OPINION AND ORDER OF THE BOARD (by G.T. Girard, R.C. Flemal, N.J. Melas):
On August 30, 2000, the Illinois Environmental Protection Agency (Agency) filed a
proposal for rulemaking (Prop.) to amend the Board’s water “nondegradation” rules at 35 Ill.
Adm. Code 302.105, 303.205 and 303.206. The proposed rules would implement the required
federal concepts of antidegradation and outstanding resource waters for the State of Illinois. The
Agency also proposed amendments to the Board’s procedural rules at 35 Ill. Adm. Code
106.990-106.995 to include provisions for designating outstanding resource waters in Illinois.
On September 7, 2000, the Board accepted the proposal for hearing.
After the Board accepted this matter for hearing, the Board held three hearings before
Board Hearing Officer Marie Tipsord. The first and third hearings (November 17, 2000 and
February 6, 2001), were held in Chicago, Illinois. The second hearing (December 6, 2000), was
held in Springfield, Illinois. Testimony was heard from the Agency, the Department of Natural
Resources (DNR), Illinois Environmental Regulatory Group (IERG), American Bottoms
Regional Wastewater Treatment Facility, Village of Sauget, Illinois, Prairie Rivers Network, the
Environmental Law & Policy Center, Friends of the Fox River, McHenry County Defenders and
the Sierra Club.
1
In addition, all of these participants except the Department filed post-hearing
public comments. The Board received a total of 47 comments prior to the first notice, which
included 42 comments from groups and individuals not named in this paragraph. On June 21,
2001, after reviewing the comments and testimony and making changes to the proposal based on
those comments and testimony, the Board proceeded to first notice with the rules.
2
 
After the Board adopted the first-notice proposal, the Board held a fourth hearing on
August 24, 2001 in Chicago. At that hearing testimony was provided by Toby Frevert
representing the Agency, Dierdre K. Hirner representing IERG, Jack Darin representing Sierra
Club, Illinois Chapter, Cynthia L. Skrukrud representing Friends of the Fox River, and Robert J.

The Prairie Rivers Network, the Environmental Law & Policy Center, Friends of the Fox River,
McHenry County Defenders and the Sierra Club all participated both individually and as a
group. Therefore, when referring to their joint comments and testimony, they will be
collectively called “Environmental Groups”.

2001).

Moore representing Prairie Rivers Network. All of these groups filed post-hearing comments
that will be discussed in detail below. After reviewing the testimony and comments, the Board
finds that it is appropriate to proceed to second notice with this rule.
SUMMARY OF THE PROPOSAL
The proposed amendments add new requirements concerning antidegradation of waters in
the State to the Board’s current rules found at 35 Ill. Adm. Code 302.105. The proposal would
designate the State’s water resources to reflect the three tiers of the federal program. The
proposal also adds procedures for the implementation of the program as a part of the National
Pollutant Discharge Elimination System (NPDES) permit process.
Tier 1 in the federal scheme is based on achieving and maintaining existing stream uses.
Prop. at 3. Tier 1 sets the minimum level of protection and is intended to be the absolute floor of
water quality protection for all waters of the United States.
Id
. Tier 2 of the federal program
addresses waters whose quality exceeds the levels necessary to support the propagation of fish,
shellfish, or wildlife and recreation in and on the water. Water quality cannot be lowered below
the level necessary to protect the “fishable/swimmable” uses and other existing uses. Prop. at 3.
However, maintaining a level of water quality above the “fishable/swimmable” level is not
always required and water quality may be lowered if necessary to accomplish important
economic or social development in the area in which the waters are located.
Id
. and 40 C.F.R.
131.12(a)(2).
Tier 3 of the federal regulations requires that high quality water, which constitutes
outstanding resource waters, must be maintained and protected. Prop. at 4. Examples of
outstanding resource waters could include waters of national and state parks, wildlife refuges or
water of exceptional recreational or ecological significance.
Id
. To reflect Tier 3 in Illinois, the
Board is proposing rules at 35 Ill. Adm. Code 303 creating the category of waters classified as
“outstanding resource waters” or ORWs. The Board also proposes adding a new Subpart to the
Board’s procedural rules at 35 Ill. Adm. Code 102 to regulate the process for classification of
Outstanding Resource Waters.
PROPOSED CHANGES TO THE PROPOSAL
As previously indicated the Board received three comments after the fourth hearing in
this matter. The comments from the Agency, IERG, and the Environmental Groups indicate that
there are areas of agreement for additional changes to the rule. The comments also indicate
some disagreement. The following discussion will delineate the agreed-upon suggested changes
and discuss the areas of disagreement. The discussion will begin with general comments and
proceed to a section by section breakdown of suggested changes and the Board’s response to the
suggested changes. The Board will not specifically discuss suggested changes that are
nonsubstantive, but the Board will accept most of those suggested changes.
General Comments
The Agency indicated in both the prefiled testimony and the final comments that the
Agency generally supports the Board’s proposal. PC 50 at 1; Exh. 38 at 1. However, the
Agency has three areas of concern regarding the Board’s inclusion of the antidegradation

