 1                     HEARING OFFICER GLENN:  Good morning.  My 
  
 2        name is Cathy Glenn, and I have been appointed by the 
  
 3        Board to serve as hearing officer in this proceeding 
  
 4        entitled, In the Matter of Proposed Amendments to 
  
 5        Ammonia Nitrogen Standards 35 Illinois Administrative 
  
 6        Code 302.212, 302.213 and 304.122, Docket Number 
  
 7        R02-019. 
  
 8                     Seated to my right is Dr. Ronald Flemal, 
  
 9        the lead board member assigned to this matter.  To 
  
10        Dr. Flemal's right is Board Member Michael Tristano. 
  
11        And to my left is Dr. Tanner Girard, and to his left is 
  
12        Anand Rao.  Dr. Girard and Member Tristano are also 
  
13        assigned to this rule making today. 
  
14                     Also in the back of the room, staff with 
  
15        the Board are Alecia Liu of the Board's technical unit, 
  
16        and Erin Conley who is the board's rule making 
  
17        coordinator. 
  
18                     Today's hearing will begin with a 
  
19        presentation of testimony and comments that were not 
  
20        presented at the first hearing.  After the testimony of 
   
21        each, we will allow that questions be asked of the 
  
22        witnesses, and we will also have the witnesses read 
  
23        their testimony into the record because it is short 
  
24        testimony. 
  
  
  
  
  
  
  
                                                               3

 1                     Anyone may ask a question after the 
  
 2        witnesses have testified.  I do ask that if you have a 
  
 3        question, that you raise your hand, wait for me to 
  
 4        recognize you and please state your name and what group 
  
 5        you are with. 
  
 6                     Speak clearly please for the benefit of the 
  
 7        court reporter, and if you could speak loudly, she would 
  
 8        appreciate that also.  If we can't hear you, we will ask 
  
 9        you to speak up.  Please note that any question that 
  
10        might be asked by any of the Board's board members or 
  
11        board staff are intended to help build a complete record 
  
12        in this matter and are not meant to express any 
  
13        preconceived notion or bias. 
  
14                     In addition to the prefiled testimony 
   
15        today, we will allow anyone else who wishes to testify 
  
16        the opportunity to do so.  And I have placed at the side 
  
17        of the room a sign-up sheet if indeed you do wish to 
  
18        testify.  Also at the side of the room on the table, 
  
19        there are the most recent copies of the Board's notice 
  
20        list and service list in this matter.  If you wish to 
  
21        receive copies of the Board's opinions and orders and 
  
22        hearing officer orders, you may sign up for the notice 
  
23        list.  If you would like to receive copies of those 
  
24        items as well as anything else that is filed with the 
  
  
  
  
  
  
  
                                                               4 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        Board in this matter, you may sign up to be on the 
  
 2        Board's service list. 
  
 3                     Prior to filing any further documents in 
  
 4        this case, if you intend to file anything, please call 
  
 5        me or the clerk's office in Chicago so that we may get 
  
 6        you the most recent copy of the service list.  And I 
  
 7        think that is all we had. 
   
 8                     Did anyone have any questions before we get 
  
 9        started?  Can you all hear me okay?  Okay, wonderful. 
  
10                     At this time, I would ask Dr. Flemal if he 
  
11        wishes to say anything. 
  
12                     BOARD MEMBER FLEMAL:  On behalf of the 
  
13        Board, I'd like to, again, to invite you -- it's my 
  
14        appreciation to invite you to join in with us on the 
  
15        proceeding that we're here for. 
  
16                     At the last session, I ran through what the 
  
17        Board's procedure is as we develop the record and 
  
18        ultimately go to a decision on this proposal.  I won't, 
  
19        since most of the faces here are familiar, go through 
  
20        that whole series of events again, but let me just note 
  
21        for the people who are perhaps coming here for the first 
  
22        time, that once the Board develops this record 
  
23        completely, and we should do that with the completion of 
  
24        a post-hearing comment period, the Board will deliberate 
  
  
  
  
  
  
  
                                                               5 
                            KEEFE REPORTING COMPANY 
   
  
 
 1        collectively on the proposal before us and decide what 
  
 2        the disposition of the proposal will be.  We would hope 
  
 3        that will be in a relatively short time following the 
  
 4        closing of today's activities. 
  
 5                     HEARING OFFICER GLENN:  Thank you, 
  
 6        Dr. Flemal. 
  
 7                     Would anyone else like to say anything? 
  
 8        Dr. Girard or Mr. Tristano? 
  
 9                     DR. GIRARD:  Just good morning. 
  
10                     HEARING OFFICER GLENN:  All right.  With 
  
11        that, let's get started.  Mr. Kissel? 
  
12                     MR. KISSEL:  We have two witnesses today. 
  
13        You have the prefile testimony of them. 
  
14                     We have also filed a revised proposed rule, 
  
15        and my suggestion is that we make that an exhibit to 
  
16        this proceeding at this time. 
  
17                     HEARING OFFICER GLENN:  Let's make that an 
  
18        exhibit.  If there are no objections, I would like to 
  
19        admit at this time the IAWA's proposed rule, which 
  
20        includes corrected appendices from last Friday.  They 
  
21        should have served all of you on the service list with a 
   
22        copy of the two append -- appendixes, I believe, (c)(2) 
  
23        and (c)(3).  I think that's correct. 
  
24                     So we will admit at this time, if there are 
  
  
  
  
  
  
  
                                                               6 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        no objections, as Exhibit Number 10, the amended 
  
 2        proposal. 
  
 3                          [Whereupon Exhibit Number 10 was 
  
 4                          marked for identification and admitted 
  
 5                          into evidence.] 
  
 6                     MR. KISSEL:  For the record, that proposal 
  
 7        was filed with the Board on April 3, 2002 with the 
  
 8        notice of filing. 
  
 9                     HEARING OFFICER GLENN:  Thank you. 
  
10                     MR. KISSEL:  That's Exhibit Number 10; is 
  
11        that right? 
  
12                     HEARING OFFICER GLENN:  That's correct. 
  
13                     MR. HARSCH:  Roy Harsch.  I'll briefly 
  
14        explain the principal changes in the amended proposal. 
  
15                     That following up on some suggestions from 
   
16        the Board, we added the word "water" when referencing 
  
17        temperature, or in a number of places, following the 
  
18        suggestion that we were defining summer and winter 
  
19        differently than commonly understood.  We used the early 
  
20        life stage present to refer to summer in a number of 
  
21        places throughout the rule. 
  
22                     Following up on a comment from Mr. Mosher, 
  
23        in 302.212 (c)(3), we talked about the sub-chronic 
  
24        standard being evaluated over a four consecutive day 
  
  
  
  
  
  
  
                                                               7 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        period.  And those are the principal changes. 
  
 2                     HEARING OFFICER GLENN:  Thank you, 
  
 3        Mr. Harsch. 
  
 4                     MR. KISSEL:  We have two witnesses.  I 
  
 5        think the first will be Mr. Callahan.  They have been 
  
 6        previously sworn. 
  
 7                     HEARING OFFICER GLENN:  They have? 
  
 8                     MR. KISSEL:  Yes. 
  
 9                     HEARING OFFICER GLENN:  Wonderful. 
   
10                     MR. KISSEL:  You understand, Mr. Callahan, 
  
11        you're still under oath? 
  
12                     MR. CALLAHAN:  I believe I understand 
  
13        that. 
  
14                     HEARING OFFICER GLENN:  Thank you. 
  
15                     MR. CALLAHAN:  Good morning.  I'd like to 
  
16        read from my prepared testimony, which is prefiled, and 
  
17        then I have a page or two of follow-up that I'd like to 
  
18        expand. 
  
19                     My name is Michael Callahan.  I previously 
  
20        filed testimony on behalf of the Illinois Association of 
  
21        Wastewater Agencies, IAWA, to explain the proposed rule 
  
22        making.  I am here on behalf of the IAWA to explain the 
  
23        revisions that were made to the proposed rule, which 
  
24        were filed on April 2, 2002. 
  
