    PROTECTION AGENCY, APPEARED ON BEHALF OF RESPONDENT.
    OPINION AND ORDER OF THE BOARD (by C.A. Manning):
    This matter is before the Board on two trade secret appeals filed on May 29, 1998, by
    Devro-Teepak, Inc. (petitioner), pursuant to Part 120 of the Board’s regulations concerning the
    identification and protection of trade secrets (see 35 Ill. Adm. Code 120
    et seq
    .). Petitioner is
    appealing two final determinations of the Illinois Environmental Protection Agency (Agency)
    regarding certain trade secret articles submitted by petitioner in two separate Clean Air Act
    Permit Program (CAAPP) applications (CAAPP Permit Nos. 95120325 and 95120326).
    Petitioner claims that certain articles in its CAAPP permit applications are entitled to trade
    secret protection. The Agency disagrees with petitioner, as it asserts that the raw material
    usage and emission rate information sought by each of the CAAPP forms relevant to this
    appeal constitute emission data and is not information that can be protected as a trade secret.
    By order of June 17, 1998, the Board accepted these trade secret appeals for hearing.
    The cases were consolidated for hearing and, pursuant to the parties’ agreed motion, an
    in
    camera
    hearing was held before Board Hearing Officer Amy L. Jackson on September 22,
    1998, in Danville, Illinois. On behalf of the petitioner, the following individuals testified: (1)
    John Webster, regional regulatory affairs manager at Devro-Teepak; and (2) John Ramsey,
    manager of maintenance, environmental and quality control at Devro-Teepak’s Danville plant
    location. On behalf the Agency, the following individuals testified: (1) Pamela Irwin, an
    Agency legal investigator in the division of air pollution control’s permit section; and (2)
    Christopher Romaine, Agency manager of the new source review unit in the division of air
    pollution control’s permit section.
    Since the hearing was
    in camera
    , members of the public were not allowed to attend.
    However, the hearing officer provided a sign-in sheet for members of the public wishing to

    2
    give testimony during the hearing. No members of the public appeared to give testimony at
    the hearing. See Devro-Teepak, Inc. v. IEPA (September 25, 1998), PCB 98-160, 98-161
    (hearing officer order).
    Petitioner filed its brief on October 2, 1998. The Agency filed its response brief on
    October 13, 1998, and petitioner filed its reply brief on October 16, 1998.
    Pursuant to the rules governing trade secret matters (35 Ill. Adm. Code 120
    et seq
    .),
    the Board has kept under seal all copies of the Agency record (trade secret copies), the hearing
    transcript, exhibits, and all post-hearing briefs filed in this matter.
    The Board agrees with the Agency that certain trade secret information on appeal
    constitutes emission data. In making this finding, the Board believes that those process units
    which are regulated individually should be disclosed individually. But the Board believes that
    those process units which are regulated on a combined basis should only be disclosed on a
    combined or aggregate, rather than an individual, basis. The Board finds that for those units
    that are regulated on a combined basis, the individual, line-by-line information which was
    entered on the CAAPP forms, is a protectable trade secret. Therefore, based on a review of
    the record, the Board affirms in part and reverses in part the Agency’s denial of petitioner’s
    request for trade secret protection in both its CAAPP permit applications.
    ISSUES
    There are two issues in this proceeding. The first is whether the information in
    petitioner’s CAAPP application is “emission data.” Under Section 7(a) of the Environmental
    Protection Act (Act),
    Notwithstanding any other provision of this Title or any law to the contrary, all
    emission data reported to or otherwise obtained by the Agency . . . in connection with
    any examination, inspection or proceeding under this Act shall be available to the
    public to the extent required by the federal Clean Air Act Amendments of 1977 (P.L.
    95-95) as amended. 415 ILCS 5/7(c) (1996).
    The consequence of this provision is that to the extent that the information in
    petitioner’s CAAPP application is emission data, it must be disclosed to the public. This
    provision supersedes all other provisions of the Act, so if all of the information in petitioner's
    CAAPP application is emission data, that ends the Board’s inquiry.
    If the information in petitioner's CAAPP application is not emission data, however, the
    Board must consider Section 7(a) of the Act. That section requires that “all files, records and
    data” of the Board and the Agency “shall be open to reasonable public inspection . . . except
    for . . . information that constitutes a trade secret.” 415 ILCS 5/7(a) (1996). Therefore, the
    second issue in this case is whether the information in petitioner’s CAAPP application is a
    trade secret. If not, it must be disclosed to the public.
    The term “emission data” itself is not defined in either the Clean Air Act (CAA) or the
    Act. However, both the United States Environmental Protection Agency (USEPA) and the

    3
    Agency have promulgated regulations that define emission data. The USEPA defines
    “emission data” as information necessary to determine the amount of emissions being emitted
    by a source, what types of emissions the source is allowed to emit, and the identification of the
    source. 40 C.F.R. 2.301.
    1
    While the Agency’s promulgated rules define “emission data” as
    information described in the federal definition, the Agency’s definition is more specific in that
    it identifies the specific types of information that is considered emission data. See 2 Ill. Adm.
    Code 1827.Appendix A.
    2
    The Agency definition also provides that certain information may be
    1
    The federal rules defining “emission data” provide:
    40 C.F.R. 2.301: Special Rules Governing Certain Information Obtained Under the CAA
    (a) Definitions. For the purpose of this section:
    (2)(i) Emission data means, with reference to any source of emission
    of any substance into the air—
    (A) Information necessary to determine the identity, amount, frequency,
    concentration, or other characteristics (to the extent related to air quality) of
    any emission which has been emitted by the source (or of any pollutant
    resulting from any emission by the source), or any combination of the
    foregoing;
    (B) Information necessary to determine the identity, amount, frequency,
    concentration, or other characteristics (to the extent related to air quality) of
    the emissions which, under an applicable standard or limitation, the source
    was authorized to emit (including, to the extent necessary for such purposes,
    a description of the manner or rate of operation of the source); and
    (C) A general description of the location and/or nature of the source to the
    extent necessary to identify the source and to distinguish it from other
    sources (including, to the extent necessary for such purposes, a description
    of the device, installation, or operation constituting the source).
    (ii) Notwithstanding paragraph (a)(2)(i) of this section, the following information shall
    be considered to be emission data only to the extent necessary to allow EPA to
    disclose publicly that a source is (or is not) in compliance with an applicable
    standard or limitation, or to allow EPA to demonstrate the feasibility, practicability,
    or attainability (or lack thereof) of an existing or proposed standard or limitation:
    (A) Information concerning research, or the results of research, on any project,
    method, device or installation (or any component thereof) which was
    produced, developed, installed, and used only for research purposes; and
    (B) Information concerning any product, method, device, or installation (or any
    component thereof) designed and intended to be marketed or used
    commercially but not yet so marketed or used.
    2
    The Agency’s rules regarding “emission data” provide, at 2 Ill. Adm. Code 1827.Appendix
    A, Explanation of Emission Data:
    “Emission data” means the information as described in 40 C.F.R. 2.301(a)(2)(i) and (a)(2)(ii)
    (1983).
    1.
    Emission data includes the following items to the extent they contain
    information on the identity, amount, frequency, concentration, or other

