    OPINION AND ORDER OF THE BOARD
    (by B. Forcade):
    This matter
    is before the Board
    on the December
    2,
    1988
    petition (“Petition”)
    of Monsanto Company
    (“Monsanto”)
    for
    a
    variance from
    35 Iii. Adm. Code
    215.966.
    Such variance would
    i-elate
    to Monsanto’s emissions of volatile organic materials
    (“VOM”)
    from
    it p—dichlorobenzene
    (“PDCB”) flaking/block process
    at
    Sauget.,
    St. Clair County, Illinois.
    The Illinois
    Environmental Protection Agency
    (“Agency”) filed
    its variance
    recommendation (“Agency Recommendation”)
    on January 18,
    1989,
    urging the Board
    to grant
    the variance with conditions.
    The
    public hearing occurred February 10, 1989 at Sauget,
    Illinois.
    No member
    of the public attended.
    R.
    31.
    Background
    Monsanto produces,
    inter
    alia, chlorinated
    benzenes at
    its
    W.G.
    Krumrnrich
    plant
    at Sauget,
    IllinoIs.
    This proceeding
    directly
    involves Monsanto’s PDCB flaking/block process at that
    plant.
    The W.G.
    Krummrich plant
    is
    a major source of employment
    and revenue
    in the
    area.
    Monsanto has two domestic (outside
    Illinois)
    and five foreign competitors
    in PDCB production.
    Monsanto employs
    41 persons
    in
    its PDCB flaking/block process.
    R.
    21—23;
    Ex.
    9.
    PDCB
    is
    a co—product of benzene chlorination, together with
    o-dichlorobenzene
    (“ODCB”)
    and chlorobenzene
    (“MCB”).
    Following
    chlorination, PDCB and ODCB are first separated from MCB,
    then
    PDCB
    is refined
    by separation from ODCB.
    In the PDCB
    flaking/block process, PDCB
    is molded into 24—pound blocks of
    high purity product.
    These are prepared
    for shipment as blocks
    (plastic wrapped on pallets)
    further processed
    for shipment
    as
    crushed material
    (in 55—pound bags)
    or
    a bulk liquid
    (in railcars
    or semi—trailers).
    PDCB
    is
    a solid
    at room temperature,
    but
    it
    readily
    sublimates
    to
    a vapor.
    R.
    10—11;
    Ex.

    97—193

    —2—
    Monsanto has identified six VOM emissions sources
    in its
    PDCB flaking/block process
    (sources numbered 120,
    130,
    104,
    105,
    107, and 109).
    The aggregated VOM emissions
    from these sources
    is 476 tons per year:
    460 tons
    of PDCB,
    14 tons of ODCB,
    and 2
    tons
    of MCB.
    R.

    & 11—12; Ex.

    St. Clair County
    is
    in
    a
    non—attainment area for ozone
    (Metropolitan St. Louis Interstate
    Air Quality Control Region).
    See
    40 CFR 81.18 & 81.314 (1987).
    The nearest ozone monitor,
    in East St. Louis,
    Illinois, has
    registered one ozone excursion since
    1986.
    Monsanto’s VOM emissions are not subject
    to regulation until
    April
    1,
    1989.
    Monsanto must
    then achieve
    an overall reduction
    of 81 percent
    of
    its uncontrolled VOM emissions.
    35
    Ill. Mm.
    Code 215.966
    (1988)
    (adopted at
    12
    Ill.
    Reg.
    7284,
    7335
    (Apr.
    22,
    1988), effective Apr.
    8,
    1988).
    To achieve compliance, Monsanto
    could install activated carbon controls
    at an initial capital
    cost
    of $1,500,000 and an annual operating cost
    of $7,000,000.
    The installation
    of
    these controls would first achieve compliance
    in March
    1990.
    The only means by which Monsanto could achieve
    immediate compliance,
    by the April
    1,
    1989 effective date
    of
    Section 215.966,
    is
    to shut down its PDCB flaking/block pro-
    cess.
    Instead, Monsanto desires
    to install
    a new PDCB crystalli-
    zation process
    that would achieve
    a 99.8 percent reduction
    of its
    uncontrolled VOM emissions by March 31,
    1990*.
    Monsanto
    commenced work on this new process
    in January 1988.
    It would
    result
    in overall annual VOM emissions
    of 1.1 tons from the PDCB
    process
    (the subject of the requested variance)
    and about 2.5
    tons from its overall
    chlorinated benzene process.

