Adopted Rule. Final Order.

OPINION OF THE BOARD (by R.C. Flemal):

By this order, the Board is adopting amendments to the Illinois drinking water regulations that are identical in substance to amendments adopted by the United States Environmental Protection Agency (USEPA) to the federal Safe Drinking Water Act (SDWA) (42 U.S.C. §§ 300f et seq. (1994)) drinking water regulations. The federal amendments included in this docket include those adopted by USEPA during the period between January 1, 2001 and June 30, 2001. The Board has also included a number of amendments prompted by comments from the Joint Committee on Administrative Rules (JCAR), the Illinois Environmental Protection Agency (Agency), and USEPA.

These adopted amendments are based on a proposal for public comment adopted by the Board on October 4, 2001, for which a Notice of Proposed Amendments appeared in the October 26, 2001 issue of the Illinois Register. The Board has made only non-substantive changes to the proposal to public comments.

Under Sections 7.2 and 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and 17.5 (2000)), the Board today adopts amendments to the Illinois regulations that are “identical in substance” to drinking water regulations that USEPA adopted to implement Sections 1412(b), 1414(c), 1417(a), and 1445(a) of the federal SDWA (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and 300j-4(a) (1994)). The nominal timeframe of this docket includes federal SDWA amendments that USEPA adopted in the period January 1, 2001 through June 30, 2001.

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 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.

This opinion supports an order that the Board also adopts today. The Board will file the adopted amendments with the Office of the Secretary of State without delay.

Under Section 7.2(b) of the Act (415 ILCS 5/7.2(b) (2000)), the Board is required to complete the rulemaking action on these amendments within one year of the earliest federal amendments involved. As is outlined below, USEPA adopted the earliest federal amendments involved on January 16, 2001. Thus, the nominal deadline for completion of these amendments was January 16, 2002. On December 5, 2001, the Board received a request from USEPA that we extend the public comment period for an additional 30 days. The Board adopted an order on December 20, 2001, that extended the public comment period for the requested 30 days, until January 9, 2002. The Board also set forth reasons for delay in that order, as allowed under Section 7.2(b) of the Act, and the deadline for completion of the rulemaking activities in this matter was extended until February 22, 2002. A Notice of Public Information on Proposed Rules explaining the extension appeared in the January 4, 2002 issue of the Illinois Register (at 26 Ill. Reg. 247).

FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING

The following briefly summarizes the federal actions considered in this rulemaking.

Docket R02-1: January 1, 2001 through June 30, 2001 SDWA Amendments

USEPA amended the federal SDWA regulations on only one occasion during the period January 1, 2001 through June 30, 2001. This is summarized below:

66 Fed. Reg. 2273 (January 11, 2001)

USEPA approved analytical methods for 13 List 2 unregulated contaminants that suppliers must monitor. List 2 contaminants are those for which analytical methods are under refinement. USEPA also modified the requirements for implementation of monitoring for List 1 and List 2 contaminants.

66 Fed. Reg. 3466 (January 16, 2001)

By a direct final rule, USEPA approved the use of updated test procedures for determination of various contaminants in water and wastewater.

66 Fed. Reg. 3770 (January 16, 2001)

USEPA adopted minor amendments to the December 16, 1998 interim enhanced surface water rule (63 Fed. Reg. 69478) and the Stage 1 disinfectants and disinfection byproducts rule (63 Fed. Reg. 69390). USEPA had earlier adopted these amendments by a direct final rule on April 14, 2000 (65 Fed. Reg. 20304), but later withdrew those amendments as a result of adverse public comment on June 13, 2000 (65 Fed. Reg. 37052). USEPA again adopted the amendments with minor revisions after receiving additional public comments.

66 Fed. Reg. 6976 (January 22, 2001)

USEPA adopted National Primary Drinking Water Regulations for arsenic in drinking water. The standards included monitoring and reporting requirements for demonstrating compliance. The rules are applicable to non-transient non-community water systems and community water systems.

66 Fed. Reg. 9903 (February 12, 2001)

USEPA corrected its action of January 16, 2001 (66 Fed. Reg. 3770) pertaining to interim enhanced surface water rule and the Stage 1 disinfectants and disinfection byproducts rule.

