CHAPTER I: POLLUTION CONTROL BOARD
PART 724 STANDARDS FOR OWNERS AND OPERATORS OF HAZARDOUS WASTE TREATMENT, STORAGE, AND DISPOSAL FACILITIES
SECTION 724.118 LOCATION STANDARDS


 

Section 724.118 Location Standards

 

a) Seismic considerations.

 

1) Portions of new facilities where treatment, storage or disposal of hazardous waste will be conducted must not be located within 61 meters (200 feet) of a fault that has had displacement in Holocene time.

 

2) As used in subsection (a)(1) of this Section:

 

A) "Fault" means a fracture along which rocks on one side have been displaced with respect to those on the other side.

 

B) "Displacement" means the relative movement of any two sides of a fault measured in any direction.

 

C) "Holocene" means the most recent epoch of the Quaternary period, extending from the end of the Pleistocene to the present.

 

BOARD NOTE: Procedures for demonstrating compliance with this standard in Part B of the permit application are specified in 35 Ill. Adm. Code 703.182. Facilities that are located in political jurisdictions other than those listed in appendix VI to 40 CFR 264 (Political Jurisdictions in Which Compliance with 264.18(a) Must Be Demonstrated), incorporated by reference in 35 Ill. Adm. Code 720.111(b), are assumed to be in compliance with this requirement.

 

b) Floodplains.

 

1) A facility located in a 100-year floodplain must be designed, constructed, operated and maintained to prevent washout of any hazardous waste by a 100-year flood, unless the owner or operator can demonstrate the following to the Agency's satisfaction:

 

A) That procedures are in effect that will cause the waste to be removed safely, before flood waters can reach the facility, to a location where the wastes will not be vulnerable to flood waters; or

 

B) For existing surface impoundments, waste piles, land treatment units, landfills and miscellaneous units, that no adverse effect on human health or the environment will result if washout occurs, considering the following:

 

i) The volume and physical and chemical characteristics of the waste in the facility;

 

ii) The concentration of hazardous constituents that would potentially affect surface waters as a result of washout;

 

iii) The impact of such concentrations on the current or potential uses of and water quality standards established for the affected surface waters; and

 

iv) The impact of hazardous constituents on the sediments of affected surface waters or the soils of the 100-year floodplain that could result from washout;

 

2) As used in subsection (b)(1) of this Section:

 

A) "100-year floodplain" means any land area that is subject to a one percent or greater chance of flooding in any given year from any source.

 

B) "Washout" means the movement of hazardous waste from the active portion of the facility as a result of flooding.

 

C) "100-year flood" means a flood that has a one percent chance of being equalled or exceeded in any given year.

 

BOARD NOTE: Requirements pertaining to other federal laws that affect the location and permitting of facilities are found in 40 CFR 270.3. For details relative to these laws, see EPA's manual for SEA (special environmental area) requirements for hazardous waste facility permits. Though EPA is responsible for complying with these requirements, applicants are advised to consider them in planning the location of a facility to help prevent subsequent project delays. Facilities may be required to obtain from the Illinois Department of Transportation on a permit or certification that a facility is flood-proofed.

 

c) Salt dome formations, salt bed formations, underground mines and caves. The placement of any non-containerized or bulk liquid hazardous waste in any salt dome formation, salt bed formation, underground cave or mine is prohibited.
