the groundwater quality assessment plan was implemented during the post-closure care period.

 

e)         Notwithstanding any other provision of this Subpart F, any groundwater quality assessment to satisfy the requirements of subsection (d)(4) that is initiated prior to final closure of the facility must be completed and reported in accordance with subsection (d)(5).

 

f)         Unless the groundwater is monitored to satisfy the requirements of subsection (d)(4) at least annually the owner or operator must evaluate the data on groundwater surface elevations obtained under Section 725.192(e) to determine whether the requirements under Section 725.191(a) for locating the monitoring wells continues to be satisfied.  If the evaluation shows that Section 725.191(a) is no longer satisfied, the owner or operator must immediately modify the number, location, or depth of the monitoring wells to bring the groundwater monitoring system into compliance with this requirement.

a)         Post-Closure Care

 

1)         Post-closure care for each hazardous waste management unit subject to the requirements of Sections 725.217 through 725.220 must begin after completion of closure of the unit and continue for 30 years after that date. It must consist of at least the following:

 

A)        Monitoring and reporting in accordance with the requirements of Subparts F, K, L, M, and N; and

 

B)        Maintenance and monitoring of waste containment systems in accordance with the requirements of Subparts F, K, L, M, and N.

 

2)         Any time preceding closure of a hazardous waste management unit subject to post-closure care requirements or final closure, or any time during the post-closure period for a particular hazardous waste disposal unit, the Board will, by an adjusted standard granted pursuant to Section 28.1 of the Act and Subpart D of 35 Ill. Adm. Code 104 or by an order in some other appropriate type of proceeding (e.g., an enforcement proceeding), do the following:

 

A)        Shorten the post-closure care period applicable to the hazardous waste management unit, or facility, if all disposal units have been closed, if the Board finds that the reduced period is sufficient to adequately protect human health and the environment (e.g., leachate or groundwater monitoring results; characteristics of the hazardous waste; application of advanced technology; or alternative disposal, treatment, or re-use techniques indicate that the hazardous waste management unit or facility is secure); or

 

B)        Extend the post-closure care period applicable to the hazardous waste management unit or facility, if the Board finds that the extended period is necessary to adequately protect human health and the environment (e.g., leachate or groundwater monitoring results indicate a potential for migration of hazardous wastes at levels that may be harmful to human health and the environment).

 

3)         As provided by Section 725.218(i), the Board will utilize site-specific rulemaking to adjust the length of the post-closure care period.

 

b)         The Agency must require, at partial or final closure, continuation of any of the security requirements of Section 725.214 during part or all of the post-closure period when either of the following occurs:

 

1)         Hazardous wastes may remain exposed after completion of partial or final closure; or

 

2)         Access by the public or domestic livestock may pose a hazard to human health.

 

c)         Post-closure use of property on or in which hazardous wastes remain after partial or final closure must never be allowed to disturb the integrity of the final cover, liners, or any other components of any containment system or the function of the facility's monitoring systems, unless the Agency determines either of the following with respect to the disturbance:

 

1)         It is necessary to the proposed use of the property, and will not increase the potential hazard to human health or the environment; or

 

2)         It is necessary to reduce a threat to human health or the environment.

 

d)         All post-closure care activities must be performed in accordance with the provisions of the approved post-closure plan, as specified in Section 725.218.

Section 725.218  Post-Closure Care Plan; Amendment of Plan

 

a)         Written Plan. The owner or operator of a hazardous waste disposal unit must have a written post-closure care plan.  An owner or operator of a surface impoundment or waste pile that intends to remove all hazardous wastes at closure must prepare a post-closure care plan and submit it to the Agency within 90 days after the date that the owner or operator or Agency determines that the hazardous waste management unit or facility must be closed as a landfill, subject to the requirements of Sections 725.217 through 725.220.

 

b)         Until final closure of the facility, a copy of the most current post-closure care plan must be furnished to the Agency upon request, including request by mail.  In addition, for facilities without approved post-closure care plans, it must also be provided during site inspections, on the day of inspection, to any officer, employee, or representative of the Agency.  After final closure has been certified, the person or office specified in subsection (c)(3) must keep the approved post-closure care plan during the post-closure care period.

 

c)         For each hazardous waste management unit subject to the requirements of this Section, the post-closure care plan must identify the activities that will be carried on after closure of each disposal unit and the frequency of these activities and include the following minimal information:

 

1)         A description of the planned monitoring activities and frequencies at which they will be performed to comply with Subparts F, K, L, M, and N during the post-closure care period;

 

2)         A description of the planned maintenance activities and frequencies at which they will be performed to ensure the following:

 

A)        The integrity of the cap and final cover or other containment systems in accordance with the requirements of Subparts K, L, M, and N; and

 

B)        The function of the monitoring equipment in accordance with the requirements of Subparts F, K, L, M, and N;

 

3)         The name, address, and phone number of the person or office to contact about the hazardous waste disposal unit or facility during the post-closure care period;

 

4)         For a facility subject to Section 725.221, provisions that satisfy the requirements of Section 725.221(a)(1) and (a)(3); and

 

5)         For a facility where alternative requirements are established at a regulated unit under Section 725.190(f), 725.210(d), or 725.240(d), as provided under 35 Ill. Adm. Code 703.161, either the alternative requirements that apply to the regulated unit, or a reference to the enforceable document containing those requirements.

 

d)         Amendment of Plan.  The owner or operator may amend the post-closure care plan at any time during the active life of the facility or during the post-closure care period. An owner or operator with an approved post-closure care plan must submit a written request to the Agency to authorize a change to the approved plan.  The written request must include a copy of the amended post-closure care plan for approval by the Agency.

 

1)         The owner or operator must amend the post-closure care plan whenever the following occur:

 

A)        Changes in operating plans or facility design affect the post-closure care plan; or

 

B)        Events occur during the active life of the facility, including partial and final closures, that affect the post-closure care plan; and

 

C)        The owner or operator requests the establishment of alternative requirements to a regulated unit under Section 725.190(f), 725.210(d), or 725.240(d).

 

2)         The owner or operator must amend the post-closure care plan at least 60 days prior to the proposed changes in facility design or operation, or no later than 60 days after an unexpected event has occurred that has affected the post-closure care plan.

 

3)         An owner or operator with an approved post-closure care plan must submit the modified plan to the Agency at least 60 days prior to the proposed change in facility design or operation, or no more than 60 days after an unexpected event has occurred that has affected the post-closure care plan.  If an owner or operator of a surface impoundment or a waste pile that intended to remove all hazardous wastes at closure in accordance with Section 725.328(b) or 725.358(a) is required to close as a landfill in accordance with Section 725.410, the owner or operator must submit a post-closure care plan within 90 days after the determination by the owner or operator or Agency that the unit must be closed as a landfill.  If the amendment to the post-closure care plan is a Class 2 or 3 modification according to the criteria in 35 Ill. Adm. Code 703.280, the modification to the plan must be approved according to the procedures in subsection (f).

 

4)         The Agency may request modifications to the plan under the conditions described in subsection (d)(1). An owner or operator with an approved post-closure care plan must submit the modified plan no later than 60 days after the request from the Agency.  If the amendment to the plan is considered a Class 2 or 3 modification according to the criteria in 35 Ill. Adm. Code 703.280 the modifications to the post-closure care plan must be approved in accordance with the procedures in subsection (f).  If the Agency determines that an owner or operator of a surface impoundment or waste pile that intended to remove all hazardous wastes at closure must close the facility as a landfill, the owner or operator must submit a post-closure care plan for approval to the Agency within 90 days after the determination.

 

e)         The owner or operator of a facility with hazardous waste management units subject to these requirements must submit the post-closure care plan to the Agency at least 180 days before the date the owner or operator expects to begin partial or final closure of the first hazardous waste disposal unit.  The date when the owner or operator "expects to begin closure" of the first hazardous waste disposal unit must be either within 30 days after the date on which the hazardous waste management unit receives the known final volume of hazardous waste or, if there is a reasonable possibility that the hazardous waste management unit will receive additional hazardous wastes, no later than one year after the date on which the unit received the most recent volume of hazardous wastes. The owner or operator must submit the closure plan to the Agency no later than 15 days after either of the following:

 

1)         Termination of interim status (except when a permit is issued to the facility simultaneously with termination of interim status); or

 

2)         Issuance of a judicial decree or Board order to cease receiving wastes or close.

 

f)         Procedures

 

1)         Except as provided in subsection (f)(2), the Agency must provide the owner or operator and the public through a newspaper notice the opportunity to submit written comments on the post-closure care plan and request modifications to the plan, no later than 30 days after the date of the notice.  The Agency may also, in response to a request or at its own discretion, hold a public hearing whenever such a hearing might clarify one or more issues concerning the post-closure care plan.  The Agency must give public notice of the hearing at least 30 days before it occurs. (Public notice of the hearing may be given at the same time as notice of the opportunity for written public comments and the two notices may be combined.)  The Agency must approve, modify, or disapprove the plan within 90 days after its receipt.  If the Agency determines not to approve the plan, the Agency must provide the owner or operator with a detailed statement of reasons for the refusal and the owner or operator must modify the plan or submit a new plan for approval within 30 days after receiving such written statements.  The Agency must approve or modify this plan in writing within 60 days.  If the Agency modifies the plan, this modified plan becomes the approved post-closure care plan.  Any final Agency determination must ensure that the approved post-closure care plan is consistent with Sections 725.217 through 725.220. A copy of this modified plan with a detailed statement of reasons for the modifications must be mailed to the owner or operator.

 

2)         The Agency must not provide notice or the opportunity for public comment if, in a prior proceeding, the Board has ordered the modifications to the plan.

 

g)         The post-closure care plan and length of the post-closure care period may be modified at any time prior to the end of the post-closure care period in either of the following two ways:

 

1)         The owner or operator or any member of the public may petition to extend or reduce the post-closure care period applicable to a hazardous waste management unit or facility based on cause, or alter the requirements of the post-closure care period based on cause.

 

A)        The petition must include evidence demonstrating either of the following:

 

i)          The secure nature of the hazardous waste management unit or facility makes the post-closure care requirements unnecessary or supports reduction of the post-closure care period specified in the current post-closure care plan (e.g., leachate or groundwater monitoring results; characteristics of the waste; application of advanced technology; or alternative disposal, treatment, or re-use techniques indicate that the facility is secure), or

 

ii)         The requested extension in the post-closure care period or alteration of post-closure care requirements is necessary to prevent threats to human health and the environment (e.g., leachate or groundwater monitoring results indicate a potential for migration of hazardous wastes at levels that may be harmful to human health and the environment).

 

B)        These petitions must be considered only when they present new and relevant information not previously considered.

 

i)          Except as provided in subsection (g)(1)(B)(ii), whenever the Agency is considering a petition, it must provide the owner or operator and the public, through a newspaper notice, the opportunity to submit written comments within 30 days after the date of the notice.  The Agency must also, in response to a request or at its own discretion, hold a public hearing whenever a hearing might clarify one or more issues concerning the post-closure care plan.  The Agency must give the public notice of the hearing at least 30 days before it occurs.  (Public notice of the hearing may be given at the same time as notice of the opportunity for written public comments and the two notices may be combined.)  After considering the comments, the Agency must issue a final determination, based upon the criteria set forth in subsection (g)(1).

 

ii)         The Agency must not provide notice or the opportunity for public comment if, in a prior proceeding, the Board has ordered the modifications to the plan.

 

C)        If the Agency denies the petition, it must send the petitioner a brief written response giving a reason for the denial.

 

2)         The Agency must tentatively decide to modify the post-closure care plan if the Agency determines that it is necessary to prevent threats to human health and the environment.  The Agency may propose to extend or reduce the post-closure care period applicable to a hazardous waste management unit or facility based on cause or alter the requirements of the post-closure care period based on cause.

 

A)        The Agency must provide the owner or operator and the affected public, through a newspaper notice, the opportunity to submit written comments within 30 days after the date of the notice and the opportunity for a public hearing as in subsection (g)(1)(B).  After considering the comments, the Agency must issue a final determination.

 

B)        The Agency must base its final determination upon the same criteria as required for petitions under subsection (g)(1)(A). A modification of the post-closure care plan may include, where appropriate, the temporary suspension rather than permanent deletion of one or more post-closure care requirements. At the end of the specified period of suspension, the Agency would then determine whether the requirements should be permanently discontinued or reinstated to prevent threats to human health and the environment.

 

h)         The Agency procedures described in Sections 725.212 through 725.219 are in the nature of permit amendments. Amendment of refusal to amend the plan is a permit denial for purposes of appeal pursuant to 35 Ill. Adm. Code 105.  The Agency must not amend permits in such a manner so that the permit would not conform with Board regulations.

 

i)          If any person seeks a closure or post-closure care plan that would not conform with Board regulations, such person must file a site-specific rulemaking petition pursuant to 35 Ill. Adm. Code 102 or a variance petition pursuant to Sections 35 through 38 of the Act and Subpart B of 35 Ill. Adm. Code 104.

Section 725.219  Post-Closure Notices

 

Within 90 days after closure is completed, the owner or operator of a disposal facility must submit to the County Recorder and to the Agency a survey plat indicating the location and dimensions of landfill cells or other disposal areas with respect to permanently surveyed benchmarks.  This plat must be prepared and certified by a professional land surveyor.  The plat filed with the County Recorder must contain a note, prominently displayed, that states the owner's or operator's obligation to restrict disturbance of the site as specified in Section 725.217(c).  In addition, the owner or operator must submit to the Agency and to the County Recorder a record of the type, location, and quantity of hazardous waste disposed of within each cell or area of the facility.  The owner or operator must identify the type, location, and quantity of hazardous wastes disposed of within each cell or area of the facility.  For wastes disposed of before these regulations were promulgated, the owner or operator must identify the type, location, and quantity of the wastes to the best of his knowledge and in accordance with any records the owner or operator has kept.

 

a)         No later than 60 days after certification of closure of each hazardous waste disposal unit, the owner or operator must submit to the County Recorder, to any local zoning authority, or any authority with jurisdiction over local land use, and to the Agency, a record of the type, location, and quantity of hazardous wastes disposed of within each cell or other disposal unit of the facility.  For hazardous wastes disposed of before January 12, 1981, the owner or operator must identify the type, location, and quantity of the hazardous wastes to the best of the owner or operator's knowledge and in accordance with any records the owner or operator has kept.

 

b)         Within 60 days after certification of closure of the first hazardous waste disposal unit and within 60 days after certification of closure of the last hazardous waste disposal unit, the owner or operator must do the following:

 

1)         Record, in accordance with Illinois law, a notation on the deed to the facility property, or on some other instrument that is normally examined during title search, that will in perpetuity notify any potential purchaser of the property of the following:

 

A)        The land has been used to manage hazardous wastes;

 

B)        Its use is restricted pursuant to Subpart G; and

 

C)        The survey plat and record of the type, location, and quantity of hazardous wastes disposed of within each cell or other hazardous waste disposal unit of the facility required by Sections 725.216 and 725.219(a) have been filed with the County Recorder, any local zoning authority, or any authority with jurisdiction over local land use, and with the Agency; and

 

2)         Submit to the Agency a certification signed by the owner or operator that the owner or operator has recorded the notation specified in subsection (b)(1), together with a copy of the document in which the notation has been placed.

 

c)         If the owner or operator or any subsequent owner of the land upon which a hazardous waste disposal unit was located wishes to remove hazardous wastes and hazardous waste residues; the liner, if any; and all contaminated structures, equipment, and soils, such person must request a modification to the approved post-closure plan in accordance with the requirements of Section 725.218(g).  The owner or operator must demonstrate that the removal of hazardous wastes will satisfy the criteria of Section 725.217(c). By removing hazardous waste, the owner or operator may become a generator of hazardous waste and must manage it in accordance with all applicable requirements of 35 Ill. Adm. Code 702, 703, 720 through 728, and 738.  If the owner or operator is granted approval to conduct the removal activities, the owner or operator may request that the Agency approve either of the following:

 

1)         Removal of the notation on the deed to the facility property or other instrument normally examined during title search, or

 

2)         Addition of a notation to the deed or instrument indicating the removal of the hazardous waste.

Section 725.220  Certification of Completion of Post-Closure Care

 

No later than 60 days after the completion of the established post-closure care period for each hazardous waste disposal unit, the owner or operator must submit to the Agency, by registered mail, a certification that the post-closure care period for the hazardous waste disposal unit was performed in accordance with the specifications in the approved post-closure plan.  The certification must be signed by the owner or operator and a qualified Professional Engineer.  Documentation supporting the Professional Engineer's certification must be furnished to the Agency upon request until the Agency releases the owner or operator from the financial assurance requirements for post-closure care under Section 725.245(h).

 

(Source:  Amended at 32 Ill. Reg. 12566, effective July 14, 2008)

 

Section 725.221  Alternative Post-Closure Care Requirements

 

a)         An owner or operator that is subject to the requirement to obtain a post-closure care permit under Subpart B of 35 Ill. Adm. Code 703 but which obtains an enforceable document in lieu of a post-closure permit, as provided in 35 Ill. Adm. Code 703.161, must comply with the following requirements:

 

1)         The requirements to submit information about the facility in 35 Ill. Adm. Code 703.214;

 

2)         The requirements for facility-wide corrective action in 35 Ill. Adm. Code 724.201; and

 

3)         The requirements of 35 Ill. Adm. Code 724.191 through 724.200.

 

b)         Implementation of Alternative Requirements

 

1)         Public Notice, Public Comments, and Public Hearing.

 

A)        In establishing alternative requirements in an enforceable document in lieu of a permit under this Section, the Board will assure a meaningful opportunity for public involvement that, at a minimum, includes public notice and opportunity for public comment, as provided under the relevant provisions of the Act:

 

i)          For a site-specific rulemaking, in Sections 27 and 28 of the Act.

 

ii)         For an adjusted standard, in Section 28.1 of the Act.

 

iii)        For a variance, in Sections 35 through 38 of the Act.

 

iv)        For an order issued pursuant to Section 33(a) of the Act, in Sections 31, 32, and 33 of the Act.

 

B)        When an owner or operator submits a plan to the Agency pursuant to an appropriate statutory or regulatory authority, the Agency must provide public notice and an opportunity for public hearing on the plan according to the requirements of Subparts D and E of 35 Ill. Adm. Code 705 as follows:

 

i)          When the Agency becomes involved in remedial action at the facility under regulations or in an enforcement action;

 

ii)         On the proposed preferred remedy and on the assumptions on which the remedy is based, especially those relating to land use and site characterization; and

 

iii)        At the time of a proposed decision that remedial action is complete at the facility.

 

C)        The requirements of subsection (b)(1)(B) must be met before the Agency may consider that the facility owner or operator has met the requirements of 35 Ill. Adm. Code 703.161, unless the facility qualifies for a modification to these public participation requirements under either of subsection (b)(2) or (b)(3).

 

2)         If the Agency determines that even a short delay in the implementation of a remedy would adversely affect human health or the environment, the Agency may delay compliance with the requirements of subsection (b)(1)(B) and immediately implement the remedy.  However, the Agency must assure involvement of the public at the earliest opportunity and, in all cases, upon making the decision that additional remedial action is not needed at the facility.

 

3)         The Agency may allow a remediation initiated prior to August 6, 1999 to substitute for corrective action required under a post-closure care permit.

g)         In the liability insurance requirements the terms "bodily injury" and "property damage" have the meanings given below.  The Board intends the meanings of other terms used in the liability insurance requirements to be consistent with their common meanings within the insurance industry.  The definitions given below of several of the terms are intended to assist in the understanding of these regulations and are not intended to limit their meanings in a way that conflicts with general insurance industry usage.

 

"Accidental occurrence" means an accident, including continuous or repeated exposure to conditions, that results in bodily injury or property damage neither expected nor intended from the standpoint of the insured.

 

"Bodily injury" means bodily injury, sickness, or disease sustained by a person, including death resulting from any of these at any time. However, this term does not include those liabilities that, consistent with standard insurance industry practices, are excluded from coverage in liability insurance policies for bodily injury.

 

BOARD NOTE:  Derived from the Insurance Services Office, Inc. definition of this term.

 

"Environmental damage" means the injurious presence in or upon land, the atmosphere or any watercourse or body of water of solid, liquid, gaseous, or thermal contaminants, irritants, or pollutants.

 

BOARD NOTE:  Derived from the Insurance Services Office, Inc. definition of this term.  This term is used in the definition of "pollution incident".

"Pollution incident" means emission, discharge, release or escape of pollutants into or upon land, the atmosphere, or any watercourse or body of water, provided that such emission, discharge, release, or escape results in "environmental damage". The entirety of any such emission, discharge, release, or escape must be deemed to be one "pollution incident".  "Waste" includes materials to be recycled, reconditioned, or reclaimed.  The term "pollution incident" includes an "occurrence".

 

BOARD NOTE:  Derived from the Insurance Services Office, Inc. definition of this term.  This definition is used in the definition of "property damage".

 

"Property damage" means as follows:

 

Either of the following:

 

Physical injury to, destruction of, or contamination of tangible property, including all resulting loss of use of that property; or

 

Loss of use of tangible property that is not physically injured, destroyed, or contaminated, but has been evacuated, withdrawn from use, or rendered inaccessible because of a "pollution incident".

 

This term does not include those liabilities that, consistent with standard insurance industry practices, are excluded from coverage in liability insurance policies for property damage.

 

BOARD NOTE:  Derived from the Insurance Services Office, Inc. definition of this term.

