Adopted Rule. Final Order.
OPINION AND ORDER OF THE BOARD (by N.J. Melas):
The Board today adopts amendments to the Illinois regulations that are “identical in substance” to drinking water regulations adopted by the United States Environmental Protection Agency (USEPA). The USEPA rules 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) (1994)). This docket includes federal SDWA amendments that USEPA adopted in the period of January 1, 2002 through June 30, 2002.
Sections 7.2 and 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and 17.5 (2000)) provide for quick adoption by the Board 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 SDWA. 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 (2000)) 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.
The order segment of this opinion and order sets forth the text of the adopted amendments. That text begins below on page 34. The adopted amendments will be filed with the Office of the Secretary of State no later than January 14, 2003.
FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING
The following briefly summarizes the federal actions considered in this rulemaking.
Docket R03-4: January 1, 2002 through June 30, 2002 SDWA Amendments
USEPA amended the federal SDWA regulations on only two occasions during the period January 1, 2002 through June 30, 2002. These are summarized below:
January 14, 2002 (67 Fed. Reg. 1812)
USEPA adopted the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR). The goals of the LT1ESWTR are to improve control of risks to human health posed by microbial pathogens and to balance the risks posed by disinfection byproducts. The LT1ESWTR applies to systems using surface water or groundwater under the direct influence of surface water that serve fewer than 10,000 persons. The LT1ESWTR complements the earlier Interim Enhanced Surface Water Treatment Rule (IESWTR) that applied to larger systems. (USEPA adopted the IESWR on December 16, 1998 (at 63 Fed. Reg. 69478), and the Board made corresponding amendments to the Illinois drinking water regulations in SDWA Update, USEPA Regulations (July 1, 1998 through December 31, 1998), R99-12 (July 22, 1999).)
March 12, 2002 (67 Fed. Reg. 11046)
USEPA adopted a direct final rule that delayed the deadline for reporting unregulated contaminants monitoring results obtained before May 13, 2002.
No Board Action on One Federal Action
One of the federal actions that occurred during the period of January 1, 2002 through June 30, 2002 will require no action on the part of the Board to amend the Illinois drinking water regulations. No action will be necessary on the federal March 12, 2002 (67 Fed. Reg. 11046) unregulated contaminants monitoring rule. As stated in SDWA Update, USEPA Regulations (July 1, 1999 through December 31, 1999) (Aug. 24, 2000), R00-10, USEPA and the Agency have both commented that the unregulated contaminant monitoring provisions are not segments of the federal SDWA rules that the Board is required to adopt and maintain.
No Later SDWA (Drinking Water) Amendments of Interest
The Board engages in ongoing monitoring of federal actions. As of the date of this opinion and accompanying order, the Board has not identified any USEPA actions since June 30, 2002 that further amend the SDWA rules.
When the Board observes an action outside the nominal timeframe of a docket that would require expedited consideration in the pending docket, the Board will expedite consideration of those amendments. Federal actions that could warrant expedited consideration include those that directly affect the amendments involved in this docket, those for which compelling reasons would warrant consideration as soon as possible and those for which the Board has received a request for expedited consideration.

