Section 900.35 Revised Total Coliform Rule for
Non-Community Public Water Systems
a) Sanitary
Surveys
1) A
biennial sanitary survey shall be obtained by all non-community public water
systems that are not recreational facilities licensed by the Department.
2) All
non-community public water supplies licensed by the Department as recreational
facilities shall obtain an annual sanitary survey.
3) Special
Monitoring Evaluation
A) To determine whether the system is on an
appropriate monitoring schedule, the Department will perform a special
monitoring evaluation during each sanitary survey. After the Department has
performed the special monitoring evaluation, it may modify the system's
monitoring schedule.
B) For
seasonal systems on quarterly or annual monitoring, the special monitoring
evaluation will include review of the approved sample siting plan, which must
designate the time period or periods for monitoring based on site-specific
considerations (e.g., during periods of highest demand or highest vulnerability
to contamination).
b) Monitoring
1) Routine
Monitoring
A) A
non-community water system supplier using only groundwater, excluding
groundwater under the direct influence of surface water, as defined in 35 Ill.
Adm. Code 611.102, and serving 1,000 persons or fewer must conduct the
following total coliform and E.coli monitoring:
i) Quarterly
Monitoring. The supplier must monitor each calendar quarter that the system
provides water to the public.
ii) Reduced
Monitoring. The Department may reduce the quarterly monitoring frequency to
not less than annually, if the most recent sanitary survey shows that the
system is free of sanitary defects, has a protected water source and the wells
conform to the requirements of the Water Well Construction Code.
B) Non-community
water systems that do not meet the requirements of subsection (b)(1)(A) are
subject to the monitoring requirements of 35 Ill Adm. Code 611.1056 and
611.1057 except vending machines classified as non-community water systems,
which must comply with (b)(1)(A).
C) Monitoring
after E. coli Violations
i) A
water system that incurs an E. coli violation, as specified in subsection
(h)(1), shall be placed on monthly monitoring for a minimum of one year beginning in the next month in which the supplier
provides water to the public, unless the cause of the violation has been
definitely determined by the Department and corrected prior to water being
served to the public.
ii) When
the cause of the violation has not been definitely determined by the Department
and corrected, monitoring must be conducted during the most vulnerable times
each month for the next 12 months following an E. coli MCL violation. If any
sample result (routine, repeat, additional routine, or clearance sample) is
Total Coliform Positive within 12 months following the MCL violation, the
system must collect monthly samples for a minimum of 12 consecutive months.
Monthly monitoring must begin in the next month in which the supplier provides
water to the public.
iii) After
12 consecutive months of monitoring, the Department may allow
the water system to return to quarterly monitoring in accordance with
subsection (b)(1)(A) if the water system meets the criteria specified in subsection
(b)(1)(E).
D) A
water system that incurs a coliform treatment technique violation, as specified
in subsection (h)(2), shall be placed on monthly monitoring for a minimum of
one year beginning in the next month in which the supplier provides water to
the public. After 12 consecutive months of monitoring, the Department may
allow the water system to return to quarterly monitoring in accordance with
subsection (b)(1)(A).
E) A supplier
may return to quarterly monitoring after being triggered to monthly monitoring
under subsection (b)(1)(C), once all of the following criteria are met:
i) The
system is free of sanitary defects, has a protected source, and the wells
conform to the requirements of the Water Well Construction Code;
ii) The
on-site assessment and all corrective actions specified by the Department have
been completed;
iii) The
system has conducted any increased monitoring required by the Department; and
iv) The system is in compliance with cross-connection
requirements in Section 900.40(l).
2) Repeat
Monitoring
A) If a
sample taken under subsection (b)(1) or (b)(4) is total coliform-positive, the
supplier must collect a set of repeat samples within 24 hours after being
notified of the positive result. The supplier must collect no fewer than three
repeat samples for each total coliform-positive sample found. The Department
will extend the 24- hour limit if the supplier has a logistical problem in
collecting the repeat samples within 24 hours that is beyond its control. The
Department will not waive the requirement for a supplier to collect the repeat
samples described in subsections (b)(2)(A) through (C).
B) The
supplier must collect all repeat samples on the same day, except the Department
will allow a supplier with a single service connection to collect the required
set of repeat samples over a three-day period or to collect a larger volume of
repeat samples in one or more sample containers of any size, as long as the
total volume collected is at least 300 milliliters.