 
3
implementation procedures in Part 302. First the Agency urges the Board to delete the
implementation procedures from Part 302 and move the implementation procedures to Part 309.
The Agency argues that under the organizational pattern set forth in Subtitle C of the Illinois
Administrative Procedure Code, the requirements for permitting are set forth in Part 309. PC 50
at 5. The Agency points out that since the codification of environmental regulations the Board
has followed the practice of centrally locating permit regulation by media, and such a practice
decreases the potential for confusion among the regulated community and facilities in the
permitting process.
Id
. The Agency urges the Board to continue this practice.
Secondly, the Agency indicated that because the Board had included Exhibit B from the
proposal for rulemaking as Section 302.102(f), there were several concerns about the language as
originally included. PC 50 at 2. Specifically, the Agency proposes that subsections
302.105(f)(2)(A)(i), (f)(2)(B) and (f)(2)(C) should be deleted from the rule. PC 50 at 3-4. The
Agency indicates that these subsections address the Agency’s commitment to interact with the
regulated community prior to an application for an NPDES permit being filed.
Id
. The Agency
asserts that the communication itself does not result in a permit, and it is not mandatory upon any
applicant. Therefore, the Agency believes that the subsections should be deleted.
Finally, the Agency is concerned that the inclusion of the implementation procedures
could be problematic for activities requiring a Section 401 of the Clean Water Act water quality
certification (33 U.S.C. § 1341 (Section 401 certification)). PC 50 at 2; Exh. 38 at 2. The
Agency points out that the proposed rule would apply the Section 302.105(f) procedures to
permit applications as well as the review of activities requiring a Section 401 certification. Exh.
38 at 2. In contrast to the NPDES program, the Agency is not the delegated permitting agency
for federal permits but must work with several federal permitting agencies in the Section 401
certification process.
Id
. Because of the need for coordination, the Agency argues that it is
important that the procedures for the Section 401 certification process remain in Agency rules.
Id
. The Agency therefore requests that the reference to Section 401 certification be removed
from Section 302.105(b)(4) and a new subsection (b)(5) be added.
IERG supports the Agency’s suggested changes including new language in Part 309,
deleting several subsections from 302.105(f), and removing references to Section 401
certification. PC 52 at 12. However, the Environmental Groups have concerns regarding the
Agency’s suggested changes. First, the Environmental Groups “oppose any changes being made
to the First Notice Proposal that will cause substantial delay in the final enactment of protective
regulations.” PC 51 at 2. Secondly, the Environmental Groups object to the deletion of
references to the Section 401 certification. The Environmental Groups assert that the Agency’s
suggested change would separate the procedures for conducting antidegradation review for
NPDES permits from the procedures for reviewing Section 401 certifications. PC 51 at 5. The
Environmental Groups argue that there would be no procedures established in this proceeding for
Section 401 certifications. The Environmental Groups argue that the Agency does not point to
any specific potential conflicts between state and federal rules or procedures. Further, the
Environmental Groups assert that they are unaware of any potential conflicts. PC 51 at 5.
Discussion

 
4
The Board appreciates the Agency suggestion that to remain consistent with other Board
regulations the implementation procedures should be placed in Part 309 of the Board’s rules.
However, the Board agrees with the comment of the Environmental Groups that placing the
implementation procedures into Part 309 at this late stage of the rulemaking would lead to an
unnecessary delay for the reasons explained below.
Based on the Agency’s original proposal, which did not include Part 309, the Board has
published the proposed rule in the
Illinois Register
and Part 309 was not included in the Board’s
first-notice publication. Section 5-10 (c) of the Administrative Procedure Act (APA) (5 ILCS
100/5-5
et seq.
) provides, in part, that:
No agency rule is valid or effective against any person or party, nor may it be
invoked by the agency for any purpose, until it has been made available for public
inspection and filed with the Secretary of State as required by this Act. 5 ILCS
100/5-10(c)
The APA sets out specific rulemaking requirements, which include giving at least 45-
days notice of the agency’s intended action in the
Illinois Register
. 5 ILCS 100/5-40(b). The
notice shall include publishing the text of the proposed rule. 5 ILCS 100/5-40(b)(1). The APA’s
language is clear that the text of any proposed amendment must appear in the
Illinois Register
for
first notice prior to the adoption of the rule. Although an agency may make changes in response
to comments received during the first notice (5 ILCS 100/5-40(c)), the Board does not believe
that this extends to opening and amending a new part. Therefore pursuant to the APA, the Board
would be required to publish a first-notice proposal opening Part 309 and amending Part 309 as
suggested by the Agency. In effect because of APA requirements, this action would return the
antidegradation rule to first notice and would result in a substantial delay in promulgating this
new rule. Therefore, the Board will not make the change suggested by the Agency to move the
implementation procedures to Part 309 in this rulemaking.
The Board notes that the Agency recently proposed a new rulemaking (R02-11) to the
Board entitled, Water Quality Triennial Review: Amendments to 35 Ill. Adm. Code 302.208(e)-
(g), 302.504(a), 302.575(d), 303.444, 309.141(h) and Proposed 35 Ill. Adm. Code 301.267,
301.313, 301.413, 304.120, and 309.157. In R02-11, the Agency proposed amendments to both
Parts 309 and 302. Therefore, the Agency could propose that the implementation procedures for
Part 309 be placed in R02-11 without delaying the instant rulemaking which has been before the
Board since August 30, 2000.
The Board has reviewed the Agency’s request that the Clean Water Act (CWA) Section
401 certification language be removed from Section 302.105(b)(4). A Section 401 certification
under the CWA is when an applicant for a federal permit to conduct any activity that results in a
discharge to navigable waters must first obtain a certification from the Agency that the discharge
complies with applicable water quality and effluent standards. The Agency had included the
Section 401 certification provisions in the original proposal to the Board and this inclusion was
not an issue prior to the Board’s proceeding to first notice. The Agency asserts that procedures
for Section 401 certifications should remain in Agency rules and therefore, the references to
Section 401 certifications should be removed. However, the Environmental Groups disagree and
correctly point out that absent this provision there would be no procedures established in this