PUBLIC COMMENTS
The Board adopted a proposal for public comment in this matter on September 5, 2002. A Notice of Proposed Amendments appeared in the October 25, 2002 issue of the Illinois Register, at 26 Ill. Reg. 15176. The Board received public comments on the proposal for 45 days after the date of publication, until December 9, 2002. During the public comment period, the Board a number of suggestions for revisions and corrections from the Joint Committee on Administrative Rules (JCAR). The Board further received the following public comment:
| PC 1 | Rita Garner, Ground Water and Drinking Water Branch, USEPA Region V, (dated December 9, 2002) |
| PC 2 | Stephen C. Ewart, Deputy Counsel, Agency, Division of Legal Counsel (dated December 13, 2002) |
In PC 1 and PC 2, USEPA and the Agency offered a small number of minor corrections to the text of the amendments. None of the corrections had a substantive effect. The Board will refrain from discussion of the minor suggestions received from the Agency, USEPA, and JCAR, but the corrections made in response are itemized in the list that begins on page 29 of this opinion and order. The Agency’s request that the Board alter the effective date of the rule is not a minor suggestion, and the Board considers that request in the following discussion.
DISCUSSION
The following discussion begins with a description of the types of deviations the Board makes from the literal text of federal regulations in adopting identical-in-substance rules. It is followed by a discussion of the amendments and actions undertaken in direct response to the federal actions involved in this proceeding. This first series of discussions is organized by federal subject matter, generally appearing in chronological order of the relevant Federal Register notice involved. Finally, this discussion closes with a description of the amendments and actions that are not directly derived from the federal actions.
Discussion of the Federal Action
The Long-Term 1 Enhanced Surface Water Rule—Sections 611.101, 611.160, 611.220, 611.250, 611.740, 611.883, 611.902, 611.903, and Subpart X and Appendices G and H to Part 611
On January 14, 2002 (67 Fed. Reg. 1812), USEPA adopted the LT1ESWTR. The recent LT1SWTR is a companion to the December 16, 1998 (63 Fed. Reg. 69478) interim enhanced surface water rule (IESWTR). The 1998 IESWTR imposed requirements on larger water systems (those providing water to 10,000 persons or more) that use surface water or groundwater under the direct influence of surface water. USEPA established the filtration and disinfection requirements of the 1998 IESWTR in a new subpart P to 40 C.F.R. 141 (40 C.F.R. 141.170 through 141.75, corresponding with Subpart R to 35 Ill. Adm. Code 611; Sections 611.740 through 611.745). The 2002 LT1ESWTR extends enhanced filtration and disinfection requirements to smaller public water supplies (those serving fewer than 10,000 persons). USEPA adopted the 2002 LT1ESWTR as a new subpart T to 40 C.F.R. 141 (40 C.F.R. 141.500 through 141.571, corresponding with new Subpart X to 35 Ill. Adm. Code 611; Sections 611.950 through 611.957).
The Board incorporated the January 14, 2002 federal amendments into the Illinois drinking water regulations with only minimal changes to their text. The principal changes made related to the style and structure of the LT1ESWTR. USEPA chose a more informal approach to drafting and codification of this rule. USEPA divided its new subpart T into eight segments bearing sub-headings. In each segment are two to seven short sections that are set forth in a question-and-answer format. USEPA freely used the second person and a question-and-answer format in setting forth the rules.
The Board has altered these aspects of the federal text. First, a corresponding use of Subpart sub-headings is not allowed in the Illinois Administrative Code. Some of the new federal provisions are very short, with many no more that one or two sentences long. For this reason, the Board has used the federal sub-headings as the basis for consolidating this new Subpart into eight new Sections, rather than the 32 sections added by USEPA to federal part 141. Second, the Board strongly prefers not to use the second person and the question-and-answer format that USEPA seems to favor in drafting rules. The Board has changed the rules so that the second person does not appear, and so that the rules affirmatively impose requirements on a “supplier.” The Board believes that this reduces the possibility of any mistake that the rules are advisory, rather than compulsory.
The Board has made another series of changes in the structure of the rules. USEPA included seven short tables in its rules that set forth what is required. The Board changed this structure by incorporating the tabulated requirements into the standard paragraph format that the Board prefers for rules. The Board was able to make this structural change with only minimal alterations to the text of the rules, such as introducing the material from the column headings into the text of the requirements and separating material from the various columns with a comma.
The table that appears below on page 7 itemizes the several changes made by the Board to the text of the federal rules. The Board requested public comment on the incorporation of the January 14, 2002 federal LT1SWTR. The Board specifically requested comment on the several structural changes made to the text. In PC 1, PC 2, and the suggestions submitted by JCAR, the Board received a limited number of recommendations for corrections to the amendments, but none of those recommendations had a substantive effect. The table that begins on page 29 of this opinion and order lists the corrections made.
Fulfilling one Agency request in PC 2, however, has a substantive effect on implementation of the rule, and the Board discusses that request here. The Agency has requested that the Board change the effective date for the LT1SWR from January 14, 2005, to the first of a month. The Agency noted that the compliance demonstrations required under the rule are made on a calendar-month basis, and an implementation deadline in the middle of the month thwarts this regulatory scheme. The Board agrees with the Agency, and the adopted rule uses January 1, 2005 as the implementation deadline for the Illinois rule.
The Board has chosen the January 1, 2005 date as the best permissible alternative. If USEPA should amend its regulations to change the federal effective date, the Board will make any necessary change in the Illinois regulation at that time.
General Revisions and Deviations from the Federal Text
In incorporating the federal rules into the Illinois system, some deviation from the federal text is unavoidable. This deviation arises primarily through differences between the federal and state regulatory structure and systems. Some deviation also arises through errors in and problems with the federal text itself. The Board conforms the federal text to the Illinois rules and regulatory scheme and corrects errors that we see in the text as we engage in these routine update rulemakings.
In addition to the amendments derived from federal amendments, the Board often finds it necessary to alter the text of various passages of the existing rules as provisions are opened for update in response to USEPA actions. This involves correcting deficiencies, clarifying provisions, and making other changes that are necessary to establish a clear set of rules that closely parallel the corresponding federal requirements within the codification scheme of the Illinois Administrative Code.
The Board updates the citations to the Code of Federal Regulations to the most recent version available. As of the date of this opinion, the most recent version of the Code of Federal Regulations available to the Board is the July 1, 2002 version. Thus, the Board has updated all citations to the 2002 version, adding references to later amendments using their appropriate Federal Register citation, where necessary.
The Board substituted “or” for “/” in most instances where this appeared in the federal base text, using “and” where more appropriate. The Board further used this opportunity to make a number of corrections to punctuation, grammar, spelling, and cross-reference format throughout the opened text. The Board changed “who” to “that” and “he” or “she” to “it,” where the person to which the regulation referred was not necessarily a natural person, or to “he or she,” where a natural person was evident; changed “which” to “that” for restrictive relative clauses; substituted “must” for “shall”; capitalized the section headings and corrected their format where necessary; and corrected punctuation within sentences.
In addition, the federal rules have been edited to establish a uniform usage throughout the Board’s regulations. For example, with respect to “shall,” “will,” and “may,” “must” is used when an action is required by the rule, without regard to whether the action is required of the subject of the sentence or not. “Shall” is no longer used, since it is not used in everyday language. Thus, where a federal rule uses “shall,” the Board usually substitutes “must.” An exception to this would be that the Board renders such phrases as “no person shall” as “no person may.” This is a break from our former practice where “shall” was used when the subject of a sentence has a duty to do something. “Will” is used when the Board obliges itself to do something. “May” is used when choice of a provision is optional, with the exception of proscriptive use of may as indicated in the above example. “Or” is used rather than “and/or,” and denotes “one or both.” “Either . . . or” denotes “one but not both.” “And” denotes “both.”
The JCAR has requested that the Board refer to the United States Environmental Protection Agency in the same manner throughout all of our bodies of regulations—i.e., air, water, drinking water, Resource Conservation and Recovery Act (RCRA) Subtitle D (municipal solid waste landfill), RCRA Subtitle C (hazardous waste), underground injection control (UIC), etc. The Board has decided to refer to the United States Environmental Protection Agency as “USEPA.” The Board will continue this conversion in future rulemakings, as additional sections become open to amendment. The Board will further convert “EPA” used in federal text to “USEPA,” where USEPA is clearly intended.
The Board has assembled tables to aid in the location of these alterations and to briefly outline their intended purpose. The tables set forth the miscellaneous deviations from the federal text and corrections to the pre-amended base text of the rules in detail. The tables are set forth and explained beginning at page 7 of this opinion. There is no further discussion of most of the deviations and revisions elsewhere in this opinion.
Agency or Board Action
Section 7.2(a)(5) of the Act requires the Board to specify portions of the program USEPA over which will retain decision making authority. Based on the general division of functions within the Act and other Illinois statutes, the Board is also to specify which State agency is to make decisions.
In situations in which the Board has determined that USEPA will retain decision-making authority, the Board has replaced “Regional Administrator” with USEPA, so as to avoid specifying which office within USEPA is to make a decision.
In some identical-in-substance rules, certain decisions pertaining to a permit application are not appropriate for the Agency to consider. In determining the general division of authority between the Agency and the Board, the following factors should be considered:
| 1. | Whether the person making the decision is applying a Board regulation, or taking action contrary to a Board regulation--i.e., the decision is effectively granting relief from a Board regulation. It generally takes some form of Board action to grant relief from a Board regulation. |
| 2. | Whether there is a clear standard for action such that the Board can give meaningful review to an Agency decision. |
| 3. | Whether the action would result in exemption from the permit requirement itself. If so, Board action is generally required. |
| 4. | Whether the decision amounts to “determining, defining or implementing environmental control standards” within the meaning of Section 5(b) of the Act. If so, it must be made by the Board. |
There are four common classes of Board decisions: variance, adjusted standard, site-specific rulemaking, and enforcement. The first three are methods by which a regulation can be temporarily postponed (variance) or adjusted to meet specific situations (adjusted standard or site-specific rulemaking). There often are differences in the nomenclature for these decisions between the USEPA and Board regulations.
Discussion of Miscellaneous Housekeeping Amendments
The tables below list numerous corrections and amendments that are not based on current federal amendments. The first table (beginning immediately below) includes deviations made in these amendments from the verbatim text of the federal amendments. The second table (beginning below at page 26) contains corrections and clarifications that the Board made in the base text involved in these amendments. The amendments listed in this second table are not directly derived from the current federal amendments. Table 3 (beginning on page 29 below) is a listing of revisions made to the text of the amendments from that proposed and set forth in the Board’s opinion and order of October 3, 2002. Table 3 indicates the changes made, as well as the source that suggested each of the changes. Table 4 (beginning on page 33 below) indicates suggested revisions that the Board has not made in adopting these amendments. Each entry gives a brief explanation why the Board did not incorporate the suggested change. Some of the entries in these tables are discussed further in appropriate segments of the general discussion beginning at page 4 of this opinion.

