    PETITIONER; and
    BONNIE SAWYER APPEARED ON BEHALF OF THE ILLINOIS ENVIRONMENTAL
    PROTECTION AGENCY.
    OPINION AND ORDER OF THE BOARD (by E.Z. Kezelis):
    This matter comes before the Board on a petition for adjusted standard filed on
    March 14, 2000, by BEMA Film Systems, Inc. (BEMA) for its printing facility located in
    Elmhurst, DuPage County, Illinois. In the petition, BEMA requests that the Board adopt an
    adjusted standard from 35 Ill. Adm. Code 218.401(a), (b), and (c), which is commonly
    referred to as the “Flexographic Printing Rule.” The adjusted standard is requested from the
    portion of the Flexographic Printing Rule which requires flexographic printers use water-
    based, compliant inks that either contain no more than 40% volatile organic material (VOM)
    by volume or contain no more than 25% VOM by volume of the volatile content of the ink.
    Alternatively, the Flexographic Printing Rule also requires that if a printer cannot use the
    compliant inks, then the printer must design and apply an approved control device to capture
    VOM emissions.
    BEMA seeks an adjusted standard because it allegedly cannot use the water-based
    compliant inks and because the cost of installing and using an approved control device
    outweighs the benefit. The Illinois Environmental Protection Agency (Agency) filed its
    recommendation on October 17, 2000, in which it recommended that the Board grant the
    adjusted standard with conditions.
    The Board’s responsibility in this matter arises from the Environmental Protection Act
    (Act) (415 ILCS 5/1
    et seq
    . (1998)). The Board is charged to “determine, define and
    implement the environmental control standards applicable in the State of Illinois” (415 ILCS
    5/5(b) (1998)) and to “grant . . . an adjusted standard for persons who can justify such an
    adjustment” (415 ILCS 5/28.1(a) (1998)).
    A hearing in this matter was held on November 13, 2000, before Board Hearing
    Officer John Knittle. The parties waived posthearing briefs and no public comments were
    received. The Board has attempted to expedite its decision in response to BEMA’s motion for

    2
    expedited ruling, which was filed on November 30, 2000. The Board finds that BEMA has
    met the requirements for an adjusted standard from the Flexographic Printing Rule found at 35
    Ill. Adm. Code 218.401(a), (b), and (c), and accordingly grants the adjusted standard with the
    conditions suggested by the Agency.
    REGULATORY HISTORY
    The regulation from which BEMA seeks an adjusted standard applies to sources with
    the potential to emit (PTE) 25 TPY or more of VOM. The original reasonably available
    control technology (RACT) regulations applied to major sources with actual VOM emissions in
    excess of 100 TPY. However, Section 182(d) of the Clean Air Act (42 USC 7401
    et seq
    .
    (1996)) requires individual states with severe ozone nonattainment areas to include all sources
    with the PTE at least 25 TPY as major sources and adopt RACT regulations applicable to those
    sources.
    1 As a result of this, the Board adopted a rule that reduced the applicability threshold
    from 100 TPY to sources with the PTE of 25 TPY or more. See Omnibus Cleanup of the
    Volatile Organic Material RACT Rules Applicable to Ozone Nonattainment Areas:
    Amendments to 35 Ill. Adm. Code 203, 211, 218 and 219 (September 9, 1993), R93-9. The
    RACT control requirements remained unchanged. BEMA is permitted to emit more than 25
    TPY and finds that it cannot comply with those control requirements.
    The specific regulation from which BEMA seeks an adjusted standard is 35 Ill. Adm.
    Code 218.401(a), (b), and (c), which was originally adopted by the Board in 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, and which provides, in pertinent part, as follows:
    a) No owner or operator of a subject flexographic, packaging rotogravure
    or publication rotogravure printing line shall apply at any time any
    coating or ink unless the VOM content does not exceed the limitation
    specified in either subsection (a)(1) or (a)(2) below. Compliance with
    this Section must be demonstrated through the applicable coating or ink
    analysis test methods and procedures specified in Section 218.105(a) of
    this Part and the recordkeeping and reporting requirements specified in
    Section 218.404(c) of this Part. As an alternative to compliance with
    this subsection, a subject printing line may meet the requirements of
    subsection (b) or (c) below.
    1)
     
