    ORDER OF THE BOARD
    (by J.C. Marlin):
    This matter comes before the Board on receipt of an Agency
    Recommendation dated September
    11,
    1991.
    The recommendation
    refers to a request from Petitioner,
    General Motors Corp.,
    for a
    provisional variance from the oils,
    fats,
    and greases and
    suspended solids
    (TSS)
    effluent requirements,
    as set forth
    in 35
    Ill.
    Adm. Code 304.124 and from provisions of the variance
    granted in PCB 83-30,
    for the period from when the Petitioner
    begins removes its skimmer/sedimentation tank or retention basin
    from service,
    and continuing until the Petitioner completes an
    enlarged retention basin, but not for longer than 45 days.
    The Agency recommends that the Board grant the requested
    provisional variance with specified conditions.
    The Agency
    agrees that the repairs are necessary.
    The Agency anticipates
    that the requested provisional variance would have minimal
    environmental impact on the receiving stream.
    The Agency is
    unaware of any public water supplies that the requested
    provisional variance would adversely impact.
    The Agency
    maintains that a grant of
    a provisional variance would violate no
    federal laws.
    The Agency finds that a denial of the requested
    provisional variance would create an arbitrary and unreasonable
    hardship on the Petitioner.
    The responsibilities of the Agency and the Board
    in these
    short—term provisional variances are different from the
    responsibilities
    in standard variances..
    See Ill. Rev.
    Stat.
    1989,
    ch.
    111½,
    pars.
    1035(b)
    &
    (c).
    In provisional variances it
    is the responsibility of the Agency to make the technical
    determinations and finding of arbitrary or unreasonable hardship.
    The Board’s responsibility is to adopt a formal Order, to assure
    the formal maintenance of the record, to assure the
    enforceability of the variance, and to provide notification of
    the action by a press release.
    Having received the Agency recommendation finding that a
    denial of the requested relief would impose an arbitrary and
    unreasonable hardship, the Board hereby grants Petitioner
    a
    provisional variance from 35
    Ill.
    Adm. Code 204.124 and
    126—101
    2
    paragraphs 45(a),
    45(i),
    45(1) (1) ,45(i) (2), and 45(1) (3) to the
    extent they pertain to suspended solids,
    on the following
    conditions:
    1.
    The term of this provisional variance shall commence
    when the Petitioner, General Motors Corp., removes its
    skimmer/sedimentation tank or retention basin from service,
    and it shall expire on the date the Petitioner completes
    construction of an enlarged retention basin,
    or after
    45
    days have elapsed, whichever comes first;
    2.
    During the term of this provisional variance, the
    effluent from the Petitioner’s treatment plant shall not
    exceed concentrations of 75 mg/l TSS
    (monthly average
    basis);
    3.
    The Petitioner shall notify Steve Baldwin of the
    Agency’s Champaign Regional office by telephone,
    at 217-
    333-8361, when it removes its skimmer/sedimentation tan k or
    retention basin from service and when the new retention
    basin is completed,
    and the Petitioner shall confirm this
    notice in writing within five days,
    addressed as follows:

    The Petitioner shall perform the necessary construction
    work as expeditiously as possible to minimize the period of
    time discharge will occur; and

    Acceptance of this provisional variance and forward that
    copy to the Agency addressed as