 
5
proceeding for antidegradation review of Section 401 certifications. The Board believes that a
procedure should be in place to review discharges subject to Section 401 certification for
potential degradation of waters of the State. Therefore, the Board will leave in references to
Section 401 certifications.
 
The Agency has made several specific suggestions for changes to be made in the
language proposed at Section 302.105(f), including a suggestion that portions of Section
302.105(f) be deleted. The Board will make the changes suggested by the Agency where
feasible and incorporate them in Section 302.105(f). The Board notes that one suggestion by the
Agency is to add the phrase “but not limited to” after the word “included” in several places. The
Board will not make that change as the phrase “but not limited to” is redundant because
“included” does not mean the subsequent listing is an exhaustive list.
Section 302.105(b)
IERG states that it assumes the Board did not intend Section 302.105(b)(3)(B) and (C) to
apply only to activities authorized under Section 302.105(b)(1)(A) and (B) and indicates that
IERG has discussed language with the Environmental Groups. IERG also seeks clarification in
the Board’s opinion and order of the Board’s intent concerning Section 302.105(b)(3)(B). IERG
is unsure of the Board’s intent for the requirement “that increases in loading to ORWs improve
water quality.” PC 52 at 11.
The Environmental Groups agree with IERG’s assumption that the Board did not intend
Section 302.105(b)(3)(B) and (C) to apply to activities authorized under Section
302.105(b)(1)(A) and (B) and offers identical language to clarify the rule. In addition, the
Environmental Groups suggest language to clarify that the provisions of Section
302.105(b)(1)(B) allows stormwater discharges in existence when the ORW is designated. PC
51 at 24-25. The Environmental Groups believe that Section 302.105 (b)(1)(B) might be read to
allow degradation of an ORW and also prevent certain loadings that were “probably intended to
be allowed.” PC 51 at 23.
Discussion
In response to IERG’s uncertainty regarding Section 302.105(b)(3)(B), the Board notes
that increases in loading of one constituent that may reduce the loading of one or more
constituents may be an improvement in water quality. Also, adding a new constituent that would
eliminate a bioaccumulative chemical of concern is an additional example of an activity that may
improve water quality. However, this is not an exhaustive list and the Board does not intend that
it should be.
Regarding IERG’s comments pertaining to the intent of Section 302.105(b)(3)(B) and
(C), the Board notes that IERG correctly assumes that the increase in pollutant loadings to an
ORW is not limited to the activities listed in Section 302.105(b)(1). Subsection
302.105(b)(3)(B) allows for an increase in pollutant loading under a very limited circumstance
where such an increase is necessary for an activity that will improve the quality of the ORW.
The Board does not consider an increase in pollutant loading pursuant to subsection
302.105(b)(3)(B) as lowering the quality of an ORW. In this regard, the Board notes that the

 
6
proposed regulations prohibit the lowering of quality of an ORW, except for the activities listed
in Section 302.105(b)(1). The Board declines to make the change to Section 302.105(b)(3)
suggested by IERG and the Environmental Groups. Furthermore, the Board declines to make the
suggested change to Section 302.105(b)(1)(B) regarding stormwater discharges to an ORW
offered by the Environmental Groups. The Board believes the rule as written very clearly
reflects that only stormwater discharges in existence on the day an ORW is designated are
allowed if such discharges are in compliance with applicable stormwater discharge and water
quality regulations. The Board believes that adopting the Environmental Groups’ proposed
language would narrow the scope of the exception by limiting the applicability to only
discharges that require an NPDES permit or Section 401 certification.
 
