Proposed Rule. Proposal for Public Comment.

OPINION OF THE BOARD (by T.E. Johnson):

The Board today proposes 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) (2003)).

The R07-2 docket includes federal SDWA amendments that USEPA adopted in the

periods January 1, 2006 though June 30, 2006, and the R07-11 docket includes federal SDWA

amendments that USEPA adopted in the periods July 1, 2006 though December 31, 2006. The

amendments incorporate into the Illinois regulations three related, significant new federal rules:

the Stage 2 Disinfectants and Disinfection Byproducts Rule, the Long Term 2 Enhanced Surface

Water Treatment Rule, and the Groundwater Rule.

Sections 7.2 and 17.5 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 and

17.5 (2004)) 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 (2004)) 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 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. The Board will then adopt and file the final rules, taking into account the public

comments received. The Board presently expects that rules will be adopted and filed no later

than August 6, 2007, pursuant to the extension of the deadline adopted by the Board on April 19,

2007 pursuant to Section 7.2(b) of the Act (415 ILCS 5/7.2(b) (2004)).

This opinion supports an order that the Board also adopts today.

FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING

This docket includes federal SDWA amendments that USEPA adopted in two

consecutive time periods: January 1, 2006 though June 30, 2006 and July 1, 2006 though

December 31, 2006. USEPA adopted three sets of amendments during the two periods that

affected the SDWA primary drinking water regulations. The following briefly summarizes those

three principal federal actions that are considered in this rulemaking, including four corrections

to them:

January 4, 2006 (71 Fed. Reg. 388)

USEPA adopted the Stage 2 Disinfectants and Disinfection Byproducts Rule (DBPR).

The DBPR regulates drinking water disinfection practices and the content of disinfection

byproducts in drinking water. The Stage 2 DBPR is intended to further reduce the risks of

cancer and reproductive and other adverse health effects associated with disinfection byproducts.

The Stage 2 rule includes maximum contaminant level standards and monitoring, reporting, and

public notification requirements for these contaminants. The Stage 2 rule applies to any

community water supply or non-transient, non-community water system that adds a disinfectant

other than ultraviolet light to drinking water.

Implementation of the Stage 2 DBPR occurs in phases, and the deadlines for completion

of the various phases are staggered, depending on system size. The earliest compliance deadline,

that for a supplier that serves 100,000 persons or more to submit an initial distribution system

evaluation (IDSE) plan to the State, was October 1, 2006. The latest compliance deadline, which

requires compliance with the monitoring requirements by a supplier that serves fewer than

10,000 persons of which

Cryptosporidium

monitoring is required, is October 1, 2014.

The Stage 2 DBPR is an extension of the existing Stage 1 DBPR, adopted by USEPA on

December 16, 1998 (at 63 Fed. Reg. 69390) and by the Board on July 22, 1999 (in docket R99-

12). The DBPR is a companion to the Enhanced Surface Water Treatment Rule (see the entry

below for the January 5, 2006 USEPA action). The federal amendments include corrections to

existing regulations and to the existing Stage 1 DBPR.

January 5, 2006 (71 Fed. Reg. 654)

USEPA adopted the Long Term 2 Enhanced Surface Water Treatment Rule

(LT2ESWTR). The LT2ESWTR requires the use of treatment techniques and imposes

monitoring, reporting, and public notification requirements on all systems that use surface water

as a source of raw water. USEPA intends that the rule protect against

Cryptosporidium

and

other microbial contaminants, like

Giardia lamblia

.

---

3

Implementation of the LT2ESWTR occurs in phases, just as it does for the Stage 2

DBPR. The deadlines for completion of the various phases are staggered, also depending on

system size. The earliest compliance deadline, that for a supplier that serves 100,000 persons or

more to begin its first round of monitoring was October 1, 2006. The latest compliance deadline,

which requires a supplier that serves fewer than 10,000 persons which monitors for

Cryptosporidium

to begin a second round of monitoring, is April 1, 2019.

The LT2ESWTR is an extension of earlier rules pertaining to treatment of surface water

that USEPA has adopted. USEPA adopted the Surface Water Treatment Rule (SWTR) and the

Total Coliform Rule (TCR) on June 29, 1989 (at 54 Fed. Reg. 27486 and 27544, respectively),

and the Board adopted the rules on May 24, 1990 (in docket R88-26). USEPA then adopted the

Interim Enhanced Surface Water Treatment Rule (IESWTR) on December 16, 1998 (at 63 Fed.

Reg. 69478), which the Board adopted together with the Stage 1 DBPR (see the entry for the

USEPA action on July 4, 2006, above) on July 22, 1999 (in docket R99-12). Later, USEPA

adopted the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR) on January 14,

2002 (67 Fed. Reg. 1812), and the Board adopted it on December 19, 2002 (in docket R03-4).

The LT2ESWTR is a companion to the Stage 2 DBPR (see the entry for the USEPA action of

January 4, 2006, above).

January 27, 2006 (71 Fed. Reg. 4644)

USEPA corrected the January 4, 2006 Stage 2 DBPR.