 

"Sudden accidental occurrence" means an occurrence that is not continuous or repeated in nature.

 

h)         "Substantial business relationship" means the extent of a business relationship necessary under applicable state law to make a guarantee contract issued incident to that relationship valid and enforceable.  A "substantial business relationship" must arise from a pattern of recent or ongoing business transactions, in addition to the guarantee itself, such that the Agency can reasonably determine that a substantial business relationship currently exists between the guarantor and the owner or operator that is adequate consideration to support the obligation of the guarantee relating to any liability towards a third-party.  "Applicable state law", as used in this subsection (h), means the laws of the State of Illinois and those of any sister state that govern the guarantee and the adequacy of the consideration.

 

BOARD NOTE:  Derived from 40 CFR 265.141(h) (2017) and the discussion at 53 Fed. Reg. 33938, 33941-33943 (Sep. 1, 1988).  This term is also independently defined in 35 Ill. Adm. Code 724.141(h) and 727.240(b)(8).  Any Agency determination that a substantial business relationship exists is subject to Board review pursuant to Section 40 of the Act.

Section 725.242  Cost Estimate for Closure

 

a)         The owner or operator must have a detailed written estimate, in current dollars, of the cost of closing the facility in accordance with the requirements in Sections 725.211 through 725.215 and applicable closure requirements of Sections 725.297, 725.328, 725.358, 725.380, 725.410, 725.451, 725.481, 725.504, and 725.1102.

 

1)         The estimate must equal the cost of final closure at the point in the facility's active life when the extent and manner of its operation would make closure the most expensive, as indicated by its closure plan (see Section 725.212(b)); and

 

2)         The closure cost estimate must be based on the costs to the owner or operator of hiring a third party to close the facility.  A third party is a party that is neither a parent nor a subsidiary of the owner or operator. (See definition of "parent corporation" in Section 725.241(d).) The owner or operator may use costs for on-site disposal if the owner or operator demonstrates that on-site disposal capacity will exist at all times over the life of the facility.

 

3)         The closure cost estimate must not incorporate any salvage value that may be realized by the sale of hazardous wastes, or non-hazardous wastes if permitted by the Agency pursuant to Section 725.213(d), facility structures or equipment, land or other facility assets at the time of partial or final closure.

 

4)         The owner or operator must not incorporate a zero cost for hazardous waste, or non-hazardous waste if permitted by the Agency pursuant to Section 725.213(d), that may have economic value.

 

b)         During the active life of the facility, the owner or operator must adjust the closure cost estimate for inflation within 60 days prior to the anniversary date of the establishment of the financial instruments used to comply with Section 725.243.  For an owner or operator using the financial test or corporate guarantee, the closure cost estimate must be updated for inflation within 30 days after the close of the firm's fiscal year and before submission of updated information to the Agency, as specified in Section 725.243(e)(5).  The adjustment may be made by recalculating the closure cost estimate in current dollars, or by using an inflation factor derived from the most recent annual Implicit Price Deflator for Gross National Product (Deflator), as published by the U.S. Department of Commerce in its Survey of Current Business, as specified in subsections (b)(1) and (b)(2).  The inflation factor is the result of dividing the latest published annual Deflator by the Deflator for the previous year.

 

1)         The first adjustment is made by multiplying the closure cost estimate by the inflation factor.  The result is the adjusted closure cost estimate.

 

2)         Subsequent adjustments are made by multiplying the latest adjusted closure cost estimate by the latest inflation factor.

 

BOARD NOTE:  The table of Deflators is available as Table 1.1.9., "Implicit Price Deflators for Gross Domestic Product", in the National Income and Product Account Tables, published by U.S. Department of Commerce, Bureau of Economic Analysis, National Economic Accounts, available on-line at the following web address:  www.bea.gov/national/nipaweb/TableView.asp? SelectedTable=13&FirstYear=2002&LastYear=2004&Freq=Qtr.

 

c)         During the active life of the facility, the owner or operator must revise the closure cost estimate no later than 30 days after a revision has been made to the closure plan that increases the cost of closure. If the owner or operator has an approved closure plan, the closure cost estimate must be revised no later than 30 days after the Agency has approved the request to modify the closure plan if the change in the closure plan increases the cost of closure.  The revised closure cost estimate must be adjusted for inflation as specified in subsection (b).

 

d)         The owner or operator must keep the following at the facility during the operating life of the facility: the latest closure cost estimate prepared in accordance with subsections (a) and (c), and, when this estimate has been adjusted in accordance with subsection (b), the latest adjusted closure cost estimate.

Section 725.243  Financial Assurance for Closure

 

An owner or operator of each facility must establish financial assurance for closure of the facility.  The owner or operator must choose from the options specified in subsections (a) through (e).

 

a)         Closure Trust Fund

 

1)         An owner or operator may satisfy the requirements of this Section by establishing a closure trust fund that conforms to the requirements of this subsection and submitting an original, signed duplicate of the trust agreement to the Agency.  The trustee must be an entity that has the authority to act as a trustee and whose trust operations are regulated and examined by a federal or State agency.

 

2)         The wording of the trust agreement must be as specified in 35 Ill. Adm. Code 724.251, and the trust agreement must be accompanied by a formal certification of acknowledgment, as specified in 35 Ill. Adm. Code 724.251.  Schedule A of the trust agreement must be updated within 60 days after a change in the amount of the current closure cost estimate covered by the agreement.

 

3)         Payments into the trust fund must be made annually by the owner or operator over the remaining operating life of the facility as estimated in the closure plan; this period is hereafter referred to as the "pay-in period". The payments into the closure trust fund must be made as follows:

 

A)        The first payment must be at least equal to the current closure cost estimate, except as provided in subsection (f), divided by the number of years in the pay-in period.

 

B)        Subsequent payments must be made no later than 30 days after each anniversary date of the first payment. The amount of each subsequent payment must be determined by this formula:  

 

Next Payment	=	(CE-CV)
		Y

 

Where:

 

CE	=	the current closure cost estimate
CV	=	the current value of the trust fund
Y	=	the number of years remaining in the pay-in period

 

4)         The owner or operator may accelerate payments into the trust fund or may deposit the full amount of the current closure cost estimate at the time the fund is established.  However, the owner or operator must maintain the value of the fund at no less than the value that the fund would have if annual payments were made as specified in subsection (a)(3).

 

5)         If the owner or operator establishes a closure trust fund after having used one or more alternate mechanisms specified in this Section, the owner or operator's first payment must be in at least the amount that the fund would contain if the trust fund were established initially and annual payments made as specified in subsection (a)(3).

 

6)         After the pay-in period is completed, whenever the current closure cost estimate changes, the owner or operator must compare the new estimate with the trustee's most recent annual valuation of the trust fund.  If the value of the fund is less than the amount of the new estimate, the owner or operator, within 60 days after the change in the cost estimate, must either deposit an amount into the fund so that its value after this deposit at least equals the amount of the current closure cost estimate, or obtain other financial assurance, as specified in this Section, to cover the difference.

 

7)         If the value of the trust fund is greater than the total amount of the current closure cost estimate, the owner or operator may submit a written request to the Agency for release of the amount in excess of the current closure cost estimate.

 

8)         If an owner or operator substitutes other financial assurance, as specified in this Section, for all or part of the trust fund, the owner or operator may submit a written request to the Agency for release of the amount in excess of the current closure cost estimate covered by the trust fund.

 

9)         Within 60 days after receiving a request from the owner or operator for release of funds as specified in subsection (a)(7) or (a)(8), the Agency must instruct the trustee to release to the owner or operator such funds as the Agency specifies in writing.

 

10)         After beginning partial or final closure, an owner or operator or another person authorized to conduct partial or final closure may request reimbursement for closure expenditures by submitting itemized bills to the Agency. The owner or operator may request reimbursement for partial closure only if sufficient funds are remaining in the trust fund to cover the maximum costs of closing the facility over its remaining operating life.  Within 60 days after receiving bills for partial or final closure activities, the Agency must instruct the trustee to make reimbursement in those amounts as the Agency specifies in writing if the Agency determines that the partial or final closure expenditures are in accordance with the approved closure plan, or otherwise justified.  If the Agency determines that the maximum cost of closure over the remaining life of the facility will be significantly greater than the value of the trust fund, it must withhold reimbursement of such amounts as it deems prudent until it determines, in accordance with subsection (h), that the owner or operator is no longer required to maintain financial assurance for final closure of the facility. If the Agency does not instruct the trustee to make such reimbursements, the Agency must provide the owner or operator a detailed written statement of reasons.

 

11)         The Agency must agree to termination of the trust when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

b)         Surety Bond Guaranteeing Payment into a Closure Trust Fund

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining a surety bond that conforms to the requirements of this subsection (b) and submitting the bond to the Agency.  The surety company issuing the bond must, at a minimum, be among those listed as acceptable sureties on federal bonds in Circular 570 of the U.S. Department of the Treasury.

 

BOARD NOTE:  The U.S. Department of the Treasury updates Circular 570, "Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies", on an annual basis pursuant to 31 CFR 223.16.  Circular 570 is available on the Internet from the following website:  http://www.fms.treas.gov/c570/.

 

2)         The wording of the surety bond must be as specified in 35 Ill. Adm. Code 724.251.

 

3)         The owner or operator that uses a surety bond to satisfy the requirements of this Section must also establish a standby trust fund.  Under the terms of the bond, all payments made thereunder will be deposited by the surety directly into the standby trust fund in accordance with instructions from the Agency.  This standby trust fund must meet the requirements specified in subsection (a), except as follows:

 

A)        An original, signed duplicate of the trust agreement must be submitted to the Agency with the surety bond; and

 

B)        Until the standby trust fund is funded pursuant to the requirements of this Section, the following are not required by these regulations:

 

i)          Payments into the trust fund, as specified in subsection (a);

 

ii)         Updating of Schedule A of the trust agreement (see 35 Ill. Adm. Code 724.251(a)) to show current closure cost estimates;

 

iii)        Annual valuations, as required by the trust agreement; and

 

iv)        Notices of nonpayment, as required by the trust agreement.

 

4)         The bond must guarantee that the owner or operator will:

 

A)        Fund the standby trust fund in an amount equal to the penal sum of the bond before the beginning of final closure of the facility;

 

B)        Fund the standby trust fund in an amount equal to the penal sum within 15 days after an order to begin final closure is issued by the Board or a court of competent jurisdiction; or

 

C)        Provide alternate financial assurance, as specified in this Section, and obtain the Agency's written approval of the assurance provided, within 90 days after receipt by both the owner or operator and the Agency of a notice of cancellation of the bond from the surety.

 

5)         Under the terms of the bond, the surety will become liable on the bond obligation when the owner or operator fails to perform as guaranteed by the bond.

 

6)         The penal sum of the bond must be in an amount at least equal to the current closure cost estimate, except as provided in subsection (f).

 

7)         Whenever the current closure cost estimate increases to an amount greater than the penal sum, the owner or operator, within 60 days after the increase, must either cause the penal sum to be increased to an amount at least equal to the current closure cost estimate and submit evidence of such increase to the Agency, or obtain other financial assurance, as specified in this Section, to cover the increase.  Whenever the current closure cost estimate decreases, the penal sum may be reduced to the amount of the current closure cost estimate following written approval by the Agency.

 

8)         Under the terms of the bond, the surety may cancel the bond by sending notice of cancellation by certified mail to the owner or operator and to the Agency.  Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Agency, as evidenced by the return receipts.

 

9)         The owner or operator may cancel the bond if the Agency has given prior written consent based on its receipt of evidence of alternate financial assurance, as specified in this Section.

 

c)         Closure Letter of Credit

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining an irrevocable standby letter of credit that conforms to the requirements of this subsection (c) and submitting the letter to the Agency.  The issuing institution must be an entity that has the authority to issue letters of credit and whose letter-of-credit operations are regulated and examined by a federal or State agency.

 

2)         The wording of the letter of credit must be as specified in 35 Ill. Adm. Code 724.251.

 

3)         An owner or operator that uses a letter of credit to satisfy the requirements of this Section must also establish a standby trust fund.  Under the terms of the letter of credit, all amounts paid pursuant to a draft by the Agency must be deposited by the issuing institution directly into the standby trust fund in accordance with instructions from the Agency.  This standby trust fund must meet the requirements of the trust fund specified in subsection (a), except as follows:

 

A)        An original, signed duplicate of the trust agreement must be submitted to the Agency with the letter of credit; and

 

B)        Unless the standby trust fund is funded pursuant to the requirements of this Section, the following are not required by these regulations:

 

i)          Payments into the trust fund, as specified in subsection (a);

 

ii)         Updating of Schedule A of the trust agreement (as specified in 35 Ill. Adm. Code 724.251) to show current closure cost estimates;

 

iii)        Annual valuations, as required by the trust agreement; and

 

iv)        Notices of nonpayment as required by the trust agreement.

 

4)         The letter of credit must be accompanied by a letter from the owner or operator referring to the letter of credit by number, issuing institution, and date and providing the following information: the USEPA identification number, name, and address of the facility, and the amount of funds assured for closure of the facility by the letter of credit.

 

5)         The letter of credit must be irrevocable and issued for a period of at least one year.  The letter of credit must provide that the expiration date will be automatically extended for a period of at least one year unless, at least 120 days before the current expiration date, the issuing institution notifies both the owner or operator and the Agency by certified mail of a decision not to extend the expiration date.  Under the terms of the letter of credit, the 120 days will begin on the date when both the owner or operator and the Agency have received the notice, as evidenced by the return receipts.

 

6)         The letter of credit must be issued in an amount at least equal to the current closure cost estimate, except as provided in subsection (f).

 

7)         Whenever the current closure cost estimate increases to an amount greater than the amount of the credit, the owner or operator, within 60 days after the increase, must either cause the amount of the credit to be increased so that it at least equals the current closure cost estimate and submit evidence of such increase to the Agency, or obtain other financial assurance, as specified in this Section, to cover the increase.  Whenever the current closure cost estimate decreases, the amount of the credit may be reduced to the amount of the current closure cost estimate following written approval by the Agency.

 

8)         Following a final judicial determination or Board order finding that the owner or operator has failed to perform final closure in accordance with the approved closure plan when required to do so, the Agency may draw on the letter of credit.

 

9)         If the owner or operator does not establish alternate financial assurance, as specified in this Section, and obtain written approval of such alternate assurance from the Agency within 90 days after receipt by both the owner or operator and the Agency of a notice from issuing institution that it has decided not to extend the letter of credit beyond the current expiration date, the Agency must draw on the letter of credit.  The Agency may delay the drawing if the issuing institution grants an extension of the term of the credit.  During the last 30 days of any such extension the Agency must draw on the letter of credit if the owner or operator has failed to provide alternate financial assurance, as specified in this Section, and obtain written approval of such assurance from the Agency.

 

10)         The Agency must return the letter of credit to the issuing institution for termination when one of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

d)         Closure Insurance

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining closure insurance that conforms to the requirements of this subsection and submitting a certificate of such insurance to the Agency.  At a minimum, the insurer must be licensed to transact the business of insurance, or eligible to provide insurance as an excess or surplus lines insurer, in one or more States.

 

2)         The wording of the certificate of insurance must be as specified in 35 Ill. Adm. Code 724.251.

 

3)         The closure insurance policy must be issued for a face amount at least equal to the current closure cost estimate, except as provided in subsection (f).  The term "face amount" means the total amount the insurer is obligated to pay under the policy.  Actual payments by the insurer will not change the face amount, although the insurer's future liability will be lowered by the amount of the payments.

 

4)         The closure insurance policy must guarantee that funds will be available to close the facility whenever final closure occurs.  The policy must also guarantee that, once final closure begins, the insurer will be responsible for paying out funds, up to an amount equal to the face amount of the policy, upon the direction of the Agency to such party or parties as the Agency specifies.

 

5)         After beginning partial or final closure, an owner or operator or any other person authorized to conduct closure may request reimbursement for closure expenditures by submitting itemized bills to the Agency.  The owner or operator may request reimbursement for partial closure only if the remaining value of the policy is sufficient to cover the maximum costs of closing the facility over its remaining operating life.  Within 60 days after receiving bills for closure activities, the Agency must instruct the insurer to make reimbursement in such amounts as the Agency specifies in writing if the Agency determines that the partial or final closure expenditures are in accordance with the approved closure plan or otherwise justified.  If the Agency determines that the maximum cost of closure over the remaining life of the facility will be significantly greater than the face amount of the policy, it must withhold reimbursement of such amounts as it deems prudent until it determines, in accordance with subsection (h), that the owner or operator is no longer required to maintain financial assurance for final closure of the particular facility.  If the Agency does not instruct the insurer to make such reimbursements, the Agency must provide the owner or operator with a detailed written statement of reasons.

 

6)         The owner or operator must maintain the policy in full force and effect until the Agency consents to termination of the policy by the owner or operator as specified in subsection (d)(10).  Failure to pay the premium, without substitution of alternate financial assurance as specified in this Section, will constitute a significant violation of these regulations, warranting such remedy as the Board may impose pursuant to the Environmental Protection Act.  Such violation will be deemed to begin upon receipt by the Agency of a notice of future cancellation, termination, or failure to renew due to nonpayment of the premium, rather than upon the date of expiration.

 

7)         Each policy must contain a provision allowing assignment of the policy to a successor owner or operator.  Such assignment may be conditional upon consent of the insurer, provided such consent is not unreasonably refused.

 

8)         The policy must provide that the insurer may not cancel, terminate, or fail to renew the policy except for failure to pay the premium.  The automatic renewal of the policy must, at a minimum, provide the insured with the option of renewal at the face amount of the expiring policy.  If there is a failure to pay the premium, the insurer may elect to cancel, terminate, or fail to renew the policy by sending notice by certified mail to the owner or operator and the Agency.  Cancellation, termination, or failure to renew may not occur, however, during the 120 days beginning with the date of receipt of the notice by both the Agency and the owner or operator, as evidenced by the return receipts.  Cancellation, termination, or failure to renew may not occur and the policy will remain in full force and effect in the event that, on or before the date of expiration, one of the following occurs:

 

A)        The Agency deems the facility abandoned;

 

B)        Interim status is terminated or revoked;

 

C)        Closure is ordered by the Board or a court of competent jurisdiction;

 

D)        The owner or operator is named as debtor in a voluntary or involuntary proceeding under 11 USC (Bankruptcy); or

 

E)        The premium due is paid.

 

9)         Whenever the current closure cost estimate increases to an amount greater than the face amount of the policy, the owner or operator, within 60 days after the increase, must either cause the face amount to be increased to an amount at least equal to the current closure cost estimate and submit evidence of such increase to the Agency, or obtain other financial assurance as specified in this Section to cover the increase.  Whenever the current closure cost estimate decreases, the face amount may be reduced to the amount of the current closure cost estimate following written approval by the Agency.

 

10)         The Agency must give written consent to the owner or operator that the owner or operator may terminate the insurance policy when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

e)         Financial Test and Corporate Guarantee for Closure

 

1)         An owner or operator may satisfy the requirements of this Section by demonstrating that the owner or operator passes a financial test as specified in this subsection. To pass this test the owner or operator must meet the criteria of either subsection (e)(1)(A) or (e)(1)(B):

 

A)        The owner or operator must have all of the following:

 

i)          Two of the following three ratios:  a ratio of total liabilities to net worth less than 2.0; a ratio of the sum of net income plus depreciation, depletion and amortization to total liabilities greater than 0.1; and a ratio of current assets to current liabilities greater than 1.5;

 

ii)         Net working capital and tangible net worth each at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates;

 

iii)        Tangible net worth of at least $10 million; and

 

iv)        Assets located in the United States amounting to at least 90 percent of total assets or at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates.

 

B)        The owner or operator must have all of the following:

 

i)          A current rating for its most recent bond issuance of AAA, AA, A, or BBB, as issued by Standard and Poor's, or Aaa, Aa, A, or Baa, as issued by Moody's;

 

ii)         Tangible net worth at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates;

 

iii)        Tangible net worth of at least $10 million; and

 

iv)        Assets located in the United States amounting to at least 90 percent of total assets or at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates.

 

2)         The phrase "current closure and post-closure cost estimates", as used in subsection (e)(1), refers to the cost estimates required to be shown in subsections 1 through 4 of the letter from the owner's or operator's chief financial officer (see 35 Ill. Adm. Code 724.251).  The phrase "current plugging and abandonment cost estimates", as used in subsection (e)(1), refers to the cost estimates required to be shown in subsections 1 through 4 of the letter from the owner's or operator's chief financial officer (see 35 Ill. Adm. Code 704.240).

 

3)         To demonstrate that the owner or operator meets this test, the owner or operator must submit each of the following items to the Agency:

 

A)        A letter signed by the owner's or operator's chief financial officer and worded as specified in 35 Ill. Adm. Code 724.251;

 

B)        A copy of the independent certified public accountant's report on examination of the owner's or operator's financial statements for the latest completed fiscal year; and

 

C)        A special report from the owner's or operator's independent certified public accountant to the owner or operator stating the following:

 

i)          That the accountant has compared the data that the letter from the chief financial officer specifies as having been derived from the independently audited, year-end financial statements for the latest fiscal year with the amounts in such financial statements; and

 

ii)         In connection with that procedure, that no matters came to the accountant's attention which caused the accountant to believe that the specified data should be adjusted.

