Proposed Rule.  Proposal for Public Comment. 
 
OPINION AND ORDER OF THE BOARD (by N.J. Melas): 
 
Under Sections 7.2 and 13.3 of the Environmental Protection Act (Act) (415 ILCS 5/7.2 
and 13.3 (2000)), the Board today proposes amendments to the Illinois regulations that are 
“identical in substance” to wastewater pretreatment regulations that the United States 
Environmental Protection Agency (USEPA) adopted to implement Sections 307(b), (c), and (d) 
and 402(b)(8) and (b)(9) of the federal Water Pollution Control Act (FWPCA) (33 U.S.C. 
§§ 1317(b), (c), and (d) and 1342(b)(8) and (b)(9) (1994)).  The nominal timeframe of this 
docket includes federal wastewater pretreatment amendments that USEPA adopted in the period 
January 1, 2001 through June 30, 2001. 
 
Sections 7.2 and 13.3 provide for quick adoption of regulations that are identical in 
substance to federal wastewater pretreatment regulations that USEPA adopts to implement 
Sections 307(b), (c), and (d) and 402(b)(8) and (b)(9) of the FWPCA.  Section 13.3 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 wastewater pretreatment regulations are found at 40 C.F.R. 400 through 
499. 
 
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 R02-3:  January 1, 2001 through June 30, 2001 Wastewater 
Pretreatment Amendments 
 
USEPA amended the federal wastewater pretreatment regulations on six occasions during 
the period January 1, 2001 through June 30, 2001.  This is summarized below: 
 
66 Fed. Reg. 3466 (January 16, 2001) 
By a direct final rule, USEPA approved the use of updated test procedures for 
 
 2
determination of various contaminants in water and wastewater.  USEPA amended 40 
C.F.R. 136, but later withdrew the amendments on May 15, 2001. 
 
66 Fed. Reg. 3770 (January 22, 2001) 
USEPA adopted effluent limitations and new source performance standards applicable to 
the offshore and coastal subcategories of the oil and gas extraction point source category.  
The amendments pertained only to direct discharges, and did not pertain to any 
pretreatment standards. 
 
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. 30807 (June 8, 2001) 
USEPA corrected its January 22, 2001 (66 Fed. Reg. 3770) effluent limitations and new 
source performance standards for the oil and gas extraction point source category. 
 
66 Fed. Reg. 32774 (June 18, 2001) 
USEPA adopted technical corrections to the test procedures for determination of mercury 
in water and wastewater.  USEPA amended 40 C.F.R. 136, which is incorporated by 
reference in 35 Ill. Adm. Code 310.107.
 
 
66 Fed. Reg. 33134 (June 20, 2001) 
USEPA adopted a correction to its January 22, 2001 (66 Fed. Reg. 6850) effluent 
limitations and new source performance standards applicable to the offshore and coastal 
subcategories of the oil and gas extraction point source category. 
 
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 22, 2001 (66 Fed. Reg. 3770) effluent 
limitations and new source performance standards applicable to sources in the offshore 
and coastal subcategories of the oil and gas extraction point source category.   The same 
is true of the June 8, 2001 (66 Fed. Reg. 30807) and June 20, 2001 (66 Fed. Reg. 33134) 
corrections to the January 22, 2001 amendments.  There are two reasons why no Board 
action is necessary on these three actions.  First, there are no sources in the offshore and 
coastal subcategory in Illinois.  Section 7.2(a)(1) of the Act (415 ILCS 5/7.2(a)(1) 
(2000)) prohibits the Board from adopting regulations that do not apply to facilities in 
this State.  Second, all of the amendments relate to direct discharges to the waters of the 
United States, not to indirect discharges to the collection system of a publicly owned 
treatment works (POTW) that would be subject to wastewater pretreatment standards. 
 
 
 3
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 Wastewater Pretreatment 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 wastewater pretreatment 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 R02-3. 
 
Summary Tabulation of the Federal Action Included in This Docket 
 
June 18, 2001 
(66 Fed. Reg. 32774) 
Technical corrections to the test procedures for determination of 
mercury in water and wastewater in 40 C.F.R. 136. 
 
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 
 
 4
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 has further updated the citations to the 
United States Code
 to the latest official 
edition available, which is the 1994 edition (updated through the supplement 5, January 23, 
2000).  We have further changed the former “as of July 1, 1988” with “ as amended through 
. . .,” setting forth the date of the latest amendments to the individual statute.  The date of the 
latest amendments was January 6, 1999 for Section 1001 of the Criminal Code (18 U.S.C. 1001 
(1994) (relating to false statements), October 31, 1994 for the Clean Water Act (33 U.S.C. 1251 
et seq.
 (1994)), and March 26, 1996 for the Resource Conservation and Recover Act of 1976 (42 
U.S.C. 6901 
et seq.
 (1994)). 
 
The Board has assembled a table to aid in the location of these alterations and to briefly 
outline their intended purpose.  The table sets forth the miscellaneous corrections to the pre-
amended base text of the rules in detail.  The table is set forth and explained beginning on the 
next page of this opinion and order.  There is no further discussion of most of the deviations and 
 revisions elsewhere in this opinion. 
 
Discussion of the Federal Action 
 
Technical Correction to the Methods for Measurement of Mercury in Water—Section 
310.107 
 
On June 18, 2001 (66 Fed. Reg. 32774), USEPA adopted technical corrections to its 
“Guidelines Establishing Test Procedures for the Analysis of Pollutants.”  The corrections 
clarified the use of field blanks for mercury testing under the Clean Water Act.  The corrections 
rectified an omission in the version of “Method 1631:  Mercury in Water by Oxidation, Purge 
and Trap and Cold Vapor Atomic Fluorescence Spectrometry.”  USEPA originally adopted 
Method 1631 on May 26, 1998 (63 Fed. Reg. 28867).  On June 8, 1999 (64 Fed. Reg. 30417), 
USEPA adopted Revision B to this method.  As a result of litigation involving this method, in 
Alliance of Automobile Manufacturers v. EPA, No. 99-1420 (D.C. Cir.), USEPA agreed to 
revise the method relating to the use of field blanks.  To effect the corrections, USEPA added a 
 
 5
reference to Revision C to Method 1631 at 40 C.F.R. 136.3(b)(41).  Incorporating the technical 
corrections, USEPA stated that it would follow through with more substantive amendments to 
Method 1631 in the future. 
 
The Board incorporated the federal technical corrections into the Illinois wastewater 
pretreatment regulations without deviation.  40 C.F.R. 136 is incorporated by reference at 35 Ill. 
Adm. Code 310.107(b).  To incorporate the federal amendments into the Illinois wastewater 
 pretreatment regulations, the Board updates the reference to 40 C.F.R. 136 to include the June 
18, 2001 amendments.  Persons interested in the substance of the underlying federal action 
should refer to the notice that appeared in the January 16, 2001 issue of the 
Federal Register
. 
 
The Board requests public comment on our incorporation of the June 18, 2001 federal 
technical corrections to Method 1631 for determining mercury in water into the Illinois 
wastewater pretreatment regulations. 
 
Discussion of Miscellaneous Housekeeping Amendments 
 
The table below lists numerous corrections and amendments that are not based on current 
federal amendments.  The table includes corrections and clarifications that the Board made in the 
base text involved in this proposal.  Some of the entries in this table are discussed further in the 
general discussion on the previous page of this opinion.