    Forty percent VOM by volume of the coating and ink (minus
    water and any compounds which are specifically exempted from
    the definition of VOM), or
    2) Twenty-five percent VOM by volume of the volatile content in
    the coating and ink.
    1
    BEMA is located in DuPage County, which along with Cook, Kane, Lake, and Will Counties,
    Oswego Township in Kendall County, and Aux Sable and Goose Lake Townships in Grundy
    County, make up the Chicago-area ozone nonattainment area. See 35 Ill. Adm. Code 218.

    3
    b) No owner or operator of a subject flexographic, packaging rotogravure
    or publication rotogravure printing line shall apply coating or inks on the
    subject printing line unless the weighted average, by volume, VOM
    content of all coatings and inks as applied each day on the subject
    printing line does not exceed the limitation specified in either subsection
    (a)(1) (as determined by subsection (b)(1) or subsection (a)(2)) (as
    determined by subsection (b)(2)). Compliance with this subsection must
    be demonstrated through the applicable coating or ink analysis test
    methods and procedures specified in Section 218.105(a) of this Part and
    the recordkeeping and reporting requirements specified in Section
    218.404(d) of this Part.
     
    * * *
    c) No owner or operator of a subject flexographic, packaging rotogravure
    or publication rotogravure printing line equipped with a capture system
    and control device shall operate the subject printing line unless the owner
    or operator meets the requirements in subsection (c)(1), (c)(2), or (c)(3)
    and subsections (c)(4, (c)(5) and (c)(6) below.
    1) A carbon adsorption system is used which reduces the captured
    VOM emissions by at least 90 percent by weight, or
    2) An incineration system is used which reduces the captured VOM
    emissions by at least 90 percent by weight, or
    3) An alternative VOM emission reduction system is used which is
    demonstrated to have at least a 90 percent control device
    efficiency, approved by the Agency and approved by USEPA as a
    SIP revision, and
    4) The printing line is equipped with a capture system and control
    device that provides an overall reduction in VOM emissions of at
    least:
    A) 5 percent where a publication rotogravure printing line is
    employed, or
    B) 65 percent where a packaging rotogravure printing line is
    employed, or
    C) 60 percent where a flexographic printing line is employed,
    and
    5) The control device is equipped with the applicable monitoring
    equipment specified in Section 218.105(d)(2) of this Part and

    4
    except as provided in Section 218.105(d)(3) of this Part, the
    monitoring equipment is installed, calibrated, operated and
    maintained according to vendor specifications at all times the
    control device is in use, and
    6) The capture system and control device are operated at all times
    when the subject printing line is in operation. The owner or
    operator shall demonstrate compliance with this subsection by
    using the applicable capture system and control device test
    methods and procedures specified in Section 218.105(c) through
    Section 218.105(f) of this Part and by complying with the
    recordkeeping and reporting requirements specified in Section
    218.404(e) of this Part. 35 Ill. Adm. Code 218.401.
    BACKGROUND
    On May 17, 1999, BEMA filed a petition for variance with the Board, seeking a
    variance from the Flexographic Printing Rule found at 35 Ill. Adm. Code 218.401(a), (b), and
    (c). As a result of negotiations with the Agency, BEMA then moved to dismiss the variance
    petition on December 28, 1999. On January 6, 2000, the Board granted the motion to dismiss.
    The instant petition for adjusted standard was then filed by BEMA on March 14, 2000.
    2
    BEMA operates a flexographic printing facility (facility) located in Elmhurst, DuPage
    County, Illinois. Pet. at 4. BEMA employs 30 people and operates two central-impression,
    flexographic printing presses at the facility.
    Id
    . BEMA’s printing process involves printing
    six-color images on “high-slip” polyethylene surfaces.
    Id
    . The result is a packaging material
    that is used by BEMA’s customers for the packaging of food and consumer products such as:
    frozen meats, pasta, breads, vegetables, cookies, candies, pet supplies, grass seed, bird seed,
    hardware items, aluminum pans, medical items, car batteries, and pillows. Pet. at 4-5.
    BEMA’s customers request the “high-slip” material because it is easier to use with their high
    speed filling and sealing equipment. Pet. at 5. BEMA describes its business as a small “job-
    shop,” meaning that it contracts for short-term, smaller printing jobs, that range in length from
    a couple of hours to day long. Pet. at 4; Tr. at 17-18.
    BEMA uses inks in the printing process that are formulated with solids, pigments, and
    solvents. Pet. at 5. The solvents, which contain VOM, are added to the inks in order to
    produce an ink that runs smoothly through the printing presses and produces the sharpest
    possible printed image.
    Id
    . The solvents also allow BEMA to print on the “high-slip” film.
    Id
    . According to BEMA, the use of water to dilute the inks would not have the same result.
    Id
    .

    The petition for adjusted standard will be cited as “Pet. at __.” The Agency’s response and
    recommendation will be cited as “Resp. at __.”

    5
    BEMA currently has an Agency issued permit, which allows it to emit a maximum of
    77.4 tons per year (TPY) of VOM. Pet. at 6. BEMA’s actual emissions for 1996, 1997, and
    1998, were 30.7 TPY, 29.00 TPY, and 23.00 TPY, respectively.
    Id
    .
    As previously explained, BEMA’s printing process involves printing images on “high-
    slip” polyethylene film. Pet. at 7. BEMA’s customers request the “high-slip” film because it
    is easier for them to manipulate in their own processes.
    Id
    . BEMA’s customers also require
    the printed images appear on the outside surface of the “high-slip” film.
    Id
    . According to
    BEMA, printing on the outside surface of the film, “creates significantly different concerns
    than printing an image on the reverse side of the substrate [film] or printing with a lamination
    technique.”
    Id
    . For example, printing the image on the outside surface of the film requires
    that the printed image be “extremely durable and highly scratch-resistant” so as to avoid
    damaging the image when it comes into contact with other packages and with varying
    environmental conditions. Pet. at 8. BEMA’s customers require the outer surface printing.
    Id.
    “Reverse printing” is a technique in which the printed image is displayed on the inside
    surface of the packaging. Pet. at 8. However, because many of BEMA’s customers use the
    packaging material for food and other consumer goods, they do not want the packaged goods
    to come into contact with the inks.
    Id
    . Therefore, this is not an option for BEMA.
    Another printing technique is “lamination” which involves printing an image so that it
    is bonded between two films. Pet. at 9. Because this technique involves the use of two
    substrates, or films, there are additional costs associated with it that make the use of this
    technique cost prohibitive to BEMA’s customers.
    Id
    .
    ADJUSTED STANDARD PROCEDURE
    In both a general rulemaking and a site-specific rulemaking, the Board is required to
    take the following factors into consideration: the existing physical conditions, the character of
    the area involved, including the character of the surrounding land uses, zoning classifications,
    and the technical feasibility and economic reasonableness of measuring or reducing a particular
    type of pollution. 415 ILCS 5/27(a) (1998). The general procedures that govern an adjusted
    standard proceeding are found at Section 28.1 of the Act (415 ILCS 5/28.1 (1998)) and the
    Board’s procedural rules at 35 Ill. Adm. Code 104. Section 28.1 of the Act also requires that
    the adjusted standard procedure be consistent with Section 27(a).
    In determining whether an adjusted standard should be granted from a rule of general
    applicability, the Board must consider the factors at Section 28.1(c) of the Act (415 ILCS
    5/28.1(c) (1998)), and BEMA has the burden of proving that it has satisfied those factors,
    which are:
    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 that petitioner;