As used in this Part, the term:
“Act” means the Environmental Protection Act [415 ILCS 5].
“Agency” means the Illinois Environmental Protection Agency.
BOARD NOTE: The Department of Public Health regulates non-community water supplies (“non-CWSs,” including non-transient, non-community water supplies (“NTNCWSs”) and transient non-community water supplies (“transient non-CWSs”)). For the purposes of regulation of supplies by Public Health by reference to this Part, “Agency” will mean the Department of Public Health.
“Ai” means “inactivation ratio.”
“Approved source of bottled water,” for the purposes of Section 611.130(e)(4), means a source of water and the water therefrom, whether it be from a spring, artesian well, drilled well, municipal water supply, or any other source, that has been inspected and the water sampled, analyzed, and found to be a safe and sanitary quality according to applicable laws and regulations of State and local government agencies having jurisdiction, as evidenced by the presence in the plant of current certificates or notations of approval from each government agency or agencies having jurisdiction over the source, the water it bottles, and the distribution of the water in commerce.
BOARD NOTE: Derived from 40 CFR 142.62(g)(2) and 21 CFR 129.3(a) (2000) (2002). The Board cannot compile an exhaustive listing of all federal, state, and local laws to which bottled water and bottling water may be subjected. However, the statutes and regulations of which the Board is aware are the following: the Illinois Food, Drug and Cosmetic Act [410 ILCS 620], the Bottled Water Act [815 ILCS 310], the DPH Water Well Construction Code (77 Ill. Adm. Code 920), the DPH Water Well Pump Installation Code (77 Ill. Adm. Code 925), the federal bottled water quality standards (21 CFR 103.35), the federal drinking water processing and bottling standards (21 CFR 129), the federal Current Good Manufacturing Practice in Manufacturing, Packing, or Holding Human Food (21 CFR 110), the federal Fair Packaging and Labeling Act (15 USC 1451 et seq.), and the federal Fair Packaging and Labeling regulations (21 CFR 201).
“Best available technology” or “BAT” means the best technology, treatment techniques or other means that USEPA has found are available for the contaminant in question. BAT is specified in Subpart F of this Part.
“Board” means the Illinois Pollution Control Board.
“CAS No.” means “Chemical Abstracts Services Number.”
“CT” or “CTcalc” is the product of “residual disinfectant concentration” (RDC or C) in mg/L determined before or at the first customer, and the corresponding “disinfectant contact time” (T) in minutes. If a supplier applies disinfectants at more than one point prior to the first customer, it must determine the CT of each disinfectant sequence before or at the first customer to determine the total percent inactivation or “total inactivation ratio.” In determining the total inactivation ratio, the supplier must determine the RDC of each disinfection sequence and corresponding contact time before any subsequent disinfection application points. (See “CT99.9.”)
“CT99.9” is the CT value required for 99.9 percent (3-log) inactivation of Giardia lamblia cysts. CT99.9 for a variety of disinfectants and conditions appear in Tables 1.1-1.6, 2.1 and 3.1 of Section 611.Appendix B. (See “Inactivation Ratio.”)
BOARD NOTE: Derived from the definition of “CT” in 40 CFR 141.2 (2000).
“Coagulation” means a process using coagulant chemicals and mixing by which colloidal and suspended materials are destabilized and agglomerated into flocs.
“Community water system” or “CWS” means a public water system (PWS) that serves at least 15 service connections used by year-round residents or regularly serves at least 25 year-round residents.
BOARD NOTE: This definition differs slightly from that of Section 3.05 of the Act.
“Compliance cycle” means the nine-year calendar year cycle during which public water systems (PWSs) must monitor. Each compliance cycle consists of three three-year compliance periods. The first calendar cycle begins January 1, 1993, and ends December 31, 2001; the second begins January 1, 2002, and ends December 31, 2010; the third begins January 1, 2011, and ends December 31, 2019.
“Compliance period” means a three-year calendar year period within a compliance cycle. Each compliance cycle has three three-year compliance periods. Within the first compliance cycle, the first compliance period runs from January 1, 1993, to December 31, 1995; the second from January 1, 1996, to December 31, 1998; the third from January 1, 1999, to December 31, 2001.
“Comprehensive performance evaluation” or “CPE” is a thorough review and analysis of a treatment plant’s performance-based capabilities and associated administrative, operation, and maintenance practices. It is conducted to identify factors that may be adversely impacting a plant’s capability to achieve compliance and emphasizes approaches that can be implemented without significant capital improvements.
BOARD NOTE: The final sentence of the definition of “comprehensive performance evaluation” in 40 CFR 141.2 is codified as Section 611.160(a)(2), since it contains substantive elements that are more appropriate in a substantive provision.
“Confluent growth” means a continuous bacterial growth covering the entire filtration area of a membrane filter or a portion thereof, in which bacterial colonies are not discrete.
“Contaminant” means any physical, chemical, biological or radiological substance or matter in water.
“Conventional filtration treatment” means a series of processes including coagulation, flocculation, sedimentation, and filtration resulting in substantial particulate removal.
“Diatomaceous earth filtration” means a process resulting in substantial particulate removal in which:
A precoat cake of diatomaceous earth filter media is deposited on a support membrane (septum); and
While the water is filtered by passing through the cake on the septum, additional filter media known as body feed is continuously added to the feed water to maintain the permeability of the filter cake.
“Direct filtration” means a series of processes including coagulation and filtration but excluding sedimentation resulting in substantial particulate removal.
“Disinfectant” means any oxidant, including but not limited to chlorine, chlorine dioxide, chloramines, and ozone added to water in any part of the treatment or distribution process, that is intended to kill or inactivate pathogenic microorganisms.
“Disinfectant contact time” or “T” means the time in minutes that it takes for water to move from the point of disinfectant application or the previous point of RDC measurement to a point before or at the point where RDC is measured.
Where only one RDC is measured, T is the time in minutes that it takes for water to move from the point of disinfectant application to a point before or at the point where RDC is measured.
Where more than one RDC is measured, T is:
For the first measurement of RDC, the time in minutes that it takes for water to move from the first or only point of disinfectant application to a point before or at the point where the first RDC is measured, and
For subsequent measurements of RDC, the time in minutes that it takes for water to move from the previous RDC measurement point to the RDC measurement point for which the particular T is being calculated.
T in pipelines must be calculated based on “plug flow” by dividing the internal volume of the pipe by the maximum hourly flow rate through that pipe.
T within mixing basins and storage reservoirs must be determined by tracer studies or an equivalent demonstration.
“Disinfection” means a process that inactivates pathogenic organisms in water by chemical oxidants or equivalent agents.
“Disinfection byproduct” or “DBP” means a chemical byproduct that forms when disinfectants used for microbial control react with naturally occurring compounds already present in source water. DBPs include, but are not limited to, bromodichloromethane, bromoform, chloroform, dichloroacetic acid, bromate, chlorite, dibromochloromethane, and certain haloacetic acids.
“Disinfection profile” is a summary of daily Giardia lamblia inactivation through the treatment plant. The procedure for developing a disinfection profile is contained in Section 611.742.