Section 302.105(c)(2)
The Agency suggests that a new sentence be added Section 302.105(c)(2) and Section
302.105(f)(2) that indicates that the Agency will make antidegradation assessments on a case-by-
case basis. PC 50 at 7. The Agency makes this request in response to IERG’s testimony at the
August 24, 2001 hearing. The Agency states that the Environmental Groups and IERG met and
agree that this concept should be included in the rule.
IERG agrees that this language should be added and further suggests that Section
302.105(c)(2)(B) be amended to reflect that the Agency’s decision will be made on a case-by-
case basis. PC 52 at 3-4. IERG also suggests that the language be clarified in this section to
clearly identify to the regulated community when an antidegradation review is triggered. PC 52
at 8. Although IERG had initially suggested language, IERG had subsequent discussions with
the Agency, which has led to IERG’s suggestion in this comment.
Id
. IERG wishes to explicitly
state “that which is implicit in the Board’s proposal” that for constituents for which a limit is
expressly stated in a permit, the antidegradation process is triggered by an applicant’s request
that would exceed that permit limit. PC 52 at 8-9. IERG would ask that the same language be
added in Section 302.105(f).
The Environmental Groups indicate that they do not object to the inclusion of the case-
by-case language proposed by the Agency. PC 51 at 6. The Environmental Groups also do not
object to the language proposed by IERG; however, the Environmental Groups believe such
language is repetitive. PC 51 at 7.
Discussion
The Board notes that all permit decisions made by the Agency are based on the specifics
of the permit application, utilizing both the Agency’s rules and the Board’s rules. As there
appears to be no objection to the inclusion of this language the Board will make the suggested
change in Section 302.105(c)(2). However, the Board agrees that the further inclusion of the
language in subsection (c)(2)(B) is repetitive and the Board will not make that change.
The Board declines to amend Section 302.105(c)(2) and (f)(1) to add the language
suggested by IERG. The Board believes that the language in these subsections is clear on its
face.
Section 302.105(c)(2)(C)

 
7
IERG indicates that it has reconsidered its request to include a
de minimis
exception in
the rule. PC 52 at 7. However, IERG suggests that the Board add to Section 302.105(c)(2)(C) a
new subsection to allow the Agency to consider a
de minimis
demonstration as one of its sources
of information in making an antidegradation assessment.
Id
. IERG would have the applicant
prepare the demonstration and the demonstration would show that the increased loading of a
pollutant (other than a bioaccumulative chemical of concern) does not utilize more than 10% of
the assimilative capacity of the receiving waters.
Id
.
Discussion
In the Board’s first-notice opinion and order, the Board addressed the issue of a
de
minimis
exception at length. The Board stated that:
The Board notes that since the proposed exception does not make any distinctions
based on the nature and characteristics of the discharge, IERG’s proposal would
allow discharge of bioaccumulative and persistent chemicals without an Agency
review as long as the increased level is below the
de minimis
level. Discharge of
even small amounts of such chemicals may not be advisable in certain water
bodies. Further, the Board agrees with the Agency that the actual determination
of the assimilative capacity of receiving water body may take as much effort as
performing the antidegradation review. Revision to Antidegradation Rules: 35
Ill. Adm. Code 302.105, 303.205, 303.206, And 102.800-102.830 R01-13 (June
21, 2001)
slip. op.
at 16.
 
Although IERG has modified it’s request for a
de minimis
exception, the Board believes that the
Board’s decision to not include a
de minimis
exception in these rules is appropriate for Illinois.
Therefore, the Board will stand by the discussion in the first-notice opinion.
 
Section 302.105(d)(5)
During the August 24, 2001 hearing, IERG made a suggestion regarding non-contact
cooling water, and there was extensive discussion on the record at the hearing regarding non-
contact cooling water. Tr. 8/24/01 at 12, 25-30. The Agency agreed to review the language after
the hearing and has proposed a change. The Agency noted that the additive discussed is chlorine
and the suggested change would present minimal environmental impact, due to the technical
reliability of de-chlorination processes. Further the Agency believes the suggested language
change would provide a benefit to the regulated community. PC 50 at 8.
IERG concurs with the Agency’s suggested language. IERG indicates that the regulated
community and the Agency “have come to understand that application of this exception to non-
contact cooling water containing only the additive chlorine, and where dechlorination occurs
before discharge is an acceptable compromise.” PC 52 at 6.
The Environmental Groups oppose the suggested language change. Specifically, they
argue that the record does not contain enough information to determine that chlorine is removed
by processing to the extent that chlorine never poses a danger to aquatic life. PC 51 at 7. The