 

4)         This subsection (e)(4) corresponds with 40 CFR 265.143(e)(4), a federal provision relating to an extension of the time to file the proofs of financial assurance required by this subsection (e) granted by USEPA.  This statement maintains structural consistency with the corresponding federal regulations.

 

5)         After the initial submission of items specified in subsection (e)(3), the owner or operator must send updated information to the Agency within 90 days after the close of each succeeding fiscal year.  This information must consist of all three items specified in subsection (e)(3).

 

6)         If the owner or operator no longer meets the requirements of subsection (e)(1), the owner or operator must send notice to the Agency of intent to establish alternate financial assurance as specified in this Section.  The notice must be sent by certified mail within 90 days after the end of the fiscal year for which the year-end financial data show that the owner or operator no longer meets the requirements.  The owner or operator must provide the alternate financial assurance within 120 days after the end of such fiscal year.

 

7)         The Agency may, based on a reasonable belief that the owner or operator may no longer meet the requirements of subsection (e)(1), require reports of financial condition at any time from the owner or operator in addition to those specified in subsection (e)(3).  If the Agency finds, on the basis of such reports or other information, that the owner or operator no longer meets the requirements of subsection (e)(1), the owner or operator must provide alternate financial assurance as specified in this Section within 30 days after notification of such a finding.

 

8)         The Agency may disallow use of this test on the basis of qualifications in the opinion expressed by the independent certified public accountant in the accountant's report on examination of the owner's or operator's financial statements (see subsection (e)(3)(B)).  An adverse opinion or a disclaimer of opinion will be cause for disallowance. The Agency must evaluate other qualifications on an individual basis.  The owner or operator must provide alternate financial assurance as specified in this Section within 30 days after notification of the disallowance.

 

9)         The owner or operator is no longer required to submit the items specified in subsection (e)(3) when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

10)         An owner or operator may meet the requirements of this Section by obtaining a written guarantee, hereafter referred to as "corporate guarantee".  The guarantor must be the direct or higher-tier parent corporation of the owner or operator, a firm whose parent corporation is also the parent corporation of the owner or operator, or a firm with a "substantial business relationship" with the owner or operator.  The guarantor must meet the requirements for owners or operators in subsections (e)(1) through (e)(8), and must comply with the terms of the corporate guarantee. The wording of the corporate guarantee must be identical to the wording specified in 35 Ill. Adm. Code 724.251.  The corporate guarantee must accompany the items sent to the Agency as specified in subsection (e)(3).  One of these items must be the letter from the guarantor's chief financial officer.  If the guarantor's parent corporation is also the parent corporation of the owner or operator, the letter must describe the value received in consideration of the guarantee.  If the guarantor is a firm with a "substantial business relationship" with the owner or operator, this letter must describe this substantial business relationship" and the value received in consideration of the guarantee. The terms of the corporate guarantee must provide the following:

 

A)        That, if the owner or operator fails to perform final closure of a facility covered by the corporate guarantee in accordance with the closure plan and other interim status requirements whenever required to do so, the guarantor will do so or establish a trust fund as specified in subsection (a), in the name of the owner or operator.

 

B)        That the corporate guarantee will remain in force unless the guarantor sends notice of cancellation by certified mail to the owner or operator and to the Agency.  Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Agency, as evidenced by the return receipts.

 

C)        That, if the owner or operator fails to provide alternate financial assurance as specified in this Section and obtain the written approval of such alternate assurance from the Agency within 90 days after receipt by both the owner or operator and the Agency of a notice of cancellation of the corporate guarantee from the guarantor, the guarantor will provide such alternate financial assurance in the name of the owner or operator.

 

f)         Use of Multiple Financial Mechanisms.  An owner or operator may satisfy the requirements of this Section by establishing more than one financial mechanism per facility.  These mechanisms are limited to trust funds, surety bonds, letters of credit, and insurance.  The mechanisms must be as specified in subsections (a) through (d), respectively, except that it is the combination of mechanisms, rather than the single mechanism, that must provide financial assurance for an amount at least equal to the current closure cost estimate.  If an owner or operator uses a trust fund in combination with a surety bond or a letter of credit, the owner or operator may use the trust fund as the standby trust fund for the other mechanisms.  A single standby trust fund may be established for two or more mechanisms.  The Agency may use any or all of the mechanisms to provide for closure of the facility.

 

g)         Use of a Financial Mechanism for Multiple Facilities. An owner or operator may use a financial assurance mechanism specified in this Section to meet the requirements of this Section for more than one facility.  Evidence of financial assurance submitted to the Agency must include a list showing, for each facility, the USEPA identification number, name, address, and the amount of funds for closure assured by the mechanism.  The amount of funds available through the mechanism must be no less than the sum of funds that would be available if a separate mechanism had been established and maintained for each facility.  The amount of funds available to the Agency must be sufficient to close all of the owner or operator's facilities.  In directing funds available through the mechanism for closure of any of the facilities covered by the mechanism, the Agency may direct only the amount of funds designated for that facility, unless the owner or operator agrees to the use of additional funds available under the mechanism.

 

h)         Release of the Owner or Operator from the Requirements of This Section.  Within 60 days after receiving certifications from the owner or operator and a qualified Professional Engineer that final closure has been completed in accordance with the approved closure plan, the Agency must notify the owner or operator in writing that the owner or operator is no longer required by this Section to maintain financial assurance for closure of the facility, unless the Agency determines that closure has not been in accordance with the approved closure plan.  The Agency must provide the owner or operator a detailed written statement of any such determination that closure has not been in accordance with the approved closure plan.

 

i)          Appeal.  The following Agency actions are deemed to be permit modifications or refusals to modify for purposes of appeal to the Board (35 Ill. Adm. Code 702.184(e)(3)):

 

1)         An increase in, or a refusal to decrease the amount of, a bond, letter of credit, or insurance; or

 

2)         Requiring alternate assurance upon a finding that an owner or operator or parent corporation no longer meets a financial test.

Section 725.244  Cost Estimate for Post-Closure Care

 

a)         The owner or operator of a hazardous waste disposal unit must have a detailed written estimate, in current dollars, of the annual cost of post-closure monitoring and maintenance of the facility in accordance with the applicable post-closure regulations in Section 725.217 through 725.220, 725.328, 725.358, 725.380, and 725.410.

 

1)         The post-closure cost estimate must be based on the costs to the owner or operator of hiring a third party to conduct post-closure care activities.  A third party is a party that is neither a parent nor a subsidiary of the owner or operator.  (See the definition of "parent corporation" in Section 725.241(d).)

 

2)         The post-closure cost estimate is calculated by multiplying the annual post-closure cost estimate by the number of years of post-closure care required under Section 725.217.

 

b)         During the active life of the facility, the owner or operator must adjust the post-closure cost estimate for inflation within 30 days after each anniversary of the date on which the first post-closure cost estimate was prepared.  The adjustment must be made 60 days prior to the anniversary date of the establishment of the financial instruments used to comply with Section 725.245.  For an owner or operator using the financial test or corporate guarantee, the closure cost estimate must be updated for inflation within 30 days after the close of the firm's fiscal year and before submission of updated information to the Agency as specified in Section 725.245(e)(5).  The adjustment may be made by recalculating the post-closure cost estimate in current dollars, or by using an inflation factor derived from the annual Implicit Price Deflator for Gross National Product as published by the U.S. Department of Commerce in its Survey of Current Business as specified in subsections (b)(1) and (b)(2).  The inflation factor is the result of dividing the latest published annual Deflator by the Deflator for the previous year.

 

1)         The first adjustment is made by multiplying the post-closure estimate by the inflation factor.  The result is the adjusted post-closure cost estimate.

 

2)         Subsequent adjustments are made by multiplying the latest adjusted post-closure cost estimate by the latest inflation factor.

 

c)         During the active life of the facility, the owner or operator must revise the post-closure cost estimate whenever a change in the post-closure plan no later than 30 days after a revision to the post-closure plan that increases the cost of post-closure care.  If the owner or operator has an approved post-closure plan, the post-closure cost estimate must be revised no later than 30 days after the Agency has approved the request to modify the plan if the change in the post-closure plan increases the cost of post-closure care.  The revised post-closure cost estimate must be adjusted for inflation as specified in subsection (b).

 

d)         The owner or operator must keep the following at the facility during the operating life of the facility: the latest post-closure cost estimate prepared in accordance with subsections (a) and (c) and, when this estimate has been adjusted in accordance with subsection (b), the latest adjusted post-closure cost estimate.

Section 725.245  Financial Assurance for Post-Closure Monitoring and Maintenance

 

An owner or operator of a facility with a hazardous waste disposal unit must establish financial assurance for post-closure care of the disposal units.  The owner or operator must choose from the following options:

 

a)         Post-Closure Trust Fund

 

1)         An owner or operator may satisfy the requirements of this Section by establishing a post-closure trust fund that conforms to the requirements of this subsection and submitting an original, signed duplicate of the trust agreement to the Agency.  The trustee must be an entity that has the authority to act as a trustee and whose trust operations are regulated and examined by a federal or State agency.

 

2)         The wording of the trust agreement must be as specified in 35 Ill. Adm. Code 724.251 and the trust agreement must be accompanied by a formal certification of acknowledgment (as specified in 35 Ill. Adm. Code 724.251).  Schedule A of the trust agreement must be updated within 60 days after a change in the amount of the current post-closure cost estimate covered by the agreement.

 

3)         Payments into the trust fund must be made annually by the owner or operator over the remaining operating life of the facility as estimated in the closure plan; this period is hereafter referred to as the "pay-in period". The payments into the post-closure trust fund must be made as follows:

 

A)        The first payment must be at least equal to the current post-closure cost estimate, except as provided in subsection (f), divided by the number of years in the pay-in period.

 

B)        Subsequent payments must be made no later than 30 days after each anniversary date of the first payment. The amount of each subsequent payment must be determined by this formula:

 

Next Payment	=	(CE-CV)
		Y

 

Where:

 

CE	=	the current closure cost estimate
CV	=	the current value of the trust fund
Y	=	the number of years remaining in the pay-in period

 

4)         The owner or operator may accelerate payments into the trust fund or may deposit the full amount of the current post-closure cost estimate at the time the fund is established.  However, the owner or operator must maintain the value of the fund at no less than the value that the fund would have if annual payments were made as specified in subsection (a)(3).

 

5)         If the owner or operator establishes a post-closure trust fund after having used one or more alternate mechanisms specified in this Section, the owner or operator's first payment must be in at least the amount that the fund would contain if the trust fund were established initially and annual payments made as specified in subsection (a)(3).

 

6)         After the pay-in period is completed, whenever the current post-closure cost estimate changes during the operating life of the facility, the owner or operator must compare the new estimate with the trustee's most recent annual valuation of the trust fund.  If the value of the fund is less than the amount of the new estimate, the owner or operator, within 60 days after the change in the cost estimate, must either deposit an amount into the fund so that its value after this deposit at least equals the amount of the current post-closure cost estimate, or obtain other financial assurance as specified in this Section to cover the difference.

 

7)         During the operating life of the facility, if the value of the trust fund is greater than the total amount of the current post-closure cost estimate, the owner or operator may submit a written request to the Agency for release of the amount in excess of the current post-closure cost estimate.

 

8)         If an owner or operator substitutes other financial assurance as specified in this Section for all or part of the trust fund, owner or operator may submit a written request to the Agency for release of the amount in excess of the current post-closure cost estimate covered by the trust fund.

 

9)         Within 60 days after receiving a request from the owner or operator for release of funds as specified in subsection (a)(7) or (a)(8), the Agency must instruct the trustee to release to the owner or operator such funds as the Agency specifies in writing.

 

10)         During the period of post-closure care, the Agency must approve a release of funds if the owner or operator demonstrates to the Agency that the value of the trust fund exceeds the remaining cost of post-closure care.

 

11)         An owner or operator or any other person authorized to perform post-closure care may request reimbursement for post-closure care expenditures by submitting itemized bills to the Agency.  Within 60 days after receiving bills for post-closure activities, the Agency must instruct the trustee to make reimbursement in those amounts as the Agency specifies in writing if the Agency determines that the post-closure care expenditures are in accordance with the approved post-closure plan or otherwise justified. If the Agency does not instruct the trustee to make such reimbursements, the Agency must provide the owner or operator with a detailed written statement of reasons.

 

12)         The Agency must agree to termination of a trust when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

b)         Surety Bond Guaranteeing Payment into a Post-Closure Trust Fund

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining a surety bond that conforms to the requirements of this subsection (b) and submitting the bond to the Agency.  The surety company issuing the bond must, at a minimum, be among those listed as acceptable sureties on federal bonds in Circular 570 of the U.S. Department of the Treasury.

 

BOARD NOTE:  The U.S. Department of the Treasury updates Circular 570, "Companies Holding Certificates of Authority as Acceptable Sureties on Federal Bonds and as Acceptable Reinsuring Companies", on an annual basis pursuant to 31 CFR 223.16. Circular 570 is available on the Internet from the following website:  http://www.fms.treas.gov/c570/.

 

2)         The wording of the surety bond must be as specified in 35 Ill. Adm. Code 724.251.

 

3)         The owner or operator that uses a surety bond to satisfy the requirements of this Section must also establish a standby trust fund.  Under the terms of the bond, all payments made thereunder will be deposited by the surety directly into the standby trust fund in accordance with instructions from the Agency.  This standby trust fund must meet the requirements specified in subsection (a), except as follows:

 

A)        An original, signed duplicate of the trust agreement must be submitted to the Agency with the surety bond; and

 

B)        Until the standby trust fund is funded pursuant to the requirements of this Section, the following are not required by these regulations:

 

i)          Payments into the trust fund, as specified in subsection (a);

 

ii)         Updating of Schedule A of the trust agreement (as specified in 35 Ill. Adm. Code 724.251) to show current post-closure cost estimates;

 

iii)        Annual valuations, as required by the trust agreement; and

 

iv)        Notices of nonpayment, as required by the trust agreement.

 

4)         The bond must guarantee that the owner or operator will perform the following acts:

 

A)        Fund the standby trust fund in an amount equal to the penal sum of the bond before the beginning of final closure of the facility; or

 

B)        Fund the standby trust fund in an amount equal to the penal sum within 15 days after an order to begin closure is issued by the Board or a court of competent jurisdiction; or

 

C)        Provide alternate financial assurance, as specified in this Section, and obtain the Agency's written approval of the assurance provided, within 90 days after receipt by both the owner or operator and the Agency of a notice of cancellation of the bond from the surety.

 

5)         Under the terms of the bond, the surety will become liable on the bond obligation when the owner or operator fails to perform as guaranteed by the bond.

 

6)         The penal sum of the bond must be in an amount at least equal to the current post-closure cost estimate, except as provided in subsection (f).

 

7)         Whenever the current post-closure cost estimate increases to an amount greater than the penal sum, the owner or operator, within 60 days after the increase, must either cause the penal sum to be increased to an amount at least equal to the current post-closure cost estimate and submit evidence of such increase to the Agency or obtain other financial assurance as specified in this Section to cover the increase.  Whenever the current post-closure cost estimate decreases, the penal sum may be reduced to the amount of the current post-closure cost estimate following written approval by the Agency.

 

8)         Under the terms of the bond, the surety may cancel the bond by sending notice of cancellation by certified mail to the owner or operator and to the Agency.  Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Agency, as evidenced by the return receipts.

 

9)         The owner or operator may cancel the bond if the Agency has given prior written consent based on its receipt of evidence of alternate financial assurance as specified in this Section.

 

c)         Post-Closure Letter of Credit

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining an irrevocable standby letter of credit that conforms to the requirements of this subsection (c) and submitting the letter to the Agency.  The issuing institution must be an entity that has the authority to issue letters of credit and whose letter-of-credit operations are regulated and examined by a federal or State agency.

 

2)         The wording of the letter of credit must be as specified in 35 Ill. Adm. Code 724.251.

 

3)         An owner or operator that uses a letter of credit to satisfy the requirements of this Section must also establish a standby trust fund.  Under the terms of the letter of credit, all amounts paid pursuant to a draft by the Agency must be deposited by the issuing institution directly into the standby trust fund in accordance with instructions from the Agency.  This standby trust fund must meet the requirements of the trust fund specified in subsection (a), except as follows:

 

A)        An original, signed duplicate of the trust agreement must be submitted to the Agency with the letter of credit; and

 

B)        Unless the standby trust fund is funded pursuant to the requirements of this Section, the following are not required by these regulations:

 

i)          Payments into the trust fund, as specified in subsection (a);

 

ii)         Updating of Schedule A of the trust agreement (as specified in 35 Ill. Adm. Code 724.151) to show current post-closure cost estimates;

 

iii)        Annual valuations, as required by the trust agreement; and

 

iv)        Notices of nonpayment, as required by the trust agreement.

 

4)         The letter of credit must be accompanied by a letter from the owner or operator referring to the letter of credit by number, issuing institution, and date and providing the following information: the USEPA identification number, name, and address of the facility, and the amount of funds assured for post-closure care of the facility by the letter of credit.

 

5)         The letter of credit must be irrevocable and issued for a period of at least one year.  The letter of credit must provide that the expiration date will be automatically extended for a period of at least one year unless, at least 120 days before the current expiration date, the issuing institution notifies both the owner or operator and the Agency by certified mail of a decision not to extend the expiration date.  Under the terms of the letter of credit, the 120 days will begin on the date when both the owner or operator and the Agency have received the notice, as evidenced by the return receipts.

 

6)         The letter of credit must be issued in an amount at least equal to the current post-closure cost estimate, except as provided in subsection (f).

 

7)         Whenever the current post-closure cost estimate increases to an amount greater than the amount of the credit during the operating life of the facility, the owner or operator, within 60 days after the increase, must either cause the amount of the credit to be increased so that it at least equals the current post-closure cost estimate and submit evidence of such increase to the Agency, or obtain other financial assurance, as specified in this Section, to cover the increase.  Whenever the current cost estimate decreases during the operating life of the facility, the amount of the credit may be reduced to the amount of the current post-closure cost estimate following written approval by the Agency.

 

8)         During the period of post-closure care, the Agency must approve a decrease in the amount of the letter of credit if the owner or operator demonstrates to the Agency that the amount exceeds the remaining cost of post-closure care.

 

9)         Following a final judicial determination or Board order finding that the owner or operator has failed to perform post-closure care in accordance with the approved post-closure plan and other interim status requirements, the Agency may draw on the letter of credit.

 

10)         If the owner or operator does not establish alternate financial assurance, as specified in this Section, and obtain written approval of such alternate assurance from the Agency within 90 days after receipt by both the owner or operator and the Agency of a notice from the issuing institution that it has decided not to extend the letter of credit beyond the current expiration date, the Agency must draw on the letter of credit.  The Agency may delay the drawing if the issuing institution grants an extension of the term of the credit.  During the last 30 days after any such extension the Agency must draw on the letter of credit if the owner or operator has failed to provide alternate financial assurance, as specified in this Section, and obtain written approval of such assurance from the Agency.

 

11)         The Agency must return the letter of credit to the issuing institution for termination when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

d)         Post-Closure Insurance

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining post-closure insurance that conforms to the requirements of this subsection and submitting a certificate of such insurance to the Agency.  At a minimum, the insurer must be licensed to transact the business of insurance, or eligible to provide insurance as an excess or surplus lines insurer, in one or more states.

 

2)         The wording of the certificate of insurance must be as specified in 35 Ill. Adm. Code 724.251.

 

3)         The post-closure insurance policy must be issued for a face amount at least equal to the current post-closure estimate, except as provided in subsection (f).  The term "face amount" means the total amount the insurer is obligated to pay under the policy.  Actual payments by the insurer will not change the face amount, although the insurer's future liability will be lowered by the amount of the payments.

 

4)         The post-closure insurance policy must guarantee that funds will be available to provide post-closure care of facility whenever the post-closure period begins. The policy must also guarantee that, once post-closure care begins, the insurer will be responsible for paying out funds, up to an amount equal to the face amount of the policy, upon the direction of the Agency, to such party or parties as the Agency specifies.

 

5)         An owner or operator or any other person authorized to perform post-closure care may request reimbursement for post-closure care expenditures by submitting itemized bills to the Agency.  Within 60 days after receiving bills for post-closure activities, the Agency must instruct the insurer to make reimbursement in such amounts as the Agency specifies in writing, if the Agency determines that the post-closure care expenditures are in accordance with the approved post-closure plan or otherwise justified.  If the Agency does not instruct the insurer to make such reimbursements, the Agency must provide the owner or operator with a detailed written statement of reasons.

 

6)         The owner or operator must maintain the policy in full force and effect until the Agency consents to termination of the policy by the owner or operator, as specified in subsection (d)(11).  Failure to pay the premium, without substitution of alternate financial assurance, as specified in this Section, will constitute a significant violation of these regulations, warranting such remedy as the Board may impose pursuant to the Environmental Protection Act.  Such violation will be deemed to begin upon receipt by the Agency of a notice of future cancellation, termination, or failure to renew due to nonpayment of the premium, rather than upon the date of expiration.

 

7)         Each policy must contain a provision allowing assignment of the policy to a successor owner or operator.  Such assignment may be conditional upon consent of the insurer, provided such consent is not unreasonably refused.