January 30, 2006 (71 Fed. Reg. 4968)

USEPA corrected the January 5, 2006 LT2ESWTR.

February 6, 2006 (71 Fed. Reg. 6136)

USEPA again corrected the January 5, 2006 LT2ESWTR.

June 29, 2006 (71 Fed. Reg. 37168)

USEPA again corrected the January 4, 2006 Stage 2 DBPR.

November 8, 2006 (71 Fed. Reg. 65574)

USEPA adopted the Ground Water Rule (GWR). Compliance with the federal GWR is

required by December 1, 2009. The GWR is intended to increase protection against microbial

pathogens in public water systems that use ground water sources. Under the GWR, disinfection

is required as a treatment technique for all public water systems, including surface water systems

and ground water systems, as necessary. The GWR targets ground water systems that are

susceptible to fecal contamination, instead of requiring disinfection for all ground water systems.

---

4

The GWR requires ground water systems that are at risk of fecal contamination to take corrective

action to reduce cases of illnesses and deaths due to exposure to microbial pathogens.

November 21, 2006 (71 Fed. Reg. 67427)

USEPA corrected the references to analytical methods for use under GWR.

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 identified no related USEPA actions since

December 31, 2006, that further amend the SDWA rules in a way that affects the present

amendments.

USEPA adopted major amendments to the analytical methods on March 12, 2007 and

March 26, 2007, but the relatively minor overlap between those amendments and the rules that

are the subject of this consolidated docket would not justify the further delay that would result

through inclusion of those later amendments to the methods in this docket.

When the Board observes an action outside the nominal timeframe of a docket that

requires expedited consideration, the Board will expedite consideration of those amendments in

the pending docket. 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 action that fulfills these criteria prior to final action on

the present amendments, the Board may include those amendments in the present consolidated

docket R07-2/R07-11 upon final adoption.

Illinois SDWA (Drinking Water) Regulations

In addition to the amendments to the federal SDWA regulations, amendments to certain

other federal regulations occasionally have an effect on the Illinois drinking water rules. Most

notably, 35 Ill. Adm. Code 611.102 includes the incorporation of 40 C.F.R. 136.3(a) and

Appendix B to 40 C.F.R. 136 of by reference. These are federal Clean Water Act methods for

analysis of contaminants in water.

As of the date of this proposal for public comment, USEPA adopted the major

amendments to the analytical methods on March 12, 2007 and March 26, 2007, mentioned

above. No Board action will be required at this time to update the version of 40 C.F.R. 136

incorporated by reference in Part 611 to include the amendments.

TIMETABLE FOR COMPLETION OF THIS RULEMAKING

Under Section 7.2 of the Act (415 ILCS 5/7.2(b) (2004)), the Board must complete this

rulemaking within one year of the date of the earliest set of federal amendments considered in

this docket. USEPA adopted the earliest federal amendments that required Board attention on

January 4, 2006, so that the deadline for Board adoption of these amendments under that

provision was January 4, 2007.

Section 7.2(b), however, further provides for extension of the deadline for final Board

action by adoption of a Board order and publication of a Notice of Public Information on

Proposed rules that extends the deadline. By orders dated December 21, 2006 and April 19,

2007, the Board twice used this provision to extend the deadline. Delays, compounded by the

volume and complexity of the present amendments, made the extensions necessary. The final

Board action to adopt these amendments is now August 6, 2007.

Considering the proposal of these amendments on this date, the Board presently projects

the following will occur in the progress towards completion of these amendments:

PUBLIC COMMENTS

The Board will receive public comments on this proposal for 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 expects to file any adopted rules with the Secretary of State immediately

after adoption, but no later than August 6, 2007, consistent with the Board’s April 19, 2007

extension order.

DISCUSSION

The following discussion begins with a description of the amendments undertaken in

direct response to the federal action involved in this proceeding. The discussion closes with a

description of the miscellaneous amendments that are not directly derived from the federal

action, but which the Board routinely includes in these update dockets as necessary.

Discussions of the Federal Actions

Stage 2 Disinfectants and Disinfection Byproducts Rule--Sections 611.101, 611.160, 611.310,

611.312, 611.381, 611.382, 611.383, 611.385, 611.680, 611.685, 611.860, 611.881, and

611.883; Subparts W and Y; and Appendices C, G, and H

The USEPA action of January 4, 2006 (70 Fed. Reg. 59848) adopted the Stage 2

Disinfectants and Disinfection Byproducts Rule (DBPR). The Stage 2 DBPR is an extension of

the existing Stage 1 DBPR, adopted by USEPA on December 16, 1998 (at 63 Fed. Reg. 69390)

and by the Board on July 22, 1999 (in docket R99-12). The two stages of the DBPR regulate

drinking water disinfection practices and the content of disinfection byproducts in drinking

water. The DBPR is a companion to the Enhanced Surface Water Treatment Rule (see the next

entry below). The federal amendments include corrections to existing regulations and to the

existing Stage 1 DBPR.

