Proposed Rule. Proposal for Public Comment.
ORDER OF THE BOARD (by R.C. Flemal):
Under Sections 7.2 and 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and 17.5 (1998)), the Board proposes amendments to the Illinois regulations that are “identical in substance” to drinking water regulations that the United States Environmental Protection Agency (USEPA) adopted to implement Sections 1412(b), 1414(c), 1417(a), and 1445(a) of the federal Safe Drinking Water Act (SDWA) (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and 300j-4(a) (1998)). The nominal timeframe of this docket includes federal SDWA amendments that USEPA adopted in the period January 1, 2000, through June 30, 2000.
Sections 7.2 and 17.5 provide for quick adoption of regulations that are identical in substance to federal regulations that USEPA adopts to implement Sections 1412(b), 1414(c), 1417(a), and 1445(a) of the federal Safe Drinking Water Act (SDWA) (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and 300j-4(a) (1998)). Section 17.5 also provides that Title VII of the Act and Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-35 and 5-40 (1998)) do not apply to the Board’s adoption of identical-in-substance regulations. The federal SDWA regulations are found at 40 C.F.R. 141 through 143.
This proposed order is supported by a proposed opinion that the Board also adopts today. The Board will cause the proposed amendments to be published in the Illinois Register and will receive public comments for 45 days after the date of publication.
IT IS SO ORDERED.
I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, do hereby certify that the above order was adopted on the 5th day of October 2000 by a vote of 7-0.

| Section 611.131 | Relief Equivalent to SDWA Section 1415(e) Small System Variance |
This Section is intended as a State equivalent of Section 1415(e) of the federal SDWA (42 USC 300g-1).
| a) | Variances may be obtained from the requirement to comply with an MCL or treatment technique to a PWS serving fewer than 10,000 persons in this Section. The PWS |
| b) | The Board will grant a small system variance to a PWS serving fewer than 3,300 persons. The Board will grant a small system variance to a PWS serving more than 3,300 persons but fewer than 10,000 persons with the approval of the USEPA. In determining the number of persons served by the PWS, the Board will include persons served by consecutive systems. A small system variance granted to a PWS also applies to any consecutive system served by it. |
| c) | Availability of a variance. |
| 1) | A small system variance is not available under this Section for an NPDWR for a microbial contaminant (including a bacterium, virus, or other organism) or an indicator or treatment technique for a microbial contaminant. |
| 2) | A small system variance under this Section is available for compliance with a requirement specifying an MCL or treatment technique for a contaminant with respect to which the following is true: |
| A) | An NPDWR was promulgated on or after January 1, 1986; and |
| B) | The USEPA has published a small system variance technology pursuant to Section 1412(b)(15) of the federal SDWA (42 USC 300g-1(b)(15)). |
BOARD NOTE: Small system variances are not available for PWSs above the pre - 1986 MCL even if subsequently revised. If the USEPA revises a pre - 1986 MCL and makes it more stringent, then a variance would be available for that contaminant, but only up to the pre - 1986 pre-1986 maximum contaminant level.
| d) | No small system variance will be in effect until the later of the following: |
| 1) | 90 days after the Board proposes to grant the small system variance; |
| 2) | If the Board is proposing to grant a small system variance to a PWS serving fewer than 3,300 persons and the USEPA objects to the small system variance, the date on which the Board makes the recommended modifications or responds in writing to each objection; or |
| 3) | If the Board is proposing to grant a small system variance to a PWS serving a population of more than 3,300 and fewer than 10,000 persons, the date the USEPA approves the small system variance. |
| e) | As part of the showing of arbitrary or unreasonable hardship, the PWS |
| 1) | |
| 2) | |
| A) | Treatment; |
| B) | Alternative sources of water supply; |
| C) | Restructuring or consolidation changes, including ownership change or physical consolidation with another PWS; or |
| D) | Obtaining financial assistance pursuant to Section 1452 of the federal SDWA or any other federal or State program; |
| 3) | |
| 4) | |
| 5) | |
| A) | The quality of the source water for the PWS; and |
| B) | Removal efficiencies and expected useful life of the small system variance technology. |
| f) | Terms and Conditions. |
| 1) | The Board will set the terms and conditions of a small system variance issued under this Section and will include, at a minimum, the following requirements: |
| A) | Proper and effective installation, operation, and maintenance of the applicable small system variance technology in accordance with guidance published by the USEPA, taking into consideration any relevant source water characteristics and any other site-specific conditions that may affect proper and effective operation and maintenance of the technology; |
| B) | Monitoring requirements, for the contaminant for which a small system variance is sought; and |
| C) | Any other terms or conditions that are necessary to ensure adequate protection of public health, which may include: |
i) Public education requirements; and
ii) Source water protection requirements.
| 2) | The Board will establish a schedule for the PWS to comply with the terms and conditions of the small system variance that will include, at a minimum, the following requirements: |
| A) | Increments of progress, such as milestone dates for the PWS to apply for financial assistance and begin capital improvements; |
| B) | Quarterly reporting to the Agency of the PWSs compliance with the terms and conditions of the small system variance; |
| C) | Schedule for the Board to review the small system variance; and |
BOARD NOTE: Corresponding 40 CFR 142.307(d) (1999) provides that the states must review variances no less frequently than every five years. Section 36 of the Act provides that 5 years is the maximum terms of a variance.
| D) | Compliance with the terms and conditions of the small system variance as soon as practicable, but not later than three years after the date on which the small system variance is granted. The Board may allow up to two additional years if the Board determines that additional time is necessary for the PWS to: |
| i) | Complete necessary capital improvements to comply with the small system variance technology, secure an alternative source of water, or restructure or consolidate; or |
| ii) | Obtain financial assistance provided pursuant to Section 1452 of the SDWA or any other federal or State program. |
| g) | The Board will provide notice and opportunity for a public hearing as provided in 35 Ill. Adm. Code 104, except as modified or supplemented by this Section. |
| 1) | At least 30 days before the public hearing to discuss the proposed small system variance, the PWS |
| A) | Direct mail or other home delivery to billed customers or other service connections, and |
| B) | Any other method reasonably calculated to notify, in a brief and concise manner, other persons regularly served by the PWS. Such methods may include publication in a local newspaper, posting in public places or delivery to community organizations. |
| 2) | The notice in subsection (g)(1)(A) of this Section must include, at a minimum, the following: |
| A) | Identification of the contaminant(s) for which a small system variance is sought; |
| B) | A brief statement of the health effects associated with the contaminant(s) for which a small system variance is sought using language in Appendix |
| C) | The address and telephone number at which interested persons may obtain further information concerning the contaminant and the small system variance; |
| D) | A brief summary, in easily understandable terms, of the terms and conditions of the small system variance; |
| E) | A description of the consumer petition process under subsection (h) of this Section and information on contacting the USEPA Regional Office; |
| F) | A brief statement announcing the public meeting required under subsection (g)(3) of this Section, including a statement of the purpose of the meeting, information regarding the time and location for the meeting, and the address and telephone number at which interested persons may obtain further information concerning the meeting; and |
| G) | In communities with a large proportion of non-English-speaking residents, as determined by the Board, information in the appropriate language regarding the content and importance of the notice. |
| 3) | The Board will provide for at least one public hearing on the small system variance. The PWS |
| 4) | Prior to promulgating the final variance, the Board will respond in writing to all significant public comments received relating to the small system variance. Response to public comment and any other documentation supporting the issuance of a variance will be made available to the public after final promulgation. |
| h) | Any person served by the PWS may petition the USEPA to object to the granting of a small system variance within 30 days after the Board proposes to grant a small system variance for the PWS. |
| i) | The Agency |
| j) | In addition to the requirements of this Section, the provisions of Section 611.111, 611.112, or 611.130 may apply to relief granted pursuant to this Section. |

| 2) | If a supplier is in violation of Section 611.351 or Section 611.353 for failure to install source water or corrosion control treatment, the Agency may, by a SEP issued pursuant to Section 611.110, require the supplier to commence lead service line replacement under this Section after the date by which the supplier was required to conduct monitoring under Section 611.356(d)(2) has passed. |
b) Annual replacement of lead service lines.
| 1) | A supplier required to commence lead service line replacement pursuant to subsection (a) |
| 2) | The initial number of lead service lines is the number of lead lines in place at the time the replacement program begins. |
| 3) | The supplier |
| 4) | The first year of lead service line replacement |
| c) | Service lines not needing replacement. A supplier is not required to replace any individual lead service line for which the lead concentrations in all service line samples taken from that line pursuant to Section 611.356(b)(3) are less than or equal to 0.015 mg/L. |
| d) | A water supplier must replace that portion of the lead service line that it owns. In cases where the supplier does not own the entire lead service line, the supplier must notify the owner of the line, or the owner’s authorized agent, that the supplier will replace the portion of the service line that it owns and must offer to replace the owner’s portion of the line. A supplier is not required to bear the cost of replacing the privately-owned portion of the line, nor is it required to replace the privately-owned portion where the owner chooses not to pay the cost of replacing the privately-owned portion of the line, or where replacing the privately-owned portion would be precluded by State, local or common law. A water supplier that does not replace the entire length of the service line also must complete the following tasks: |
| 1) | Notice Prior to Commencement of Work. |
| A) | At least 45 days prior to commencing the partial replacement of a lead service line, the water supplier must provide notice to the residents of all buildings served by the line explaining that they may experience a temporary increase of lead levels in their drinking water, along with guidance on measures consumers can take to minimize their exposure to lead. |
| B) | The Agency, by issuing an appropriate SEP, may allow the water supplier to provide notice under the previous sentence less than 45 days prior to commencing partial lead service line replacement where it determines that such replacement is in conjunction with emergency repairs. |
| C) | In addition, the water supplier must inform the residents served by the line that the supplier will, at the supplier’s expense, collect a sample from each partially-replaced lead service line that is representative of the water in the service line for analysis of lead content, as prescribed by Section 611.356(b)(3), within 72 hours after the completion of the partial replacement of the service line. The supplier must collect the sample and report the results of the analysis to the owner and the residents served by the line within three business days of receiving the results. |
| D) | Mailed notices post-marked within three business days of receiving the results must be considered “on time.” |
| 2) | The water supplier must provide the information required by subsection (d)(1) of this Section to the residents of individual dwellings by mail or by other methods approved by the Agency by a SEP issued pursuant to Section 611.110. In instances where multi-family dwellings are served by the service line, the water supplier must have the option to post the information at a conspicuous location. |
e) Control of entire service line.
BOARD NOTE: See Section 611.360(e)(4) and the Board Note that follows. The court in American Water Works Association v. EPA, 40 F.3d 1266 (D.C. Cir. 1994), vacated U.S. EPA’s definition of “control” to the extent it would require the supplier to exert “control” over a privately-owned service connection.

