INTRODUCTION
Dissolved oxygen is essential to aquatic organisms for aerobic respiration. DO occurs between water molecules as microscopic bubbles of oxygen that fish “breathe” through their gills.
1
Human activities, including biochemical oxygen demand or “BOD” and nutrient discharge, and natural processes affect DO levels in Illinois waters. The DO general use water quality standard is critical to many other regulatory programs, including “impairment” assessments and Total Maximum Daily Load or “TMDL” under Section 303(d) of the federal Clean Water Act (33 U.S.C. § 1313(d)). By its authority under the Environmental Protection Act (Act) (415 ILCS 5 (2006)) and to reflect the current science, the Board is proposing to update the existing DO water quality standard, which was adopted in 1972.
The Board’s responsibility in this rulemaking arises from the Act, which charges the Board to “determine, define, and implement the environmental control standards applicable in the state of Illinois.” 415 ILCS 5/5(b) (2006). Under Section 13 of the Act, the Board is granted specific rulemaking authority to establish water quality standards. See 415 ILCS 5/13 (2006). Section 13(a)(1) of the Act specifically addresses dissolved oxygen:
| (a)
| The Board, pursuant to procedures prescribed in Title VII of this Act, may adopt regulations to promote the purposes and provisions of this Title. Without limiting the generality of this authority, such regulations may among other things prescribe:
|
| | | |
| (1)
| Water quality standards specifying among other things, the maximum short-term and long-term concentrations of various contaminants in the waters, the minimum permissible concentrations of dissolved oxygen and other desirable matter in the waters, and the temperature of such waters. 415 ILCS 5/13(a)(1) (2006) (emphasis added). |
| |
As noted, the Board adopted Illinois’ current general use water quality standard for dissolved oxygen in 1972, at which time the Board found it “essential to an adequate fish population.” Effluent Criteria, Water Quality Standards, Water Quality Standards Revisions for Intrastate Waters, R70-8, R71-14, R71-20, slip op. at 3 (Jan. 6, 1972). The standard is presently set forth at 35 Ill. Adm. Code 302.206 and reads as follows:
Section 302.206 Dissolved Oxygen
Dissolved oxygen (STORET number 00300) shall not be less than 6.0 mg/l during at least 16 hours of any 24 hour period, nor less than 5.0 mg/l at any time. 35 Ill. Adm. Code 302.206.
Accordingly, the current standard permits dissolved oxygen to be less than 6.0 milligrams per liter (mg/L) no more than 8 hours in any 24-hour period, but at no time is dissolved oxygen allowed to fall below 5.0 mg/L. Section 302.206 is set forth in Part 302’s Subpart B (“General Use Water Quality Standards”), which “contains general use water quality standards which must be met in waters of the State for which there is no specific designation (35 Ill. Adm. Code 303.201).” 35 Ill. Adm. Code 302.101(b); see also 35 Ill. Adm Code 302.201. Generally, “all waters of the State must meet the general use standards of Subpart B of Part 302,” except as otherwise specifically provided in the Board’s regulations, such as for waters designated as secondary contact and indigenous aquatic life waters. See 35 Ill. Adm. Code 303.201, 303.204.

At first notice, the Board recognized that the State’s current DO standard is outdated and needs to be amended consistent with USEPA’s 1986 National Criteria Document or “NCD,” as adapted to Illinois waters. In the NCD, USEPA recommends separate DO criteria for coldwater and warmwater biota. While the coldwater criteria address the protection of salmonids, the warmwater criteria are meant to protect nonsalmonids, which include many coldwater and “coolwater” fish, plus all warmwater fish. Exh. 2 (NCD) at 2. The warmwater criteria protect the early life stages of warmwater fish as sensitive as channel catfish and other life stages of fish as sensitive as largemouth bass. Id. In addition, the NCD provides for the establishment of seasonal criteria based on the life stages of aquatic organisms present as long as data is available to accurately determine the presence or absence of the more sensitive stages. Id. at 4. The early life stages include embryonic and larval stages and all juvenile forms to 30-days after hatching. Id. at 34.
The NCD recommends a daily minimum to ensure that no acute mortality of sensitive species occurs because of low DO concentrations. Exh. 2 (NCD) at 36. For early life stages, the NCD recommends that the averaging period should not exceed 7 days to adequately protect the most sensitive life stages of aquatic organisms. A 30-day average is recommended for other life stages. The NCD also recommends the use of a 7-day mean minimum value for other life stages to prevent significant episodes of continuous or regularly recurring exposures to DO concentrations at or near the lethal threshold. Id.
The current Illinois standard for DO was adopted 14 years before the NCD was issued by USEPA. Exh. 23 at 7. Not surprisingly then, the NCD’s criteria for DO address several elements not addressed by Illinois’ current standard: differences in sensitivity to low DO among types of fish or macroinvertebrates; differences in DO sensitivity depending on the life stages of fish; and practical considerations to account for occasional natural occurrences of low DO. Id. at 5.
Given the wide array of aquatic life and conditions across Illinois, the Board found at first notice that the current Illinois DO standard is not sufficiently sophisticated. PC 96 at 1, citing Exh. 23 at 1; PC 101 at 1; PC 102 at 2, 5; PC 103 at 1, 16; Exh. 14 at 1; Exh. 32 at 1-3; Statement at 4-5. As the Board noted in its first-notice opinion, almost all of the participants who have articulated a position in this rulemaking favor amending the current dissolved oxygen water quality standard for general use waters. There is also much consensus in the record on how the current standard should be amended, such as by adopting DO standards that change seasonally based on the life stages of fish.
The two primary areas of disagreement among the rulemaking participants prior to first notice were (1) whether to include the month of July in the early life stages timeframe and (2) whether certain stretches of Illinois streams should have more protective DO standards than the rest of the general use waters based on the presence of allegedly DO-sensitive aquatic organisms. At first notice, the Board proposed to include July in the early life stages period and to include designated stream segments for enhanced DO protection. The Board continues to do so at second notice. As provided in its most recent public comment and as discussed below, IAWA now supports including July in the early life stage period but still opposes designating stream segments for enhanced DO protection. See PC 113.
The amendments proposed today for second notice should significantly improve the current DO standard. Unlike the current DO standard, the proposed amendments take into account the varied DO requirements of aquatic communities and the diverse range of natural aquatic conditions present across Illinois. The amendments will also allow both public and private resources to be focused on those waters most impacted by low DO.
OVERVIEW OF THE BOARD’S MAIN FINDINGS AT FIRST NOTICE
The following is a brief summary of the main findings made by the Board in its 98-page first-notice opinion of July 12, 2007. First, the Board found that Illinois’ current general use water quality standard for dissolved oxygen needs to be amended and that those amendments should be based primarily on USEPA’s NCD for DO. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 12-14 (July 12, 2007) (first notice).
Next, the Board agreed with IAWA’s proposed approach of having a two-season DO standard, one more protective for the sensitive early life stages of fish and another for other life stages. Further, the Board proceeded to first notice with IAWA’s proposed numeric DO levels as follows, at least with respect to the vast majority of general use waters: for early life stages, a daily minimum DO concentration of 5.0 mg/L and a seven-day mean of 6.0 mg/L DO; for other life stages, a daily minimum DO concentration of 3.5 mg/L and a seven-day mean minimum of 4.0 mg/L DO. As proposed by DNR and IEPA, and ultimately agreed to by IAWA, the Board also proposed for first notice a 30-day mean DO standard of 5.5 mg/L for other life stages. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 34-35 (July 12, 2007) (first notice).
The Board found that the analyses of several grab and semi-continuous DO monitoring datasets provided in this record indicate that the current Illinois DO standard does not account for the seasonal variation and diurnal fluctuations of DO naturally occurring in streams. Beyond that, however, the Board found that helpful conclusions cannot be drawn at this time from these DO datasets for the purposes of this rulemaking. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 46-49 (July 12, 2007) (first notice).
The Board agreed with DNR and IEPA that certain stream segments, approximately 8% of general use stream miles in Illinois, require incrementally enhanced DO standards based on the presence of meaningful amounts of DO-sensitive aquatic organisms. Accordingly, the Board proposed for first notice that these stream segments, identified in proposed Appendix D to Part 302, have the following DO standards: for early life stages, a daily minimum DO concentration of 5.0 mg/L and a seven-day mean of 6.25 mg/L DO; for other life stages, a daily minimum DO concentration of 4.0 mg/L, a seven-day mean minimum of 4.5 mg/L DO, and a 30-day mean DO standard of 6.0 mg/L. The Board noted that if a discharger believes these more protective DO standards are not warranted for a given stream segment, the discharger may seek site-specific relief from the Board, such as an adjusted standard or site-specific rule under the Act. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 68-74 (July 12, 2007) (first notice).
To protect late spring and summer spawning, the Board found that the month of July should be included in the early life stages (i.e., March through July), as proposed by DNR and IEPA, rather than having the early life stages timeframe end on June 30, as IAWA had proposed. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 79-81 (July 12, 2007) (first notice).
As proposed by DNR and IEPA, and agreed to by IAWA, the Board also proposed for first notice a narrative DO standard for quiescent and isolated sectors of general use waters, such as wetlands and waters below the thermocline in lakes, to ensure that the full array of general use waters are protected. The numeric DO standards would not apply in these isolated waters where naturally-occurring DO concentrations cannot reasonably be expected to attain numeric values set for most general use waters. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 84-85 (July 12, 2007) (first notice).
At first notice, the Board declined to adopt the following suggestions made during this proceeding: (1) to express the DO water quality standard as percent saturation rather than as concentration in mg/L; and (2) to include a minimum DO level of 6.5 mg/L for all general use waters when water temperature is 10°C or below. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 87-89 (July 12, 2007) (first notice). The Board also declined to require that any IEPA “implementation rules” for DO monitoring or permitting be filed in this docket, but the Board did add language to the DNR/IEPA proposal, more specifically describing the 7-day mean minimum, the 7-day mean, and the 30-day mean. Id. at 92-94.
Additionally, the Board did not include in its first-notice proposal a “waiver” for urban-impacted streams or a separate “wet weather standard” based on stormwater runoff. Finally, the Board found that the first-notice proposal would not have an adverse impact on the People of the State of Illinois. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 96-97 (July 12, 2007) (first notice).
PROCEDURAL HISTORY
On April 19, 2004, IAWA filed its rulemaking proposal to amend Illinois’ general use water quality standard for dissolved oxygen.
3
The Board issued an order on May 6, 2004, accepting the IAWA proposal for hearing. DNR and IEPA filed their joint proposed revisions to the DO standard on April 4, 2006. Hearings concluded in November 2006 and public comments were filed as recently as June 2007.
As Toby Frevert, Manager of the Division of Water Pollution Control for IEPA, testified:
Illinois’ general use dissolved oxygen standard carries more significance than many of our other water quality standards and there is a wide diversity of opinion, perspective and attitude among the various constituencies participating in the proceeding. Exh. 14 at 2.
Given the significance of the DO general use water quality standard and the varied views of the rulemaking participants on how it should be revised, the Board accommodated the wishes of the participants and allowed this rulemaking to proceed at a pace that would allow for continued stakeholder discussions. To that end, the hearing officer scheduled hearings only when the participants stated that they were ready to proceed and only after the hearing officer, at the participants’ request, conducted six status conferences and received eight status reports over the course of nearly two years.
The Board held five public hearings over six days in this rulemaking: (1) June 29, 2004, in Chicago; (2) August 12, 2004, in Springfield; (3) August 25, 2005, in Chicago; (4) April 25, 2006, in Springfield; and (5) November 2-3, 2006, in Springfield. The following 20 persons testified at the hearings indicated:
| ·
| Dennis Streicher, Director of Water and Wastewater for the City of Elmhurst (first, second, and third hearings, and fifth hearing);
|
| ·
| John Callahan, Executive Director of the Bloomington and Normal Water Reclamation District of McLean County (first and second hearings);

The Board hearing officer accepted 41 hearing exhibits into the record. The hearing exhibits are described in Appendix I to this opinion and order. Upon receipt, the transcripts of the hearings were placed in the Clerk’s Office On Line (COOL) on the Board’s Web site at
www.ipcb.state.il.us
.
4
Many other documents from this rulemaking record are available through COOL, including Board opinions and orders, hearing officer orders, and public comments.
As required by Section 27(b) of the Act (415 ILCS 5/27(b) (2006)), the Board requested, in a letter of May 11, 2004, that the Department of Commerce and Economic Opportunity (DCEO) conduct an economic impact study (EcIS) for this rulemaking. In a letter of June 22, 2004, DCEO declined to perform an EcIS, noting its limited fiscal resources. When provided the opportunity at hearing, no one testified about DCEO’s response. Tr.2 at 159.
The Board received 110 public comments prior to its first-notice decision.
5
Those public commenters are listed in Appendix II to this opinion and order. The first-notice public comment period ended on September 17, 2007, 45 days after publication in the Illinois Register of the proposed rule changes. See 31 Ill. Reg. 11028 (Aug. 3, 2007). The Board received four additional public comments during the first-notice public comment period:
| ·
| PC 111 filed by the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) on August 30, 2007.
|
| ·
| PC 112 filed by Dr. Thomas Murphy, Professor Emeritus of Chemistry, DePaul University on September 17, 2007.
|

DISCUSSION
Several issues raised prior to first notice continued to be of concern to one or more participants after first notice: (1) subjecting designated stream segments to more protective DO standards; (2) the technical feasibility and economic reasonableness of meeting the proposed water quality standards; (3) the lack of “implementation rules”; and (4) expressing the DO water quality standard as concentration in mg/L rather than as percent saturation.
IAWA also asks the Board to specify, in these rules, the factors that would have to be demonstrated to receive site-specific relief from the new DO standards. In addition, IEPA proposes a small but important clarifying change to the first-notice rule language that required measuring DO attainment based on “calendar days.” Further, as requested by the Board, IEPA commented on the potential for designating stream segments by “river miles.”
The Board will address each of these areas in turn.
Designating Stream Segments for Enhanced DO Standards
IAWA agrees “with all of the modifications to [its] original petition except the establishment of a different dissolved oxygen standard for specified stream segments designated as enhanced segments.” PC 113 at 2. IAWA contends that the proposed DO standards for enhanced stream segments are not based on “sound” science, or supported by field data. Id. IAWA states that it reluctantly supports including July in the early life stage period because of the scientific basis for protecting late spawning organisms, even though the Board’s decision to include July “with cooler months,” according to IAWA, ignores meteorological conditions. Id., n.1.
IAWA contends that while the Board has broad authority to adopt water quality standards, including DO standards, under Section 27 of the Act, the authority is not unlimited. The Board must, continues IAWA, consider the existing physical conditions, including the nature of the existing receiving water. IAWA argues that “existing [water quality] data indicates that many of the proposed enhanced segments do not now meet the proposed dissolved oxygen standard.” PC 113 at 3. According to IAWA, selecting “enhanced segments” on the basis of existing habitats, and the possibility that those stream segments would support DO-sensitive species in the future, is wasteful and not based on science. Id.
IAWA also asserts that the Board’s decision to adopt enhanced DO standards for certain stream segments has a cost impact on the State and taxpayers. PC 113 at 3. The segments that do not comply with the DO standards, IAWA explains, will have to be placed on the 303(d) list for the “ultimate development” of TMDLs. Id. IAWA maintains that studying and establishing these TMDLs will be “ineffective and unnecessary” in the end:
There is no evidence that the dissolved oxygen concentrations lower than the proposed standards in these segments is due to the impact from any point or nonpoint source discharges. It may be entirely possible that many of these segments, given there existing physical condition and nature, may not support dissolved oxygen levels that will comply even absent the impact of any discharges. Id.
IAWA argues that its assessment of the NCD and proposed DO standards have “withstood the test of several years of evaluation and field measurements that have continued to support” IAWA’s position. PC 113 at 3. IAWA acknowledges the need for enhanced protection for some waters, but opposes designating enhanced stream segments without “ground truthing” data to support the designation. Id. IAWA maintains that adopting the first-notice proposal would result in designating stream segments that may never achieve the proposed enhanced DO standards and leave out other segments that may need enhanced protection. Id. at 3-4.
As noted in the first-notice opinion, the Board’s proposed amendments to the DO standards are largely based on IAWA’s proposal. The significant first-notice changes made to the IAWA proposal, and opposed by IAWA at that time, were the extension of the early life stage period and the inclusion of enhanced DO standards for certain stream segments. The Board welcomes IAWA’s support for including July in early life stage period. However, the Board disagrees with IAWA’s position that requiring the more protective DO standards for designated stream segments, roughly 8% of Illinois’ general use stream miles, is not based on sound science. The Board’s first-notice opinion addressed the concerns expressed in IAWA’s most recent comment in great detail. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 68-74 (July 12, 2007) (first notice). The Board finds that IAWA has not raised any new issues or presented any new information to convince the Board to change its course regarding the enhanced DO standards for particular stream segments.
As discussed in the Board’s first-notice opinion, the process of selecting the stream segments targeted for enhanced protection was based on extensive stream-specific biological information. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 73 (July 12, 2007) (first notice). DNR and IEPA established the presence of “meaningful amounts” of DO-sensitive organisms in specified Illinois streams by relying on extensive fish and macroinvertebrate data from approximately 1,100 stream sites across the State. Further, the State agencies relied on reasonable biological measures, and threshold values based on data from healthy streams to identify stream sites with meaningful amounts of DO-sensitive organisms. The Board reiterates its earlier finding that the biological data and scientific literature on the DO-sensitivity of aquatic life are more helpful than the limited DO datasets for setting DO water quality standards at levels that meet the needs of aquatic life.
When setting water quality standards, as discussed at first notice, the Board places significant weight on adopting a standard that fully protects aquatic life, rather than simply trying to arrive at a standard that would be met by current stream conditions. Frevert, Manager of the Division of Water Pollution Control for IEPA, testified about IAWA’s questioning of how stream segments with samples violating the proposed enhanced DO standard could yet be home to “meaningful amounts” of DO-sensitive organisms:
The fact that they are lower doesn’t mean it’s a fully protective condition. It’s possible that DO sensitive organisms are in place and under some degree of stress, still hanging on to life, where we think a higher standard is appropriate anyway pursuant to the Clean Water Act procedures and the need for the standard to be protective. I don’t think we want to set a standard that’s on the ragged edge so the slightest little deviation from that standard has the system collapse. *** That doesn’t mean that every system where those higher organisms can live is at the water quality condition we want or the standards we set . . . . [T]he fact that we say a standard is warranted doesn’t mean it has to be an existing condition. Tr.5 at 30-31.
If stream segments do not meet the proposed DO standards upon adoption, the Board expects that those stream segments would be assessed in accordance with the requirements of Section 303(d) of the federal Clean Water Act. That provision requires states to identify and list waters that do not meet applicable water quality standards or do not fully support their designated uses. This list of impaired waters, known as the “303(d) list,” is submitted to USEPA for review and approval. The federal Clean Water Act also requires that a TMDL be developed for each pollutant of an impaired water body. A TMDL must consider all potential sources of pollutants, whether point or nonpoint. It also takes into account a margin of safety, which reflects scientific uncertainty, as well as the effects of seasonal variation.
A new DO general use water quality standard in Illinois will impact these federally-driven requirements. Importantly, the new standard should be better tailored than the current DO standard for identifying waters that are actually DO-impaired. One of the primary objectives of updating the standard is to “bring in some pragmatism,” in the words of Frevert, and “pare back that list and help us find those places that really do need the attention,” that is, “those streams with true DO problems.” Tr.5 at 32.
Technical Feasibility and Economic Reasonableness
In its most recent public comment, MWRDGC states that, based on its 2005-2007 hourly DO data, “significant portions of the Des Plaines River System will immediately be in non-compliance” upon the effective date of the new DO water quality standards. PC 111 at 2. MWRDGC describes the compliance of this data with the proposed DO standards (for the daily minimum, 7-day mean of daily minima, and 30-day mean of daily means) as ranging from 50% to 100%. Id., Tables 1-3. MWRDGC maintains that its hourly DO monitoring “indicates that several reaches within the Des Plaines River System cannot be reasonably expected to comply” with the proposed standards. Id. According to MWRDGC, reaches of the Des Plaines River System are “conducive to significant water column algae growth and, consequently, high magnitude diurnal DO fluctuations, especially during the summer months.” Id. at 3. MWRDGC states that it is troubled by “standards which will immediately result in such widespread water quality violations due, in large part, to natural processes.” Id.
The Board appreciates MWRDGC providing additional monitoring data for this record. Initially, the Board must reemphasize, however, that it “does not establish an ambient water quality standard for DO based on whether Illinois waters presently comply with the standard.” See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 96 (July 12, 2007) (first notice). The Board’s primary task in this rulemaking is:
| to establish the “minimum permissible concentrations of dissolved oxygen” that will protect aquatic organisms in general use waters based on the scientific evidence. [415 ILCS 5/13(a)(1) (2006); see also PC 103 at 12.] In doing so, the Board fulfills its responsibility under the federal Clean Water Act to, in IEPA’s words, “update outdated standards to reflect the current science.” [PC 103 at 12.] Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 96-97 (July 12, 2007) (first notice).

Section 27(a) of the Act directs the Board to take into account the “technical feasibility and economic reasonableness of measuring or reducing the particular type of pollution” when conducting a substantive rulemaking. 415 ILCS 5/27(a) (2006). The new DO standard likely will indirectly impact technical and economic issues for particular pollutants in discharges. Section 27(b) of the Act requires the Board to determine whether a proposed substantive regulation “has any adverse economic impact on the people of the State of Illinois.” 415 ILCS 5/27(b) (2006). A new DO standard has the potential to primarily affect wastewater dischargers (e.g., POTWs, industrial dischargers, and agricultural point and nonpoint sources) that discharge oxygen-depleting substances, including BOD and nutrients. Tr.4 at 80-84; Statement at 2. The Board finds that the issues described by MWRDGC, however, would not be caused by this rulemaking.
As the Board found at first notice, there is no dispute in this record that there are Illinois streams not meeting Illinois’ current DO standard, or that both the IAWA proposal and DNR/IEPA proposal would “result in some significant (but smaller) number of exceedances [violations].” PC 103 at 14. As IEPA notes:
In nearly every instance, this rulemaking is expected to be less restrictive than the current [DO] standard and therefore less likely to yield exceedances (violations) of no environmental significance. PC 103 at 11; see also Tr.4 at 161 (Lanyon, General Superintendent of MWRDGC, conceded on cross-examination that neither IAWA’s nor DNR/IEPA’s proposal “would impose a stricter DO standard than we have on the books today”).
IEPA goes further, maintaining that because the DNR/IEPA-proposed DO standards more accurately reflect aquatic community needs, the joint-agency proposal “will actually be economically beneficial by more accurately focusing environmental management resources” on waters “in need.” PC 103 at 11. The Board, in its first-notice opinion, agreed with IEPA and found that the amendments proposed for first notice would not have an adverse impact on the People of the State of Illinois. Nothing has since been provided to the Board that would warrant the Board changing this finding at second notice.
Moreover, as discussed at first notice, the Act provides several ways to seek either temporary or permanent site-specific relief from rules of general applicability, in the form of petitions for variances, adjusted standards, and site-specific rules. These mechanisms allow for case-by-case demonstrations before the Board based on factors such as compliance with the general rule imposing an “arbitrary and unreasonable hardship” (415 ILCS 5/35(a) (2006)), “factors relating to that petitioner are substantially and significantly different from the factors relied upon by the Board in adopting the general regulation” (415 ILCS 5/28.1(c)(1) (2006)), and the factors of “technical feasibility and economic reasonableness” (415 ILCS 5/27(a) (2006)).
In addition, while the Board makes no findings concerning the specific stream reaches referred to by MWRDGC, the proposed rules do include a narrative standard, reflecting the fact that under certain natural conditions unaffected by deleterious human activities, dissolved oxygen may periodically decline below numeric standards to concentrations typically considered acutely harmful to aquatic life. USEPA observed this phenomenon in its NCD:
Naturally-occurring [DO] concentrations may occasionally fall below target criteria levels due to a combination of low flow, high temperature, and natural oxygen demand. Under these circumstances the numerical criteria should be considered unattainable, but naturally-occurring conditions which fail to meet criteria should not be interpreted as violations of criteria. Although further reductions in [DO] may be inadvisable, effects of any reductions should be compared to natural ambient conditions and not to ideal conditions. Exh. 2 (NCD) at 28.
Back to top
To address these unavoidable situations, one component of the proposed narrative standard requires that quiescent and isolated sectors of general use waters be maintained at sufficient DO concentrations to support their natural ecological functions and resident aquatic communities. The proposed numeric standards for DO do not apply in these quiescent and isolated sectors, but rather only in the main body of streams, in the water above the thermocline of thermally stratified lakes and reservoirs, and in the entire water column of unstratified lakes and reservoirs.
Implementation Concerns
MWRDGC takes issue with proposed Section 302.206(d)(3) requiring that DO attainment measurements “represent the true daily minima and daily means.” PC 111 at 1. MWRDGC construes this language as suggesting that “some degree of continuous monitoring will be required, but [the rule language] does not identify how many daily values should be captured in order to ‘assure’ they are representative.” Id. According to MWRDGC, the “sampling intensity is the crux of determining how resource intensive” DO monitoring must be “to comply with proposed standards.” Id. MWRDGC acknowledges that the Board is not required to develop implementation rules in order to adopt water quality standards, but maintains that the “lack of guidance on this matter leaves the regulated community with an unfortunate level of uncertainty.” Id.
Dr. Murphy also suggests that implementation rules be part of the proposal. Dr. Murphy states that measurement uncertainties will have implications on the effectiveness of the proposed rules. To account for the uncertainties, Dr. Murphy suggests including a margin of error by adding one or more mg/L to each of the proposed standards. PC 112 at 5.
The Board discussed implementation concerns extensively at first notice. As stated in that opinion, the Board declined to require the filing of implementation rules in this docket. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 90-94 (July 12, 2007) (first notice). The Board appreciates MWWRDGC and Dr. Murphy renewing their concerns over how the new DO standards will be implemented. At one point in this proceeding, Environmental Law & Policy Center, Prairie Rivers Network, and Sierra Club filed a “motion to suspend consideration of proposed amendments to the dissolved oxygen standard pending development of draft implementation rules.” Ultimately, the motion was withdrawn and none of these environmental groups filed any public comment on the Board’s first-notice decision to not require implementation rules in this docket.
Initially, the Board again notes that developing or adopting IEPA implementation “rules” is not necessarily a prerequisite to USEPA approval of these DO water quality standards. IEPA Resp. to Mot. to Suspend at 4-5 (Aug. 6, 2004). Moreover, Frevert, Manager of the Division of Water Pollution Control for IEPA, testified that he does not anticipate IEPA adopting any regulations on DO sampling:
I don’t anticipate any agency rules on that. We certainly establish our own field practices and field methodology, and we may identify some guidelines there for applications in certain types of circumstances, but that -- again, that’s our field methods and manuals. That’s not a regulation or an agency rule. Tr.5 at 253.
The new DO standards will now include 7- and 30-day averages to help ensure that aquatic organisms are not subject to chronically low DO. This critical enhancement to Illinois’ current standard alone is expected to lead to additional monitoring beyond that presently performed to determine compliance with 6.0 mg/L during 16 hours of any 24-hour period and 5.0 mg/L at any time. The Board found that subsection (d) of the DNR/IEPA-proposed Section 302.206 provided a detailed account of how to assess attainment of daily mean and minimum DO values. At first notice, however, the Board agreed with MWRDGC and the environmental groups that subsection (d) could benefit from specific language on how to assess attainment of the 7-day mean minimum, the 7-day mean, and the 30-day mean. To address these concerns, the Board added language on determining the 7- and 30-day values, and the proposed first-notice amendments described how to assess attainment of the DO mean and minimum values. Those provisions are further refined here at second notice, as discussed below. Again, the DO data needed to make these assessments will doubtlessly inform the eventual monitoring process. The Board continues to agree with IEPA that the temporal detail and measurement techniques necessary to determine compliance with the DO standard are “an inherent part of the standard itself, not separate implementation procedures.” IEPA Resp. to Mot. to Suspend at 3 (Aug. 6, 2004).
On carrying out a measuring program to determine attainment of the DO standard, Frevert testified:
It is their responsibility to assure that the way they design their monitoring system and the way they collect their data, it is truly representative, not misrepresentative of the normal variation. You can’t go out and get three samples at nine at night, ten o’clock at night and eleven o’clock at night and pretend they represent the full 24-hour period. And I’m not trying to specify how many samples is the minimum to do it correctly. I think that would be a difficult or impossible task, but you must -- if you’re collecting data and you’re using it to draw conclusions or make
assertions about compliance with this standard, it’s your responsibility to look at the representativeness of your monitoring scheme and its statistical reliability. Tr.4 at 75-76.
IEPA has stated in this record that DO is not routinely included as a National Pollutant Discharge Elimination System (NPDES) permit effluent concentration and that even for dischargers located immediately upstream of stream segments selected for enhanced DO protection, IEPA does not plan to modify its permit issuance approach. According to Frevert:
The DO standard that we’ve selected for any particular stream, whether it be tier one or tier two, is based on our understanding of the relative sensitivity of the biological community that we believe is there. That in and of itself is not going to have much, if any, impact at all on permit limitations, so we would do a normal permitting. If indeed the stream is impaired, whether it be in a level one or level two classification, and a point source is a significant contributing factor
to it, I’m not sure the answer to that is immediately go and try to tweak the permit. It’s try to figure out what’s going on and to what extent that treatment facility is really not adequately controlling their waste, and we’re not going to know that, and I don’t believe whether the stream falls in tier one or tier two is going to make any difference in the way we treat that situation. Tr.4 at 122-23; see also Tr.5 at 254-56 (less than 1% of Illinois NPDES discharge permits have conditions requiring in-stream monitoring to assess DO attainment; the vast majority of the permits have discharge limits of 10 or 20 mg/L CBOD5 set under the deoxygenating wastes rule (35 Ill. Adm. Code 304.120)).
As at first notice, the Board has carefully reviewed the record and prior relevant rulemaking precedent. The Board finds that the participants have not raised any new issues or provided any new information to convince the Board that implementation rules must or should be a part of this docket. This docket has appropriately developed to the point where the Board can propose for second notice what the dissolved oxygen condition of Illinois general use waters should be. That task of the Board’s is “fundamentally different [from] . . . day-to-day implementation and management and monitoring and enforcement decisions.” Tr.1 at 142-43 (quoting Frevert). The Board again finds that the focus of this proceeding should remain on the water quality standards themselves, the adoption of which should not be delayed.
DO Saturation Versus Concentration
During the first-notice public comment period, Dr. Murphy provided further comment on using percent saturation to establish a DO standard for aquatic life. Regardless of the units used to describe dissolved oxygen in the proposed rule, Dr. Murphy believes problems for aquatic life exist at low temperatures with the proposed DO standards. Dr. Murphy concedes that the proposed rules would “not create problems for waters that are warm, because these are the temperatures at which the large majority of the studies have been performed.” PC 112 at 3. On the other hand, Dr. Murphy finds no evidence in the record of studies at cold temperatures to support the proposed rule. Id.
According to Dr. Murphy, the availability of dissolved oxygen to an organism decreases as the water temperature gets colder. PC 112 at 1. Dr. Murphy calculates that water with 3.5 mg/L dissolved oxygen at 0°C is 24% saturated, and he equates the saturation value to 2 mg/L dissolved oxygen at 25°C. Id. at 1, 3. Dr. Murphy cites to a reference from Nathan Hawley, et al., EOS 87, 313 (2006),
6
describing conditions of hypoxia in Lake Erie when DO falls below 2 mg/L. Id. at 4-5.
Dr. Murphy renews his suggestion that the DO standard correspond to a percent saturation. Previously, Dr. Murphy suggested: (1) dividing the tiers into two or more temperature ranges and using percent saturation to determine a DO standard in mg/L (PC 83 at 5, PC 105 at 3); and (2) using 6.5 mg/L as a DO standard in waters at or below 10°C (Tr. 5 at 51-54). In his latest public comment, Dr. Murphy modifies his earlier suggestions by recommending a percent saturation of 33% or greater and applying it to different temperature ranges: 5 mg/L at 0°C, or 4 mg/L at 5-10°C. PC 112 at 4.
The Board reiterates that USEPA’s NCD does not appear to contemplate a temperature-triggered DO standard. The two-concentration criteria structure presented in the NCD and followed by the Board at first notice represents USEPA’s preferred approach to date. Although dissolved oxygen concentration, partial pressure, and percent saturation are all interrelated, the Board finds that relying on a criteria based on concentration in mg/L is the more direct and practical approach. As to the supporting body of scientific evidence, currently most DO monitoring data and the scientific literature regarding fish are based on mg/L.
At first notice, the Board invited public comment on whether other states with conditions similar to those in Illinois have adopted numeric DO standards, the applicability of which is based explicitly on water temperature. See Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25, slip op. at 89 (July 12, 2007) (first notice). The Board has not received any public comments identifying any such states. IEPA is unaware of any USEPA Region 5 state (i.e., Indiana, Michigan, Minnesota, Ohio, and Wisconsin, in addition to Illinois) that has adopted numeric DO standards with applicability based on water temperature. PC 114 at 4.
As with the 6.5 mg/L DO standard proposed by Dr. Murphy and the environmental groups before first notice for waters at or below 10°C, the Board finds that there is not enough evidence in this record to demonstrate that Dr. Murphy’s latest proposal of 5 mg/L at 0°C or 4 mg/L at 5-10°C is necessary or appropriate to supplement the proposed numeric and narrative standards for Illinois general use waters.
Factors for Site-Specific Relief
IAWA agrees with the Board’s position that site-specific relief may be available to a discharger if enhanced DO standards are not warranted for a given stream segment. IAWA argues, however, that these proposed regulations should prescribe the specific factors to be demonstrated by an affected discharger in order to successfully obtain relief from the Board. PC 113 at 4.
The Board agrees that such factors would be helpful to persons seeking such relief and also to the Board. The Board has in the past specified by rule the factors for seeking site-specific change from rules of general applicability. See, e.g., 35 Ill. Adm. Code 620.260, 811.320. The Board declines, however, to amend the proposed DO water quality rules to address site-specific relief at this stage of the rulemaking. IAWA has not proposed any specific factors for Board consideration. The Board welcomes IAWA or any other person to file a rulemaking proposal addressing the factors for site-specific relief from the proposed DO standards. In the meanwhile, the Board will continue to evaluate requests for site-specific or adjusted water quality standards by relying on the existing statutory and regulatory criteria. See, e.g., 415 ILCS 5/28.1(a), (c) (2006); 35 Ill. Adm. Code 104.406, 104.426.
Calendar Days Versus Consecutive 24-Hour Periods
In its public comment, IEPA proposes amendments to the first-notice rule language regarding assessing attainment of DO standards. Specifically, IEPA now suggests that Section 302.206(d), as proposed for first notice, be modified to avoid restricting the determination of daily means and daily minima to a “calendar day.” PC 114 at 2. According to IEPA, limiting measurements to a calendar day, as opposed to any period of 24 consecutive hours, can result in “unusable dissolved oxygen measurements that are otherwise valid and meaningful.” Id. at 2-3. IEPA explains that while it originally proposed the calendar-day restriction, the language “unintentionally prevents using the results of any dissolved oxygen monitoring period that did not begin and end specifically at midnight.” Id. at 3.
The Board agrees with IEPA that requiring measurements to be based on “calendar days” is unnecessarily restrictive and could lead to wasting resources. As IEPA notes, for example:
[I]f hourly monitoring of dissolved oxygen began on Monday at 9:00 AM for seven “calendar days”, none of the hourly measurements from Monday 9:00 AM to the same Monday at midnight (15-hour period) could be used to determine a daily mean or daily minimum. Similarly, assuming the monitoring ended eight days later on Tuesday at 9:00 AM, none of the hourly measurements from the immediately preceding period of Monday at midnight to Tuesday at 9:00 AM (9-hour period) could be used. PC 114 at 3.
The Board accordingly adopts for second notice the following revisions (double-underlined and stricken through) to Section 302.206(d), as proposed by IEPA:
d) Assessing attainment of dissolved oxygen mean and minimum values.
| 1)
| Daily mean is the arithmetic mean of dissolved oxygen concentrations in 24 consecutive hours values measured in a single 24-hour calendar day. |
| |
| 2)
| Daily minimum is the minimum dissolved oxygen concentration in 24 consecutive hours value as measured in a single 24-hour calendar day. |
| |
| 3)
| The measurements of dissolved oxygen used to determine attainment or lack of attainment with any of the dissolved oxygen standards in this Section must assure daily minima and daily means that represent the true daily minima and daily means. |
| |
| 4)
| The dissolved oxygen concentrations value used to determine a in calculating or determining any daily mean or daily minimum should not exceed the air-equilibrated concentration value. |
| |
| 5)
| “Daily minimum averaged over 7 days” means is the arithmetic mean of daily minimum dissolved oxygen concentrations in seven consecutive 24-hour periods values from the current and previous 6 calendar days. |
| |
| 6)
| “Daily mean averaged over 7 days” means is the arithmetic mean of daily mean dissolved oxygen concentrations in seven consecutive 24-hour periods values from the current and previous 6 calendar days. |
| |
| 7)
| “Daily mean averaged over 30 days” means is the arithmetic mean of daily mean dissolved oxygen concentrations in 30 consecutive 24-hour periods values from the current and previous 29 calendar days. |
| |
River Miles
IEPA recognizes that “river miles” are commonly used to identify particular points along “large, navigable Illinois rivers.” PC 114 at 3. For two reasons, however, IEPA opposes using river miles to designate the stream segments subject to enhanced DO standards. First, IEPA states that it is not aware of “readily available and reliable stream mileages for the large majority of Illinois streams.” Id. Second, IEPA believes that identifying stream segment endpoints by river mile is “more prone to error than is identifying segment endpoints by standardized map coordinates, i.e., latitude and longitude.” Id. at 3-4. IEPA explains that “river mile” identification:
requires measuring entire lengths of streams; the magnitude of potential error in such measurements depends directly on the resolution of the maps being used. In contrast, identifying points by standardized map coordinates does not require extensive linear measurements directly from a map of a specified resolution. Id. at 4.
The first-notice list of “Stream Segments for Enhanced Dissolved Oxygen Protection” appears as Appendix D to Part 302. The proposed Appendix D designates stream segments by basin name, segment name, segment number, end points by latitude and longitude, and county. For example, the first two of the stream segments proposed for enhanced DO protection appeared for first notice as follows:
| 302.Appendix D

Proposed Amendments to Dissolved Oxygen Standard 35 Ill. Adm. Code 302.206, R04-25 (July 12, 2007) (first notice).
The Board, at first notice, solicited comment on MWRDGC’s suggestion that those stream segments proposed to receive more protective DO standards also be identified by “river mile.” MWRDGC did not expand upon or renew its request in its first-notice public comment. The record of this proceeding lacks river mile information on the stream segments at issue, let alone such information from a reliable source. It bears keeping in mind that the stream segments identified in Appendix D are subject to enhanced DO standards. The precise extent of those segments is accordingly significant. Based on this record, the Board finds that the latitude and longitude designations in Appendix D, as proposed for first notice, provide the warranted reliability. The Board therefore agrees with IEPA and declines at second notice to propose river mile designations in Appendix D.
CONCLUSION
Illinois’ current general use water quality standard for dissolved oxygen, adopted in 1972, is outdated and too simplistic to account for the natural variability of waters and their aquatic communities across this State. The DO standard proposed today for second notice is consistent with USEPA’s NCD as adapted to Illinois waters and reflects the current science. By allowing both public and private resources to be concentrated on general use waters that are truly impaired by low DO levels, the proposal promises to significantly and economically enhance the protection of Illinois aquatic life.
The Board’s second-notice proposal, as at first notice, includes the essential elements of IAWA’s proposal, but with critical additions originally proposed by DNR and IEPA. The IAWA proposal of a two-season DO standard with averaging and DO values consistent with the NCD “warmwater” criteria is a major step toward modernizing the Illinois standard, but it does not go far enough. It is true that most of Illinois’s aquatic organisms can be characterized as having the DO-sensitivity of “warmwater” organisms and that most spawning is completed in the spring. As this record shows, however, IAWA’s proposal does not adequately address the fact that there are significant “intermediate” organisms and “late spring and summer spawners” in Illinois. The Board accordingly is proposing for second notice that designated stream segments (approximately 8% of Illinois’ 71,394 general use stream miles) have enhanced DO standards based on the presence of meaningful amounts of DO-sensitive organisms and that the month of July be included in the sensitive “early life stages” timeframe (i.e., March through July). The record demonstrates that these additional protections over and above the IAWA proposal are necessary to fully protect Illinois aquatic life.
The Board agrees with Joel Cross, Acting Manager of DNR’s Watershed Protection Section, that this proposal is not a “lowering of dissolved oxygen standards within some waters during certain times of the year, but rather [a] focusing [of] needed protection for most sensitive types and life stages of aquatic life where required.” Tr.4 at 46. The second-notice proposal provides enhanced DO protection when and where it is most needed. Further, the narrative standard proposed today ensures that the full range of general use waters in Illinois is protected against low DO.
Additionally, the Board recognizes that after implementation of the final DO standard adopted in this rulemaking, further study may reveal that regulatory relief is warranted for specific stream stretches. The Act has mechanisms already in place, such as adjusted standards, that allow for case-by-case, site-specific relief when the necessary demonstrations are made before the Board.
The Board thanks all of those who have participated in this proceeding. The rulemaking record had benefited greatly from the active participation of many individuals and organizations, including Environmental Law & Policy Center, Prairie Rivers Network, Sierra Club, MWRDGC, and the Office of Lieutenant Governor Pat Quinn. The Board expresses deep gratitude to IAWA, DNR, and IEPA for their especially thorough contributions to this record. The Board appreciates the continued participation of IEPA, IAWA, MWRDGC, and Dr. Murphy and thanks them for their first-notice public comments.
At second notice, the Board amends its first-notice rule language at Section 302.206(d) for measuring DO-standard attainment by replacing “calendar days” with “consecutive 24-hour periods,” as recommended by IEPA. The Board’s proposal today is otherwise substantively unchanged from its first-notice proposal.
ORDER
The Board directs the Clerk to cause the filing of the following proposed rule amendments with JCAR for its second-notice review. Proposed deletions to the current rules at 35 Ill. Adm. Code 302 are stricken and proposed additions are underlined. Additionally, for ease of comparison, deletions from rule text proposed at first notice are stricken; additions are double-underlined.