    Discussion
    The Board
    finds
    that a PDCB flaking/block process shutdown,
    directed towards achieving
    immediate compliance with
    35
    Ill. Mm.
    Code 215.966, could impose an unreasonable hardship on
    Monsanto.
    Monsanto maintains that a process shutdown,
    in order
    to achieve compliance
    by April
    1,
    1989, would impose an arbitrary
    and unreasonable hardship.
    It would result
    in direct financial
    losses,
    irreparable losses
    of business,
    and direct and indirect
    losses of
    jobs.
    Petition at 12—13;
    Ex.
    9 at
    4
    The Agency agrees
    that
    a plant shutdown
    to achieve
    immediate compliance
    is
    “economically unreasonable.”
    Agency Recommendation
    at
    3.
    *
    In its December
    2,
    1988 petition, Monsanto projected
    a June
    1990 completion
    date
    for
    this project and requested
    a variance
    until July
    1,
    1990.
    Petition at
    8
    & 15.
    The Agency disagreed
    with these dates, Agency Recommendation at 3—4, and Monsanto
    revised
    them to March
    30,
    1990.
    Ex.
    9 at
    5.
    97—194

    —3—
    The record indicates that the requested variance offers the
    more viable means of achieving greater environmental benefits
    than are possible with add—on controls.
    Monsanto maintains
    that
    the installation of activated carbon controls would ultimately
    achieve
    a lesser reduction
    in VO~4emissions than is possible with
    the new PDCB process.
    The addition of
    such add—on controls would
    constitute
    a substantial cost, and these controls would not
    achieve compliance
    at an earlier date than
    is possible with the
    new PDCB crystallization process.
    Petition at 11—12;
    Ex.
    6.
    The
    Agency agrees that the date upon which compliance
    is possible
    with activated carbon controls
    is
    “not significantly different
    than the proposed plan.”
    Agency Recommendation at
    3.
    The Board
    finds
    that employing activated carbon controls on the existing
    flaking/block process would not result
    in the same degree of VOM
    emissions reduction as
    is possible with the hew crystallization
    process.
    The Board also finds
    that such add—on controls would
    not likely achieve compliance at
    a materially earlier date than
    the proposed new process would allow.
    The record further
    indicates secondary environmental
    benefits would
    arise through Monsanto’s proposed variance
    compliance plan.
    Monsanto asserts
    that its new PDCB
    crystallization process would eliminate
    25
    to 40 tons of
    dichlorobenzerie from its wastewater effluents each year.
    R.
    14;
    Ex.
    8 at
    5.
    The Board believes that
    this secondary environmental
    benefit
    is desirable.
    The record supports a conclusion that the requested relief
    is consistent with federal
    law.
    Monsanto and the Agency both
    observe
    that Monsanto’s PDCB flaking/block process VOM emissions
    will
    initially become subject to regulatory control
    under
    35
    Ill.
    Mm.
    Code Part 215 on April
    1,
    1989.
    Petition at 10—11; Agency
    Recommendation at
    2.
    The U.S. Environmental Protection Agency
    (“USEPA”) has not yet approved the proposed State Implementation
    Plan
    (“SIP”)
    revision
    for new (April
    1988) Section 215.966.
    Monsanto and the Agency agree
    that the proposed variance
    is not
    inconsistent with
    federal law,
    although
    it might require
    a SIP
    revision
    if the USEPA approves the pending Section 215.966
    revision before
    this variance action
    is final.
    Petition at
    13;
    Agency Recommendation
    at
    2.
    The record also supports
    a conclusion
    that
    a grant
    of
    variance will not adversely affect ambient air quality.
    Monsanto
    commits itself
    to maximum VOM emission rates of 483
    tons per year
    for all its refined dichlorobenzene sources
    and 476 tons per year
    for those sources involved
    in this proceeding during
    the term of
    the variance.
    MonsaRto maintains
    that these VOM emissions
    “will
    not cause any additional environmental
    impacts beyond the current
    operation,
    ...“
    and highlights
    the lowered emissions
    rates
    after
    installation of the new PDCB crystallization process.
    Petition
    at
    9.
    The Agency believes
    that during the variance term
    “Monsanto’s emissions should not cause any violations of the
    97--195