“Enhanced coagulation” means the addition of sufficient coagulant for improved removal of disinfection byproduct (DBP) precursors by conventional filtration treatment.
“Enhanced softening” means the improved removal of disinfection byproduct (DBP) precursors by precipitative softening.
“Entry point” means a point just downstream of the final treatment operation, but upstream of the first user and upstream of any mixing with other water. If raw water is used without treatment, the “entry point” is the raw water source. If a PWS receives treated water from another PWS, the “entry point” is a point just downstream of the other PWS, but upstream of the first user on the receiving PWS, and upstream of any mixing with other water.
“Filter profile” is a graphical representation of individual filter performance, based on continuous turbidity measurements or total particle counts versus time for an entire filter run, from startup to backwash inclusively, that includes an assessment of filter performance while another filter is being backwashed.
“Filtration” means a process for removing particulate matter from water by passage through porous media.
“Flocculation” means a process to enhance agglomeration or collection of smaller floc particles into larger, more easily settleable particles through gentle stirring by hydraulic or mechanical means.

| 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 A of this Part for lead, copper, or both. |

| 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; |
| 3) | A brief status report on the steps the CWS is taking to install treatment, find alternative sources of water, or otherwise comply with the terms and schedules of the variance, adjusted standard, or site-specific rule; and |
| 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; |

| 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 languages regarding the importance of the report or contain a telephone number or address where such residents may contact the system to obtain a translated copy of the report or assistance in the appropriate language. |
| 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. |

| 5) | Violation of the turbidity MCL under Section 141.13(b), where the Agency determines after consultation that a Tier 1 notice is required or where consultation does not take place within 24 hours after the supplier learns of the violation; |
| 6) | Violation of the Surface Water Treatment Rule (SWTR), |
| 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 |
| 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. |

| 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 |
| 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, |
| 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) | 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) | 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). |