    6
    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).
    In granting an adjusted standard, the Board also has the authority to impose conditions
    that may be necessary to accomplish the purposes of the Act. 415 ILCS 5/28.1(a) (1998).
    DISCUSSION
    For the reasons set forth herein, the Board grants BEMA’s request for an adjusted
    standard from 35 Ill. Adm. Code 218.401(a), (b), and (c). The Board finds that BEMA has met
    the criteria contained in Section 28.1 of the Act (415 ILCS 5/28.1 (1998)), and is accordingly
    entitled to the relief it has requested.
    Factors Relating to BEMA are Substantially and Significantly Different
    BEMA maintains that the factors relating to it are substantially and significantly different
    than those factors considered by the Board in adopting the rule of general applicability. Pet. at
    26. BEMA states that when adopted, the Flexographic Printing Rule considered emissions from
    large flexographic printing operations that have a greater impact on air quality than the smaller
    “job shop” printers like BEMA.
    Id
    . BEMA argues that the costs of compliance with the
    Flexographic Printing Rule are so high that they are more easily absorbed by large printing
    operations. Pet. at 27. Due to its size and the type of jobs performed, BEMA’s compliance
    with the Flexographic Printing Rule is neither economically reasonable nor technically feasible.
    Id
    .
    The Agency agrees that the factors applicable to BEMA are substantially and
    significantly different from those considered by the Board when it adopted these rules. The
    Agency acknowledges that the cost of add-on control equipment to BEMA is beyond the costs
    contemplated by the Board in adopting the flexographic printing rules. Resp. at 14. The
    Agency also agrees that the use of compliant water-based inks is not currently feasible for this
    particular facility.
    Id
    .
    The Board concludes that the factors relating to BEMA are substantially and
    significantly different than those considered by the Board when it adopted the flexographic
    printing rules.
    Existence of Different Factors Justifies an Adjusted Standard

    7
    BEMA asserts that it has investigated a number of compliance options. First, it
    explains why the use of compliant water-based inks will not work for its operations. One
    problem is that the currently available water-based inks clog the ink rollers and dry to the
    consistency of concrete. Pet. at 9. In order to combat these problems, BEMA would have to
    institute time consuming and costly maintenance measures at the end of every short job that is
    run.
    Id
    . Additionally, the age of BEMA’s printers (30 years) means that they were not
    designed for use with water-based inks and mechanical components in the printers may actually
    corrode and become damaged if put into contact with water.
    Id
    . BEMA estimates that it could
    retrofit the printers with water-resistant moving parts at a cost of $100,000 per press. Pet. at
    10. Finally, the compliant water-based inks take much longer to dry on the film than the
    solvent-based inks.
    Id
    . The solvent-based inks set the image permanently in less than 0.6
    seconds, whereas the water-based inks take sometimes hours longer to dry.
    Id
    . Because of
    these problems, BEMA is unable to utilize the water-based inks and satisfy its customers. Pet.
    at 11
    .
    BEMA also investigated the possibility of installing “add-on” technologies and found
    that three technologies were potentially available to its flexographic printing processes: (1)
    carbon adsorption technology; (2) wet scrubber technology; and (3) catalytic or thermal
    oxidation (afterburner) technology. Pet. at 16. After examining each of these three options,
    BEMA determined that none of them could reasonably be utilized at its facility for the
    reduction of VOM emissions.
    Carbon adsorption is not feasible because, due to the high vapor pressure of the
    flexographic ink solvents, efficient adsorption into the carbon beds is precluded. Pet. at 16.
    Additionally, some of the chemicals in the ink solvent (such as alcohol and acetates) cannot be
    efficiently removed by the carbon adsorption process.
    Id
    . The wet scrubbers, likewise, do not
    effectively remove VOM emissions due to the high vapor pressures of the solvent-based inks.
    Pet. at 17.
    While the catalytic or thermal oxidation technology is adaptable to a process such as
    BEMA’s, this technology is prohibitively expensive, and is therefore, not economically
    reasonable for this type of operation. Pet. at 17.
    The Agency also indicates that it too has been investigating a number of different
    compliance options that may be available to BEMA. Resp. at 8. The Agency agrees with
    BEMA’s assertion that compliance with the rule of general applicability for BEMA is not
    economically reasonable or technically feasible. Resp. at 14. The Agency therefore agrees
    that the existence of different factors involving BEMA’s particular business justifies the
    requested adjusted standard.
    Adjusted Standard Will Not Result in Environmental or Health Effects Substantially and
    Significantly More Adverse
    BEMA operates a small print shop. Currently, BEMA is operating under an Agency
    issued permit that allows it to emit up to 77.4 TPY. Although no information was submitted