| Resumption of standard monitoring. | |
| i) | Small or medium-sized suppliers exceeding lead or copper action level. A small or medium-sized system supplier subject to reduced monitoring that exceeds the lead action level or the copper action level |
| ii) | Suppliers failing to operate within water quality control parameters. Any supplier subject to reduced monitoring frequency that fails to operate within the range of values for the water quality control parameters specified pursuant to Section 611.352(f) for more than nine days in any six-month period specified in Section 611.357(d) |
| G) | Any water supplier subject to a reduced monitoring frequency under subsection (d)(4) of this Section that either adds a new source of water or changes any water treatment must inform the Agency in writing in accordance with Section 611.360(a)(3). The Agency may, by a SEP granted pursuant to Section 611.110, require the system to resume sampling in accordance with subsection (d)(3) of this Section and collect the number of samples specified for standard monitoring under subsection (c) of this Section or take other appropriate steps such as increased water quality parameter monitoring or re-evaluation of its corrosion control treatment given the potentially different water quality considerations. |
| H) | A supplier required under subsection (f)(4)(F) of this Section to resume monitoring in accordance with Section 611.357(d) may resume reduced monitoring for lead and copper at the tap and for water quality parameters within the distribution system under the following conditions: |
| i) | The supplier may resume annual monitoring for lead and copper at the tap at the reduced number of sites specified in subsection (c) of this Section after it has completed two subsequent six-month rounds of monitoring that meet the criteria of subsection (d)(4)(B) of this Section and the supplier has received written approval from the Agency by a SEP pursuant to Section 611.110 that it is appropriate to resume reduced monitoring on an annual frequency. |
| ii) | The supplier may resume monitoring for lead and copper once every three years at the tap at the reduced number of sites after it demonstrates through subsequent rounds of monitoring that it meets the criteria of either subsection (d)(4)(C) or (d)(4)(E) of this Section and the system has received a SEP under Section 611.110 from the Agency that it is appropriate to resume monitoring once every three years. |
| iii) | The supplier may reduce the number of water quality parameter tap water samples required in accordance with Section 611.357(e)(1) and the frequency with which it collects such samples in accordance with Section 611.357(e)(2). Such a system may not resume monitoring once every three years for water quality parameters at the tap until it demonstrates, in accordance with the requirements of Section 611.357(e)(2), that it has re-qualified for monitoring once every three years. |
BOARD NOTE: Subsections (d)(4)(H)(i) through (d)(4)(H)(iii) are derived from 40 C.F.R. 141.86(d)(4)(vi)(B)(1) through (d)(4)(vi)(B)(3), as added at 65 Fed. Reg. 2009 (January 12, 2000), since Illinois Administrative Code codification requirements allow only four indent levels of subsections.
| e) | Additional monitoring. The results of any monitoring conducted in addition to the minimum requirements of this section |
| f) | Invalidation of lead or copper tap water samples. A sample invalidated under this subsection does not count toward determining lead or copper 90th percentile levels under Section 611.350(c)(3) or toward meeting the minimum monitoring requirements of subsection (c) of this Section. |
| 1) | The Agency must invalidate a lead or copper tap water sample if it determines that one of the following conditions exists: |
| A) | The laboratory establishes that improper sample analysis caused erroneous results; |
| B) | The sample was taken from a site that did not meet the site selection criteria of this Section; |
| C) | The sample container was damaged in transit; or |
| D) | There is substantial reason to believe that the sample was subject to tampering. |
| 2) | The supplier must report the results of all samples to the Agency and all supporting documentation for samples the supplier believes should be invalidated. |
| 3) | To invalidate a sample under subsection (f)(1) of this Section, the decision and the rationale for the decision must be documented in writing. The Agency may not invalidate a sample solely on the grounds that a follow-up sample result is higher or lower than that of the original sample. |
| 4) | The water supplier must collect replacement samples for any samples invalidated under this Section if, after the invalidation of one or more samples, the supplier has too few samples to meet the minimum requirements of subsection (c) of this Section. Any such replacement samples must be taken as soon as possible, but no later than 20 days after the date the Agency invalidates the sample or by the end of the applicable monitoring period, whichever occurs later. Replacement samples taken after the end of the applicable monitoring period must not also be used to meet the monitoring requirements of a subsequent monitoring period. The replacement samples must be taken at the same locations as the invalidated samples or, if that is not possible, at locations other than those already used for sampling during the monitoring period. |
| g) | Monitoring waivers for small system suppliers. Any small system supplier that meets the criteria of this subsection (g) may apply to the Agency to reduce the frequency of monitoring for lead and copper under this Section to once every nine years (i.e., a “full waiver”) if it meets all of the materials criteria specified in subsection (g)(1) of this Section and all of the monitoring criteria specified in subsection (g)(2) of this Section. Any small system supplier that meets the criteria in subsections (g)(1) and (g)(2) of this Section only for lead, or only for copper, may apply to the State for a waiver to reduce the frequency of tap water monitoring to once every nine years for that contaminant only (i.e., a “partial waiver”). |
| 1) | Materials criteria. The supplier must demonstrate that its distribution system and service lines and all drinking water supply plumbing, including plumbing conveying drinking water within all residences and buildings connected to the system, are free of lead-containing materials or copper-containing materials, as those terms are defined in this subsection (g)(1), as follows: |
| A) | Lead. To qualify for a full waiver, or a waiver of the tap water monitoring requirements for lead (i.e., a “lead waiver”), the water supplier must provide certification and supporting documentation to the Agency that the system is free of all lead-containing materials, as follows: |
| i) | It contains no plastic pipes which contain lead plasticizers, or plastic service lines which contain lead plasticizers; and |
| ii) | It is free of lead service lines, lead pipes, lead soldered pipe joints, and leaded brass or bronze alloy fittings and fixtures, unless such fittings and fixtures meet the specifications of NSF Standard 61, section 9, incorporated by reference in Section 611.102. |
BOARD NOTE: Corresponding 40 CFR 141.86(g)(1)(i)(B) specifies “any standard established pursuant to 42 U.S.C. 300g-6(e) (SDWA Section 1417(e)).” USEPA has stated that the NSF standard is that standard. See 62 Fed. Reg. 44684 (Aug. 22, 1997).
| B) | Copper. To qualify for a full waiver, or a waiver of the tap water monitoring requirements for copper (i.e., a “copper waiver”), the water supplier must provide certification and supporting documentation to the Agency that the system contains no copper pipes or copper service lines. |
| 2) | Monitoring criteria for waiver issuance. The supplier must have completed at least one six-month round of standard tap water monitoring for lead and copper at sites approved by the Agency and from the number of sites required by subsection (c) of this Section and demonstrate that the 90th percentile levels for any and all rounds of monitoring conducted since the system became free of all lead-containing and/or copper-containing materials, as appropriate, meet the following criteria: |
| A) | Lead levels. To qualify for a full waiver, or a lead waiver, the supplier must demonstrate that the 90th percentile lead level does not exceed 0.005 mg/L. |
| B) | Copper levels. To qualify for a full waiver, or a copper waiver, the supplier must demonstrate that the 90th percentile copper level does not exceed 0.65 mg/L. |
| 3) | State approval of waiver application. The Agency must notify the supplier of its waiver determination by a SEP issued pursuant to Section 611.110, in writing, setting forth the basis of its decision and any condition of the waiver. As a condition of the waiver, the Agency may require the supplier to perform specific activities (e.g., limited monitoring, periodic outreach to customers to remind them to avoid installation of materials that might void the waiver) to avoid the risk of lead or copper concentration of concern in tap water. The small system supplier must continue monitoring for lead and copper at the tap as required by subsections (d)(1) through (d)(4) of this Section, as appropriate, until it receives written notification from the Agency that the waiver has been approved. |
| 4) | Monitoring frequency for suppliers with waivers. |
| A) | A supplier with a full waiver must conduct tap water monitoring for lead and copper in accordance with subsection (d)(4)(D) of this Section at the reduced number of sampling sites identified in subsection (c) of this Section at least once every nine years and provide the materials certification specified in subsection (g)(1) of this Section for both lead and copper to the Agency along with the monitoring results. |
| B) | A supplier with a partial waiver must conduct tap water monitoring for the waived contaminant in accordance with subsection (d)(4)(D) of this Section at the reduced number of sampling sites specified in subsection (c) of this Section at least once every nine years and provide the materials certification specified in subsection (g)(1) of this Section pertaining to the waived contaminant along with the monitoring results. Such a supplier also must continue to monitor for the non-waived contaminant in accordance with requirements of subsection (d)(1) through (d)(4) of this Section, as appropriate. |
| C) | If a supplier with a full or partial waiver adds a new source of water or changes any water treatment, the supplier must notify the Agency in writing in accordance with Section 611.360(a)(3). The Agency has the authority to require the supplier to add or modify waiver conditions (e.g., require recertification that the supplier’s system is free of lead- containing or copper-containing materials, require additional rounds of monitoring), if it deems such modifications are necessary to address treatment or source water changes at the system. |
| D) | If a supplier with a full or partial waiver becomes aware that it is no longer free of lead-containing or copper-containing materials, as appropriate, (e.g., as a result of new construction or repairs), the supplier must notify the Agency in writing no later than 60 days after becoming aware of such a change. |
| 5) | Continued eligibility. If the supplier continues to satisfy the requirements of subsection (g)(4) of this Section, the waiver will be renewed automatically, unless any of the conditions listed in subsection (g)(5)(A) through (g)(5)(C) of this Section occurs. A supplier whose waiver has been revoked may re-apply for a waiver at such time as it again meets the appropriate materials and monitoring criteria of subsections (g)(1) and (g)(2) of this Section. |
| A) | A supplier with a full waiver or a lead waiver no longer satisfies the materials criteria of subsection (g)(1)(A) of this Section or has a 90th percentile lead level greater than 0.005 mg/L. |
| B) | A supplier with a full waiver or a copper waiver no longer satisfies the materials criteria of subsection (g)(1)(B) of this Section or has a 90th percentile copper level greater than 0.65 mg/L. |
| C) | The State notifies the supplier, in writing, that the waiver has been revoked, setting forth the basis of its decision. |
| 6) | Requirements following waiver revocation. A supplier whose full or partial waiver has been revoked by the Agency is subject to the corrosion control treatment and lead and copper tap water monitoring requirements, as follows: |
| A) | If the supplier exceeds the lead or copper action level, the supplier must implement corrosion control treatment in accordance with the deadlines specified in Section 611.351(e), and any other applicable requirements of this Subpart G of this Part. |
| B) | If the supplier meets both the lead and the copper action level, the supplier must monitor for lead and copper at the tap no less frequently than once every three years using the reduced number of sample sites specified in subsection (c) of this Section. |
| 7) | Pre-existing waivers. Small system supplier waivers approved by the Agency in writing prior to April 11, 2000 must remain in effect under the following conditions: |
BOARD NOTE: Corresponding 40 CFR 141.86(g)(7) sets forth the April 11, 2000 date. The Board has retained that date to maintain consistency with the federal requirements, despite the fact that this subsection (g)(7) became effective after that date.
| A) | If the supplier has demonstrated that it is both free of lead- containing and copper-containing materials, as required by subsection (g)(1) of this Section and that its 90th percentile lead levels and 90th percentile copper levels meet the criteria of subsection (g)(2) of this Section, the waiver remains in effect so long as the supplier continues to meet the waiver eligibility criteria of subsection (g)(5) of this Section. The first round of tap water monitoring conducted pursuant to subsection (g)(4) of this Section must be completed no later than nine years after the last time the supplier has monitored for lead and copper at the tap. |
| B) | If the supplier has met the materials criteria of subsection (g)(1) of this Section but has not met the monitoring criteria of subsection (g)(2) of this Section, the supplier must conduct a round of monitoring for lead and copper at the tap demonstrating that it meets the criteria of subsection (g)(2) of this Section no later than September 30, 2000. Thereafter, the waiver must remain in effect as long as the supplier meets the continued eligibility criteria of subsection (g)(5) of this Section. The first round of tap water monitoring conducted pursuant to subsection (g)(4) of this Section must be completed no later than nine years after the round of monitoring conducted pursuant to subsection (g)(2) of this Section. |
BOARD NOTE: Corresponding 40 CFR 141.86(g)(7)(ii) sets forth the September 30, 2000 date. The Board has retained that date to maintain consistency with the federal requirements, despite the fact that this subsection (g)(7)(B) became effective after that date.

| 1) | A supplier that fails to meet the lead action level or the copper action level on the basis of tap samples collected in accordance with Section 611.356 |
| A) | A groundwater supplier must take a minimum of one sample at every entry point to the distribution system that is representative of each well after treatment (hereafter called a sampling point). The supplier must take one sample at the same sampling point unless conditions make another sampling point more representative of each source or treatment plant. |
| B) | A surface water supplier must take a minimum of one sample at every entry point to the distribution system after any application of treatment or in the distribution system at a point that is representative of each source after treatment (hereafter called a sampling point). The system must take each sample at the same sampling point unless conditions make another sampling point more representative of each source or treatment plant. |
BOARD NOTE: For the purposes of this subsection (a)(1)(B), surface water systems include systems with a combination of surface and ground sources.
| C) | If a supplier draws water from more than one source and the sources are combined before distribution, the supplier must sample at an entry point to the distribution system during periods of normal operating conditions (i.e., when water is representative of all sources being used). |
| D) | The Agency may, by a SEP issued pursuant to Section 611.110, reduce the total number of samples which must be analyzed by allowing the use of compositing. Compositing of samples must be done by certified laboratory personnel. Composite samples from a maximum of five samples are allowed, provided that if the lead concentration in the composite sample is greater than or equal to 0.001 mg/L or the copper concentration is greater than or equal to 0.160 mg/ L, then the supplier must do either of the following: |
| i) | The supplier must take and analyze a follow-up sample within 14 days at each sampling point included in the composite; or |
| ii) | If duplicates of or sufficient quantities from the original samples from each sampling point used in the composite are available, the supplier may use these instead of resampling. |
| 2) | SEP requiring an additional sample |
| A) | When the Agency determines that the results of sampling indicate an exceedance of the lead or copper MPC established under Section 611.353(b)(4), it |
| B) | If a supplier takes an Agency-required confirmation sample for lead or copper, the supplier |
| i) | Any analytical result below the MDL |
| ii) | Any value above the MDL but below the PQL |
| b) | Monitoring frequency after system exceeds tap water action level. A supplier that exceeds the lead action level or the copper action level in tap sampling |
| c) | Monitoring frequency after installation of source water treatment. A supplier that installs source water treatment pursuant to Section 611.353(a)(3) |
| d) | Monitoring frequency after the Agency has specified the lead and copper MPCs or has determined that source water treatment is not needed. |
| 1) | A supplier |
| A) | GWS suppliers. |
| i) | A GWS supplier required to sample by subsection (d)(1) |
| ii) | A GWS supplier required to sample by subsection (d)(1) |
| B) | A SWS or mixed system supplier |
| 2) | A supplier is not required to conduct source water sampling for lead or copper if the supplier meets the action level for the specific contaminant in all tap water samples collected during the entire source water sampling period applicable under subsection (d)(1)(A) or (d)(1)(B) |
| e) | Reduced monitoring frequency. |
| 1) | A GWS supplier |
| A) | The supplier demonstrates that finished drinking water entering the distribution system has been maintained below the maximum permissible lead and copper concentrations specified by the State in Section 611.353(b)(4) during at least three consecutive compliance periods under subsection (d)(1) of this Section; or |
| B) | The Agency has determined, by a SEP issued pursuant to Section 611.110, that source water treatment is not needed and the system demonstrates that, during at least three consecutive compliance periods in which sampling was conducted under subsection (d)(1) of this Section, the concentration of lead in source water was less than or equal to 0.005 mg/L and the concentration of copper in source water was less than or equal to 0.65 mg/L. |
| 2) | A SWS or mixed system supplier |
| A) | The supplier demonstrates that finished drinking water entering the distribution system has been maintained below the maximum permissible lead and copper concentrations specified by the Agency under Section 611.353(b)(4) for at least three consecutive years; or |
| B) | The Agency has determined, by a SEP issued pursuant to Section 611.110, that source water treatment is not needed and the supplier demonstrates that, during at least three consecutive years, the concentration of lead in source water was less than or equal to 0.005 mg/L and the concentration of copper in source water was less than or equal to 0.65 mg/L. |
| 3) | A supplier that uses a new source of water is not eligible for reduced monitoring for lead or copper until it demonstrates by samples collected from the new source during three consecutive monitoring periods, of the appropriate duration provided by subsection (d)(1) |