Unless otherwise specified, the definitions of the Environmental Protection Act (Act) [415 ILCS 5] and 35 Ill. Adm. Code 301 apply to this Part. As used in this Part, each of the following definitions has the specified meaning.
| |
"Acute Toxicity" means the capacity of any substance or combination of substances to cause mortality or other adverse effects in an organism resulting from a single or short-term exposure to the substance.
|
| |
|
| |
"Adverse Effect" means any gross or overt effect on an organism, including but not limited to reversible histopathological damage, severe convulsions, irreversible functional impairment and lethality, as well as any non-overt effect on an organism resulting in functional impairment or pathological lesions which may affect the performance of the whole organism, or which reduces an organism's ability to respond to an additional challenge.
|
| |
|
| |
"Chronic Toxicity" means the capacity of any substance or combination of substances to cause injurious or debilitating effects in an organism which result from exposure for a time period representing a substantial portion of the natural life cycle of that organism, including but not limited to the growth phase, the reproductive phases or such critical portions of the natural life cycle of that organism.
|
| |
|
| |
"Criterion" means the numerical concentration of one or more toxic substances derived in accordance with the procedures in Subpart F of this Part which, if not exceeded, would assure compliance with the narrative toxicity standard of Section 302.210 of this Part.
|
| |
“Early Life Stages” of fish means the pre-hatch embryonic period, the post-hatch free embryo or yolk-sac fry, and the larval period, during which the organism feeds. Juvenile fish, which are anatomically similar to adults, are not considered an early life stage.
|
| |
"Hardness" means a water quality parameter or characteristic consisting of the sum of calcium and magnesium concentrations expressed in terms of equivalent milligrams per liter as calcium carbonate. Hardness is measured in accordance with methods specified in 40 CFR 136, incorporated by reference in 35 Ill. Adm. Code 301.106.
|
| |
|
| |
"Mixing Zone" means a portion of the waters of the State identified as a region within which mixing is allowed pursuant to Section 302.102(d) of this Part.
|
| |
|
| |
“Thermocline” means the plane of maximum rate of decrease of temperature with respect to depth in a thermally stratified body of water.
|
| |
|
| |
"Total Residual Chlorine" or "TRC" means those substances which include combined and uncombined forms of both chlorine and bromine and which are expressed, by convention, as an equivalent concentration of molecular chlorine. TRC is measured in accordance with methods specified in 40 CFR 136, incorporated by reference in 35 Ill. Adm. Code 301.106.
|
| |
|
| |
"Toxic Substance" means a chemical substance that causes adverse effects in humans, or in aquatic or terrestrial animal or plant life. Toxic substances include, but are not limited to, those substances listed in 40 CFR 302.4, incorporated by reference in 35 Ill. Adm. Code 301.106, or any "chemical substance" as defined by the Illinois Chemical Safety Act [430 ILCS 45]
|
| |
|
| |
"ZID" or "Zone of Initial Dilution" means a portion of a mixing zone, identified pursuant to Section 302.102(e) of this Part, within which acute toxicity standards need not be met.

SUBPART B: GENERAL USE WATER QUALITY STANDARDS
Section 302.206 Dissolved Oxygen
General use waters must maintain dissolved oxygen concentrations at or above the values contained in subsections (a), (b) and (c) of this Section. Dissolved oxygen (STORET number 00300) shall not be less than 6.0 mg/L during at least 16 hours of any 24 hour period, nor less than 5.0 mg/L at any time.
a) General use waters at all locations must maintain sufficient dissolved oxygen concentrations to prevent offensive conditions as required in Section 302.203 of this Part. Quiescent and isolated sectors of General Use waters including but not limited to wetlands, sloughs, backwaters and waters below the thermocline in lakes and reservoirs must be maintained at sufficient dissolved oxygen concentrations to support their natural ecological functions and resident aquatic communities.
| b)
| Except in those waters identified in Appendix D of this Part, the dissolved oxygen concentration in the main body of all streams, in the water above the thermocline of thermally stratified lakes and reservoirs, and in the entire water column of unstratified lakes and reservoirs must not be less than the following: |
| |
| 1)
| During the period of March through July, |
| |
| A)
| 5.0 mg/L at any time; and |
| | |
B) 6.0 mg/L as a daily mean averaged over 7 days.
2) During the period of August through February,
A) 3.5 mg/L at any time;
B) 4.0 mg/L as a daily minimum averaged over 7 days; and
C) 5.5 mg/L as a daily mean averaged over 30 days.
| c)
| The dissolved oxygen concentration in all sectors within the main body of all streams identified in Appendix D of this Part must not be less than: |
| |
| 1)
| During the period of March through July, |
| |
A) 5.0 mg/L at any time; and
B) 6.25 mg/L as a daily mean averaged over 7 days.
| 2)
| During the period of August through February, |
| |
A) 4.0 mg/L at any time;
B) 4.5 mg/L as a daily minimum averaged over 7 days; and
C) 6.0 mg/L as a daily mean averaged over 30 days.
d) Assessing attainment of dissolved oxygen mean and minimum values.
| 1)
| Daily mean is the arithmetic mean of dissolved oxygen concentrations in 24 consecutive hours values measured in a single 24-hour calendar day. |
| |
| 2)
| Daily minimum is the minimum dissolved oxygen concentration in 24 consecutive hours value as measured in a single 24-hour calendar day. |
| |
| 3)
| The measurements of dissolved oxygen used to determine attainment or lack of attainment with any of the dissolved oxygen standards in this Section must assure daily minima and daily means that represent the true daily minima and daily means. |
| |
| 4)
| The dissolved oxygen concentrations value used to determine a in calculating or determining any daily mean or daily minimum should not exceed the air-equilibrated concentration value. |
| |
| 5)
| “Daily minimum averaged over 7 days” means is the arithmetic mean of daily minimum dissolved oxygen concentrations in seven consecutive 24-hour periods values from the current and previous 6 calendar days. |
| |
| 6)
| “Daily mean averaged over 7 days” means is the arithmetic mean of daily mean dissolved oxygen concentrations in seven consecutive 24-hour periods values from the current and previous 6 calendar days. |
| |
| 7)
| “Daily mean averaged over 30 days” means is the arithmetic mean of daily mean dissolved oxygen concentrations in 30 consecutive 24-hour periods values from the current and previous 29 calendar days. |