66 Fed. Reg. 16134 (March 23, 2001)

USEPA delayed the effective date of the January 22, 2001 (66 Fed. Reg. 6976) arsenic rule for 60 days, until May 22, 2001.

66 Fed. Reg. 26795 (May 15, 2001)

USEPA withdrew its January 16, 2001 (66 Fed. Reg. 3466) direct final rule that approved the use of updated test procedures for determination of various contaminants in water and wastewater.

66 Fed. Reg. 27215 (May 16, 2001)

USEPA corrected its January 11, 2001 (66 Fed. Reg. 2273) approval of analytical methods for 13 List 2 unregulated contaminants that suppliers must monitor.

66 Fed. Reg. 28342 (May 22, 2001)

USEPA again delayed the effective date of the January 22, 2001 (66 Fed. Reg. 6976) arsenic rule to February 22, 2002. The January 22, 2004 effective date for compliance and new-source monitoring aspects of the rule remained unchanged.

66 Fed. Reg. 31086 (June 8, 2001)

USEPA adopted the filter backwash recycling rule. The rule regulates the return of recycled flows to the filtration process, which could potentially threaten the microbiologic integrity of the treatment process.

No Board Action on Certain Federal Actions

Some of the federal actions that occurred during the period of January 1, 2001 through June 30, 2001 will require no action on the part of the Board to amend the Illinois drinking water regulations. The Board summarizes those federal actions here:

1.	No action will be necessary on the federal January 11, 2001 (66 Fed. Reg. 2273) unregulated contaminants rules and the May 16, 2001 (66 Fed. Reg. 27215) approval of new methods for unregulated contaminants. As stated in SDWA Update, USEPA Regulations (July 1, 1999 through December 31, 1999), R00-10 (Aug. 24, 2000), 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.

2.	On May 15, 2001 (66 Fed. Reg. 26795), USEPA withdrew its direct final rule of January 16, 2001 (66 Fed. Reg. 3466) in which it approved updated test procedures for water contaminants. This withdrawal obviates Board action on the January 16, 2001 amendments (as well as the May 15, 2001 withdrawal of those amendments).

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, we have not identified any USEPA actions since June 30, 2001, 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.

Summary Tabulation of the Federal Actions Included in This Docket

January 16, 2001 (66 Fed. Reg. 3770)	Minor amendments to the December 16, 1998 interim enhanced surface water rule and Stage 1 disinfectants and disinfection byproducts rule.
January 22, 2001 (66 Fed. Reg. 6976)	National Primary Drinking Water Regulations for arsenic in drinking water.
February 12, 2001 (66 Fed. Reg. 9903)	USEPA corrected the January 16, 2001 amendments to the interim enhanced surface water rule and the Stage 1 disinfectants and disinfection byproducts rule.
March 23, 2001 (66 Fed. Reg. 16134)	USEPA delayed the effective date of the January 22, 2001 arsenic rule for 60 days, until May 22, 2001.
May 22, 2001 (66 Fed. Reg. 28342)	USEPA again delayed the effective date of the January 22, 2001 arsenic rule to February 22, 2002. (The January 22, 2004 effective date for compliance and new-source monitoring aspects of the rule remained unchanged.)
June 8, 2001 (66 Fed. Reg. 31086)	USEPA adopted the filter backwash recycling rule, regulating the return of recycled flows to the filtration process that could potentially threaten the microbiologic integrity of the treatment process.

PUBLIC COMMENTS

The Board adopted a proposal for public comment in this matter on October 4, 2001. A Notice of Proposed Amendments appeared in the October 26, 2001 issue of the Illinois Register (at 25 Ill. Reg. 13382), beginning the 45-day public comment period. On December 20, 2001, at the December 5, 2001 request of USEPA, the Board extended the public comment period until January 9, 2002. At the same time, the Board set forth reasons for delay and extended the deadline for Board adoption of these amendments until February 22, 2002. A Notice of Public Information on Proposed Rules explaining the extension appeared in the January 4, 2002 issue of the Illinois Register (at 26 Ill. Reg. 247)

During the public comment period, the Board received four comments. Those comments are listed as follows:

PC 1	Lou Allyn Byus, Assistant Manager—Field Operations, Division of Public Water Supplies, Illinois Environmental Protection Agency (dated October 19, 2002)

PC 2	Lou Allyn Byus, Assistant Manager—Field Operations, Division of Public Water Supplies, Illinois Environmental Protection Agency (dated November 1, 2002)

