    JAMES E. MEASON, ATTORNEY AT LAW, APPEARED ON BEHALF OF
    PETITIONER; and
    BONNIE R. SAWYER, ASSISTANT COUNSEL TO THE ILLINOIS ENVIRONMENTAL
    PROTECTION AGENCY, APPEARED ON BEHALF OF THE ILLINOIS
    ENVIRONMENTAL PROTECTION AGENCY.
    OPINION AND ORDER OF THE BOARD (by K.M. Hennessey):
    In an interim opinion and order dated December 4, 1997, the Board considered
    petitioner Louis Berkman d/b/a Swenson Spreader Company’s (Swenson) request for an
    adjusted standard from certain air regulations. The Board determined that Swenson was
    entitled to an adjusted standard and directed Swenson to file a compliance plan for that
    adjusted standard.
    Swenson has filed a compliance plan, which the Illinois Environmental Protection
    Agency (Agency) opposes and portions of which it has moved to strike. The parties have filed
    several other pleadings regarding the compliance plan that are addressed below. In this final
    opinion and order, the Board grants Swenson an adjusted standard from 35 Ill. Adm. Code
    215.204(j)(2) for its current operations beginning on May 7, 1998. The adjusted standard will
    terminate on May 7, 2008. The adjusted standard is subject to the conditions set forth in the
    order that follows this opinion.
    PROCEDURAL HISTORY
    Swenson manufactures snow and ice control equipment at a plant in Lindenwood, Ogle
    County, Illinois. Swenson applies coatings to its products. In this proceeding, Swenson seeks
    an adjusted standard from a regulation that limits the amount of volatile organic material
    (VOM) that may be contained in its coatings.
    Specifically, Section 215.204(j)(2) requires that Swenson use coatings that contain no
    more than 3.5 pounds of VOM per gallon (VOM lb./gal.). Swenson claims that not all of the
    coatings that it must use can meet this limit. Petition Narrative (Nar.) at 2. Although Part
    215 provides several alternatives to complying with this limit, Swenson believes that the cost

    2
    of these alternatives is unreasonable. Nar. at 10; see 35 Ill. Adm. Code 215.205(b),
    215.206(a)(1).
    For the first year after the grant of the adjusted standard, Swenson requests an adjusted
    standard that would allow it to use coatings that contain, on a monthly average, 5.0 VOM
    lb./gal. Thereafter, Swenson requests an adjusted standard that would allow it to use coatings
    that contain, on a monthly average, 4.75 VOM lb./gal. Nar. at 49. The Agency opposes
    Swenson’s request.
    1
    Board Hearing Officer Deborah Frank Feinen held hearings in this case on April 25,
    1997, and June 3, 1997.
    2
    No members of the public attended either hearing. In accordance
    with a Hearing Officer order, both parties filed post-hearing briefs.
    In its order of December 4, 1997, the Board made various findings of fact and
    conclusions of law that are incorporated herein by reference. In summary, the Board found
    that coatings that comply with Section 215.204(j)(2) are not available for some of Swenson’s
    customer orders. The Board also found that the cost that Swenson would incur to comply with
    the regulatory alternatives to Section 215.204(j)(2) are unreasonable. The Board concluded
    that these factors are substantially and significantly different from those that the Board
    considered when adopting Section 215.204(j)(2). The Board also concluded that an adjusted
    standard will not result in environmental or health effects substantially and significantly more
    adverse than the effects considered by the Board in adopting Section 215.204(j)(2), and that an
    adjusted standard is consistent with applicable federal law. The Board therefore found that it
    would grant Swenson an adjusted standard, with certain modifications further discussed below
    (see pp. 4-10).
    Swenson filed a proposed compliance plan (Comp. Plan) on February 3, 1998. The
    Agency responded to that plan on February 26, 1998 (Agency Resp.). Pursuant to a hearing
    officer order, Swenson filed a response to the Agency’s response on March 16, 1998 (Swenson
    Reply). The Agency filed a motion for leave to file a reply to Swenson’s response, along with
    the reply, on March 18, 1998 (Agency Surreply). In the interest of having a complete record,
    the Board grants the Agency’s motion for leave to file the Agency Surreply.
    On March 30, 1998, Swenson filed two additional pleadings: a motion for leave to file
    a response to the Agency’s Surreply (Swenson Response to Agency Surreply), and a motion
    for leave to file an amendment to the Swenson Reply (Swenson Amended Reply). The Agency
    did not file a response to either motion. The Board grants both motions.