C) The
supplier must collect an additional set of repeat samples in the manner
specified in subsections (b)(2)(A) through (C) if one or more repeat samples in
the current set of repeat samples is total coliform-positive. The supplier
must collect the additional set of repeat samples within 24 hours after being
notified of the positive result, unless the Department extends the limit as
provided in subsection (b)(2)(A). The supplier must continue to collect
additional sets of repeat samples until either total coliforms are not detected
in one complete set of repeat samples or the supplier determines that a
coliform treatment technique trigger specified in subsection (d) has been
exceeded as a result of a repeat sample being total coliform-positive and
notifies the Department. If a trigger identified in subsection (d) is exceeded
as a result of a routine sample being total coliform-positive, the supplier is
required to conduct only one round of repeat monitoring for each total
coliform-positive routine sample.
D) After
a supplier collects a routine sample and before it learns the results of the
analysis of that sample, if the supplier collects another routine sample from
within five adjacent service connections of the initial sample, and the initial
sample, after analysis, is found to contain total coliforms, then the supplier
may count the subsequent sample as a repeat sample instead of as a routine
sample.
E) Results
of all routine and repeat samples taken under subsection (b) not invalidated by
the Department must be used to determine whether a coliform treatment technique
trigger specified in subsection (d) has been exceeded.
3) Escherichia
coli (E. coli) Testing
A) If any
routine or repeat sample is total coliform-positive, the supplier's certified
laboratory must analyze that total coliform-positive culture medium to
determine if E. coli are present. If E. coli are present, the supplier must
notify the Department by the end of the day when the supplier is notified of
the test result. If the supplier is notified of the result after the Department
office is closed and the Department does not have either an after-hours phone
line or an alternative notification procedure, the supplier must notify the
Department before the end of the next business day.
B) The
Department will allow a supplier to forego E. coli testing on a total
coliform-positive sample if that supplier assumes that the total
coliform-positive sample is E. coli-positive. Accordingly, the supplier must
notify the Department as specified in subsection (b)(3)(A) and must notify the
public in accordance with 35 Ill. Adm. Code 611.Subpart V.
4) Additional
Routine Monitoring the Month Following a Total Coliform-Positive Sample
A) Except
as provided in subsection (b)(4)(D), a supplier conducting monitoring pursuant
to subsection (b)(1)(A) must collect at least three routine samples during the
month following a total coliform-positive sample.
B) The
supplier shall either collect samples at regular time intervals throughout the
month or shall collect all required routine samples on a single day if samples
are taken from different sites.
C) The
supplier must use the results of additional routine samples in coliform
treatment technique trigger calculations under subsection (d).
D) Waiver.
Except as provided in subsection (b)(4)(F), the Department will waive the
requirement to collect three routine samples the next
month in which the supplier provides water to the public if:
i) The
Department performs a site visit before the end of the next month in which the
supplier provides water to the public. Although a sanitary survey is not
required, the site visit must be sufficiently detailed to allow the Department
to determine whether additional monitoring or any corrective action is needed;
ii) The
Department determines why the sample was total coliform-positive and
establishes that the supplier has corrected the problem or will correct the
problem before the end of the next month in which the supplier serves water to
the public; or
iii) The
Department determines that the supplier has corrected the contamination problem
before the supplier takes the set of repeat samples required in subsection
(b)(2) and all repeat samples were total coliform-negative.
E) The
Department must document any decision to waive the additional monitoring
requirements in writing, have it approved and signed by the supervisor of the
Department official who recommends that decision, and make this document
available to USEPA and the public. The written documentation must describe the
specific cause of the total coliform-positive sample and what action the
supplier has taken or will take to correct this problem.
F) Any
supplier that fails to collect all required repeat samples following any total coliform-positive
sample must collect three routine samples the next month in which the supplier
provides water to the public.