USEPA intended the Stage 2 DBPR to further reduce the risks of cancer and reproductive

and other adverse health effects associated with disinfection byproducts. The Stage 2 rule

applies to any community water supply or non-transient, non-community water system that adds

a disinfectant other than ultraviolet light to drinking water. It includes maximum contaminant

level standards and monitoring, reporting, and public notification requirements for total

trihalomethanes (TTHMs)

1

and haloacetic acids (HAA5)

2

.

There are two aspects to implementation of the Stage 2 DBPR. The two aspects correlate

with the two new subparts added to the federal regulations. In the first aspect, based on new

federal subpart U (which corresponds with new Subpart W in the Illinois rules), a supplier must

complete an initial distribution system evaluation (IDSE). The IDSE establishes monitoring

locations and schedules for monitoring TTHM and HAA5, and it determines the occurrence of

TTHM and HAA5 in the distribution system. In the second aspect, based on new federal subpart

V (which corresponds with new Subpart Y in the Illinois rules), the supplier must engage in

continued compliance monitoring. That monitoring demonstrates compliance with the maximum

contaminant levels (MCLs) for TTHM and HAA5 for all systems and with the maximum

disinfectant residuals (MRDLs) for chlorine and chloramine for consecutive systems.

Compliance with the IDSE aspect of the Rule occurs in three phases. In the first, the

supplier must submit either a standard monitoring plan or a system-specific study plan. A

standard modeling plan includes a schematic diagram of the supplier’s entire distribution system

that indicates the dates and locations where the supplier intends to collect monitoring samples.

1

TTHM is the sum of the concentrations of all the trihalomethane compounds (THMs). The

THMs are defined as including four compounds: trichloromethane (chloroform),

dibromochloromethane, bromodichloromethane, and tribromomethane (bromoform).

2

HAA5 is the sum of the concentrations of haloacetic acid compounds, which are defined to

include five compounds: monochloroacetic acid, dichloroacetic acid, trichloroacetic acid,

monobromoacetic acid, and dibromoacetic acid.

---

7

A system-specific study plan is based either on existing monitoring data or on extended period

hydraulic modeling of the supplier’s distribution system. Under the second phase of the IDSE

requirements, the supplier must complete its standard monitoring or system-specific study based on

the plan that it submitted in the first phase. The third phase requires the supplier to submit its IDSE

report, which includes recommendations and justifications for TTHM monitoring locations and

dates under the second aspect of the Rule: “Subpart Y” monitoring.

3

Alternatively, a supplier may apply for “40/30” certification.

4

A 40/30 certification is

available to a supplier that has monitored for TTHM and HAA5 for eight consecutive calendar

quarters and had no samples exceed threshold limits for these contaminants. A supplier that

receives 40/30 certification does not have to submit a standard monitoring plan or a system-

specific study plan, but the Agency may still require the supplier to submit proposed monitoring

locations and engage in monitoring. The rules further provide that a very small system supplier

(one that serves fewer than 500 people) that has taken samples for TTHM and HAA5 does not

need to submit a standard monitoring plan or a system-specific study plan.

The second aspect of the Stage 2 BDPR is TTHM and HAA5 compliance monitoring.

The monitoring locations and dates are based on the approved IDSE from the first aspect of the

State 2 Rule. Suppliers that have received either 40/30 certification or a small system waiver

must assemble and maintain a Subpart Y monitoring plan.

Under both the IDSE requirements and the Subpart Y compliance monitoring

requirements, the required number of sampling locations and the required sampling frequency

varies, depending on the supplier. Generally, larger suppliers must monitor more frequently at

more locations, and a supplier that uses surface water or groundwater under the direct influence

of surface water must monitor more frequently and at more locations than one using

groundwater. Subpart Y monitoring also allows less frequent (reduced) monitoring if the

locational running annual average (LRAA) for TTHM and HAA5 are below threshold levels.

Conversely, more frequent monitoring may be required where the LRAA exceeds twice the

threshold levels.

The deadlines for completion of the various activities required under the Stage 2 DBPR

are staggered, depending on system size. Suppliers with larger populations served must

complete the activities earlier than those serving smaller populations. The earliest compliance

deadlines relate to submission of the standard monitoring plan or system-specific study plan or to

application for 40/30 certification. A supplier serving 100,000 or more persons must have

submitted the documents by October 1, 2006. One serving fewer than 10,000 persons is not

3

It is called “Subpart V” monitoring under the federal rules. The Board found it necessary to

designate this as “Subpart Y,” since Subpart V under the Illinois regulations is already

designated for public notification requirements.

4

The certification is that the system does not exceed 40 μg/ℓ TTHM or 30 μg/ℓ HAA5. These

are called “threshold levels” in this opinion, since the actual numeric values are of no value for

the purposes of this discussion.

required to do so until April 1, 2008. The second deadline is for completion of the standard

monitoring or system-specific study, for which the submission deadlines range from September

30, 2008 to March 31, 2010, depending on system size. Suppliers must submit their completed

IDSE reports by January 1, 2009 to July 1, 2010, depending on the size of the population served.

Compliance with the Subpart Y monitoring requirements is required by April 1, 1012, for a

supplier that serves 100,000 persons or more, ranging to October 1, 2014, for a supplier that

serves fewer than 10,000 persons which is required to monitor for

Cryptosporidium

under the

Stage 1 DBPR requirements.