    8
    with regard to emissions from 1999 or 2000, the annual emissions from 1996 through 1998
    were far below the 77.4 TPY maximum. There are no schools or residential areas located in
    close proximity to the facility. Pet. at 6.
    Adjusted Standard is Consistent with Federal Law
    BEMA maintains that the granting of this adjusted standard would not violate any
    federal laws. Pet. at 25. The Clean Air Act and Illinois regulations require that BEMA
    comply with RACT.
    Id
    . The Board is empowered to determine what RACT is.
    Id
    .
    Accordingly, BEMA argues that the Board has the authority to grant the adjusted standard by
    finding that the terms of the adjusted standard are RACT for BEMA, thereby satisfying the
    federal requirements.
    Id
    . If granted, the adjusted standard would be included by the Agency
    as a rule specific to BEMA in the State Implementation Plan for Illinois.
    AGENCY RECOMMENDED CONDITIONS
    In its response to the petition for adjusted standard, the Agency recommends the Board
    grant the requested adjusted standard with specific conditions. Resp. at 18. BEMA has agreed to
    each of the conditions recommended by the Agency. Tr. at 15. The conditions fall into three
    basic categories: recordkeeping, emissions impacts, and Emissions Reduction Market System
    (ERMS), and are specified more fully in the “order” which begins below at page 9. Resp. at 15-
    17
    In its response and recommendation, the Agency also explained that it has, in conjunction
    with BEMA and others, conducted its own investigation into technically feasible and
    economically reasonable means of complying with the Flexographic Printing Rule. Resp. at 8-
    14. For example, the Agency stated that it has been working with flexographic printers on
    environmental compliance issues since early 1994. Resp. at 8. Through the Agency’s own
    investigations, they have found that the industry appears to be “going backwards rather than
    forwards for this type of printing.” Resp. at 9. The Agency refers to a fact sheet published by the
    Printers’ National Environmental Assistance Center which describes the use of water-based inks
    on film as being “similar to placing water on a newly waxed car: The water beads up and slides
    around the surface.”
    Id
    .
    The Agency also acknowledges the “harsh conditions” that must be endured by the plastic
    packaging products produced by BEMA. Resp. at 11.
    For example, some bags are to be used in freezers, and thus the ink cannot crack
    or chip under cold conditions. Others must withstand hot conditions or exposure
    to water, etc. Even under these conditions, the image printed on the substrate
    cannot crack, scratch, or smear. The image left by a solvent-based ink is more
    pliable, flexible, and durable. Water-based inks have been found to produce
    images that crack more readily than solvent-based ink images when applied to
    flexible surfaces because the image is more crystalline and brittle.
    Id
    .