5) Sample
Siting Plans. A supplier must develop a written sample siting plan that
identifies sampling sites and a sample collection schedule that are
representative of water throughout the distribution system. These plans are
subject to Department review and revision. The supplier must collect total
coliform samples according to the sample siting plan. Routine and repeat
sample sites and any raw water sampling sites necessary to conduct triggered
source water monitoring must be reflected in the sampling plan.
c) All
seasonal non-community public water system suppliers must demonstrate
completion of a Department-approved start-up procedure, which shall include a
requirement for startup sampling to demonstrate coliform bacteria is not
present prior to serving water to the public. This demonstration must be
certified by the supplier on a form provided by the Department and submitted to
the Department prior to serving water to the public. This requirement may be
waived for seasonal systems if the entire distribution system remains
pressurized during the entire period that the system is not operating. In
addition to the start-up sampling, seasonal systems must have an approved
sample siting plan that designates the time period for monitoring based on site-specific
considerations (e.g., during periods of highest demand or highest vulnerability
to contamination). Seasonal suppliers must collect compliance samples during
this time period.
d) Coliform
Treatment Technique Triggers. A supplier must conduct assessments in
accordance with subsection (e) after exceeding treatment technique triggers in
subsection (d)(1) or (d)(2).
1) Monitoring Assessment Triggers
A) The
supplier fails to take a routine sample as required in subsection (b)(1)(A).
B) The
supplier fails to take every required repeat sample after any single total
coliform-positive sample, as required in subsection (b)(2).
C) The supplier
fails to take additional routine monitoring samples as required in subsection
(b)(4).
2) On-site
Assessment Triggers
A) An E.
coli MCL violation, as specified in subsection (h)(1).
B) A
system has two or more total coliform-positive samples in the same month.
e) Requirements
for Assessments
1) A
supplier must ensure that monitoring assessments are conducted in order to
identify the cause of the monitoring violation and to institute procedures to
prevent future monitoring violations.
2) A
supplier must ensure that on-site assessments are conducted in order to
identify the possible presence of sanitary defects and defects in distribution
system coliform monitoring practices. On-site assessments must be conducted by
the Department or parties approved by the Department.
3) When
conducting on-site assessments, the supplier must ensure that the assessor
evaluates minimum elements that include review and identification of
inadequacies in sample sites; sampling protocol; sample processing; atypical
events that could affect distributed water quality or indicate that distributed
water quality was impaired; changes in distribution system maintenance and
operation that could affect distributed water quality (including water
storage); source and treatment considerations that bear on distributed water
quality, where appropriate (e.g., small ground water systems); and existing
water quality monitoring data. The supplier must conduct the assessment
consistent with specific assessment elements with respect to the size and type
of the system and the size, type, and characteristics of the distribution
system.
4) Monitoring
Assessments. A supplier shall obtain a monitoring assessment if the water
system exceeds one of the treatment technique triggers in subsection (d)(1).
A) The
supplier must complete a monitoring assessment as soon as practical after any
trigger in subsection (d)(1). In the completed assessment form, the supplier
must describe corrective actions completed, and a proposed timetable for any
corrective actions not already completed. The supplier must submit the
completed monitoring assessment form to the Department within 30 days after the
supplier learns that it has exceeded a trigger.
B) If the
Department reviews the completed monitoring assessment and determines that the
assessment is not sufficient (including any proposed timetable for any
corrective actions not already completed), the Department must consult with the
supplier. If the Department requires revisions after consultation, the
supplier must submit a revised assessment form to the Department on an
agreed-upon schedule not to exceed 30 days after the date of the consultation.
C) Upon
completion and submission of the assessment form by the supplier, the
Department must determine if the supplier has identified a likely cause for the
monitoring assessment trigger and, if so, establish that the supplier has
corrected the problem, or has included a schedule acceptable to the Department
for correcting the problem.
D) Monitoring
assessments must include submittal of replacement samples for all missed
samples that caused a monitoring assessment trigger to be exceeded.
E) Monitoring
Assessments do not require an on-site visit and may be conducted by telephone
or electronic correspondence.
5) On-site
Assessments. A supplier shall obtain an on-site assessment if the water system
exceeds one of the treatment technique triggers in subsection (d)(2). The
supplier must comply with any expedited actions or additional actions required
by the Department in the case of an E. coli MCL violation.
A) The
supplier must ensure that an on-site assessment is completed by the Department
or by a third party approved by the Department as soon as practical after any
trigger in subsection (d)(2). The supplier must submit a completed on-site
assessment form to the Department within 30 days after the supplier learns that
it has exceeded a trigger. The assessment form must describe sanitary defects
detected, corrective actions completed, and a proposed timetable for any
corrective actions not already completed. The assessment form may also note
that no sanitary defects were identified.