 
8
Environmental Groups further argue that the lack of an exemption for chlorine would impose
little hardship due to the case-by-case approach proposed to the Board. PC 51 at 8.
Discussion
The Board appreciates the concerns expressed by the Environmental Groups. However,
the language agreed to by IERG and the Agency would require the removal of chlorine and the
maintenance of an effluent limit. The Board feels these safeguards will ensure that there is no
environmental harm and the Board will therefore accept the language change.
Section 302.105(d)(6)
The Agency indicates that the Section 401 certification process does not use the phrase
“general” Section 401 certification. PC 50 at 9. To avoid potential confusion, the Agency
suggests that this subsection be amended to replace the phrase “general CWA, Section 401
certification” with “for nationwide or regional Section 404 of the CWA permit.” PC 50 at 9.
The Agency stated that IERG and the Environmental Groups also suggest the language be
clarified to better reflect the certification process when an activity is subject to a nationwide
permit.
Id
.
In addition to the Agency’s suggestion in this subsection, IERG suggests that the
language “waters of particular biological significance” be deleted. IERG argues that the Board
does not discuss this phrase in the opinion and IERG is uncertain what the Board means by the
term. PC 52 at 13. IERG asks if the Board intended to use “Outstanding Resource Waters” in
this subsection.
IERG notes that the Environmental Groups endorse the use of “waters of particular
biological significance” and the Environmental Groups suggest that the Agency rely on the 1991
report prepared by the Illinois Department of Conservation
3
titled “Biologically Significant
Illinois Streams” to determine what constitutes “waters of particular biological significance.” PC
52 at 14. IERG objects to relying on the 1991 publication. PC 51 at 14. IERG asserts that the
Environmental Groups have not filed evidence of the methodology used to identify waters in the
1991 publication and the authors do not explain what data was relied on. Further the data in the
1991 publication is out of date and the 1991 publication indicates that some of the water bodies
identified cannot be saved. PC 51 at 15-16.
The Environmental Groups suggest clarifying “waters of particular biological
significance” by deleting the phrase and replacing it with:
which include waters identified by the Illinois Department of Natural Resources
to be biologically significant, waters known to contain state or federally listed
threatened or endangered species, or water identified as having high levels of
biodiversity. PC 51 at 26
Discussion

One of the agencies combined to form the Illinois Department of Natural Resources.

 
9
The Board will make the change suggested by the Agency and agreed to by IERG and the
Environmental Groups by replacing “general CWA, Section 401 certification” with “for
nationwide or regional Section 404 of the CWA permit.” With regard to the phrase “waters of
particular biological significance” the Board will add a reference to the Illinois Department of
Conservation publication entitled “Biologically Significant Illinois Streams.” The Board will not
make this publication the definitive source but rather list it as a possible listing of waters of
particular biological significance.
 
Section 302.105(f)(1)(G)
The Environmental Groups have suggested that the Board’s regulations should make
clear that the Illinois Department of Natural Resources should be notified of proposals to allow
new or increased pollution to Illinois waters. PC 51 at 26. The Environmental Groups assert
that DNR has broad responsibilities under DNR’s general powers and under the Illinois
Endangered Species Act to protect Illinois aquatic life.
Id
.
IERG opposes the language suggested by the Environmental Groups. PC 52 at 21-22.
IERG argues that the General Assembly has given authority to specified agencies to administer
environmental programs.
Id
. IERG maintains that only the General Assembly can give DNR a
role in administering the antidegradation regulations in Illinois, and since the General Assembly
has not done so, IERG opposes the Board entitling DNR to have such involvement.
Id
.
Discussion
The Board agrees with IERG that only the General Assembly may give DNR the
authority to administer any part of the antidegradation regulations in Illinois. However, the
Board notes that any one may comment on draft NPDES permits and that would include DNR.
The Board further notes that under the proposal, as DNR does in all rulemaking proceedings,
DNR will be notified of a petition for outstanding resource water (ORW) designation.
Therefore, the Board believes that providing DNR notice of a permit application would not be
beyond the Board’s authority and the Board will amend the proposal to provide that DNR
receive notice of permit applications.
Part 102
IERG expresses concerns about the Board’s amendments to Part 102. First, IERG feels
that the notice requirements of Part 102 are insufficient to notify all prospective landowners and
interested parties. Secondly, IERG maintains that proponents of an ORW designation should
have an obligation to support and petition for ORW designation and the requirements of Part 102
do not sufficiently provide for such proof.
Regarding notification, IERG points out that the Board requires newspaper publication of
petitions for adjusted standards (35 Ill. Adm. Code 104.408) and newspaper notice and additional
written notice for petitions for variances (35 Ill. Adm. Code 214(a), (b)). IERG reiterates the
testimony of Toby Frevert from the November 17, 2000 hearing in which he indicated that the
ramifications of a decision to designate an ORW are more significant than those of an adjusted
standard or variance. Tr. 11/17/00 at 88; PC 52 at 18. IERG quotes testimony from Mr. Frevert
that indicates the willingness of the Agency to assist in notification of potentially interested