PC 3	Rita Garner, Ground Water and Drinking Water Branch, USEPA Region V (dated January 9, 2002)

PC 4	Stephen C. Ewart, Deputy Counsel, Division of Legal Counsel, Illinois Environmental Protection Agency (dated February 4, 2002)

In PC 1, the Agency requested that the Board withdraw the amendments based on the federal January 26, 2001 arsenic rule. The Agency essentially stated that the Board should delay action to adopt the amendments because USEPA action to implement the arsenic rule appeared uncertain. In PC 2, however, the Agency withdrew its request for delay in PC 1 because USEPA had announced its intent to implement the arsenic rule without further delay.

In PC 3, USEPA stated that it reviewed the proposed amendments. USEPA suggested a number of corrections that the Board has made in adopting the amendments. In PC 4, the Agency has also suggested a number of corrections to the amendments.

In addition to the public comments, the Board received documents from JCAR that suggested a number of corrections. The Board has revised segments of the amendments in response to the comments received, as appropriate. The table that begins at page 62 of this opinion briefly describes the revisions made since the October 26, 2001 proposal for public comment. The table that begins on page 78 outlines the suggested revisions that the Board has not made.

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 notices involved. Finally, this discussion closes with a description of the amendments and actions that are not directly derived from the federal actions.

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, 2000 version. Thus, we have updated all citations to the 2000 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. We 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, since it is not used in everyday language. Thus, where a federal rule uses “shall,” the Board substitutes “must.” 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. “Or” is used rather than “and/or,” and denotes “one or both.” “Either . . . or” denotes “one but not both.” “And” denotes “both.”

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.” We will continue this conversion in future rulemakings, as additional sections become open to amendment. We 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 13 of this opinion. There is no further discussion of most of the deviations and revisions elsewhere in this opinion.

Discussion of the Federal Actions

Amendments to the Interim Enhanced Surface Water Treatment Rule and the Stage 1 Disinfectants and Disinfection Byproducts Rule-Subparts I and R and Sections 611.232, 611.250, 611.310, 611.312, 611.313, 611.680, and 611.685

On January 16, 2001 (66 Fed. Reg. 3770), USEPA adopted minor amendments to the December 16, 1998 interim enhanced surface water rule (63 Fed. Reg. 69478) and the Stage 1 disinfectant residual and disinfection byproducts (DR/DBP) rule (63 Fed. Reg. 69390). On February 12, 2001 (66 Fed. Reg. 9903), USEPA corrected the January 16, 2001 amendments. USEPA had earlier adopted these amendments by a direct final rule on April 14, 2000 (65 Fed. Reg. 20304), but later withdrew those amendments as a result of adverse public comment on June 13, 2000 (65 Fed. Reg. 37052). USEPA ultimately again adopted the amendments on January 16, 2001 after receiving additional public comments.

The Board incorporated the federal amendments into the Illinois drinking water regulations in SDWA Update, USEPA Regulations (July 1, 1998 through December 31, 1998), R99-12 (July 22, 1999), based on an advanced copy of the amendments obtained from the USEPA. At that time the Board chose to proceed without delay to adopt the amendments because they altered the effective dates of the rules that they affected. The amendments ultimately adopted by USEPA on January 16, 2001, have only minimally changed the text of the federal amendments as submitted to the Board in a draft form in 1999. In this present action the Board effects those minimal changes to complete the federal amendments.

The Board has completed the January 16, 2001 federal amendments with only minimal deviation from the text of the federal amendments. Persons interested in a detailed explanation of the substance of the underlying federal action should refer to the notice that appeared in the January 16, 2001 issue of the Federal Register. Table 1, which begins on page 13 of this opinion, outlines the deviations from the literal text of the federal rules that the Board found necessary to incorporate the amendments. The Board will offer no explanation of most of those deviations beyond that set forth in the table, since none of the deviations are significant enough to warrant specific discussion.

The Board requested public comment on our incorporation of the January 16, 2001 federal amendments to the interim enhanced surface water rule and the Stage 1 DR/DBP rule into the Illinois drinking water regulations. The Board received comments from USEPA and incorporated a small number of revisions to the text of the amendments as a result. Those revisions are itemized in the table that begins on page 62 of this opinion.