  
  
  
  
  
  
                                                               8 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                     The proposed rule was revised to include 
  
 2        all of the suggested revisions specified in the prior 
  
 3        testimony of Robert Mosher on behalf of the Illinois 
   
 4        Environmental Protection Agency, which was presented at 
  
 5        the first hearing. 
  
 6                     In addition, the revised proposed rule 
  
 7        changed several provisions to address certain comments 
  
 8        by Board Member Flemal put forth at the first hearing in 
  
 9        this matter.  The suggestions included revising the 
  
10        terms "summer" and "winter."  These terms were changed 
  
11        to "early life stage present" and "early life stage 
  
12        absent," which correspond with the time periods intended 
  
13        to be covered with the prior terms.  See section 
  
14        302.212(b)(2) and (e).  No changes to the time periods 
  
15        have been made. 
  
16                     In addition, IAWA added a definition of 
  
17        "early life stage," which is taken from the ORSANCO 
  
18        rule.  This change is consistent with the analysis IAWA 
  
19        undertook in preparation for this rule making. 
  
20        Dr. Robert Sheehan will address this change in further 
  
21        detail. 
  
22                     IAWA also made other minor changes for the 
  
23        purpose of clarification.  IAWA added the word "water" 
  
24        before temperature throughout the rule, and clarified 
   
  
  
  
  
  
  
                                                               9

 1        Section 302.212 (c)(3) to address the sampling required 
  
 2        to evaluate attainment. 
  
 3                     Okay.  And it would be at this time that 
  
 4        I'd like to expand on my testimony a little bit, if I 
  
 5        may. 
  
 6                     I'd like to address a situation in this 
  
 7        proceeding which has developed since the first hearing. 
  
 8        On April 12, 2002, post-hearing comments on Board Docket 
  
 9        R02-19 Triennial Review were filed with the Board by 
  
10        Mr. Albert Ettinger, who is thereby representing the 
  
11        Environmental Law and Policy Center, Prairie Rivers 
  
12        Network and the Sierra Club. 
  
13                     Mr. Ettinger's comments were in response to 
  
14        the lack of implementation rules filed by the Illinois 
  
15        Environmental Protection Agency in docket R02-11.  In 
  
16        his comments, Mr. Ettinger referred to my testimony in 
  
17        these proceedings and referenced a bitterness or 
  
18        acrimony associated with the IAWA's approach in 
   
19        advocating the ammonia water quality standard we are 
  
20        discussing today.  Further, Mr. Ettinger alleges that 
  
21        this bitterness was in response to the fact that IAWA 
  
22        came away from the RA-94 proceedings without a likely 
  
23        understanding of what the implementation rules were 
  
24        going to be for -- of the effluent modified water 
  
  
  
  
  
  
  
                                                               10 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        concept.  I reference page three of his filing in that 
  
 2        regard. 
  
 3                     I believe that a terrible misunderstanding 
  
 4        of the IAWA's position with regard to both RA-94 and 
  
 5        these proceedings exists, and I would like to clear the 
  
 6        record of this misunderstanding at this time. 
  
 7                     This misunderstanding lies in the fact that 
  
 8        the exact opposite of Mr. Ettinger's allegations in his 
  
 9        April 12, 2002 comments occurred regarding 
  
10        implementation rules.  Further, any bitterness detected 
  
11        on behalf of IAWA or me is certainly not directed 
   
12        towards the Board or the Agency. 
  
13                     Let me explain.  As I indicated in my 
  
14        testimony during the first hearing, the primary tenet 
  
15        regarding the ammonia water quality standard and the EMW 
  
16        concept, developed as a result of R94-1, was that there 
  
17        existed no impairment of aquatic life statewide 
  
18        attributable to ammonia nitrogen below NPDES outfalls, 
  
19        that they were complying with monthly average ammonia 
  
20        limits of 1.5 milligrams per liter, summer, and 4.0 
  
21        milligrams per liter, winter. 
  
22                     Consequently, dischargers located on 
  
23        receiving streams, where pH and water temperature 
  
24        conditions would require monthly average ammonia permit 
  
  
  
  
  
  
  
                                                               11 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        limits less than 1.5 milligrams per liter summer and 4.0 
  
 2        milligrams per liter winter, would receive permits, 
  
 3        permit limits equal to those two values.  The duration 
  
 4        of the receiving stream below such a permitted outfall 
   
 5        would be classified as EMW until the ammonia water 
  
 6        quality standard was obtained through the natural 
  
 7        ammonia assimilation capability of the stream itself. 
  
 8                     This was the interpretation of the R94-1 
  
 9        rule making by IAWA.  I believe that this is also the 
  
10        understanding of the Agency, in as much as the NPDES 
  
11        permits shortly written after the Board issued its final 
  
12        opinion and order were in keeping with such an 
  
13        interpretation.  I further believe that this 
  
14        interpretation was also in keeping with the Board's 
  
15        intent and its final opinion and order.  Region 5 USEPA 
  
16        did not object to any of the components of the Agency's 
  
17        advocated position in R94-1 prior to that action before 
  
18        the Board.  The IEPA has indicated and presented the 
  
19        Region 5 with the proposed rule and discussed that 
  
20        proposal with Region 5. 
  
21                     On November 13, 1997, a 168 notice of 
  
22        intent to sue USEPA on behalf of the Environmental Law 
  
23        and Policy Center, the Sierra Club Citizens For a Better 
  
24        Environment, McHenry County Defenders and Trout 
   
  
  
  
  
  
  
                                                               12 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        Unlimited was filed.  The intent of this suit, or the 
  
 2        intent, rather, was based on the allegation or on the 
  
 3        alleged lack of implementation of rules 44, R94-1, and 
  
 4        the alleged failure of USEPA to publish anti-degredation 
  
 5        rules for Illinois, since the then existing rules of 
  
 6        Illinois were alleged to be inadequate.  These actions 
  
 7        resulted in USEPA Region 5 changing its position 
  
 8        regarding the concept of EMW, thereby forcing the Agency 
  
 9        to adopt to develop the current useless EMW concept. 
  
10                     The IAWA felt that the implementation 
  
11        procedures of R94-1 were perfectly adequate for the 
  
12        needs of the State.  IAWA felt that the Board, the 
  
13        Agency, the regulated community and initially the 
  
14        activists' community had agreed upon a viable mechanism 
  
15        in EMW to implement a scientifically questionable and 
  
16        technically and feasible water quality standard. 
  
17        Regrettably such was not the case. 
   
18                     The IAWA member agencies must deal with the 
  
19        harsh realities of engineering, chemical and biological 
  
20        principles.  The semantics of oratory in context 
  
21        realistically accomplished nothing in terms of actual 
  
22        water quality improvement.  Science and engineering are, 
  
23        by necessity, the tools with which our society addresses 
  
24        our present water quality needs.  Consequently, the 
  
  
  
  
  
  
  
                                                               13 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        limits of our science and engineering become -- the 
  
 2        abilities become the limits of our ability to address 
  
 3        water quality problems.  No amount of discussion, 
  
 4        oratory or legal action, can realize water quality 
  
 5        improvement beyond the cost benefit limits of our 
  
 6        science and engineering. 
  
 7                     Any bitterness or acrimony detected on 
  
 8        behalf of the IAWA or me during these proceedings is 
  
 9        probably directed toward two issues and certainly not 
  
10        the Board or the Agency.  The first of these issues is 
   
11        the preconceived fallacy that more plentiful and 
  
12        stringent water quality regulations automatically result 
  
13        in water quality improvements.  This concept is absurd. 
  
14        It is the extent of our society's scientific and 
  
15        engineering capability, not our legal regulatory 
  
16        structure that will dictate the extent to which we can 
  
17        realize water quality improvement.  We do not live in a 
  
18        perfect world and we cannot have all that we want. 
  