 
10
parties. PC 52 at 19, citing Tr. 8/24/01 at 15-20. IERG states that it is “unequivocally convinced
that its proposed expanded notification requirements are justified and strongly urges the Board to
adopt the necessary notification requirements.” PC 52 at 18.
IERG also believes that additional language should be added to the Part 102 proposed
amendments that would require a proponent of an ORW designation to submit supporting
documentation to prove the designation is warranted. PC 52 at 19. IERG maintains that a
proponent of an ORW designation, modification or repeal “has an obligation to offer sufficient
evidence in support of its position to allow the Board to meaningfully consider” the statutory
factors in Section 27 of the Act (415 ILCS 5/27 (2000)). PC 52 at 20. IERG argues that any
proponent in a regulatory proceeding before the Board has a minimum burden in moving a
proposal forward.
Id
. Therefore, IERG suggests that the Board amend its proposal for Part 102
to reflect these ideas.
The Agency did not comment on this specific proposal by IERG. However, the
Environmental Groups oppose the suggestions. The Environmental Groups believe that the
Board’s proposal sets forth sufficient notice requirements and the Agency’s testimony
concerning the Agency’s willingness to assist in notification supports the Board’s decision. PC
51 at 15. The Environmental Groups also believe that newspaper notice is not necessary. PC 51
at 16.
The Environmental Groups maintain that the scope and burden of the petition for ORW
designation must be kept to a reasonable level or the opportunity to petition for a designation will
be frustrated. PC 51 at 16. The Environmental Groups agree that the record before the Board
must demonstrate compliance with the Board regulations; however, placing the burden on the
proponent should be rejected. PC 51 at 16-17.
The Environmental Groups also made a specific request that the language at Section
102.830(b)(2) be amended. The Environmental Groups suggest deleting the phrase “uniquely
high biological or recreational quality” and using the phrase “exceptional recreational or
ecological significance”. PC 51, Attachment 1 at 3; Tr. 8/24/01 at 63-64. The Environmental
Groups argue that this language is more appropriate as it reflects the federal language found at 40
C.F.R. 131.12(a)(3).
Discussion
First the Board will address the concern of IERG that the proposal does not require a
minimum burden of going forward with the proposal and that the requirements of Part 102 do not
require sufficient support of the petition. The Board notes that in its first-notice opinion and
order the Board addressed IERG’s concern about a “burden of proof”. The Board stated:
The Board does not agree with IERG’s position that a “burden of proof” must be
established in the ORW designation process. The Board’s rulemaking
proceedings allow for testimony, cross-questioning of testifiers, and comments
from any person or group as long as the testimony is relevant and not repetitious.
35 Ill. Adm. Code 102.426 and 102.430. The proponent of a rule must present
testimony in support of that rule. 35 Ill. Adm. Code 102.428. Thus, the

 
11
rulemaking process will allow for development of the most complete record
possible, allowing ample opportunities for those in support or opposition to
present opinions to the Board on the designation of an ORW. The Board can then
weigh all the information and evidence in the record and determine if the
designation of an ORW is warranted. Furthermore, this same rulemaking process
will be available to repeal an ORW designation should circumstances change
concerning that body of water. Revision to Antidegradation Rules: 35 Ill. Adm.
Code 302.105, 303.205, 303.206, and 102.800-102.830 R01-13
(June 21, 2001)
slip. op.
at 22.
The Board is convinced that the position articulated regarding burden of proof at first notice is
just as relevant to IERG’s concerns expressed in this opinion. Furthermore, the proposal at
Section 102.830 specifies when a petition might be dismissed and when the Board will grant
ORW status. Thus, the Board finds that the burden of a proponent in a petition for ORW
designation, modification or repeal need not be further articulated and the Board declines to add
additional language to the proposal.
IERG has also suggested that the Board require the proponent to notify many different
individuals and groups and to provide newspaper notification of the petition. The Board believes
that the rulemaking process affords ample notice of an action and additional notice by the
petitioner is not warranted. IERG suggests that since newspaper publication is required of
variances and adjusted standards it should be required for ORW petitions. However, under
Section 27 of the Act a hearing is required in a rulemaking whereas a hearing is not required in
either an adjusted standard or variance. Further, the Board’s rules require notice of the
rulemaking hearing be published in the area affected. See 35 Ill. Adm. Code 102.416. Thus,
newspaper notice of the petition will be given by the Board indicating that a hearing has been
scheduled.
The Board is cognizant of IERG’s concerns that landowners that may be affected be
notified. The Agency has indicated it will assist in notifying potentially affected persons. To
ensure that notification occurs, the Board will commit to including all potentially affected
persons on the notice list of the rulemaking upon acceptance of the petition. The Board will ask
the Agency to provide information such as the names of NPDES permit holders and applicants
along the proposed water body or water body segment. The Board will send copies of Board
opinion and orders to those persons on the notice list. The Board need not make a change to the
rule to reflect this policy.
The Board will adopt the proposed change offered by the Environmental Groups to
Section 102.830(b)(2) by deleting “uniquely high biological or recreational quality” and inserting
“exceptional recreational or ecological significance”. In order to ensure that the rule is
consistent, the Board will also make this change in Section 303.205.
ECONOMIC REASONABLENESS AND TECHNICAL FEASIBILITY
As indicated in the Board’s first-notice opinion and order, the Agency’s proposal
addressed the economic reasonableness and technical feasibility of the proposal. The Agency
indicated that the proposal is a revision of the existing State water quality standard. Prop. at 6.