National Primary Drinking Water Regulation for Arsenic-Subpart N and 611.101, 611.130, 611.300, 611.301, 611.646, 611.648, 611.884, 611.Appendix A, and Appendix G

On January 22, 2001 (66 Fed. Reg. 6976), USEPA adopted National Primary Drinking Water Regulations (NPDWRs) applicable to arsenic in drinking water. The arsenic rule will lower the MCL for arsenic from the current 0.05 mg/L to 0.01 mg/L, and it will revise the analytical methods used to determine compliance, amend the monitoring requirements, and change the public notification requirements that apply to arsenic. USEPA further adopted amendments to the new source compliance demonstration requirements applicable to all inorganic contaminants (IOCs), volatile organic contaminants (VOCs), and synthetic organic contaminants (SOCs). As initially adopted by USEPA, the federal arsenic rule contained a number of different effective dates and compliance dates. The effective date for these amendments was March 23, 2001, except that the monitoring and compliance requirements of the rule were to be effective January 22, 2004, and the compliance deadline for the arsenic MCL was January 23, 2006.

On March 23, 2001 (66 Fed. Reg. 16134), USEPA delayed the effective date of various aspects of the arsenic NPDWRs until May 22, 2001. On May 22, 2001 (66 Fed. Reg. 28342), USEPA again delayed various of the effective dates until February 22, 2002. Unaffected by these actions were the effective dates of the January 22, 2001 amendments pertaining to IOCs generally and to VOCs and SOCs. The effect of the March 23, 2001 and May 22, 2001 amendments was to shift the dates when the arsenic rule takes effect. The first action changed the effective date of the arsenic rule from March 23, 2001 to May 22, 2001. The second action shifted the effective date to February 22, 2002. USEPA stated in changing these dates, it was delaying the effective dates of the amendments “to reassess the scientific and cost issues associated with the arsenic rule . . ..” 66 Fed. Reg. 28342 (May 22, 2001). USEPA stated that the delayed effective dates did not affect the ultimate deadline for compliance with the new MCL for arsenic.

The following tables illustrate the initial and amended effective dates for the various aspects of the arsenic rule and the concurrent amendments:

The Board has incorporated the federal arsenic rule amendments into the Illinois drinking water regulations with minimal deviation from the literal text of the federal amendments. Persons interested in the substance of the underlying federal action should refer to the notice that appeared in the January 22, 2001, March 23, 2001, and May 22, 2001 issues of the Federal Register. Table 1, which begins on page 14 of this opinion, outlines the deviations from the literal text of the federal rules that the Board found necessary to incorporate the amendments. The Board will offer no explanation of most of those deviations beyond that set forth in the table. We do, however, explain the more significant deviations in this discussion.

One set of deviations from the federal text that the Board has found necessary relates to the various federal effective dates involved. We have found it necessary to preface several provisions with their federal effective dates. As explained in SDWA Update, USEPA Regulations (July 1, 2000 through December 31, 2000), R01-20 (Oct. 4, 2001), under federal law, USEPA can codify two versions of a single provision, with one effective up to a certain date and another effective after that date. The Board must codify those versions as separate provisions, and we can then later amend the regulations to remove the expired provision. The Board will codify the new provision under the existing subsection designation as effective on some future date, then renumber the existing provision under a new subsection designation as effective until that future date. Thus, the Board has prefaced Sections 611.601(d)(2), 611.603 preamble, 611.606(a), 611.609(a) and (b), as effective on February 22, 2002; Sections 611.611(b), (c), (o), and (o)(1) through (o)(6), and 611.648(k) and (k)(1) through (k)(5) as effective January 22, 2004 and Sections 611.646(o)(6) and (o)(7) and 611.648(k)(6) and (k)(7) as effective until January 22, 2004, the old MCL listed at Section 611.Appendix A (“arsenic”) as effective until January 23, 2006 and the new MCL as effective on January 23, 2006, and Section 611.300(b) as effective until January 23, 2006.