    4
    claimed to be trade secret, if the Agency is able to provide, by alternative means, the identity,
    amount, frequency, concentration or other characteristics of any emission by an emission
    source.
    In addition, Board findings in two CAA trade secret cases shed light on the issue of
    what constitutes “emission data.” See Classic Finishing Company, Inc. v. IEPA (February 7,
    1985), PCB 84-174, and In the Matter of: Duo Fast Corporation Trade Secret Claim
    Determination (March 5, 1987), PCB 87-4. In Duo Fast, the Board found that the phrase
    “necessary to determine” in the USEPA’s definition broadens, rather than limits, what
    constitutes emission data under the CAA. In this regard, the Board found that the definition
    includes actual emission data and information necessary to calculate emission data. In Classic
    Finishing, while addressing the issue of whether emission data must be disclosed on a plant-
    wide basis or individual equipment basis, the Board found that information must be disclosed
    on the basis of the point at which a source is regulated,
    i.e
    ., whether the regulations apply to
    individual emission units or to the plant as a whole.
    BACKGROUND
    CAAPP Application
    Currently, the petitioner’s facility, located in Danville, Illinois, is operating under three
    relevant permits (see
    infra
    at 7-8). However, because of the type and quantity of air emissions
    emitted by the facility, petitioner is required to apply for new air permits, pursuant to the
    CAAPP.
    characteristics, as related to air quality, of any emission or contaminant emitted
    by an emission source:
    a) Reports and printouts produced from the Agency’s Total Air System,
    including information which has been obtained by the Agency from permit
    applications and field inspections of emission sources;
    b) Stack test reports;
    c) Quarterly and annual emission reports submitted to the Agency by emission
    sources;
    d) Malfunction reports submitted to the Agency by emission sources;
    e) Compliance status reports submitted to the Agency by emission sources;
    f) Agency field inspection reports; and
    g) Permit applications filed with the Agency.
    2. Items (a) through (g) above shall be provided to a requester in conformity with
    this Part. If the Agency is able to provide, by some other means, the identity,
    amount, frequency, concentration, or other characteristics, to the extent related
    to air quality, of any emission by an emission source, the following information
    may be claimed to be trade secret or confidential data pursuant to these rules:
    a) Trade names of source equipment owned by a submitter;
    b) Name and description of a process used by the submitter; and
    c) Type, amount and method of raw materials used in the process of the
    submitter.

    5
    This proceeding involves the trade secret protection of certain information pertaining to
    raw material usage and emission rates included in the petitioner’s CAAPP application. Section
    39.5(5)(c) of the Act requires a CAAPP permit applicant to submit a complete application
    which contains information sufficient for the Agency to evaluate the subject source and to
    determine all applicable requirements pursuant to the CAA and other underlying regulations.
    The Act authorizes the Agency to develop application forms and adopt procedural rules to
    implement the CAAPP requirements. 415 ILCS 5/39.5(5)(c), (5)(y) (1996). Accordingly, the
    Agency has adopted CAAPP procedures at 35 Ill. Adm. Code 270 and issued CAAPP
    application forms along with instructions. The information submitted in a CAAPP application
    is utilized by the Agency to issue permits that include all state and federal requirements,
    emission limitations, compliance plans, testing methods, reporting requirements and operating
    modes. 415 ILCS 5/39.5(7) (1996).
    The Illinois CAAPP also requires the Agency to make available to the public all
    documents submitted by the applicant, including the CAAPP application, with the exception of
    information entitled to confidential treatment pursuant to Section 7 of the Act. 415 ILCS
    5/39.5(5)(q) (1996). In this regard, petitioner contends that the specific information
    concerning typical and maximum raw material usage rates and the typical and maximum
    emission rates falls under the Section 7 exception.
    Sequence of Events
    Due to the air emissions emitted by the facility, petitioner was required to apply for
    CAAPP permits. On November 3, 1995, petitioner filed two separate CAAPP permit
    applications (App. No. 95120326 and App. No. 95120325), which included one for each of its
    two processes: (1) the plastic packaging process; and (2) the cellulose food casing process.
    See, generally, Ag. Rec., App. No. 95120325 and No. 95120326; see also Tr. at 6.
    3
    These
    processes are described in greater detail below. Petitioner included in the CAAPP permit
    applications, a claim and justification, pursuant to 35 Ill. Adm. Code 120.201 and 120.202,
    that certain materials in the applications were entitled to trade secret protection. Tr. at 6.
    In filing its CAAPP permit applications with what petitioner believed was trade secret
    information, petitioner took various steps to protect its trade secret information. Specifically,
    petitioner marked the trade secret information on its full application and also submitted a
    redacted copy with the complete copy to the Agency. Tr. at 47. Petitioner ensured that
    employees at its plant, who viewed the trade secret information, signed corporate secrecy