19                     The IAWA felt that the final disposition of 
  
20        R94-1 was the result of a maneuvering to achieve 
  
21        unattainable regulatory requirements by special interest 
  
22        groups.  The absolute frustration on behalf of IAWA is 
  
23        worn out today as we attempt to do the un-bad 
  
24        regulation. 
  
  
  
  
  
  
  
                                                               14 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                     The second issue responsible for perceived 
  
 2        acrimony concerns a federal agency, which in conduct of 
  
 3        its normal review responsibilities, fails in one or both 
   
 4        of two assigned duties.  If indeed the EMW concept in 
  
 5        its intended implementation was not in keeping with the 
  
 6        Clean Water Act requirements, Region 5 should have so 
  
 7        indicated before the issue was brought before this 
  
 8        Board.  The necessary accommodations could have been 
  
 9        made, such that the Board was able to act in a 
  
10        thoroughly informed manner on an acceptable proposal. 
  
11        Such advisement was apparently not given by Region 5 in 
  
12        R94-1. 
  
13                     The second concern IAWA has regarding the 
  
14        Region 5 action in R94 relies in the reluctance of 
  
15        Region 5 to stand by its apparent original approval of 
  
16        the R94-1 proposal.  Why should the threat of a lawsuit 
  
17        be of more significant provocation to USEPA than the 
  
18        adoption of a realistic and justified water quality 
  
19        standard?  The IAWA presumes that Region 5 USEPA is in 
  
20        the business of protecting our nation's waters with a 
  
21        sound cost benefit stewardship, not in the business of 
  
22        avoiding lawsuits. 
  
23                     The IAWA and I have always felt that we 
  
24        could receive a very fair hearing on environmental 
  
  
  
  
  
  
  
                                                               15 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        issues before this Board.  This Board has developed a 
  
 2        reputation within the IAWA membership of being an 
  
 3        authority where we can take contention issues, and while 
  
 4        not always winning, at least receive a just and fair 
  
 5        hearing, while we guarantee that our concerns will be 
  
 6        heard by both the Board and the public. 
  
 7                     On the other hand, the Agency has always 
  
 8        presented a regulated community with an unquestionable 
  
 9        outline of the goals of the nation and the state for 
  
10        realizing water quality improvements and maintenance. 
  
11        However, the Agency has graciously been cognizant of the 
  
12        inherent difficulties of such goals on a site-by-site 
  
13        basis and has allowed latitude where it could, so that 
  
14        technical reality and financial stewardship have been 
  
15        considered to the fullest extent possible. 
  
16                     Together, the Board, the Agency and the 
   
17        IAWA membership have been profoundly successful in 
  
18        restoring water quality to our state and improving the 
  
19        quality of wastewater effluence.  We have been very 
  
20        successful. 
  
21                     In conclusion, I wish to restate that IAWA, 
  
22        nor I, are bitter or acrimonious toward either the Board 
  
23        or the Agency.  We solidly feel that we are all partners 
  
24        in addressing our mandate to protect and enhance the 
  
  
  
  
  
  
  
                                                               16

 1        quality of our state's waters.  Regrettably, at times, 
  
 2        some very frustrating situations appeared to be 
  
 3        inevitable.  Thank you. 
  
 4                     HEARING OFFICER GLENN:  Thank you, 
  
 5        Mr. Callahan. 
  
 6                     Dr. Sheehan? 
  
 7                     MR. KISSEL:  Do you have any questions for 
  
 8        him? 
  
 9                     HEARING OFFICER GLENN:  I prefer, if no one 
  
10        objects, we'll go ahead and hear from Dr. Sheehan. 
  
11        We'll take questions subsequent to that. 
   
12                     MR. KISSEL:  Dr. Sheehan, you understand 
  
13        you're still under oath? 
  
14                     DR. SHEEHAN:  Yes, I do. 
  
15                     MR. KISSEL:  Go ahead. 
  
16                     DR. SHEEHAN:  I will read from the prefiled 
  
17        testimony. 
  
18                     I am Robert J. Sheehan, professor of 
  
19        fisheries in zoology, and assistant director of the 
  
20        Fisheries and Illinois Aquaculture Center, Southern 
  
21        Illinois University Carbondale. 
  
22                     I am commenting today on the revised 
  
23        proposed rule filed by the Illinois Association of 
  
24        Wastewater Agencies, IAWA, and specifically issues 
  
  
  
  
  
  
  
                                                               17 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        relating to the database of spawning dates of fish that 
  
 2        I prepared in connection with this rule making.  I 
  
 3        testified in detail on this subject at the first hearing 
  
 4        to address the proposed rule filed by IAWA. 
  
 5                     The revised proposed rule adds a definition 
   
 6        for early life stage at section 302.100.  This 
  
 7        definition is consistent with my work in this matter. 
  
 8        Because the U.S. Environmental Protection Agency's 
  
 9        national criteria document, "Ambient Water Quality 
  
10        Criteria for Ammonia", 1999, on which this rule making 
  
11        is based, does not define "early life stage," 
  
12        representatives of IAWA and myself looked to other 
  
13        sources for a concise definition. 
  
14                     The ORSANCO rule making contained the 
  
15        following definition: 
  
16                     Early life stages of fish means the 
  
17        pre-hatch embryonic period, the post-hatch free embryo 
  
18        or yolk-sac fry and the larval period, during which the 
  
19        organism feeds.  Juvenile fish, which are anatomically 
  
20        rather similar to adults, are not considered an early 
  
21        life stage. 
  
22                     I believe this definition is concise and 
  
23        accurate.  I used this definition in my determination of 
  
24        when the "early life history stages present" water 
  
  
  
  
  
  
  
                                                               18 
                             KEEFE REPORTING COMPANY 
  
  
 
 1        quality criteria should be applied in Illinois. 
  
 2                     At the first hearing in this matter, Board 
  
 3        Member Flemal also inquired about the word "indigenous" 
  
 4        in describing the fish that are considered in connection 
  
 5        with the water quality standard before the Board.  I 
  
 6        believe that it is not necessary to add "indigenous," 
  
 7        and it would unnecessarily complicate this issue. 
  
 8        Certain species stocked by the Illinois Department of 
  
 9        Natural Resources, such as the striped bass or muskie, 
  
10        may not be indigenous to Illinois waters, but it might 
  
11        still be appropriate to consider the early life stages 
  
12        of these species in deriving water quality standards.  I 
  
13        believe that the limitation to fishes that are not 
  
14        salmonids adequately addresses the fish species to be 
  
15        considered.  No reproducing salmonid populations are 
  
16        found in Illinois waters that receive NPDES point source 
  
17        discharges.  Thank you. 
  
18                     HEARING OFFICER GLENN:  Thank you, 
  
19        Dr. Sheehan. 
   
20                     We will turn now to any questions that 
  
21        anyone has of either Mr. Callahan or Dr. Sheehan.  Do 
  
22        any members of the public have any questions?  We'll 
  
23        start with you all and go from there.  I see no 
  
24        questions.  If any come up, please just raise your 
  
  
  
  
  
  
  
                                                               19

 1        hand. 
  
 2                     In the meantime, do any of the board 
  
 3        members or, Anand, of the technical unit, have any 
  
 4        questions? 
  
 5                     BOARD MEMBER FLEMAL:  I wanted to thank 
  
 6        both of you for the way you have addressed some of the 
  
 7        concerns that I expressed at the first hearing in this 
  
 8        matter.  I think you've done it really quite 
  
 9        successfully. 
  
10                     There's one question regarding the 
  
11        definition from ORSANCO that I would propose.  In the 
  
12        last sentence of the early life stages definition, 
  
13        there's the phrase, "which are anatomically rather 
   
14        similar to adults."  We tend in Illinois to have 
  
15        problems when we take rules beyond the Board, 
  
16        particularly to the group called JCAR, for questions of 
  
17        hardness of definition, and words like "rather similar" 
  
18        or "like" or "appearing to be" are often brought back to 
  
19        us by this Board -- by that board asking whether we can 
  
20        find some more precision in our definition. 
  
