    IN THE MATTER OF:
    )
    R87—22
    SITE—SPECIFIC RULE CHANGE AT
    35
    ILL. ADM. CODE PART
    304,
    SUBPART B
    (CIPS NEWTON STATION)
    PROPOSED RULE.
    SECOND NOTICE.
    ORDER OF THE BOARD
    (by J.
    Marlin):
    This matter comes before the Board on a petition for site—
    specific relief filed by Central Illinois Public Service Company
    (CIPS)
    on July 17, 1987.
    Specifically, CIPS
    is seeking relief
    from the requirement of Section 304.124(a)
    as
    it pertains to
    effluent limits for total suspended solids
    (TSS).
    The relief
    would apply to the discharge from CIPS’
    ash pond system at its
    Newton generating station
    (Newton).
    Instead of the
    15 milligrams
    per liter
    (mg/i) standard imposed
    in Section 304.124(a),
    CIPS
    wishes
    to be subject to the following effluent limits:
    30 mg/i
    as
    a
    30—day average and 100 mg/i
    as
    a daily maximum.
    On March 24, 1988,
    the Board proposed for First Notice a
    rule,
    which
    if adopted, would exempt CIPS from the TSS discharge
    limit
    imposed in Section 304.124(a).
    However,
    the Board proposed
    that CIPS’
    ash pond system be subject
    to the following limits:
    30 mg/i monthly average and 50 mg/i daily composite
    for TSS and
    15 mg/i monthly average and 30 mg/i daily composite for non-
    volatile TSS.
    The Board’s proposed rule was published
    in the
    Illinois Register on April 22,
    1988
    12
    Ill. Reg.
    7065.
    The
    Board’s rationale for proposing this rule is contained
    in the
    Proposed Opinion of March
    24,
    1988.
    The Board received only one public comment during First
    Notice;
    CIPS filed
    its comments on May 17,
    1988.
    (P.C.
    #1).
    The
    Illinois Environmental Protection Agency filed no First Notice
    comments.
    In its comments,
    CIPS reviews
    the record and concludes that
    the Board’s proposed rule
    is “fully acceptable.”
    (P.C.
    #1,
    p.
    3).
    The Board
    finds
    no reason to alter
    its proposal.
    As a
    result,
    the Board hereby proposes for Second Notice the following
    amendments which are to be filed with the Joint Committee on
    Administrative Rules.

    SITE SPECIFIC RULES
    AND EXCEPTIONS NOT OF GENERAL APPLICABILITY
    Section 304.216
    Newton Station Suspended Solids Discharges
    The limitation on the discharge of total suspended solids
    (TSS)
    contained
    in Section 304.124(a) does
    not apply to the discharge
    from the ash pond system of Central Illinois Public Service
    Company’s Newton Station (CIPS),
    located
    in Jasper County.
    Instead,
    CIPS’
    ash pond system discharge shall not exceed 30 mg/i
    monthly average and
    50 mg/i daily composite for TSS, and 15 mg/i
    monthly average and
    30 mg/i daily composite for non—volatile
    TSS.
    The definitions of Section 304.104(b) apply to these
    effluent limits.