The Board makes a specific observation on one aspect of the effect of the federal arsenic rule on the Illinois regulations. Most segments of Section 611.300, as it exists today, are derived from the Illinois regulations adopted under Section 27 of the Act (415 ILCS 5/27 (2000)) that predate the federally derived SDWA regulations adopted as identical-in-substance rules under Sections 7.2 and 17.5 of the Act (415 ILCS 5/7.2 and 17.5 (2000)) and currently codified as 35 Ill. Adm. Code 611 today. See Safe Drinking Water Act Regulations, R88-26 (Aug. 9, 1990) at pp. 73-74; 35 Ill. Adm. Code 604.202 (1988). Over time, the federally-derived MCLs have been removed from this Section, leaving only the state-only inorganic MCLs but those for iron, manganese, and zinc. ¹ The January 23, 2006 expiration of the old arsenic MCL will remove that last federally derived rule from Section 611.300. After that date, the remaining provisions in this Section will be exclusively state-derived rules.

The Board requested public comment on our incorporation of the January 16, 2001 federal amendments to the radiologic contaminant rules into the Illinois drinking water regulations. The Board received comments from USEPA and incorporated a small number of revisions to the text of the amendments as a result. Those revisions are itemized in the table that begins on page 62 of this opinion.

Filter Backwash Rule-Sections 611.276 and 611.Appendices A and G

On June 8, 2001 (66 Fed. Reg. 31086), USEPA adopted the filter backwash recycling rule (FBRR). USEPA stated that the purpose of the FBRR is to protect public health by requiring suppliers to change their practice of return of filter backwash water to the treatment process; the purpose of the change is to avoid any compromise of microbial control. The FBRR addresses filter backwash water, sludge thickener supernatant water, and waters from dewatering processes. The FBRR added new 40 C.F.R. 141.76 to the regulations, which requires suppliers to submit a detailed written notification to the State by December 8, 2003, if it recycles spent filter backwash water, thickener supernatant, or dewatering process liquids. Suppliers are prohibited, effective June 8, 2004, against returning these flows to the treatment process except through the existing filtration system or to an alternative location approved by the State. The new rule requires that a supplier must complete all capital improvements necessary to comply with the rule’s requirements before June 8, 2006. Also effective June 8, 2004, the suppliers are required to maintain records containing specified information for State inspection.

The Board has incorporated the federal amendments into the Illinois drinking water regulations as 35 Ill. Adm. Code 611.276 with minimal deviation from the literal text of corresponding 40 C.F.R. 141.76. Persons interested in the substance of the underlying federal action should refer to the notice that appeared in the June 8, 2001 issue of the Federal Register. Table 1, which begins on page 13 of this opinion, outlines the deviations from the literal text of the federal rules that the Board found necessary to incorporate the amendments. The Board will offer no explanation of those deviations beyond that set forth in the table. We do, however, consider in this discussion specific significant issues raised by subsection (c) of the new Section.

The first issue relating to subsection (c) relates to State designation of alternative locations to return the backwash flows. The information required of the supplier for submission to the State is detailed engineering information that would help the State to gauge the performance and effectiveness of the supplier’s filtration process. No segment of the rule, however, sets forth an objective standard for performance or otherwise sets forth a basis for a State determination of an alternative location for introducing the flows. For this reason, and since the only basis for an Agency determination under the Act is by a permit issued pursuant to Section 39 of the Act (415 ILCS 5/39 (2000)), the Board has specified that an Agency determination of an alternative location for reintroducing return flows is to be made as a permit decision. Since standards for Agency permit issuance are set forth in Section 39 of the Act, with an Agency permit decision being subject to Board review under Section 40 of the Act (415 ILCS 5/39, 40 (2000)).

The second issue relating to subsection (c) of the new provision appears to require compliance with a plan approved by the State by June 8, 2004, but it also provides that the supplier must comply by no later than June 8, 2006 if capital improvements are necessary to achieve compliance. The question arises as to what must occur by June 8, 2004: must the State approve the point for reintroduction of the return flows, or must the supplier comply by returning those flows only to that point by that date? The Board reads this provision as requiring compliance by reintroducing the return flows only at an Agency-approved point in the process by that date. The second question that arises is whether the need for capital improvements to achieve compliance automatically extends the date for compliance until June 8, 2006, or if the mention of the extended compliance date is an indication that the State can extend the date in a specific case where proof has been made that capital improvements are required. The Board notes that section 1412(b)(10) of the federal SDWA (42 U.S.C. § 300g-1(b)(10) (1994)) allows the State to extend the deadline for compliance for up to two years where it determines that such an extension is necessary because the supplier needs to undertake capital improvements to achieve compliance. We read the extension provision of 40 C.F.R. 141.76(c) as referring to a two-year extension as allowed under section 1412(b) of SDWA, and not as automatically allowing such an extension. Thus, in order to obtain an extension of the compliance deadline, the supplier must file an appropriate petition under Section 28.1 or 37 of the Act (415 ILCS 5/28.1 or 37 (2000)) before the Board for relief from the June 8, 2004 date.