B) If the
Department reviews the completed on-site assessment and determines that the
assessment is not sufficient (including any proposed timetable for any
corrective actions not already completed), the Department must consult with the
supplier. If the Department requires revisions after consultation, the
supplier must submit a revised assessment form to the Department on an
agreed-upon schedule not to exceed 30 days.
C) Upon
completion and submission of the assessment form by the supplier, the
Department must determine if a definitive cause for the on-site trigger has
been identified and determine whether the supplier has corrected the problem or
has included a schedule acceptable to the Department for correcting the
problem.
D) On-site
assessments must include clearance samples and submittal of replacement samples
for all missed routine, repeat and additional routine samples.
f) Corrective
Action. A supplier must correct sanitary defects found through either
monitoring or on-site assessments conducted under subsection (e). For
corrections not completed by the time of submission of the assessment form, the
supplier must complete the corrective actions in compliance with a timetable
approved by the Department in consultation with the supplier. The supplier
must notify the Department when each scheduled corrective action is completed.
g) Consultation.
At any time during the assessment or corrective action phase, either the
supplier or the Department may request a consultation with the other party to
determine the appropriate actions to be taken. The supplier may consult with
the Department on all relevant information that may impact on its ability to
comply with a requirement of this Section, including the method of
accomplishment, an appropriate timeframe, and other relevant information.
h) Violations
1) E.
coli MCL Violations. A supplier is in violation of the MCL for E. coli when
any of the conditions identified in this subsection (h)(1) occur.

supplier has a total coliform-positive repeat sample following an E.
coli-positive routine sample.
C) The
supplier fails to take all required repeat samples following an E.
coli-positive routine sample.
D) The
supplier fails to test for E. coli when any repeat sample tests positive for
total coliform.
2) Treatment
Technique Violation
A) A
treatment technique violation occurs when a supplier exceeds a treatment
technique trigger specified in subsection (d) and then fails to complete the
required assessment or corrective actions, including the collection of all
required samples in accordance with subsections (d)(1) and (d)(2), within the
timeframe specified in subsections (e) and (f).
B) A
treatment technique violation occurs when a seasonal supplier fails to complete
a Department-approved start-up procedure prior to serving water to the public.
3) Monitoring
Violations
A) Failure
to take every required routine or additional routine sample in a compliance
period is a monitoring violation.
B) Failure
to analyze for E. coli following a total coliform-positive routine sample is a
monitoring violation.
4) Reporting Violations
A) Failure
to submit a monitoring report or completed assessment form after a supplier
properly conducts monitoring or assessment in a timely manner is a reporting
violation.
B) Failure
to notify the Department following an E. coli-positive sample as required by
subsection (b)(3)(A) in a timely manner is a reporting violation.
C) Failure
to submit certification of completion of Department-approved start-up procedure
by a seasonal supplier is a reporting violation.
i) Reporting
1) E. coli
A) A
supplier must notify the Department by the end of the day when the system
learns of an E. coli MCL violation. If the supplier learns of the violation
after the Department office is closed and the Department does not have either
an after-hours phone line or an alternative notification procedure, the
supplier must notify the Department before the end of the next business day.
The supplier must also notify the public in accordance with 35 Ill. Adm. Code 611.Subpart
V.
B) A
supplier must notify the Department by the end of the day when the supplier is

TITLE 77: PUBLIC HEALTH
CHAPTER I: DEPARTMENT OF PUBLIC HEALTH
SUBCHAPTER r: WATER AND SEWAGE
PART 900
DRINKING WATER SYSTEMS CODE
SECTION 900.40 WATER SYSTEM DESIGN
Section 900.40 Water System
Design
a) Siting Requirements. Construction, alteration or expansion of
a public water system shall be accomplished so as to:
1) Avoid locating any or all of the facility at a site that is
subject to undue risk from earthquakes, floods, or other disasters.
2) Except for the intake structures, avoid locating any or all of
the facility within the floodplain of a 100-year flood.