    agreements. Ag. Rec., App. No. 95120325 at 003; App. No. 95120326 at 003. Additionally,
    petitioner operates its facility with a 24-hour guard service and computerized plant entry
    system.
    Id.
    Over two years following petitioner’s filing of its CAAPP applications, on January 16,
    1998, the Agency sent petitioner, via facsimile, a draft trade secret determination letter
    concerning the plastic packaging CAAPP permit application. Ag. Rec., App. No. 95120325
    at 0157-0161. On January 21, 1998, the Agency sent petitioner, via facsimile, a draft trade
    secret determination letter concerning the cellulose food casing CAAPP permit application.
    Ag. Rec., App. No. 95120326 at 0284-0291. The Agency included in its facsimile to
    petitioner a chart of each trade secret claim and the Agency’s decision as to whether or not
    each claim was a trade secret. The Agency agreed with petitioner on some of the trade secret
    claims, yet disagreed on others. On January 30, 1998, petitioner wrote a letter responding to
    the Agency’s draft determinations. Ag. Rec., App. No. 95120325 at 0162-0164; Ag. Rec.,
    App. No. 95120326 at 0292-0294. In the letter, petitioner stated that it disagreed with the
    Agency’s draft determination that some of the information was characterized as “emissions
    information.”
    Id
    . Petitioner’s letter provided further information and argument in support of
    its position.
    Final determination letters were then issued by the Agency, on both permit
    applications, on April 24, 1998. Ag. Rec., App. No. 95120325 at 0172-0179; Ag. Rec.,
    App. No. 95120326 at 0302-0312. The letters contained attachments listing the pages, parts,
    and portions of the CAAPP permit applications that had been found to represent trade secret
    information. The Agency denied certain requests for trade secret protection, however, on the
    basis that the information on the CAAPP applications constituted emission data or information
    used to determine emissions.
    The Agency’s final determination letters varied from the January 1998 draft letters in
    that the Agency ultimately denied trade secret protection for some information which initially
    appeared on the Agency’s “draft trade secret determination letter” as deserving trade secret
    protection. Specifically, the Agency determined that some of petitioner’s requests for trade
    secret were, in fact, not trade secret material. For example, the Agency revised its final
    determination letters to exclude raw material information on line 21(a) of Form 220-CAAPP
    as trade secret material, while in the original drafts the Agency had determined line 21(a) was
    trade secret material. See Tr. at 166-67; see also Ag. Exh. 2 at 2. No discussion occurred
    between the Agency and petitioner prior to any of the changes made between the draft
    determination letter and final determination letter.
    Petitioner’s disagreement with some of the specific determinations made by the Agency
    is the subject of this consolidated appeal.
    Petitioner’s Manufacturing Process
    Petitioner operates a manufacturing facility in Danville, Illinois (facility) for two
    different types of food packaging: (1) cellulose food casings and (2) plastic packaging for

    7
    meat products. Tr. at 6. The operations are linked at the site through common utilities and
    services but their unit operations are quite different. Ag. Rec., App. No. 95120325 at 0009;
    Ag. Rec., App. No. 95120326 at 0011.
    Cellulose Food Casing
    Petitioner primarily manufactures regenerated cellulose sausage casings at its facility.
    Tr. at 22. The three types of sausage casings include: (1) the “hot dog” type of casing which
    has a trade name, the “Wienie Pak”; (2) the deli-pack casings, which are slightly larger and
    used for stuffing hams; and (3) the fibrous product which is a large type of casing that comes
    with a paper reinforcement. Tr. at 22; see Pet. Exh. 1.
    The cellulose food casing process includes a chemical department, wienie pak (W/P)
    operations, and fibrous operations. The following process machines within the W/P process
    department have been interpreted to be emission units: 1, 2, 3, 4, 5, 6, 7A, and 7B. In the
    fibrous process areas, the following process machines are emission units: 8, 9, 10, and 10 ½.
    Also included as emission units within the cellulose food casing process area are the barrates,
    viscose makeup, lagoon inlet, and lagoon outlet.
    The cellulose food casing manufacturing operations operate under two relevant permits.
    Permit number 73110109 (I.D. No. 183804AAL) regulates emissions for the extrusion lines
    and the chemical department. This permit contains emission limits for all of the combined
    process units and process unit 7A individually. See Pet. Exh. 4; Tr. at 37-38. The cellulose
    food casing manufacturing operations also operate under construction permit number 97090100
    which pertains to process units 8, 9, and 10 individually. This permit contains further
    emissions limitations in addition to the limitations found in the operating permit. See Pet.
    Exh. 5; Tr. at 39. Process units 7A, 8, 9, and 10 are the only units in the cellulose food
    casing operation that are subject to separate permitted emissions limitations. Tr. at 40. The
    permits for the cellulose operations limit the emission units which emit carbon disulfide (CS
    2
    )
    and hydrogen sulfide (H
    2
    S). Tr. at 38. For an individual cellulose processing unit, gaseous
    CS
    2
    is evolved in the process machines and is ventilated through the process ventilation
    equipment and emitted through a stack. Tr. at 87.
    Plastic Packaging
    The plastic packaging manufacturing operations area contains printing presses which
    use film, ink, adhesive, and solvents to print, laminate or print/laminate combined. Tr. at
    122-23; see Pet. Exh. 2. Additionally, plate making and equipment cleanup are also
    conducted in the plastics operation. In the plastics operation, the following presses are
    considered emission units: 4, 5, 6, 7, the W/P Flexopress 1, and W/P Flexopress 2, and the
    washroom area.
    The plastics packaging manufacturing area operates under permit number 74100015
    (I.D. No. 183804ABF). See Pet. Exh. 6. This permit limits the volatile organic material
    (VOM) emissions for press 7 individually, and for presses 4, 5, 6, and the washroom area.

    8
    This permit also limits the VOM emissions for two W/P presses on a combined basis. Tr. 40-
    41, 107-108.
    Information at Issue
    The issue before the Board is whether certain information which petitioner provided to
    the Agency in its two CAAPP applications warrants trade secret protection under the Act and
    relevant regulations. Specifically, petitioner believes that the following categories of
    information warrants trade secret status: (1) the typical and maximum raw material usage
    rates; and (2) the typical and maximum emission rates. The categories of information on the
    CAAPP forms which petitioner claimed as trade secret are listed in the table below.

    ARGUMENTS AND ANALYSIS
    4
    The Board notes that petitioner did not raise, anywhere in the record, any appeal of the
    Agency’s determination regarding pages 756-759 (Ag. Rec., App. No. 95120325 at 009-0012)
    of the plastics packaging CAAPP application and for pages 125-140 (Ag. Rec., App. No.
    95120326 at 0011-0026) of the cellulose food casing CAAPP application. Also, petitioner did
    not present the Board with rationale as to why Exhibit 6 of the plastics packaging application
    should be protected as trade secret (see pages 1030-1033, Ag. Rec., App. No. 95120325 at
    0153-0156). Therefore, the Board will not review the items discussed within those sections.