21                     What would we -- how would we respond to 
  
22        someone raising a question of what constitutes "rather 
  
23        similar"?  Is there some way maybe that we can avoid 
  
24        having the question even being asked? 
  
  
  
  
  
  
  
                                                               20 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                     DR. SHEEHAN:  This is ORSANCO's 
  
 2        definition.  I think you could -- personally you could 
  
 3        drop the word "rather."  I don't think that -- that 
  
 4        might clear things up a little bit, not necessarily 
  
 5        everything you'd hope for. 
  
 6                     BOARD MEMBER FLEMAL:  It wouldn't sacrifice 
  
 7        too much by just dropping the word "rather"? 
  
 8                     DR. SHEEHAN:  No.  The reason I say that, 
  
 9        this is based on the anatomical similarity between the 
  
10        juvenile fish and the adult.  And as fish grow, they 
  
11        change what we call their body confirmation.  So that 
  
12        even adults, as they get older, will look different from 
  
13        the way they looked when they had, for example, newly 
  
14        became sexually mature.  There are shape changes.  So 
  
15        it's very difficult to pin down the exact anatomical 
  
16        confirmation of the fish because it changes through 
  
17        time.  And I think that similarly, by saying it's 
  
18        anatomically similar to adults, that may be the clearest 
  
19        way to express this idea. 
  
20                     BOARD MEMBER FLEMAL:  Thank you.  We'll 
  
21        take that into consideration.  That's the only question 
  
22        I have. 
  
23                     HEARING OFFICER GLENN:  Thank you. 
  
24                     BOARD MEMBER GIRARD:  I have a similar 
  
  
  
  
  
  
  
                                                               21 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        question then.  Does that mean that juvenile fish, which 
  
 2        are not anatomically similar to adults, would possibly 
  
 3        be considered an early life stage? 
  
 4                     DR. SHEEHAN:  In my opinion, if they had 
  
 5        not gone through the last transformation whereupon they 
  
 6        would become similar to adults, I believe you're 
  
 7        correct.  They could still -- may well still be 
  
 8        considered an early life history stage. 
  
 9                     BOARD MEMBER GIRARD:  Thank you. 
  
10                     BOARD MEMBER FLEMAL:  Who would make that 
  
11        determination? 
  
12                     DR. SHEEHAN:  I imagine people like 
  
13        myself. 
  
14                     When I originally prepared the spawning 
  
15        dates table and defined when the "early life history 
  
16        stage present" occurred, I -- at about a month on after 
  
17        hatching, because based on my knowledge of the species 
  
18        in Illinois that are under consideration here, they will 
  
19        hatch, undergo a couple of transformations, really, and 
  
20        actually become similar in appearance to adults within 
  
21        two to three weeks after hatching.  So I added on 
  
22        another week just to be more protective, and determined 
  
23        that for our species in Illinois, a month after 
  
24        hatching, you pretty much had an animal that was similar 
  
  
  
  
  
  
  
                                                               22 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        to the adults with all the species that I'm aware of. 
  
 2                     BOARD MEMBER FLEMAL:  The way the early 
  
 3        life stage present and absent periods are set up, in 
  
 4        effect -- and that's already been taken into 
  
 5        consideration -- in that there's a determination here 
  
 6        that it is during that period of time when the stages 
  
 7        are present and you don't have to do a site-by-site 
  
 8        determination or species-by-species determination 
  
 9        necessarily? 
  
10                     DR. SHEEHAN:  I'm not sure I follow you. 
  
11                     BOARD MEMBER FLEMAL:  My concern here is 
  
12        whether this becomes a decision that has to be made 
  
13        regularly perhaps associated with each permit, or at 
   
14        least each reach of stream, or whether, in effect, it's 
  
15        already built into the operation of the rule.  And my 
  
16        sense is that it's really the latter, rather than the 
  
17        former. 
  
18                     DR. SHEEHAN:  It's built into the operation 
  
19        of the rule, because you have to remember that the 
  
20        standards are based on sensitivity of these species. 
  
21        And for periods when the early life history stages are 
  
22        present, the standards are based on toxicity tests with 
  
23        what we call larval fishes, which is essentially a 
  
24        specimen that's several weeks younger than what we call 
  
  
  
  
  
  
  
                                                               23 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        a juvenile fish.  And it's pretty well understood that 
  
 2        as species -- as fish get older, they become, for the 
  
 3        most part, less sensitive to toxic substance. 
  
 4                     The other consideration here is that fish 
  
 5        will spawn at a given temperature, and it's really 
  
 6        temperature that dictates how rapidly an individual fish 
   
 7        proceeds to that juvenile stage.  That's pretty much 
  
 8        set. 
  
 9                     Now, spawning will occur earlier in the 
  
10        southern half of the state, but at a temperature which 
  
11        we can get a predictable developmental rate.  And so if 
  
12        we get spawning in the southern half of the state, we 
  
13        can pretty well be sure that in two to three weeks, it 
  
14        will have undergone a transformation in this juvenile 
  
15        stage.  In the northern part of the state, spawning will 
  
16        come later, but at the same temperature, such that we 
  
17        still get the same developmental rate.  So I don't think 
  
18        we need to look at this on a site-by-site basis. 
  
19                     MR. HARSCH:  I might respond, Dr. Flemal, 
  
20        to your question. 
  
21                     There is the latitude open to the Agency 
  
22        that we discussed at the first hearing under 302 (e), 
  
23        where the Agency, I believe, could make a determination 
  
24        that another period might be appropriate. 
  
  
  
  
  
  
  
                                                               24 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                     BOARD MEMBER FLEMAL:  I understand.  My 
  
 2        question really went to when we have that situation, 
  
 3        where is the determination made that the juvenile stage 
  
 4        is or is not also part of the early life stage? 
  
 5                     MR. HARSCH:  Well, I think, again, it would 
  
 6        be in accordance with the explanation at the first 
  
 7        hearing.  It would be done at the time the Agency was 
  
 8        probably converting the water quality standards, 
  
 9        effluent limitations, and looking at a given discharge 
  
10        and the impact on the receiving stream that that 
  
11        discharge would have, and might encounter another 
  
12        situation where the prescribed periods in the rule are 
  
13        not adequate. 
  
14                     It does provide them some latitude where 
  
15        it's necessary, correct, Mr. Callahan?  You testified to 
  
16        that. 
  
17                     MR. CALLAHAN:  Yeah, that was our intention 
  
18        of leaving a sentence in that paragraph. 
  
19                     And as I understand the question, the 
  
20        consideration has already been made and recommended by 
  
21        Dr. Sheehan, and it would be adopted by the Board that 
  
22        the early life stage would exist beginning in March.  So 
  
23        there would subsequently not have to be initial review 
  
24        every time you have a permit issued.  There would be 
  
  
  
  
  
  
  
                                                               25 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        something agreed upon here before the Board.  And this 
  
 2        paragraph just gives more latitude if the events and 
  
 3        circumstances should evolve. 
  
 4                     HEARING OFFICER GLENN:   If I might 
  
 5        interject here.  Mr. Harsch was sworn in at the first 
  
 6        hearing.  So he's still under oath. 
  
 7                     MR. HARSCH:  Correct. 
  
 8                     BOARD MEMBER RAO:  I've got a couple of 
  
 9        questions. 
  
10                     I was looking at Section 302.212 (c)(2) 
  
11        where we talk about the 30-day average concentration 
  
12        nitrogen, how that standard is obtained.  Could you 
  
13        clarify as to what it means to, you know, take at least 
  
14        four consecutive samples to meet a 30-day average 
   
15        concentration?  You know, does the rule intend that if 
  
16        you take an average of four consecutive samples, that 
  
17        represents a 30-day average? 
  