 

8)         The policy must provide that the insurer may not cancel, terminate, or fail to renew the policy except for failure to pay the premium.  The automatic renewal of the policy must, at a minimum, provide the insured with the option of renewal at the face amount of the expiring policy.  If there is a failure to pay the premium, the insurer may elect to cancel, terminate, or fail to renew the policy by sending notice by certified mail to the owner or operator and the Agency.  Cancellation, termination, or failure to renew may not occur, however, during the 120 days beginning with the date of receipt of the notice by both the Agency and the owner or operator, as evidenced by the return receipts.  Cancellation, termination, or failure to renew may not occur, and the policy will remain in full force and effect in the event that, on or before the date of expiration, one of the following occurs:

 

A)        The Agency deems the facility abandoned;

 

B)        Interim status is terminated or revoked;

 

C)        Closure is ordered by the Board or a court of competent jurisdiction;

 

D)        The owner or operator is named as debtor in a voluntary or involuntary proceeding under 11 USC (Bankruptcy); or

 

E)        The premium due is paid.

 

9)         Whenever the current post-closure cost estimate increases to an amount greater than the face amount of the policy during the operating life of the facility, the owner or operator, within 60 days after the increase, must either cause the face amount to be increased to an amount at least equal to the current post-closure cost estimate and submit evidence of such increase to the Agency, or obtain other financial assurance, as specified in this Section, to cover the increase.  Whenever the current post-closure cost estimate decreases during the operating life of the facility, the face amount may be reduced to the amount of the current post-closure cost estimate following written approval by the Agency.

 

10)         Commencing on the date that liability to make payments pursuant to the policy accrues, the insurer must thereafter annually increase the face amount of the policy.  Such increase must be equivalent to the face amount of the policy, less any payments made, multiplied by an amount equivalent to 85 percent of the most recent investment rate or of the equivalent coupon-issue yield announced by the U.S. Treasury for 26-week Treasury securities.

 

11)         The Agency must give written consent to the owner or operator that the owner or operator may terminate the insurance policy when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

e)         Financial Test and Corporate Guarantee for Post-Closure Care

 

1)         An owner or operator may satisfy the requirements of this Section by demonstrating that the owner or operator passes a financial test, as specified in this subsection (e).  To pass this test the owner or operator must meet the criteria of either subsection (e)(1)(A) or (e)(1)(B):

 

A)        The owner or operator must have each of the following:

 

i)          Two of the following three ratios:  a ratio of total liabilities to net worth less than 2.0; a ratio of the sum of net income plus depreciation, depletion and amortization to total liabilities greater than 0.1; and a ratio of current assets to current liabilities greater than 1.5;

 

ii)         Net working capital and tangible net worth each at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates;

 

iii)        Tangible new worth of at least $10 million; and

 

iv)        Assets in the United States amounting to at least 90 percent of total assets or at least six times the sum of the current closure and post-closure cost estimates and the plugging and abandonment cost estimates.

 

B)        The owner or operator must have each of the following:

 

i)          A current rating for its most recent bond issuance of AAA, AA, A, or BBB, as issued by Standard and Poor's, or Aaa, Aa, A, or Baa, as issued by Moody's;

 

ii)         Tangible net worth at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates;

 

iii)        Tangible net worth of at least $10 million; and

 

iv)        Assets located in the United States amounting to at least 90 percent of its total assets or at least six times the sum of the current closure and post-closure cost estimates and the current plugging and abandonment cost estimates.

 

2)         The phrase "current closure and post-closure cost estimates", as used in subsection (e)(1), refers to the cost estimates required to be shown in subsections 1 through 4 of the letter from the owner's or operator's chief financial officer (see 35 Ill. Adm. Code 724.251).  The phrases "current plugging and abandonment cost estimates", as used in subsection (e)(1), refers to the cost estimates required to be shown in subsections 1 through 4 of the letter from the owner's or operator's chief financial officer (see 35 Ill. Adm. Code 704.240).

 

3)         To demonstrate that it meets this test, the owner or operator must submit each of the following items to the Agency:

 

A)        A letter signed by the owner's or operator's chief financial officer and worded as specified in 35 Ill. Adm. Code 724.251;

 

B)        A copy of the independent certified public accountant's report on examination of the owner's or operator's financial statements for the latest completed fiscal year; and

 

C)        A special report from the owner's or operator's independent certified public accountant to the owner or operator stating both of the following:

 

i)          That the accountant has compared the data that the letter from the chief financial officer specifies as having been derived from the independently audited, year-end financial statements for the latest fiscal year with the amounts in such financial statements; and

 

ii)         In connection with that procedure, that no matters came to the accountant's attention that caused the accountant to believe that the specified data should be adjusted.

 

4)         This subsection (e)(4) corresponds with 40 CFR 265.143(e)(4), a federal provision relating to an extension of the time to file the proofs of financial assurance required by this subsection (e) granted by USEPA.  This statement maintains structural consistency with the corresponding federal regulations.

 

5)         After the initial submission of items specified in subsection (e)(3), the owner or operator must send updated information to the Agency within 90 days after the close of each succeeding fiscal year.  This information must consist of all three items specified in subsection (e)(3).

 

6)         If the owner or operator no longer meets the requirements of subsection (e)(1), the owner or operator must send notice to the Agency of intent to establish alternate financial assurance, as specified in this Section.  The notice must be sent by certified mail within 90 days after the end of the fiscal year for which the year-end financial data show that the owner or operator no longer meets the requirements.  The owner or operator must provide the alternate financial assurance within 120 days after the end of such fiscal year.

 

7)         The Agency may, based on a reasonable belief that the owner or operator may no longer meet the requirements of subsection (e)(1), require reports of financial condition at any time from the owner or operator in addition to those specified in subsection (e)(3).  If the Agency finds, on the basis of such reports or other information, that the owner or operator no longer meets the requirements of subsection (e)(1), the owner or operator must provide alternate financial assurance, as specified in this Section, within 30 days after notification of such a finding.

 

8)         The Agency may disallow use of this test on the basis of qualifications in the opinion expressed by the independent certified public accountant in the accountant's report on examination of the owner's or operator's financial statements (see subsection (e)(3)(B)).  An adverse opinion or a disclaimer of opinion will be cause for disallowance. The Agency must evaluate other qualifications on an individual basis.  The owner or operator must provide alternate financial assurance, as specified in this Section, within 30 days after notification of the disallowance.

 

9)         During the period of post-closure care, the Agency must approve a decrease in the current post-closure cost estimate for which this test demonstrates financial assurance if the owner or operator demonstrates to the Agency that the amount of the cost estimate exceeds the remaining cost of post-closure care.

 

10)         The owner or operator is no longer required to submit the items specified in subsection (e)(3) when either of the following occurs:

 

A)        An owner or operator substitutes alternate financial assurance, as specified in this Section; or

 

B)        The Agency releases the owner or operator from the requirements of this Section in accordance with subsection (h).

 

11)         An owner or operator may meet the requirements of this Section by obtaining a written guarantee, hereafter referred to as "corporate guarantee".  The guarantor must be the direct or higher-tier parent corporation of the owner or operator, a firm whose parent corporation is also the parent corporation of the owner or operator, or a firm with a "substantial business relationship" with the owner or operator.  The guarantor must meet the requirements for owners or operators in subsections (e)(1) through (e)(9), and must comply with the terms of the corporate guarantee.  The wording of the corporate guarantee must be identical to the wording specified in 35 Ill. Adm. Code 724.251. The corporate guarantee must accompany the items sent to the Agency as specified in subsection (e)(3).  One of these items must be the letter from the guarantor's chief financial officer.  If the guarantor's parent corporation is also the parent corporation of the owner or operator, the letter must describe the value received in consideration of the guarantee.  If the guarantor is a firm with a "substantial business relationship" with the owner or operator, this letter must describe this substantial business relationship" and the value received in consideration of the guarantee.  The terms of the corporate guarantee must provide as follows:

 

A)        That, if the owner or operator fails to perform post-closure care of a facility covered by the corporate guarantee in accordance with the post-closure plan and other interim status requirements whenever required to do so, the guarantor will do so or establish a trust fund as specified in subsection (a), in the name of the owner or operator.

 

B)        That the corporate guarantee will remain in force unless the guarantor sends notice of cancellation by certified mail to the owner or operator and to the Agency.  Cancellation may not occur, however, during the 120 days beginning on the date of receipt of the notice of cancellation by both the owner or operator and the Agency, as evidenced by the return receipts.

 

C)        That, if the owner or operator fails to provide alternate financial assurance, as specified in this Section, and obtain the written approval of such alternate assurance from the Agency within 90 days after receipt by both the owner or operator and the Agency of a notice of cancellation of the corporate guarantee from the guarantor, the guarantor will provide such alternate financial assurance in the name of the owner or operator.

 

f)         Use of Multiple Financial Mechanisms.  An owner or operator may satisfy the requirements of this Section by establishing more than one financial mechanism per facility.  These mechanisms are limited to trust funds, surety bonds, letters of credit, and insurance.  The mechanisms must be as specified in subsections (a) through (d), respectively, except that it is the combination of mechanisms, rather than the single mechanism, that must provide financial assurance for an amount at least equal to the current post-closure cost estimate.  If an owner or operator uses a trust fund in combination with a surety bond or a letter of credit, it may use the trust fund as the standby trust fund for the other mechanisms.  A single standby trust fund may be established for two or more mechanisms.  The Agency may use any or all of the mechanisms to provide for post-closure care of the facility.

 

g)         Use of a Financial Mechanism for Multiple Facilities. An owner or operator may use a financial assurance mechanism specified in this Section to meet the requirements of this Section for more than one facility. Evidence of financial assurance submitted to the Agency must include a list showing, for each facility, the USEPA Identification Number, name, address, and the amount of funds for post-closure care assured by the mechanism.  The amount of funds available through the mechanism must be no less than the sum of funds that would be available if a separate mechanism had been established and maintained for each facility.  The amount of funds available to the Agency must be sufficient to provide post-closure care for all of the owner or operator's facilities.  In directing funds available through the mechanism for post-closure care of any of the facilities covered by the mechanism, the Agency may direct only the amount of funds designated for that facility, unless the owner or operator agrees to the use of additional funds available under the mechanism.

 

h)         Release of the Owner or Operator from the Requirements of This Section.  Within 60 days after receiving certifications from the owner or operator and a qualified Professional Engineer that the post-closure care period has been completed in accordance with the approved post-closure plan, the Agency must notify the owner or operator in writing that the owner or operator is no longer required by this Section to maintain financial assurance for post-closure care of that unit, unless the Agency determines that post-closure care has not been in accordance with the approved plan.  The Agency must provide the owner or operator a detailed written statement of any such determination that post-closure care has not been in accordance with the approved post-closure plan.

 

i)          Appeal.  The following Agency actions are deemed to be permit modifications or refusals to modify for purposes of appeal to the Board (35 Ill. Adm. Code 702.184(e)(3)):

 

1)         An increase in, or a refusal to decrease the amount of, a bond, letter of credit, or insurance; or

 

2)         Requiring alternate assurance upon a finding that an owner or operator or parent corporation no longer meets a financial test.

Section 725.246  Use of a Mechanism for Financial Assurance of Both Closure and Post-Closure Care

 

An owner or operator may satisfy the requirements for financial assurance for both closure and post-closure care for one or more facilities by using a trust fund, surety bond, letter of credit, insurance, financial test, or corporate guarantee that meets the specifications for the mechanism in both Sections 725.243 and 725.245.  The amount of funds available through the mechanism must be no less than the sum of funds that would be available if a separate mechanism had been established and maintained for financial assurance of closure and of post-closure care.

If the owner or operator demonstrates the required coverage through the use of a combination of financial assurances pursuant to this subsection (a)(6), the owner or operator must specify at least one such assurance as "primary" coverage, and must specify other such assurance as "excess" coverage.

 

7)         An owner or operator must notify the Agency within 30 days whenever one of the following occurs:

B)        A Certification of Valid Claim for bodily injury or property damages caused by sudden or non-sudden accidental occurrence arising from the operation of a hazardous waste treatment, storage, or disposal facility is entered between the owner or operator and third-party claimant for liability coverage pursuant to subsections (a)(1) through (a)(6); or

 

C)        A final court order establishing a judgment for bodily injury or property damage caused by a sudden or non-sudden accidental occurrence arising from the operation of a hazardous waste treatment, storage, or disposal facility is issued against the owner or operator or an instrument that is providing financial assurance for liability coverage pursuant to subsections (a)(1) through (a)(6).

 

b)         Coverage for Nonsudden Accidental Occurrences.  An owner or operator of a surface impoundment, landfill, or land treatment facility that is used to manage hazardous waste, or a group of such facilities, must demonstrate financial responsibility for bodily injury and property damage to third parties caused by nonsudden accidental occurrences arising from operations of the facility or group of facilities.  The owner or operator must have and maintain liability coverage for nonsudden accidental occurrences in the amount of at least $3 million per occurrence with an annual aggregate of at least $6 million, exclusive of legal defense costs.  An owner or operator meeting the requirements of this Section may combine the required per-occurrence coverage levels for sudden and nonsudden accidental occurrences into a single per-occurrence level, and combine the required annual aggregate coverage levels for sudden and nonsudden accidental occurrences into a single annual aggregate level.  An owner or operator that combines coverage levels for sudden and nonsudden accidental occurrences must maintain liability coverage in the amount of at least $4 million per occurrence and $8 million annual aggregate.  This liability coverage may be demonstrated, as specified in subsections (b)(1) through (b)(6):

 

1)         An owner or operator may demonstrate the required liability coverage by having liability insurance, as specified in this subsection (b)(1).

 

A)        Each insurance policy must be amended by attachment of the Hazardous Waste Facility Liability Endorsement or evidenced by a Certificate of Liability Insurance.  The wording of the endorsement must be as specified in 35 Ill. Adm. Code 724.251.  The wording of the certificate of insurance must be as specified in 35 Ill. Adm. Code 724.251.  The owner or operator must submit a signed duplicate original of the endorsement or the certificate of insurance to the Agency.  If requested by the Agency, the owner or operator must provide a signed duplicate original of the insurance policy.

 

B)        Each insurance policy must be issued by an insurer that is licensed by the Illinois Department of Financial and Professional Regulation, Division of Insurance.

4)         An owner or operator may meet the requirements of this Section by obtaining a surety bond for liability coverage, as specified in subsection (i).

 

5)         An owner or operator may meet the requirements of this Section by obtaining a trust fund for liability coverage, as specified in subsection (j).

 

6)         An owner or operator may demonstrate the required liability coverage through the use of combinations of insurance, financial test, guarantee, letter of credit, surety bond, and trust fund, except that the owner or operator may not combine a financial test covering part of the liability coverage requirement with a guarantee unless the financial statement of the owner or operator is not consolidated with the financial statement of the guarantor.  The amounts of coverage demonstrated must total at least the minimum amounts required by this Section.  If the owner or operator demonstrates the required coverage through the use of a combination of financial assurances pursuant to this subsection (b)(6), the owner or operator must specify at least one such assurance as "primary" coverage, and must specify other such assurance as "excess" coverage.

 

7)         An owner or operator must notify the Agency within 30 days whenever one of the following occurs:

 

A)        A claim results in a reduction in the amount of financial assurance for liability coverage provided by a financial instrument authorized in subsections (b)(1) through (b)(6);

 

B)        A Certification of Valid Claim for bodily injury or property damages caused by sudden or non-sudden accidental occurrence arising from the operation of a hazardous waste treatment, storage, or disposal facility is entered between the owner or operator and third-party claimant for liability coverage pursuant to subsections (b)(1) through (b)(6); or

 

C)        A final court order establishing a judgment for bodily injury or property damage caused by a sudden or non-sudden accidental occurrence arising from the operation of a hazardous waste treatment, storage, or disposal facility is issued against the owner or operator or an instrument that is providing financial assurance for liability coverage pursuant to subsections (b)(1) through (b)(6).

 

c)         Request for Adjusted Level of Required Liability Coverage.  If an owner or operator demonstrates to the Agency that the levels of financial responsibility required by subsection (a) or (b) are not consistent with the degree and duration of risk associated with treatment, storage, or disposal at the facility or group of facilities, the owner or operator may obtain an adjusted level of required liability coverage from the Agency.  The request for an adjusted level of required liability coverage must be submitted in writing to the Agency.  If granted, the Agency's action must take the form of an adjusted level of required liability coverage, such level to be based on the Agency assessment of the degree and duration of risk associated with the ownership or operation of the facility or group of facilities.  The Agency may require an owner or operator that requests an adjusted level of required liability coverage to provide such technical and engineering information as is necessary to determine a level of financial responsibility other than that required by subsection (a) or (b).  The Agency must process any request for an adjusted level of required liability coverage as if it were a permit modification request pursuant to 35 Ill. Adm. Code 703.271(e)(3) and 705.128.  Notwithstanding any other provision, the Agency must hold a public hearing whenever it finds, on the basis of requests, a significant degree of public interest in a tentative decision to grant an adjusted level of required liability insurance.  The Agency may also hold a public hearing at its discretion whenever such a hearing might clarify one or more issues involved in the tentative decision.

 

d)         Adjustments by the Agency.  If the Agency determines that the levels of financial responsibility required by subsection (a) or (b) are not consistent with the degree and duration of risk associated with treatment, storage, or disposal at the facility or group of facilities, the Agency must adjust the level of financial responsibility required pursuant to subsection (a) or (b) as may be necessary to adequately protect human health and the environment.  This adjusted level must be based on the Agency's assessment of the degree and duration of risk associated with the ownership or operation of the facility or group of facilities.  In addition, if the Agency determines that there is a significant risk to human health and the environment from non-sudden accidental occurrences resulting from the operations of a facility that is not a surface impoundment, landfill or land treatment facility, the Agency may require that an owner or operator of the facility comply with subsection (b).  An owner or operator must furnish to the Agency, within a time specified by the Agency in the request, which must not be less than 30 days, any information that the Agency requests to determine whether cause exists for such adjustments of level or type of coverage.  The Agency must process any request for an adjusted level of required liability coverage as if it were a permit modification request pursuant to 35 Ill. Adm. Code 703.271(e)(3) and 705.128.  Notwithstanding any other provision, the Agency must hold a public hearing whenever it finds, on the basis of requests, a significant degree of public interest in a tentative decision to grant an adjusted level of required liability insurance.  The Agency may also hold a public hearing at its discretion whenever such a hearing might clarify one or more issues involved in the tentative decision.

 

e)         Period of Coverage.  Within 60 days after receiving certifications from the owner or operator and a qualified Professional Engineer that final closure has been completed in accordance with the approved closure plan, the Agency must notify the owner or operator in writing that the owner or operator is no longer required by this Section to maintain liability coverage for that facility, unless the Agency determines that closure has not been in accordance with the approved closure plan.

 

f)         Financial Test for Liability Coverage

 

1)         An owner or operator may satisfy the requirements of this Section by demonstrating that the owner or operator passes a financial test, as specified in this subsection (f)(1).  To pass this test the owner or operator must meet the criteria of subsection (f)(1)(A) or (f)(1)(B):

 

A)        The owner or operator must have each of the following:

 

i)          Net working capital and tangible net worth each at least six times the amount of liability coverage to be demonstrated by this test;

 

ii)         Tangible net worth of at least $10 million; and

 

iii)        Assets in the United States amounting to either:  at least 90 percent of total assets; or at least six times the amount of liability coverage to be demonstrated by this test.

 

B)        The owner or operator must have each of the following:

 

i)          A current rating for the owner or operator's most recent bond issuance of AAA, AA, A, or BBB, as issued by Standard and Poor's, or Aaa, Aa, A, or Baa, as issued by Moody's; 

 

ii)         Tangible net worth of at least $10 million;

 

iii)        Tangible net worth at least six times the amount of liability coverage to be demonstrated by this test; and

 

iv)        Assets in the United States amounting to either of the following:  at least 90 percent of total assets or at least six times the amount of liability coverage to be demonstrated by this test.

 

2)         The phrase "amount of liability coverage", as used in subsection (f)(1), refers to the annual aggregate amounts for which coverage is required pursuant to subsections (a) and (b).

 

3)         To demonstrate that the owner or operator meets this test, the owner or operator must submit each of the following three items to the Agency:

 

A)        A letter signed by the owner's or operator's chief financial officer and worded as specified in 35 Ill. Adm. Code 724.251.  If an owner or operator is using the financial test to demonstrate both assurance for closure or post-closure care, as specified by 35 Ill. Adm. Code 724.243(f) and 724.245(f), or by Sections 725.243(e) and 725.245(e), and liability coverage, it must submit the letter specified in 35 Ill. Adm. Code 724.251 to cover both forms of financial responsibility; a separate letter, as specified in 35 Ill. Adm. Code 724.251 is not required.

 

B)        A copy of the independent certified public accountant's report on examination of the owner's or operator's financial statements for the latest completed fiscal year.

 

C)        A special report from the owner's or operator's independent certified public accountant to the owner or operator stating as follows:

 

i)          That the accountant has compared the data that the letter from the chief financial officer specifies as having been derived from the independently audited, year-end financial statements for the latest fiscal year with the amounts in such financial statements; and

 

ii)         In connection with that procedure, that no matters came to the accountant's attention that caused the accountant to believe that the specified data should be adjusted.

 

5)         After the initial submission of items specified in subsection (f)(3), the owner or operator must send updated information to the Agency within 90 days after the close of each succeeding fiscal year.  This information must consist of all three items specified in subsection (f)(3).

 

6)         If the owner or operator no longer meets the requirements of subsection (f)(1), the owner or operator must obtain insurance, a letter of credit, a surety bond, a trust fund, or a guarantee for the entire amount of required liability coverage, as specified in this Section.  Evidence of insurance must be submitted to the Agency within 90 days after the end of the fiscal year for which the year-end financial data show that the owner or operator no longer meets the test requirements.

