Proposed Rule. Proposal for Public Comment.

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

Under Sections 7.2 and 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and 17.5 (1998)), the Board proposes amendments to the Illinois regulations that are “identical in substance” to drinking water regulations that the United States Environmental Protection Agency (USEPA) adopted to implement Sections 1412(b), 1414(c), 1417(a), and 1445(a) of the federal Safe Drinking Water Act (SDWA) (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and 300j-4(a) (1998)). The nominal timeframe of this docket includes federal SDWA amendments that USEPA adopted in the period January 1, 2000, through June 30, 2000.

Sections 7.2 and 17.5 provide for quick adoption of regulations that are identical in substance to federal regulations that USEPA adopts to implement Sections 1412(b), 1414(c), 1417(a), and 1445(a) of the federal Safe Drinking Water Act (SDWA) (42 U.S.C. §§ 300g-1(a), 300g-3(c), 300g-6(a), and 300j-4(a) (1998)). Section 17.5 also provides that Title VII of the Act and Section 5 of the Administrative Procedure Act (APA) (5 ILCS 100/5-35 and 5-40 (1998)) do not apply to the Board’s adoption of identical-in-substance regulations. The federal SDWA regulations are found at 40 C.F.R. 141 through 143.

This opinion supports an order that the Board also adopts today. The Board will cause the proposed amendments to be published in the Illinois Register and will hold the docket open to receive public comments for 45 days after the date of publication.

FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING

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

Docket R01-7: January 1, 2000, through June 30, 2000, SDWA Amendments

USEPA amended the federal SDWA regulations on eight occasions during the period January 1, 2000, through June 30, 2000. Each is summarized below:

65 Fed. Reg. 1950 (January 12, 2000)

USEPA made a number of minor amendments to the lead and copper rule in order to facilitate implementation of the rule.

65 Fed. Reg. 11372 (March 2, 2000)

USEPA amended its September 17, 1999 (64 Fed. Reg. 50556) unregulated contaminants monitoring rule.

65 Fed. Reg. 20304 (April 14, 2000)

USEPA adopted amendments to the December 16, 1998 interim enhanced surface water treatment rule (64 Fed. Reg. 69478) and the Stage 1 disinfectants and disinfectant byproducts rule (64 Fed. Reg. 69390).

65 Fed. Reg. 25982 (May 4, 2000)

USEPA adopted amendments to the public notification rules, which prescribe the form, manner, content, and frequency of public notice under the drinking water rules. The amendments implement the community-right-to-know provisions of the SDWA Amendments of 1996.

65 Fed. Reg. 34404 (May 30, 2000)

USEPA removed the maximum contaminant level goal (MCLG) of zero for chloroform in drinking water. This was in response to the vacatur in Chlorine Chemistry Council and Chemical Manufacturers Association v. EPA, slip op., No. 98-1627 (D.D.C. March 31, 2000).

65 Fed. Reg. 37052 (June 13, 2000)

USEPA withdrew its April 14, 2000 direct final rule relating to the interim enhanced surface water treatment rule and the Stage 1 disinfectants and disinfectant byproducts rule in response to adverse public comments.

65 Fed. Reg. 38629 (June 21, 2000)

USEPA corrected its May 4, 2000 public notification rule.

65 Fed. Reg. 40520 (June 30, 2000)

USEPA corrected its May 4, 2000 public notification rule.

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, 2000, 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. If the Board identifies any federal actions that fulfill these criteria prior to final action on the present amendments, it may include those amendments in the present update docket R01-7.

SDWA (Drinking Water) Amendments on Which No Board Action Will Be Necessary

Among the various federal SDWA amendments examined by the Board and listed above, there are some on which no Board action will be necessary in the present update docket R01-7. The reasons why no Board action will be necessary vary from one federal action to another. The Board lists these four federal actions among those considered in this docket for the benefit of the regulated community, but we do not further discuss them in this opinion.

1.	No Board action will be necessary on the federal action of March 2, 2000 (65 Fed. Reg. 11372). The federal action amended the September 17, 1999 (64 Fed. Reg. 50556) unregulated contaminants monitoring rule. In the prior update docket SDWA Update, USEPA Amendments (July 1, 1999, through December 31, 1999) (July 22, 2000), R00-12, the Board determined that it was not necessary to incorporate the unregulated contaminants monitoring rule into the Illinois drinking water regulations.