SUBPART X--ENHANCED FILTRATION AND DISINFECTION--SYSTEMS SERVING FEWER THAN 10,000 PEOPLE
| Section 611.950 | General Requirements |
| a) | The requirements of this Subpart X constitute national primary drinking water regulations. These regulations establish requirements for filtration and disinfection that are in addition to criteria under which filtration and disinfection are required under Subpart B of this Part. The regulations in this Subpart X establish or extend treatment technique requirements in lieu of maximum contaminant levels for the following contaminants: Giardia lamblia, viruses, heterotrophic plate count bacteria, Legionella, Cryptosporidium, and turbidity. The treatment technique requirements consist of installing and properly operating water treatment processes that reliably achieve the following: |
| 1) | At least 99 percent (2 log) removal of Cryptosporidium between a point where the raw water is not subject to recontamination by surface water runoff and a point downstream before or at the first customer for filtered systems, or Cryptosporidium control under the watershed control plan for unfiltered systems; and |
| 2) | Compliance with the profiling and benchmark requirements in Sections 611.953 and 611.954. |
| b) | Applicability of the Subpart X requirements. A supplier is subject to these requirements if the following is true of its system: |
| 1) | Is a public water system; |
| 2) | Uses surface water or groundwater under the direct influence of surface water as a source; and |
| 3) | Serves fewer than 10,000 persons. |
| c) | Compliance deadline. A supplier must comply with these requirements in this Subpart X beginning January 1, 2005, except where otherwise noted. |
| d) | Subpart X requirements. There are seven requirements of this Subpart X, and a supplier must comply with all requirements that are applicable to its system. These requirements are the following: |
| 1) | The supplier must cover any finished water reservoir that the supplier began to construct on or after March 15, 2002, as described in Section 611.951; |
| 2) | If the supplier’s system is an unfiltered system, the supplier must comply with the updated watershed control requirements described in Section 611.952; |
| 3) | If the supplier’s system is a community or non-transient non-community water system the supplier must develop a disinfection profile, as described in Section 611.953; |
| 4) | If the supplier’s system is considering making a significant change to its disinfection practices, the supplier must develop a disinfection benchmark and consult with the Agency for approval of the change, as described in Section 611.954; |
| 5) | If the supplier’s system is a filtered system, the supplier must comply with the combined filter effluent requirements, as described in Section 611.955; |
| 6) | If the supplier’s system is a filtered system that uses conventional or direct filtration, the supplier must comply with the individual filter turbidity requirements, as described in Section 611.956; and |
| 7) | The supplier must comply with the applicable reporting and recordkeeping requirements, as described in Section 611.957. |

| Section 611.952 | Additional Watershed Control Requirements for Unfiltered Systems |
| a) | Applicability. A Subpart B system supplier that serves fewer than 10,000 persons which does not provide filtration must continue to comply with all of the filtration avoidance criteria in Sections 611.211 and 611.230 through 611.233, as well as the additional watershed control requirements in subsection (b) of this Section. |
| b) | Requirements to avoid filtration. A supplier must take any additional steps necessary to minimize the potential for contamination by Cryptosporidium oocysts in the source water. A watershed control program must fulfill the following for Cryptosporidium: |
| 1) | The program must identify watershed characteristics and activities that may have an adverse effect on source water quality; and |
| 2) | The program must monitor the occurrence of activities that may have an adverse effect on source water quality. |
| c) | Determination of adequacy of control requirements. During an onsite inspection conducted under the provisions of Section 611.232(c), the Agency must determine whether a watershed control program is adequate to limit potential contamination by Cryptosporidium oocysts. The adequacy of the program must be based on the comprehensiveness of the watershed review; the effectiveness of the program to monitor and control detrimental activities occurring in the watershed; and the extent to which the supplier has maximized land ownership or controlled land use within the watershed. |

| Section 611.953 | Disinfection Profile |
| a) | Applicability. A disinfection profile is a graphical representation of a system’s level of Giardia lamblia or virus inactivation measured during the course of a year. A Subpart B community or non-transient non-community water system that serves fewer than 10,000 persons must develop a disinfection profile unless the Agency, by an SEP issued pursuant to Section 611.110, determines that a profile is unnecessary. The Agency may approve the use of a more representative data set for disinfection profiling than the data set required under subsections (c) through (g) of this Section. |
| b) | Determination that a disinfection profile is not necessary. The Agency may only determine that a disinfection profile is not necessary if the system’s TTHM and HAA5 levels are below 0.064 mg/L and 0.048 mg/L, respectively. To determine these levels, TTHM and HAA5 samples must have been collected after January 1, 1998, during the month with the warmest water temperature, and at the point of maximum residence time in the distribution system. |
| c) | Development of a disinfection profile. A disinfection profile consists of the following three steps: |
| 1) | First, the supplier must collect data for several parameters from the plant, as discussed in subsection (d) of this Section, over the course of 12 months. If the supplier serves between 500 and 9,999 persons it must begin to collect data no later than July 1, 2003. If the supplier serves fewer than 500 persons, it must begin to collect data no later than January 1, 2004. |
| 2) | Second, the supplier must use this data to calculate weekly log inactivation as discussed in subsections (e) and (f) of this Section; and |
| 3) | Third, the supplier must use these weekly log inactivations to develop a disinfection profile as specified in subsection (g) of this Section. |
| d) | Data required for a disinfection profile. A supplier must monitor the following parameters to determine the total log inactivation using the analytical methods in Section 611.231, once per week on the same calendar day, over 12 consecutive months: |
| 1) | The temperature of the disinfected water at each residual disinfectant concentration sampling point during peak hourly flow; |
| 2) | If a supplier uses chlorine, the pH of the disinfected water at each residual disinfectant concentration sampling point during peak hourly flow; |
| 3) | The disinfectant contact times (“T”) during peak hourly flow; and |
| 4) | The residual disinfectant concentrations (“C”) of the water before or at the first customer and prior to each additional point of disinfection during peak hourly flow. |
| e) | Calculations based on the data collected. The supplier must calculate the total inactivation ratio as follows, and multiply the value by 3.0 to determine log inactivation of Giardia lamblia: |
| 1) | If the supplier uses only one point of disinfectant application, it must determine either of the following: |
| A) | One inactivation ratio (CTcalc/CT99.9) before or at the first customer during peak hourly flow, or |
| B) | Successive CTcalc/CT99.9 values, representing sequential inactivation ratios, between the point of disinfectant application and a point before or at the first customer during peak hourly flow. Under this alternative, the supplier must calculate the total inactivation ratio by determining CTcalc/CT99.9 for each sequence and then adding the CTcalc/CT99.9 values together to determine ∑CTcalc/CT99.9. |
| 2) | If the supplier uses more than one point of disinfectant application before the first customer, it must determine the CTcalc/CT99.9 value of each disinfection segment immediately prior to the next point of disinfectant application, or for the final segment, before or at the first customer, during peak hourly flow using the procedure specified in subsection (e)(1)(B) of this Section. |
| f) | Use of chloramines, ozone, or chlorine dioxide as a primary disinfectant. If a supplier uses chloramines, ozone, or chlorine dioxide for primary disinfection, the supplier must also calculate the logs of inactivation for viruses and develop an additional disinfection profile for viruses using methods approved by the Agency. |
| g) | Development and maintenance of the disinfection profile in graphic form. Each log inactivation serves as a data point in the supplier’s disinfection profile. A supplier will have obtained 52 measurements (one for every week of the year). This will allow the supplier and the Agency the opportunity to evaluate how microbial inactivation varied over the course of the year by looking at all 52 measurements (the supplier’s disinfection profile). The supplier must retain the disinfection profile data in graphic form, such as a spreadsheet, which must be available for review by the Agency as part of a sanitary survey. The supplier must use this data to calculate a benchmark if the supplier is considering changes to disinfection practices. |

