    ORDER OF THE
    BOARD
    (by B. Forcade):
    On June
    24, 1986, Mobil Chemical Company
    (“Mobil”) filed
    a
    signed certification of acceptance of conditions associated with
    the variance modification granted by the Board on May
    9, 1986.
    A
    letter
    accompanied
    the
    signed
    certification
    which
    noted
    a
    probable
    typographical
    error
    in
    the
    language
    of
    the
    order
    and
    requested clarification.
    The Board will construe this letter as
    a motion to correct
    a clerical mistake pursuant to
    35 Ill. Adm.
    Code 103.241(a).
    This motion is
    granted and the clarification
    and correction requested by Mobil
    is provided in the instant
    order.
    The error
    in question is found
    in paragraph two of the May
    9, 1986, Order where the word “optional”
    is found.
    As Mobil has
    pointed out, similar language in previous orders regarding this
    facility have used the word “optimal” which better comports with
    the Board’s ifrtent regarding this condition.
    The corrected
    language of the order granting modification of variance is
    provided, in full, below:
    The variance from 35 Ill.
    Adm.
    Code 302.121 and 302.218
    previously granted to Mobil Chemical Company (“Mobil”), DePue
    facility, for Outfall 002 on August 22, 1984,
    is hereby modified
    by the conditions established
    in this Order.
