    ORDER OF THE
    BOARD
    (by J.C. Narlin):
    This matter comes before the Board on receipt of an Agency
    Recommendation dated October
    9,
    1991.
    The recommendation refers
    to a request from Petitioner, USX Corporation, for a provisional
    variance from the total residual halogen
    (TRH)
    requirements, as
    set forth in 35
    Ill. Adm. Code 302.208(d)
    and 304.141(b),
    for the
    period from when the Petitioner begins initiation of its zebra
    mussel eradication program,
    and continuing for a period of 45
    days,
    or until the Petitioner’s modified permit is issued in
    final form, whichever occurs first.
    The Agency recommends that the Board grant the requested
    provisional variance with specified conditions.
    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 302.208(d)
    and
    304.141(b),
    on the following conditions:
    126—505