18                     MR. CALLAHAN:  In discussion about this and 
  
19        with the Agency, as we began development with this last 
  
20        summer -- and I certainly stand for Mr. Mosher to 
  
21        interject anything here he'd care to -- the Agency was 
  
22        concerned in trying to assess a 30-day compliance period 
  
23        initially from the standpoint of devoting resources to 
  
24        30 consecutive days of sampling, in the event they 
  
  
  
  
  
  
  
                                                               26 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        needed data for enforcement action.  So we agreed that 
  
 2        perhaps a four-day sampling of four samples collected 
  
 3        within a four -- or a 30-day period, that were 
  
 4        representative of the 24 hours within which they were 
  
 5        collected, would be adequate to determine that number. 
  
 6                     Now, that would simply be my understanding 
  
 7        of it.  And, again, I defer to Bob here for some 
   
 8        clarification.  That would principally be the method by 
  
 9        which the Agency would initially determine compliance or 
  
10        noncompliance water quality standards in the field. 
  
11                     What we would look at is dischargers and 
  
12        would be our daily monitoring of our effluence in 
  
13        setting the permit limits appropriate to that particular 
  
14        receiving stream.  We would go into that in a much more 
  
15        rigorous detail than just four days. 
  
16                     BOARD MEMBER RAO:  If you're going to ask 
  
17        this question, as in the national criteria 
  
18        document - 1999 update in the recommendations, they cite 
  
19        or recommend that, you know, they use a 30-day average 
  
20        concentration to show compliance with the chronic 
  
21        standard.  And then it says use the highest four-day 
  
22        average concentration to show compliance with the 
  
23        sub-chronic standard.  So the language that's been 
  
24        proposed deviates from what's recommended in the 
  
  
  
  
  
  
  
                                                               27 
                            KEEFE REPORTING COMPANY 
  
   
 
 1        criteria document. 
  
 2                     So that's the reason I was asking this 
  
 3        question, so we can have some clarification about how 
  
 4        these two standards are, you know, complied with by 
  
 5        dischargers. 
  
 6                     MR. CALLAHAN:  Well, the four consecutive 
  
 7        day sampling for compliance with the sub-chronic 
  
 8        standard by our intent with what we are proposing would 
  
 9        be any four consecutive days.  It could be the highest 
  
10        of the 30, most definitely.  And, again, I believe that 
  
11        this would be particularly on zero low flow streams. 
  
12        This would principally be an effluent, a historically 
  
13        effluent analysis that would be the basis for the 
  
14        setting of those limits. 
  
15                     In terms of major compliance in the stream 
  
16        itself, sub-chronic is any four consecutive days 
  
17        regardless of whether they were the highest or not. 
  
18        It's just we hypothetically would begin to sample on 
  
19        Wednesday and proceed through Saturday, and if that was 
  
20        in compliance with the sub-chronic level, fine. 
  
21                     Again, we go back to the 30-day average, 
   
22        which was brought up, and this was in response to the 
  
23        Agency having concern about being able to actually be on 
  
24        site at a given water body for 30 consecutive days and 
  
  
  
  
  
  
  
                                                               28 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        sample to determine compliance. 
  
 2                     Would you care to speak to that, Bob? 
  
 3                     HEARING OFFICER GLENN:  I'm sorry, 
  
 4        Mr. Mosher.  Could you identify yourself. 
  
 5                     MR. MOSHER:  Yeah.  My name is Robert 
  
 6        Mosher.  I work for the Illinois Environmental 
  
 7        Protection Agency, and I believe I was sworn earlier. 
  
 8                     HEARING OFFICER GLENN:  Thank you. 
  
 9                     MR. MOSHER:  There's always two issues, and 
  
10        I guess I've said this a lot lately, but we use water 
  
11        quality standards to set permit limits.  That's one 
  
12        function.  The other function is to simply tell if our 
  
13        waters are meeting the standards, and whether, you know, 
  
14        we have attainment.  That's the other function. 
   
15                     And ammonia is different in that, number 
  
16        one, we've got a new construct of a standard called the 
  
17        sub-chronic, and that by definition in the national 
  
18        criteria document, is an average over a four-day 
  
19        period. 
  
20                     And then another new thing about the 
  
21        ammonia national criterion is that instead of looking at 
  
22        the chronic over a four-day period, they say it has to 
  
23        be looked at over a longer period, and they gave 30 
  
24        days.  So that's why you see differences here compared 
  
  
  
  
  
  
  
                                                               29 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        to the metals, water quality standards, for example. 
  
 2                     We are very much concerned, and I think we 
  
 3        have satisfied ourselves at the Agency that these draft 
  
 4        rules are adequate to do both those jobs, allow us to 
  
 5        set permits' limits and allow us to assess compliance 
  
 6        with the water quality standards.  We've spent quite 
  
 7        awhile looking at that, and we think this language is 
   
 8        adequate for our purposes. 
  
 9                     BOARD MEMBER RAO:  Thank you. 
  
10                     BOARD MEMBER FLEMAL:  I would ask both of 
  
11        you perhaps to have a look at this language to see 
  
12        whether it accomplishes what I think I've heard both of 
  
13        you say it should do.  It seems to me that you want our 
  
14        four consecutive daily samples -- that "daily" is not in 
  
15        there, and when you say over at least 30 days, could it 
  
16        be over 130 days or 300 days?  Don't you mean within 30 
  
17        days or something? 
  
18                     MR. MOSHER:  No, we don't mean that at 
  
19        all.  Again, look at the metals.  There we say at least 
  
20        four days, and that could be one sample each day for 
  
21        four consecutive days.  It could be one sample every six 
  
22        weeks for a long -- much longer time period.  That's 
  
23        because our agency's routine ambient monitoring is done 
  
24        on a cycle usually of six weeks. 
  
  
  
  
  
  
  
                                                               30 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                     So for, let's say, our 305 V report to 
  
 2        Congress, we have to tell the U.S. Congress what shape 
  
 3        the waters of Illinois are in.  And we are limited by 
  
 4        our monitoring that work to provide the data and compare 
  
 5        our monitoring data to the standards.  So that's why we 
  
 6        specifically, for the metals and for ammonia, wanted 
  
 7        language that would allow a routine representative 
  
 8        sampling period that shadows what we actually do, what 
  
 9        we actually collect. 
  
10                     BOARD MEMBER FLEMAL:  I think I understand 
  
11        how you operate some of the constraints that that 
  
12        impeaches on your ability to collect data that would 
  
13        somehow support a conclusion like whether or not the 
  
14        sub-chronic standard is being met here.  But I'm still a 
  
15        little bit concerned whether this language that I see 
  
16        before me is doing what at least I thought Mr. Callahan 
  
17        was saying, in that we're looking at four consecutive 
  
18        days.  Those four days would not be consecutive? 
  
19                     MR. CALLAHAN:  For the sub-chronic, they 
  
20        are consecutive.  For the monthly standard, they don't 
   
21        necessarily have to be. 
  
22                     BOARD MEMBER FLEMAL:  In the chronic, it 
  
23        says four consecutive samples collected over a period of 
  
24        at least 30 days.  That could be four consecutive 
  
  
  
  
  
  
  
                                                               31 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        samples, which are 20 days apart or a hundred days 
  
 2        apart?  And the total time period could be anything 
  
 3        greater than 30 days.  That's the way I read it.  Am I 
  
 4        entirely wrong? 
  
 5                     MR. MOSHER:  There's some confusion here, I 
  
 6        think.  If we look at the -- and I don't even know. 
  
 7        You've got the new handout? 
  
 8                     BOARD MEMBER FLEMAL:  Yes, I do.  And on 
  
 9        the bottom of page two, going on to the rest of the 
  
10        sentence on the top of page three. 
  
11                     MR. MOSHER:  Okay.  So the bottom of page 
  
12        two (c)(2). 
  
13                     BOARD MEMBER FLEMAL:  Yes. 
  
14                     MR. MOSHER:  This is the chronic standard. 
   
15        This says that there has to be at least four samples 
  
16        collected consecutively over a period of at least 30 
  
17        days.  That would allow us to use our ambient monitoring 
  
18        network, collect the sample once every six weeks, we 
  
19        take any four consecutive of those samples, average it, 
  
20        according to the instructions in (d), and we'd be able 
  
21        to assess attainment of the chronic standard. 
  
22                     And then number three, we've got the 
  
23        sub-chronic standard.  That requires a daily sample for 
  
24        four consecutive days, and that is also averaged 
  
  
  
  
  
  
  
                                                               32 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        according to part B for assessment of the sub-chronic 
  
 2        standards. 
  
 3                     BOARD MEMBER FLEMAL:  That clarifies it. 
  
 4                     BOARD MEMBER RAO:  Just on a follow-up.  In 
  
 5        the criteria document when they talk about sub-chronic 
  
 6        standard, they say the highest four-day average within 
  
 7        the 30-day period should not exceed 2.5 times the 
   
 8        chronic criterion.  So is there any significance to 
  
 9        that, to how that sample would be taken within the 
  
10        30-day period? 
  
11                     DR. SHEEHAN:  For the sub-chronic standard, 
  
12        which is talking about (c)(3) here, basically it's a 
  
13        sample taken each of four consecutive days averaged 
  
14        together. 
  
15                     BOARD MEMBER TRISTANO:  Let me ask it this 
  
16        way.  You dropped the word "highest" to four days, and 
  
17        you didn't put the 30-day limit.  So is the highest 
  
18        4 days within 30 days?  The word "highest" is dropped 
  
19        here, and it can be any 4 days within the 30. 
  
20                     DR. SHEEHAN:  Right. 
  
21                     BOARD MEMBER TRISTANO:  And the 30-day 
  
22        limit is not here.  There's no 30-day reference to (c) 
  
23        in (3).  There is no 30-day reference. 
  
24                     DR. SHEEHAN:  Well, in (c)(2), basically it 
  
  
  
  
  
  
  
                                                               33 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        gives the Agency the option of collecting any four 
   
 2        samples within the 30-day period or any four beyond the 
  
 3        30-day period. 
  
 4                     BOARD MEMBER TRISTANO:  That's correct. 
  
 5                     DR. SHEEHAN:  Yes. 
  
 6                     BOARD MEMBER RAO:  Is that consistent with 
  
 7        the criteria document? 
  
 8                     MR. MOSHER:  If I could interject, I think 
  
 9        that word "highest" in the national criteria document is 
  
10        what's confusing us.  They're saying highest, which is 
  
11        fine.  These rules are saying any four days must meet 
  
12        the sub-chronic.  Why they said highest?  I don't think 
  
13        it gained anything there. 
  
14                     Presumably like any other standard, you 
  
15        name the period of averaging, and any four days in this 
  
16        case must meet that sub-chronic standard.  Whether it's 
  
17        the highest or the second highest in a month or the 
  
18        fourth highest in a month, it doesn't matter.  They all 
  
19        have to meet it. 
  
20                     BOARD MEMBER RAO:  Yeah.  The reason I ask 
  
21        these questions were, because in the criteria document 
  
22        where they talk about how they came up with the chronic 
   
23        standard on page 82 of the criteria document, they say, 
  
24        you know, based on the fact the minnow early life stage 
  
  
  
  
  
  
  
                                                               34 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        30-day averaging period, you know, the number is 
  
 2        justified with the restriction that the four -- the 
  
 3        highest four-day average within the 30 days is no 
  
 4        greater than the chronic criteria. 
  
 5                     So when I read that, I thought that is some 
  
 6        kind of a language between these two standards, that you 
  
 7        have a chronic criterion standard based on the fact 
  
 8        minnow data of a 30-day average and that number is 
  
 9        justified, because you have the further restrictions 
  
10        that you have to meet the sub-chronic standard for the 
  
11        highest four-day average.  So that's where, you know, I 
  
12        was a little bit confused when I saw the proposed 
  
13        language, and that's where I'm coming from.  If you can 
  
14        take a look at this, and, you know, address it in your 
  
15        comments, that's fine. 
   
16                     MR. CALLAHAN:  I always hesitate to put 
  
17        words in Bob's mouth, but I go back again to what he was 
  
18        saying about us trying to crack two eggs with one rock 
  
19        here. 
  
20                     One thing we're looking at is the 
  
21        development of NPDES permit limits, which will have a 
  
22        daily maximum, a monthly average, and if appropriate by 
  
23        the statistical analysis under this regulation, might 
  
24        even have a weekly average, which would be based on the 
  
  
  
  
  
  
  
                                                               35 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        sub-chronic standard.  That's one use of these formulae 
  
 2        and the data that would or -- and the data that would 
  
 3        contribute to that would undoubtedly be coming from 
  
 4        wastewater plant treatment discharges, which are very 
  
 5        regularly regulated or monitored.  And that's one set of 
  
 6        criteria. 
  
 7                     I think your point about the four-day 
  
 8        sub-chronic standard being used in conjunction with the 
  
 9        30-day monthly standard, chronic standard, will 
  
10        certainly come to play in that statistical analysis in 
  
11        determining a permit level. 
  
12                     What Bob is looking at is an overall 
  
13        assessment of water quality compliance, using the same 
  
14        regulation.  And perhaps data is not readily available, 
  
15        because they're monitoring that as -- and employs a 
  
16        much, much less frequent, much lower frequency than does 
  
17        the discharge monitoring.  So the same regulation, same 
  
18        rule mathematically has to be applicable to both. 
  
19                     And that's the problem that we've 
  
20        encountered with the language here that I think you're 
  
21        picking up on.  And how do we write one rule that 
  
22        addresses both sets of requirements?  Is that a fair 
  
23        statement of what you're -- Bob? 
  
24                     MR. MOSHER:  Yeah, I think you said it 
  
  
  
  
  
  
  
                                                               36 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        well. 
  
 2                     As the Agency, we'll very rarely be in a 
   
 3        position to collect a sample a day for four days in a 
  
 4        stream somewhere.  That isn't likely to be a common 
  
 5        use.  But as Mike said, in some instances, putting a 
  
 6        weekly average permit limit based on that sub-chronic 
  
 7        standard will be much more common. 
  
 8                     I think the Federal EPA, when they came out 
  
 9        with this new ammonia standard, on one hand said the way 
  
10        ammonia acts as a toxicant, we need to look at things 
  
11        over a 30-day period.  Where as before for chronic 
  
12        standards, we only looked at a four-day period.  And 
  
13        when they did that to the chronic, we also went back and 
  
14        said, well, are we missing something in between here? 
  
15        Are we missing adverse effects?  Probably we validate 
  
16        that occurs over longer time periods than an acute 
  
17        exposure, but over shorter time periods than this 30-day 
  
18        exposure.  So hence the sub-chronic standard. 
  
19                     MS. KISSEL:  I think the question is, does 
  
20        this language, is it consistent with the criteria 
  
21        document?  And it is, because you don't have to use the 
  
22        word "highest," and that is what Mr. Mosher said. 
   
23                     If you collect four samples consecutively, 
  
24        then those -- that's the highest, the lowest and the 
  
  
  
  
  
  
  
                                                               37 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        medium, because it's the only four samples you have in 
  
 2        that period.  If you collect 8 or 10 or 12, then you 
  
 3        take the four consecutive that are the highest.  That's 
  
 4        what I understand this to mean.  You don't need the 
  
 5        word -- and this responds to Dr. Flemal's question and 
  
 6        yours.  You don't need the word "highest" in this to 
  
 7        accomplish the same thing. 
  
 8                     BOARD MEMBER RAO:  But when I read the 
  
 9        criteria document, to me it seemed like you take 30 
  
10        samples, average it to show compliance with the chronic 
  
11        standard, and then you use the four highest based within 
  
12        the 30 days to show compliance with the sub-chronic, 
  
13        which is a little bit different. 
  
14                     BOARD MEMBER TRISTANO:  That's my 
  
15        understanding, too.  There's a statistical difference 
   
16        between taking 30 data points and then taking the four 
  
17        highest and average it, as opposed to taking four data 
  
18        points randomly in a consecutive order to average 
  
19        those.  And I just would like you to clarify that for 
  
20        us, and I might be misreading it because I'm new. 
  
