    OPINION AND ORDER OF THE BOARD (by J. Yi):
    Pursuant to Sections 9.5, 27 and 28 of the Environmental Protection Act (Act) (415
    ILCS 5/9.5, 27 and 28), the Illinois Environmental Protection Agency (Agency) filed this
    rulemaking proposal on October 13, 1995. In addition to the proposal the Agency filed a
    motion to waive certain filing requirements, to expedite the hearing process and to consolidate
    R90-1(C), In the Matter of: Toxic Air Contaminant List (35 Ill. Adm. Code 232); Reporting
    Requirements for Emission Sources and R90-1(D), In the Matter of: Toxic Air Contaminant
    List, Styrene (35 Ill. Adm. Code 232.Appendix A), into this proceeding.
    In our order of November 2, 1995 we granted the Agency's motions and found that the
    filing met the requirements of Sections 27 and 28 of the Act. The Board also accepted this
    matter for hearing and directed the hearing officer to set this matter for hearing. Additionally,
    the Board, in separate orders closed the dockets in both R90-1(C) and (D).
    The Board held two hearings in this matter. The first hearing was held on February
    23, 1996 in Springfield, Illinois. The second hearing was held on April 9, 1996 in Chicago,
    Illinois. The post-hearing comment period ended May 17, 1996.
    On August 1, 1996, the Board sent this rulemaking proposal for First Notice. Pursuant
    to Section 5.01 of the Illinois Administrative Procedure Act (IAPA) and Section 102.342 of
    the Board's procedural rules, the 45-day public comment period commenced upon publication
    of the August 1 opinion and order in the Illinois Register, during which the Board accepted
    written comments.
    On January 9, 1997 the Board adopted an interim opinion and order proposing a
    Second Notice for further comments. The Board allowed public comments on the proposed
    Second Notice to be filed until February 14, 1997. On March 20, 1997 the Board adopted a

    2
    Second Notice in this matter. The rule was filed with the Joint Committee of Administrative
    Rules (JCAR) and on April 15, 1997 JCAR voted a certification of no objection to the rule.
    Today the Board proceeds to Final Notice with this rule. During the Second Notice
    period, the Board made several non-substantive changes and one substantive change at the
    request of JCAR.
    PURPOSE OF THE PROPOSAL
    The Agency's proposal has two main purposes, both of which are connected to the
    Illinois' Toxic Air Contaminant (ITAC) list. First, the proposal updates the ITAC list by
    adding chemicals or substances to 35 Ill. Adm. Code Appendix A that have been either listed
    as federal Hazardous Air Pollutants (HAPs) under Section 112(b) of the Clean Air Act (CAA)
    as amended in 1990, or targeted as chemicals or compounds of concern under the United
    States Environmental Protection Agency's (USEPA) "Great Waters" program under Section
    112(m) of the CAA. In addition to updating the ITAC list, the proposal requires all sources
    which meet the applicability criteria to submit an ITAC Source Report (emissions report) for
    the calendar year 1996. Finally, the proposal corrects typographical errors which appear in
    the current ITAC list.
    SUMMARY OF PROPOSED AMENDMENTS
    This portion of the opinion will discuss the proposed amendments to 35 Ill. Adm. Code
    232 section by section.
    Section 232.120 Definitions
    The proposed amendments to Section 232.120 delete definitions no longer applicable to
    this Part as a result of revisions to 35 Ill. Adm. Code 211 and add definitions for “commercial
    fuel”, “Illinois Toxic Air Contaminant”, “ITAC Source Report”, “manufacture”, “otherwise
    use”, “process”, and “Toxic Air Contaminant” (TAC). The definition of “commercial fuel”
    is necessary because Section 9.5(e)(3) of the Act exempts emissions of ITACs from
    combustion processes using commercial fuel from the source reporting requirements. The
    definitions of “manufacture”, “otherwise use” and “process” are added to address applicability
    thresholds. These definitions are identical in substance to those in Section 313 of the
    Emergency Planning and Community Right to Know Act, Title III of Superfund Amendments
    and Reauthorization Act of 1986 (SARA Section 313) (42 U.S.C. 11001
    et seq
    .) The
    definitions of ITAC and TAC are added to delineate only those chemicals listed in Appendix A
    that are subject to this proposal. “ITAC Source Report” is added as a definition to address
    what information is required to be reported under this proposal.
    Section 232.120 is revised to delete the definitions of “New emission source” and
    “Process unit” since these definitions were inconsistent with, or are no longer necessary
    because of, earlier revisions to Part 211 that resulted from another rulemaking.