The Board requested public comment on our incorporation of the January 16, 2001 federal amendments to the filter backwash rule into the Illinois drinking water regulations. In particular, we requested specific comment on our interpretations concerning standards for State determination of the appropriate alternative location for reintroduction of return flows to the treatment process and to the availability of a two-year extension of the compliance deadline where capital improvements are necessary to achieve compliance. The Board received no comments on this aspect of the October 4, 2001 proposal for public comment.

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 (“waiving”) a Board regulation. It generally takes some form of Board action to “waive” 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.

Requested Revisions to the Text of the Proposed Amendments Not Made in Final Adoption

Section Affected	Source(s) of Request: Requested Revision(s)	Explanation
Amendments generally	JCAR: Why has the Board changed “system” to “supplier” throughout the rules?	In the initial adoption of the SDWA-derived rules on August 9, 1990, R88-26, at 14 Ill. Reg. 16517, effective September 20, 1990, the Board chose to use “supply” because the Act uses “public water supply” (415 ILCS 5/3.28 (2000)) in place of “public water system” in the federal statute (42 U.S.C. 300f(4) (1996)). The Board reads “supplier” as more clearly referring to a person, while “system” can mean the physical facilities used to treat and deliver water.
611.101	JCAR: Why did the Board remove the several notes stating “derived from 40 CFR 141.2?	Over the years, the Board has occasionally added definitions not directly derived from the corresponding federal compilation of definitions, where the addition of those definitions aids in understanding the regulations. While Section 611.101 is “derived” from 40 C.F.R. 141.2, a fact now noted in the end Board note, it does not precisely parallel that provision. Where definitions derive from federal provisions other than 40 C.F.R. 141.2, the Board has indicated that fact with a Board not attached to the particular definition. The Board has not particularly noted the definitions that the Board has added for the sake of clarity, since such addition would add little or nothing to the rules.
611.130(c)(2)	JCAR: Change “a SDWA” to “an SDWA”	The use of “a” is appropriate because the acronym is generally pronounced as “sid-wa.”
611.381(d)(4)	JCAR: What does “m-1” mean?	The variable “m^-1” derives directly from the corresponding federal text. It means reciprocal meters. When the energy absorbed by a unit volume of substance (measured as erg/m³) is factored against the radiant energy incident on a unit area of that substance (measured as erg/m²), the result is measured in reciprocal meters (m^-1).
611.382(b)(1)(A) table	JCAR: Shorten the table by using the full width of the page.	1 Ill. Adm. Code 100.390 requires that the Board indent the table text to the appropriate level for the third subsection level (three inches from the left margin.
611.382(b)(1)(B) table	JCAR: Shorten the table by using the full width of the page.	1 Ill. Adm. Code 100.390 requires that the Board indent the table text to the appropriate level for the third subsection level (three inches from the left margin.
611.384(b) note 1	JCAR: Change “exceeded” to “violated”	The language appears as it does in the text of the federal original; changing the language could change the meaning.
611.383 Board note	JCAR: Change the indent level of the note to that of a subsection.	1 Ill. Adm. Code 100.390 requires that the Board note appear at the indent level of the text to which it refers, and this note relates to the entire Section.
611.384(c)(2)(C)	JCAR: Change “exceeded” to “violated”	The language appears as it does in the text of the federal original; changing the language could change the meaning.
611.384(c) note 1	JCAR: Change “exceeded” to “violated”	The language appears as it does in the text of the federal original; changing the language could change the meaning.
611.385(a)(2)(E)	JCAR: What does “L/mg-m” mean?	“L/mg-m” means liters per milligram-meter. This derives directly from the corresponding federal text. In determining the SUVA, absorption (measured as m^-1) is divided by the DOC (measured as mg/L). The resulting units are liters per milligram-meter (L/mg-m).
611.385(a)(2)(F)	JCAR: What does “L/mg-m” mean?	See the preceding entry for Section 611.385(a)(2)(E).