    9
    First the Board will make a threshold determination as to whether the claimed trade
    secret information constitutes emission data. The Board then addresses whether any of the
    information constitutes a trade secret.
    Determination of Emission Data
    In this section the Board reviews the arguments of the parties, with regard to the
    determination of emission data, in three sections: (1) typical and maximum raw material usage
    information (line 21(a) of CAAPP Form 220); (2) typical and maximum emission rates (line
    37 of CAAPP Form 220); and (3) line 38 of CAAPP Form 220; table 6 of CAAPP Form 215;
    and line 16 of CAAPP Form 204. After a summary of each party’s arguments, the Board then
    discusses its findings on each of those sections.
    5
    Typical & Maximum Raw Material Usage Information
    (Line 21(a) of CAAPP Form 220)
    Petitioner’s Arguments. Petitioner asserts that the typical and maximum raw material
    usage information is not classified as emission data and therefore should not be disclosed to the
    public. Petitioner believes that because the individual units do not have specific permitted
    emission restrictions, the disclosure of maximum and typical information for individual
    process units could lead competitors to information related to production capabilities. Pet. Br.
    at 10. If the typical and maximum emissions vary greatly, petitioner asserts that the
    competitor could learn that additional capacity exists which may not be permitted but which
    could potentially be used by the facility. Pet. Br. at 10; see Tr. at 59-61.
    Petitioner also argues that the term “emission data” is defined narrowly so as not to
    require disclosure of information which is only of value to a submitter’s competitors. Pet. Br.
    at 8. Petitioner believes that typical and maximum raw material usage information and typical
    and maximum emissions information are not emission data as defined by the USEPA definition
    found at 40 C.F.R. Section 2.301(a)(2)(i) since the definition does not include any reference
    to typical and maximum raw material usage. Additionally, petitioner argues that raw material
    usage information is excluded in the Agency’s definition found at 2 Ill. Adm. Code
    1827.Appendix A(2)(c). Pet. Br. at 12-13. Petitioner further points out that pursuant to 2 Ill.
    Adm. Code 1827.Appendix A(2)(c), if the Agency is able to provide, by some other means,
    information on the amount of a pollutant that is actually emitted, then information on the
    “type, amount and method” of use of raw materials used in the process of the submitter may
    be claimed as a trade secret. Pet. Br. at 15.
    Petitioner acknowledges that information necessary to determine actual emissions can
    be considered as emission data; however, petitioner argues that the raw material information it
    submitted in its applications cannot be used to determine actual emissions since the information
    is based on theoretical typical and maximum raw material use rather than actual raw material

    use. Petitioner argues that it submitted theoretical numbers to show that the maximum raw
    material rates for an individual machine was the maximum amount of raw material that could
    be used on that line. Pet. Br. at 16.
      
      
    Even if the Board determines that the information at issue constitutes emission data,
    petitioner requests that the Board only require that the necessary information be disclosed to
    the public. Petitioner states that because the typical and maximum raw material use
    information given was for individual process machines, petitioner submitted more information
    than was necessary to determine emissions from the facility. Pet. Br. at 14, 18. Petitioner
    asserts that it provided raw material use information on line 21(a) of CAAPP Form 220
    separately for each of its individual process units. Petitioner further argues that if individual
    units are not subject to specific per line emissions limitations, then individual typical and
    maximum raw material usage information is irrelevant to determine compliance with the group
    emission limits. Pet. Br. at 18. In this regard, petitioner notes that not all of its individual
    process units are subject to individual emission limits. Pet. Br. at 18-19.
    Petitioner asserts that it had no objection to providing actual raw material use
    information for all the cellulose manufacturing equipment combined or all the plastic
    packaging equipment combined, but that option was not presented by the Agency. Pet. Br. at
    19-20. Petitioner argues the same with regard to the plastics packaging 220-CAAPP forms.
    Pet. Br. at 19-20. Petitioner distinguishes its case from Classic Finishing and Duo Fast by
    stating that those matters concerned emissions rate information for individual process machines
    while petitioner’s units are, for the most part, not subject to individual line limits. Reply Br.
    at 10-12. Petitioner therefore asserts that actual emissions from individually regulated units
    should not be protected by trade secret as exemplified by the Classic Finishing and Duo Fast
    cases, but units that are not individually regulated should be subject to trade secret protection.
    Agency’s Arguments. The Agency believes that the raw material usage and emission
    rate information sought by each of the CAAPP forms constitute emission data and, thus,
    cannot be protected as trade secret. Ag. Br. at 8. The Agency states that it performed the
    trade secret review of petitioner’s CAAPP permit applications in order to comply with the
    public notice requirements of the Illinois CAAPP (see 415 ILCS 5/39.5 (1996)). Ag. Br. at 6-
    7. Additionally, the Agency states that its CAAPP permit application forms adhere to the
    content requirements set forth in the CAAPP procedures set forth in Subpart D of 35 Ill. Adm.
    Code 270, adopted by the Agency pursuant to 415 ILCS 5/39.5(y) (1996). The Agency states
    that its trade secret determination in this proceeding is premised on the view that raw material
    usage rates from line 21(a) of CAAPP Form 220, the identity and emission rates of HAPs in
    CAAPP Form 215, emission rates from line 37 and 38 of CAAPP Form 220 and line 16 of
    CAAPP Form 204 are, by nature, emission data. Ag. Br. at 12.
    The Agency maintains that consideration of information sought by those specific lines
    in the CAAPP forms as emission data is supported by the USEPA’s definition (40 C.F.R.
    Section 2.301(a)(2)(i)). The Agency argues that its concept of emission data is broader than
    the petitioner’s interpretation that it is limited to specific data on the nature and amount of
    emissions. The Agency maintains that emission data does not only include data regarding
    actual emissions, but also the information necessary to determine that emission data. Ag. Br.

    11
    at 27. Information that bears upon the identity, amount, frequency, concentration or other
    characteristics is also necessary, the Agency believes.
    The Agency refers the Board to the accompanying instructions of CAAPP Form 220
    (Ag. Exh. 1, paragraph 21(a)) which state that the raw material information for the emission
    unit must be provided to the extent such information is emission related, needed to determine
    or regulate emissions, or needed to determine rule applicability or compliance. Ag. Br. at 13.
    The Agency notes that the raw material information requested in line 21(a) helps in identifying
    how the process unit is governed by the existing regulations, the type of pollutants that may be
    emitted from the process, and to what process the emissions rates may be attributable. Ag. Br.
    at 14. The Agency argues that the information in line 21(a) of CAAPP Form 220 reveals
    “characteristics” of emissions caused or allowed by the permit applicant that are inherently
    emission related. Ag. Br. at 17-18.
    The Agency believes that the importance of raw material information as a means to
    calculate emissions should not be diminished merely because it may be used on a theoretical
    basis. Ag. Br. at 15. Further, the Agency asserts that even if the typical and maximum usage
    rates do not reflect a direct correlation with petitioner’s past actual usage rates and emissions,
    the information provided by petitioner is still related to a determination of emissions under the
    assumed set of circumstances. Ag. Br. at 18. In this regard, the Agency explains that the
    term “typical” is meant to relate to actual operation of an emission unit as it occurred in the
    past, as it is presently occurring, and as it is expected to occur in the future. Ag. Br. at 19.
    With regard to “maximum,” the Agency notes that it is supposed to represent a set of
    circumstances that has rarely, if ever, occurred, or may never occur in the future.
    Id.
    In
    effect, the Agency asserts that both typical and maximum data should be characterized as
    actual emission data.
    In response to petitioner’s argument that the language in 2 Ill. Adm. Code
    1827.Appendix A requires the Agency to provide, by some other means, information on the
    amount of a pollutant, the Agency asserts that Appendix A should not be given “lawful or
    binding effect.” The Agency relies on Duo Fast, and states that the Board “arguably
    overturns” the language of Appendix A in the Duo Fast decision. Ag. Br. at 32-33.
    Alternatively, the Agency states that if the Board chooses to give meaning to Appendix A,
    petitioner has not adequately demonstrated that other emission data is available for disclosure
    to the public. Ag. Br. at 33.
    The Agency cannot comprehend how petitioner’s “inflated” raw material usage as
    reported on line 21(a) of CAAPP 220 Form could be deemed to have any competitive value
    since the information does not represent actual numbers. Additionally, the Agency hints that it
    may, in the future, require petitioner to supplement its CAAPP permit applications with more
    representative data. Ag. Br. at 19.
    Finally, with regard to petitioner’s contention that the raw material usage information
    provided in the CAAPP forms is more information than necessary to show compliance, the
    Agency states that the petitioner does not address the obligation to publicly disclose data with

