    OPINION
    AND
    ORDER OF THE BOARD
    (by Mr. Henss):
    Amoco Chemicals Corporation filed its Petition for Variance
    requesting
    an extension of a variance previously granted in
    PC]3
    73—401 and extended in PCB 74—123.
    Specifically, Anioco seeks
    relief from Rule 205(g)
    (organic material emissions)
    of
    the Air
    Pollution Control Regulations until May 31,
    1975.
    Petitioner operates a multi-purpose chemical additive
    manufacturing facility at its refinery in Wood River,
    Illinois.
    This facility produces 13 additives used in motor oil, diesel
    lubricating oil,
    fuel oils and specialty oil.
    During production
    of the additives,
    waste materials including organic materials
    subject
    to Rule
    205(g) are produced.
    Hydrocarbons are emitted to
    the atmosphere when a nitrogen purge is placed on reaction kettles,
    precoat mix tanks and filter precoat mix tanks.
    More detailed information on this unit’s operation,
    the
    environmental impact from such operation and control equipment
    to be installed may be found
    in the Board’s prior Opinion on this
    matter
    (?CB 73—397—401, December 20,
    1973 and PCB 74-121-123,
    June 20, 1974).
    Compliance with Rule
    205(g)
    is to be achieved in three phases:
    (1)
    the elimination of nitrogen purging of three reaction vessels,
    (2) the elimination of nitrogen purging of sixteen filter feed
    tanks, and
    (3) installation
    of
    a closed solids handling system.
    Phase
    (1) was completed in July 1974 resulting in the reduction
    of hydrocarbon emissions from 214 lbs./hr. to about 77 lbs./hr.
    expressed as equivalent methane.
    Delivery of equipment for Phase
    (2)
    16—145
    —2—
    was completed in December 1974.
    No problems~are anticipated in
    completing installation on or before expiration of the present
    variance on March
    31,
    1975.
    Completion of Phase
    (2) will further
    reduce Petitioner’s emissions to about
    23. lbs./hr.
    Eauiprnent for Phase
    (3) has been delayed by the prime con-
    tractor, the Ducon Company.
    In
    a letter dated December 9,
    1974
    Ducon advises Amoco that it should seek at least a one month
    extension of the present variance.
    It is obvious from the Petition
    for Variance that Amoco believes a one—month extension will not
    allow time for completion of Phase
    (3)
    .
    Thus, Amoco seeks
    a two—
    month extension.
    The Agency believes that delay in completing Phase
    (3)
    is
    beyond Petitioner’s control and recommends granting this variance.
    No objection to
    the grant of variance has been received by the
    Agency.
    If problems do not delay completion of Phase
    (2)
    by March
    31,
    1975, Petitioner will have reduced its total emissions of hydro-
    carbons by almost 90%.
    Petitioner has made good progress
    in
    reducing its hydrocarbon emissions and could have completed its
    compliance program on schedule if not for the delay in receiving
    equipment.
    Clearly this delay
    is beyond Petitioner’s control.
    Variance will be granted.
    ORDER
    It is the Order of the Pollution Control Board that Amoco
    Chemicals Corporation be granted variance from Rule 205(g)
    of
    the Air Pollution Control Regulations for its Wood River multi-
    additive manufacturing facility until May 31,
    1975 or such earlier
    date as Phase
    (3)
    control equipment is completed.
    This variance
    is subject to the following conditions:
    1.
    Petitioner shall apply for all required construction
    and operating permits from the Agency.
    2.
    Petitioner shall submit monthly progress reports to
    the Environmental Protection Agency.
    Such progress
    ~eports shall detail progress toward completion of
    Petitioner’s compliance plan.
    3.
    Upon delivery of equipment for Phase
    (3)
    of the
    compliance program Petitioner shall advise the Agency
    of the delivery date and the expected date of
    completion of Phase
    (3).
    4.
    Petitioner shall keep in effect the $50,000 bond
    ordered in the previous Opinion of the Board to
    guarantee installation of required air pollution
    control equipment.