2.	Similarly, no Board action will be necessary on the federal action of April 14, 2000 (65 Fed. Reg. 20304). These amendments to the December 16, 1998 interim enhanced surface water treatment rule (64 Fed. Reg. 69478) and the Stage 1 disinfectants and disinfectant byproducts rule (64 Fed. Reg. 69390) were a direct final rule. On June 13, 2000 (65 Fed. Reg. 37052; see below), USEPA withdrew these amendments in response to adverse public comments.

3.	No action will be necessary as to the federal cleanup amendments of May 30, 2000 (65 Fed. Reg. 34404). The USEPA removal of the MCLG for chloroform in response to the decision in Chlorine Chemistry Council and Chemical Manufacturers Association v. EPA, slip op., No. 98-1627 (D.D.C. March 31, 2000), did not affect any rule with a counterpart in the Illinois regulations. The MCLGs are outside the Board’s SDWA identical-in-substance mandate, so no Board actions will be needed to incorporate these amendments into the Illinois rules.

4.	The federal action of June 13, 2000 (65 Fed. Reg. 37052), was the withdrawal of the amendments of April 14, 2000 (65 Fed. Reg. 20304; see above) to the interim enhanced surface water treatment rule and the Stage 1 disinfectants and disinfectant byproducts rule.

Summary Listing of the Federal Actions Forming the Basis of the Board’s Actions in this Docket

Based on the foregoing, the federal actions that form the basis for Board action in this update docket are as follows, in chronological order:

65 Fed. Reg. 1950 (January 12, 2000)	Amendments to the lead and copper rule intended to facilitate implementation.
65 Fed. Reg. 25982 (May 4, 2000)	Amendments to the public notification rules intended to implement the community-right-to-know provisions.
65 Fed. Reg. 38629 (June 21, 2000)	Corrections to the May 4, 2000 public notification rule.
65 Fed. Reg. 40520 (June 30, 2000)	Corrections to the May 4, 2000 public notification rule.

PUBLIC COMMENTS

The Board will receive public comments on this proposal for a period of 45 days following its publication in the Illinois Register. After that time, the Board will immediately consider adoption of the amendments, making any necessary changes made evident through the public comments. The Board will file any adopted rules with the Secretary of State immediately after adoption.

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, 1999 version. Thus, we have updated all citations to the 1999 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.”

The Joint Committee on Administrative Rules (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, 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. There is no further discussion of most of the deviations and revisions elsewhere in this opinion.

Discussion of Particular Federal Actions

Lead and Copper Amendments—Sections 611.126 and Subpart G

On January 12, 2000 (65 Fed. Reg. 1950), USEPA adopted amendments to the June 7, 1991 (56 Fed. Reg. 26460) lead and copper rule. The Board adopted the lead and copper rule in Safe Drinking Water Act Update, Phase IIB and Lead and Copper Rules (June 1, 1991, through December 31, 1991) (May 5, 1993), R92-3. USEPA adopted a number of corrections to the lead and copper rule on June 30, 1994 (59 Fed. Reg. 33860) , which the Board subsequently incorporated into the Illinois regulations in Safe Drinking Water Act Update, Lead and Copper Rules Corrections (January 1 through June 30, 1994) Safe Drinking Water Act Update, Phase II, IIB & V Corrections & Analytical Methods Amendments (July 1 through December 31, 1994) (June 15, 1995), R94-23/R95-3 (consolidated). USEPA stated that the January 12, 2000 corrections are intended to eliminate unnecessary provisions, streamline and reduce the reporting requirements, and facilitate consistent implementation of the rule. USEPA stated that the amendments do not affect the lead and copper action levels or the basic regulatory requirements.

The Board has incorporated the federal amendments into the Illinois drinking water regulations with minimal deviation from the literal text of the federal amendments. In the course of incorporating the federal amendments into the Illinois rules, the Board has found it necessary to undertake some minor deviations due to problems with the literal text of the federal rules. Persons interested in the substance of the underlying federal action should refer to the notice that appeared in the January 19, 2000 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. We do, however, explain a couple of the more significant deviations in this discussion.

One deviation relates to the federal definition of “lead free.” The federal rules, at 40 C.F.R. 141.86(g)(1)(i)(B) (corresponding with 35 Ill. Adm. Code 611.356(g)(1)(A)(ii)), define “lead free” as it relates to plumbing fixtures and fittings. The federal rules define as “lead free” those fixtures and fittings that “meet the specifications of any standard established pursuant to 42 U.S.C. 300g-6(e) (SDWA section 1417(e)).” Section 1417(e) mandates that USEPA provide information to “qualified third-party certifiers in the development of standards and testing protocols” for the fixtures and fittings. The Board cannot incorporate such an open-ended definition into the Illinois Administrative Code. Rather, under Section 5-75 of the Illinois Administrative Procedure Act, the Board must reference a particular standard and a particular version of that standard. (415 ILCS 100/5-75 (1998).)

