    OPINION
    AND
    ORDER
    OF
    THE
    BOARD
    (by
    J. Theodore Meyer):
    This matter is before the Board on petitioner TRW, Inc.’s
    amended petition for variance,
    filed on December 21,
    1993.’
    TRW
    seeks a variance from 35 Ill. Adm. Code 215.301 “Use of Organic
    Material”.
    The Illinois Environmental Protection Agency (Agency)
    filed its recommendation on June 20,
    1994, recommending that the
    requested variance be granted, subject to conditions.
    A public
    hearing was held before hearing officer Deborah L. Frank on
    September 7,
    1994,
    in Marshall, Illinois.
    No members of the
    public attended the hearing.
    BACKGROUND
    TRW’S Transportation Electronics Division manufactures
    automotive electronic devices at its facility in Marshall, Clark
    County,
    Illinois.
    Approximately 80
    of the manufacturing at the
    Marshall facility is the production of air bag system diagnostic
    modules
    (ASDM)
    for Chrysler, Toyota, and Saab.
    The rest of the
    manufacturing is for customers such as Caterpillar and General
    Motors.
    The Marshall facility employs approximately 570 full
    time and 112 temporary employees, and has an annual payroll of
    $13.3 million.
    (Pet. at 7.)
    As part of its manufacturing process, TRW uses a conformal
    coating process to coat the circuit boards used in the ASDM.
    This coating prevents moisture and dirt from collecting on the
    circuit boards.
    (Pet.
    at 3; Tr. at 14.)
    The coating material is
    TRW filed its original petition for variance on October
    22,
    1993.

    2
    comprised of toluene, methyl ethyl ketone, and solids.
    The
    circuit boards are dipped in the coating material, and then
    exposed to a heating element which evaporates the solvent.
    (Tr.
    at 14.)
    RELIEF REQUESTED
    TRW seeks a variance from 35 Ill.
    Adin. Code 215.301, which
    establishes an emission limit of
    8 lbs/hr of organic material.
    Under maximum production, TRW estimates that the conformal
    coating process emits up to 5325 pounds per week (approximately
    45 pounds per hour)
    of volatile organic materials
    (VOM).
    According to the Agency, when TRW began this manufacturing
    process it was in compliance with Section 215.301 because the
    coating operation emitted less than
    8 lbs/hr.
    However, the
    Agency states that due to the increased demand for air bags, TRW
    is not presently in compliance with Section 215.301.
    (Rec.
    at
    4.)
    TRW seeks a variance from Section 215.301 to allow it an
    opportunity to investigate compliance options.
    (Pet. at 4.)
    In
    its amended petition, TRW requested a variance of up to 30
    months.
    (Pet.
    at 1.)
    However, the Agency has recommended that
    the requested variance expire on September 30,
    1995
    (Rec.
    at 9),
    and TRW indicated at hearing that it is committed to achieving
    compliance by that date
    (Tr.
    at 23).
    ENVIRONMENTAL IMPACT
    TRW’S Marshall facility is located in Clark County, which is
    characterized as attainment for ozone.
    (Pet. at 17.)
    TRW states
    that there were no recorded exceedences of the ozone air quality
    standard at the two nearest monitoring stations2 during 1992,
    which registered highest readings of 78—85
    of the ozone
    standard.
    Based on those results, TRW believes that emissions
    from its Marshall facility will not have a significant effect
    upon the air monitoring results.
    (Pet.
    at 11,
    17.)
    TRW also
    modeled emissions from the coating operation using a USEPA-
    approved air dispersion model, and further notes that it has not
    received any odor or air quality complaints about the facility.
    Thus, TRW concludes that the risk of any adverse effect upon the
    environment or human health caused by the grant of variance will
    be minimal.
    (Pet.
    at 16—18.)
    The Agency agrees that there were no recorded exceedences of
    the ozone standard during 1992; however, the Agency states that
    the increase in TRW’s production may not have fully occurred
    until after that period.
    The Agency states that the same two
    2
    The nearest monitoring stations are located in
    Champaign,
    90 miles northwest of Marshall, and Effingham,
    55
    miles southwest of Marshall.