    “Pet. Exh. __”; the Agency’s exhibits at the hearings are cited as “Resp. Exh. __.”

    3
    The Agency also moved to strike portions of the compliance plan by motion dated
    February 18, 1998 (Mot. to Strike), to which Swenson replied on February 26, 1998 (Reply to
    Mot. to Strike). The Board addresses these pleadings below.
    MOTION TO STRIKE
    The Agency moves to strike portions of Swenson’s proposed plan on several grounds.
    First, the Agency argues that in its proposed plan, Swenson has attempted to introduce new
    evidence. Mot. to Strike at 1. Specifically, the Agency argues that much of the information
    on page 2 of the compliance plan regarding powder coatings was previously stricken from its
    post-hearing reply brief. Mot. to Strike at 2. The Agency also argues that Swenson has
    introduced new information about limitations on the use of powder coatings on page 2 of the
    compliance plan. Mot. to Strike at 2. The Agency argues that Swenson’s compliance plan
    was to be based on the record of the adjusted standard proceeding, and that this new
    information is in effect an amended adjusted standard petition to which the Agency may file a
    response. Mot. to Strike at 2.
    Swenson objects to the motion, arguing that there are no statutory or regulatory
    provisions limiting the information included in a company’s compliance plan, and that the
    Board’s order of December 4, 1997, imposed no limitations on the content of the compliance
    plan. Swenson also argues that its compliance plan should not be deemed an amended adjusted
    standard petition, because the Board has already determined that Swenson should be granted an
    adjusted standard. Reply to Mot. to Strike at 2. Swenson argues that it has provided complete
    information to allow the Board and the Agency to conduct a full and informed review of the
    plan. Reply to Mot. to Strike at 3.
    The Board denies the Agency’s motion to strike. The Board’s order of December 4,
    1997, did not limit the content of the proposed compliance plan. Furthermore, given that
    Swenson does not currently use a powder coating system, the information that Swenson
    provided on powder coatings is not relevant.
    Even if Swenson is allowed to present new information regarding powder coatings in
    its compliance plan, the Agency argues that the compliance plan should be stricken because it
    is in effect an amended petition that is not verified in accordance with 35 Ill. Adm. Code
    106.706. Mot. to Strike at 2. The Board does not agree, however, that the compliance plan is
    an amended adjusted standard petition. Therefore, the Board will not order Swenson to verify
    the compliance plan.
    PROPOSED COMPLIANCE PLAN
    Swenson’s proposed compliance plan describes its current coating line and the
    procedures and methods it will use to determine VOM emissions.