USEPA subsequently corrected the Stage 2 DBPR. The corrections occurred on January

27, 2006 (71 Fed. Reg. 4644) and June 29, 2006 (71 Fed. Reg. 37168).

The Board added the Stage 2 DBPR requirements to the Illinois regulations without

substantive deviation. The significant deviations from the federal text are structural changes.

First, the Board had to change the subpart designations for the requirements. Under the federal

rules, the IDSE requirements are designated subpart U, and the Stage 2 monitoring requirements

are subpart V. In the existing Illinois regulations, subpart U contains the consumer confidence

reporting provisions, and subpart V contains the public notification requirements. Thus, the new

Stage 2 DBPR provisions relating to the IDSE become subpart W in the Illinois rules, and the

monitoring requirements become subpart Y.

The second structural change is the reformatting of tabulated information into standard

paragraphs. USEPA placed such requirements as compliance deadlines, sampling location and

frequency, and a summary of the monitoring requirements into tables. The Illinois

Administrative Code format requirements impose margin restrictions, with the margins

narrowing with increasing indent levels. Thus, the Board had the options of placing the

tabulated information into appendices or reformatting it into the standard paragraph format.

Since some of the tabulated material was formatted such that the Board would have had

difficulty fitting it on a page, the Board did not retain it in a tabular format. For these reasons,

the Board chose to reformat the tabulated information into a paragraph format. When changing

the format, the Board added footnotes to the federal table as separate subsections, located and

worded in a way that associates the noted material to the appropriate text. While making this

change mainly allowed an exact correspondence between the federal and state numbering of

provisions, movement of the footnotes required a deviation in numbering: 40 C.F.R.

141.620(c)(6) through (c)(8) became 35 Ill. Adm. Code 611.920(c)(8) through (c)(10). The

following list indicates the USEPA tables converted to text:

40 C.F.R. 141.600(c)(1)

40 C.F.R. 141.623(a)

Section 611.973(a)(1) through (a)(14)

---

A third structural change to the text of the federal rules is the addition of definitions for

terms that are intended to have a standardized meaning in the rules. USEPA added definitions

for “combined distribution system,” “consecutive system,” “dual sample set,” “finished water,”

“GAC20,” “locational running annual average,” and “wholesale system.” These are all

standardized terms in the Stage 2 DBPR. The Board added definitions for other standardized

terms: “40/60 certification,” “initial distribution system evaluation,” “standard monitoring,”

“Subpart I system,” “Subpart I compliance monitoring,” “Subpart Y compliance monitoring,”

“system-specific study plan,” and “very small system waiver.” While a standardized meaning is

intended for each term, USEPA did not include their definitions. The Board added the

definitions derived from the meanings apparent from the context of the regulations.

A fourth structural change from the literal federal text relates to Agency decision-making

under the Stage 2 rule. Several provisions in the rule provide for State decisions that determine

the applicability of segments of the rule. For example, 40 C.F.R. 141.600(c)(2) (corresponding

with Section 611.920(c)(2)) provides that the State may determine that a combined distribution

system does not include certain consecutive systems or wholesale systems, for the purposes of

determining the size of the system to ascertain an effective date for the IDSE requirements.

Another provision, 40 C.F.R. 141.602(a)(1)(ii)(F) (corresponding with Section

611.922(a)(1)(B)(vi)) provides that the State may reject existing monitoring data, and that the

supplier must replace that data on a State-approved schedule. There are several other provisions

in the Stage 2 DBPR that require decisions made by the State which determine either the

applicability of segments of the rules or the course of action that the supplier must take.

The Board reviewed all the determinations assigned by USEPA to the State, to determine

their nature and the appropriate State agency to make the determination. The Board found them

uniformly to be the types of determinations that the Agency could best make in the nature of a

permit decision. The Board assigned all of these determinations to the Agency. The Board

chose to use the existing Section 611.110 mechanism of the “special exception permit” (SEP) for

each determination. The SEP procedure requires the Agency to make each determination in

writing, and it expressly provides for the mechanism of Board review to challenge the Agency

determination. The following table indicates the provisions in which the SEP is used as the tool

for Agency determinations required under the Stage 2 DBPR, indicating the federal provision

Finally, the Board found it necessary to incorporate requirements from 40 C.F.R. 142 into

the Illinois drinking water regulations. Generally, 40 C.F.R. 141 contains all the National

Primary Drinking Water Regulations (NPDWRs). The companion regulations of 40 C.F.R. 142

pertain to implementation of the NPDWRs. Significantly, federal part 142 sets forth the state

primacy requirements. On occasion, however, USEPA includes elements in the state primacy

requirements that the Board must include with the substantive NPDWRs.

As a segment of the Stage 2 DBPR, USEPA authorized the State to modify the

monitoring requirements for wholesale and consecutive systems on a case-by-case basis. The

text of 40 C.F.R. 142.16(m), which USEPA added for the authorization, however, includes only

one aspect of any such modification of the monitoring requirements: that every system must

have at least one compliance monitoring location. This is not enough to provide a framework for

Agency decision-making. The Board could not include a provision in the Illinois rules that

would allow the Agency to reduce the monitoring without providing the basis on which the

Agency could make a determination to allow it.