(Source: Added at 26 Ill. Reg. ________, effective ______________________)
| Section 611.954 | Disinfection Benchmark |
| a) | Applicability. A Subpart B system supplier that is required to develop a disinfection profile under Section 611.953 must develop a disinfection benchmark if it decides to make a significant change to its disinfection practice. The supplier must consult with the Agency for approval before it can implement a significant disinfection practice change. |
| b) | Significant changes to disinfection practice. Significant changes to disinfection practice include: |
| 1) | Changes to the point of disinfection; |
| 2) | Changes to the disinfectants used in the treatment plant; |
| 3) | Changes to the disinfection process; or |
| 4) | Any other modification identified by the Agency. |
| c) | Considering a significant change. A supplier that is considering a significant change to its disinfection practice must calculate disinfection benchmark, as described in subsections (d) and (e) of this Section, and provide the benchmarks to the Agency. A supplier may only make a significant disinfection practice change after consulting with the Agency for approval. A supplier must submit the following information to the Agency as part of the consultation and approval process: |
| 1) | A description of the proposed change; |
| 2) | The disinfection profile for Giardia lamblia (and, if necessary, viruses) and disinfection benchmark; |
| 3) | An analysis of how the proposed change will affect the current levels of disinfection; and |
| 4) | Any additional information requested by the Agency. |
| d) | Calculation of a disinfection benchmark. A supplier that is making a significant change to its disinfection practice must calculate a disinfection benchmark using the following procedure: |
| 1) | Step 1: Using the data that the supplier collected to develop the disinfection profile, determine the average Giardia lamblia inactivation for each calendar month by dividing the sum of all Giardia lamblia inactivations for that month by the number of values calculated for that month; and |
| 2) | Step 2: Determine the lowest monthly average value out of the 12 values. This value becomes the disinfection benchmark. |
| e) | If a supplier uses chloramines, ozone or chlorine dioxide for primary disinfection the supplier must calculate the disinfection benchmark from the data that the supplier collected for viruses to develop the disinfection profile in subsection (d) of this Section. This viral benchmark must be calculated in the same manner used to calculate the Giardia lamblia disinfection benchmark in subsection (d) of this Section. |

| Section 611.955 | Combined Filter Effluent Turbidity Limits |
| a) | Applicability. A Subpart B system supplier that serves fewer than 10,000 persons, which is required to filter, and which utilizes filtration other than slow sand filtration or diatomaceous earth filtration must meet the combined filter effluent turbidity requirements of subsections (b) through (d) of this Section . If the supplier uses slow sand or diatomaceous earth filtration the supplier is not required to meet the combined filter effluent turbidity limits of this Subpart X, but the supplier must continue to meet the combined filter effluent turbidity limits in Section 611.250. |
| b) | Combined filter effluent turbidity limits. A supplier must meet two strengthened combined filter effluent turbidity limits. |
| 1) | The first combined filter effluent turbidity limit is a “95th percentile” turbidity limit that a supplier must meet in at least 95 percent of the turbidity measurements taken each month. Measurements must continue to be taken as described in Sections 611.231 and 233. Monthly reporting must be completed according to Section 611.957(a). The following are the required limits for specific filtration technologies: |
| A) | For a system with conventional filtration or direct filtration, the 95th percentile turbidity value is 0.3 NTU. |
| B) | For a system with any other alternative filter technology, the 95th percentile turbidity value is a value (not to exceed 1 NTU) to be determined by the Agency, by an SEP issued pursuant to Section 611.110, based on the demonstration described in subsection (c) of this Section. |
| 2) | The second combined filter effluent turbidity limit is a “maximum” turbidity limit which a supplier may at no time exceed during the month. Measurements must continue to be taken as described in Sections 611.231 and 233. Monthly reporting must be completed according to Section 611.957(a). The following are the required limits for specific filtration technologies: |
| A) | For a system with conventional filtration or direct filtration, the maximum turbidity value is 1 NTU. |
| B) | For a system with any other alternative filter technology, the maximum turbidity value is a value (not to exceed 5 NTU) to be determined by the Agency, by an SEP issued pursuant to Section 611.110, based on the demonstration described in subsection (c) of this Section. |
| c) | Requirements for an alternative filtration system. |
| 1) | If a supplier’s system consists of alternative filtration(filtration other than slow sand filtration, diatomaceous earth filtration, conventional filtration, or direct filtration) the supplier is required to conduct a demonstration (see tables in subsection (b) of this Section). The supplier must demonstrate to the Agency, using pilot plant studies or other means, that its system’s filtration, in combination with disinfection treatment, consistently achieves: |
| A) | 99 percent removal of Cryptosporidium oocysts; |
| B) | 99.9 percent removal and/or inactivation of Giardia lamblia cysts; and |
| C) | 99.99 percent removal and/or inactivation of viruses. |
| 2) | This subsection (c)(2) corresponds with 40 CFR 141.552(b), which USEPA has designated as “reserved.” This statement maintains structural correspondence with the corresponding federal regulation. |
| d) | Requirements for a lime-softening system. If a supplier practices lime softening, the supplier may acidify representative combined filter effluent turbidity samples prior to analysis using a protocol approved by the Agency. |