    4
    Coating Line Description
    Swenson states that it currently operates one 320 sq. ft. (20’ x 16’) Binks downdraft
    wet spray booth, with a 32,000 cu. ft./minute fan capacity. Comp. Plan at 3. Swenson states
    that the fan provides 100 ft./minute air velocity to meet Occupational Safety and Health
    Administration regulations. Comp. Plan at 3. Swenson uses GRACO PRO AA 4500 high
    pressure, low volume electrostatic spray guns for high solids finishing. Comp. Plan at 3.
    Procedures and Methods to Determine VOM Emissions
    Swenson proposes to calculate the average VOM emitted on a monthly basis by
    determining the total VOM in pounds delivered to the coating applicator and dividing that
    amount by the number of coating gallons used in that calendar month. Comp. Plan at 3. In
    making these calculations, Swenson will use the VOM content provided in the material safety
    data sheets that it receives from its paint suppliers. Comp. Plan at 3. Swenson will keep its
    VOM tracking records on site, and will provide those records along with its annual emissions
    report. Comp. Plan at 3.
    Swenson states that its paint personnel and paint supervisor daily track paint usage by
    the number, color, type, and size of units sprayed. Comp. Plan at 3. Paint personnel and
    supervisors provide this information to Swenson’s environmental compliance officer. Comp.
    Plan at 3. The environmental compliance officer computes the VOM emissions for each
    month, and compares these calculations with purchase records and standing inventory to ensure
    accuracy. Comp. Plan at 3.
    Swenson states that it will continue to work with wet coatings suppliers to develop low
    VOM content coatings of acceptable adherence and durability. Comp. Plan at 3-4. Swenson
    also will continue to investigate using powder coatings. Comp. Plan at 4. Swenson is willing
    to amend its proposed compliance plan by December 4, 2002, the mid-point of its ten-year
    adjusted standard. Comp. Plan at 4.
    DISCUSSION
    The Agency objects to Swenson’s proposed compliance plan on several grounds. First,
    the Agency notes that Swenson has indicated that it may use powder coatings to comply with
    the adjusted standard. Agency Resp. at 2-3. The Agency believes that the compliance plan
    must confirm, one way or the other, whether Swenson will use powder coatings. Agency
    Response at 2-3, 4. If Swenson will use powder coatings, the Agency argues that the adjusted
    standard should be revisited when Swenson begins to use powder coatings. Agency Response
    at 3. The Agency reiterates these arguments in its Surreply, and further argues that Swenson
    has engaged in a “pattern of attempts to withhold and mischaracterize information about its
    offer to use powder coating in this proceeding.” Surreply at 2. Swenson disputes this charge.
    Swenson Response to Agency Surreply at 1-2.

    5
    The Board does not agree that Swenson’s compliance plan must commit to using
    powder coatings (or to commit that it will not). While the compliance plan should address the
    possibility that Swenson may use powder coatings, no purpose would be served by requiring
    Swenson to pledge to use, or not to use, powder coatings. Swenson has consistently stated that
    it may use powder coatings, but that it will need some time to implement and test a powder
    coating system.
    Second, the Agency argues that if Swenson intends to include powder coating in its
    monthly average VOM to comply with the 4.75 VOM lb./gal. limitation, the plan does not
    propose a method to perform this calculation. Agency Resp. at 3. The Agency notes that one
    gallon of liquid coating will cover a lesser area than a gallon of powder coating. This is so,
    the Agency states, because powder coating is virtually all solids, while liquid coating is a
    combination of solids and VOM, and the VOM evaporates after it is applied. Agency Resp. at
    3. In addition, less powder coating will be used if the powder coating system recycles
    overspray. Agency Resp. at 3-4.
    In reply, Swenson argues that given that it does not have a powder coating system, and
    does not know what coatings it would use if it did, it is not possible to state how it would
    factor in powder coatings when computing its monthly average. Swenson Reply at 2.
    Swenson proposes that it amend its compliance plan to address this issue if and when it begins
    to use a powder coating system that uses a powder coating with VOM. Swenson Reply at 2.
    The Board finds Swenson’s approach generally reasonable, but finds that Swenson
    should amend its compliance plan if it begins to use a powder coating system, whether or not
    that system uses a powder coating that contains VOM. The Board believes that it is important
    for the Board and the Agency to know how powder coatings would affect Swenson’s average
    VOM emissions.
    Third, the Agency raises a number of concerns about the methods that Swenson
    proposes to use to track VOM emissions, as well as certain omissions from Swenson’s
    proposed compliance plan. The Board addresses those concerns below.
    Other Compliance Plan Issues
    Swenson’s Proposal to Track Paint Usage
    The Agency notes that Swenson proposes to use “theoretical” usage rather than
    “actual” usage in calculating its monthly average, and to check the results against purchase and
    inventory records. Agency Resp
    .
    at 5. The Agency argues that Swenson should track actual
    coating usage. Agency Resp. at 5.
    Swenson disagrees with the Agency’s claim that Swenson plans to track “theoretical”
    rather than “actual” usage. Swenson Reply at 2. Swenson claims that its method will be more
    accurate than the method the Agency has proposed because Swenson will cross-check its usage
    records against its inventory records. Swenson Reply at 2.

