    PROPOSED OPINION AND ORDER OF THE BOARD
    (By J. Marlin):
    This matter comes before the Board upon
    a proposal by the
    Illinois Environmental Protection Agency
    (Agency) to amend 35
    Ill. Adm. Code 304.120, Deoxygenating Wastes,
    filed with the
    Board
    on April 23,
    1986.
    Hearings on this proposal were held by
    the Board on June 24, 1986 at Peoria and June 27, 1986 at
    Effinghain.
    On January 5,
    1987,
    the Department of Energy and
    Natural Resources
    (DENR)
    filed with the Board its negative
    declaration.
    The Economic and Technical Advisory Committee
    concurred with DENR’s determination.
    On March
    5,
    1987,
    the Board
    adopted
    a Proposed Rule,
    First Notice concerning
    the Agency’s
    proposal.
    The Board proposed
    for First Notice a significant
    portion of the Agency’s proposal.
    The Board opened Docket
    B
    in
    this proceeding
    to further consider the aspects of the Agency’s
    proposal
    that were not proposed at First Notice.
    During the First Notice period, the Board received one
    public comment concerning
    the proposed rule.
    Citizens Utilities
    Company of Illinois (Citizens)
    filed a comment on April
    24, 1987,
    which requested that the Board’s proposed rule include wastewater
    treatment works of investor owned utilities.
    That is, Citizens
    would like privately owned treatment facilities to qualify for
    a
    lagoon exemption if it has an untreated waste load between 2500
    and 5000 population equivalents.
    The proposed rule applies only
    to a publicly owned treatment works
    (POTW).
    The Board notes that
    Citizen’s comment merits consideration, and the Board will
    explore this issue further
    under Docket B.
    ORDER
    The Board directs that second notice of the following
    proposed rule be submitted to the Joint Committee on
    Administrative Rules:

    EFFLUENT STANDARDS
    SUBPART A:
    GENERAL EFFLUENT STANDARDS
    Section 304.120
    Deoxygenating Wastes
    Except as provided
    in Section 306.103, all effluents containing
    deoxygenating wastes shall meet the following standards:
    a)
    No effluent shall exceed
    30 mg/i of five day biochemical
    oxygen demand
    (BODç)
    (STORET number 00310) or
    30 mg/i of
    suspended solids (~TORETnumber 00530),
    except that
    treatment works employing three stage lagoon treatment
    systems which are properly designed, maintained and
    operated, and whose effluent has a dilution ratio no
    less than five to one or who qualify for exceptions
    under paragraph
    (c)
    shall not exceed 37 mg/i of
    suspended solids.
    b)
    No effluent from any source whose untreated waste load
    is 10,000 population equivalents or more,
    or from any
    source discharging into the Chicago River System or
    into
    the Calumet River System,
    shall exceed 20 mg/i or BOD5
    or 25 mg/i of suspended solids.
    c)
    No effluent whose dilution ratio is less than five
    to
    one shall exceed 10 mg/i of BODç or
    12 mg/l of suspended
    solids,
    except that sources employing third—stage
    treatment lagoons shall
    be exempt from this paragraph
    (c)
    provided all of the following conditions are met:

    The waste source qualifies under one of the
    following categories:
    ~j
    Any wastewater treatment works whose untreated
    waste load
    is less than 2500 population
    equivalents and
    is sufficiently isolated that
    combining with other sources
    to aggregate 2500
    population equivalents or more is not
    practicable.
    ~j
    Any publicly owned
    treatment works
    in
    existence on January
    1,
    1986 whose untreated
    waste load is 5000 population equivalents
    or
    less and sufficiently isolated that combining
    to aggregate 5000 population equivalents or
    more
    is not practicable.
    C)
    Any publicly owned treatment works whose
    untreated waste load
    is 5000 population
    equivalents or less which has reached the end
    7g~344
    3
    of its useful life by January
    1,
    1987 and
    is
    sufficiently isolated that combining to
    aggregate 5000 population equivalents or more
    is not practicable.

    The lagoons are properly constructed, maintained
    and operated; and
    43)
    The deoxygenating constituents of the effluent do
    not, alone or
    in combination with other sources,
    cause a violation of the applicable dissolved
    oxygen water quality standard.
    d)
    No effluent discharged
    to the Lake Michigan basin shall
    exceed 4 mg/i of BOD5
    or
    5 mg/i of suspended solids.
    e)
    Compliance with the numerical standards in this Section
    shall be determined on the basis of the type and
    frequency of sampling prescribed by the NPDES permit for
    the discharge at the time of monitoring.