 

7)         The Agency may disallow use of this test on the basis of qualifications in the opinion expressed by the independent certified public accountant in the accountant's report on examination of the owner's or operator's financial statements (see subsection (f)(3)(B)).  An adverse opinion or a disclaimer of opinion is cause for disallowance.  The Agency must evaluate other qualifications on an individual basis.  The owner or operator must provide evidence of insurance for the entire amount of required liability coverage, as specified in this Section, within 30 days after notification of disallowance.

 

g)         Guarantee for Liability Coverage

 

1)         Subject to subsection (g)(2), an owner or operator may meet the requirements of this Section by obtaining a written guarantee, referred to as a "guarantee".  The guarantor must be the direct or higher-tier parent corporation of the owner or operator, a firm whose parent corporation is also the parent corporation of the owner or operator, or a firm with a "substantial business relationship" with the owner or operator.  The guarantor must meet the requirements for owners and operators in subsections (f)(1) through (f)(6).  The wording of the guarantee must be as specified in 35 Ill. Adm. Code 724.251.  A certified copy of the guarantee must accompany the items sent to the Agency as specified in subsection (f)(3).  One of these items must be the letter from the guarantor's chief financial officer.  If the guarantor's parent corporation is also the parent corporation of the owner or operator, this letter must describe the value received in consideration of the guarantee.  If the guarantor is a firm with a "substantial business relationship" with the owner or operator, this letter must describe this "substantial business relationship" and the value received in consideration of the guarantee.  The terms of the guarantee must provide as follows:

 

A)        If the owner or operator fails to satisfy a judgment based on a determination of liability for bodily injury or property damage to third parties caused by sudden or nonsudden accidental occurrences (or both as the case may be), arising from the operation of facilities covered by this guarantee, or fails to pay an amount agreed to in settlement of claims arising from or alleged to arise from such injury or damage, the guarantor will do so up to the limits of coverage.

 

B)        The guarantee remains in force unless the guarantor sends notice of cancellation by certified mail to the owner or operator and to the Agency.  The guarantee must not be terminated unless and until the Agency approves alternate liability coverage complying with Section 725.247 or 35 Ill. Adm. Code 724.247.

 

2)         The guarantor must execute the guarantee in Illinois.  The guarantee must be accompanied by a letter signed by the guarantor that states as follows:

 

A)        The guarantee was signed in Illinois by an authorized agent of the guarantor;

 

B)        The guarantee is governed by Illinois law; and

 

C)        The name and address of the guarantor's registered agent for service of process.

 

3)         The guarantor must have a registered agent pursuant to Section 5.05 of the Business Corporation Act of 1983 [805 ILCS 5/5.05] or Section 105.05 of the General Not-for-Profit Corporation Act of 1986 [805 ILCS 105/105.05].

 

h)         Letter of Credit for Liability Coverage

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining an irrevocable standby letter of credit that conforms to the requirements of this subsection, and submitting a copy of the letter of credit to the Agency.

 

2)         The financial institution issuing the letter of credit must be an entity that has the authority to issue letters of credit and whose letter of credit operations are regulated and examined by the Illinois Commissioner of Banks and Trust Companies.

 

3)         The wording of the letter of credit must be as specified in 35 Ill. Adm. Code 724.251.

 

4)         An owner or operator that uses a letter of credit to satisfy the requirements of this Section may also establish a trust fund.  Under the terms of such a letter of credit, all amounts paid pursuant to a draft by the trustee of the standby trust will be deposited by the issuing institution into the standby trust in accordance with instructions from the trustee.  The trustee of the standby trust fund must be an entity that has the authority to act as a trustee and whose trust operations are regulated and examined by the Illinois Commissioner of Banks and Trust Companies, or that complies with the Corporate Fiduciary Act [205 ILCS 620].

 

5)         The wording of the standby trust fund must be identical to the wording specified in 35 Ill. Adm. Code 724.251(n).

 

i)          Surety Bond for Liability Coverage

 

1)         An owner or operator may satisfy the requirements of this Section by obtaining a surety bond that conforms to the requirements of this subsection (i) and submitting a copy of the bond to the Agency.

 

2)         The surety company issuing the bond must be licensed by the Illinois Department of Financial and Professional Regulation, Division of Insurance.

 

3)         The wording of the surety bond must be as specified in 35 Ill. Adm. Code 724.251.

 

j)          Trust Fund for Liability Coverage

 

1)         An owner or operator may satisfy the requirements of this Section by establishing a trust fund that conforms to the requirements of this subsection and submitting a signed, duplicate original of the trust agreement to the Agency.

 

2)         The trustee must be an entity that has the authority to act as a trustee and whose trust operations are regulated and examined by the Illinois Commissioner of Banks and Trust Companies, or that complies with the Corporate Fiduciary Act [205 ILCS 620].

 

3)         The trust fund for liability coverage must be funded for the full amount of the liability coverage to be provided by the trust fund before it may be relied upon to satisfy the requirements of this Section. If at any time after the trust fund is created the amount of funds in the trust fund is reduced below the full amount of liability coverage to be provided, the owner or operator, by the anniversary of the date of establishment of the fund, must either add sufficient funds to the trust fund to cause its value to equal the full amount of liability coverage to be provided, or obtain other financial assurance, as specified in this Section, to cover the difference. For purposes of this subsection, "the full amount of the liability coverage to be provided" means the amount of coverage for sudden and nonsudden accidental occurrences required to be provided by the owner or operator by this Section, less the amount of financial assurance for liability coverage that is being provided by other financial assurance mechanisms being used to demonstrate financial assurance by the owner or operator.

 

4)         The wording of the trust fund must be as specified in 35 Ill. Adm. Code 724.251.

Section 725.248  Incapacity of Owners or Operators, Guarantors, or Financial Institutions

 

a)         An owner or operator must notify the Agency by certified mail of the commencement of a voluntary or involuntary proceeding under 11 USC (Bankruptcy) naming the owner or operator as debtor, within 10 days after commencement of the proceeding.  A guarantor of a corporate guarantee as specified in Sections 725.243(e) and 725.245(e) must make such a notification if the guarantor is named as a debtor, as required under the terms of the corporate guarantee (see 35 Ill. Adm. Code 724.251).

 

b)         An owner or operator that fulfills the requirements of Sections 725.243, 725.245 or 725.247 by obtaining a trust fund, surety bond, letter of credit, or insurance policy will be deemed to be without the required financial assurance or liability coverage in the event of bankruptcy of the trustee or issuing institution, or a suspension or revocation of the authority of the trustee institution to act as trustee or of the institution issuing the surety bond, letter of credit, or insurance policy to issue such instruments.  The owner or operator must establish other financial assurance or liability coverage within 60 days after such an event.

2)         A leak or spill of hazardous waste is exempted from the requirements of this subsection (d) if the following occur:

 

A)        The spill is less than or equal to a quantity of one pound (0.45 kg); and

 

B)        The spill is immediately contained and cleaned-up.

 

3)         Within 30 days after detection of a release to the environment, a report containing the following information must be submitted to the Agency:

 

A)        Likely route of migration of the release;

 

B)        Characteristics of the surrounding soil (soil composition, geology, hydrogeology, climate, etc.);

 

C)        Results of any monitoring or sampling conducted in connection with the release (if available).  If sampling or monitoring data relating to the release are not available within 30 days, these data must be submitted to the Agency as soon as they become available;

 

D)        Proximity to downgradient drinking water, surface water, and population areas; and

 

E)        Description of response actions taken or planned.

 

e)         Provision of Secondary Containment, Repair, or Closure

 

1)         Unless the owner or operator satisfies the requirements of subsections (e)(2) through (e)(4), the tank system must be closed in accordance with Section 725.297.

 

2)         If the cause of the release was a spill that has not damaged the integrity of the system, the owner or operator may return the system to service as soon as the released waste is removed and repairs, if necessary, are made.

 

3)         If the cause of the release was a leak from the primary tank system into the secondary containment system, the system must be repaired prior to returning the tank system to service.

 

4)         If the source of the release was a leak to the environment from a component of a tank system without secondary containment, the owner or operator must provide the component of the system from which the leak occurred with secondary containment that satisfies the requirements of Section 725.293 before it is returned to service, unless the source of the leak is an aboveground portion of a tank system.  If the source is an aboveground component that can be inspected visually, the component must be repaired and may be returned to service without secondary containment as long as the requirements of subsection (f) are satisfied.  If a component is replaced to comply with the requirements of this subsection (e)(4), that component must satisfy the requirements for new tank systems or components in Sections 725.292 and 725.293.  Additionally, if a leak has occurred in any portion of a tank system component that is not readily accessible for visual inspection (e.g., the bottom of an inground or on-ground tank), the entire component must be provided with secondary containment in accordance with Section 725.293 prior to being returned to use.

 

f)         Certification of Major Repairs.  If the owner or operator has repaired a tank system in accordance with subsection (e), and the repair has been extensive (e.g., installation of an internal liner, repair of a ruptured primary containment or secondary containment vessel, etc.), the tank system must not be returned to service unless the owner or operator has obtained a certification by a qualified Professional Engineer, in accordance with 35 Ill. Adm. Code 702.126(d), that the repaired system is capable of handling hazardous wastes without release for the intended life of the system.  This certification must be placed in the operating record and maintained until closure of the facility.

 

BOARD NOTE:  See Section 725.115(c) for the requirements necessary to remedy a failure.  Also, federal 40 CFR 302.6 requires the owner or operator to notify the National Response Center of a release of any "reportable quantity".

Section 725.297  Closure and Post-Closure Care

 

a)         At closure of a tank system, the owner or operator must remove or decontaminate all waste residues, contaminated containment system components (liners, etc.), contaminated soils and structures and equipment contaminated with waste, and manage them as hazardous waste, unless 35 Ill. Adm. Code 721.103(d) applies.  The closure plan, closure activities, cost estimates for closure, and financial responsibility for tank systems must meet all of the requirements specified in Subparts G and H.

 

b)         If the owner or operator demonstrates that not all contaminated soils can be practicably removed or decontaminated as required in subsection (a), then the owner or operator must close the tank system and perform post-closure care in accordance with the closure and post-closure care requirements that apply to landfills (Section 725.410).  In addition, for the purposes of closure, post-closure and financial responsibility, such a tank system is then considered to be a landfill, and the owner or operator must meet all of the requirements of landfills specified in Subparts G and H.

 

c)         If an owner or operator has a tank system that does not have secondary containment that meets the requirements of Section 725.293(b) through (f), and which is not exempt from the secondary containment requirements in accordance with Section 725.293(g), then the following requirements apply:

 

1)         The closure plan for the tank system must include both a plan for complying with subsection (a), and a contingent plan for complying with subsection (b);

 

2)         A contingent post-closure plan for complying with subsection (b) must be prepared and submitted as part of the permit application;

 

3)         The cost estimates calculated for closure and post-closure care must reflect the costs of complying with the contingent closure plan and the contingent post-closure plan, if these costs are greater than the costs of complying with the closure plan prepared for the expected closure under subsection (a);

 

4)         Financial assurance must be based on the cost estimates in subsection (c)(3); and

 

5)         For the purposes of the contingent closure and post-closure plans, such a tank system is considered to be a landfill, and the contingent plans must meet all of the closure, post-closure care, and financial responsibility requirements for landfills under Subparts G and H.

SUBPART K: SURFACE IMPOUNDMENTS

 

Section 725.320  Applicability

 

The regulations in this Subpart K apply to owners and operators of facilities that use surface impoundments to treat, store, or dispose of hazardous waste, except as Section 725.101 provides otherwise.

 

(Source:  Amended at 29 Ill. Reg. 6389, effective April 22, 2005)

 

Section 725.321  Design and Operating Requirements

 

a)         The owner or operator of each new surface impoundment unit, each lateral expansion of a surface impoundment unit, and each replacement of an existing surface impoundment unit must install two or more liners and a leachate collection and removal system between such liners, and operate the leachate collection and removal system, in accordance with 35 Ill. Adm. Code 724.321(c), unless exempted under 35 Ill. Adm. Code 724.321(d), (e), or (f). 

 

b)         The owner or operator of each unit referred to in subsection (a) must notify the Agency at least sixty days prior to receiving waste.  The owner or operator of each facility submitting notice must file a Part B application within six months of the receipt of such notice.

 

c)         The owner or operator of any replacement surface impoundment unit is exempt from subsection (a) if the following conditions are fulfilled:

 

1)         The existing unit was constructed in compliance with the design standards of 35 Ill. Adm. Code 724.321(c), (d), and (e); and

 

BOARD NOTE:  The cited subsections implemented the design standards of sections 3004(o)(1)(A)(i) and (o)(5) of RCRA (42 USC 6924(o)(1)(A)(i) and (o)(5)).

 

2)         There is no reason to believe that the liner is not functioning as designed.

 

d)         The Agency must not require a double liner as set forth in subsection (a) for any monofill, if the following conditions are fulfilled:

 

1)         The monofill contains only hazardous wastes from foundry furnace emission controls or metal casting molding sand, and such wastes do not contain constituents that render the wastes hazardous for reasons other than the toxicity characteristic in 35 Ill. Adm. Code 721.124, with USEPA hazardous waste numbers D004 through D017; and

 

2)         No Migration Demonstration

 

A)        Design and Location Requirements

 

i)          The monofill has at least one liner for which there is no evidence that such liner is leaking.  For the purposes of this subsection (d)(2)(A)(i) the term "liner" means a liner designed, constructed, installed, and operated to prevent hazardous waste from passing into the liner at any time during the active life of the facility, or a liner designed, constructed, installed, and operated to prevent hazardous waste from migrating beyond the liner to adjacent subsurface soil, groundwater, or surface water at any time during the active life of the facility.  In the case of any surface impoundment that has been exempted from the requirements of subsection (a), of a liner designed, constructed, installed, and operated to prevent hazardous waste from passing beyond the liner, at the closure of such impoundment the owner or operator must remove or decontaminate all waste residues, all contaminated liner material and contaminated soil to the extent practicable.  If all contaminated soil is not removed or decontaminated, the owner or operator of such impoundment must comply with appropriate post-closure requirements, including but not limited to groundwater monitoring and corrective action;

 

ii)         The monofill is located more than one-quarter mile from an underground source of drinking water (as that term is defined in 35 Ill. Adm. Code 702.110); and

 

iii)        The monofill is in compliance with generally applicable groundwater monitoring requirements for facilities with RCRA permits; or

 

B)        The owner or operator demonstrates to the Board that the monofill is located, designed, and operated so as to assure that there will be no migration of any hazardous constituent into groundwater or surface water at any future time.

 

e)         In the case of any unit in which the liner and leachate collection system have been installed pursuant to the requirements of subsection (a), and in good faith compliance with subsection (a) and with guidance documents governing liners and leachate collection systems under subsection (a), the Agency must not require a liner or leachate collection system that is different from that which was so installed pursuant to subsection (a) when issuing  the first permit to such facility, except that the Agency is not precluded from requiring installation of a new liner when the Agency finds that any liner installed pursuant to the requirements of subsection (a) is leaking.

 

f)         A surface impoundment must maintain enough freeboard to prevent any overtopping of the dike by overfilling, wave action, or a storm.  Except as provided in subsection (g), there must be at least 60 centimeters (two feet) of freeboard.

 

g)         A freeboard level less than 60 centimeters (two feet) may be maintained if the owner or operator obtains certification by a qualified engineer that alternate design features or operating plans will, to the best of the engineer's knowledge and opinion, prevent overtopping of the dike.  The certification, along with a written identification of alternate design features or operating plans preventing overtopping, must be maintained at the facility.

 

BOARD NOTE:  Any point source discharge from a surface impoundment to waters of the State is subject to the requirements of Section 12 of the Environmental Protection Act.  Spills may be subject to Section 311 of the Clean Water Act (33 USC 1321).

 

h)         Surface impoundments that are newly subject to this Part due to the promulgation of additional listings or characteristics for the identification of hazardous waste must be in compliance with subsections (a), (c), or (d) not later than 48 months after the promulgation of the additional listing or characteristic.  This compliance period must not be cut short as the result of the promulgation of land disposal prohibitions under 35 Ill. Adm. Code 728 or the granting of an extension to the effective date of a prohibition pursuant to 35 Ill. Adm. Code 728.105, within this 48 month period.

 

i)          Refusal to grant an exemption or waiver, or grant with conditions, may be appealed to the Board.

Section 725.322  Action Leakage Rate

 

a)         The owner or operator of surface impoundment units subject to Section 725.321(a) must submit a proposed action leakage rate to the Agency when submitting the notice required under Section 725.321(b).  Within 60 days of receipt of the notification, the Agency must do either of the following: establish an action leakage rate, either as proposed by the owner or operator or modified using the criteria in this Section, or extend the review period for up to 30 days.  If no action is taken by the Agency before the original 60 or extended 90 day review periods, the action leakage rate will be approved as proposed by the owner or operator.

 

b)         The Agency must approve an action leakage rate for surface impoundment units subject to Section 725.321(a).  The action leakage rate is the maximum design flow rate that the leak detection system (LDS) can remove without the fluid head on the bottom liner exceeding one foot.  The action leakage rate must include an adequate safety margin to allow for uncertainties in the design (e.g., slope, hydraulic conductivity, thickness of drainage material, etc.), construction, operation, and location of the LDS; waste and leachate characteristics; the likelihood and amounts of other sources of liquids in the LDS; and proposed response actions (e.g., the action leakage rate must consider decreases in the flow capacity of the system over time resulting from siltation and clogging, rib layover, and creep of synthetic components of the system; overburden pressures; etc.).

 

c)         To determine if the action leakage rate has been exceeded, the owner or operator must convert the weekly or monthly flow rate from the monitoring data obtained under Section 725.326(b) to an average daily flow rate (gallons per acre per day) for each sump.  The average daily flow rate for each sump must be calculated weekly during the active life and closure period and, if the unit is closed in accordance with Section 725.328(a)(2), monthly during the post-closure care period, unless the Agency approves a different frequency pursuant to Section 725.326(b).

 

d)         Final Agency determinations pursuant to this Section are deemed to be permit denials for purposes of appeal to the Board pursuant to Section 40 of the Environmental Protection Act.

Section 725.324  Response Actions

 

a)         The owner or operator of surface impoundment units subject to Section 725.321(a) must develop and keep on site a response action plan.  The response action plan must set forth the actions to be taken if the action leakage rate has been exceeded.  At a minimum, the response action plan must describe the actions specified in subsection (b).

 

b)         If the flow rate into the LDS exceeds the action leakage rate for any sump, the owner or operator must do the following:

 

1)         Notify the Agency in writing of the exceedance within seven days after the determination;

 

2)         Submit a preliminary written assessment to the Agency within 14 days of the determination, as to the amount of liquids; likely sources of liquids; possible location, size, and cause of any leaks; and short-term actions taken and planned;

 

3)         Determine to the extent practicable the location, size, and cause of any leak;

 

4)         Determine whether waste receipt should cease or be curtailed; whether any waste should be removed from the unit for inspection, repairs, or controls; and whether or not the unit should be closed;

 

5)         Determine any other short-term and longer-term actions to be taken to mitigate or stop any leaks; and

 

6)         Within 30 days after the notification that the action leakage rate has been exceeded, submit to the Agency the results of the determinations specified in subsections (b)(3) through (b)(5), the results of actions taken, and actions planned.  Monthly thereafter, as long as the flow rate in the LDS exceeds the action leakage rate, the owner or operator must submit to the Agency a report summarizing the results of any remedial actions taken and actions planned.

 

c)         To make the leak or remediation determinations in subsections (b)(3) through (b)(5), the owner or operator must do either of the following:

 

1)         Perform the following assessments:

 

A)        Assess the source of liquids and amounts of liquids by source;

 

B)        Conduct a fingerprint, hazardous constituent, or other analyses of the liquids in the LDS to identify the source of liquids and possible location of any leaks, and the hazard and mobility of the liquid; and

 

C)        Assess the seriousness of any leaks in terms of potential for escaping into the environment; or

 

2)         Document why such assessments are not needed.

 

d)         Final Agency determinations pursuant to this Section are deemed to be permit denials for purposes of appeal to the Board pursuant to Section 40 of the Environmental Protection Act.

Section 725.325  Waste Analysis and Trial Tests

 

In addition to the waste analyses required by Section 725.113, whenever a surface impoundment is to be used for either of the purposes in subsections (a) and (b), the owner or operator must, before treating the different waste or using the different process, perform either of the required actions listed in subsection (c):

 

a)         Chemically treat a hazardous waste that is substantially different from  waste  previously treated in that impoundment; or

 

b)         Chemically treat hazardous waste with a substantially different process than and previously used in that impoundment.

 

c)          Required Actions

 

1)         The owner or operator must conduct waste analyses and trial treatment tests (e.g., bench scale or pilot plant scale tests); or

 

2)         The owner or operator must obtain written, documented information on similar treatment of similar waste under similar operating conditions, to show that this treatment will comply with Section 725.117(b).

 

BOARD NOTE:  As required by Section 725.113, the waste analyses plan must include analyses needed to comply with Sections 725.329 and 725.330.  As required by Section 725.173, the owner or operator must place the results from each waste analysis and trial test, or the documented information in the operating record of the facility.

