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.

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.