 
 
12
The Agency maintains that the revision updates and clarifies existing policy and is expected to
lessen the economic burden on the regulated community by listing activities that are already
considered in compliance with the requirements without the need for an individual
antidegradation review.
Id
. The Agency also asserts that the standard establishes criteria, which
will provide better guidance for determining compliance with the antidegradation standard.
Id
.
On June 25, 2001, pursuant to Section 27(b) of the Act, the Board requested that the
Department of Commerce and Community Affairs (DCCA) conduct an economic impact study
on the proposed rule. On March 10, 2000, DCCA had informed the Board that it would not be
doing economic impact studies. At the August 24, 2001 hearing the Board provided copies of
the DCCA letter and the Board’s June 25, 2001 letter. The Board received no comments on the
letter.
In this proceeding the Board has received 52 public comments and held four hearings.
The only issue of economic concern has been the impact of declaring a water and Outstanding
Resource Water. As the Board will be using rulemaking procedures for those designations, the
economic impact of such a designation will be examined with each proposal. The remaining
evidence in this record indicates that the rule is economically feasible and technically reasonable
and the Board so finds.
CONCLUSION
The Board today proceeds to second notice with the proposal. The Board finds that the
proposal is economically reasonable and technically feasible. The second notice proposal will
include changes suggested by the participants to clarify the rule.
ORDER
The Board directs that the following rule be submitted to the Joint Committee on
Administrative Rules for second notice.

SUBPART A: GENERAL WATER QUALITY PROVISIONS
 
Section 302.105 Antidegradation
 
The purpose of this Section is to protect existing uses of all waters of the State of Illinois,
maintain the quality of waters with quality that is better than water quality standards, and prevent
unnecessary deterioration of waters of the State.
 
a) Existing Uses
 
Uses actually attained in the a surface water body or water body segment on or after
November 28, 1975,
 
whether or not they are included in the water quality standards, must

 
19
be maintained and protected. Examples of degradation of existing uses of the waters of
the State include:
 
1) an action that would result in the deterioration of the existing aquatic
community, such as a shift from a community of predominantly pollutant-
sensitive species to pollutant-tolerant species or a loss of species diversity;
 
2) an action that would result in a loss of a resident or indigenous species
whose presence is necessary to sustain commercial or recreational
activities; or
 
3) an action that would preclude continued use of a surface water body or
water body segment for a public water supply or for recreational or
commercial fishing, swimming, paddling or boating.
b) Outstanding Resource Waters
1)
Waters that are designated as Outstanding Resource Waters (ORWs)
pursuant to 35 Ill. Adm. Code 303.205 and listed in 35 Ill. Adm. Code
303.206 must not be lowered in quality except as provided below:
 
A) Activities that result in short-term, temporary (i.e., weeks or
months) lowering of water quality in an ORW; or
 
B) Existing site stormwater discharges that comply with applicable
federal and State state stormwater management regulations and do
not result in a violation of any water quality standards.
 
2) Any activity in subsections (b)(1)(A) or (b)(1)(B) that requires a National
Pollutant Discharge Elimination System (NPDES) or a Clean Water Act
(CWA) Section 401 certification must also comply with subsection (c)(2).
 
3) Any activity listed in subsection (b)(1) or proposed increase in pollutant
loading must also meet the following requirements:
 
A) All existing uses of the water will be fully protected;
 
B) The proposed increase in pollutant loading is necessary for an
activity that will improve water quality in the ORW; and
 
C) The improvement could not be practicably achieved without the
proposed increase in pollutant loading.
 
4) Any proposed increase in pollutant loading requiring an NPDES permit or
a CWA 401 certification for an ORW must be assessed pursuant to
subsection (f) to determine compliance with this Section.
 
c) High Quality Waters

 
20
 
1) Except as otherwise provided in subsection (d) of this Section, waters of
the State whose existing quality is better than any of the established
standards of this Part must be maintained in their present high quality,
unless the lowering of water quality is necessary to accommodate
important economic or social development.
 
2) The Agency must assess any proposed increase in pollutant loading that
necessitates a new, renewed or modified NPDES permit or any activity
requiring a CWA Section 401 certification to determine compliance with
this Section 302.105. The assessment to determine compliance with
Section 302.105 must be made on a case-by-case basis. In making this
assessment, the Agency must:
 
A) Consider the fate and effect of any parameters proposed for an
increased pollutant loading; and
 
B) Assure the following:
 
i) The applicable numeric or narrative water quality standard
will not be exceeded as a result of the proposed activity;
 
ii) All existing uses will be fully protected;
 
iii) All technically and economically reasonable measures to
avoid or minimize the extent of the proposed increase in
pollutant loading have been incorporated into the proposed
activity; and
 
iv) The activity that results in an increased pollutant loading
will benefit the community at large.
 