| Section 611.360 | Reporting |
A supplier shall must report all of the following information to the Agency in accordance with this Section.
| a) | Reporting for tap, lead, and copper, and water quality parameter monitoring. |
| 1) | |
| A) | |
| B) | Documentation for each tap water lead or copper sample for which the water supplier requests invalidation pursuant to Section 611.356(f)(2); |
| C) | |
| C) | This subsection (a)(1)(C) corresponds with 40 CFR 141.89(a)(1)(iii), a provision that USEPA removed and marked “reserved” at 65 Fed. Reg. 2012 (Jan. 12, 2000). This statement preserves structural parity with the federal rules; |
| D) | |
| E) | |
| F) | |
| G) | |
| H) | A water supplier must report the results of all water quality parameter samples collected under Section 611.357(c) through (f) during each six-month monitoring period specified in Section 611.357(d) within the first 10 days following the end of the monitoring period, unless the Agency has specified, by a SEP granted pursuant to Section 611.110, a more frequent reporting requirement. |
| 2) | For a NTNCWS supplier, or a CWS supplier meeting the criteria of Sections 611.355(c)(7)(A) and (B), that does not have enough taps which can provide first-draw samples, the supplier must do either of the following: |
| A) | Provide written documentation to the Agency that identifies standing times and locations for enough non-first-draw samples to make up its sampling pool under Section 611.356(b)(5) by the start of the first applicable monitoring period under Section 611.356(d) that commences after April 11, 2000, unless the Agency has waived prior Agency approval of non-first-draw sample sites selected by the supplier pursuant to Section 611.356(b)(5); or |
BOARD NOTE: Corresponding 40 CFR 141.90(a)(2)(i) sets forth the April 11, 2000 date. The Board has retained that date to maintain structural consistency with the federal requirements, despite the fact that this subsection (a)(2)(A) became effective after that date.
| B) | If the Agency has waived prior approval of non-first-draw sample sites selected by the supplier, identify, in writing, each site that did not meet the six-hour minimum standing time and the length of standing time for that particular substitute sample collected pursuant to Section 611.356(b)(5) and include this information with the lead and copper tap sample results required to be submitted pursuant to subsection (a)(1)(A) of this Section. |
| 3) | No later than 60 days after the addition of a new source or any change in water treatment, unless the Agency requires earlier notification, a water supplier deemed to have optimized corrosion control under Section 611.351(b)(3), a water supplier subject to reduced monitoring pursuant to Section 611.356(d)(4), or a water supplier subject to a monitoring waiver pursuant to Section 611.356(g), must send written documentation to the Agency describing the change. In those instances where prior Agency approval of the treatment change or new source is not required, USEPA has stated that it encourages water systems to provide the notification to the Agency beforehand to minimize the risk the treatment change or new source will adversely affect optimal corrosion control. |
| 4) | Any small system supplier applying for a monitoring waiver under Section 611.356(g), or subject to a waiver granted pursuant to Section 611.356(g)(3), must provide the following information to the Agency in writing by the specified deadline: |
| A) | By the start of the first applicable monitoring period in Section 611.356(d), any small water system supplier applying for a monitoring waiver must provide the documentation required to demonstrate that it meets the waiver criteria of Sections 611.356(g)(1) and (g)(2). |
| B) | No later than nine years after the monitoring previously conducted pursuant to Section 611.356(g)(2) or Section 611.356(g)(4)(A), each small system supplier desiring to maintain its monitoring waiver must provide the information required by Sections 611.356(g)(4)(A) and (g)(4)(ii). |
| C) | No later than 60 days after it becomes aware that it is no longer free of lead-containing or copper-containing material, as appropriate, each small system supplier with a monitoring waiver must provide written notification to the Agency, setting forth the circumstances resulting in the lead-containing or copper-containing materials being introduced into the system and what corrective action, if any, the supplier plans to remove these materials. |
| D) | By October 10, 2000, any small system supplier with a waiver granted prior to April 11, 2000 and that has not previously met the requirements of Section 611.356(g)(2) must provide the information required by that subsection. |
BOARD NOTE: Corresponding 40 CFR 141.90(a)(2)(iv) sets forth the April 11, 2000 and October 10, 2000 dates. The Board has retained those dates to maintain structural consistency with the federal requirements, despite the fact that this subsection (a)(2)(D) became effective after that date.
| 5) | Each GWS supplier that limits water quality parameter monitoring to a subset of entry points under Section 611.357(c)(3) must provide, by the commencement of such monitoring, written correspondence to the Agency that identifies the selected entry points and includes information sufficient to demonstrate that the sites are representative of water quality and treatment conditions throughout the system. |
| b) | Reporting for source water monitoring. |
| 1) | A supplier |
| 2) | With the exception of the first round of source water sampling conducted pursuant to Section 611.358(b), a supplier |

| 3) | The annual letter submitted to the Agency pursuant to subsection (e)(2) |
| A) | |
| B) | |
| C) | |
BOARD NOTE: This communication is vital to a supplier seeking to replace less than entire service lines. Under Section 611.354(e)(1), a supplier is presumed to control the entire service line unless it makes an affirmative showing. Under Section 611.354(d)(2)(A), a supplier is affirmatively required to replace all of each service line except as to any particular service line for which the Agency has made an affirmative determination that the supplier does not control in its entirety. Under Sections 611.354(b)(1) and (b)(4), the supplier must have completed replacing seven percent of the lead service lines within a year of the day of the event that triggered the requirement. Section 39(a) of the Act allows the Agency 90 days to render its decision on any permit request. Therefore, any supplier that desires an Agency determination pursuant to Section 611.354(e)(2) must submit the required information within the three month time-frame of this subsection.
| 4) | Any supplier that collects lead service line samples following partial lead service line replacement required by Section 611.354 must report the results to the Agency within the first ten days of the month following the month in which the supplier receives the laboratory results, or as specified by the Agency. The Agency may, by a SEP granted pursuant to Section 611.110, eliminate this requirement to report these monitoring results. A supplier must also report any additional information as specified by the Agency, and in a time and manner prescribed by the Agency, to verify that all partial lead service line replacement activities have taken place. |
| f) | Reporting for public education program. |
| 1) | Any water supplier that is subject to the public education requirements in Section 611.355 must, within ten days after the end of each period in which the supplier is required to perform public education tasks in accordance with Section 611.355(c), send written documentation to the Agency that contains: |
| A) | A demonstration that the supplier has delivered the public education materials that meet the content requirements in Section 611.355(a) and (b) and the delivery requirements in Section 611.355(c); and |
| B) | A list of all the newspapers, radio stations, television stations, and facilities and organizations to which the supplier delivered public education materials during the period in which the supplier was required to perform public education tasks. |
| 2) | Unless required by the Agency, by a SEP issued pursuant to Section 611.110, a supplier that previously has submitted the information required by subsection (f)(1)(B) of this Section need not resubmit the information required by subsection (f)(1)(B) of this Section, as long as there have been no changes in the distribution list and the supplier certifies that the public education materials were distributed to the same list submitted previously. |
| g) | Reporting of additional monitoring data. Any supplier that collects sampling data in addition to that required by this Subpart |
| h) | Reporting of 90th percentile lead and copper concentrations where the Agency calculates a system’s 90th percentile concentrations. A water supplier is not required to report the 90th percentile lead and copper concentrations measured from among all lead and copper tap water samples collected during each monitoring period, as required by subsection (a)(1)(D) of this Section if: |
| 1) | The Agency has previously notified the water supplier that it will calculate the water system’s 90th percentile lead and copper concentrations, based on the lead and copper tap results submitted pursuant to subsection (h)(2)(A) of this Section, and has specified a date before the end of the applicable monitoring period by which the supplier must provide the results of lead and copper tap water samples; |
| 2) | The supplier has provided the following information to the Agency by the date specified in subsection (h)(1) of this Section: |
| A) | The results of all tap samples for lead and copper including the location of each site and the criteria under Section 611.356(a)(3), (a)(4), (a)(5), (a)(6), or (a)(7) under which the site was selected for the system’s sampling pool, pursuant to subsection (a)(1)(A) of this Section; and |
| B) | An identification of sampling sites utilized during the current monitoring period that were not sampled during previous monitoring periods, and an explanation why sampling sites have changed; and |
| 3) | The Agency has provided the results of the 90th percentile lead and copper calculations, in writing, to the water supplier before the end of the monitoring period. |