| Section 611.956 | Individual Filter Turbidity Requirements |
| a) | Applicability. A Subpart B system supplier that serves fewer than 10,000 persons and utilizing conventional filtration or direct filtration must conduct continuous monitoring of turbidity for each individual filter in a supplier’s system. The following requirements apply to continuous turbidity monitoring: |
| 1) | Monitoring must be conducted using an approved method in Section 611.231; |
| 2) | Calibration of turbidimeters must be conducted using procedures specified by the manufacturer; |
| 3) | Results of turbidity monitoring must be recorded at least every 15 minutes; |
| 4) | Monthly reporting must be completed according to Section 611.957(a); and |
| 5) | Records must be maintained according to Section 611.957(b). |
| b) | Failure of turbidity monitoring equipment. If there is a failure in the continuous turbidity monitoring equipment, the supplier must conduct grab sampling every four hours in lieu of continuous monitoring until the turbidimeter is back on-line. The supplier has 14 days to resume continuous monitoring before a violation is incurred. |
| c) | Special requirements for systems with two or fewer filters. If a supplier’s system only consists of two or fewer filters, the supplier may conduct continuous monitoring of combined filter effluent turbidity in lieu of individual filter effluent turbidity monitoring. Continuous monitoring must meet the same requirements set forth in subsections (a)(1) through (a)(4) and (b) of this Section. |
| d) | Follow-up action. Follow-up action is required according to the following requirements: |
| 1) | If the turbidity of an individual filter (or the turbidity of combined filter effluent (CFE) for a system with two filters that monitor CFE in lieu of individual filters) exceeds 1.0 NTU in two consecutive recordings 15 minutes apart, the supplier must report to the Agency by the 10th of the following month and include the filter numbers, corresponding dates, turbidity values which exceeded 1.0 NTU, and the cause (if known) for the exceedences. |
| 2) | If a supplier was required to report to the Agency for three months in a row and turbidity exceeded 1.0 NTU in two consecutive recordings 15 minutes apart at the same filter (or CFE for systems with two filters that monitor CFE in lieu of individual filters), the supplier must conduct a self-assessment of the filters within 14 days of the day on which the filter exceeded 1.0 NTU in two consecutive measurements for the third straight month, unless a CPE, as specified in subsection (d)(3) of this Section, was required. A supplier that has a system with two filters which monitor CFE in lieu of individual filters must conduct a self assessment on both filters. The self-assessment must consist of at least the following components: assessment of filter performance, development of a filter profile, identification and prioritization of factors limiting filter performance, assessment of the applicability of corrections, and preparation of a filter self-assessment report. If a self-assessment is required, the date that it was triggered and the date that it was completed. |
| 3) | If a supplier was required to report to the Agency for two months in a row and turbidity exceeded 2.0 NTU in two consecutive recordings 15 minutes apart at the same filter (or CFE for systems with two filters that monitor CFE in lieu of individual filters), the supplier must arrange to have a comprehensive performance evaluation (CPE) conducted by the Agency or a third party approved by the Agency not later than 60 days following the day the filter exceeded 2.0 NTU in two consecutive measurements for the second straight month. If a CPE has been completed by the Agency or a third party approved by the Agency within the 12 prior months or the system and Agency are jointly participating in an ongoing comprehensive technical assistance (CTA) project at the system, a new CPE is not required. If conducted, a CPE must be completed and submitted to the Agency no later than 120 days following the day the filter exceeded 2.0 NTU in two consecutive measurements for the second straight month. |
| e) | Special individual filter monitoring for a lime-softening system. If a supplier’s system utilizes lime softening, the supplier may apply to the Agency for alternative turbidity exceedence levels for the levels specified in subsection (d) of this Section. The supplier must be able to demonstrate to the Agency that higher turbidity levels are due to lime carryover only, and not due to degraded filter performance. |