C) Utilize the following information sources, when available:
 
i) Information, data or reports available to the Agency from
its own sources;
 
ii) Information, data or reports supplied by the applicant;
 
iii) Agency experience with factually similar permitting
scenarios; or
 
iv) Any other valid information available to the Agency.
 
d) Activities Not Subject to a Further Antidegradation Assessment
 

 
21
The following activities will not be subject to a further antidegradation assessment
pursuant to subsection (c) of this Section.
 
1) Short-term, temporary (i.e., weeks or months) lowering of water quality;
 
2) Bypasses that are not prohibited at 40 CFR 122.41(m);
 
3) Response actions pursuant to the Comprehensive Environmental
Response, Compensation and Liability Act (CERCLA), as amended,
corrective actions pursuant to the Resource Conservation and Recovery
Act (RCRA), as amended or similar federal or State authority, taken to
alleviate a release into the environment of hazardous substances,
pollutants or contaminants which may pose a danger to public health or
welfare;
 
4) Thermal discharges that have been approved through a CWA Section
316(a) demonstration;
 
5) New or increased discharges of a non-contact cooling water:
 
A
without additives, except as provided in subsection (d)(5)(B)
returned to the same body of water from which it was taken, as
defined by 35 Ill. Adm. Code 352.104, provided that the discharge
complies with applicable Illinois thermal standards; or
 
B containing chlorine when the non-contact cooling water is treated to
remove residual chlorine, and returned to the same body of water
from which it was taken, as defined in 35 Ill. Adm. Code 352.104,
provided that the discharge complies with applicable Illinois
thermal and effluent standards at 35 Ill. Adm. Code 302, 303, and
304.
 
6) Discharges permitted under a current general NPDES permit as provided
by 415 ILCS 5/39(b)
 
or a general CWA, Section 401 certification
nationwide or regional Section 404 of the CWA permit are not subject to
facility-specific antidegradation review; however, the Agency must assure
that individual permits or certifications are required prior to all new
pollutant loadings or hydrological modifications that necessitate a new,
renewed or modified NPDES permit or CWA, Section 401 certification
that affects waters of particular biological significance. Waters of
particular biological significance may include streams listed in a 1991
publication by the Illinois Department of Conservation entitled
“Biologically Significant Illinois Streams; or
 
7)
Changes to or inclusion of a new permit limitation that does not result in
an actual increase of a pollutant loading, such as those stemming from

 
22
improved monitoring data, new analytical testing methods, new or revised
technology or water quality based effluent limits.
 
e) Lake Michigan Basin
 
Waters in the Lake Michigan basin as identified in 35 Ill. Adm. Code 303.443 are also
subject to the requirements applicable to bioaccumulative chemicals of concern found at
Section 302.521 of this Part.
 
f) Antidegradation Assessments
 
In conducting an antidegradation assessment pursuant to this Section, the Agency must
comply with the following procedures.
 
1) A permit application for any proposed increase in pollutant loading that
necessitates the issuance of a new, renewed, or modified NPDES permit,
with a new or increased permit limit, or a CWA Section 401 certification,
must include, to the extent necessary for the Agency to determine that the
permit application meets the requirements of Section 302.105, the
following information:
 
A) Identification and characterization of the water body affected by
the proposed load increase or proposed activity and their the
existing water body’s uses. Characterization must address
physical, biological and chemical conditions of the water body;
 
B) Identification and quantification of the proposed load increases for
the applicable parameters and of the potential impacts of the
proposed activity on the affected waters;
 
C) The purpose and anticipated benefits of the proposed activity. Such
benefits may include:
 
i) Providing a centralized wastewater collection and treatment
system for a previously unsewered community;
 
ii) Expansion to provide service for anticipated residential or
industrial growth consistent with a community’s long range
urban planning;
 
iii) Addition of a new product line or production increase or
modification at an industrial facility; or,
 
iv) An increase or the retention of current employment levels
at a facility.
 

 
23
D) Assessments of alternatives to proposed increases in pollutant
loading or activities subject to Agency certification pursuant to
Section 401 of the CWA that result in less of a load increase, no
load increase or minimal environmental degradation. Such
alternatives may include:
 
i) Additional treatment levels, including no discharge
alternatives;
 
ii) Discharge of waste to alternate locations, including
publicly-owned treatment works and streams with greater
assimilative capacity; or
 
iii) Manufacturing practices that incorporate pollution
prevention techniques.
 
E) Any additional information the Agency may request.
 
F)
Proof that a copy of the application has been provided to the
Illinois Department of Natural Resources.Any of the information
sources identified in subsection 302.105(d) (3).
 
2) The Agency must complete an antidegradation demonstration assessment
review in accordance with the provisions of this Section on a case-by-case
basis.
 
  
A)
The Agency must consider the criteria stated in Section
302.105(c)(2);The antidegradation assessment pursuant to this
Section is a part of the NPDES permitting process or the CWA
Section 401 certification process. However, applicants may
initiate communication with the Agency, preferably during the
planning stage for any load increase. Communication will help
assure the adequacy of information necessary to constitute an
antidegradation demonstration and avoid or minimize delays and
requests for supplemental information during the permitting stage.
The Agency review process must be initiated by:
