    PETITIONER FORD MOTOR COMPANY; and
    DEBORAH J. WILLIAMS APPEARED ON BEHALF OF THE ILLINOIS ENVIRONMENTAL
    PROTECTION AGENCY.
    OPINION AND ORDER OF THE BOARD (by M. McFawn):
    Before the Board is a petition for an adjusted standard filed by Ford Motor Company (Ford).
    Ford seeks an adjusted standard under 35 Ill. Adm. Code 218.986, which sets emissions reduction
    requirements for miscellaneous sources of volatile organic material (VOM). The adjusted standard
    Ford seeks would enable it to implement an alternative emissions control plan for solvent clean-up
    operations at its Chicago assembly plant. The Board finds that Ford has met the requirements for an
    adjusted standard and grants the petition.
    FACTUAL BACKGROUND AND PROCEDURAL HISTORY
    1
    Ford operates an automobile assembly plant in Chicago. Pet. at 3. A body shop assembles
    vehicle bodies using stampings, frames, low VOM adhesives and welding operations.
    Id.
    The vehicle
    body is then conveyed into a paint shop where the body is run through the following: a cleaning and
    chemical coating process, electrodeposition coating (which is oven-dried), application of sealers to
    seams and areas the vehicle body, prime coating (which is oven-dried), and top coating (which is oven-
    dried). Pet. at 3-4. The painting operation uses automated paint application equipment and high solids
    paint. Pet. at 3. Automated application equipment cannot reach all areas of the vehicle body, however;
    some areas must be painted manually by workers using hand held applicators. Pet. at 5.
    Clean-up operations of various types are an integral part of Ford’s process. Vehicle bodies
    pick up oils, grease and dust due to employee contact, ambient air, equipment contact and materials
    used in manufacturing. Pet. at 4. Due to the high quality finishes demanded by Ford’s customers,
    1
    Facts set forth in this section of the Board’s opinion are taken from Ford’s petition, which was
    supported by an affidavit of John Baguzis, or from hearing testimony.

    2
    solvent clean-up operations are vital to Ford’s operations.
    Id.
    Also, inherent in the paint operation is
    the need to clean up facility components associated with that operation.
    Id.
    Eight specific clean-up
    operations are addressed in Ford’s petition:
    1.
    Booth Wall Cleaning: Uncured paint builds up on spray booth walls due to overspray,
    and must be removed to prevent it from falling onto a vehicle body and marring the
    finish. Pet. at 4; Pet. App. 2 at 1.
    2.
    Booth Grate Cleaning and Floor Cleaning: Overspray also results in uncured paint
    building up on the floor grates of the spray booths. This paint interferes with worker
    mobility in the booths, and gets tracked outside the booths. Pet. at 4-5; Pet. App. 2 at
    2, 4.
    3.
    Manual Section Paint Application Hose Cleaning: Uncured paint builds up over time on
    hoses used in manual application of paint. This causes the hoses to stick to workers’
    gloves and clothing, interfering with the paint application process. Pet. at 5; Pet. App. 2
    at 3.
    4.
    Automated Section Paint Application Equipment Cleaning: Uncured paint builds up on
    automated application equipment. This can cause equipment failure or defects in
    finishes if built-up uncured paint falls onto a vehicle body. Pet. at 5; Pet. App. 2 at 3-4.
    5.
    Purge System: Purging of paint applicators is required for every change of color, to
    avoid mixing colors. In any event, purging is necessary after every 5 or 6 vehicles
    painted in order to prevent blemishes due to soiled applicator tips. Purging involves
    blowing out paint with air followed by cleansing with a solvent. Pet. at 5; Pet. App. 2 at
    5.
    6.
    Ultra Filter Cleaning: The electrodeposition coating (e-coating) operation is a series of
    dip tanks where a coating is cathodically applied to the vehicle body. A series of rinse
    tanks follow to remove any excess material carried over from the process. The rinse
    material is reused after being cycled through an ultra filter to remove pigment and resin
    that is carried over from the e-coating process. Periodically, the filter must be cleaned
    to maintain its efficiency. Pet. at 5-6; Pet. App. 2 at 5-6.
    7.
    Paint Supply System Cleaning: Each paint color has at least one dedicated closed loop
    paint supply system for main enamel and guidecoat paint systems. Paint flows
    continuously from a circulating tank to the paint booths and is returned to the circulating
    tank. Periodically, the circulating system requires cleaning to maintain proper circulation
    or when a new color is added. Pet. at 6; Pet. App. 2 at 6-7.
    8.
    Vehicle Body Cleaning: At various points in the painting process, vehicle body wiping is
    required to prevent paint imperfections. Most such work is performed manually with
    rags and solvents. Pet. at 6; Pet. App. 2 at 7-8.

    3
    On June 29, 1990, the United States Environmental Protection Agency (USEPA) promulgated
    a Federal Implementation Plan (FIP), codified at 40 C.F.R. § 52.741 and effective July 1, 1991, for
    certain sources of VOM in the Chicago ozone non-attainment area. To cure deficiencies in its State
    Implementation Plan (SIP), Illinois adopted rules substantially identical to the FIP rules.

    Deficiencies in the Chicago Area: Amendments to 35 Ill. Adm. Code Part 215 and the Addition of Part
    218 (July 25, 1991), R91-7 (final order adopting rules). Among the regulations adopted in rulemaking
    R91-7 was 35 Ill. Adm. Code 218. Section 218.986, which is derived from 40 C.F.R. § 52.741(x),
    provides in relevant part:
    Every owner or operator of an emission unit subject to this Subpart [TT] shall comply
    with the requirements of subsection (a), (b), (c), (d), or (e) below.
    a)
    Emission capture and control equipment which achieves an overall reduction in
    uncontrolled VOM emissions of at least 81 percent from each emission unit, or
    * * *
    c)
    An equivalent alternative control plan which has been approved by the Agency
    and the USEPA in federally enforceable permit or as a SIP revision.
    (Subsections (b), (d) and (e) are not applicable to the activities involved here.)
    On September 3, 1993, USEPA issued a notice of violation to Ford, alleging that the Chicago
    Assembly Plant had failed to comply with the requirements of the FIP. Pet. at 14. Ultimately, an interim
    compliance plan was incorporated as part of a federal consent decree entered on February 10, 1998.
    See Pet. Exh. 2. By this adjusted standard petition, Ford seeks State approval of the interim compliance
    plan. Pet. at 15.
    In the course of negotiations with USEPA and the Illinois Environmental Protection Agency
    (IEPA) over a compliance plan to address Ford’s solvent clean-up operations, Ford performed a
    Reasonably Available Control Technology (RACT) study at the Chicago Assembly Plant. Pet. at 14.
    Ford evaluated three separate technologies to meet the capture and control requirement of Section
    218.986(a): an afterburner, carbon adsorpers, and a carbon wheel concentrator followed by an
    afterburner system. Pet. at 7. Ford determined that the afterburner alone could not meet the 81%
    capture and control requirement from a technical perspective. Pet. at 8. Carbon adsorpers were
    rejected because their use would have resulted in creation of a hazardous waste.
    Id
    . The carbon
    wheel/afterburner system was capable of producing the required 81% emissions reduction, but only at
    an approximate annualized cost of $45,500 per ton, with total capital investment of $16.2 million and an
    annual operating cost of $4.75 million. Pet. at 9. Ford thus concluded that the carbon
    wheel/afterburner system was cost prohibitive.
    Id.

    4
    Ford also evaluated other possible means of reducing emissions, in an attempt to develop an
    “equivalent alternative control plan” that would result in compliance under Section 218.986(c).
    Although Ford implemented several work practice and material change measures to reduce VOM
    emissions from solvent cleaning operations, Ford encountered issues such as worker safety, potential
    damage to equipment and to final product, and general non-feasibility for some of the materials and
    practices examined. Pet. at 10, Exh. 1 App. 2. The measures Ford was able to implement did not
    result in the necessary 81% reduction. Pet. at 10. Ford asserts that no other “equivalent” compliance
    plan is available.
    Id.
    USEPA specifically acknowledged that Ford’s compliance plan will result in the
    greatest reduction of emissions possible using economically and technologically feasible emissions
    controls. Pet. Exh. 2 at 16-17.
    Ford filed its petition for an adjusted standard on October 6, 1999. Notice of the petition was
    published in the
    Chicago Tribune
    on October 18, 1999. On November 30, 1999, the IEPA filed its
    recommendation, recommending that the Board grant Ford’s petition, with one additional condition
    discussed below. A hearing was held on January 27, 2000, before Board Hearing Officer Amy Muran
    Felton. One witness, Christopher Romaine, testified at the hearing on behalf of the IEPA. The parties
    waived filing of post-hearing briefs. The hearing officer set a public comment deadline of February 22,
    2000. No public comments were received by the Board.
    STATUTORY AND REGULATORY FRAMEWORK
    The Board’s authority to grant adjusted standards derives from Section 28.1 of the Illinois
    Environmental Protection Act (Act), 415 ILCS 5/28.1 (1998). Section 28.1(a) provides that a
    petitioner may request, and the Board may impose, a standard different from that which would
    otherwise apply to the petitioner as the consequence of the operation of a rule of general applicability.
    The criteria for granting an adjusted standard are set forth in Section 28.1(c), which provides:
    c.
    If a regulation of general applicability does not specify a level of justification
    required of a petitioner to qualify for an adjusted standard, the Board may grant
    individual adjusted standards whenever the Board determines, upon adequate
    proof by the petitioner, that:
    1.
    factors relating to that petitioner are substantially and significantly
    different from the factors relied upon by the Board in adopting the
    general regulation applicable to the petitioner;
    2.
    the existence of those factors justifies an adjusted standard;
    3.
    the requested standard will not result in environmental or health effects
    substantially and significantly more adverse than the effects considered
    by the Board in adopting the rule of general applicability; and
    4.
    the adjusted standard is consistent with any applicable federal law. 415
    ILCS 5/28.1(c) (1998).

    5
    DISCUSSION
    Criteria for Grant of Adjusted Standard
    Ford seeks an adjusted standard from 35 Ill. Adm. Code 218.986. Because Section 218.986
    does not specify a different level of justification for an adjusted standard, the Board evaluates Ford’s
    petition using the criteria listed in Section 28.1(c).
    Significantly Different Factors
    Subpart TT of 35 Ill. Adm. Code 218, which contains Section 218.986, applies to VOM
    sources with certain characteristics which are not governed by other subparts of Part 218. The Board
    in adopting Subpart TT did not consider factors relating to any specific industry or practice; the purpose
    of that subpart was to cover sources that had not been specifically considered. Thus, the factors
    relating to Ford’s cleaning operations were not considered by the Board when it adopted Section
    218.986. The first requirement of Section 28.1(c) is therefore met.
    Justification for Adjusted Standard
    According to Ford’s evidence, reducing emissions to the level at which compliance with Section
    218.986 would be achieved would cost approximately $45,500 per ton of reduction. This far exceeds
    the level at which the Board has generally found emissions reduction not economically reasonable. See
    In re
    Petition of Louis Berkman Co. (December 4, 1997), AS 97-5,
    aff’d sub nom
    Environmental
    Protection Agency v. Pollution Control Board, 308 Ill. App. 3d 741, 721 N.E.2d 723 (2d Dist. 1999)
    (costs of reducing emissions found to be unreasonable where they substantially exceeded $1,734 per
    ton). The Board also notes that the intent of the regulations promulgated under Part 218 is to implement
    RACT for VOM sources in the Chicago ozone non-attainment area. See
    In re
    RACT Deficiencies in
    the Chicago Area: Amendments to 35 Ill. Adm. Code Part 215 and the Addition of Part 218 (July 25,
    1991), R91-7. USEPA, as noted above, has acknowledged that Ford’s interim compliance plan,
    which would be implemented by this adjusted standard, would result in the greatest emissions reduction
    possible using technologically and economically feasible controls. Granting an adjusted standard in this
    case would thus be consistent with the goals of Part 218. Accordingly, the Board concludes that an
    adjusted standard is justified in this case.
    Environmental or Health Effects
    Subpart TT does not include an emissions cap; as long as a source complies with the 81%
    reduction requirement, Subpart TT places no restriction on total emissions. In its requested adjusted
    standard, however, Ford has agreed to a limit on total emissions from its clean-up operations of 390
    tons per year. Thus, while relative emissions reductions are less than Subpart TT would have required,
    total emissions are restricted. Furthermore, Ford asserts (and the IEPA does not dispute) that the
    adjusted standard it requests would have a negligible impact on air quality. The Board finds that the
    requested standard will not result in environmental or health effects substantially and significantly more
    adverse than the effects considered by the Board in adopting Subpart TT.

    6
    Consistency with Federal Law
    Section 110 of the federal Clean Air Act, 42 U.S.C. § 7410, grants individual states the
    authority to promulgate a plan for implementation, maintenance and enforcement of air quality standards,
    subject to approval by USEPA. A state may revise its SIP, again subject to USEPA approval.
    Id.
    The Agency has indicated that this adjusted standard will be submitted as a SIP revision.
    Recommendation at 19. We note that the terms of this adjusted standard have already been approved
    by USEPA in the context of the consent decree entered in the federal enforcement proceeding. Pet.
    Exh. 2. The Board finds that this criterion is satisfied..
    Conclusion
    Because the four requirements of Section 28.1(c) are met, the Board will grant Ford’s petition
    for an adjusted standard.
    Conditions on Adjusted Standard
    Ford and IEPA have agreed on a number of conditions to be placed on Ford’s adjusted
    standard, including limits on total emissions from cleaning operations and various record keeping and
    reporting requirements. The Board accepts these conditions and has incorporated them in its order,
    below.
    IEPA also asks that the Board condition its grant of an adjusted standard to Ford on
    withdrawal by Ford of a pending permit appeal, case number PCB 93-32. That case is an appeal of
    the IEPA’s denial of Ford’s application for renewal of its air operating permit for the Chicago Assembly
    Plant. The IEPA denied renewal of the permit because of Ford’s noncompliance with Subpart TT’s
    requirements with respect to its clean-up operations. The IEPA asserts that the issues in the permit
    appeal will be resolved by the issuance of an adjusted standard. At the hearing Ford’s counsel
    represented that Ford would withdraw the permit appeal, but asked that it not be required to do so until
    it receives a new permit, to prevent a gap in coverage. Tr. at 12.
    The Board will not require Ford to dismiss its permit appeal as a condition of this adjusted
    standard. Although perhaps practically connected, the two proceedings are legally distinct. The Board
    will not, on the incomplete information before it, speculate as to whether and when Ford’s permit appeal
    will be rendered moot. If subsequent events moot the pending permit appeal, and Ford does not
    voluntarily withdraw the appeal, IEPA can seek dismissal by motion.
    CONCLUSION
    For the foregoing reasons, the Board grants Ford an adjusted standard from 35 Ill. Adm. Code
    218.986, in the form set forth below. This opinion constitutes the Board’s findings of fact and
    conclusions of law in this matter.