 

(Source:  Amended at 42 Ill. Reg. 23725, effective November 19, 2018)

 

Section 725.326  Monitoring and Inspections

 

a)         The owner or operator must inspect the following:

 

1)         The freeboard level at least once each operating day to ensure compliance with Section 725.322; and

 

2)         The surface impoundment, including dikes and vegetation surrounding the dike, at least once a week to detect any leaks, deterioration, or failures in the impoundment.

 

BOARD NOTE:  As required by Section 725.115(c), the owner or operator must remedy any deterioration or malfunction the owner or operator finds.

 

b)         LDS

 

1)         An owner or operator required to have a LDS under Section 725.321(a) must record the amount of liquids removed from each LDS sump at least once each week during the active life and closure period.

 

2)         After the final cover is installed, the amount of liquids removed from each LDS sump must be recorded at least monthly.  If the liquid level in the sump stays below the pump operating level for two consecutive months, the amount of liquids in the sumps must be recorded at least quarterly.  If the liquid level in the sump stays below the pump operating level for two consecutive quarters, the amount of liquids in the sumps must be recorded at least semi-annually.  If at any time during the post-closure care period the pump operating level is exceeded at units on quarterly or semi-annual recording schedules, the owner or operator must return to monthly recording of amounts of liquids removed from each sump until the liquid level again stays below the pump operating level for two consecutive months.

 

3)         "Pump operating level" is a liquid level proposed by the owner or operator and approved by the Agency based on pump activation level, sump dimensions, and level that avoids backup into the drainage layer and minimizes head in the sump.  The timing for submission and approval of the proposed "pump operating level" will be in accordance with Section 725.322(a).

 

c)         Final Agency determinations pursuant to this Section are deemed to be permit denials for purposes of appeal to the Board pursuant to Section 40 of the Environmental Protection Act.

a)         The owner or operator of landfill units subject to Section 725.401(a) must submit a proposed action leakage rate to the Agency when submitting the notice required under Section 725.401(b).  Within 60 days after receipt of the notification, the Agency must establish an action leakage rate, either as proposed by the owner or operator or modified using the criteria in this Section, or extend the review period for up to 30 days.  If no action is taken by the Agency before the original 60 or extended 90 day review periods, the action leakage rate will be approved as proposed by the owner or operator.

 

b)         The Agency must approve an action leakage rate for landfill units subject to Section 725.401(a).  The action leakage rate is the maximum design flow rate that the LDS can remove without the fluid head on the bottom liner exceeding one foot.  The action leakage rate must include an adequate safety margin to allow for uncertainties in the design (e.g., slope, hydraulic conductivity, thickness of drainage material, etc.); construction, operation, and location of the LDS; waste and leachate characteristics, likelihood and amounts of other sources of liquids in the LDS; and proposed response actions (e.g., the action leakage rate must consider decreases in the flow capacity of the system over time resulting from siltation and clogging, rib layover, and creep of synthetic components of the system; overburden pressures; etc.).

 

c)         To determine if the action leakage rate has been exceeded, the owner or operator must convert the weekly or monthly flow rate from the monitoring data obtained under Section 725.404 to an average daily flow rate (gallons per acre per day) for each sump.  The average daily flow rate for each sump must be calculated weekly during the active life and closure period, and monthly during the post-closure care period unless the Agency approves a different period under Section 725.404(b).

 

d)         Final Agency determinations pursuant to this Section are deemed to be permit denials for purposes of appeal to the Board pursuant to Section 40 of the Environmental Protection Act.

Section 725.403  Response Actions

 

a)         The owner or operator of landfill units subject to Section 725.401(a) must develop and keep on site until closure of the facility a response action plan.  The response action plan must set forth the actions to be taken if the action leakage rate has been exceeded.  At a minimum, the response action plan must describe the actions specified in subsection (b).

 

b)         If the flow rate into the LDS exceeds the action leakage rate for any sump, the owner or operator must do each of the following:

 

1)         Notify the Agency in writing of the exceedance within seven days after the determination;

 

2)         Submit a preliminary written assessment to the Agency within 14 days after the determination, as to the amount of liquids; likely sources of liquids; possible location, size, and cause of any leaks; and short-term actions taken and planned;

 

3)         Determine to the extent practicable the location, size, and cause of any leak;

 

4)         Determine whether waste receipt should cease or be curtailed; whether any waste should be removed from the unit for inspection, repairs, or controls; and whether or not the unit should be closed;

 

5)         Determine any other short-term and longer-term actions to be taken to mitigate or stop any leaks; and

 

6)         Within 30 days after the notification that the action leakage rate has been exceeded, submit to the Agency the results of the determinations specified in subsections (b)(3) through (b)(5), the results of actions taken, and actions planned.  Monthly thereafter, as long as the flow rate in the LDS exceeds the action leakage rate, the owner or operator must submit to the Agency a report summarizing the results of any remedial actions taken and actions planned.

 

c)         To make the leak or remediation determinations in subsections (b)(3) through (b)(5), the owner or operator must do either of the following:

 

1)         Perform the following assessments:

 

A)        Assess the source of liquids and amounts of liquids by source;

 

B)        Conduct a fingerprint, hazardous constituent or other analyses of the liquids in the LDS to identify the source of liquids and possible location of any leaks, and the hazard and mobility of the liquid; and

 

C)        Assess the seriousness of any leaks in terms of potential for escaping into the environment; or

 

2)         Document why such assessments are not needed.

 

d)         Final Agency determinations pursuant to this Section are deemed to be permit denials for purposes of appeal to the Board pursuant to Section 40 of the Environmental Protection Act.

Section 725.404  Monitoring and Inspections

 

a)         An owner or operator required to have an LDS under Section 725.401(a) must record the amount of liquids removed from each LDS sump at least once each week during the active life and closure period.

 

b)         After the final cover is installed, the amount of liquids removed from each LDS sump must be recorded at least monthly.  If the liquid level in the sump stays below the pump operating level for two consecutive months, the amount of liquids in the sumps must be recorded at least quarterly.  If the liquid level in the sump stays below the pump operating level for two consecutive quarters, the amount of liquids in the sumps must be recorded at least semi-annually.  If at any time during the post-closure care period the pump operating level is exceeded at units on quarterly or semi-annual recording schedules,  the owner or operator must return to monthly recording of amounts of liquids removed from each sump until the liquid level again stays below the pump operating level for two consecutive months.

 

c)         "Pump operating level" is a liquid level proposed by the owner or operator and approved by the Agency based on pump activation level, sump dimensions and level that avoids backup into the drainage layer and minimizes head in the sump.  The timing for submission and approval of the proposed "pump operating level" will be in accordance with Section 725.402(a).

 

d)         Final Agency determinations pursuant to this Section are deemed to be permit denials for purposes of appeal to the Board pursuant to Section 40 of the Environmental Protection Act.

1)         Except as provided by subsections (b)(2) and (b)(3), the standards of this Part no longer apply when an owner or operator demonstrates compliance with the maximum achievable control technology (MACT) requirements of subpart EEE of 40 CFR 63 (National Emission Standards for Hazardous Air Pollutants from Hazardous Waste Combustors), incorporated by reference in 35 Ill. Adm. Code 720.111(b), by conducting a comprehensive performance test and submitting to the Agency a Notification of Compliance, under 40 CFR 63.1207(j) and 63.1210(d), documenting compliance with the requirements of subpart EEE of 40 CFR 63.

 

2)         The MACT standards of subpart EEE of 40 CFR 63 do not replace the closure requirements of Section 724.451 or the applicable requirements of Subparts A through H, BB, and CC.

 

3)         Section 725.445, generally prohibiting burning of hazardous waste during startup and shutdown, remains in effect if the owner or operator elects to comply with 35 Ill. Adm. Code 703.320(b)(1)(A) to minimize emissions of toxic compounds from startup and shutdown.

 

BOARD NOTE: Operating conditions used to determine effective treatment of hazardous waste remain effective after the owner or operator demonstrates compliance with the standards of subpart EEE of 40 CFR 63. Sections 9.1 and 39.5 of the Environmental Protection Act make the federal MACT standards directly applicable to entities in Illinois and authorize the Agency to issue permits based on the federal standards.

 

c)         An owner or operator of an incinerator that burns hazardous waste is exempt from all of the requirements of this Subpart O, except Section 725.451 (Closure), provided that the owner or operator has documented, in writing, that the waste would not reasonably be expected to contain any of the hazardous constituents listed in Appendix H to 35 Ill. Adm. Code 721 and such documentation is retained at the facility, if the waste to be burned is one of the following:

 

1)         It is listed as a hazardous waste in Subpart D of 35 Ill. Adm. Code 721, solely because it is ignitable (Hazard Code I), corrosive (Hazard Code C), or both;

 

2)         It is listed as a hazardous waste in Subpart D of 35 Ill. Adm. Code 721, solely because it is reactive (Hazard Code R) for characteristics other than those listed in 35 Ill. Adm. Code 721.123(a)(4) and (a)(5), and will not be burned when other hazardous wastes are present in the combustion zone;

 

3)         It is a hazardous waste solely because it possesses the characteristic of ignitability, corrosivity, or both, as determined by the tests for characteristics of hazardous wastes under Subpart C of 35 Ill. Adm. Code 721; or

 

4)         It is a hazardous waste solely because it possesses the reactivity characteristics described by 35 Ill. Adm. Code 721.123(a)(1), (a)(2), (a)(3), (a)(6), (a)(7), or (a)(8) and will not be burned when other hazardous wastes are present in the combustion zone.

Adm. Code 726, if the unit is a boiler or industrial furnace, as defined in 35 Ill. Adm. Code 720.110.

 

(Source:  Amended at 42 Ill. Reg. 23725, effective November 19, 2018)

 

Section 725.473  General Operating Requirements

 

Before adding hazardous waste, the owner or operator must bring his thermal treatment process to steady state (normal) conditions of operation, including steady state operating temperature-using auxiliary fuel or other means, unless the process is a noncontinuous (batch) thermal treatment process which requires a complete thermal cycle to treat a discrete quantity of hazardous waste.

 

(Source:  Amended at 29 Ill. Reg. 6389, effective April 22, 2005)

 

Section 725.475  Waste Analysis

 

In addition to the waste analyses required by Section 725.113, the owner or operator must sufficiently analyze any waste that he has not previously treated in his thermal process to enable him to establish steady state (normal) or other appropriate (for a noncontinuous  process) operating conditions (including waste and auxiliary fuel feed) and to determine the type of pollutants that might  be  emitted.  At minimum, the analysis must determine the following:

 

a)         Heating value of the waste;

 

b)         Halogen content and sulfur content in the waste; and

 

c)         Concentrations in the waste of lead and mercury, unless the owner or operator has written, documented data that show that the element is not present.

 

BOARD NOTE:  As required by Section 725.173, the owner or operator must place the results from  each waste analysis or the documented information in the operating record of the facility.

Section 725.481  Closure

 

At closure, the owner or operator must remove all hazardous waste and hazardous waste residues (including, but not limited to, ash) from the thermal treatment process or equipment.

 

BOARD NOTE:  At closure, as throughout the operating period, unless the owner or operator can demonstrate, in accordance with Section 721.103(c) or (d) that any solid waste removed from his thermal treatment process or equipment is not a hazardous waste, the owner or operator becomes a generator of hazardous waste and must manage it in accordance with all applicable requirements of Parts 722, 723, and 725.

 

(Source:  Amended at 29 Ill. Reg. 6389, effective April 22, 2005)

 

Section 725.482  Open Burning; Waste Explosives

 

Open burning of hazardous waste is prohibited except for the open burning and detonation of waste explosives.  Waste explosives include waste that has the potential to detonate and bulk military propellants that cannot safely be disposed of through other modes of treatment.  Detonation is an explosion in which chemical transformation passes through the material faster than the speed of sound (0.33 kilometers/second at sea level).  Owners or operators choosing to open burn or detonate waste explosives must do so in accordance with the following table and in a manner that does not threaten human health or the environment.

 

Distance From Open Pounds of Waste Explosives or Propellants	Burning or Detonation To the Property of Others
0 to 100	204 meters ( 670 feet)
101 to 1,000	380 meters (1,250 feet)
1,001 to 10,000	530 meters (1,730 feet)
10,001 to 30,000	690 meters (2,260 feet)

Section 725.543  Design and Operating Requirements

 

a)         Drip pads must fulfill the following requirements:

 

1)         It must not be constructed of earthen materials, wood, or asphalt, unless the asphalt is structurally supported;

 

2)         It must be sloped to free-drain to the associated collection system treated wood drippage, rain, other waters, or solutions of drippage and water or other wastes;

 

3)         It must have a curb or berm around the perimeter;

 

4)         In addition, the drip pad must fulfill the following requirements:

 

A)        It must have a hydraulic conductivity of less than or equal to 1 x

10^-7 centimeters per second, e.g., existing concrete drip pads must be sealed, coated, or covered with a surface material with a hydraulic conductivity of less than or equal to 1 x 10^-7 centimeters per second such that the entire surface where drippage occurs or may run across is capable of containing such drippage and mixtures of drippage and precipitation, materials, or other wastes while being routed to an associated collection system.  This surface material must be maintained free of cracks and gaps that could adversely affect its hydraulic conductivity, and the material must be chemically compatible with the preservatives that contact the drip pad.  The requirements of this provision apply only to the existing drip pads and those drip pads for which the owner or operator elects to comply with Section 725.542(b) instead of Section 725.542(a).

 

B)        The owner or operator must obtain and keep on file at the facility a written assessment of the drip pad, reviewed and certified by a qualified Professional Engineer that attests to the results of the evaluation. The assessment must be reviewed, updated, and recertified annually. The evaluation must document the extent to which the drip pad meets the design and operating standards of this Section, except for in subsection (b).

 

5)         It must be of sufficient structural strength and thickness to prevent failure due to physical contact, climatic conditions, the stress of installation, and the stress of daily operations, e.g., variable and moving loads such as vehicle traffic, movement of wood, etc.

 

BOARD NOTE:  In judging the structural integrity requirement of this subsection (a), the Agency should generally consider applicable standards established by professional organizations generally recognized by the industry, including ACI 318-83 (Building Code Requirements for Reinforced Concrete) or ASTM C 94-90 (Standard Specification for Ready-Mixed Concrete), incorporated by reference in 35 Ill. Adm. Code 720.111(a).

 

b)         If an owner or operator elects to comply with Section 725.542(a) instead of Section 725.542(b), the drip pad must have the following features:

 

1)         A synthetic liner installed below the drip pad that is designed, constructed, and installed to prevent leakage from the drip pad into the adjacent subsurface soil or groundwater or surface water at any time during the active life (including the closure period) of the drip pad.  The liner must be constructed of materials that will prevent waste from being absorbed into the liner and to prevent releases into the adjacent subsurface soil or groundwater or surface water during the active life of the facility.  The liner must be constructed as follows:

 

A)        It must be constructed of materials that have appropriate chemical properties and sufficient strength and thickness to prevent failure due to pressure gradients (including static head and external hydrogeologic forces), physical contact with the waste or drip pad leakage to which they are exposed, climatic conditions, the stress of installation, and the stress of daily operation (including stresses from vehicular traffic on the drip pad);

 

B)        It must be placed upon a foundation or base capable of providing support to the liner and resistance to pressure gradients above and below the liner to prevent failure of the liner due to settlement, compression, or uplift; and

 

C)        It must be installed to cover all surrounding earth that could come in contact with the waste or leakage; and

 

2)         A leakage detection system immediately above the liner that is designed, constructed, maintained, and operated to detect leakage from the drip pad.  The leakage detection system must be constructed as follows:

 

A)        It must be constructed of materials that fulfill the following requirements:

 

i)          They are chemically resistant to the waste managed in the drip pad and the leakage that might be generated; and

 

ii)         They are of sufficient strength and thickness to prevent collapse under the pressures exerted by overlaying materials and by any equipment used at the drip pad; and

 

B)        It must be designed and operated to function without clogging through the scheduled closure of the drip pad; and

 

C)        It must be designed so that it will detect the failure of the drip pad or the presence of a release of hazardous waste or accumulated liquid at the earliest practicable time.

 

3)         A leakage collection system immediately above the liner that is designed, constructed, maintained, and operated to collect leakage from the drip pad such that it can be removed from below the drip pad.  The date, time, and quantity of any leakage collected in this system and removed must be documented in the operating log.

 

c)         Drip pads must be maintained such that they remain free of cracks, gaps, corrosion, or other deterioration that could cause hazardous waste to be released from the drip pad.

 

BOARD NOTE:  See subsection (m) for remedial action required if deterioration or leakage is detected.

 

d)         The drip pad and associated collection system must be designed and operated to convey, drain and collect liquid resulting from drippage or precipitation in order to prevent run-off.

 

e)         Unless the drip pad is protected by a structure, as described in Section 725.540(b), the owner or operator must design, construct, operate, and maintain a run-on control system capable of preventing flow onto the drip pad during peak discharge from at least a 24-hour, 25-year storm, unless the system has sufficient excess capacity to contain any run-on that might enter the system.

 

f)         Unless the drip pad is protected by a structure or cover, as described in Section 725.540(b), the owner or operator must design, construct, operate, and maintain a run-off management system to collect and control at least the water volume resulting from a 24-hour, 25-year storm.

 

g)         The drip pad must be evaluated to determine that it meets the requirements of subsections (a) through (f).  The owner or operator must obtain a statement from a qualified, Professional Engineer certifying that the drip pad design meets the requirements of this Section.

 

h)         Drippage and accumulated precipitation must be removed from the associated collection system as necessary to prevent overflow onto the drip pad.

 

i)          The drip pad surface must be cleaned thoroughly at least once every seven days using an appropriate and effective cleaning technique, including but not limited to, rinsing, washing with detergents or other appropriate solvents, or steam cleaning, with residues being properly managed, such that accumulated residues of hazardous waste or other materials are removed as to allow weekly inspections of the entire drip pad surface without interference or hindrance from accumulated residues of hazardous waste or other materials on the drip pad.  The owner or operator must document, in the facility's operating log, the date and time of each cleaning and the cleaning procedure.

 

j)          Drip pads must be operated and maintained in a manner to minimize tracking of hazardous waste or hazardous waste constituents off the drip pad as a result of activities by personnel or equipment.

 

k)         After being removed from the treatment vessel, treated wood from pressure and non-pressure processes must be held on the drip pad until drippage has ceased.  The owner or operator must maintain records sufficient to document that all treated wood is held on the pad, in accordance with this Section, following treatment.

 

l)          Collection and holding units associated with run-on and run-off control systems must be emptied or otherwise managed as soon as possible after storms to maintain design capacity of the system.

 

m)        Throughout the active life of the drip pad, if the owner or operator detects a condition that may have caused or has caused a release of hazardous waste, the condition must be repaired within a reasonably prompt period of time following discovery, in accordance with the following procedures:

 

1)         Upon detection of a condition that may have caused or has caused a release of hazardous waste (e.g., upon detection of leakage in the leak detection system), the owner or operator must perform the following acts:

 

A)        It must enter a record of the discovery in the facility operating log;

 

B)        It must immediately remove from service the portion of the drip pad affected by the condition;

 

C)        It must determine what steps must be taken to repair the drip pad, clean up any leakage from below the drip pad, and establish a schedule for accomplishing the clean up and repairs;

 

D)        Within 24 hours after discovery of the condition, the owner or operator must notify the Agency of the condition and, within 10 working days, provide written notice to the Agency with a description of the steps that will be taken to repair the drip pad and clean up any leakage, and the schedule for accomplishing this work.

 

2)         The Agency must:  review the information submitted; make a determination regarding whether the pad must be removed from service completely or partially until repairs and clean up are complete; and notify the owner or operator of the determination and the underlying rationale in writing.

 

3)         Upon completing all repairs and clean up, the owner or operator must notify the Agency in writing and provide a certification, signed by an independent, qualified, registered professional engineer, that the repairs and clean up have been completed according to the written plan submitted in accordance with subsection (m)(1)(D).

 

n)         The owner or operator must maintain, as part of the facility operating log, documentation of past operating and waste handling practices.  This must include identification of preservative formulations used in the past, a description of drippage management practices and a description of treated wood storage and handling practices.

b)         When a closed-vent system is tested for compliance with no detectable emissions, as required in Section 725.933(k), the test must comply with the following requirements:

 

1)         Monitoring must comply with Reference Method 21 (Determination of Volatile Organic Compound Leaks) in appendix A to 40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b).

 

2)         The detection instrument must meet the performance criteria of Reference Method 21.

 

3)         The instrument must be calibrated before use on each day of its use by the procedures specified in Reference Method 21.

 

4)         Calibration gases must be:

 

A)        Zero air (less than 10 ppm of hydrocarbon in air).

 

B)        A mixture of methane or n-hexane and air at a concentration of approximately, but less than, 10,000 ppm methane or n-hexane.

 

5)         The background level must be determined as set forth in Reference Method 21.

 

6)         The instrument probe must be traversed around all potential leak interfaces as close to the interface as possible, as described in Reference Method 21.

 

7)         The arithmetic difference between the maximum concentration indicated by the instrument and the background level is compared with 500 ppm for determining compliance.

 

c)         Performance tests to determine compliance with Section 725.932(a) and with the total organic compound concentration limit of Section 725.933(c) must comply with the following:

 

1)         Performance tests to determine total organic compound concentrations and mass flow rates entering and exiting control devices must be conducted and data reduced in accordance with the following reference methods and calculation procedures:

 

A)        Reference Method 2 (Determination of Stack Gas Velocity and Volumetric Flow Rate (Type S Pitot Tube)) in appendix A to 40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b), for velocity and volumetric flow rate.