In the earlier update docket, SDWA Update, USEPA Regulations (January 1, 1998, through June 30, 1998) (February 4, 1999), R99-6, the Board amended 35 Ill. Adm. Code 611.126(d) (corresponding with 40 C.F.R. 141.43(d)) to correspond with required federal amendments to Section 1417(d) of SDWA (42 U.S.C. 300g-6(d) (1998)) relating to the definition of “lead free” fixtures and fittings. Those federal amendments also defined “lead free” in t erms of standards adopted under Section 1417(e) of SDWA (42 U.S.C. 300g-6(e) (1998)). The Board noted that USEPA had asserted in the Federal Register, at 62 Fed. Reg. 44684 (August 22, 1997) that National Sanitation Foundation (NSF) Standard 61, Section 9 was a standard adopted under Section 1417(e) of SDWA, and we incorporated the NSF standard by reference in place of the impermissible “any standard” language.

Confronting this same USEPA open-ended incorporation of “any standard” into the federal rules, the Board resolves the issues that it raises by the same means that we used in SDWA Update, USEPA Regulations (January 1, 1998, through June 30, 1998) (February 4, 1999), R99-6. We substitute a reference to NSF Standard 61 in 35 Ill. Adm. Code 611.356(g)(1)(A)(ii) for the federal reference to “any standard” at corresponding 141.86(g)(1)(i)(B). The Board added a Board note at Section 611.356(g)(1)(A)(ii) for the convenience of the regulated community that briefly states the corresponding federal “any standard” language and explains the substitution. We also revisited the definition of “lead free” at Section 611.126 and added parallel explanatory language at that location. The Board has no other alternatives for incorporating the substance of the federal rules and drafting amendments that are no less stringent than the federal rules in fulfillment of our mandate under Sections 7.2 and 17.5 of the Act (415 ILCS 5/7.2 and 17.5 (1998)).

Another series of issues raised by the amendments to the federal lead and copper rule relate to flexibility that USEPA has instilled in various segments of the rules. In various segments of the federal rules, USEPA provides that the State can either tighten or relax the general requirements. Examples of such provisions are summarily tabulated as follows:

Federal Provision	State Provision	General Subject
40 C.F.R. 141.84(d)(1)(ii)	Section 611.354(d)(1)(B)	Providing less than 45 day notice of lead service line replacement
40 C.F.R. 141.84(d)(2)	Section 611.354(d)(2)	Providing notice by an alternative means
40 C.F.R. 141.85(a)(1) & (a)(2)	Section 611.354(a)(1) & (a)(2)	Omission of lead service line information from notice
40 C.F.R. 141.86(b)(5)(i) & (b)(5)(iii)	Section 611.356(b)(5)(A) & (b)(5)(C)	Substitute first-draw samples
40 C.F.R. 141.86(c)(2)	Section 611.356(c)(2)	Sampling location for reduced monitoring
40 C.F.R. 141.86(d)(4)(ii)-(d)(4)(iv)	Section 611.356(d)(4)(B)-(d)(4)(D)	Reduced monitoring
40 C.F.R. 141.86(d)(4)(vi) & (d)(4)(vii)	Section 611.356(d)(4)(F) & (d)(4)(G)	Return to standard monitoring
40 C.F.R. 141.86(g)(3)	Section 611.356(g)(3)	Reduced monitoring
40 C.F.R. 141.88(a)(1)(iv)	Section 611.358(a)(1)(D)	Composite sampling
40 C.F.R. 141.88(e)(1)(ii) & (e)(2)(ii)	Section 611.358(e)(1)(B) & (e)(2)(B)	Reduced monitoring
40 C.F.R. 141.90(e)(4)	Section 611.360(e)(4)	Reduced reporting frequency
40 C.F.R. 141.90(f)(2)	Section 611.360(f)(2)	Waiver of reporting due to prior submission

In each instance of such regulatory flexibility built into the federal regulations, the Board has used the mechanism of the special exemption permit (SEP) under Section 611.110 to allow the Agency to permit (or deny) the grant of flexibility or imposition of a more restrictive requirement. After examination of each instance of this use of the SEP, the Board believes that the regulatory context provides sufficient standards for an Agency decision and for Board review of any Agency decision.