| Section 611.957 | Reporting and Recordkeeping Requirements |
| a) | Reporting. This Subpart X requires a supplier to report several items to the Agency. Subsections (a)(1) through (a)(4) of this Section describe the items that must be reported and the frequency of reporting. (The supplier is required to report the information described in subsections (a)(1) through (a)(4) of this Section, if it is subject to the specific requirement indicated.) |
| 1) | If a supplier is subject to the combined filter effluent requirements (Section 611.955), it must report as follows: |
| A) | The total number of filtered water turbidity measurements taken during the month, by the 10th of the following month. |
| B) | The number and percentage of filtered water turbidity measurements taken during the month that are less than or equal to the supplier’s required 95th percentile limit, by the 10th of the following month. |
| C) | The date and value of any turbidity measurements taken during the month that exceed the maximum turbidity value for the supplier’s filtration system, by the 10th of the following month. |
| 2) | If the supplier is subject to the individual filter turbidity requirements (Section 611.956), it must report as follows: |
| A) | The fact that the supplier’s system conducted individual filter turbidity monitoring during the month, by the 10th of the following month. |
| B) | The filter numbers, corresponding dates, and the turbidity values that exceeded 1.0 NTU during the month, by the 10th of the following month, but only if two consecutive measurements exceeded 1.0 NTU. |
| C) | If a self-assessment is required, the date that it was triggered and the date that it was completed, by the 10th of the following month (or 14 days after the self-assessment was triggered only if the self-assessment was triggered during the last four days of the month). |
| D) | If a CPE is required, the fact that the CPE is required and the date that it was triggered, by the 10th of the following month. |
| E) | A copy of completed CPE report, within 120 days after the CPE was triggered. |
| 3) | If the supplier is subject to the disinfection profiling (Section 611.953), it must report results of optional monitoring that show TTHM levels 0.064 mg/L and HAA5 levels 0.048 mg/L (only if the supplier wishes to forgo profiling) or that the supplier has begun disinfection profiling, as follows: |
| A) | For a supplier that serves 500-9,999 persons, by July 1, 2003; or |
| B) | For a supplier that serves fewer than 500 persons, by January 1, 2004. |
| 4) | If the supplier is subject to the disinfection benchmarking (Section 611.954), it must report a description of the proposed change in disinfection, its system’s disinfection profile for Giardia lamblia (and, if necessary, viruses) and disinfection benchmark, and an analysis of how the proposed change will affect the current levels of disinfection, anytime the supplier is considering a significant change to its disinfection practice. |
| b) | Recordkeeping. A supplier must keep several types of records based on the requirements of this Subpart X, in addition to recordkeeping requirements under Sections 611.261 and 611.262. Subsections (b)(1) through (b)(3) describe the necessary records, the length of time these records must be kept, and for which requirement the records pertain. (The supplier is required to maintain records described in subsections (b)(1) through (b)(3) of this Section, if it is subject to the specific requirement indicated.) |
| 1) | If the supplier is subject to the individual filter turbidity requirements (Section 611.956), it must retain the results of individual filter monitoring as necessary records for at least three years. |
| 2) | If the supplier is subject to disinfection profiling (Section 611.953), it must retain the results of its disinfection profile (including raw data and analysis) as necessary records indefinitely. |
| 3) | If the supplier is subject to disinfection benchmarking (Section 611.954), it must retain its disinfection benchmark (including raw data and analysis) as necessary records indefinitely. |

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 an SEP issued pursuant to Section 611.110. The Agency may, by an 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 an SEP pursuant to Section 611.110 that elevates the violation to a Tier 1 violation. If a supplier 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 a treatment technique violation involving a single exceedence of a maximum turbidity limit under the Surface Water Treatment Rule (SWTR), or the Interim Enhanced Surface Water Treatment Rule (IESWTR), or the Long Term 1 Enhanced Surface Water Treatment Rule 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 an SEP pursuant to Section 611.110 that elevates the violation to a Tier 1 violation. If a supplier 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 Fed. Reg. 69477 (December 16, 1998)) (Sections 611.740-611.741, 611.743-611.744) become effective January 1, 2002 for a Subpart B supplier (surface water systems and groundwater 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 a supplier 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. The arsenic MCL citations are effective January 23, 2006. Until then, the citations are Sections 611.330(b) and 611.612(c).
9. The arsenic Tier 3 violation MCL citations are effective January 23, 2006. Until then, the citations are Sections 611.100, 611.101, and 611.612.
10. 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.
11. The uranium MCL Tier 2 violation citations are effective December 8, 2003 for a CWS supplier.
12. The uranium Tier 3 violation citations are effective December 8, 2000 for a CWS supplier.
13. 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 that uses 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 groundwater 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.
14. Section 611.310 will no longer apply after January 1, 2004.
15. 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.
16. 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.
17. Some water suppliers must monitor for certain unregulated contaminants listed in Section 611.510.
18. 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 must require compliance by the system . . ..”
19. 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 form 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.
20. 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.

Appendix H--Endnotes
1. “MCLG” means maximum contaminant level goal.
2. “MCL” means maximum contaminant level.
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, and the 2002 Long Term 1 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 has 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), and the 2002 Long Term 1 Enhanced Surface Water Treatment Rule. 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.
7. “TT” means treatment technique.
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), and the 2002 Long Term 1 Enhanced Surface Water Treatment Rule. For a supplier subject to the IESWTR (systems serving at least 10,000 people, using surface water or groundwater 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. For a supplier subject to the LT1ESWTR (a supplier that serves fewer than 10,000 people, using surface water or groundwater under the direct influence of surface water) that uses conventional filtration or direct filtration, after January 1, 2005, the turbidity level of the supplier’s combined filter effluent may not exceed 0.3 NTU in at least 95 percent of monthly measurements, and the turbidity level of the supplier’s combined filter effluent must not exceed 1 NTU at any time. A supplier subject to the LT1ESWTR 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, and LT1ESWTR treatment technique violations that involve turbidity exceedences may use the health effects language for turbidity instead.
11. These arsenic values are effective January 23, 2006. Until then, the MCL is 0.05 mg/L and there is no MCLG.
12. Millions of fibers per liter.
13. Action Level = 0.015 mg/L.
14. Action Level = 1.3 mg/L.
15. Millirems per year.
16. Picocuries per liter.
17. The uranium MCL is effective December 8, 2003 for all community water systems.
18. A surface water system supplier or a groundwater system supplier under the direct influence of surface water is 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 non-community 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 groundwater 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.
19. 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 groundwater 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 fewer than 10,000 will have to comply with the new MCL as well.
20. The MCL for total trihalomethanes is the sum of the concentrations of the individual trihalomethanes.
21. The MCL for haloacetic acids is the sum of the concentrations of the individual haloacetic acids.
22. “MRDLG” means maximum residual disinfectant level goal.
23. “MRDL” means maximum residual disinfectant level.