 

B)        Reference Method 18 (Measurement of Gaseous Organic Compound Emissions by Gas Chromatography) or 25A (Determination of Total Gaseous Organic Concentration Using a Flame Ionization Analyzer) in appendix A to 40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b), for organic content. If Reference Method 25A is used, the organic hazardous air pollutant (HAP) used as the calibration gas must be the single HAP that represents the largest percent by volume of the emissions. The use of Reference Method 25A is acceptable if the response from the high-level calibration gas is at least 20 times the standard deviation of the response from the zero calibration gas when the instrument is zeroed on the most sensitive scale.

 

C)        Each performance test must consist of three separate runs, each run conducted for at least 1 hour under the conditions that exist when the hazardous waste management unit is operating at the highest load or capacity level reasonably expected to occur. For the purpose of determining total organic compound concentrations and mass flow rates, the average of results of all runs applies. The average must be computed on a time-weighted basis.

 

D)        Total organic mass flow rates must be determined by the following equation:

 

i)          For a source utilizing Reference Method 18:

 



 

Where:

 

Eh	=	The total organic mass flow rate, kg/h
Q2sd	=	The volumetric flow rate of gases entering or exiting control device, dscm/h, as determined by Reference Method 2
n	=	The number of organic compounds in the vent gas
Ci	=	The organic concentration in ppm, dry basis, of compound i in the vent gas, as determined by Reference Method 18
MWi	=	The molecular weight of organic compound i in the vent gas, kg/kg-mol
0.0416	=	The conversion factor for molar volume, kg-mol/m3, at 293 K and 760 mm Hg
10-6	=	The conversion factor from ppm

 

ii)         For a source utilizing Reference Method 25A:

 



 

Where:

 

Eh	=	The total organic mass flow rate, kg/h
Q	=	The volumetric flow rate of gases entering or exiting control device, dscm/h, as determined by Reference Method 2
C	=	The organic concentration in ppm, dry basis, of compound i in the vent gas, as determined by Reference Method 25A
MW	=	The molecular weight of propane, 44 kg/kg-mol
0.0416	=	The conversion factor for molar volume, kg-mol/m3, at 293 K and 760 mm Hg
10-6	=	The conversion factor from ppm

 

E)        The annual total organic emission rate must be determined by the following equation:

 

A = F x H

 

Where:

 

A	=	total organic emission rate, kg/y
F	=	the total organic mass flow rate, kg/h, as calculated in subsection (c)(1)(D)
H	=	the total annual hours of operation for the affected unit, h/y

 

F)         Total organic emissions from all affected process vents at the facility must be determined by summing the hourly total organic mass emissions rates (F, as determined in subsection (c)(1)(D)) and by summing the annual total organic mass emission rates (A, as determined in subsection (c)(1)(E)) for all affected process vents at the facility.

 

2)         The owner or operator must record such process information as is necessary to determine the conditions of the performance tests. Operations during periods of startup, shutdown, and malfunction do not constitute representative conditions for the purpose of a performance test.

 

3)         The owner or operator of an affected facility must provide, or cause to be provided, performance testing facilities as follows:

 

A)        Sampling ports adequate for the test methods specified in subsection (c)(1).

 

B)        Safe sampling platforms.

 

C)        Safe access to sampling platforms.

 

D)        Utilities for sampling and testing equipment.

 

4)         For the purpose of making compliance determinations, the time-weighted average of the results of the three runs must apply. In the event that a sample is accidentally lost or conditions occur in which one of the three runs must be discontinued because of forced shutdown, failure of an irreplaceable portion of the sample train, extreme meteorological conditions, or other circumstances beyond the owner or operator's control, compliance may, upon the Agency's approval, be determined using the average of the results of the two other runs.

 

d)         To show that a process vent associated with a hazardous waste distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation is not subject to the requirements of this Subpart AA, the owner or operator must make an initial determination that the time-weighted, annual average total organic concentration of the waste managed by the waste management unit is less than 10 ppmw using one of the following two methods:

 

1)         Direct measurement of the organic concentration of the waste using the following procedures:

 

A)        The owner or operator must take a minimum of four grab samples of waste for each wastestream managed in the affected unit under process conditions expected to cause the maximum waste organic concentration.

 

B)        For waste generated onsite, the grab samples must be collected at a point before the waste is exposed to the atmosphere, such as in an enclosed pipe or other closed system that is used to transfer the waste after generation to the first affected distillation, fractionation, thin-film evaporation, solvent extraction, or air or steam stripping operation. For waste generated offsite, the grab samples must be collected at the inlet to the first waste management unit that receives the waste provided the waste has been transferred to the facility in a closed system such as a tank truck and the waste is not diluted or mixed with other waste.

 

C)        Each sample must be analyzed and the total organic concentration of the sample must be computed using Method 9060A (Total Organic Carbon) of "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", USEPA publication number EPA-530/SW-846, incorporated by reference under 35 Ill. Adm. Code 720.111(a), or analyzed for its individual constituents.

 

D)        The arithmetic mean of the results of the analyses of the four samples apply for each wastestream managed in the unit in determining the time-weighted, annual average total organic concentration of the waste. The time-weighted average is to be calculated using the annual quantity of each waste stream processed and the mean organic concentration of each wastestream managed in the unit.

 

2)         Using knowledge of the waste to determine that its total organic concentration is less than 10 ppmw. Documentation of the waste determination is required. Examples of documentation that must be used to support a determination under this subsection (d)(2) include the following:

"Average volatile organic concentration" or "average VO concentration" means the mass-weighted average volatile organic concentration of a hazardous waste, as determined in accordance with the requirements of Section 725.984.

 

"Closure device" means a cap, hatch, lid, plug, seal, valve, or other type of fitting that blocks an opening in a cover so that when the device is secured in the closed position it prevents or reduces air pollutant emissions to the atmosphere.  Closure devices include devices that are detachable from the cover (e.g., a sampling port cap), manually operated (e.g., a hinged access lid or hatch), or automatically operated (e.g., a spring-loaded pressure relief valve).

 

"Continuous seal" means a seal that forms a continuous closure that completely covers the space between the edge of the floating roof and the wall of a tank.  A continuous seal may be a vapor-mounted seal, liquid-mounted seal, or metallic shoe seal.  A continuous seal may be constructed of fastened segments so as to form a continuous seal.

 

"Cover" means a device that provides a continuous barrier over the hazardous waste managed in a unit to prevent or reduce air emissions to the atmosphere.  A cover may have openings (such as access hatches, sampling ports, and gauge wells) that are necessary for operation, inspection, maintenance, or repair of the unit on which the cover is used.  A cover may be a separate piece of equipment that can be detached and removed from the unit or a cover may be formed by structural features permanently integrated into the design of the unit.

 

"Enclosure" means a structure that surrounds a tank or container, captures organic vapors emitted from the tank or container, and vents the captured vapors through a closed-vent system to a control device.

 

"External floating roof" means a pontoon-type or double-deck type cover that rests on the surface of a hazardous waste being managed in a tank with no fixed roof.

 

"Fixed roof" means a cover that is mounted on a unit in a stationary position and does not move with fluctuations in the level of the material managed in the unit.

 

"Floating membrane cover" means a cover consisting of a synthetic flexible membrane material that rests upon and is supported by the hazardous waste being managed in a surface impoundment.

 

"Floating roof" means a cover consisting of a double-deck, pontoon single-deck, or internal floating cover that rests upon and is supported by the material being contained, and is equipped with a continuous seal.

 

"Hard-piping" means pipe or tubing that is manufactured and properly installed in accordance with relevant standards and good engineering practices.

 

"In light material service" means that the container is used to manage a material for which both of the following conditions apply:  the vapor pressure of one or more of the organic constituents in the material is greater than 0.3 kilopascals (kPa) at 20 °C (1.2 inches H₂O at 68 °F); and the total concentration of the pure organic constituents having a vapor pressure greater than 0.3 kPa at 20 °C (1.2 inches H₂O at 68 °F) is equal to or greater than 20 percent by weight.

 

"Internal floating roof" means a cover that rests or floats on the material surface (but not necessarily in complete contact with it) inside a tank that has a fixed roof.

 

"Liquid-mounted seal" means a foam or liquid-filled primary seal mounted in contact with the hazardous waste between the tank wall and the floating roof, continuously around the circumference of the tank.

 

"Malfunction" means any sudden, infrequent, and not reasonably preventable failure of air pollution control equipment, process equipment, or a process to operate in a normal or usual manner.  A failure that is caused in part by poor maintenance or careless operation is not a malfunction.

 

"Maximum organic vapor pressure" means the sum of the individual organic constituent partial pressures exerted by the material contained in a tank at the maximum vapor pressure-causing conditions (i.e., temperature, agitation, pH effects of combining wastes, etc.) reasonably expected to occur in the tank. For the purpose of this Subpart CC, maximum organic vapor pressure is determined using the procedures specified in Section 725.984(c).

 

"Metallic shoe seal" means a continuous seal that is constructed of metal sheets that are held vertically against the wall of the tank by springs, weighted levers, or other mechanisms and that is connected to the floating roof by braces or other means.  A flexible coated fabric (envelope) spans the annular space between the metal sheet and the floating roof.

 

"No detectable organic emissions" means no escape of organics to the atmosphere, as determined using the procedure specified in Section 725.984(d).

 

"Point of waste origination" means as follows:

 

When the facility owner or operator is the generator of the hazardous waste, the "point of waste origination" means the point where a solid waste produced by a system, process, or waste management unit is determined to be a hazardous waste, as defined in 35 Ill. Adm. Code 721.

 

BOARD NOTE: In this case, this term is being used in a manner similar to the use of the term "point of generation" in air standards established for waste management operations under authority of the federal Clean Air Act in 40 CFR 60 (Standards of Performance for New Stationary Sources), 61 (National Emission Standards for Hazardous Air Pollutants), and 63 (National Emission Standards for Hazardous Air Pollutants for Source Categories).

 

When the facility owner and operator are not the generator of the hazardous waste, "point of waste origination" means the point where the owner or operator accepts delivery or takes possession of the hazardous waste.

 

"Point of waste treatment" means the point where a hazardous waste to be treated in accordance with Section 725.983(c)(2) exits the treatment process.  Any waste determination must be made before the waste is conveyed, handled, or otherwise managed in a manner that allows the waste to volatilize to the atmosphere.

 

"Safety device" means a closure device, such as a pressure relief valve, frangible disc, fusible plug, or any other type of device that functions exclusively to prevent physical damage or permanent deformation to a unit or its air emission control equipment by venting gases or vapors directly to the atmosphere during unsafe conditions resulting from an unplanned, accidental, or emergency event.  For the purpose of this Subpart CC, a safety device is not used for routine venting of gases or vapors from the vapor headspace underneath a cover such as during filling of the unit or to adjust the pressure in this vapor headspace in response to normal daily diurnal ambient temperature fluctuations.  A safety device is designed to remain in a closed position during normal operations and open only when the internal pressure, or another relevant parameter, exceeds the device threshold setting applicable to the air emission control equipment as determined by the owner or operator based on manufacturer recommendations, applicable regulations, fire protection and prevention codes, standard engineering codes and practices, or other requirements for the safe handling of flammable, ignitable, explosive, reactive, or hazardous materials.

 

"Single-seal system" means a floating roof having one continuous seal. This seal may be vapor-mounted, liquid-mounted, or a metallic shoe seal.

 

"Vapor-mounted seal" means a continuous seal that is mounted so that there is a vapor space between the hazardous waste in the unit and the bottom of the seal.

 

"Volatile organic concentration" or "VO concentration" means the fraction by weight of organic compounds contained in a hazardous waste expressed in terms of parts per million (ppmw), as determined by direct measurement or by knowledge of the waste, in accordance with the requirements of Section 725.984.  For the purpose of determining the VO concentration of a hazardous waste, organic compounds with a Henry's law constant value of at least 0.1 mole-fraction-in-the-gas-phase/mole- fraction-in-the-liquid-phase (0.1 Y/X) (which can also be expressed as 1.8x10^-6 atmospheres/gram-mole/m³) at 25 °C (77 °F) must be included. Appendix F presents a list of compounds known to have a Henry's law constant value less than the cutoff level.

 

"Waste determination" means performing all applicable procedures in accordance with the requirements of Section 725.984 to determine whether a hazardous waste meets standards specified in this Subpart CC.  Examples of a waste determination include performing the procedures in accordance with the requirements of Section 725.984 to determine the average VO concentration of a hazardous waste at the point of waste origination, determining the average VO concentration of a hazardous waste at the point of waste treatment and comparing the results to the exit concentration limit specified for the process used to treat the hazardous waste, the organic reduction efficiency and the organic biodegradation efficiency for a biological process used to treat a hazardous waste and comparing the results to the applicable standards, or determining the maximum volatile organic vapor pressure for a hazardous waste in a tank and comparing the results to the applicable standards.

 

"Waste stabilization process" means any physical or chemical process used to either reduce the mobility of hazardous constituents in a hazardous waste or eliminate free liquids as determined by Test Method 9095B (Paint Filter Liquids Test) in "Test Methods for Evaluating Solid Waste, Physical/Chemical Methods", USEPA publication number EPA-530/SW-846, incorporated by reference in 35 Ill. Adm. Code 720.111(a).  A waste stabilization process includes mixing the hazardous waste with binders or other materials and curing the resulting hazardous waste and binder mixture.  Other synonymous terms used to refer to this process are "waste fixation" or "waste solidification". This does not include the addition of absorbent materials to the surface of a waste to absorb free liquid without mixing, agitation, or subsequent curing.

Section 725.984  Waste Determination Procedures

 

a)         Determination of Volatile Organic (VO) Concentration at the Point of Waste Origination

 

1)         An owner or operator must determine the average VO concentration at the point of waste origination for each hazardous waste placed in a waste management unit exempted under the provisions of Section 725.983(c)(1) from using air emission controls in accordance with standards specified in Section 725.985 through Section 725.988, as applicable to the waste management unit.

 

A)        An owner or operator must make an initial determination of the average VO concentration of the waste stream before the first time any portion of the material in the hazardous waste stream is placed in a waste management unit exempted under the provisions of Section 725.983(c)(1) from using air emission controls.  Thereafter, an owner or operator must make an initial determination of the average VO concentration of the waste stream for each averaging period that a hazardous waste is managed in the unit.

 

B)        An owner or operator must perform a new waste determination whenever changes to the source generating the waste stream are reasonably likely to cause the average VO concentration of the hazardous waste to increase to a level that is equal to or greater than the VO concentration limits specified in Section 725.983(c)(1).

 

2)         For a waste determination that is required by subsection (a)(1), the average VO concentration of a hazardous waste at the point of waste origination must be determined using either direct measurement, as specified in subsection (a)(3), or by knowledge of the waste, as specified in subsection (a)(4).

 

3)         Direct Measurement

 

A)        Identification.  The owner or operator must identify and record the point of waste origination for the hazardous waste.

 

B)        Sampling.  Samples of the hazardous waste stream must be collected at the point of waste origination in such a manner that volatilization of organics contained in the waste and in the subsequent sample is minimized and an adequately representative sample is collected and maintained for analysis by the selected method.

 

i)          The averaging period to be used for determining the average VO concentration for the hazardous waste stream on a mass-weighted average basis must be designated and recorded.  The averaging period can represent any time interval that the owner or operator determines is appropriate for the hazardous waste stream but must not exceed one year.

 

ii)         A sufficient number of samples, but no fewer than four samples, must be collected for a hazardous waste determination. All of the samples for a given waste determination must be collected within a one-hour period.  The average of the four or more sample results constitutes a waste determination for the waste stream.  One or more waste determinations may be required to represent the complete range of waste compositions and quantities that occur during the entire averaging period due to normal variations in the operating conditions for the source or process generating the hazardous waste stream.  Examples of such normal variations are seasonal variations in waste quantity or fluctuations in ambient temperature.

 

iii)        All samples must be collected and handled in accordance with written procedures prepared by the owner or operator and documented in a site sampling plan.  This plan must describe the procedure by which representative samples of the hazardous waste stream are collected so that a minimum loss of organics occurs throughout the sample collection and handling process, and by which sample integrity is maintained.  A copy of the written sampling plan must be maintained on-site in the facility operating records.  An example of an acceptable sampling plan includes a plan incorporating sample collection and handling procedures in Reference Method 25D (Determination of the Volatile Organic Concentration of Waste Samples) in appendix A to 40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b).

 

iv)        Sufficient information, as specified in the "site sampling plan" required under subsection (a)(3)(B)(iii), must be prepared and recorded to document the waste quantity represented by the samples and, as applicable, the operating conditions for the source or process generating the hazardous waste represented by the samples.

 

C)        Analysis.  Each collected sample must be prepared and analyzed in accordance with Reference Method 25D in appendix A to 40 CFR 60 for the total concentration of volatile organic constituents or using one or more methods when the individual organic compound concentrations are identified and summed and the summed waste concentration accounts for and reflects all organic compounds  in the waste with Henry's law constant values at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X) (which can also be expressed as 1.8 x 10^-6 atmospheres/

gram-mole/m³) at 25 °C (77 °F). At the owner's or operator's discretion, the owner or operator may adjust test data measured by any appropriate method to discount any contribution to the total volatile organic concentration that is a result of including a compound with a Henry's law constant value of less than 0.1 Y/X at 25 °C. If the owner or operator elects to adjust test data, the adjustment must be made to all individual chemical constituents with a Henry's law constant value greater than or equal to 0.1 Y/X at 25 °C contained in the waste. To adjust these data, the measured concentration of each individual chemical constituent contained in the waste is multiplied by the constituent-specific adjustment factor (f_m25D) approved in writing by the Agency.  Other test methods may be used if they meet the requirements in subsection (a)(3)(C)(i) or (a)(3)(C)(ii) and provided the requirement is met to reflect all organic compounds in the waste with Henry's law constant values greater than or equal to 0.1 Y/X (which can also be expressed as 1.8 x 10^-6 atmospheres/gram-mole/m³) at 25 °C.

 

i)          Any USEPA standard method that has been validated in accordance with appendix D to 40 CFR 63 (Alternative Validation Procedure for EPA Waste and Wastewater Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b); or

 

ii)         Any other analysis method that has been validated in accordance with the procedures specified in Section 5.1 or 5.3, and the corresponding calculations in Section 6.1 or 6.3, of Method 301 (Field Validation of Pollutant Measurement Methods from Various Waste Media) in appendix A to 40 CFR 63 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b).  The data are acceptable if they meet the criteria specified in Section 6.1.5 or 6.3.3 of Method 301.  If correction is required under Section 6.3.3 of Method 301, the data are acceptable if the correction factor is within the range 0.7 to 1.30.  Other sections of Method 301 are not required.

 

D)        Calculations

 

i)          The average VO concentration () on a mass-weighted basis must be calculated by using the results for all waste determinations conducted in accordance with subsections (a)(3)(B) and (a)(3)(C) and the following equation:

 



 

Where:

 

	=	Average VO concentration of the hazardous waste at the point of waste origination on a mass-weighted basis, in ppmw
i	=	Individual waste determination "i" of the hazardous waste
n	=	Total number of waste determinations of the hazardous waste conducted for the averaging period (not to exceed one year)
Qi	=	Mass quantity of the hazardous waste stream represented by Ci, in kg/hr
QT	=	Total mass quantity of the hazardous waste during the averaging period, in kg/hr
Ci	=	Measured VO concentration of waste determination "i", as determined in accordance with subsection (a)(3)(C) (i.e., the average of the four or more samples specified in subsection (a)(3)(B)(ii)), in ppmw

 

ii)         For the purpose of determining C_i, for individual waste samples analyzed in accordance with subsection (a)(3)(C), the owner or operator must account for VO concentrations determined to be below the limit of detection of the analytical method by using the VO concentration determined according to subsection (a)(3)(G).

 

E)        Provided that the test method is appropriate for the waste as required under subsection (a)(3)(C), the Agency must determine compliance based on the test method used by the owner or operator as recorded under Section 725.990(f)(1).

 

F)         The quality assurance program elements required under subsections (a)(3)(C)(vi) and (a)(3)(C)(vii) are as follows:

 

i)          Documentation of site-specific procedures to minimize the loss of compounds due to volatilization, biodegradation, reaction, or sorption during the sample collection, storage, preparation, introduction, and analysis steps.

 

ii)         Measurement of the overall accuracy and precision of the specific procedures.

 

BOARD NOTE:  Subsections (a)(3)(F)(i) and (a)(3)(F)(ii) are derived from 40 CFR 265.984(a)(3)(iii)(F)(1), (a)(3)(iii)(F)(2), (a)(3)(iii)(G)(1), and (a)(3)(iii)(G)(2), which the Board has codified here to comport with Illinois Administrative Code format requirements.

i)          If Reference Method 25D is used for the analysis, the VO concentration must be considered to be one-half the blank value determined in the method at Section 4.4 of Reference Method 25D.

 

ii)         If any other analytical method is used, the VO concentration must be considered to be one-half the sum of the limits of detection established for each organic constituent in the waste that has a Henry's law constant value at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X) (which can also be expressed as 1.8 x 10^-6 atmospheres/gram-mole/m³) at 25 °C (77 °F).

 

BOARD NOTE:  Subsections (a)(3)(G)(i) and (a)(3)(G)(ii) are derived from 40 CFR 265.984(a)(3)(iv)(A)(1) and (a)(3)(iv)(A)(2), which the Board has codified here to comport with Illinois Administrative Code format requirements.