3) Sources of pollution shall be located no closer to wells and
finished water storage facilities than indicated in Table A. Beginning January
1, 1988, no new non-community water system well may be located within 200 feet
of any potential primary or potential secondary source or any potential route,
unless specifically allowed in Table A. When the owner of a potable well is
the same owner of a potential primary source, potential secondary source, or a
potential route, the Department may allow a variance to the minimum separation
distances required in this Part provided the owner complies with the variance
provisions of Section 920.30(c) of the Water Well Construction Code.
b) Existing Water System. The sanitary quality of an existing
water system shall be determined by a survey of facilities and laboratory
analyses of water samples. Defects in facilities or contamination shown
present by laboratory analyses shall be considered sufficient grounds for
requiring repairs, chlorination or other treatment, or termination of the use
of the system. All repairs, modifications, and alterations to existing wells
and pump equipment shall be in accordance with the Water Well Construction
Code, the Illinois Plumbing Code, and the Illinois Water Well Pump Installation
Code. Treatment will not be considered a substitute for location and
construction in accordance with the Water Well Construction Code. Wells
terminating in pits shall not be allowed. Existing pits shall be eliminated
and the floor or one wall of the pit shall be broken or removed, the pit shall
be filled with compacted earth, and the casing shall be extended to terminate 8
inches above grade.
c) New Well Construction. All new wells shall be constructed in
accordance with the Water Well Construction Code.
d) New Pumping Equipment. All new well pumps shall be installed
in conformance with the Illinois Water Well Pump Installation Code.
e) Surface Water. Gravity filtration and disinfection shall be
provided as the minimum treatment facilities for all supplies obtained from
ponds, lakes, streams, rivers, groundwater under the influence of surface
water, and other surface collectors of water. Surface water supply treatment
facilities shall be designed, constructed, operated, and maintained as
described in the Surface Source Water Treatment Code or in accordance with the
Ten States' Standards. Where average turbidity, based upon 30 daily samples,
of the source exceeds 50 nephelometric turbidity units, complete treatment must
be provided in accordance with the Ten States' Standards. All systems that use
surface water, in whole or in part shall be operated by personnel who have
taken a water treatment course approved by the Department and have received a
certificate or other evidence that the course has been completed satisfactorily
(such as a letter from the school), or shall be operated by personnel that have
received certification from the Illinois Environmental Protection Agency as a
Class A or Class B public water supply operator. The Department will approve a
course if the course is given by an accredited college or university, is at
least equivalent to .7 continuing education units, and addresses water
filtration, disinfection, water supply, and the measurement of disinfectant
residual and turbidity. The Department will make available a list of approved
courses upon request.
f) Springs. Spring water supplies shall not be allowed except
where it is impossible to develop a well that meets the water quality and
capacity standards of this Part. Where springs are used for potable water,
they shall be protected from entry of surface water, housed in a permanent
structure, and chlorinated in accordance with subsection (n). Spring water
supplies located in an area with sink-holes or outcropping rock, with a history
of periodic discolored discharge, or subject to fecal contamination, as
demonstrated by laboratory analysis, shall not be approved unless provided with
treatment consistent with that required for surface water.
g) Cisterns. Cisterns shall not be used for public water supply
except where groundwater resources will not produce the quantity of water
needed for the population to be served. Cistern water shall receive treatment
consistent with that required for surface water (see subsection (e)).
h) Design Capacity. The design capacity for a non-community
public water system shall be determined based on the estimated peak demand or
the average daily consumption rate obtained from Table B.
i) Hydropneumatic Storage. The minimum requirements for designing
a hydropneumatic storage system are as follows:
1) Well and Pump Sizing. The capacity of the wells and pumps in
a hydropneumatic system shall be at least eight times the average daily
consumption rate or shall be sufficient to meet the estimated peak demand,
whichever is greater. (Calculate the average daily consumption rate from Table
B). If it can be shown that a specified amount of water is more appropriate,
or if the Department can be shown that the storage requirements are excessive,
the Department will permit other sizing alternatives dependent upon, but not
limited to, water demand at the facility in question or water usage reports
from a similar facility.
2) Pressure Tank Sizing. The minimum capacity of the pressure
storage tank shall be calculated by the following formula:
Q =
Qm(3)/Pf
Where:
QM = Pump
capacity (g.p.m.)
Pf = Pressure
factor obtained from TABLE C.
3) Precharged Pressure Tanks. The capacity of a precharge
pressure storage tank shall be calculated by the following formula:
Qp = 1.50m/Pf
Where:
Qp = Precharged
pressure tank volume, gal.