Review of the

Federal Register

discussion of modification of the monitoring

requirements, indicates the factors that USEPA intended the State to consider when deciding to

allow the reduced monitoring. USEPA stated as follows:

EPA believes that assigning compliance monitoring requirements appropriately

throughout the combined distribution system requires a case-by-case

determination based on factors such as amount and percentage of finished water

provided; whether finished water is provided seasonally, intermittently, or full-

time; and improved DBP occurrence information. . . . States may consider

modifications to Stage 2 compliance monitoring requirements for consecutive

systems on a case-by-case basis as allowed by § 141.29 or under the special

primacy condition at § 142.16(m)(3) by taking all these factors into consideration.

In making these case-by-case determinations, the State will be able to use its

system-specific knowledge, along with the IDSE results, to develop an

appropriate monitoring plan for each system within the combined distribution

system. 71 Fed. Reg. 388, 430-31 (Jan. 4, 2006).

The Board used this description of what USEPA intended and other segments of the

federal rules to add the framework for an Agency determination to modify the monitoring

requirements for consecutive and wholesale systems on a case-by-case basis. The Board

included Section 611.161 in the Illinois rules, derived from new 40 C.F.R. 142.16(m) and the

preamble discussion in the

Federal Register

. Subsection (a) sets forth the system-specific

information that the Agency must consider, as outlined in the

Federal Register

discussion quited

above. Subsection (b) includes the minimum one compliance monitoring location limitation

from 40 C.F.R. 142.16(m). Subsection (c) was added to parallel 40 CFR 141.622(c)

(corresponding with Section 611.972(c) in the Illinois rules), which requires Agency

consideration when changes occur that could affect the federal subpart V (Illinois Subpart Y)

monitoring plan. Subpart (d) would restrain the Agency from relaxing the monitoring until after

USEPA has authorized the Illinois rules by granting primacy to the State.

A small number of changes from the long-standing federal text are differences in

nomenclature. Principally, the Board opted to restrict the meanings of “system” and “supplier.”

Following the usage established in Safe Drinking Water Act Regulations, R88-26 (Aug. 9, 1990)

at pp. 39-40, the Board has used “system” to refer to the physical plant used to process and

deliver potable water and to use “supplier” to refer to the person that owns or operates the water

system. In some instances, it was necessary to use “system supplier,” as in Section

611.382(b)(1)(C) (“Subpart B system supplier”), 611.802(g) (“consecutive system supplier”),

and 611.921(b)(1)(K) (“groundwater system supplier”). Other changes include the shift from the

second person “you” and “your” to the third person “the supplier,” “it,” “its,” etc. Another

change is continuation of the Board’s past practice of changing requirements in the plural in the

federal text to singular in the corresponding Illinois rule.

One aspect of the Stage 2 DBPR that the Board has not changed are the past compliance

deadlines. For example, a supplier that serves 100,000 or more persons was to have submitted

its standard monitoring plan, system-specific study plan, or 40/30 certification by October 1,

2006. A supplier that provides water to 50,000 to 99,999 persons was to have submitted the

appropriate of these documents by April 1, 2007. These past dates would present problems were

the Board to impose them as a matter of State law, but the Board does not intend to do so.

Retention of these past dates is a required part of the Board’s “identical-in-substance” mandate

under Section 7.2 of the Act. 415 ILCS 5/7.2 (2004). The Board perceives that the suppliers to

whom these dates apply were to have completed them as a matter of federal law. By retaining

the past dates in the text of Sections 611.920(c)(1)(A) and (c)(1)(B) and 611.923(a)(1) and (a)(2)

in the Illinois rules, the Board avoids inconsistency with the corresponding provisions of 40

C.F.R. 141.600(c)(1)(i) and (c)(1)(ii) and 141.603(a)(1) and (a)(2). The Board believes that the

past-tense wording chosen to refer to the past dates in these provisions avoids the possibility of

improper

ex post facto

of these dates as a matter of State law.

The tables that appear beginning on page 20 of this opinion list and briefly describe the

deviations from the literal text of the federal rules and the changes made in the existing text of

the Illinois rules that were not derived from federal amendments. The Board requests public

comment on the incorporation of the January 4, 2006 Stage 2 DBPR into the Illinois drinking

water regulations.

Long Term 2 Enhanced Surface Water Treatment Rule--Sections 611.101, 611.160, and

611.911; Appendix G; and Subpart Z

USEPA adopted the Long Term 2 Enhanced Surface Water Treatment Rule

(LT2ESWTR) on January 5, 2006 (70 Fed. Reg. 59848). The LT2ESWTR is a companion to the

Stage 2 DBPR. The LT2ESWTR is aimed at achieving enhanced protection against

Cryptosporidium

and

Giardia lamblia

. It is an extension of a series of successive federal rules

relating to surface water treatment. USEPA adopted the Surface Water Treatment Rule (SWTR)

and the Total Coliform Rule (TCR) on June 29, 1989 (at 54 Fed. Reg. 27486 and 27544,

respectively). It then adopted the Interim Enhanced Surface Water Treatment Rule (IESWTR)

on December 16, 1998 (at 63 Fed. Reg. 69478). On January 14, 2002 (67 Fed. Reg. 1812),

USEPA adopted the Long Term 1 Enhanced Surface Water Treatment Rule (LT1ESWTR). The

---

12

Board adopted the SWTR on May 24, 1990 (in docket R88-26), the IESWTR on July 22, 1999

(in docket R99-12), and the LT1ESWTR on December 19, 2002 (in docket R03-4).