 

4)         Use of Owner or Operator Knowledge

 

A)        Documentation must be prepared that presents the information used as the basis for the owner's or operator's knowledge of the hazardous waste stream's average VO concentration.  Examples of information that may be used as the basis for knowledge include the following:  material balances for the source or process generating the hazardous waste stream; constituent-specific chemical test data for the hazardous waste stream from previous testing that are still applicable to the current waste stream; previous test data for other locations managing the same type of waste stream; or other knowledge based on information included in manifests, shipping papers, or waste certification notices.

 

B)        If test data are used as the basis for knowledge, then the owner or operator must document the test method, sampling protocol, and the means by which sampling variability and analytical variability are accounted for in the determination of the average VO concentration.  For example, an owner or operator may use organic concentration test data for the hazardous waste stream that are validated in accordance with Method 301 as the basis for knowledge of the waste.

 

C)        An owner or operator using chemical constituent-specific concentration test data as the basis for knowledge of the hazardous waste may adjust the test data to the corresponding average VO concentration value that would have been obtained had the waste samples been analyzed using Reference Method 25D.  To adjust these data, the measured concentration for each individual chemical constituent contained in the waste is multiplied by the appropriate constituent-specific adjustment factor (f_m25D).

 

D)        In the event that the Agency and the owner or operator disagree on a determination of the average VO concentration for a hazardous waste stream using knowledge, then the results from a determination of average VO concentration using direct measurement, as specified in subsection (a)(3), must be used to establish compliance with the applicable requirements of this Subpart CC. The Agency may perform or request that the owner or operator perform this determination using direct measurement.  The owner or operator may choose one or more appropriate methods to analyze each collected sample in accordance with the requirements of subsection (a)(3)(C).

 

b)         Determination of VO Concentration at the Point of Waste Treatment

 

1)         An owner or operator must perform the applicable waste determination for each treated hazardous waste placed in a waste management unit exempted under the provisions of Section 725.983(c)(2)(A) through (c)(2)(F) from using air emission controls in accordance with the standards specified in Sections 725.985 through 725.988, as applicable to the waste management unit.

 

A)        An owner or operator must make an initial determination of the average VO concentration of the waste stream before the first time any portion of the material in the treated waste stream is placed in the waste management unit exempt under Section 725.983(c)(2), (c)(3), or (c)(4) from using air emission controls.  Thereafter, an owner or operator must update the information used for the waste determination at least once every 12 months following the date of the initial waste determination.

 

B)        An owner or operator must perform a new waste determination whenever changes to the process generating or treating the waste stream are reasonably likely to cause the average VO concentration of the hazardous waste to increase to such a level that the applicable treatment conditions specified in Section 725.983(c)(2), (c)(3), or (c)(4) are not achieved.

 

2)         The owner or operator must designate and record the specific provision in Section 725.983(c)(2) under which the waste determination is being performed. The waste determination for the treated hazardous waste must be performed using the applicable procedures specified in subsections (b)(3) through (b)(9).

 

3)         Procedure for Determination of VO Concentration

 

A)        Identification.  The owner or operator must identify and record the point of waste treatment for the hazardous waste.

 

B)        Sampling.  Samples of the hazardous waste stream must be collected at the point of waste treatment in such a manner that volatilization of organics contained in the waste and in the subsequent sample is minimized and an adequately representative sample is collected and maintained for analysis by the selected method.

 

i)          The averaging period to be used for determining the average VO concentration for the hazardous waste stream on a mass-weighted average basis must be designated and recorded.  The averaging period can represent any time interval that the owner or operator determines is appropriate for the hazardous waste stream but must not exceed one year.

 

ii)         A sufficient number of samples, but no fewer than four samples, must be collected and analyzed for a hazardous waste determination.  All of the samples for a given waste determination must be collected within a one-hour period.  The average of the four or more sample results constitutes a waste determination for the hazardous waste stream.  One or more waste determinations may be required to represent the complete range of waste compositions and quantities that occur during the entire averaging period due to normal variations in the operating conditions for the process generating or treating the hazardous waste stream.  Examples of such normal variations are seasonal variations in waste quantity or fluctuations in ambient temperature.

 

iii)        All samples must be collected and handled in accordance with written procedures prepared by the owner or operator and documented in a site sampling plan. This plan must describe the procedure by which representative samples of the hazardous waste stream are collected so that a minimum loss of organics occurs throughout the sample collection and handling process, and by which sample integrity is maintained. A copy of the written sampling plan must be maintained on-site in the facility operating records. An example of an acceptable sample collection and handling procedures for a total organic constituent concentration may be found in Reference Method 25D.

 

iv)        Sufficient information, as specified in the "site sampling plan" required under subsection (a)(3)(B)(iii), must be prepared and recorded to document the waste quantity represented by the samples and, as applicable, the operating conditions for the process treating the hazardous waste represented by the samples.

 

C)        Analysis.  Each collected sample must be prepared and analyzed in accordance with Reference Method 25D for the total concentration of volatile organic constituents or using one or more methods when the individual organic compound concentrations are identified and summed, and the summed waste concentration accounts for and reflects all organic compounds in the waste with Henry's law constant values at least 0.1 mole-fraction-in-the-gas-phase/mole-fraction-in-the-liquid-phase (0.1 Y/X) (which can also be expressed as 1.8 x 10^-6 atmospheres/gram-mole/m³) at 25 °C (77° F).  When the owner or operator is making a waste determination for a treated hazardous waste that is to be compared to an average VO concentration at the point of waste origination or the point of waste entry to the treatment system, to determine if the conditions of 35 Ill. Adm. Code 724.982(c)(2)(A) through (c)(2)(F) or Section 725.983(c)(2)(A) through (c)(2)(F) are met, then the waste samples must be prepared and analyzed using the same method or methods as were used in making the initial waste determinations at the point of waste origination or at the point of entry to the treatment system.  At the owner's or operator's discretion, the owner or operator may adjust test data  obtained by any appropriate method to discount any contribution to the total volatile organic concentration that is a result of including a compound with a Henry's law constant value less than 0.1 Y/X at 25 °C. If the owner or operator elects to adjust test data, the adjustment must be made to all individual chemical constituents with a Henry's law constant value greater than or equal to 0.1 Y/X at 25 °C contained  in the waste. To adjust these data, the measured concentration of each individual chemical constituent contained in the waste is multiplied by the constituent-specific adjustment factor (f_m25D) approved in writing by the Agency.  Other test methods may be used if they meet the requirements in subsection (a)(3)(C)(i) or (a)(3)(C)(ii) and provided the requirement is met to reflect all organic compounds in the waste with Henry's law constant values greater than or equal to 0.1 Y/X (which can also be expressed as 1.8 x 10^-6 atmospheres/gram-mole/m³) at 25 °C.

 

i)         Any USEPA standard method that has been validated in accordance with appendix D to 40 CFR 63, incorporated by reference in 35 Ill. Adm. Code 720.111(b); or

 

ii)         Any other analysis method that has been validated in accordance with the procedures specified in Section 5.1 or 5.3, and the corresponding calculations in Section 6.1 or 6.3, of Method 301 in appendix A to 40 CFR 63, incorporated by reference in 35 Ill. Adm. Code 720.111(b).  The data are acceptable if they meet the criteria specified in Section 6.1.5 or 6.3.3 of Method 301.  If correction is required under Section 6.3.3 of Method 301, the data are acceptable if the correction factor is within the range 0.7 to 1.30.  Other sections of Method 301 are not required.

 

D)        Calculations.  The average VO concentration () on a mass-weighted basis must be calculated by using the results for all samples analyzed in accordance with subsection (b)(3)(C) and the following equation:

2)         An owner or operator must use either direct measurement, as specified in subsection (c)(3), or knowledge of the waste, as specified by subsection (c)(4), to determine the maximum organic vapor pressure that is representative of the hazardous waste composition stored or treated in the tank.

 

3)         Direct Measurement to Determine VO

 

A)        Sampling.  A sufficient number of samples must be collected to be representative of the waste contained in the tank.  All samples must be conducted and handled in accordance with written procedures prepared by the owner or operator and documented in a site sampling plan.  This plan must describe the procedure by which representative samples of the hazardous waste are collected so that a minimum loss of organics occurs throughout the sample collection and handling process and by which sample integrity is maintained.  A copy of the written sampling plan must be maintained on-site in the facility operating records.  An example of acceptable sample collection and handling procedures may be found in Reference Method 25D.

 

B)        Analysis. Any appropriate one of the following methods may be used to analyze the samples and compute the maximum organic vapor pressure of the hazardous waste:

 

i)          Reference Method 25E (Determination of Vapor Phase Organic Concentration in Waste Samples) in appendix A to 40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b);

 

ii)         Methods described in API publication 2517 (Evaporative Loss from External Floating-Roof Tanks), incorporated by reference in 35 Ill. Adm. Code 720.111(a);

 

iii)        Methods obtained from standard reference texts;

 

iv)        ASTM Method D 2879-92 (Standard Test Method for Vapor Pressure-Temperature Relationship and Initial Decomposition Temperature of Liquids by Isoteniscope), incorporated by reference in 35 Ill. Adm. Code 720.111(a); or

 

v)         Any other method approved by the Agency.

 

4)         Use of Knowledge to Determine the Maximum Organic Vapor Pressure of the Hazardous Waste.  Documentation must be prepared and recorded that presents the information used as the basis for the owner's or operator's knowledge that the maximum organic vapor pressure of the hazardous waste is less than the maximum vapor pressure limit listed in Section 725.985(b)(1)(A) for the applicable tank design capacity category.  An example of information that may be used is documentation that the hazardous waste is generated by a process for which at other locations it previously has been determined by direct measurement that the waste maximum organic vapor pressure is less than the maximum vapor pressure limit for the appropriate tank design capacity category.

 

d)         The procedure for determining no detectable organic emissions for the purpose of complying with this Subpart CC is as follows:

 

1)         The test must be conducted in accordance with the procedures specified in Reference Method 21 (Determination of Volatile Organic Compound Leaks) of appendix A to 40 CFR 60 (Test Methods), incorporated by reference in 35 Ill. Adm. Code 720.111(b).  Each potential leak interface (i.e., a location where organic vapor leakage could occur) on the cover and associated closure devices must be checked.  Potential leak interfaces that are associated with covers and closure devices include, but are not limited to, any of the following:  the interface of the cover and its foundation mounting, the periphery of any opening on the cover and its associated closure device, and the sealing seat interface on a spring-loaded pressure relief valve.

 

2)         The test must be performed when the unit contains a hazardous waste having an organic concentration representative of the range of concentrations for the hazardous waste expected to be managed in the unit.  During the test, the cover and closure devices must be secured in the closed position.

 

3)         The detection instrument must meet the performance criteria of Reference Method 21, except the instrument response factor criteria in Section 3.1.2(a) of Reference Method 21 must be for the average composition of the organic constituents in the hazardous waste placed in the waste management unit, not for each individual organic constituent.

 

4)         The detection instrument must be calibrated before use on each day of its use by the procedures specified in Reference Method 21.

 

5)         Calibration gases must be as follows:

 

A)        Zero air (less than 10 ppmv hydrocarbon in air), and

 

B)        A mixture of methane or n-hexane in air at a concentration of approximately, but less than, 10,000 ppmv methane or n-hexane.

 

6)         The background level must be determined according to the procedures in Reference Method 21.

 

7)         Each potential leak interface must be checked by traversing the instrument probe around the potential leak interface as close to the interface as possible, as described in Reference Method 21.  If the configuration of the cover or closure device prevents a complete traverse of the interface, all accessible portions of the interface must be sampled.  If the configuration of the closure device prevents any sampling at the interface and the device is equipped with an enclosed extension or horn (e.g., some pressure relief devices), the instrument probe inlet must be placed at approximately the center of the exhaust area to the atmosphere.

 

8)         The arithmetic difference between the maximum organic concentration indicated by the instrument and the background level must be compared with the value of 500 ppmv except when monitoring a seal around a rotating shaft that passes through a cover opening, in which case the comparison must be as specified in subsection (d)(9).  If the difference is less than 500 ppmv, then the potential leak interface is determined to operate with no detectable organic emissions.

 

9)         For the seals around a rotating shaft that passes through a cover opening, the arithmetic difference between the maximum organic concentration indicated by the instrument and the background level must be compared with the value of 10,000 ppmw.  If the difference is less than 10,000 ppmw, then the potential leak interface is determined to operate with no detectable organic emissions.

Section 725.985  Standards:  Tanks

 

a)         The provisions of this Section apply to the control of air pollutant emissions from tanks for which Section 725.983(b) references the use of this Section for such air emission control.

 

b)         The owner or operator must control air pollutant emissions from each tank subject to this Section in accordance with the following requirements, as applicable:

 

1)         For a tank that manages hazardous waste that meets all of the conditions specified in subsections (b)(1)(A) through (b)(1)(C), the owner or operator must control air pollutant emissions from the tank in accordance with the Tank Level 1 controls specified in subsection (c) or the Tank Level 2 controls specified in subsection (d).

 

A)        The hazardous waste in the tank has a maximum organic vapor pressure that is less than the maximum organic vapor pressure limit for the tank's design capacity category, as follows:

 

i)          For a tank design capacity equal to or greater than 151 m³ (5333 ft³ or 39,887 gal), the maximum organic vapor pressure limit for the tank is 5.2 kPa (0.75 psia or 39 mm Hg);

 

ii)         For a tank design capacity equal to or greater than 75 m³ (2649 ft³ or 19,810 gal) but less than 151 m³ (5333 ft³ or 39,887 gal), the maximum organic vapor pressure limit for the tank is 27.6 kPa (4.0 psia or 207 mm Hg); or

 

iii)        For a tank design capacity less than 75 m³ (2649 ft³or 19,810 gal), the maximum organic vapor pressure limit for the tank is 76.6 kPa (11.1 psia or 574 mm Hg).

1)         The owner or operator must determine the maximum organic vapor pressure for a hazardous waste to be managed in the tank using Tank Level 1 controls before the first time the hazardous waste is placed in the tank.  The maximum organic vapor pressure must be determined using the procedures specified in Section 725.984(c).  Thereafter, the owner or operator must perform a new determination whenever changes to the hazardous waste managed in the tank could potentially cause the maximum organic vapor pressure to increase to a level that is equal to or greater than the maximum organic vapor pressure limit for the tank design capacity category specified in subsection (b)(1)(A), as applicable to the tank.

 

2)         The tank must be equipped with a fixed roof designed to meet the following specifications:

 

A)        The fixed roof and its closure devices must be designed to form a continuous barrier over the entire surface area of the hazardous waste in the tank.  The fixed roof may be a separate cover installed on the tank (e.g., a removable cover mounted on an open-top tank) or may be an integral part of the tank structural design (e.g., a horizontal cylindrical tank equipped with a hatch).

 

B)        The fixed roof must be installed in such a manner that there are no visible cracks, holes, gaps, or other open spaces between roof section joints or between the interface of the roof edge and the tank wall.

c)         Container Level 1 Standards.

 

1)         A container using Container Level 1 controls is one of the following:

 

A)        A container that meets the applicable USDOT regulations on packaging hazardous materials for transportation, as specified in subsection (f);

 

B)        A container equipped with a cover and closure devices that form a continuous barrier over the container openings so that when the cover and closure devices are secured in the closed position there are no visible holes, gaps, or other open spaces into the interior of the container.  The cover may be a separate cover installed on the container (e.g., a lid on a drum or a suitably secured tarp on a roll-off box) or may be an integral part of the container structural design (e.g., a "portable tank" or bulk cargo container equipped with a screw-type cap); and

 

C)        An open-top container in which an organic-vapor suppressing barrier is placed on or over the hazardous waste in the container so that no hazardous waste is exposed to the atmosphere.  One example of such a barrier is application of a suitable organic-vapor suppressing foam.

 

2)         A container used to meet the requirements of subsection (c)(1)(B) or (c)(1)(C) must be equipped with covers and closure devices, as applicable to the container, that are composed of suitable materials to minimize exposure of the hazardous waste to the atmosphere and to maintain the equipment integrity for as long as it is in service.  Factors to be considered in selecting the materials of construction and designing the cover and closure devices must include the following:  the organic vapor permeability; the effects of contact with the hazardous waste or its vapor managed in the container; the effects of outdoor exposure of the closure device or cover material to wind, moisture, and sunlight; and the operating practices for which the container is intended to be used.

 

3)         Whenever a hazardous waste is in a container using Container Level 1 controls, the owner or operator must install all covers and closure devices for the container, as applicable to the container, and secure and maintain each closure device in the closed position except as follows:

 

A)        Opening of a closure device or cover is allowed for the purpose of adding hazardous waste or other material to the container, as follows:

 

i)          If the container is filled to the intended final level in one continuous operation, the owner or operator must promptly secure the closure devices in the closed position and install the covers, as applicable to the container, upon conclusion of the filling operation; and

 

ii)         If discrete quantities or batches of material intermittently are added to the container over a period of time, the owner or operator must promptly secure the closure devices in the closed position and install covers, as applicable to the container, upon either the container being filled to the intended final level; the completion of a batch loading after which no additional material will be added to the container within 15 minutes; the person performing the loading operation leaving the immediate vicinity of the container; or the shutdown of the process generating the material being added to the container, whichever condition occurs first;

 

B)        Opening of a closure device or cover is allowed for the purpose of removing hazardous waste from the container as follows:

 

i)          For the purpose of meeting the requirements of this Section, an empty container, as defined in 35 Ill. Adm. Code 721.107(b), may be open to the atmosphere at any time (i.e., covers and closure devices are not required to be secured in the closed position on an empty container); and

 

ii)         If discrete quantities or batches of material are removed from the container but the container does not meet the conditions to be an empty container, as defined in 35 Ill. Adm. Code 721.107(b), the owner or operator must promptly secure the closure devices in the closed position and install covers, as applicable to the container, upon the completion of a batch removal after which no additional material will be removed from the container within 15 minutes or the person performing the unloading operation leaves the immediate vicinity of the container, whichever condition occurs first;

 

C)        Opening of a closure device or cover is allowed when access inside the container is needed to perform routine activities other than transfer of hazardous waste.  Examples of such activities include those times when a worker needs to open a port to measure the depth of or sample the material in the container, or when a worker needs to open a manhole hatch to access equipment inside the container.  Following completion of the activity, the owner or operator must promptly secure the closure device in the closed position or reinstall the cover, as applicable to the container;

 

D)        Opening of a spring-loaded, pressure-vacuum relief valve, conservation vent, or similar type of pressure relief device that vents to the atmosphere is allowed during normal operations for the purpose of maintaining the container internal pressure in accordance with the design specifications of the container.  The device must be designed to operate with no detectable organic emissions when the device is secured in the closed position.  The settings at which the device opens must be established so that the device remains in the closed position whenever the internal pressure of the container is within the internal pressure operating range determined by the owner or operator based on container manufacturer recommendations, applicable regulations, fire protection and prevention codes, standard engineering codes and practices, or other requirements for the safe handling of flammable, ignitable, explosive, reactive, or hazardous materials.  Examples of normal operating conditions that may require these devices to open are during those times when the internal pressure of the container exceeds the internal pressure operating range for the container as a result of loading operations or diurnal ambient temperature fluctuations; and

 

E)        Opening of a safety device, as defined in Section 725.981, is allowed at any time conditions require doing so to avoid an unsafe condition.

 

4)         The owner or operator of containers using Container Level 1 controls must inspect the containers and their covers and closure devices as follows:

 

A)        If a hazardous waste already is in the container at the time the owner or operator first accepts possession of the container at the facility and the container is not emptied within 24 hours after the container is accepted at the facility (i.e., it does not meet the conditions for an empty container as specified in 35 Ill. Adm. Code 721.107(b)), the owner or operator must visually inspect the container and its cover and closure devices to check for visible cracks, holes, gaps, or other open spaces into the interior of the container when the cover and closure devices are secured in the closed position.  The container visual inspection must be conducted on or before the date on which the container is accepted at the facility (i.e., the date when the container becomes subject to the Subpart CC container standards).  For the purposes of this requirement, the date of acceptance is the date of signature that the facility owner or operator enters on Item 20 of the Uniform Hazardous Waste Manifest (USEPA Form 8700-22), incorporated by reference in 35 Ill. Adm. Code 720.111(b), as required under Section 725.171.  If a defect is detected, the owner or operator must repair the defect in accordance with the requirements of subsection (c)(4)(C);

 

B)        If a container used for managing hazardous waste remains at the facility for a period of one year or more, the owner or operator must visually inspect the container and its cover and closure devices initially and thereafter, at least once every 12 months, to check for visible cracks, holes, gaps, or other open spaces into the interior of the container when the cover and closure devices are secured in the closed position.  If a defect is detected, the owner or operator must repair the defect in accordance with the requirements of subsection (c)(4)(C); and

 

C)        When a defect is detected in the container, cover, or closure devices, the owner or operator must make first efforts at repair of the defect no later than 24 hours after detection, and repair must be completed as soon as possible but no later than five calendar days after detection.  If repair of a defect cannot be completed within five calendar days, then the hazardous waste must be removed from the container and the container must not be used to manage hazardous waste until the defect is repaired.

 

5)         The owner or operator must maintain at the facility a copy of the procedure used to determine that containers with capacity of 0.46 m³ (120 gal) or greater which do not meet applicable USDOT regulations, as specified in subsection (f), are not managing hazardous waste in light material service.