    6
    The Board finds Swenson’s proposal unclear. From Swenson’s description of its
    operations, it should be able to track, on a daily basis, the total VOM in pounds delivered to
    the coating applicator and the amount of coating, in gallons, used each day. The Board’s
    order will include a requirement that Swenson do so. The order also will require Swenson to
    maintain these records on site for three years and to make them available for Agency
    inspection during regular business hours. In addition, Swenson must provide the Agency with
    a summary report on its average monthly VOM emissions on an annual basis beginning on
    May 7, 1999.
    The Agency noted that the Board’s order did not make it clear whether the monthly
    average that Swenson calculates should be a cross-line average. The Board notes that Swenson
    has only one coating booth now, so cross-line averaging is not currently an issue. It was the
    Board’s intent that Swenson calculate its monthly VOM average for all of its coating
    operations, and the order will so provide. As later explained, if Swenson changes its processes
    in a way that affects its VOM emissions, Swenson must apply for a modified adjusted
    standard.
    Swenson’s Use of Thinners
     
    In addition, the Agency notes that Swenson’s plan does not indicate if Swenson adds
    thinners to coatings before applying the coatings, and if so, how it will account for such
    thinners in calculating the total pounds of VOM delivered to the coating applicator. Agency
    Response at 5.
     
    Swenson replies that its calculations will include any solvents (
    i.e.
    , thinners) added to
    coatings. Swenson Reply at 2. The compliance plan that the Board orders requires Swenson
    to include any solvents or thinners added to coatings when it calculates its VOM emissions.
     
    Exclusion of Water from Swenson’s VOM Calculation
    The Agency notes that Swenson has not clarified whether it will exclude water and
    other exempt compounds in calculating VOM lb./gal., as 35 Ill. Adm. Code 215.204 requires.
    In the Swenson Reply, Swenson states that it will exclude water and any other compounds
    exempted from the regulation’s definition of VOM. Swenson Reply at 3. The compliance
    plan that the Board orders requires Swenson to exclude water and other compounds exempted
    from the definition of VOM when it calculates its VOM emissions.
    Swenson’s Reliance on Material Safety Data Sheets for VOM Content
    The Agency objects to Swenson’s plan to obtain data on the VOM content of its
    coatings from the material safety data sheets (MSDS) provided by each coating supplier. The
    Agency argues that this data is acceptable only if the coating supplier determined VOM content
    in accordance with Method 24, 40 CFR Part 60. Agency Resp. at 5-6. The Agency notes that
    Method 24 is a United States Environmental Protection Agency (USEPA) standard and that the

    7
    USEPA may require it as a prerequisite to approving this adjusted standard as a state
    implementation plan revision. Agency Resp. at 5-6.
    Swenson argues that it is not its burden to demonstrate compliance with 35 Ill. Adm.
    Code 215.208. Swenson Reply at 3. While the regulation provides that “[t]he VOM content
    of coatings shall be determined by Method 24,” it does not specify who must determine that
    content. Swenson Reply at 3. Swenson argues that it is not in a position to dictate to coating
    suppliers how to test their products, although Swenson is willing to encourage its suppliers to
    use Method 24, if they do not do so already. Swenson Reply at 3. Swenson further argues
    that industries across the United States rely on MSDSs, and that it should be allowed to do so
    barring information impeaching the integrity of a particular MSDS. Swenson Reply at 3.
    In the Swenson Amended Reply, Swenson argues that it has learned that the Agency is
    interpreting Section 215.208 differently than it has previously interpreted 35 Ill. Adm.
    218.105(a)(2), a regulation which also requires the used of Method 24. Swenson Amended
    Reply at 2. Swenson argues that in a stipulation and settlement entered in People v. Dynaweld
    (March 7, 1996), PCB 96-127, the Agency stipulated that “Dynaweld was informed, by a
    representative of the Agency, that MSDS[s] submitted by Dynaweld with its application to
    renew its operating permit . . . were sufficient to demonstrate compliance with 35 Ill. Adm.
    Code 218.105(a).” People v. Dynaweld, PCB 96-127, Stipulation and Settlement at 13. The
    Agency went on to maintain, however, that a condition in Dynaweld’s operating permit
    required it to test each coating as applied under Method 24, in accordance with 35 Ill. Adm.
    Code 218.105(a). Dynaweld, PCB 96-127, Stipulation and Settlement at 13.
    From this, Swenson draws the inference that Dynaweld was required to use Method 24
    only because of the condition in its operating permit, not because it is required in Section
    218.105(a)(2). Swenson Amended Reply at 2. Swenson then argues that because Section
    215.208 is “substantively the same” as Section 218.105(a)(2), Section 215.208 must be
    interpreted similarly. Swenson Amended Reply at 2. Finally, Swenson cites various federal
    and state cases for the proposition that an agency may not change a practice or custom with
    respect to its interpretation of an ambiguous rule. Swenson Amended Reply at 2.
    The Board finds Swenson’s arguments unpersuasive. The Board is reluctant to draw a
    conclusion about the Agency’s “custom and practice” on the basis of a few statements in a
    single stipulation and settlement that addresses a different regulation. Furthermore, it is far
    from clear that the inferences that Swenson draws from the Dynaweld stipulation are correct;
    other interpretations certainly are possible. In any event, it is important to remember that this
    is an adjusted standard proceeding, in which the Agency is free to propose that Swenson use
    Method 24 as a condition of this adjusted standard whether or not Illinois’ regulations require
    that method.
    The Board finds that Swenson should use Method 24 to determine the VOM content of
    its coatings. The Board found that method appropriate when it adopted Section 215.208, and
    similarly finds it an appropriate condition on Swenson’s adjusted standard. See 415 ILCS
    5/28.1 (1996) (in granting an adjusted standard, the Board may “impose such conditions as

    8
    may be necessary to accomplish the purposes of this Act.”). If its coating suppliers can
    provide records to Swenson that demonstrate that the coating supplier determined VOM
    content under Method 24, Swenson need not re-test the coatings, although it must maintain a
    copy of the records that the coating supplier has provided on site for three years. If Swenson
    tests the coatings itself, it must maintain those records on site for three years. In either case,
    Swenson must make these records available for Agency inspection during regular business
    hours.
    Swenson’s Records
    The Agency notes that Swenson appears to propose that it will maintain records of
    coating usage on an aggregate basis. The Agency argues that unless Swenson maintains
    records of usage on a coating-by-coating basis, it will be difficult for the Agency to verify
    compliance. Agency Response at 6.
    Swenson did not address this concern in the Swenson Reply. While it is not clear that
    Swenson did propose to maintain records on an aggregate basis, the Board agrees that it would
    be difficult for the Agency to verify compliance if Swenson did so. Accordingly, the
    compliance plan that the Board orders requires Swenson to maintain records on a coating-by-
    coating basis.
     
    Swenson’s Dip Tank
    The Agency notes that Swenson’s compliance plan fails to mention the dip tank that it
    uses at its facility. Tr.1 at 181. The Agency argues that the compliance plan must account for
    any coatings and thinners used in Swenson’s dip tank. Tr.1 at 6. In the Swenson Reply,
    Swenson states that it no longer operates or maintains a dip tank. Swenson Reply at 3. The
    Board finds that given that the compliance plan will require Swenson to calculate its average
    monthly VOM emissions on for all coating operations, the compliance plan need not address
    whether Swenson uses a dip tank.
     