The LT2ESWTR adds a new subpart W to the federal rules (which corresponds with new

Subpart Z in the Illinois rules). Its various requirements have two aspects: source water

monitoring and water treatment for

Cryptosporidium

reduction. The LT2ESWTR requires a

supplier that uses surface water or groundwater under the influence of surface water to monitor

source water for

Cryptosporidium

. The monitoring is to occur in two rounds, with the second

round to be completed nine years after the first. As with the Stage 2 DBPR, suppliers that serve

larger populations must complete each round of monitoring earlier than those that serve smaller

populations. For example, a supplier that serves 100,000 persons or more must have completed

the monitoring by October 1, 2006, but one that serves fewer than 10,000 persons and monitors

for

Cryptosporidium

does not need to begin first round monitoring until April 1, 2010.

How the first-round source water monitoring requirements apply to suppliers also varies.

Among suppliers that serve 10,000 persons or more, monitoring must occur at least monthly,

with filtered system suppliers monitoring for

Cryptosporidium

,

E. coli

, and turbidity, and

unfiltered system suppliers monitoring for

Cryptosporidium

only. A filtered system supplier that

serves fewer than 10,000 persons is required to monitor for

E. coli

for 12 months, but may avoid

this monitoring if it monitors for

Cryptosporidium

for 12 months or 24 months, depending on the

frequency of monitoring, or if the State approves an alternative indicator. An unfiltered system

supplier that serves fewer than 10,000 persons is required to monitor for

Cryptosporidium

for 12

months or 24 months, depending on the frequency of monitoring. Alternatively, a supplier may

avoid the first-round monitoring requirements if it provides treatment for

Cryptosporidium

. A

filtered system supplier must provide treatment to achieve at least a 5.5-log (316,000-fold)

reduction in

Cryptosporidium

to avoid first-round monitoring, and an unfiltered system must

provide 3-log (1,000-fold) reduction.

Based on the results of the first-round monitoring, a filtered system supplier is placed

into one of four treatment classifications that USEPA calls “bins.” The bins are numbered one

through four. The higher the incidence of

Cryptosporidium

in the first-round monitoring, the

higher the supplier’s bin classification. The higher the bin classification, the greater the level of

log-reduction in

Cryptosporidium

required of the supplier through treatment. Unfiltered system

suppliers do not receive a bin classification. Instead, an unfiltered system that has a mean

Cryptosporidium

concentration greater than a low threshold value must provide a 1-log

inactivation greater than a supplier whose

Cryptosporidium

concentration is below that value.

The deadline for compliance with the

Cryptosporidium

treatment requirements varies

from April 1, 2012, for a supplier that serves 100,000 or more persons, to October 1, 2014, for a

supplier that serves fewer than 10,000 persons. The treatment requirements comprise a series of

“toolbox options” that a supplier might employ to gain log-reduction credits. For example,

pursuing a watershed control program or using two-stage lime softening confers 0.5-log

reduction credit, and slow sand filtration confers 3.0-log credit when used as a primary filtration

process. The log credit conferred by disinfection depends on the disinfectant used and the

disinfectant concentration-contact time (CT). The regulations set forth CT tables for chlorine

dioxide and ozone that also account for the water temperature, and one for ultraviolet (UV)

---

13

radiation that sets forth numbers that are independent of temperature. Disinfection can confer

from 0.25-log to 4.0-log credit.

The final LT2ESWTR requirements to take effect are the second-round source water

monitoring requirements. Suppliers must begin their second-round monitoring after the deadline

for compliance with the

Cryptosporidium

treatment requirements. The deadline for beginning

second-round monitoring varies from April 1, 2015, for a supplier that serves 100,000 or more

persons, to October 1, 2019, for a supplier that serves fewer than 10,000 persons which is

required to engage in monitoring for

Cryptosporidium

.

The Board added the LT2ESWTR requirements to the Illinois regulations without

substantive deviation. As with the Stage 2 DBPR discussed above, the significant deviations

from the federal text are structural changes. First, the Board had to change the subpart

designation for the requirements. Under the federal rules, the LT2ESWTR requirements are

designated subpart W. In the Illinois regulations, however, new Subpart W adds IDSE

requirements from the Stage 2 DBPR. Thus, the new LT2ESWTR provisions become subpart Z

in the Illinois rules.

