    ORDER OF THE BOARD
    (by D. Satchell):
    This matter comes before the Board upon a variance petition
    filed October 29,
    1980 by Central Illinois Public Service Company
    (CIPS).
    The petition requests for the Grand Tower Power Station
    in Jackson County an extension of a variance previously granted
    from the effluent standards for copper (total),
    iron
    (total)
    and
    iron
    (dissolved)
    of Rule 408(a)
    of Chapter
    3:
    Water Pollution,
    for discharges of boiler chemical cleaning rinse water into the
    ash pond.
    On December
    3, 1980 the Illinois Environmental Protec-
    tion Agency
    (Agency)
    recommended that the variance be granted with
    conditions.
    No hearing was held and no public comment has been
    received.
    The
    Board has previously granted a variance from the copper
    and
    iron effluent standards for boiler cleaning rinse water from
    the Grand Tower Power Station
    (CIPS v.
    IEPA, PCB 80—20,
    38 PCB
    43,
    April
    3,
    1980;
    38 PCB 277, May 15, 1980).
    The record, Opinion and
    Orders
    are incorporated into this proceeding by reference.
    That
    variance expired November 30, 1980, by which time CIPS had expected
    to complete its boiler cleaning.
    Boiler No.
    9
    (Unit No.
    3) was
    cleaned according to schedule.
    However, CIPS was
    unable
    to clean
    boilers Nos.
    7 and
    8
    (Unit No.
    3)
    during the scheduled shutdown
    period due to delays in completing the retubing of condensers for
    Unit
    No.
    3.
    CIPS now expects to complete the boiler cleaning on
    or before December 31, 1980.
    CIPS proposes to clean its boiler Units by filling them with
    EDTA (ethylenediaminetetraacetic acid),
    a chelating agent.
    CIPS
    will haul by tanker truck the spent EDTA solution containing most
    of the metal waste for treatment away from the site.
    It will then
    be necessary to rinse the boiler tubes.
    Because of the volume of
    rinse water
    it is
    not practicable to haul it away.
    CIPS proposes
    to discharge to the ash pond the rinse water only.
    40—20 1
    —2—
    Because there
    is less than two weeks remaining before December
    31, 1980 the Board will grant the variance through December 31,
    1981 in order to avoid the possible necessity of a further ex-
    tension.
    Conditions of the variance will allow only a single
    cleaning of each boiler during the period of this variance.
    The Board finds that CIPS would suffer arbitrary or unreason-~
    able hardship if this variance were denied for substantially the
    same reasons set forth in the Board’s previous Opinion in PCB 80-20.
    The
    variance is granted with the conditions set forth below.
    This Opinion constitutes the Board1s findings of fact and
    conclusions of law in this matter.