Other issues were raised by certain dates incorporated by USEPA into its rules. In various segments of the rules, USEPA imposes requirements based on dates that are already past. These dates appear at each of the following segments of the federal rules: 40 C.F.R. 141.81(b)(3)(ii), 141.84(a)(1), 141.86(g)(7) and (g)(7)(B), and 141.90(a)(2)(i) and (a)(4). Where federal rules set forth past dates that could be read as past-effective dates, the Board generally omits them. The problem with the dates in the current federal amendments is that these dates dictate the current or future applicability of segments of the rules. Thus, it is likely that omission of the dates could impermissibly render the Illinois regulations less stringent than the corresponding federal rules. For this reason, the Board left the past dates in corresponding Sections 611.351(b)(3)(B), 611.354(a)(1), 611.356(g)(7) and (g)(7)(B), and 611.360(a)(2)(A) and (a)(4). At each subsection of the Illinois rules, we inserted a Board note that explains the retention of the past date from the federal rules.

The final three deviations from the text of the federal amendments that are warranting specific note relate to non-substantive aspects of the federal rules that the Board has retained for the purposes of parity with the federal rules and to fully inform the regulated public. At Section 611.352(g)(1), the Board retained language from corresponding 40 C.F.R. 141.52(g)(1) relating to federal approval of an alternative State formula for calculation. We perceive this language as non-substantive because it has no direct impact on the regulated community, so the Board added a brief introductory statement and inserted the federal language into a Board note. Similarly, 40 C.F.R. 141.90(a)(3) encourages prior notification to the State, but does not require it. The Board added introductory language at corresponding Section 611.60(a)(3) clearly stating that USEPA encourages the prior notice, but that it is not required. Finally, USEPA removed 40 C.F.R. 141.90(c)(1)(iii) and marked it as “reserved.” In order to maintain structural parity with the federal rules, the Board added a statement at corresponding Section 611.360(c)(1)(C) explaining the federal action and that we inserted a statement to maintain structural consistency between the State and federal rules. Without such consistency, locating parallel segments of text and maintaining the accuracy of cross-references within the text can become very difficult for the Board, USEPA, and the regulated community.

The Board requests public comment on our incorporation of the January 12, 2000 federal amendments to the lead and copper rule into the Illinois drinking water regulations. In particular, we request specific comment on our substitution of the NSF standard for the federal “any standard” language, the use of the SEP to implement regulatory flexibility, our retention of past dates in the regulatory text, and on the three non-substantive deviations from the federal text that are discussed in the above paragraph.

Amendments to the Public Notification Rules—Sections 611.261; 611.300; 611.606; 611.646; 611.648; 611.745; Subparts T, U, and V; and Appendices F, G, H, and I

On May 4, 2000 ( 65 Fed. Reg. 25982 ), USEPA amended its public notification rules to fulfill the requirements of the 1996 SDWA amendments. The public notification rules outline when and how a public water supply owner or operator must publish notice to the public of various occurrences. Public notice is required in the event of a violation of a National Primary Drinking Water Regulation (NPDWR), when the supplier obtains relief equivalent to a federal variance or exemption from a NPDWR, or in other instances that could pose a threat to human health. USEPA also revised the August 19, 1998 (63 Fed. Reg. 44511) consumer confidence report (CCR) rules. The Board originally adopted the CCR rules in SDWA Update, USEPA Regulations (July 1, 1998, through December 31, 1998) (July 22, 1999), R99-12. USEPA corrected its May 4, 2000 amendments on June 21, 2000 (65 Fed. Reg. 38629) and June 30, 2000 (65 Fed. Reg. 40520).

The Board has incorporated the May 4, 2000 federal amendments and June 21 and 30, 2000 corrections into the Illinois drinking water regulations with minimal deviation from the literal text of the federal amendments. In the course of incorporating the federal amendments into the Illinois rules, the Board has found it necessary to undertake some minor deviations due to problems with the literal text of the federal rules. Persons interested in the substance of the underlying federal action should refer to the notices that appeared in the May 4 and June 21 and 30, 2000 issues 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. On the other hand, some of the issues raised warrant specific discussion. Those discussions follow.

