    OPINION AND ORDER OF THE BOARD
    (by Mr. Henss)
    Petitioner Mattison Machine Works requests extension of
    a
    variance
    with
    respect to applicable emission standards for the
    operation of its cupola.
    We
    granted the variance on February
    3,
    1972 and at the same time ordered Mattison to pay a penalty of
    $3500 and post a performance bond in the amount of $160,000 to
    guarantee installation and performance of a cupola emission
    control
    system.
    The variance was to expire August 31, 1972 or
    sixty days
    after final delivery of all equipment necessary for
    installation of the emission control system, whichever first
    occurred.
    Installation of the system has not progressed as rapidly as
    anticipated.
    The delay was caused by late delivery of equipment
    to Mattison by the supplier.
    The Environmental Protection Agency
    inspected the site on August 24, 1972 and found that all major
    pieces of equipment which had been delivered were assembled.
    It
    was said that all items were operable except for the primary
    blower which was expected to be completed within
    a few days.
    Baghouse bags had not yet been received although the delivery
    had been promised for May
    1,
    1972.
    Delivery of the bags was
    expected by September
    15,
    1972.
    On the date of inspection the
    only work remaining to be done was installation of bags,
    installation
    of shaker motors and connection of the cyclone collection exhaust to
    the
    baghouse.
    In an attempt
    to comply with the August
    31,
    1972 deadline it was
    Petitioner~sintention to temporarily operate the emission control
    system without the baghouse.
    The supplier had represented to
    Mattison that the
    system,
    even without the baghouse, would result
    in
    80 percent collection of cupola emissions.
    Petitioner therefore
    calculated that its emissions would comply with regulations
    as of
    6—111
    —2—
    startup.
    The Agency had no way of verifying the accuracy of
    the claim that
    80 percent efficiency would be achieved on startup--
    but using figures from a 1971 stack test did agree that if an
    80
    percent collection were achieved the emissions would be less than
    the allowable 23.75 pounds per hour.
    Whatever the exact percentage
    of efficiency may he,
    it seems clear that operation of the system
    prior to installation of the complete baghouse will mean
    a sub-
    stantial reduction of emissions.
    Petitioner has made good progress and is not at fault in the
    delayed completion of the baghouse.
    It seems reasonable
    to us
    that Mattison should not bear the risk of
    a possible violation
    pending completion of the baghouse and the necessary testing to
    determine compliance.
    Therefore, we grant the extension of
    variance subject to appropriate conditions.
    ORDER
    It
    is ordered that:
    1.
    The variance granted Petitioner on February
    3,
    1972
    is extended through December 15, 1972 or sixty days
    after final delivery to Mattison of all equipment
    necessary for installation of the cupola emission
    control system, whichever first occurs.
    2.
    Continued operation of Petitioner’s facility during
    the period of the variance shall he controlled with
    all available control equipment.
    3.
    Petitioner
    shall review the information in its
    installation permit application,
    and,
    if
    nucessary,
    apply for a revised permit.
    4.
    Petitioner shall inform the Environmental Protection
    Agency in writing when bags are received for its
    baghouse and when installation of
    the baghouse is
    complete.
    5.
    Petitioner shall comply with all requirements of
    Rule 103 of Chapter
    2, Part
    1 of
    the
    Pollution
    Control Board Regulations.
    All applicable conditions
    of
    the Board’s Order
    in PCB 71-277 shall be continued
    in effect.
    6.
    The
    Bond
    filed
    with
    the
    Environmental
    Protection
    Agency under Condition
    3 of the Board’s Order in
    PCB 71-277 shall be continued in effect and amended
    to insure compliance with the Order of the Board
    entered
    in
    this
    case.