BOARD NOTE: Derived from 40 CFR 141.151 (1999).
(Source: Amended at 25 Ill. Reg. ________ effective ______________________)
| Section 611.883 | Content of the Reports |
| a) | Each CWS |
| b) | Information on the source of the water delivered |
| 1) | Each report must identify the |
| A) | The type of the water |
| B) | The commonly used name (if any) and location of the body (or bodies) of water. |
| 2) | If a source water assessment has been completed, the report must notify consumers of the availability of this information and the means to obtain it. In addition, systems are encouraged to highlight in the report significant sources of contamination in the source water area if they have readily available information. Where a system has received a source water assessment from the Agency, the report must include a brief summary of the system’s susceptibility to potential sources of contamination, using language provided by the Agency or written by the PWS. |
| c) | Definitions. |
| 1) | Each report must include the following definitions: |
| A) | Maximum Contaminant Level Goal or MCLG: The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. |
BOARD NOTE: Although an MCLG is not an NPDWR that the Board must include in the Illinois SDWA regulations, the use of this definition is mandatory where the term “MCLG” is defined.
| B) | Maximum Contaminant Level or MCL: The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology. |
| 2) | A report for a CWS operating under relief from an NPDWR issued under Sections 611.111, 611.112, 611.130, or 611.131 must include the following definition: “Variances, Adjusted Standards, and Site-specific Rules: State permission not to meet an MCL or a treatment technique under certain conditions.” |
| 3) | A report that contains data on |
| A) | Treatment Technique: A required process intended to reduce the level of a contaminant in drinking water. |
| B) | Action Level: The concentration of a contaminant that, if exceeded, triggers treatment or other requirements which a water system must follow. |
C) Maximum residual disinfectant level goal or MRDLG: The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.
BOARD NOTE: Although an MRDLG is not an NPDWR that the Board must include in the Illinois SDWA regulations, the use of this definition is mandatory where the term “MRDLG” is defined.
D) Maximum residual disinfectant level or MRDL: The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
| d) | Information on detected contaminants. |
| 1) | This subsection (d) specifies the requirements for information to be included in each report for contaminants subject to mandatory monitoring (except Cryptosporidium). It applies to the following: |
| A) | Contaminants subject to an MCL, action level, MRDL, or treatment technique (regulated contaminants); |
| B) | Contaminants for which monitoring is required by Section 611.510 (unregulated contaminants); and |
| C) | Disinfection byproducts or microbial contaminants for which monitoring is required by Section 611.382 and Subpart L, except as provided under subsection (e)(1) of this Section, and which are detected in the finished water. |
| 2) | The data relating to these contaminants must be displayed in one table or in several adjacent tables. Any additional monitoring results that a CWS chooses to include in its report must be displayed separately. |
| 3) | The data must be derived from data collected to comply with monitoring and analytical requirements during calendar year 1998 for the first report and subsequent calendar years thereafter, except that the following requirements also apply: |
| A) | Where a system is allowed to monitor for regulated contaminants less often than once a year, the |
| B) | Results of monitoring in compliance with Section 611.382 and Subpart L need only be included for five years from the date of last sample or until any of the detected contaminants becomes regulated and subject to routine monitoring requirements, whichever comes first. |
| 4) | For detected regulated contaminants (listed in Appendix |
| A) | The MCL for that contaminant expressed as a number equal to or greater than 1.0 (as provided Appendix |
| B) | The Maximum Contaminant Level Goal (MCLG) for that contaminant expressed in the same units as the MCL |
| C) | If there is no MCL for a detected contaminant, the table must indicate that there is a treatment technique, or specify the action level, applicable to that contaminant, and the report must include the definitions for treatment technique or action level, as appropriate, specified in subsection (c)(3) of this Section; |
| D) | For contaminants subject to an MCL, except turbidity and total coliforms, the highest contaminant level used to determine compliance with an NPDWR, and the range of detected levels, as follows: |
| i) | When compliance with the MCL is determined annually or less frequently: |
| ii) | When compliance with the MCL is determined by calculating a running annual average of all samples taken at a sampling point: the highest average of any of the sampling points and the range of all sampling points expressed in the same units as the MCL. |
| iii) | When compliance with the MCL is determined on a system-wide basis by calculating a running annual average of all samples at all sampling points: the average and range of detection expressed in the same units as the MCL; |
BOARD NOTE to subsection (d)(4)(D): When rounding of results to determine compliance with the MCL is allowed by the regulations, rounding should be done prior to multiplying the results by the factor listed in Appendix FA; derived from 40 CFR 153 (1998) (1999).
| E) | For turbidity the following: |
| i) | When it is reported pursuant to Section 611.560: |
| ii) | When it is reported pursuant to the requirements of Section 611.211(b): The highest monthly value. |
| iii) | When it is reported pursuant to Section 611.250 or 611.743: |
| F) | For lead and copper the following: the 90th percentile value of the most recent round of sampling and the number of sampling sites exceeding the action level; |
| G) | For total coliform the following: |
| i) | The highest monthly number of positive samples for systems collecting fewer than 40 samples per month; or |
| ii) | The highest monthly percentage of positive samples for systems collecting at least 40 samples per month; |
| H) | For fecal coliform the following: the total number of positive samples; and |
| I) | The likely |
| 5) | If a CWS distributes water to its customers from multiple hydraulically independent distribution systems that are fed by different raw water sources, the table must contain a separate column for each service area and the report must identify each separate distribution system. Alternatively, a CWS may produce separate reports tailored to include data for each service area. |
| 6) | The |
| 7) | For detected unregulated contaminants for which monitoring is required (except Cryptosporidium), the |
| e) | Information on Cryptosporidium, radon, and other contaminants: |
| 1) | If the CWS has performed any monitoring for Cryptosporidium, including monitoring performed to satisfy the requirements of Subpart L of this Part, that indicates that Cryptosporidium may be present in the source water or the finished water, the report must include the following: |
| A) | A summary of the results of the monitoring; and |
B) An explanation of the significance of the results.
| 2) | If the CWS has performed any monitoring for radon which indicates that radon may be present in the finished water, the report must include the following: |
| A) | The results of the monitoring; and |
| B) | An explanation of the significance of the results. |
| 3) | If the CWS has performed additional monitoring that indicates the presence of other contaminants in the finished water, the report must include the following: |
| A) | The results of the monitoring; and |
| B) | An explanation of the significance of the results noting the existence of any health advisory or proposed regulation. |
| f) | Compliance with an NPDWR. In addition to the requirements of subsection (d)(6) of this Section, the report must note any violation that occurred during the year covered by the report of a requirement listed below, and include a clear and readily understandable explanation of the violation, any potential adverse health effects, and the steps the CWS has taken to correct the violation. |
| 1) | Monitoring and reporting of compliance data; |
| 2) | Filtration and disinfection prescribed by Subpart B of this Part. For CWSs that have failed to install adequate filtration or disinfection equipment or processes, or have had a failure of such equipment or processes which constitutes a violation, the report must include the following language as part of the explanation of potential adverse health effects: Inadequately treated water may contain disease-causing organisms. These organisms include bacteria, viruses, and parasites that can cause symptoms such as nausea, cramps, diarrhea, and associated headaches. |
| 3) | Lead and copper control requirements prescribed by Subpart G of this Part. For systems that fail to take one or more actions prescribed by Sections 611.350(d), 611.351, 611.352, 611.353, or 611.354, the report must include the applicable language of Appendix |
| 4) | Treatment techniques for acrylamide and epichlorohydrin prescribed by Section 611.296. For systems that violate the requirements of Section 611.296, the report must include the relevant language from |
| 5) | Recordkeeping of compliance data. |
| 6) | Special monitoring requirements prescribed by Sections 611.510 and 611.630; and |
| 7) | Violation of the terms of a variance, adjusted standard, site-specific rule, or administrative or judicial order. |
| g) | Variances, adjusted standards, and site-specific rules. If a system is operating under the terms of a variance, adjusted standard, or site-specific rule issued under Sections 611.111, 611.112, or 611.131, the report must contain the following: |
| 1) | An explanation of the reasons for the variance, adjusted standard, or site-specific rule; |
| 2) | The date on which the variance, adjusted standard, or site-specific rule was issued; |

| 4) | A notice of any opportunity for public input in the review, or renewal, of the variance, adjusted standard, or site-specific rule. |
| h) | Additional information |
| 1) | The report must contain a brief explanation regarding contaminants that may reasonably be expected to be found in drinking water, including bottled water. This explanation may include the language of subsections (h)(1)(A) through (h)(1)(C) of this Section or CWSs may use their own comparable language. The report also must include the language of subsection (h)(1)(D) of this Section. |
| A) | The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radioactive material, and can pick up substances resulting from the presence of animals or from human activity. |
| B) | Contaminants that may be present in source water include the following: |
| i) | Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife; |
| ii) | Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming; |
| iii) | Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses; |
| iv) | Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems; and |
| v) | Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities. |
| C) | In order to ensure that tap water is safe to drink, USEPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. United States Food and Drug Administration (USFDA) regulations establish limits for contaminants in bottled water that must provide the same protection for public health. |
| D) | Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the USEPA Safe Drinking Water Hotline (800-426-4791). |
| 2) | The report must include the telephone number of the owner, operator, or designee of the CWS as a source of additional information concerning the report. |
| 3) | In communities with a large proportion of non-English speaking residents, as determined by the Agency, the report must contain information in the appropriate |
| 4) | The report must include information about opportunities for public participation in decisions that may affect the quality of the water. |
| 5) | The CWS may include such additional information as it deems necessary for public education consistent with, and not detracting from, the purpose of the report. |

Each owner or operator of a public water system (a CWS, a NTNCWSs, or a transient non-CWS) must give notice for all violations of a NPDWR and for other situations, as listed in this subsection (a). The term “NPDWR violation” is used in this Subpart V to include violations of an MCL, an MRDL, a treatment technique, monitoring requirements, or a testing procedure set forth in this Part. Appendix G to this Part identifies the tier assignment for each specific violation or situation requiring a public notice.
1) NPDWR violations:
A) A failure to comply with an applicable MCL or MRDL.
B) A failure to comply with a prescribed treatment technique.
C) A failure to perform water quality monitoring, as required by this Part.
D) A failure to comply with testing procedures as prescribed by this Part.
2) Relief equivalent to a variance and exemptions under sections 1415 and 1416 of SDWA:
A) Operation under relief equivalent to a SDWA Section 1415 variance, under Section 611.111, or a SDWA Section 1416 exemption, under Section 611.112.
B) A failure to comply with the requirements of any schedule that has been set under relief equivalent to a SDWA Section 1415 variance, under Section 611.111, or a SDWA Section 1415 exemption, under Section 611.112.
3) Special public notices:
A) The occurrence of a waterborne disease outbreak or other waterborne emergency.
B) An exceedance of the nitrate MCL by a non-CWS, where granted permission by the Agency under Section 611.300(d).
C) An exceedance of the secondary fluoride standard of Section 611.858.
D) The availability of unregulated contaminant monitoring data.
E) Other violations and situations determined by the Agency by a SEP issued pursuant to Section 611.110 to require a public notice under this Subpart, not already listed in Appendix G.
b) The type of public notice required for each violation or situation. The public notice requirements of this Subpart V are divided into three tiers, to take into account the seriousness of the violation or situation and of any potential adverse health effects that may be involved. The public notice requirements for each violation or situation listed in subsection section (a) of this Section are determined by the tier to which it is assigned. This subsection (b) provides the definition of each tier. Appendix G of this Part identifies the tier assignment for each specific violation or situation.
1) Tier 1 public notice: required for NPDWR violations and situations with significant potential to have serious adverse effects on human health as a result of short-term exposure.
2) Tier 2 public notice: required for all other NPDWR violations and situations with potential to have serious adverse effects on human health.
3) Tier 3 public notice: required for all other NPDWR violations and situations not included in Tier 1 and Tier 2.
c) Who must receive notice.
1) Each PWS supplier must provide public notice to persons served by the water supplier, in accordance with this Subpart V. A PWS supplier that sells or otherwise provides drinking water to another PWS supplier (i.e., to a consecutive system) is required to give public notice to the owner or operator of the consecutive system; the consecutive system supplier is responsible for providing public notice to the persons it serves.
2) If a PWS supplier has a violation in a portion of the distribution system that is physically or hydraulically isolated from other parts of the distribution system, the Agency may allow the system to limit distribution of the public notice to only persons served by that portion of the system which is out of compliance. Permission by the Agency for limiting distribution of the notice must be granted in writing, by a SEP granted pursuant to Section 611.110.
3) A copy of the notice must also be sent to the Agency, in accordance with the requirements under Section 611.840(d).