One significant issue raised by the federal notice amendments relates to the effective date. The amended applicability statement of the existing public notice rules at 40 C.F.R. 141.32 provides that the existing rules apply until the new requirements of 40 C.F.R. Subpart Q become effective. Amended 40 C.F.R. 141.32 and added 40 C.F.R. 141.201 state that Subpart Q is effective October 31, 2000 in states in which USEPA directly implements the SDWA program. In states, like Illinois, that are federally-authorized to implement the SDWA program (i.e., in authorized states), the new federal Subpart Q requirements go into effect on May 6, 2002, or on the date that the State adopts the requirements, whichever is earlier. This essentially means that the Board can determine the effective date for the new public notice rules; the Board may either allow the rules to become effective upon adoption (most likely in early January 2001) or provide for a delayed effective date (as late as May 6, 2002).

The Board has chosen to make the new public notice requirements become effective upon adoption, when they are filed with the Secretary of State. This has entailed the outright repeal of Sections 611.832, 611.851 through 611.856, and existing Appendix A to Part 611, which are derived from 40 C.F.R. 141.32, although Appendix A has been replaced with a new Appendix A based on a newly-added federal provision. The Board chose this approach because we perceive the new public notice requirements as affording a bit more flexibility to the Agency and the regulated community. If public comments indicate that this assessment is incorrect, and a delayed effective date is requested, the Board could adopt a final version of these amendments that uses a sunset provision in Sections 611.832, 611.851 through 611.856, and existing Appendix A to Part 611 and a delayed effective date in Section 611.901 (to correspond with that in 40 C.F.R. 141.201.

The federal regulations repeatedly refer to maximum contaminant level goals (MCLGs) and maximum residual disinfectant level goals (MRDLGs). These are the federally-derived goals for the maximum amount of a contaminant allowable in drinking water; they are not mandatory NPDWRs within the scope of the Board’s identical-in-substance mandate. Thus, the Board has not generally included segments of the federal rules that relate to MCLGs or MRDLGs. In these amendments, however, the Board has retained provisions relating to MCLGs and MRDLGs. At Section 611.883(c)(1)(A) and (c)(3)(C) (corresponding with 40 C.F.R. 141.153(c)(1)(i) and (c)(3)(iii)), the rules prescribe mandatory definition language for these terms for the purposes of public notice. At Appendices A, H, and I to Part 611 (corresponding with Appendix A to 40 C.F.R. 141, Subpart O and Appendices B and C to 40 C.F.R. 141, Subpart Q), the MCLGs and MRDLGs are set forth and defined, but in a way that makes them appear similarly integral to the public notice requirements. The Board is reluctant to incorporate any non-mandatory federal provisions into the Illinois rules, unless those federal provisions are indirectly necessary for maintaining federal authorization of the Illinois SDWA program. In this instance, these non-mandatory federal provisions appear necessary to fully incorporate the federal public notice requirements.

The new federal notice rules include references to variances and exemptions in several locations (at 40 C.F.R. 141.201(a)(2), 141.203(a)(3), 141.204(a)(3) and (b)(1), 141.205(b) and (d)(1), 141.206(a) and (b), and Appendix A to 40 C.F.R. 141, Subpart Q). Public notice is required when relief is granted from the NPDWRs. Section 1415 of SDWA (42 U.S.C. 300g-4) allows grants of “variances,” and Section 1416 (42 U.S.C. 300g-5) allows grants of “exemptions.” A federal “variance” is not directly equivalent to a variance granted by the Board pursuant to Sections 35 through 38 of the Act. Thus, the Board began to refer to relief from a NPDWR as “relief equivalent to a SDWA Section 1415 variance” (or “relief equivalent to a variance”) or “relief equivalent to a SDWA Section 1416 exemption” (or “relief equivalent to an exemption”) in SDWA Update, USEPA Regulations (July 1, 1998, through December 31, 1998) (July 22, 1999), R99-12. For this reason, the Board has added the “relief equivalent to” language in 35 Ill. Adm. Code 611.901(a)(2), 611.903(a)(3), 611.904(a)(3) and (b)(1), 611.905(b) and (d)(1), 611.906(a) and (b), and Appendix G to Part 611. An alternative might have been to substitute “variance, adjusted standard, or site-specific rule” for “variance or exemption” where it appears in the federal rules, but the Board believes that consistent usage within Part 611 is preferable, and Sections 611.111 and 611.112 adequately define what is “relief equivalent to” the relief provided by SDWA.