    9
    The Agency concludes that the Board should grant BEMA the adjusted standard it has
    requested. Resp. at 14. The Agency agrees that the use of compliant inks is problematic for
    BEMA and that the cost of add-on equipment is beyond the cost of compliance originally
    contemplated by the Board in adopting the Flexographic Printing Rule.
    Id
    .
    CONCLUSION
    The Board finds that BEMA has provided sufficient justification for the proposed
    adjusted standard. Accordingly, the Board grants BEMA the requested adjusted standard with
    the conditions suggested by the Agency.
    ORDER
    The Board hereby adopts the following adjusted standard, pursuant to the authority of
    Section 28.1 of the Environmental Protection Act (415 ILCS 5/28.1 (1998)).
    1. This adjusted standard applies only to BEMA Film Systems, Inc.’s (BEMA) two
    existing central impression presses and only to the extent that the presses are
    being used for printing on plastic, such as polypropylene, polyester, cellophane
    and polyethylene (“high-slip”), and does not apply to any printing operations on
    other substrates.
    2. BEMA may apply any coating or ink with volatile organic material (VOM)
    content less than or equal to eighty-two (82%) percent by weight of the coating
    and ink (minus water and any compounds that are specifically exempted from the
    definition of VOM) on a monthly-weighted average basis. Compliance with this
    limitation must be demonstrated through the applicable coating and ink analysis
    test methods and procedures specified in 35 Ill. Adm. Code 218.105(a) and the
    recordkeeping requirements specified in condition (4) below.
    3. For purposes of establishing an Emissions Reduction Marketing System
    (ERMS) baseline for BEMA, its actual emissions from the appropriate
    baseline seasonal allotment period will be adjusted downward to reflect
    usage of coatings and inks containing no more than seventy-two percent
    (72%) VOM by weight of the coatings and inks (minus water and any
    compounds that are specifically exempted from the definition of VOM)
    applied.
    4. BEMA shall collect and record the following information each day for the printing
    presses subject to this adjusted standard and maintain such information at
    BEMA’s Elmhurst printing facility for a period of five years:
    A) The name and identification number of each coating and ink
    applied;
     

    10
    B) The VOM content and the weight of each coating and ink applied;
    C) The monthly-weighted average VOM content of all coating and inks
    applied.
    Any record showing violation of this adjusted standard shall be reported by
    sending a copy of such record to the Agency within 30 days following the
    occurrence of this violation.
    5. BEMA must perform (alone or in conjunction with others) three experiments each
    year, including any experiments requested by the Agency, of alternative inks to
    determine if these inks are compliant with the Flexographic Printing Rule and
    technically feasible for BEMA’s printing operations. In addition BEMA will
    experiment with substrates as suggested by the Agency. Forty-five days following
    each experiment conducted pursuant to this provision, BEMA shall report its
    findings and supporting documentation to the Agency;
    6. BEMA shall continue to investigate alternative control technologies, including
    any technologies suggested by the Agency. BEMA shall report the results of
    those investigations to the Agency within forty-five days; ink applied;
    7. Each year, in conjunction with submittal of its annual Clean Air Act Permitting
    Program (CAAPP) compliance certification or its annual emissions report, if a
    CAAPP compliance certification is not required, BEMA shall submit a report to
    the Agency describing the investigations of compliant inks and coatings, different
    substrates, and add-on control technologies it has undertaken in the previous
    calendar year and the results of these investigations;
    8. BEMA shall not operate any other printing press at its Elmhurst, Illinois, facility
    without full compliance with the requirements of the Flexographic Printing Rule
    (35 Ill. Adm. Code 218.401(a), (b), (c));
    9. This adjusted standard must be revised or withdrawn if BEMA no longer prints
    the majority of its images on “high-slip” substrates, or on the outside surface of
    the “high-slip” substrate;
    10. This adjusted standard must be revised or withdrawn if BEMA determines that
    any add-on control system is economically reasonable and technically feasible or
    if BEMA uses any add-on control system that controls VOM emissions;
    11. This adjusted standard must be revised if it becomes feasible for BEMA to use
    compliant inks and coatings for the majority of its printing operations;
    12. This adjusted standard must be withdrawn if it becomes feasible for BEMA to
    use compliant inks and coatings for all of its printing operations; and

    13. If this adjusted standard is revised or withdrawn and BEMA is a participating
    source in the ERMS program, BEMA’s ERMS baseline will be adjusted
    downward to the extent that the new or revised requirements for the two central
    impression presses subject to this adjusted standard would result in lower
    baseline emissions. If such an adjustment to BEMA’s ERMS baseline is
    required by this provision, the seasonal allotment period used in its original
    baseline determination shall be used to determine its adjusted baseline. BEMA
    must submit a CAAPP application for revised baseline, as required by this
    provision, within 60 days of final withdrawal of, or revision to this adjusted
    standard.
    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 the date 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 101.520, 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 18th day of January 2001 by a vote of 7-0.
    Dorothy M. Gunn, Clerk