The second structural change is the reformatting of tabulated information into standard

paragraphs, just as discussed above relating to the Stage 2 DBPR. USEPA placed into tables

requirements such as compliance deadlines, bin classifications,

Cryptosporidium

treatment

requirements, the microbial toolbox into tables, and the log credits for the various CT values and

UV doses. As stated above, the Board had the options of placing the tabulated information into

appendices or reformatting it into the standard paragraph format. The Board chose to reformat

the tabulated information relating to compliance deadlines, bin classifications,

Cryptosporidium

treatment requirements, and the microbial toolbox into a paragraph format. When changing the

format, the Board added footnotes to the federal table as separate subsections, located and

worded in a way that associates the noted material to the appropriate text. While making this

change mainly allowed an exact correspondence between the federal and state numbering of

provisions, movement of the footnotes required a deviation in numbering: 40 C.F.R. 141.711(a)

became 35 Ill. Adm. Code 611.1011(a)(1) through (a)(13). The following list indicates the

USEPA tables converted to text:

The Board, however, retained the tabulated format for the log credits for the various CT

values and UV doses in new Tables H through J in the rules. The following list indicates the

three tables retained in tabular format and codified as tables to Part 611:

Table I to Part 611

40 C.F.R. 141.720(d)(1)

Table J to Part 611

As with the Stage 2 DBPR, the Board opted to restrict the meanings of “system” and

“supplier” in the LT2ESWTR. Also as with the Stage 2 DBPR, one aspect of the Stage 2 DBPR

that the Board has not changed are the past compliance deadlines. The segments of the above

discussion of the Stage 2 DBPR pertaining to the usage apply to this discussion of the

LT2ESWTR. Finally, the Board chose to require the use of the SEP procedure of Section

611.110 for the many Agency determinations under the LT2ESWTR, just as under the Stage 2

BDPR. The following table indicates the provisions in which the SEP is used as the tool for

Agency determinations required under the LT2ESWTR, indicating the federal provision from

The tables that appear beginning on page 20 of this opinion list and briefly describe the

deviations from the literal text of the federal rules and the changes made in the existing text of

the Illinois rules that were not derived from federal amendments. The Board requests public

comment on the incorporation of the January 4, 2006 Stage 2 DBPR into the Illinois drinking

water regulations.

Groundwater Rule--Sections 611.490, 611.524, 611.883, 611.902, and 611.903; Appendices

A, G, and H; and Subpart S

USEPA adopted the Groundwater Rule (GWR) on November 8, 2006 (70 Fed. Reg.

65574). The GWR applies microbial quality standards to suppliers using groundwater sources.

The LT2ESWTR is aimed at achieving increased protection against microbial pathogens.

Instead of applying disinfection requirements to all groundwater source suppliers, the GWR

targets suppliers that are at risk of contamination. Compliance with the provisions of the GWR

---

15

is required by December 1, 2009, except that the Agency is not required to complete the initial

sanitary surveys upon which many requirements depend until December 31, 2012, for a

community water system, or December 31, 2014, for a non-community water system.

The GWR adds a new subpart S to the federal rules (which corresponds with new Subpart

S in the Illinois rules). Its various requirements have two aspects: (1) initial study and

monitoring to determine whether a system is susceptible to fecal contamination and (2) the

requirement for disinfection as a treatment technique to control microbial contamination.

The GWR requires the State to conduct sanitary surveys of each supplier to determine the

susceptibility of its system to contamination. The supplier is required to provide all requested

pertinent information to the State to aid the survey. The sanitary survey examines the water

sources, facilities, equipment, operation, maintenance, and monitoring compliance of a supplier

to determine the adequacy of its system for protection against microbial contaminants. The

Agency must conduct the initial sanitary survey for each supplier by December 31, 2012. The

Agency must repeat the sanitary survey of each supplier’s system no less frequently than every

three years, for a community water system that fulfills certain, specified conditions or for a non-

community water system (including any combination of removal or disinfection).

The GWR includes source water monitoring requirements. Where a groundwater system

supplier either does not provide a 4-log reduction of viruses through treatment, it must engage in

source water monitoring under the GWR. Similarly, if a sample from the supplier’s routine

monitoring under existing requirements tests positive for total coliforms, the supplier must

engage in source water monitoring.

If the State identifies a “significant deficiency” in the supplier’s system as a result of the

survey, the supplier must undertake corrective action approved by the State to address the

deficiency. Similarly, if source water monitoring under the GWR indicates fecal contamination

in the source water, the supplier must undertake approved corrective action. The appropriate

corrective actions are (1) correction of the significant deficiencies, (2) providing an alternative

source of water, (3) elimination of the source of the contamination, or (4) providing treatment

that produces a 4-log reduction in viruses. If a supplier applies chemical disinfectant to its water

as part of its corrective action, it must monitor disinfectant residual on an ongoing basis.

Similarly, if a supplier employs membrane filtration, it must monitor the effectiveness of the

process.

The Board added the GWR requirements to the Illinois regulations without substantive

deviation. As with the Stage 2 DBPR and LT2ESWTR changes discussed above, the significant

deviations from the federal text are structural. First, the Board had to reformat one table into

standard paragraph format within the body of the rules. Thus, the table of analytical methods at

40 C.F.R. 141.402(c)(2) has become Section 611.802(c)(2)(A) through (c)(2)(D). The Board

placed the footnote material into the associated segments of text, which required the addition of

Board notes appended to subsections (c)(2)(A) (for the purposes of subsections (c)(2)(A)(vi) and

(c)(2)(A)(vii)), (c)(2)(B)(ii), and (c)(2)(B)(iii).

