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 (2000)), the Board today 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) (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 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 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) (August 24, 2000), R00-10,

USEPA and the Agency have both commented that the unregulated contaminant

monitoring provisions are not segments of the federal SDWA rules that the Board is

required to adopt and maintain.

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. 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 R02-5.

return of recycled flows to the filtration process that could potentially

threaten the microbiologic integrity of the treatment process.

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 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, 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.”

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, 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, and 611.680

On January 16, 2001 (66 Fed. Reg. 3770), USEPA adopted 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). 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)

(July 22, 1999), R99-12, 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 requests public comment on our incorporation of the January 16, 2001 federal

amendments to the interim enhanced surface water rule and the Stage 1 disinfectants and

disinfection byproducts rule into the Illinois drinking water regulations.

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:

note

The common understanding at USEPA, the Agency, and elsewhere appears to be that the

federal arsenic NPDWR is being held in abeyance, at least until February 22, 2002, the date until

which USEPA ultimately delayed the effectiveness of the amendments while it revisits the

associated technical issues involved. But, the Board must take action now to adopt these rules as

Illinois law. Under the Act, it is the date of the

Federal Register

notice that adopts amendments

that dictates the deadline for Board action. USEPA adopted the arsenic rule on January 22,

2001, and it has not withdrawn or otherwise nullified the rule, even if USEPA did delay the

effective date to revisit the issues. Sections 7.2 and 22.4(a) of the Act (415 ILCS 5/7.2 and

22.4(a) (2000)) mandate that the Board adopt the arsenic rule as it stands by January 16, 2002.

This requires the Board to proceed to propose these amendments without regard to the fact that

January 16, 2002 is one year from the date of the earliest federal amendments involved in the

six-month update period involved in this docket.

USEPA is unsettled on the issues involved and may well act by February 22, 2002 to replace the

current arsenic rule with one that is radically different.

If USEPA adopts another extension of the effective date or a different rule before the

Board has filed amendments based on this proposal, the Board will act to incorporate the federal

changes into these amendments before they become final and effective. If, on the other hand, as

now appears more likely, USEPA proceeds to amend the arsenic rule after the Board has fulfilled

our mandate and adopted final amendments based on this proposal, the Board will timely amend

the arsenic rule in a future rulemaking. The Board will act as promptly as practical to assure that

the Illinois drinking water regulations remain consistent with the federal rules.

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 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 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 (October 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 (August 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.

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 requests public comment on our incorporation of the January 16, 2001 federal

amendments to the radiologic contaminant rules into the Illinois drinking water regulations.

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

National secondary MCLs exist for these contaminants, but the Board is not required to

incorporate them into the Illinois regulations, since they are not NPDWRs. (See 415 ILCS

5/17.5 (2000) and 40 C.F.R. 143.1 (2000).)

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 requests 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 request 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.

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.

Discussion of Miscellaneous Housekeeping Amendments

The tables below list numerous corrections and amendments that are not based on current

federal amendments. The first table (beginning immediately below) includes deviations made in

this Proposal for Public Comment from the verbatim text of the federal amendments. The

second table (beginning below at page 19) contains corrections and clarifications that the Board

made in the base text involved in this proposal. The amendments listed in this second table are

not directly derived from the current federal amendments. Some of the entries in these tables are

discussed further in appropriate segments of the general discussion beginning at page 4 of this

opinion.