    —4—
    National
    Ambient
    Air
    Quality
    Standard
    for
    ozone).”
    Agency
    Recommendation
    at
    2.
    The
    Agency
    recommends
    a
    grant
    of
    the
    requested
    variance
    from
    Section 215.966, with certain conditions.
    R.
    31; Agency Recom-
    mendation at
    4.
    First, the Agency would
    limit the term of
    variance
    to
    the
    period
    from
    April
    1,
    1989
    to
    March
    31,
    1990.
    Second,
    the
    Agency
    maintains
    that
    the
    information
    Monsanto
    has
    presented
    is
    inadequate to determine if Monsanto will achieve
    broader compliance with
    35
    Ill. Mm. Code 215. Subpart RR.
    Other
    sources
    in the plant,
    not mentioned in Monsanto’s petition,
    are
    subject to
    this rule.
    The Agency recommends
    that Monsanto
    certify
    that
    all
    sources
    subject
    to Subpart RP (Sections 215.960
    through
    215.966)
    will
    comply
    by
    the
    end
    of
    the
    variance
    term.
    Finally,
    the
    Agency
    recommends
    that
    Monsanto submit quarterly
    progress reports
    as
    a condition of the variance.
    Agency
    Recommendation at
    3—4.
    Monsanto
    is willing to accept these three
    conditions.
    R.
    5
    &
    26—27;
    Ex.
    9
    at
    5.
    For
    the
    foregoing
    reasons,
    the
    Board
    will
    grant
    Monsanto
    the
    requested
    variance
    from
    Section
    215.966
    with
    the
    Agency—
    recommended conditions.
    The variance term will
    run from April
    1,
    1989
    through
    March
    31,
    1990.
    Monsanto
    shall
    certify
    compliance
    with
    35
    Ill.
    Adm.
    Code
    215.
    Subpart
    RR
    by
    March
    31,
    1990
    for
    all
    sources
    at
    its
    plant
    that
    are
    subject
    to
    this
    Subpart,
    including
    those
    sources
    not
    part
    of
    this
    proceeding.
    Monsanto
    shall
    submit
    quarterly
    Subpart
    BR
    compliance
    progress
    reports
    to
    the
    Agency
    for
    all
    sources
    within its plant, beginning with
    the first
    calendar
    quarter
    of
    1989
    and ending after
    the first calendar
    quarter of
    1990.
    Other Matters
    The Board’s Opinion and Order of
    December
    15, 1988
    in the
    companion trade secrets docket, PCB 88—194 Docket
    A,
    included the
    following language:
    The
    Board
    determines
    the
    claimed
    items
    of
    information
    are
    subject
    to
    protection
    as
    confidential
    information.
    The
    Board
    will
    protect
    this information pursuant to Part
    120,
    Subpart
    C
    of
    Title
    35
    of
    the Illinois Admini-
    strative
    Code,
    until
    ...
    such
    a
    time
    as
    PCB
    88—19413 proceeding has terminated and Monsanto
    has requested
    the return
    of all copies
    of
    the
    variance
    petition
    containing
    the
    subject
    information.,
    Also,
    Monsanto submitted
    a vial
    of PDCB
    crystals at hearing
    as “Petitioner’s Exhibit No.
    3.”
    This type of exhibit does not
    reduce
    to paper and microfiche
    for ultimate record reduction and
    storage.
    Such physical exhibits therefore present
    a storage and
    97—196

    —5—
    maintenance difficulty for the Board.
    The Board did not rely on
    the
    confidential
    information
    or
    the
    physical
    exhibit
    fortoday’s
    decision.
    The
    Board
    directs
    Monsanto
    to
    reclaim
    from
    the
    Clerk
    of
    the
    Board
    the
    confidential
    information
    and
    physical
    Exhibit
    No.
    3,
    within 45 days,
    unless this matter
    is appealed.
    The Board
    directs
    the Clerk
    to execute appropriate documentation verifying
    the
    return
    of
    the
    materials
    to
    Monsanto.
    The foregoing constitutes
    the Board’s findings of
    fact and
    conclusions of law
    in this matter.