---

16

As with the Stage 2 DBPR and the LT2ESWTR, the Board opted to restrict the meanings

of “system” and “supplier” in the GWR. Also as with the Stage 2 DBPR, the Board found it

necessary to add definitions not added to the general definitions section by USEPA. The Board

added definitions of “groundwater,” “hydrogeologic sensitivity assessment,” “sanitary survey,”

and “significant deficiency.” The Board added material from new 40 C.F.R. 141.400(b) to the

existing definition of “GWS” in the Illinois rules, which was based on 40 C.F.R. 141.23(b)(2)

and the note to 141.24(f)(2) to create the definition of “groundwater system.” The Board added

the definition of “hydrogeologic sensitivity assessment” from new 40 C.F.R. 141.400(c)(5). The

Board modified the existing definition of “sanitary survey, ” which was based on the federal

definition of the term in 40 C.F.R. 141.2, to accommodate the new information in the definition

of the term added to the state primacy requirements at 40 C.F.R. 142.16(o)(2).

5

Finally, the Board added a definition of “significant deficiency” to the rules. This term

appears in several segments of the GWR. Consequences flow from an Agency finding of

significant deficiency. Public understanding of the regulations benefits from inclusion of a

definition of such a significant term, but USEPA does not define the term in either the NPDWRs

or the preamble discussion. Instead, in the primacy requirements of 40 C.F.R. 142.16(o)(2)(iv),

USEPA requires the State to give examples of significant deficiencies as part of the State

primacy application. The requirement states as follows:

The State must define and describe in its primacy application at least one specific

significant deficiency in each of the eight sanitary survey elements in paragraphs

(o)(2)(i)(A) through (o)(2)(i)(H) of this section. Significant deficiencies include,

but are not limited to, defects in design, operation, or maintenance, or a failure or

malfunction of the sources, treatment, storage, or distribution system that the

State determines to be causing, or have potential for causing, the introduction of

contamination into the water delivered to consumers. 40 C.F.R. 142.16(o)(2)(iv),

as added at 71 Fed. Reg. 65574, 65660 (Nov. 8, 2006).

The Board used this inclusive description of a significant deficiency as the definition for the

term, to increase comprehension of the rules while keeping them identical-in-substance to the

federal rules.

The tables that appear beginning on page 20 of this opinion list and briefly describe the

deviations from the literal text of the federal rules and the changes made in the existing text of

the Illinois rules that were not derived from federal amendments. The Board requests public

comment on the incorporation of the January 4, 2006 Stage 2 DBPR into the Illinois drinking

water regulations.

Finally, the Board chose to require the use of the SEP procedure of Section 611.110 for

the many Agency determinations under the GWR, just as under the Stage 2 BDPR and

LT2ESWTR. The following table indicates the provisions in which the SEP is used as the tool

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 found in the text in the course of 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 discussed above, the most recent versions of the Code of Federal

Regulations available to the Board is the July 1, 2005 edition for USEPA regulations (Title 40).

Thus, the Board has updated all citations to Title 40 to the 2006 edition of the Code of Federal

Regulations, 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.

---

18

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 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 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.”

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. Table 1 sets forth the miscellaneous deviations from the federal

text, and Table 2 itemizes the corrections to the pre-amended base text of the rules in detail.

Table 1 begins on page 20 of this opinion, and Table 2 begins on page 173. There is no further

discussion of most of the deviations and revisions elsewhere in this opinion.

Discussion of Corrective Amendments

The Board has traditionally used the occasion of these identical-in-substance updates to

correct segments of the base text of the Illinois regulations. These corrections are non-

substantive in effect. The Board is including a significant number of non-substantive corrections

in this docket.

When a necessary minor correction comes to the attention of the Board, Board staff

makes a note of the correction, and set it aside until the next opportunity to make the correction.

The next opportunity generally presents itself when the section involved is next opened for

amendment as a result of amendments to the corresponding federal text. The Board has

cataloged a small number of changes since the last SDWA update docket,

SDWA Update,

USEPA Regulations (July 1, 2005 though December 31, 2005), R06-15 (Oct. 5, 2006).

The Board will not discuss the bulk of the particular corrective amendments in this

segment of this discussion. Only one warrants specific discussion. That discussion follows this

paragraph. The corrections are itemized in the Table 1, which begins on page 20 of this opinion.

The Board requests that the Agency, JCAR, and the regulated community review the table and

the text of the corrections. The Board requests comment on the corrections. The Board also

asks for the assistance of the Agency, JCAR, and the regulated community in the process of

---

19

spotting and correcting errors or omissions in the rules. The Board requests that interested

persons submit suggestions for the correction of any errors of which they become aware. The

Board will either include the corrections in this docket or catalog them for future revisions, if the

suggestions relate to segments of the text that are not already involved in this proceeding and the

Board cannot add them.