    Requiring Swenson to Continue to Make Efforts to Comply with Section 215.204(j)(2)
    Finally, the Agency argues that the compliance plan should require Swenson to:
    maintain contact with coating vendors regarding the availability of coatings that comply with
    Section 215.204(j)(2) (compliant coatings); submit annual reports to the Agency detailing
    Swenson’s efforts to find compliant coatings; re-evaluate the adjusted standard if Swenson is
    able to meet a limit lower than the adjusted standard by 15% or more; report to the Agency on
    Swenson’s research into and use of powder coatings; withdraw its adjusted standard if
    Swenson’s emissions are and will continue to be 80% or less of 25 tons per year based on
    current production and orders. Agency Resp. at 7-8.
    In the Swenson Reply, Swenson argues that these requirements are overly burdensome
    and serve no legitimate purpose. Swenson Reply at 4. Swenson argues that even with a
    powder coating system, its emissions will be near the upper limit of the adjusted standard.

    9
    Swenson Reply at 4. Swenson states that it will keep abreast of developments in the coatings
    industry out of necessity. Swenson Reply at 4.
    The Board finds that the compliance plan should require Swenson to undertake, with
    some modifications, the efforts that the Agency suggests. These measures are similar to those
    that the Board has imposed upon others who have received adjusted standards or site-specific
    standards. For example, the Board required Roadmaster Corporation and DMI, Inc. to contact
    at least three coating vendors per year to determine if compliant coatings were available. See
    Petition of DMI, Inc. for Site-Specific Air Regulations, 35 Ill. Adm. Code 215.215 (February
    6, 1992), R91-9 (DMI), slip op. at 5-6; Site-Specific Petition of Roadmaster Corporation
    (April 26, 1990), R88-19 (Roadmaster), slip op. at 2-3. Similarly, the Board required Solar to
    “continue its research and development efforts regarding solvents-based adhesives . . . .” See
    Joint Petition of Solar Corporation and the Illinois Environmental Protection Agency for
    Adjusted Standards from 35 Ill. Adm. Code 218, Subpart PP (July 20, 1995), AS 94-2, slip
    op. at 11. The Board also required DMI and Roadmaster to report to the Agency on their
    efforts on an annual basis. DMI, R91-9, slip op. at 5, Roadmaster, R88-19, slip op. at 4.
    Accordingly, the Board finds it reasonable to require Swenson to maintain contact with at least
    three coating vendors each year regarding the availability of compliant coatings, and to report
    these contacts to the Agency on an annual basis. Swenson also must test any compliant
    coatings that these vendors provide, as well as any compliant coatings that the Agency
    identifies to Swenson in writing, and must include the results of these tests in its annual report
    to the Agency. In a similar vein, the Board believes it reasonable for Swenson to include in an
    annual report the status of its research on powder coatings.
    In addition, the Agency requests that Swenson re-evaluate the adjusted standard if
    Swenson is able to meet a limit lower than the adjusted standard by 15% or more, and
    withdraw the adjusted standard if Swenson’s emissions are and will continue to be 80% or less
    of 25 tons per year based on current production and orders. Agency Response at 7-8. The
    Board finds these requirements are somewhat duplicative and potentially unworkable. Instead
    of imposing these requirements, the Board will follow the same approach it did regarding DMI
    and Roadmaster: if Swenson’s research shows that it can technically and economically use
    compliant coatings, or a powder coating system, Swenson must propose a plan to switch to
    such coatings or to a powder coating system. Furthermore, Swenson must move for a
    modification of its adjusted standard if it modifies its processes in a way that affect its VOM
    emissions, including if Swenson begins to use a powder coating system.
    The Board emphasizes that Swenson has several options if it objects to the conditions that
    the Board has placed on this adjusted standard. First, under the Board’s procedural rules,
    Swenson may move the Board to reconsider the conditions that the Board has placed on this
    adjusted standard. Second, Swenson may appeal the Board’s adjusted standard to the Illinois
    Appellate Court. (Of course, the Agency also may move that the Board reconsider this order or
    may appeal this order.) Third, Swenson may choose to comply with the rule of general
    applicability --
    i.e.
    , 35 Ill. Adm. Code 215.204(j)(2) -- in lieu of the adjusted standard. In Citizens
    Utilities v. Pollution Control Board, 9 Ill. App. 3d 158, 164, 289 N.E.2d 642, 647 (2
    nd
    Dist.
    1972), the Illinois Appellate Court held that a petitioner who is granted a variance upon