    7
    ORDER
    Ford Motor Company (Ford) is hereby granted an adjusted standard from 35 Ill. Adm. Code
    218.986 insofar as that regulation applies to volatile organic material (VOM) emissions from Ford’s
    solvent clean-up operations listed below, subject to the following conditions and terms:
    1.
    Applicability. The provisions of this adjusted standard apply to the following clean-up
    operations at the Ford’s Chicago Assembly Plant (the facility):
    a.
    Paint booth wall/grate and paint floor cleaning operations;
    b.
    Automated paint application cleaning (external);
    c.
    Manual paint application equipment and associated hoses;
    d.
    Floor cleaning;
    e.
    Purge system for automated paint application equipment;
    f.
    Ultra filter cleaning and paint supply system cleaning; and
    g.
    Vehicle body cleaning.
    2.
    Emission Control Requirements.
    a.
    Emissions of VOM from the cleaning operations may not exceed 390 tons per
    year as calculated on a 12 month rolling basis.
    b.
    The facility may not use spray equipment to apply any cleaning solvent
    containing in excess of 3.5 pounds VOM per gallon (minus water and exempt
    compounds) for cleaning paint booth walls, grates, or the exteriors of paint
    application equipment.
    c.
    The facility may not utilize VOM-containing materials to remove paint from
    paint booth grates. This restriction does not prohibit the use of VOM-
    containing grate coatings which reduce adhesion of uncured paint to grate
    surfaces.
    d.
    The facility may not store waste solvent or soiled rags from cleaning operations
    in open containers when not in use except as necessary to prevent a fire hazard.
    3.
    Record Keeping and Reporting.
    a.
    For each VOM-containing material utilized in a cleaning operation, the facility
    must record the following information on a monthly basis:

    8
    i.
    The name and identification of the VOM-containing material;
    ii.
    A listing of the operations in which the VOM-containing material was
    used;
    iii.
    The pounds of VOM per gallon of the VOM-containing material,
    calculated using 40 C.F.R. 60, Appendix A, Method 24 (incorporated
    by reference at 35 Ill. Adm. Code 218.112(d));
    iv.
    The total gallons of VOM-containing material used; and
    v.
    The total gallons of solvent recovered for disposal as calculated in
    accordance with paragraph (c) below.
    b.
    The facility must also record the following facility-wide information on a monthly
    basis:
    i.
    The monthly calculated usage of VOM from each cleaning material used
    in each operation specified in section (1) above;
    ii.
    The monthly calculated emissions of VOM utilizing the information in
    subparagraph (i) above, and VOM credit as calculated in accordance
    with paragraph (c) below; and
    iii.
    The 12 month rolling total of VOM emissions calculated in accordance
    with paragraph (d) below.
    c.
    For each shipment of waste solvent from the purge reclaim tank to a solvent
    reclaimer, the facility must obtain the weight percent solids, weight percent
    water, density, total volume in gallons, pounds of VOM per gallon, and pounds
    of VOM credit. Ford must ensure that the solvent reclaimer utilizes USEPA
    Method 24 for determining VOM content, weight percent solids, weight
    percent water, and density.
    d.
    Compliance with the emissions limit of 390 tons per year as calculated on a 12
    month rolling total basis is determined by calculating VOM emissions for the
    previous month and adding emissions for the preceding 11 months, for a 12
    month total.
    e.
    Compliance calculations for the emission limit of 390 tons per year as calculated
    on a 12 month rolling total basis must be performed within 15 days of the end of
    each month.
    f.
    By April 1 of each year, the facility must obtain from each of its cleaning
    material suppliers a listing of each VOM-containing cleaning material, its VOM

    9
    content, and the quantity of cleaning material delivered to the facility during the
    previous calendar year.
    g.
    Records required by this section must be retained at the facility, available for
    inspection by IEPA during regular business hours, for a period of three years.
    h.
    Ford must notify IEPA in writing within 15 days of finding that the total VOM
    emission limitation of 390 tons per year has been exceeded. In any such
    notification Ford must identify the suspected cause of the exceedance and any
    measures taken to prevent any future exceedance.
    4.
    Employee Awareness. Ford must make a copy of the requirements of this adjusted
    standard available to paint shop cleaning personnel and paint shop area managers.
    IT IS SO ORDERED.
    Section 41 of the Environmental Protection Act (415 ILCS 5/41 (1998)) provides for the
    appeal of final Board orders to the Illinois Appellate Court within 35 days of service of this order.
    Illinois Supreme Court Rule 335 establishes such filing requirements. See 172 Ill. 2d R. 335; see also
    35 Ill. Adm. Code 101.246, Motions for Reconsideration.
    I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, hereby certify that the above
    opinion and order was adopted on the 6th day of April 2000 by a vote of 7-0.