611.385(b)(2)	JCAR: Why is “source-water” hyphenated?	The term “source-water” derives directly from the corresponding federal text. It is a compound for which hyphenation is appropriate.
611.385(c)(2)(C)	JCAR: What does “L/mg-m” mean?	See the preceding entry for Section 611.385(a)(2)(E).
611.385(c)(2)(D)	JCAR: What does “L/mg-m” mean?	See the preceding entry for Section 611.385(a)(2)(E).
611.611(a)(20)(A)(i)	JCAR: Add a comma after “Method.”	The reference to “ASTM Method D511-93 A” already appears in the standardized format for this type of reference.
611.646(k)	JCAR: Change the semicolons to commas to separate the elements of the series.	Semicolons are appropriate because one element contains a parenthetical offset by a comma.
611.646(k)(2)	JCAR: Add “must be required” to “is required”.	“Annual monitoring” acts as a subsection heading, so the addition is not necessary. Further, the addition to a provision that also allows a reduction in monitoring frequency could cause confusion.
611.Appendix A, “haloacetic acids”	JCAR: What is the difference between “HAAs” and HAA5”?	The abbreviations “HAA5” and “HAA” derive directly from corresponding segments of the federal text. “HAA” means “haloacetic acids” generally, and the Board has rendered the abbreviation as “HAAs” because it represents a plural. USEPA also used “HAAs.” “HAA5” also denotes haloacetic acids, but more specifically refers to the five principal haloacetic acids: monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid.
611.Appendix G, mandatory health effects language generally	JCAR: What is the difference between “over a long period of time” and “over many years”?	The Board is unaware of the difference between “over a long period of time” and “over many years.” The Board cannot explain why USEPA chose one phrase over the other when developing the mandatory health effects language for the various contaminants, however, the Board is compelled by statute to incorporate the federal language into the Illinois regulations. The Board has incorporated the federal language into the Illinois regulations without substantive review, as required.
611.Appendix G, ¶ I.G.	JCAR: What is the difference between “HAAs” and HAA5”?	See the preceding entry for Section 611.Appendix A, “haloacetic acids”
611.Appendix G, ¶ III	JCAR: Change “a SDWA” to “an SDWA.”	The use of “a” is appropriate because the acronym is generally pronounced as “sid-wa.”
611.Appendix G, note 18	JCAR: Capitalize “sections.”	JCAR has elsewhere requested that the Board use lower-case “sections” when referring to federal provisions. (See, e.g., the JCAR-requested revisions to Sections 611.130(g)(5), (g)(6), and (g)(7).)
611.Appendix G, note 19	JCAR: Change “a SDWA” to “an SDWA.”	The use of “a” is appropriate because the acronym is generally pronounced as “sid-wa.”
611.Appendix G, note 19	JCAR: Add a date to the reference to “40 CFR 142.307”	No date is necessary, since this note does not incorporate any requirements of 40 C.F.R. 142.307 and the actual version of that regulation is immaterial to the function of this footnote of informing the regulated community of another federal requirement.
611.Appendix H, ¶ 24	JCAR: “‘Personal doctor’ as opposed to the ‘company doctor’?”	“Personal doctor” is mandatory federal language derived directly from the corresponding federal requirement. The Board will not change it.
611.Appendix H ¶ 28	JCAR: Add the word “experience” after “or.”	“Or reproductive difficulties” is mandatory federal language derived directly from the corresponding federal requirement, and the federal language is clear without revision. The Board will not change it.
611.Appendix H ¶ 32	JCAR: “Their kidneys could improve?”	“Minor kidney changes” is mandatory federal language derived directly from the corresponding federal requirement, and the federal language is clear without revision. We will not change it.
611.Appendix H ¶ 33	JCAR: Add the word “experience” after “or.”	“Or reproductive difficulties” is mandatory federal language derived directly from the corresponding federal requirement, and the federal language is clear without revision. The Board will not change it.
611.Appendix H, ¶ 87	JCAR: What is the difference between “HAAs” and HAA5”?	See the preceding entry for Section 611.Appendix A, “haloacetic acids”

I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, certify that the Board adopted the above opinion on February 21, 2002, by a vote of 7-0.