    10
    conditions retains the option of complying with the rule of general applicability in lieu of the
    variance. The same logic applies in an adjusted standard proceeding and therefore Swenson has
    the same option.
    CONCLUSION
    The Board grants Swenson an adjusted standard from 35 Ill. Adm. Code 215.204(j)(2)
    for its current operations beginning on May 7, 1998. The adjusted standard will terminate on
    May 7, 2008. The adjusted standard is subject to the conditions set forth in the following
    order.
    ORDER
    1. The Board grants Swenson a ten-year adjusted standard from 35 Ill. Adm. Code
    215.204(j)(2) beginning on May 7, 1998 and ending on May 7, 2008. Under this adjusted
    standard, Swenson must not cause or allow the emission of volatile organic material
    (VOM) from its coating operations at its facility in Lindenwood, Ogle County, Illinois, to
    exceed a monthly average of 4.75 pounds of VOM per gallon of coating (VOM lb./gal.).
     
    2. The adjusted standard is subject to the following conditions:
     
    a. Swenson must maintain records, on a daily basis, of the amount of VOM, in
    pounds, that it delivers to each coating applicator each day and the amount of
    coatings, in gallons, it uses each day. Swenson must maintain these records on site,
    on a coating-by-coating basis, for three years. Swenson must make these records
    available for Agency inspection during regular business hours.
     
    b. Swenson must calculate the monthly average VOM emissions on the basis of the
    total amount of VOM (including VOM in solvents, thinners, or other materials
    added to coatings) delivered to its coating applicators each calendar month and the
    total amount of coatings used in that calendar month. In calculating this average,
    Swenson must exclude water and any compounds that are specifically exempted
    from the definition of VOM, as specified in 35 Ill. Adm. Code 215.204. Swenson
    must provide the Agency with a summary report on its average monthly VOM
    emissions, in lb./gal., on an annual basis beginning on May 7, 1999.
     
    c. In determining its VOM emissions, Swenson must use the VOM content of coatings
    as determined in accordance with Method 24, 40 CFR Part 60. Swenson must
    maintain records demonstrating the VOM content of its coatings, as determined by
    Swenson or its coating suppliers in accordance with Method 24, 40 CFR Part 60,
    on site at its facility for three years. Swenson must make these records available
    for Agency inspection during regular business hours.
     
    d. Swenson must maintain contact with at least three paint vendors a year regarding
    the availability of coatings that comply with 35 Ill. Adm. Code 215.204(j)(2), and

    11
    must provide a written report to the Agency of these contacts annually beginning on
    May 7, 1999. Swenson must test any compliant coatings that these vendors
    provide, as well as any compliant coatings that the Agency identifies in writing to
    Swenson, and must include the results of these tests in an annual written report to
    the Agency. Swenson also must discuss in this report the status of its research into
    the use of powder coatings.
     
    2.
    Swenson must apply to the Board to withdraw this adjusted standard if its research
    shows that Swenson can technically and economically use coatings that comply with 35
    Ill. Adm. Code 215.204(j)(2) or a powder coating system.
     
    3.
    Swenson must apply to the Board to modify this adjusted standard if Swenson modifies
    its production processes in a manner than affects its VOM emissions (including, but not
    limited to, the use of a powder coating system).
    IT IS SO ORDERED.
    Section 41 of the Environmental Protection Act (415 ILCS 5/41 (1996)) 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 7th day of May 1998 by a vote of 7-0.
    Dorothy M. Gunn, Clerk
    Illinois Pollution Control Board