7) Occurrence of a waterborne disease outbreak, as defined in Section 611.101, or other waterborne emergency (such as a failure or significant interruption in key water treatment processes, a natural disaster that disrupts the water supply or distribution system, or a chemical spill or unexpected loading of possible pathogens into the source water that significantly increases the potential for drinking water contamination);
8) Other violations or situations with significant potential to have serious adverse effects on human health as a result of short-term exposure, as determined by the Agency by a SEP issued pursuant to Section 611.110.
b) When the Tier 1 public notice is to be provided. Additional steps required. A PWS supplier must:
1) Provide a public notice as soon as practical but no later than 24 hours after the supplier learns of the violation;
2) Initiate consultation with the Agency as soon as practical, but no later than 24 hours after the PWS supplier learns of the violation or situation, to determine additional public notice requirements; and
3) Comply with any additional public notification requirements (including any repeat notices or direction on the duration of the posted notices) that are established as a result of the consultation with the Agency. Such requirements may include the timing, form, manner, frequency, and content of repeat notices (if any) and other actions designed to reach all persons served.
c) The form and manner of the public notice. A PWS supllier must provide the notice within 24 hours in a form and manner reasonably calculated to reach all persons served. The form and manner used by the PWS supplier are to fit the specific situation, but must be designed to reach residential, transient, and non-transient users of the water system. In order to reach all persons served, a water supplier is to use, at a minimum, one or more of the following forms of delivery:
1) Appropriate broadcast media (such as radio and television);
2) Posting of the notice in conspicuous locations throughout the area served by the water supplier;
3) Hand delivery of the notice to persons served by the water supplier; or
4) Another delivery method approved in writing by the Agency by a SEP issued pursuant to Section 611.110.

Section 611.903 Tier 2 Public Notice--Form, Manner, and Frequency of Notice
a) Which violations or situations require a Tier 2 public notice. This subsection lists the violation categories and other situations requiring a Tier 2 public notice. Appendix G to this Part identifies the tier assignment for each specific violation or situation.
1) All violations of the MCL, MRDL, and treatment technique requirements, except where a Tier 1 notice is required under Section 611.902(a) or where the Agency determines by a SEP issued pursuant to Section 611.110 that a Tier 1 notice is required;
2) Violations of the monitoring and testing procedure requirements, where the Agency determines by a SEP issued pursuant to Section 611.110 that a Tier 2 rather than a Tier 3 public notice is required, taking into account potential health impacts and persistence of the violation; and
3) Failure to comply with the terms and conditions of any relief equivalent to a SDWA Section 1415 variance or a SDWA Section 1416 exemption in place.
b) When Tier 2 public notice is to be provided.
1) A PWS supplier must provide the public notice as soon as practical, but no later than 30 days after the supplier learns of the violation. If the public notice is posted, the notice must remain in place for as long as the violation or situation persists, but in no case for less than seven days, even if the violation or situation is resolved. The Agency may, in appropriate circumstances, by a SEP issue pursuant to Section 611.110, allow additional time for the initial notice of up to three months from the date the supplier learns of the violation. It is not appropriate for the Agency to grant an extension to the 30-day deadline for any unresolved violation or to allow across-the-board extensions by rule or policy for other violations or situations requiring a Tier 2 public notice. Extensions granted by the Agency must be in writing.
2) The PWS supplier must repeat the notice every three months as long as the violation or situation persists, unless the Agency determines that appropriate circumstances warrant a different repeat notice frequency. In no circumstance may the repeat notice be given less frequently than once per year. It is not appropriate for the Agency to allow less frequent repeat notice for an MCL violation under the Total Coliform Rule or a treatment technique violation under the Surface Water Treatment Rule or Interim Enhanced Surface Water Treatment Rule. It is also not appropriate for the Agency to allow across-the-board reductions in the repeat notice frequency for other ongoing violations requiring a Tier 2 repeat notice. An Agency determination allowing repeat notices to be given less frequently than once every three months must be in writing.
3) For the turbidity violations specified in this subsection (b)(3), a PWS supplier must consult with the Agency as soon as practical but no later than 24 hours after the supplier learns of the violation, to determine whether a Tier 1 public notice under Section 611.902(a) is required to protect public health. When consultation does not take place within the 24-hour period, the water system must distribute a Tier 1 notice of the violation within the next 24 hours (i.e., no later than 48 hours after the supplier learns of the violation), following the requirements under Section 611.902(b) and (c). Consultation with the Agency is required for the following:
A) Violation of the turbidity MCL under Section 141.320(b); or
B) Violation of the SWTR or IESWTR treatment technique requirement resulting from a single exceedance of the maximum allowable turbidity limit.
c) The form and manner of Tier 2 public notice. A PWS supplier must provide the initial public notice and any repeat notices in a form and manner that is reasonably calculated to reach persons served in the required time period. The form and manner of the public notice may vary based on the specific situation and type of water system, but it must at a minimum meet the following requirements:
1) Unless directed otherwise by the Agency in writing, by a SEP issued pursuant to Section 611.110, a CWS supplier must provide notice by:
A) Mail or other direct delivery to each customer receiving a bill and to other service connections to which water is delivered by the PWS supplier; and
B) Any other method reasonably calculated to reach other persons regularly served by the supplier, if they would not normally be reached by the notice required in subsection (c)(1)(A) of this Section. Such persons may include those who do not pay water bills or do not have service connection addresses (e.g., house renters, apartment dwellers, university students, nursing home patients, prison inmates, etc.). Other methods may include: Publication in a local newspaper; delivery of multiple copies for distribution by customers that provide their drinking water to others (e.g., apartment building owners or large private employers); posting in public places served by the supplier or on the Internet; or delivery to community organizations.
2) Unless directed otherwise by the Agency in writing, by a SEP issued pursuant to Section 611.110, a non-CWS supplier must provide notice by the following:
A) Posting the notice in conspicuous locations throughout the distribution system frequented by persons served by the supplier, or by mail or direct delivery to each customer and service connection (where known); and
B) Any other method reasonably calculated to reach other persons served by the system if they would not normally be reached by the notice required in subsection (c)(2)(A) of this Section. Such persons may include those served who may not see a posted notice because the posted notice is not in a location they routinely pass by. Other methods may include the following: Publication in a local newspaper or newsletter distributed to customers; use of E-mail to notify employees or students; or, delivery of multiple copies in central locations (e.g., community centers).

1) A PWS supplier must provide the public notice not later than one year after the supplier learns of the violation or situation or begins operating under relief equivalent to a SDWA Section 1415 variance or Section 1416 exemption. Following the initial notice, the supplier must repeat the notice annually for as long as the violation, relief equivalent to a SDWA Section 1415 variance or Section 1416 exemption, or other situation persists. If the public notice is posted, the notice must remain in place for as long as the violation, relief equivalent to a SDWA Section 1415 variance or Section 1416 exemption, or other situation persists, but in no case less than seven days (even if the violation or situation is resolved).
2) Instead of individual Tier 3 public notices, a PWS supplier may use an annual report detailing all violations and situations that occurred during the previous twelve months, as long as the timing requirements of subsection (b)(1) of this Section are met.
c) The form and manner of the Tier 3 public notice. A PWS supplier must provide the initial notice and any repeat notices in a form and manner that is reasonably calculated to reach persons served in the required time period. The form and manner of the public notice may vary based on the specific situation and type of water system, but it must at a minimum meet the following requirements:

Section 611.908 Special Notice for Exceedance of the Fluoride Secondary Standard
a) When to give special notice. A CWS supplier that exceeds the fluoride secondary standard of 2 mg/l, as specified in Section 611.858 (determined by the last single sample taken in accordance with Section 611.603), but do not exceed the maximum contaminant level (MCL) of 4 mg/l for fluoride (as specified in Section 611.301), must provide the public notice in subsection (c) of this Section to persons served. Public notice must be provided as soon as practical but no later than 12 months from the day the supplier learns of the exceedance. A copy of the notice must also be sent to all new billing units and new customers at the time service begins and to the Department of Pubic Health. The PWS supplier must repeat the notice at least annually for as long as the SMCL is exceeded. If the public notice is posted, the notice must remain in place for as long as the fluoride secondary standard is exceeded, but in no case less than seven days (even if the exceedance is eliminated). On a case-by-case basis, the Agency may require an initial notice sooner than 12 months and repeat notices more frequently than annually.
b) The form and manner of a special notice. The form and manner of the public notice (including repeat notices) must follow the requirements for a Tier 3 public notice in Section 611.904(c), (d)(1), and (d)(3).
c) Mandatory language in a special notice. The notice must contain the following language, including the language necessary to fill in the blanks:
This is an alert about your drinking water and a cosmetic dental problem that might affect children under nine years of age. At low levels, fluoride can help prevent cavities, but children drinking water containing more than 2 milligrams per liter (mg/L) of fluoride may develop cosmetic discoloration of their permanent teeth (dental fluorosis). The drinking water provided by your community water system [name] has a fluoride concentration of [insert value] mg/L. Dental fluorosis, in its moderate or severe forms, may result in a brown staining and/or pitting of the permanent teeth. This problem occurs only in developing teeth, before they erupt from the gums. Children under nine should be provided with alternative sources of drinking water or water that has been treated to remove the fluoride to avoid the possibility of staining and pitting of their permanent teeth. You may also want to contact your dentist about proper use by young children of fluoride-containing products. Older children and adults may safely drink the water.
Drinking water containing more than 4 mg/L of fluoride (the USEPA’s drinking water standard) can increase your risk of developing bone disease. Your drinking water does not contain more than 4 mg/l of fluoride, but we’re required to notify you when we discover that the fluoride levels in your drinking water exceed 2 mg/l because of this cosmetic dental problem.
For more information, please call [name of water system contact] of [name of community water system] at [phone number]. Some home water treatment units are also available to remove fluoride from drinking water. To learn more about available home water treatment units, you may call NSF International at 1-877-8-NSF-HELP.”