21                     MR. CALLAHAN:  Well, at any rate, you would 
  
22        like us to become a little more definitive in the 
  
23        language in this section? 
  
24                     BOARD MEMBER RAO:  Yes.  I know it's very 
  
  
  
  
  
  
  
                                                               38 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        difficult to meet both your objectives with the proposed 
  
 2        language, and if there's any way you can ratify the 
  
 3        language to make it easier for the Agency and for the 
  
 4        dischargers, you know, that would be helpful. 
  
 5                     MR. HARSCH:  We will respond -- attempt to 
  
 6        respond in writing to that. 
  
 7                     MR. MOSHER:  Maybe a quick example here 
  
 8        would be useful. 
  
 9                     Let's say the Agency goes to Salt Creek, 
  
10        and, heck, we go every Tuesday in May and take a 
  
11        sample.  We then have -- let's say there's four Tuesdays 
  
12        in May.  We then have enough samples to average together 
  
13        to assess attainment of the chronic standard, okay? 
  
14        Because we need at least four over at least a 30-day 
  
15        period.  We have that.  We can average that.  We can say 
  
16        is this stream meeting the chronic ammonia standard or 
  
17        not. 
  
18                     Those four samples are not useful for 
  
19        evaluating the sub-chronic because they did not come on 
  
20        four consecutive days.  So we can't speak to the 
  
21        sub-chronic standard, given that data set. 
  
22                     We can, of course, speak to the acute 
  
23        standard, because each of those would be evaluated 
  
24        separately for the acute.  Like I mentioned before, it 
  
  
  
  
  
  
  
                                                               39 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        would be very rare that we would get our samplers out on 
   
 2        those four consecutive days to evaluate the 
  
 3        sub-chronic.  That's just, you know, very possibly the 
  
 4        type of sampling we probably would never do. 
  
 5                     But let's say a spill occurred or a hog lot 
  
 6        lagoon overflowed.  There's an instance where we might 
  
 7        want to get our samplers out there on Monday, Tuesday, 
  
 8        Wednesday and Thursday, in, you know, the same week to 
  
 9        get a sample.  And then we could average those four 
  
10        together and assess compliance or attainment with the 
  
11        sub-chronic.  That's how we intend it to work and -- 
  
12                     DR. SHEEHAN:  We originally proposed the 
  
13        exact language, but to make it easier on Illinois EPA to 
  
14        enforce, we change the language a little bit. 
  
15                     BOARD MEMBER GIRARD:  I just have one 
  
16        clarifying question then.  On (c)(3) here, where we talk 
  
17        about the sub-chronic standard, it sounds to me like 
  
18        what you're saying is the wording there should be any 
  
19        four-day average concentration in total ammonia 
  
20        nitrogen, rather than three. 
  
21                     MR. CALLAHAN:  That would be our objective. 
   
22                     BOARD MEMBER GIRARD:  If you have four days 
  
23        of points, or the other example that Dick gave where 
  
24        maybe you've done it over eight days, you would have 
  
  
  
  
  
  
  
                                                               40 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        different sets of combinations, but it would be any four 
  
 2        consecutive days. 
  
 3                     MR. CALLAHAN:  That's precisely our 
  
 4        intent. 
  
 5                     BOARD MEMBER RAO:  I just had one more. 
  
 6        It's a follow-up to a question I asked at the first 
  
 7        hearing about effluent permit limits. 
  
 8                     On this proposal and revision, do you 
  
 9        envision any permits will be set, you know, at levels 
  
10        more than 1.5 milligrams per liter for summer and 4.5 
  
11        milligrams either for winter? 
  
12                     MR. CALLAHAN:  Theoretically, that could 
  
13        happen.  And the reason that I say theoretically is 
  
14        because I do not know what the discharge limits are for 
  
15        all permits in the state.  By and large, I would imagine 
   
16        85, 90 percent of the permits issued in Illinois have 
  
17        1.5 or had 1.5 milligrams per liter as a summer monthly 
  
18        average, and 4.0 as a winter monthly average.  For those 
  
19        permits, anti-backslide considerations will prevent 
  
20        those dischargers getting a higher limit if they are in 
  
21        compliance with those limits.  And it's our 
  
22        understanding that most people are in compliance with 
  
23        those limits. 
  
24                     So while these would -- this standard may 
  
  
  
  
  
  
  
                                                               41 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        well indicate that there could be higher permit limits 
  
 2        acceptable across the state, most dischargers will, in 
  
 3        all likelihood, be constrained by their existing permit 
  
 4        limits as a result of anti-backsliding consideration. 
  
 5                     BOARD MEMBER RAO:  What about new 
  
 6        dischargers who, you know, come in and want a new 
  
 7        permit, and they end up with levels higher than 1.5 and 
  
 8        4.5?  New -- 
  
 9                     MR. CALLAHAN:  What regulation -- 
  
10                     BOARD MEMBER RAO:  I asked, you know, if 
  
11        you would go back and take a look to see if there's a 
  
12        need for a permit for effluent standard in this rule 
  
13        under 304, because in the earlier regulation for 
  
14        effluent modified waters -- water, we had those 
  
15        limitations in place.  So I would ask you to see if 
  
16        there's a need for those effluent limits to be 
  
17        retained. 
  
18                     MR. HARSCH:  We don't believe so.  We now 
  
19        have the revised degradation rules that would apply, 
  
20        that the new source would comply with.  There would have 
  
21        to be appropriations made, as Mr. Mosher testified in 
  
22        the first proceeding. 
  
23                     So we think that the -- if the discharger 
  
24        can demonstrate the combination of the application of 
  
  
  
  
  
  
  
                                                               42 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        the anti-degredation rules and whatever the appropriate 
  
 2        water quality based effluent limitation from these 
   
 3        proposed rules, that should be the appropriate permit 
  
 4        limitation. 
  
 5                     BOARD MEMBER RAO:  Because those -- the 
  
 6        permit limits I talked about, 1.5 and 4.5 milligrams per 
  
 7        liter, they are in the Agency's implementation draft 
  
 8        right now.  So that's the reason I ask the question, 
  
 9        whether it should be in the Board regulations and not 
  
10        the Agency's implementation draft. 
  
11                     MR. HARSCH:  That was the point Mr. Mosher 
  
12        and the Agency was going to address at some point. 
  
13                     MR. MOSHER:  Yeah, we need to try to 
  
14        clarify that. 
  
15                     That agency rule, which is part 355, was 
  
16        adopted I believe in 1999 after long, long negotiations 
  
17        between Illinois EPA, USEPA and environmental groups. 
  
18                     And the environmental groups were very 
  
19        adamant that those levels of 1.5 and 4 were achievable 
  
20        by all nitrifying discharges, nitrifying treatment plant 
  
21        discharges.  And they did not want to see levels in 
  
22        effluent limits rise above 1.5 and 4. 
  
23                     And we explained what Mr. Callahan just 
   
24        explained, that there's a federal regulation called 
  
  
  
  
  
  
  
                                                               43 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        anti-backsliding that generally prevents those, but they 
  
 2        brought up the same issue that you're bringing up.  What 
  
 3        about new dischargers? 
  
 4                     And the compromise -- I guess you could 
  
 5        call it -- reached was that if we use 50th percentile pH 
  
 6        and derives water quality based effluent limits for 
  
 7        ammonia on one of these new discharges, that we would 
  
 8        not allow the water quality base calculation to rise 
  
 9        above 1.5 or 4.  That doesn't happen very often.  We 
  
10        don't have to invoke that part of our rule very often. 
  
11        But it's there, and it provides a water quality based 
  
12        cap on the permit limit. 
  
13                     What could still happen, given that rule is 
  
14        in the 75th percentile pH was used in this calculation, 
  
15        that the limits could go as high as the standard allowed 
  
16        them to go.  There would be no cap using 75th 
   
17        percentile.  So that's the history of that part of the 
  
18        regulation. 
  