4) Existing Hydropneumatic Storage. An existing undersized
pressure storage system may be allowed provided a history of adequate water
supply exists. Major alterations shall comply with all requirements of subsection
(i).
j) Storage Reservoir. All nonpressure underground reservoirs
shall be constructed of permanently watertight material and shall be provided
with a watertight insect-proof cover. Examples of permanently watertight
materials are steel, plastic, concrete or fiberglass. On new water system installations,
all nonpressure storage reservoirs in or on the ground shall be located in such
a manner that surface water will flow away from the structure. When the bottom
of any such reservoir is located below the ground surface, the reservoir shall be
located with respect to sources of pollution as outlined in Table A. Where
manholes are necessary, they shall have a raised curb and be provided with a
cover of the overhanging type. Vents and openings shall be insect-proof and
shall be installed so there is no hazard to the sanitary quality of the water
supply. Piping shall enter the reservoir through the top of underground tanks
or through the exposed vertical extension of the manhole opening. Points of
entry must be sealed in a watertight manner. No suction lines may enter the
reservoir underground unless protected by an external pipe enclosure maintained
at system pressure.
k) Water Distribution Lines. The system shall be designed to
maintain a minimum positive pressure of 20 p.s.i. in all parts of the system at
all times. Water pipe shall conform to applicable specifications and standards
of the Illinois Plumbing Code for the type of pipe to be used. The following
shall govern the separation of water lines from possible sources of pollution:
1) Whenever possible, a water line shall be laid at least 10 feet
horizontally from any existing or proposed sewer line.
2) Whenever water lines must cross sewers, the water line shall
be laid at such an elevation that the bottom of the water line is 18 inches
above the top of the sewer. This vertical separation shall be maintained for
that portion of the water line located within 10 feet horizontally of any sewer
or drain it crosses, with the 10 feet to be measured as the normal distance
from the water line to the drain or sewer. The sewer shall be constructed of
cast iron pipe, type K copper, or Drain, Waste and Vent (DWV) plastic pipe
(Schedule 40) with water-tight joints for a distance of 10 feet from each side
of the water line. All crossings shall be made at right angles.
3) Where conditions prevent the minimum horizontal and/or
vertical separation specified in subsections (k)(1) and (2), special
consultation shall be obtained from the Department to determine other routes of
water piping. In all cases, construction shall meet the applicable provisions
of Section 1150 of the Illinois Plumbing Code.
4) No water line shall pass through, or come into contact with,
any part of a sewer manhole.
5) There shall be no physical connection between a community
water system and a non-community or private water system, unless the
non-community or private water system is in compliance with cross-connection
requirements in subsection (l).
6) Lines for potable water shall be laid at least 25 feet
horizontally from any underground sewage seepage field.
1) Plumbing Fixture Backflow Protection. The water supply lines
shall have no physical connection with nonpotable water supplies. All plumbing
shall be in accord with the Illinois Plumbing Code. All plumbing fixtures and
other equipment connected to the water system shall be constructed and
installed to safeguard the water system from the possibility of contamination
through cross-connections or backsiphonage. Laundry units and equipment shall
be so constructed and installed to prevent the contamination of the contents by
the backflow of sewage. When required by the Illinois Plumbing Code, the
fixture or appliance shall be connected indirectly with the drainage system by
means of an open, funnel-type fitting with a suitable air gap.
m) Drinking Fountains. All outlets established for the provision
of drinking water shall consist of drinking fountains in accordance with
requirements contained in the Illinois Plumbing Code, or a supply of single
service drinking cups shall be provided. Common drinking cups are prohibited.
n) Disinfection. Disinfection may be accomplished with calcium
or sodium hypochlorites or gas chlorine. Other disinfecting agents will be
considered, providing reliable application equipment is available, and testing
procedures for residual are recognized in "Standard Methods for the Examination
of Water and Wastewater". Proposals for use of disinfecting agents must
be approved by the Department prior to preparation of final plans and
specifications. Approval will be given only when the information shows that
the chemical to be used as a disinfecting agent will not jeopardize the health
of the user and that the chemical will eliminate bacteria from the water
supply. Disinfection is required at all surface, spring, and cistern water
supplies; and at any groundwater supplies that are of questionable sanitary
quality or where any treatment that exposes the water to the atmosphere is
provided. Disinfection shall not be a substitute for proper well location and
construction.