    3
    monitors
    (Champaign and Effingham) did not record an exceedence
    in 1993.
    (Rec. at 7.)
    Additionally, the Agency believes that
    the issuance of a variance to TRW may have an environmental
    impact in the Chicago ozone nonattainment area,
    since Clark
    County is located upwind of the Chicago area.
    (Rec.
    at 7.)
    The
    Agency notes that background emissions contribute significantly
    to the ozone problems in the Chicago area,
    and states that it is
    particularly concerned given the requirement that Illinois reduce
    emissions of VOM in the Chicago area by 15
    by 1996.
    (Rec.
    at
    8.)
    COMPLIANCE
    PLAN
    TRW
    states
    that,
    with
    the
    help
    of
    its
    consultants,
    it
    is
    evaluating various air pollution control systems to reduce
    emissions to the required level.
    TRW considered, and rejected,
    condensation and flaring, and is continuing to evaluate carbon
    adsorption,
    thermal oxidation, catalytic oxidation,
    and solvent
    scrubbing.
    (Pet.
    at 14.)
    Installed capital costs for these
    options range from $200,000 to $600,000, with annual operating
    costs between $8,000 to $200,000 per year.
    (Pet.
    at 15.)
    TRW is
    also evaluating alternative coating processes.
    A revised process
    would reduce emissions at the source, and not require the capture
    and treatment of emissions.
    (Pet.
    at 14;
    Tr. at 23.)
    Mark
    Desmarais, manager of manufacturing engineering at the Marshall
    facility, testified at hearing that TRW has identified an
    alternative coating process, and that preliminary testing
    indicates that the alternative process meets all specifications.
    (Tr. at 16.)
    Mr. Desmarais testified that the process is now
    being tested to qualify the results with all of TRW’S customers,
    which can only be done by running the customer’s product in the
    plant.
    (Tr. at 16-17.)
    TRW has indicated that it will continue
    to explore alternative control equipment,
    so that it can comply
    with the emission limits if the alternative coating process
    is
    ultimately unsuccessful.
    (Tr. at 25—26.)
    HARDSHIP
    TRW states that the conformal coating process is a critical
    step in its production processes,
    and that restricting or
    temporarily suspending the coating process would,
    in effect,
    completely shut down the Marshall facility.
    In addition to the
    700 employees who would be out of work, TRW maintains that its
    inability to produce electronic devices for companies such as
    Chrysler, Toyota,
    Saab,
    General Motors, and Caterpillar would
    have a significant effect on automobile and hearing equipment
    manufacturing operations.
    TRW notes that it
    is the sole supplier
    of air bag system diagnostic modules for Chrysler.
    (Pet.
    at 24.)
    TRW concludes that compliance with Section 215.301 would impose
    an arbitrary and unreasonable hardship upon TRW.
    (Pet.
    at
    1.)
    The Agency states that “En)otwithstanding the environmental

    4
    impact,
    in deference to the facility’s concerns with achieving
    the limits set forth in the Act
    tsic) and maintaining customer
    satisfaction, the Agency agrees that requiring
    TRW
    to comply
    before it has had an opportunity to evaluate the situation fully
    would cause an unreasonable hardship.”
    (Rec.
    at 8.)
    CONSISTENCY WITH FEDERAL
    LAW
    TRW states that emissions from its Marshall facility are not
    expected to violate air quality standards, and that prevention of
    significant deterioration
    (PSD)
    regulations do not apply.
    TRW
    further states that there are no applicable new source
    performance standards (NSPS)
    or national emissions standards for
    hazardous air pollutants (NESHAPs).
    Thus, TRW concludes that the
    requested variance is consistent with those federal requirements.
    (Pet. at 26.)
    The Agency states only that because Part 215 has been
    approved by USEPA as part of the Illinois state implementation
    plan (SIP), the variance,
    if granted, will need to be submitted
    to USEPA as a SIP revision.
    (Rec. at 8-9.)
    CONCLUSIONS
    After reviewing the record and the panes’
    arguments, the
    Board finds that immediate compliance with 35 Ill. Adm. Code
    215.301 would impose an arbitrary or unreasonable hardship on
    TRW.
    The record demonstrates that TRW’s emissions have a minimal
    impact in the immediate area, and that immediate compliance with
    the emission limitation would require a shut—down of the Marshall
    facility.
    Therefore, the Board will grant a variance until
    September 30, 1995 from Section 215.301 for.TRW’s Marshall
    facility, subject to conditions.
    We are concerned with the possibility that TRW’S emissions
    might adversely impact on the Chicago ozone nonattainment area.
    However, the variance is for a relatively short time period, and
    will cover one ozone “season”
    (i.e. April to October 1995).
    We
    expect that TRW will strictly comply with all timeframes in the
    variance, and attain compliance by the September 30, 1995
    expiration of this variance.
    This opinion constitutes the Board’s findings of fact and
    conclusions of law.