As with the federal lead and copper rule, USEPA has instilled regulatory flexibility in various segments of the public notice rules. In various segments of the federal rules, USEPA provides that the State can either tighten or relax the generally-applicable requirements. Examples of such provisions are summarily tabulated as follows:

Federal Provision	State Provision	General Subject
40 C.F.R. 141.201(a)(3)(v)	Section 611.901(a)(3)(E)	Requiring public notice in other situations where necessary
40 C.F.R. 141.201(c)(2)	Section 611.901(c)(2)	Allowing limited distribution of notice
40 C.F.R. 141.202(a)(8)	Section 611.902(a)(8)	Requiring public notice in other situations where necessary
40 C.F.R. 141.202(c)(4)	Section 611.902(c)(4)	Allowing use of alternative means of distribution
40 C.F.R. 141.203(a)(1) & (a)(2)	Section 611.903(a)(1) & (a)(2)	Requiring use of a different tier designation for notice
40 C.F.R. 141.203(b)(1)	Section 611.903(b)(1)	Allowing more time for notice
40 C.F.R. 141.203(c)(1) & (c)(2)	Section 611.903(c)(1) & (c)(2)	Allowing alternative method for notice
40 C.F.R. 141.204(a)(1) & (a)(2)	Section 611.904(a)(1) & (a)(2)	Requiring use of a different tier designation for notice
40 C.F.R. 141.204(c)(1)	Section 611.904(c)(1)	Allowing alternative method for notice
40 C.F.R. 141.205(c)(2)(i)	Section 611.905(c)(2)(A)	Requiring notice in a language other than English

In each instance of such regulatory flexibility built into the federal regulations, the Board has used the mechanism of the special exemption permit (SEP) under Section 611.110 to allow the Agency to permit (or deny) the grant of flexibility or the imposition of a more restrictive requirement. We believe that this regulatory flexibility is an element of the federal scheme that USEPA would require in the Illinois SDWA program. After examination of each instance of this use of the SEP, the Board believes that the regulatory context provides sufficient standards for an Agency decision and for Board review of any Agency decision.

A set of minor deviations from the text of the federal amendments warranting specific note are entirely non-substantive in nature. The Board has found it necessary to reformat Appendix 40 C.F.R. 141, Subpart O when incorporating it into Appendix A to Part 611. It is very difficult to incorporate appendices and tables into the Illinois Administrative Code that are presented in the “landscape” mode on the page. The federal table of Appendix A would have required this if kept in the table format. The Board has opted to present the information in the “portrait” mode on the page by reworking it into a paragraph format. The Board also found it necessary to codify the mandatory lead health effects information of 40 C.F.R. 141.85(a)(2) applicable to non-transient non-community water system suppliers (NTNCWSs) as Appendix F to Part 611, rather than as a segment of Section 611.355(a). This follows our having previously included the required health effects information for community water systems, from 40 C.F.R. 141.85(a)(1), as Appendix E in Safe Drinking Water Act Update, Lead and Copper Rules Corrections (January 1 through June 30, 1994) Safe Drinking Water Act Update, Phase II, IIB & V Corrections & Analytical Methods Amendments (July 1 through December 31, 1994) (June 15, 1995), R94-23/R95-3 (Consolidated).

The Board added a Board note to Appendix F explaining that the Illinois Department of Public Health (IDPH) is the entity that actually regulates NTNCWSs, but the IDPH incorporates the Board rules by reference for the purposes of its own standards. The Board routinely incorporates rules applicable to NTNCWSs for this purpose. USEPA removed 40 C.F.R. 141.24(h)(11) and marked it as “reserved.” As discussed above as to the USEPA removal of 40 C.F.R. 141.90(c)(1)(iii) as part of its lead and copper rule amendments, the Board added a statement at corresponding Section 611.648(k) explaining the federal action and that we inserted a statement to maintain structural consistency between the State and federal rules in order to maintain structural parity with the federal rules. As mentioned in the segment of this discussion relating to the lead and copper rule, this facilitates future use and maintenance of the Illinois rules.

The Board requests public comment on our incorporation of the May 4, 2000 federal public notice amendments and the June 21 and 30, 2000 corrections to those amendments. We specifically request comment on the aspects of the amendments included in this discussion: 1) the immediate repeal of the existing public notice rules and effectiveness of the new rules, rather than using a delayed date; 2) the inclusion of the aspects of the public notice rules that relate to MCLGs and MRDLGs; 3) the use of “relief equivalent to a variance or exemption” instead of converting the language to “a variance, an adjusted standard, or a site-specific rule”; 4) the use of the SEP as a mechanism for regulatory flexibility; 5) the restructuring of Appendix A; 6) the addition of Appendix F; 7) the addition of the Board note to Appendix F; and 8) the response to the removal of 40 C.F.R. 141.90(c)(1)(iii).

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.