    12
    respect to actual emissions. Ag. Br. at 20. The Agency cites Classic Finishing to support its
    position that information should be provided for emission units that are not subject to unit-
    specific limitations. The Agency notes that even assuming that data is not required for certain
    emission units that are not individually regulated, unit-by-unit data would be required to
    determine the emissions from the group of regulated units. Ag. Br. at 20; see Tr. at 241-46.
    Discussion. In order to determine whether the typical and maximum raw material
    usage information provided by petitioner is emission data, the Board must first determine
    whether raw material information meets the informational requirement specified in the
    USEPA’s definition of emission data under Section 2.301(a)(2)(i), 40 C.F.R. 2.301. While
    the definition does not specifically describe typical and maximum raw material usage rates as
    emission data, the definition includes information necessary to calculate emission data. This is
    pertinent for the matter at hand since the information offered for line 21(a) contains certain
    information necessary to calculate emission data.
    In Classic Finishing, the Board found that the federal definition of “emission data” is
    focused not only on the emissions figure, but also on the “information
    necessary to
    determine . . .
    emissions.” See Classic Finishing, PCB 84-174, slip op. at 2 (emphasis
    added). The Board noted that emission data in many instances, as in Classic Finishing, is a
    calculated, rather than monitored number. Classic Finishing, PCB 84-174, slip op. at 2. In
    Duo Fast, the Board construed the phrase “necessary to determine” in the federal definition to
    broaden, rather than limit, what constitutes emission data. See also Duo Fast, PCB 87-4, slip
    op. at 4. Further, the Board stated that the broad scope is necessary because in most
    circumstances involving air pollution sources, there is no way to instantaneously measure and
    record actual air emissions. The Board noted that the broad interpretation of the definition
    also ensures that emission data can be verified, rather than being presented as a single number
    without supporting data or calculations. Duo Fast, PCB 87-4, slip op. at 4. In this regard, the
    Board noted that air emissions are typically calculated from a variety of data, including raw
    material usage information.
    In the USEPA’s policy statement (see 56 Fed. Reg. 7042), the USEPA lists specific
    data which the USEPA considers to constitute emission data. Raw material usage information
    is not included on the USEPA’s list. However the Board notes that USEPA states, “[t]his list
    is not exhaustive and, therefore, other data might be found, in a proper case, to constitute
    emission data.” See Ag. Rec., App. No. 95120325 at 0168-0171; App. No. 95120326 at
    0298-0301. The Agency testified at hearing that raw material information is routinely used to
    calculate emission rates. Tr. at 199. The raw material usage information helps in identifying
    how a process unit is governed by existing regulations, the type of pollutants, the type of
    pollutants emitted, and to what process the emission rates may be attributable. Although raw
    material usage information is not listed specifically on the USEPA’s list, the Board believes
    certain raw material usage information is needed to calculate emission rates. Since these raw
    material usage rates are emission related, the Board finds that certain raw material usage
    information constitutes emission data.

    13
    Petitioner also argues that pursuant to 2 Ill. Adm. Code 1827.Appendix A, the Agency
    can provide information on the amount of a pollutant by some other means from information
    submitted in the CAAPP. Appendix A of Part 1827 refers to the federal definition for the
    meaning of emission data and adds that reports and printouts from the Agency’s Total Air
    System, stack test reports, quarterly and annual emission reports, malfunction reports,
    compliance status reports, and Agency field reports are emission data. Further, Appendix A
    states that “if the Agency is able to provide, by some other means, the identity, amount,
    frequency, concentration, or other characteristics, to the extent related to air quality,” then
    certain information may be claimed to be trade secret. The Board does not agree with
    petitioner that the Agency can provide information on the amount of a pollutant by some other
    means from information already submitted since there is no other information in this record to
    be able to determine the emission rates.
    The Board next addresses whether the typical and maximum raw material usage
    information, which petitioner estimated on a theoretical basis, is emission data. Petitioner
    contends that the raw material information submitted on line 21(a) of CAAPP Form 220 does
    not reflect actual usage and, therefore, does not constitute emission data. The raw material
    information required on line 21(a) of CAAPP Form 220 is intended to satisfy the informational
    requirements specified at 35 Ill. Adm. Code 270.403. Specifically, the Agency regulations for
    CAAPP application contents at Section 270.403(h) require that the CAAPP application include
    information for each emission unit and each mode of operation, for which a permit is sought,
    to the extent they are related to air emissions, raw material used, and raw material usage rates.
    Petitioner chose to provide typical and maximum raw material information based on
    theoretical estimation to meet the informational requirement and then used that information to
    calculate the emission rates. While petitioner claims that raw material information provided in
    the CAAPP application was inflated, the information is still necessary for evaluating the
    application. As argued by the Agency, the importance of raw material data as a means to
    calculate emission rates does not diminish merely because the information is based on
    theoretical estimates. The Board believes that the raw material information is related to
    emission rates; therefore, consistent with the discussion immediately following, the Board
    finds that certain raw material information related to emission rates should be disclosed to the
    public.
    The Board next addresses whether, in light of Classic Finishing and Duo Fast, the term
    “emission data” encompasses the line-by-line data provided by petitioner in its permit
    application or whether, as argued by petitioner, raw material can be considered in the
    aggregate in accordance with Section 7(c) of the Act and Board case law. In other words, the
    immediate issue at hand is whether the raw material data for emission units which are
    regulated individually and emission units which are regulated on a combined/aggregate basis
    require public disclosure. In Classic Finishing, the Board held that the point at which a source
    is regulated must be examined in determining whether the Act requires disclosure of emission
    data on a plant-wide basis or an individual equipment basis. Classic Finishing, PCB 84-174,
    slip op. at 3. See also Duo Fast, PCB 87-4, slip op. at 5-6. Given the fact that the units in
    Classic Finishing were subject to individual limits, the Board held that information must be