Treatment Technique |
The United States Environmental Protection Agency (USEPA) sets drinking water standards and has determined that heptachlor is a health concern at certain levels of exposure. This organic chemical was once a popular pesticide. When soil and climatic conditions are favorable, heptachlor may get into drinking water by runoff into surface water or by leaching into groundwater. This chemical has been shown to cause cancer in laboratory animals such as rats and mice when the animals are exposed at high levels over their lifetimes. Chemicals that cause cancer in laboratory animals also may increase the risk of cancer in humans who are exposed over long periods of time. USEPA has set the drinking water standards for heptachlor at 0.0004 parts per million (ppm) to reduce the risk of cancer or other adverse health effects which have been observed in laboratory animals. Drinking water that meets this standard is associated with little to none of this risk and is considered safe with respect to heptachlor.
Note: In addition to the language in this introductory text of subsection (78), systems must include either the language in subsection (78)(a) or (78)(b) of this Appendix. Systems with a violation at the treatment plant, but not in the distribution system, are required to use the language in subsection (78)(a) and treat the violation as a nonacute violation. Systems with a violation in the distribution system are required to use the language in subsection (78)(b) of this Appendix and treat the violation as an acute violation.

| Mandatory Lead Public Education Information for Community Water Systems | |
| 1) | INTRODUCTION |
The United States Environmental Protection Agency (USEPA) and [insert name of water supplier] are concerned about lead in your drinking water. Although most homes have very low levels of lead in their drinking water, some homes in the community have lead levels above the USEPA action level of 15 parts per billion (ppb), or 0.015 milligrams of lead per liter of water (mg/L). Under Federal law we are required to have a program in place to minimize lead in your drinking water by [insert date when corrosion control will be completed for your system]. This program includes corrosion control treatment, source water treatment, and public education. We are also required to replace the portion of each lead service line that we control own if the line contributes lead concentrations of more than 15 ppb after we have completed the comprehensive treatment program. If you have any questions about how we are carrying out the requirements of the lead regulation please give us a call at [insert water system's phone number]. This brochure explains the simple steps you can take to protect you and your family by reducing your exposure to lead in drinking water.
| 2) | HEALTH EFFECTS OF LEAD |
Lead is a common metal found throughout the environment in lead-based paint, air, soil, household dust, food, certain types of pottery porcelain and pewter, and water. Lead can pose a significant risk to your health if too much of it enters your body. Lead builds up in the body over many years and can cause damage to the brain, red blood cells, and kidneys. The greatest risk is to young children and pregnant women. Amounts of lead that won't hurt adults can slow down normal mental and physical development of growing bodies. In addition, a child at play often comes into contact with sources of lead contamination -- like dirt and dust -- that rarely affect an adult. It is important to wash children's hands and toys often, and to try to make sure they only put food in their mouths.
| 3) | LEAD IN DRINKING WATER |
| A) | Lead in drinking water, although rarely the sole cause of lead poisoning, can significantly increase a person's total lead exposure, particularly the exposure of infants who drink baby formulas and concentrated juices that are mixed with water. The EPA estimates that drinking water can make up 20 percent or more of a person's total exposure to lead. |
| B) | Lead is unusual among drinking water contaminants in that it seldom occurs naturally in water supplies like rivers and lakes. Lead enters drinking water primarily as a result of the corrosion, or wearing away, of materials containing lead in the water distribution system and household plumbing. These materials include lead-based solder used to join copper pipe, brass and chrome plated brass faucets, and in some cases, pipes made of lead that connect your house to the water main (service lines). In 1986, Congress banned the use of lead solder containing greater than 0.2% lead, and restricted the lead content of faucets, pipes and other plumbing materials to 8.0%. |
| C) | When water stands in lead pipes or plumbing systems containing lead for several hours or more, the lead may dissolve into your drinking water. This means the first water drawn from the tap in the morning, or later in the afternoon after returning from work or school, can contain fairly high levels of lead. |
| 4) | STEPS YOU CAN TAKE IN THE HOME TO REDUCE EXPOSURE TO LEAD IN DRINKING WATER |
| A) | Despite our best efforts mentioned earlier to control water corrosivity and remove lead from the water supply, lead levels in some homes or buildings can be high. To find out whether you need to take action in your own home, have your drinking water tested to determine if it contains excessive concentrations of lead. Testing the water is essential because you cannot see, taste, or smell lead in drinking water. Some local laboratories that can provide this service are listed at the end of this booklet. For more information on having your water tested, please call [insert phone number of water system]. |
| B) | If a water test indicates that the drinking water drawn from a tap in your home contains lead above 15 ppb, then you should take the following precautions: |
| i) | Let the water run from the tap before using it for drinking or cooking any time the water in a faucet has gone unused for more than six hours. The longer water resides in your home's plumbing the more lead it may contain. Flushing the tap means running the cold water faucet until the water gets noticeably colder, usually about 15-30 seconds. If your house has a lead service line to the water main, you may have to flush the water for a longer time, perhaps one minute, before drinking. Although toilet flushing or showering flushes water through a portion of your home's plumbing system, you still need to flush the water in each faucet before using it for drinking or cooking. Flushing tap water is a simple and inexpensive measure you can take to protect your family's health. It usually uses less than one or two gallons of water and costs less than [insert a cost estimate based on flushing two times a day for 30 days] per month. To conserve water, fill a couple of bottles for drinking water after flushing the tap, and whenever possible use the first flush water to wash the dishes or water the plants. If you live in a high-rise building, letting the water flow before using it may not work to lessen your risk from lead. The plumbing systems have more, and sometimes larger pipes than smaller buildings. Ask your landlord for help in locating the source of the lead and for advice on reducing the lead level. |
| ii) | Try not to cook with, or drink water from the hot water tap. Hot water can dissolve more lead more quickly than cold water. If you need hot water, draw water from the cold tap and heat it on the stove. |
| iii) | Remove loose lead solder and debris from the plumbing materials installed in newly constructed homes, or homes in which the plumbing has recently been replaced, by removing the faucet strainers from all taps and running the water from 3 to 5 minutes. Thereafter, periodically remove the strainers and flush out any debris that has accumulated over time. |
| iv) | If your copper pipes are joined with lead solder that has been installed illegally since it was banned in 1986, notify the plumber who did the work and request that he or she replace the lead solder with lead-free solder. Lead solder looks dull gray, and when scratched with a key looks shiny. In addition, notify your State [insert name of department responsible for enforcing the Safe Drinking Water Act in your State] about the violation. |
| v) | Determine whether or not the service line that connects your home or apartment to the water main is made of lead. The best way to determine if your service line is made of lead is by either hiring a licensed plumber to inspect the line or by contacting the plumbing contractor who installed the line. You can identify the plumbing contractor by checking the city's record of building permits which should be maintained in the files of the [insert name of department that issues building permits]. A licensed plumber can at the same time check to see if your homes's plumbing contains lead solder, lead pipes, or pipe fittings that contain lead. The public water system that delivers water to your home should also maintain records of the materials located in the distribution system. If the service line that connects your dwelling to the water main contributes more than 15 ppb to drinking water, after our comprehensive treatment program is in place, we are required to replace the portion of the line that we own. If the line is only partially |
| vi) | Have an electrician check your wiring. If grounding wires from the electrical system are attached to your pipes, corrosion may be greater. Check with a licensed electrician or your local electrical code to determine if your wiring can be grounded elsewhere. DO NOT attempt to change the wiring yourself because improper grounding can cause electrical shock and fire hazards. |
| C) | The steps described above will reduce the lead concentrations in your drinking water. However, if a water test indicates that the drinking water coming from your tap contains lead concentrations in excess of 15 ppb after flushing, or after we have completed our actions to minimize lead levels, then you may want to take the following additional measures: |
| i) | Purchase or lease a home treatment device. Home treatment devices are limited in that each unit treats only the water that flows from the faucet to which it is connected, and all of the devices require periodic maintenance and replacement. Devices such as reverse osmosis systems or distillers can effectively remove lead from your drinking water. Some activated carbon filters may reduce lead levels at the tap, however all lead reduction claims should be investigated. Be sure to check the actual performance of a specific home treatment device before and after installing the unit. |
| ii) | Purchase bottled water for drinking and cooking. |
| D) | You can consult a variety of sources for additional information. Your family doctor or pediatrician can perform a blood test for lead and provide you with information about the health effects of lead. State and local government agencies that can be contacted include the following: |
| i) | [insert the name of city or county department of public utilities] at [insert phone number] can provide you with information about your community's water supply, and a list of local laboratories that have been certified by EPA for testing water quality; |
| ii) | [insert the name of city or county department that issues building permits] at [insert phone number] can provide you with information about building permit records that should contain the names of plumbing contractors that plumbed your home; and |
| iii) | [insert the name of the State Department of Public Health] at [insert phone number] or the [insert the name of the city or county health department] at [insert phone number] can provide you with information about the health effects of lead and how you can have your child's blood tested. |
| E) | The following is a list of some State-approved laboratories in your area that you can call to have your water tested for lead. [Insert names and phone numbers of at least two laboratories]. |