    3
    The Agency’s proposal to the Board suggests that the definition of “‘Emits’ or
    ‘Emissions’ or ‘Emitted’”, be deleted because of earlier revisions to Part 211. However the
    definition of “‘Emits’ or ‘Emissions’ or ‘Emitted’”, contains the definition of “Fugitive
    emission” which is not defined in either Part 201 or 211. The definition of “Fugitive
    emission” appears only at Section 203.124. Since Parts 201 and 211 do not contain a
    definition of “Fugitive emission”, the definition of “‘Emits’ or ‘Emissions’ or ‘Emitted’” is
    deleted, but the definition for “Fugitive emission” is retained.
    Subpart D: Source Identification Requirements
    Sections 232.400 through 232.460 contain the requirements relating to source
    reporting. Section 232.400 states the purpose of Subpart D.
    Section 232.410(a) provides the applicability threshold which is any source that
    manufactures, processes, or imports 25,000 lbs. or more of any individual ITAC in any
    calendar year, or otherwise uses 10,000 lbs. of any individual ITAC in any calendar year.
    Section 232.410(b) lists those processes or operations that are not subject to Subpart D, and
    incorporates the exemptions in Section 9.5(e) of the Act. Section 232.410(c) provides for an
    additional applicability threshold, beyond the threshold in Section 232.410(a).
    Section 232.420 provides that the Agency will supply to all sources expected to be
    affected by this proposal an ITAC Source Report that contains all the data fields required by
    Subpart D. This report is designed to assist affected sources in complying with the
    requirements of Subpart D, although the information need not be submitted on this form. The
    ITAC Source Report form is similar to the form being utilized in SARA Section 313.
    Section 232.421 requires that all emission reports submitted pursuant to Subpart D be
    certified, and specifies the criteria for a certifying individual, as well as the required
    certification.
    Section 232.423 provides that the failure of an affected source to receive an ITAC
    Source Report from the Agency does not relieve a source from the obligation to file an
    emissions report.
    Section 232.430(a) specifies the date by which a source must file an emissions report
    and lists the information required to be submitted. Section 232.430(b) lists which emissions of
    ITACs are considered to be
    de minimis
    and therefore not subject to reporting. Section
    232.430(c) specifies the date for reporting for sources that become subject to this proposal
    after January 1, 1996. Section 232.430(d), (e), and (f) list when a source must submit a
    revised emissions report to the Agency.
    Section 232.440 allows a source to use engineering estimates to determine emissions if
    the type of estimate is reasonable, is specified and is the best information available. The
    Section also notes that this Subpart does not require additional monitoring or testing in
    connection with these emissions reports.

    4
    Section 232.450(a) provides that the Agency may request additional information
    beyond that initially submitted or specified in Section 232.430. Section 232.450(b) specifies
    that a source must retain records upon which the data included in the emissions report is based
    for a minimum period of three years, and must make these records available to the Agency
    upon request.
    Section 232.460 requires a source to correct any errors in the data previously submitted
    within 60 days of discovering such error.
    Subpart E: Listing and Delisting
    Section 232.501 contains an explanation for the inclusion of the chemicals and
    compound listed as HAPs under Section 112(b) of the CAA and for the inclusion of the “Great
    Waters” program targeted compounds under Section 112(m) of the CAA, and that these new
    compounds are exempt from the listing requirements of Section 232.500(b).
    Section 232.Appendix A List of Toxic Air Contaminants
    Appendix A has been amended to add the HAPS and Great Waters TACs not
    previously listed, and to denote the compounds as either HAPs, Great Water TACs, or both.
    Furthermore, Appendix A has also been revised to correct typographical errors and errors in
    the Chemical Abstract Service (CAS) numbers for previously listed chemicals.
    SUMMARY OF PUBLIC COMMENTS
    For a discussion of the public comments received in this matter during the rulemaking
    process see our Second Notice opinion adopted on March 20, 1997.
    SUMMARY OF THE REQUESTED JCAR CHANGES
    The Board, at the request of JCAR, adopted the following changes between Second
    Notice and today's Final Rule.
    The subsections labels a), b) and c) were deleted from the definition of "Commercial Fuel"
    in Section 232.120.
    In the definition of "Illinois Toxic Air Contaminant" the reference to the Clean Air Act
    was changed by deleting "as amended" and adding "(1990)".
    In the definition of "LC50", "fifty percent" was deleted and replaced with "50%".
    In the definition of "LD50","fifty percent" was deleted and replaced with "50%".
    In the definitions "Manufacture", "Otherwise use" and "Process" we deleted the phrase
    "Sections 232.400 through 232.460" and replaced it with "Subpart D".