    14
    provided for individual machines, as well as for the whole plant, since the data on emissions
    by each machine may very well be significant to members of the public. Classic Finishing,
    PCB 84-174, slip op. at 3.
    Regarding the equipment which is regulated on an individual basis, the Board, in this
    matter, follows Classic Finishing and Duo Fast. The Board therefore finds that emissions
    information of equipment which is individually regulated should be disclosed to the public (as
    in Duo Fast and Classic Finishing) as emission data. In making this finding, the Board affirms
    the Agency’s decision requiring that the emission levels from process units 7A, 8, 9, and 10 of
    the cellulose food casing process, and press 7 of the plastic packaging process be disclosed to
    the public.
    Regarding the emission units which are regulated on a combined or aggregate basis, the
    Board again relies upon the reasoning in Classic Finishing and Duo Fast. In those matters, the
    Board looked to the point at which the units were regulated to determine if certain information
    must be disclosed to the public pursuant to Section 7 of the Act. Again, here, the Board
    believes that the information which constitutes disclosable emission information, as required
    under Section 7(c) of the Act, is the information listed for the point at which a source is
    regulated. Since the Agency utilizes the combined or aggregate emission data to determine the
    CAAPP permit emission levels for two or more emission units that are regulated on a
    combined basis, the Board finds that for such process units, emission data should be disclosed
    to the public only as a combined or aggregate value, rather than an individual value.
    In making the findings above, the Board reverses the Agency’s decision requiring that
    each individual line information, rather than the combined or aggregate information, be
    disclosed to the public. The Board therefore finds that the raw material usage rates from
    process units 1, 2, 3, 4, 5, 6, 7B, 10 ½, the barrates, viscose makeup, lagoon inlet, and
    lagoon outlet of the cellulose food casing process, and presses 4, 5, 6, W/P presses 1 and 2,
    and the washroom area of the plastics packaging process area need not be disclosed on an
    individual basis, but on an aggregate or combined value for the disclosure of emission data.
    Typical & Maximum Emission Rates (Line 37 of CAAPP Form 220)
    Petitioner’s Arguments. Petitioner states that the Agency incorrectly determined that
    typical and maximum emission rates on line 37 of CAAPP Form 220 is emission data for the
    same reasons as the determination of raw material use information is emission data. Petitioner
    argues that the typical and maximum emission rates are not specifically defined as emission
    data pursuant to either the USEPA definition (40 C.F.R. Section 2.301(a)(2)(i)) or the
    Agency’s definition (2 Ill. Adm. Code 1827.Appendix A(2)(c)). Pet. Br. at 20-21.
    Petitioner believes that its reported typical and maximum emissions information from
    the individual units are not actual emissions information because they are based on theoretical
    and not actual emissions. Pet. Br. at 21-22. Petitioner asserts that typical and maximum
    emission information on line 37 was based on the direct relationship of line 37 to the
    information listed on line 21(a); therefore, petitioner believes that such information is not the

    15
    same as actual emissions. Pet. Br. at 21. Petitioner notes that the typical and maximum
    emission data on line 37 of CAAPP-Form 220 is higher than what it actually emits or is
    permitted to emit.
    Id.
    Petitioner states that it used the higher rates because petitioner hoped to
    avoid individual unit emission limits which would limit production in the future under the new
    Title V program. Pet. Br. at 21; see Tr. at 116-17. Also with regard to the plastics packaging
    operations, line 37 information was also obtained by examining the raw material usage from
    line 21(a). Pet. Br. at 22-23.
    Regarding the emission information for individual process units, petitioner again argues
    that emission information for individual lines is more information than is necessary to
    determine whether the facility is in compliance with the applicable emissions limitations or to
    determine the effects on air quality. Pet. Br. at 23. Petitioner asserts that if individual units
    are not subject to specific per line emissions limitations, the individual typical and maximum
    emission information is not necessary to determine compliance with the group emission limits.
    Id
    . Petitioner explains that the Board, in two cases, found that emission data from individual
    units was relevant to determine compliance and should be disclosed to the public. See Classic
    Finishing and Duo Fast. But petitioner believes that the reasoning in these two cases should
    not apply to the instant matter since petitioner’s individual processing units are, for the most
    part, not subject to an individual emissions limits like the units in Classic Finishing and Duo
    Fast.
    Agency’s Arguments. The Agency states that line 37 of CAAPP Form 220 requests a
    variety of information, including typical and maximum rates of actual emissions for the
    specified pollutants. Ag. Br. at 21. The Agency notes that the accompanying instructions to
    line 37 (see Ag. Exh. 1) state that the maximum emissions are to be based on emissions that
    theoretically could be emitted by the unit if it were operated at the maximum design capacity
    or maximum production capacity. Ag. Br. at 22. The Agency asserts that the maximum
    emission rates are significant for assessing compliance because of inherent inefficiencies of
    control equipment at higher rates.
    Id.
    The typical emission rates are also needed to analyze
    what is usually going to be occurring with respect to emission rates for a source or emission
    unit. Ag. Br. at 23.
    The Agency notes that maximum and typical emission rates would be used for the dual
    purpose of determining emissions and determining rule applicability. The Agency contends
    that the USEPA “emission data” policy supports its position (see Ag. Rec., App. No.
    95120325 at 0168-0171; Ag. Rec., App. No. 95120326 at 0298-0301; 56 Fed. Reg. 7042).
    In this regard, the Agency notes that emission rates are specifically identified in the policy as a
    specific data field which constitutes emission data. Ag. Br. at 23-24. The Agency argues that
    even if the USEPA’s policy statement is interpreted narrowly to apply only to actual emission
    rates, the information is “characteristic” of emission that can, or will, be emitted and is
    instructive as to whether emissions may be authorized under an applicable standard.
    Discussion. The emission rate information provided in petitioner’s CAAPP
    applications pertaining to regulated air pollutants, HAPs, and malfunctions are intended to
    satisfy the informational requirements specified in the regulations underlying the CAAPP