Appendix G--Endnotes
1. Violations and other situations not listed in this table (e.g., reporting violations and failure to prepare Consumer Confidence Reports), do not require notice, unless otherwise determined by the Agency by a SEP issued pursuant to Section 611.110. The Agency may, by a SEP issued pursuant to Section 611.110, further require a more stringent public notice tier (e.g., Tier 1 instead of Tier 2 or Tier 2 instead of Tier 3) for specific violations and situations listed in this Appendix, as authorized under Sections 611.902(a) and 611.903(a).
2. Definition of the abbreviations used: “MCL” means maximum contaminant level, “MRDL” means maximum residual disinfectant level, and “TT” means treatment technique
3. The term “violations of National Primary Drinking Water Regulations (NPDWR)” is used here to include violations of MCL, MRDL, treatment technique, monitoring, and testing procedure requirements.
4. Failure to test for fecal coliform or E. coli is a Tier 1 violation if testing is not done after any repeat sample tests positive for coliform. All other total coliform monitoring and testing procedure violations are Tier 3 violations.
5. A supplier that violates the turbidity MCL of 5 NTU based on an average of measurements over two consecutive days must consult with the Agency within 24 hours after learning of the violation. Based on this consultation, the Agency may subsequently decide to issue a SEP issued pursuant to Section 611.110 that elevates the violation to a Tier 1 violation. If a system is unable to make contact with the Agency in the 24-hour period, the violation is automatically elevated to a Tier 1 violation.
6. A supplier with treatment technique a violation involving a single exceedance of a maximum turbidity limit under the Surface Water Treatment Rule (SWTR) or the Interim Enhanced Surface Water Treatment Rule (IESWTR) are required to consult with the Agency within 24 hours after learning of the violation. Based on this consultation, the Agency may subsequently decide to issue a SEP pursuant to Section 611.110 that elevates the violation to a Tier 1 violation. If a system is unable to make contact with the Agency in the 24-hour period, the violation is automatically elevated to a Tier 1 violation.
7. Most of the requirements of the Interim Enhanced Surface Water Treatment Rule (63 FR 69477) (Secs. 611.740-611.741, 611.743-611.744) become effective January 1, 2002 for a Subpart B supplier (surface water systems and ground water systems under the direct influence of surface water) that serves at least 10,000 persons. However, Section 611.742 is currently effective. The Surface Water Treatment Rule (SWTR) remains in effect for systems serving at least 10,000 persons even after 2002; the Interim Enhanced Surface Water Treatment Rule adds additional requirements and does not in many cases supercede the SWTR.
8. Failure to take a confirmation sample within 24 hours for nitrate or nitrite after an initial sample exceeds the MCL is a Tier 1 violation. Other monitoring violations for nitrate are Tier 3.
9. A subpart B community or non-transient non-community system supplier that serves 10,000 persons or more must comply with new DBP MCLs, disinfectant MRDLs, and related monitoring requirements beginning January 1, 2002. All other community and non-transient non-community systems must meet the MCLs and MRDLs beginning January 1, 2004. A Subpart B transient non-community system supplier serving 10,000 or more persons and using chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2002. A Subpart B transient non-community system supplier that serves fewer than 10,000 persons, which uses only ground water not under the direct influence of surface water, and which uses chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2004.
10. Section 611.310 will no longer apply after January 1, 2004.
11. Failure to monitor for chlorine dioxide at the entrance to the distribution system the day after exceeding the MRDL at the entrance to the distribution system is a Tier 2 violation.
12. If any daily sample taken at the entrance to the distribution system exceeds the MRDL for chlorine dioxide and one or more samples taken in the distribution system the next day exceed the MRDL, Tier 1 notification is required. A failure to take the required samples in the distribution system after the MRDL is exceeded at the entry point also triggers Tier 1 notification.
13. Some water suppliers must monitor for certain unregulated contaminants listed in Section 611.510.
14. This citation refers to Sections 1415 and 1416 of the federal Safe Drinking Water Act. Sections 1415 and 1416 require that “a schedule prescribed . . . for a public water system granted relief equivalent to a SDWA Section 1415 variance or a Section 1416 exemption shall require compliance by the system . . ..”
15. In addition to Sections 1415 and 1416 of the federal Safe Drinking Water Act, 40 CFR 142.307 specifies the items and schedule milestones that must be included in relief equivalent to a SDWA Section 1415 small system variance. In granting any from of relief from an NPDWR, the Board will consider all applicable federal requirements for and limitations on the State’s ability to grant relief consistent with federal law.
16. Other waterborne emergencies require a Tier 1 public notice under Section 611.902(a) for situations that do not meet the definition of a waterborne disease outbreak given in Section 611.101, but which still have the potential to have serious adverse effects on health as a result of short-term exposure. These could include outbreaks not related to treatment deficiencies, as well as situations that have the potential to cause outbreaks, such as failures or significant interruption in water treatment processes, natural disasters that disrupt the water supply or distribution system, chemical spills, or unexpected loading of possible pathogens into the source water.

National Primary Drinking Water Regulations (NPDWR): |
A. Microbiological Contaminants |
1a. Total coliform |
Zero |
See footnote 3 |
Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially-harmful, bacteria may be present. Coliforms were found in more samples than allowed and this was a warning of potential problems. |
1b. Fecal coliform/E. coli |
Zero |
Zero |
Fecal coliforms and E. coli are bacteria whose presence indicates that the water may be contaminated with human or animal wastes. Microbes in these wastes can cause short-term effects, such as diarrhea, cramps, nausea, headaches, or other symptoms. They may pose a special health risk for infants, young children, some of the elderly, and people with severely compromised immune systems. |
2a. Turbidity (MCL) 4 |
None |
1 NTU 5/5 NTU |

3. For a water supplier analyzing at least 40 samples per month, no more than 5.0 percent of the monthly samples may be positive for total coliforms. For a supplier analyzing fewer than 40 samples per month, no more than one sample per month may be positive for total coliforms.
4. There are various regulations that set turbidity standards for different types of systems, including Section 611.320, the 1989 Surface Water Treatment Rule, and the 1998 Interim Enhanced Surface Water Treatment Rule. The MCL for the monthly turbidity average is 1 NTU; the MCL for the 2-day average is 5 NTU for a supplier that is required to filter but have not yet installed filtration (Section 611.320).
5. “NTU” means nephelometric turbidity unit.
6. There are various regulations that set turbidity standards for different types of systems, including Section 611.320, the 1989 Surface Water Treatment Rule (SWTR), and the 1998 Interim Enhanced Surface Water Treatment Rule (IESWTR). A supplier subject to the Surface Water Treatment Rule (both filtered and unfiltered) may not exceed 5 NTU. In addition, in filtered systems, 95 percent of samples each month must not exceed 0.5 NTU in systems using conventional or direct filtration and must not exceed 1 NTU in systems using slow sand or diatomaceous earth filtration or other filtration technologies approved by the Agency.

8. There are various regulations that set turbidity standards for different types of systems, including Section 611.320, the 1989 Surface Water Treatment Rule (SWTR), and the 1998 Interim Enhanced Surface Water Treatment Rule (IESWTR). For a supplier subject to the IESWTR (systems serving at least 10,000 people, using surface water or ground water under the direct influence of surface water), that use conventional filtration or direct filtration, after January 1, 2002, the turbidity level of a system’s combined filter effluent may not exceed 0.3 NTU in at least 95 percent of monthly measurements, and the turbidity level of a system’s combined filter effluent must not exceed 1 NTU at any time. A supplier subject to the IESWTR using technologies other than conventional, direct, slow sand, or diatomaceous earth filtration must meet turbidity limits set by the Agency.
9. The bacteria detected by heterotrophic plate count (HPC) are not necessarily harmful. HPC is simply an alternative method of determining disinfectant residual levels. The number of such bacteria is an indicator of whether there is enough disinfectant in the distribution system.
10. SWTR and IESWTR treatment technique violations that involve turbidity exceedances may use the health effects language for turbidity instead.
11. Millions of fibers per liter.
12. Action Level = 0.015 mg/L.
13. Action Level = 1.3 mg/L.
14. Millirems per years.
15. Picocuries per liter.
16. A surface water system supplier or a ground water system supplier under the direct influence of surface water are regulated under Subpart B of this Part. A Supbart B community water system supplier or a non-transient non-community system supplier that serves 10,000 or more persons must comply with DBP MCLs and disinfectant maximum residual disinfectant levels (MRDLs) beginning January 1, 2002. All other community and non-transient noncommunity system suppliers must meet the MCLs and MRDLs beginning January 1, 2004. Subpart B transient non-community system suppliers serving 10,000 or more persons and using chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2002. Subpart B transient non-community system suppliers serving fewer than 10,000 persons and systems using only ground water not under the direct influence of surface water and using chlorine dioxide as a disinfectant or oxidant must comply with the chlorine dioxide MRDL beginning January 1, 2004.
17. The MCL of 0.10 mg/l for TTHMs is in effect until January 1, 2002 for a Subpart B community water system supplier serving 10,000 or more persons. This MCL is in effect until January 1, 2004 for community water systems with a population of 10,000 or more using only ground water not under the direct influence of surface water. After these deadlines, the MCL will be 0.080 mg/l. On January 1, 2004, a supplier serving less than 10,000 will have to comply with the new MCL as well.
18. The MCL for total trihalomethanes is the sum of the concentrations of the individual trihalomethanes.
19. The MCL for haloacetic acids is the sum of the concentrations of the individual haloacetic acids.
20. “MRDLG” means maximum residual disinfectant level goal.
21. “MRDL” means maximum residual disinfectant level.

A water supplier may further reduce the frequency of monitoring for water quality parameters at the tap from annually to once every three years if they have maintained the range of values for water quality parameters reflecting optimal corrosion control during three consecutive years of annual monitoring. A water supplier may accelerate to triennial monitoring for water quality parameters at the tap if they have maintained 90th percentile lead levels less than or equal to 0.005 mg/L, 90th percentile copper levels less than or equal to 0.65 mg/L, and the range of water quality parameters designated by the Agency under Section 611.352(f) as representing optimal corrosion control during two consecutive six-month monitoring periods.