19                     It's, you know, one of those things that 
  
20        comes from extensive negotiations.  And we would intend 
  
21        to keep it that way, because I think doing anything else 
  
22        would make some of the players in that negotiation 
  
23        unhappy.  But by and large, it doesn't matter.  It 
  
24        doesn't have an influence very often in our setting of 
  
  
  
  
  
  
  
                                                               44 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        permits. 
  
 2                     MR. CALLAHAN:  May I speak to the issue a 
  
 3        moment? 
  
 4                     I think the 1.5 and 4 that you're 
  
 5        referencing in 355, 304, principally are two numbers 
  
 6        which have been recognized as best available technology 
  
 7        numbers.  That's why they were codified as they were. 
  
 8                     I speak from our own experience at our 
  
 9        treatment plant in Bloomington and Normal.  For decades 
  
10        we have sampled our receiving stream daily along with 
   
11        our effluent.  And by using that site-specific water 
  
12        quality data, we're able to have numbers significantly 
  
13        higher than 1.5 under the existing regulation in the 
  
14        summer and also higher than 4 in the winter.  And the 
  
15        difference is temperature, stream pH, a variety of 
  
16        things, but site-specific data, a lot of site-specific 
  
17        data has allowed that. 
  
18                     So 1.5 and 4 are not across-the-board 
  
19        blanket numbers at this point.  They were recognized in 
  
20        the discussions Bob has described as being levels of 
  
21        attainability. 
  
22                     There are situations such as ours, which I 
  
23        think are probably not too common, where there are 
  
24        numbers that are in excess of those monthly averages. 
  
  
  
  
  
  
  
                                                               45 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        Our limit is based on each month.  Each month has an 
  
 2        individual limit based upon the volume of data that we 
  
 3        have.  So I believe June is 1.6 and September is 2.2. 
   
 4        So those are higher than the 1.5 that we're talking 
  
 5        about here. 
  
 6                     BOARD MEMBER RAO:  My concern was when I 
  
 7        saw that language in the Agency draft, I thought a new 
  
 8        discharger could come and make an argument 
  
 9        that -- saying where's the authority for the Agency to 
  
10        enforce these caps?  I mean, it's not giving the board 
  
11        regulations.  So that's the reason I asked that 
  
12        question. 
  
13                     HEARING OFFICER GLENN:  Yes? 
  
14                     MS. WILLIAMS:  I'm Ms. Deborah Williams, 
  
15        counsel for Environmental Protection Agency.  I don't 
  
16        believe I have been sworn. 
  
17                [Whereupon Ms. Williams was duly sworn.] 
  
18                     MS. WILLIAMS:  I just think I wanted to 
  
19        make one legal point that touches on the question 
  
20        Mr. Rao raised at this time and last time. 
  
21                     It's our position that the language you're 
  
22        referring to in part 2, it says shall not exceed 1.5.  I 
  
23        mean, 355 is not an effluent limit in any way, per se. 
  
24        It's a procedure by which the Agency determines whether 
   
  
  
  
  
  
  
                                                               46 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        or not the 50th percentile is available to be used in 
  
 2        setting a permit limit or not.  It's just a procedure 
  
 3        for determining whether we look at 75th percentile or 
  
 4        50th percentile pH in setting a permit limit.  It's not 
  
 5        any kind of effluent limit or any kind of cap that 
  
 6        was -- although the issue of what was achievable maybe 
  
 7        was discussed in those negotiations, it hasn't been the 
  
 8        Agency's position that we looked at that, and set some 
  
 9        kind of effluent limit cap.  It's just a procedure for 
  
10        setting permit limits. 
  
11                     Does that help at all? 
  
12                     BOARD MEMBER RAO:  I don't have the draft 
  
13        in front of me right know, but, you know, when I read 
  
14        it, I thought it said if you use 50th percentile, then 
  
15        the cap is 1.5 and 4.  I mean, it seemed like a limit, 
  
16        not, you know, when you can use 50th percentile. 
  
17        There's no restriction. 
   
18                     MS. WILLIAMS:  I think, actually, it says 
  
19        if it goes above 1.5 or 4, then you have to go back to 
  
20        75th percentile. 
  
21                     HEARING OFFICER GLENN:  Is there a comment 
  
22        in the back? 
  
23                     MR. TWAIT:   Yes.  I'm Mike Twait, and I 
  
24        haven't been sworn. 
  
  
  
  
  
  
  
                                                               47 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                 [Whereupon Mr. Twait was duly sworn.] 
  
 2                     MR. TWAIT:  When we take the water quality 
  
 3        standard to the permit limit, what we start out with 
  
 4        using is a 75th percentile pH value.  If that value is 
  
 5        above 1.5 and 4, that's what we go with.  If the 50th or 
  
 6        if the 75th percentile value is less than 1.5 in the 
  
 7        summer or less than 4 in the winter, then we use the 
  
 8        50th percentile pH.  And if we use the 50th pH, then it 
  
 9        cannot go up 1.5 or 1.4, 1.5 and 4.0. 
  
10                     So I just wanted to clarify that the 1.5 
  
11        and 4 is only when we use the 50th percentile pH.  If we 
   
12        use the 75th percentile pH, it can be above that. 
  
13                     BOARD MEMBER RAO:  Thank you. 
  
14                     HEARING OFFICER GLENN:  Are there any 
  
15        further questions? 
  
16                     THE REPORTER:  Would you mind repeating 
  
17        your name? 
  
18                     MR. TWAIT:  Scott Twait, T-w-a-i-t. 
  
19                     HEARING OFFICER GLENN:  Thank you. 
  
20                     Let's go off the record for just a moment 
  
21        please. 
  
22                      [Off-the-record discussion.] 
  
23                     HEARING OFFICER GLENN:  Back on the 
  
24        record. 
  
  
  
  
  
  
  
                                                               48 
                            KEEFE REPORTING COMPANY 
  
  
 
 1                     BOARD MEMBER RAO:  It's just a 
  
 2        clarification for the record. 
  
 3                     We talked a lot about, you know, pH, and, 
  
 4        you know, 50th percentile, 75th percentile.  Would it be 
  
 5        possible for the Agency to introduce into the record the 
  
 6        typical pH in, you know, Illinois streams, if you have 
   
 7        that information? 
  
 8                     MR. MOSHER:  Well, we certainly have that 
  
 9        information. 
  
10                     BOARD MEMBER RAO:  Then we can make some 
  
11        calculations and see where these numbers come out. 
  
12                     MR. MOSHER:  Are you asking for what is the 
  
13        typical 50th percentile and 75th percentile?  Because 
  
14        pH, just by nature, is spread over a wide range, 
  
15        depending on season, weather conditions, flow 
  
16        conditions. 
  
17                     BOARD MEMBER RAO:  Just the general range, 
  
18        you know, for some major Illinois streams. 
  
19                     MR. MOSHER:  Okay.  We can easily do that, 
  
20        yes. 
  
21                     BOARD MEMBER RAO:  Thank you very much. 
  
22                     HEARING OFFICER GLENN:  Thank you.  Are 
  
23        there any further questions or comments here this 
  
24        morning?  Seeing none, I would like to set a date for 
  
  
  
  
  
  
  
                                                               49 
                            KEEFE REPORTING COMPANY 
  
  
 
 1        the filing of the public comments. 
  
 2                     It is anticipated that the Board will 
  
 3        receive the transcript in this matter in a week.  We 
  
 4        will post it on our Web site within a few days of 
  
 5        receipt of the transcript.  Assuming the Board gets the 
  
 6        transcript on or about May 1st, I will set the public 
  
 7        comment filing date then as May 15th. 
  
 8                     The mailbox rule will apply.  So if you put 
  
 9        your comment in the mail on May 15th, the Board will 
  
10        consider it timely filed.  We would appreciate any 
  
11        comments that anyone cares to make. 
  
12                     And I believe that is all we have this 
  
13        morning. 
  
14                     I want to thank everyone on behalf of the 
  
15        Board for your attendance and participation here this 
  
16        morning.  And I will put a hearing officer order out at 
  
17        the conclusion of the hearing to firm up that public