    16
    application forms. Since petitioner has addressed the issues pertaining only to emission rates
    of regulated air pollutants on line 37 of CAAPP Form 220, the discussion is limited to line 37.
    The Agency regulations relating to CAAPP application contents at 35 Ill. Adm. Code
    270.403(e) require the CAAPP application to include the maximum and typical emission rates
    for each emission unit and each mode of operation for which a permit is being sought. The
    regulations require such information to establish the applicability of requirements and
    compliance with the applicable limitations and standards. The emission rate information
    provided by the petitioner is intended to satisfy Section 270.403(e). Even though the emission
    rates information is based on theoretical raw material usage, the Agency must use this
    information to determine applicable requirements and establish permit limits. Therefore,
    consistent with the discussion above under the raw material usage rates, the Board finds that
    the emission rate information for the units which are individually regulated and the
    combined/aggregate emission information for those units which are regulated on a
    combined/aggregate basis is emission data and disclosable to the public under Section 7(c).
    Line 38 of CAAPP Form 220; Table 6 of CAAPP Form 215;
    Line 16 of CAAPP Form 204
    Petitioner’s Arguments. Petitioner has not addressed in detail the issue of why
    emission data associated with HAPs (CAAPP Forms 215, 220) and malfunction/breakdown
    (CAAPP Form 204) must be protected as trade secret. However, petitioner states that such
    information must be protected for the same reason the information on line 37 of Form 220 is
    trade secret. Pet. Br. at 3, n.3.
    Agency’s Arguments. The Agency maintains that emission rates of HAPs on line 38 of
    CAAPP Form 220 is, by its very nature, emission data. The Agency notes that the rationale
    for its conclusion is essentially the same as that for the emission rates on line 37 of CAAPP
    Form 220. Ag. Br. at 24. Regarding the HAPs summary information in table 6 of CAAPP
    Form 215, the Agency states that the purpose of the information is to provide an overall
    perspective about the identity and amounts of HAPs to be emitted by a source. Ag. Br. at 25.
    The Agency relies on its rationale for determining emission rates on line 37 as emission data to
    support its conclusion that information in table 6 of Form 215 is emission data.
    Id.
    Regarding
    line 16 of CAAPP Form 204, the Agency states that information about the maximum and
    typical emission rates experienced during malfunction or breakdown of a process emission unit
    is emission data based on the Agency’s rationale for determining that the emission rates on line
    37 of CAAPP Form 220 are emission data.
    Discussion. For reasons stated earlier, the Board finds that the data associated with
    HAPs (CAAPP Forms 215, 220) and malfunction/breakdown (CAAPP Form 204) constitutes
    emission data only as it relates to individually-regulated units and units which are regulated on
    a combined/aggregate basis.
    Agency’s Procedures on Trade Secret Determination
    Petitioner’s Arguments

    17
    Petitioner’s final argument concerns the Agency’s alleged failure to follow the
    applicable procedures when it denied the trade secret claims. Petitioner believes that the
    Agency failed to provide petitioner any opportunity to dispute the Agency’s belief that the
    information on maximum and typical raw material use was emission data. Pet. Br. at 26.
    Petitioner points out that the Agency flipped its position on line 21(a) of CAAPP Form 220
    where the Agency first found in the January 16 and 21, 1998 draft determination letters that
    line 21(a) was trade secret information, and then found in the January 30, 1998 final
    determination letter that such information was indeed emission data. Petitioner argues that, as
    a result, it did not have a chance to respond to this determination in its letter of January 30,
    1998. Pet. Br. at 26.
    Petitioner asserts that the Agency failed to follow the procedures for a trade secret
    determination in accordance with the trade secret regulations since the Agency did not require
    the January 16 and 21, 1998 requests for justification to be in writing, sent by certified mail-
    return receipt requested, and signed by an authorized representative. See 35 Ill. Adm. Code
    120.215; Pet. Br. at 27. Also, petitioner claims that it may have been able to resolve this
    dispute with the Agency if it had an opportunity to discuss these matters after the Agency
    issued its final determinations on April 24, 1998.
    Agency’s Arguments
    The Agency argues that it did not fail to adhere to the applicable regulations for trade
    secret determination, although the Agency admits that it wrongly identified the January 30,
    1998 letter sent by petitioner to the Agency as a “trade secret claim and justification letter.”
    Ag. Br. at 30-31. The Agency states it did not follow the proper mailing requirements since it
    did not believe that a request for justification from the petitioner was necessary. Ag. Br. at
    31. The Agency states that a request for justification of claims is entirely discretionary on the
    Agency’s behalf under the Part 1827 requirements. Ag. Br. at 31.
    Discussion
    Petitioner argues that the Agency failed to follow the proper applicable procedures in
    making this trade secret determination. In support of its argument, petitioner cites to the
    January 16 and 21, 1998 draft determination letters sent by the Agency via facsimile to
    petitioner and states that such letters did not follow the appropriate procedures pursuant to
    Section 120.215 of the Board’s procedural rules. Additionally, petitioner relies on the fact that
    the final determination letter of April 24, 1998, included substantive changes from the original
    draft determination letters to which petitioner did not have a chance to respond. Petitioner
    claims that had the Agency given petitioner a chance to discuss these matters, some resolution
    may have resulted between the parties. The Agency vehemently denies that it did not follow
    the proper procedures and it states that an Agency request for justification of claims is
    discretionary.
    The procedures in place for a trade secret claim emanate from Part 120 of the Board’s
    procedural rules (35 Ill. Adm. Code 120). The Agency may adopt additional procedures that

