    POST ilEA RING BRIEF OF THE lLIJINOIS ENVIRONMENTAL
    PROTECTION AGENCY
    Respondent, the Illinois Environmental Protection Agency ("Illinois EPA")
    by
    onc of its
    attomeys, Richard C. Warrington Jr., hereby files its Post Hearing Brief.
    I.
    INTRODUCTION
    1..
    This National Pollutant Discharge Elimination System ("NPDES") permit appeal
    concems the operation of the main sewage treatment plant ("Plant',) of the City of Rock
    Island
    ("City"or UPetitioner'"). The City operates the Plant ullder NPDES pennit No. IL
    00307893.
    II.
    CHLORINE RESIDUAL

    The Illinois EPA joins in the request to reevaluate the chlorinl: residual applicable
    to this permit, with a limit of 1.0 milligrams per Liter ("mglL") until such testing of

    chlorine residual limit. (Tr.
    OO~73
    p. 8)1
    Ill.
    PLANT CAPACITY
    3.
    The J1Jinois EPA and the City have agreed to incorporate the record of the
    Variance case, PCB
    98~164
    into this pennit appeal record. (Tr. 00,73 p. 7) However.
    although the facts may be mutual between the two proceedings, the standard of review
    for the llHnois Pollution Control Board ("Illinois PCB'!) is distinct in each. In a pennit
    apl-'eal, the standard is whether the application demonstrates that the facility will not
    cause a
    violation oftho Illinois Envirolln'Jp-ntal Protection Act ("Act
    U
    )
    or the regulations
    thereunder. 41 S .1LCS 5/39 (1998) The Illinois EPA is required to specify thoso terms and
    conditions which
    mayb~
    required to accomplish.the pUJPosesand provisions ofthis Act.
    415 ILCS S/39(b)
    4.
    In the ease ofthis NPDES permit, the plant capacity has been specified as 16
    million callons per day ("MOD") for the design maximum flow ("DMF') ever
    ~inec
    tho
    Mayor ofthe City and their engineer applicd for the permit in 1970. (Record p. 353, line
    C-34) Tlle DMF was again specified as 16 MOD in the Combined Sewer Ovcrflow
    Exception
    proceeding, PCB 85
    H
    214. May 9, 1986. (Record p. 284) Yn particular, the City
    represented to the Illinois PCB that cedain specified improvemeJ'lls would allow
    "operation of the treatrnent plant at the design maximum level of 16 MOD and
    improvements
    to the North Slope lntc::rceptor to aSSllre that maximum available transport
    capacity will be utilized prior to ovcrfk"..,

    Compliance Plan
    ("Mep")
    was subsequently approved
    by
    the JJJinojs EPA on July 1.
    1986 specifying this upgrade. (Record p.
    ~
    ..;
    J
    The DMF of 16 MOD was again specified
    in tho NPDES pCfalit modified on July 17, 1998. (Record p. 159) Although the City
    could have sought relief, the City Council concluded that it had made a commitment to
    providing an Sn 6 MOD plant. (Tr. 98-164 p. 38)
    5.
    The City attempts
    to
    argue that a clarification between the terms "maximum
    practicable flow't and DMF, as requested by tho United States Enviromnental Protection
    Agency ('"USEP A") to implcm(:nt the lllinois PCB' s Order in PCB
    85~214,
    May
    9~
    1986
    is
    an error. Pursuant to the NPDES
    progtam~
    draft permits are reviewed by USEPA
    before issued by the Illinois EPA. In this case, USEPA recognized that the use of
    "maximum practicable flow" was not defined in the draft permit. (Record p. 90) Tbe tcnll
    is not defined by the JlIinois PCB, although it is used in 36 Ill. Adm. Code 306.303 in the
    context of sewer efficiency. The
    Cjty
    argues that tho maximum practicable flow, if the
    . tenn is applied to the treatment plant and not to the sewers is less than 15 MOD.
    Testimony by Mr. McS'!Viggin, called as an adverse witness by the CitYt indicated that
    there was a reasonuble possibility that the treatment plant improvements constl11cted
    in
    the early 1970's would have been capable of meeting secondary treatment limits at a
    DMF of 16 MOD. (Tr.
    98~
    164 p. 68) Mr. McSwiggin also proposed a definition for
    maximum practicable flow as appiied to treatment works.
    (tr.
    98-164 p. 75)
    6.
    It
    should also be noted that the regulations of the Illinois PCB require conditions
    as least as stringent as applicable federal regulations in 35 ut. Adm. Code 309.146(e).
    The USEP A has promulgated 40 CFR 122 .41 (c) that provides:

    It
    shan not be a defense for a.
    permittee .in an enforcement action that it would
    hnve
    been necessary to halt or
    reduce the pennittcd activity in order to maintain compliance with tbe c-Onditions

    The Illinois EPA includes this provision as standnrd condition 3 in every NPDES permit.
    (Record p. 18) .
    IV.
    OUTFALL 007
    7.
    The dispute oyer whether outfall 007 should be characterized as a sanitary sewer or a
    P.
    06/09
    combined newer requires an analysis of the only
    tw\l
    alternatives availablo undel' the regulations
    of the Illinois PCB. Under the definition of a combhwJ sewer, a sewer is combined if it was
    designed and constructed to receive both wastewater and land runoff. (See 35 Ill. Adm. Cod.J
    301.255) A sewer is sanitary ifit carries wastewatu-A' together with ineidcntalland runoff
    ~~""e
    35
    III. Adm. Code 301.375)
    The
    problC'.Jn in the apl)Jh:ation of these defiuitions js Olat some of tho
    sewers trihutary to cutfhll 007 weI" originally designed and constructed as combined sewers, but
    then reconstructed to separate out street drains into a new stonn sewer system. The lemaining
    sewer, nllhough now lacking the land runCi.:: .!.:om tllc street drains, admits stonnwater fTOr.: a
    variety of private sounies. The amount of this stormwatt'f !low is more than incMental. (Tr.OO"
    73 p, 17)
    Conseql1cnt1y~
    the sewer tributary to outfall 007 hIlS perfOlmancc
    characteristi~s
    not
    satislYing either rcgqlatory definition.
    It
    was reconstructed from being 11 combined sewer yet stm
    canies an excessivo amount of stormwnter.
    8.
    This sewer was first addressed by the JUinois PCB in PCB 80-212. (Record p. 338)
    Aithougb the Illinois i'CB did not fin.J that is was a sanitary sewer (Tr. 00-73 p. 12), it did
    describe the manholes upstream ofthe lift station liS 3urcharging ordinary domestic sewage
    during wet weather periods. (Record p. 338) The lllinois I'ea did not describe it
    as
    a combined
    S6Wo!f and the City and the llIinois EF A addressed it as a sanitary sewer in development of the

    City's municipal compliance plan ("MCPIJ). (Tr. OOg'l3 p. 12) TIle City did not seek an exception
    fol' this discharge under 35 111. Adm. Code 306.Subpart D as it did for the eso discbarge at the
    main treatment plant.
    8.
    The
    m~icipal
    compliance plan was approved as a project to correct infiltration/inflow to
    eliminate all sanitary t;ewer overflows. (Record p. 279, 277) Obviously, the MCP was not
    successful in removing all sanitary iScwer overflows and the lllinois EPA has attempted to
    engineer a solution using the combined sewer overflow concepts of first flush a.nd capture of 1 0
    times the dry weather flow. (Tr. 00-73 p. 21) Nonc:ilclcss, the applicable NPDES peTJllit listed
    outfall 007 as a prohibited sanitary aewer discharge. ("fr. 00-73 p. 16) The Illinois EPA
    bclicvcs~
    with the City, that after the completion of certain improvements thnt the discharge from outfall
    007 wilt not continue. (Tr.
    OO~73
    p. 19)
    V.
    CONCLUSION
    9.
    Ofthe three appeal points raised by the City, the chlorine limitation can be resolved by
    provision of an'interim
    ~imit
    until additional information can be generated and provided to
    th~
    Illinois EPA. The question of the proper DMF for the main treatment plant is resolved by
    consideration oftha evidence that the City asked for that capacity rating in the original permit
    application, confirmed 16 MGD as the resulting DMF 1n the eso Exception proceeding PCB
    85~214,
    lInd affilmed it rather than rerating the plnnt or seeking carlier relicf. Conse,qucmly the
    DMF of tho pJant and the threshold that must be met before bypassi1)g of untreated sewage must
    remain ttl 16 MOD. The oharacterization oCthe dischargo from outfaU 007 should rem.ain as a
    sanitary sewer overflow based on the long undcrstnnding of its nature before the Illinois
    pca by
    the City and the Illinois EPA that it is a sanitary sewer, with an Ullsatisfactory attemllt to correct

    its genesis as a combined sewer. The Illinois EPA believes that recognition as a leaking sanitary
    sewer
    will be only temporary until the discharge is eliminated completely.