1) Chlorination Equipment. The chlorinator shall be designed to
provide a free chlorine residual of at least 2 milligrams per liter in the
water after contact time of at least 30 minutes at maximum flow rates. The
equipment shall be of such design that it will operate accurately over the
desired feeding range. Where flow is uniform, actuation of a constant volume
feeder by the pump circuit is required. Where flow is variable, automatic flow
proportioning is required.
2) Contact Time and Point of Application. Chlorine shall be
applied at a point that will provide the maximum contact time. At facilities
treating surface water, chlorine shall be applied to the water after
filtration. At facilities chlorinating groundwater, provisions should be made
for applying chlorine to the detention basin inlet. When chlorination is required,
minimum free chlorine residual at distant points in a water distribution system
shall be at least 0.1 milligram per liter, except that systems utilizing
surface water as a source shall have a minimum free chlorine residual of 0.2
mg/l maintained at all distant points in the distribution system and a minimum
free chlorine residual of 0.4 mg/l shall maintained in the water storage tank.
Those systems utilizing surface water as a source and groundwater under the
influence of surface water shall be designed in accordance with the Surface
Water Treatment Code and shall meet disinfection requirements and CT values of
40 CFR 141.
3) Testing Equipment. Chlorine residual test equipment capable
of measuring free chlorine residual shall be provided and should be capable of

source of public supply, the water shall be obtained only from a regulated
public water system.
1) Transport Equipment. Equipment used for hauling water,
including tank trucks or trailers, hoses, etc., shall be used only for handling
potable water. In an emergency, equipment used for handling other potable
materials, such as milk, syrup, etc., may be used after cleaning and
disinfection with not less than 100 ppm of free chlorine.
2) Storage Facilities. Equipment used for the storage of hauled water
shall be used only for that purpose and shall be constructed in accordance with
subsection (j). A minimum free chlorine residual of 0.4 mg/l shall be
maintained in the water storage tank.
p) Vending Machines. Vending machines that serve water to the
public shall meet the following conditions:
1) The source of water to a vending machine shall be obtained
from a community water system or a supply that meets the construction and
location requirements of this Part.
2) A dual check backflow device approved in accordance with the
Illinois Plumbing Code shall be installed in the water supply pipe between the
vending machine and the source of water.
3) An air gap shall be provided between the water dispensing
spout and the water container that is at least equal to 4 times the diameter of
the water dispensing supply pipe.
4) The machine shall be kept in an area that is free of dirt and
debris. The area shall be maintained to prevent insect and rodent harborage.
5) Any overflow or discharge of water from the vending machine
shall be indirectly connected to a sewer or to waste in accordance with the
Illinois Plumbing Code.
q) Sample Siting Plan. All non-community supplies shall
designate sampling points from which to collect all required samples. If a
kitchen tap is available, one sample shall be taken from this location.

directly supervised and operated by personnel who:
1) are currently the operator in responsible charge of the
non-transient, non-community public water system and whose identity has been
submitted to the Department by the non-transient, non-community public water
supply system by January 1, 2000; or
2) have been certified by the Department; or
3) have been certified as a public water supply operator by the
Illinois Environmental Protection Agency.
b) Operator Certification.
1) All operators must be certified by January 1, 2003. In order
to be certified by the Department, an operator must provide evidence of
successful completion of a water operator's course that has been approved by the
Department. Successful completion shall mean passing a written examination
given at the end of the training. Evidence of completion shall be a letter
from the school or approved training organization conducting the course. Upon
receipt of this documentation, the Department will provide a certificate to the
operator.
2) All courses and training organizations must be approved by the
Department. The course must consist of at least 12 hours of classroom
instruction addressing disinfection and measurement of disinfectant residual,
treatment, sample collection, water wells, Department regulations and small
water system operation. The examination administered at the conclusion of the
training course will be based on job performance.
3) Operator training courses must be updated and approved
annually by the Department to ensure that all current regulations are covered
in the training course.
4) Applicants for the training course must provide to the
training organization evidence of having a high school diploma or the
equivalent, or must be currently employed by a non-transient, non-community
public water system.
5) Certified operators shall be recertified every three years.
In order to be recertified, the operator shall attend a recertification
training session approved by the Department and provide proof of attendance
from the organization conducting the course. The recertification training
shall provide information on new USEPA drinking water regulations, new
technology, and water treatment topics that will aid the operator in the