    18
    are not inconsistent with Part 120, as allowed by Section 120.401 of the Board’s rules. As a
    result, the Agency adopted 2 Ill. Adm. Code 1827.
    One question before the Board is whether the Agency’s January 16 and 21, 1998 draft
    determination letters were requests for justification of claims and, as such, whether the Agency
    followed the proper procedures under Section 102.215 and 2 Ill. Adm. Code 1827.203. The
    Agency mistakenly referenced these letters as a “trade secret claim and justification letter,” but
    later refuted this reference. The Board has reviewed these letters (Ag. Rec., App. No.
    95120325 at 0157-0161; Ag. Rec., App. No. 95120326 at 0284-0291). Nowhere on these
    draft determination letters does it appear to state that such drafts are an Agency request for
    justification of claims. The draft letters do not reference any of the requirements necessary for
    requests for justification of claims found in Section 102.215 and 2 Ill. Adm. Code 1827.203.
    The Board finds that the Agency did not intend the letters of January 16 and 21, 1998, to be
    requests for justification of claims pursuant to the Board’s rules and the Agency’s rules. The
    Board also notes that the Agency may request a justification under the rules, but is not required
    to do so.
    Another question before the Board is whether the Agency allowed time to give
    petitioner a chance to respond to its final determination letter of April 24, 1998. Under the
    rules, the Agency is not required to do so.
    Finally, the Board addresses the timeliness of the Agency’s decision on the trade secret
    requests in petitioner’s CAAPP applications. Under the rules, the Agency is required to make
    its determination within ten working days. See 2 Ill. Adm. Code 1827.204; 35 Ill. Adm.
    Code 120.225. The time may be extended for a second period of ten working days if the
    Agency demonstrates that an extension is necessary and notifies the submitter of the extension.
    Id.
    Here, the Agency received the CAAPP applications in late 1995 and did not notify
    petitioner until January 1998. The record does not include any communications, if any, which
    the Agency had with petitioner to discuss any extension of time to allow the Agency to make
    its determination. The record is also silent in explaining why the Agency took such a long
    period of time to arrive at a determination on these trade secret requests. The Agency should
    follow the Board’s rules, as well as its own procedural rules, in making its determinations for
    a trade secret request. In the least, the Agency should be in contact with the petitioner to
    inform the petitioner of the status of its request. Otherwise, pursuant to Section 120.250(c),
    the petitioner can proceed to file its trade secret determination with the Board if the Agency
    fails to make a final determination within the time limits prescribed in Part 120. See Pillsbury
    v. IEPA (November 19, 1998), PCB 99-60.
    Trade Secret Determination
    Having determined that the information pertaining to individual units that are regulated
    on a combined/aggregate basis are not subject to Section 7(c) of the Act, the Board will now
    determine whether such information constitutes a trade secret. As defined in the Act, trade
    secret information is “scientific or technical information, design, process (including a
    manufacturing process), procedure, formula or improvement, or business plan which is secret
    in that it has not been published or disseminated or otherwise become a matter of general

    19
    public knowledge, and which has competitive value.” 415 ILCS 5/3.48 (1996). Trade secret
    information is an exception to the generally recognized public openness requirement found in
    Section 7 of the Act, specifically that all “files, records and data” of the Board and the Agency
    must be “open to reasonable public inspection.” 415 ILCS 5/7 (1996).
    Under the Act and Part 120, a trade secret must meet a two-pronged test: (1) it must
    have been kept secret and confidential; and (2) it must have competitive value. See 35 Ill.
    Adm. Code 120
    et seq
    .; see also Classic Finishing, PCB 84-174, slip op. at 4; Duo Fast, PCB
    87-4, slip op. at 8-9.
    Confidentiality
    Petitioner asserts that it has kept the claimed trade secret information confidential.
    Specifically, petitioner states it would not disclose the information claimed as trade secret
    except as necessitated by the CAAPP applications. Petitioner safeguards the information at its
    Danville facility with a 24-hour guard service and computerized plant entry system thereby
    assuring that no unauthorized entry takes place. Additionally, the information is stored in
    locked drawers. Any person who is not employed by petitioner who views the information
    must sign a corporate secrecy agreement. Tr. at 45. Petitioner only allows a very limited
    segment of management and staff to access the application information. Ag. Rec., App. No.
    95120325 at 0003-05; Ag. Rec., App. No. 95120326 at 0003-05.
    On the basis of these statements, the Board finds that the information involved meets
    the first prong of the two-pronged trade secret test.
    Competitive Value
    Petitioner also claims that the trade secret information has competitive value.
    Petitioner filed its request for trade secret when filing its CAAPP applications since it believes
    the information is valuable to its competitors only. Tr. at 10. In particular, petitioner states
    that the detailed operating data, required in the emissions determinations, could be of
    significant competitive value. Petitioner tries to keep all kinds of information from its
    competitors such as basic production data, production capacity information, cost of
    manufacturing information, sales information, product improvements, and processing
    improvements. Tr. at 44.
    Petitioner claims the raw material data as trade secret material because the competitor
    could use that information to develop further information about its production capabilities and
    actual production at the facility. Tr. at 59. With regard to typical and maximum emissions on
    line 37, petitioner claimed trade secret because it did not want to provide information showing
    the typical and maximum emissions which the emission units equipment could produce. Tr. at
    60-61. These emissions, petitioner claims, are directly related to its production levels. Tr. at
    61. Further, petitioner believes that providing grouped information from the emissions point
    would provide competitive value to a competitor, but in that situation petitioner “understands”
    the requirement to do so. Tr. at 71.

    20
    On the basis of these statements concerning the competitive value of the claimed trade
    secret material, the Board concludes that the second prong of the trade secret test has been
    met. Therefore, the Board finds that the individual information used to compile the
    combined/aggregate values within the CAAPP applications constitutes a protectable trade
    secret. The Board notes that only the combined/aggregate information may be disclosed.
    CONCLUSION
    In summary, the Board finds that the individual line information submitted by petitioner
    should be disclosed to the public because it is emission data. However, for those emission
    units that are regulated on a combined or aggregate basis, the information need not be
    disclosed to the public on an individual basis, but rather on an aggregate or combined basis.
    Accordingly, the Board affirms in part and reverses in part the Agency’s decision of April 24,
    1998. The parties are directed to follow the order below consistent with this opinion.

    Regarding Table 6 of CAAPP Form 215, the Board orders that the hazardous
    air pollutant data for those individual units which are regulated on a
    combined/aggregate basis should be protected as a trade secret. Further, the
    Board orders that the hazardous air pollutant data for such units should be
    disclosed only on a combined/aggregate basis.
    4.
    The remaining claimed trade secret information constitutes air emission data and
    is required to be made available to the public pursuant to Section 7(c) of the
    Environmental Protection Act.
    5.
    The Board orders the Clerk of the Board to continue to protect the determined
    trade secret information pursuant to Subpart C of 35 Ill. Adm. Code 120, and to
    mark these items in red ink with the word “DETERMINED” pursuant to 35 Ill.
    Adm. Code 120.310.
    6.
    The Board orders the Clerk of the Board to continue to protect these articles as
    trade secrets pursuant to Subpart C of 35 Ill. Adm. Code 120 for 35 days from
    the date of this order. If within 35 days the Board does not receive a motion to
    reconsider or modify this order or a notification of a petition for review of this
    order by a court of competent jurisdiction, the Clerk is ordered to make these
    articles available for public inspection and to notify the owner.
    7.
    If the Board receives a motion to reconsider or modification of this order or a
    notification of a petition for review of this order by a court of competent
    jurisdiction, the Clerk is ordered to continue to protect these articles as trade
    secrets pursuant to Subpart C of 35 Ill. Adm. Code 120, until otherwise ordered
    by the Board.
    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 3rd day of 1998 by a vote of 6-0.