    5
    In the definition of "NTP" we deleted the apostrophe connected to the phrase "United
    States".
    In Section 232.410(b)(4) we added a semicolon at the end of the "35 Ill. Adm. Code
    201.146".
    In Section 232.410(b)(5) we made the phrase "Commercial and Non-Commercial"
    lower case.
    Also in Section 232.410(b)(5) we changed "Illinois Administrative" to "Ill. Adm.".
    In Section 232.410(b)(6) we again changed the phrase "Illinois Administrative" to "Ill.
    Adm." and corrected the spelling of "agrichemical".
    In Section 232.410(c) we changed "one percent" to "1%" and "one-tenth of one
    percent" to ".1%".
    In Section 232.420(b) we capitalized "Section" before "232.430".
    In Section 232.430 we combined subsections (a)(1) and (2) to read as follows:
    (a)(1)
    Source identification information and the source's actual annual
    emissions of each ITAC (identified by generic name and Chemical
    Abstract Service (CAS) number) expressed in tons per year (TPY), and
    the source's annual fugitive emissions of each ITAC, expressed in TPY,
    for each ITAC that exceeds the threshold for applicability as set forth in
    Section 232.410 of this Part. In determining the actual annual emissions
    of each ITAC, the source may exclude emissions of such ITAC from all
    emission units with de minimis emissions of ITACs; or
    As a result of combining the old (a)(1) and (2), the old Section 232.430(a)(3) has
    become at Final Notice Section 232.430(a)(2). Additionally, we changed old Section
    232.430(a)(3) by capitalizing "Know" in the phrase "Emergency Planning and
    Community Right to Know Act". We changed the phrase "Subsections (a)(1) and (2)
    of this section" to "subsection (a)(1) of the Section". Finally, in the last sentence of
    Section 232.430(a)(3), now Section 232.430(a)(2), we changed the phrase "subsections
    (a)(1) and (2)" to "subsection (a)(1) of this Section".
    In Section 232.430(c) we deleted "January 1, 1996" and replaced with "the effective
    date of this Subpart". JCAR felt that this was unclear as to when sources were required
    to file reports for the first time and may be retroactive. At Second Notice, due to the
    timing of the final adoption of these rules, we changed the filing date for reports to be
    October 1, 1997. If the change in Section 232.430(c) was not made certain sources

    6
    may be required to file prior to that October 1, 1997 filing date. As such we thought it
    appropriate to make the change.
    Additionally, in Section 232.430(c) we changed the phrase "subsections (a)(1), (a)(2),
    or (a)(3)" to "subsections (a)(1) or (a)(2)" and deleted "of this Part" after "Subpart D"
    in the last sentence.
    In Section 232.430(e) we deleted "of this Part" after "Subpart D" in the last sentence.
    In Section 232.430(f) we added "this" after "under" in the last sentence and deleted "of
    this Part".
    In the first sentence of Section 232.501 we deleted "as amended" and replaced with
    "(1990)".
    In Appendix A we changed "3,4 Benzofluoronthene" to "3,4 Benzofluoranthene".
    CONCLUSION
    The Board today adopts a rule which will implement parts of Section 9.5 of the Act.
    Specifically, by today's action the Board will be implementing Section 9.5(c) of the Act which
    will allow the Agency after the review of the information gathered on Illinois ITAC emissions
    propose rules concerning the control of such emissions as set forth in Section 9.5(d) of the
    Act.

    Failure to receive the ITAC Source Report from the Agency shall not relieve an owner or
    operator from the obligation to file a complete emissions report. Any owner or operator who
    does not receive the ITAC Source Report on or before July 1, 1997, may contact the Agency to
    request the ITAC Source Report.
    (Source: Added at 21 Ill. Reg. _____, effective ______________.)
    Section 232.430
    Emissions Report
    a)
    On or before October 1, 1997, the owner or operator of a source subject to this
    Subpart shall file an emissions report for the calendar year 1996 which shall
    include the following information:
    (1)
    Source identification information and the source's actual annual
    emissions of each ITAC (identified by generic name and Chemical
    Abstract Service (CAS) number) expressed in tons per year (TPY), and
    the source's annual fugitive emissions of each ITAC, expressed in TPY,
    for each ITAC that exceeds the threshold for applicability as set forth in
    Section 232.410 of this Part. In determining the actual annual emissions
    of each ITAC, the source may exclude emissions of such ITAC from all
    emission units with de minimis emissions of ITACs; or
    2)
    If the owner or operator of a source subject to this Subpart so elects, the
    owner or operator may choose to submit the relevant portions of the

    13
    USEPA's Emergency Planning and Community Right to Know Act
    (EPCRA) Form R in lieu of the report required under subsection (a)(1) of
    this Section. If the owner or operator so elects, the reporting of emissions
    under Form R may be reported in pounds per year rather than in tons per
    year (TPY) as required in subsection (a)(1) of this Section.
    b)
    The following emissions of ITACs shall be considered to be de minimis and shall
    not be subject to reporting requirements under this Subpart:
    1)
    Emissions of ITACs from an emission unit which, in the aggregate, are less
    than one-half (0.5) TPY;
    2)
    Emissions from a process unit resulting from a process vent stream with
    ITAC concentrations that are always less than one-tenth of one percent
    (0.001) by weight on a daily basis, if such concentrations include any
    carcinogen listed in Appendix C of this Part;
    3)
    Emissions from a process unit resulting from a process vent stream with
    ITAC concentrations that are always less than one percent (0.01) by weight
    on a daily basis, if such concentrations do not include any carcinogen listed
    in Appendix C of this Part; or
    4)
    Fugitive emissions of ITACs from a process unit which, in the aggregate,
    are less than one-half (0.5) TPY.
    c)
    If a source becomes subject to this Subpart on or after the effective date of this
    Subpart, the owner or operator of the source shall submit an emissions report to
    the Agency on or before July 1 of the year following the date the source becomes
    subject to this Subpart for the period from the date the source first becomes
    subject to this Subpart through the end of the calendar year before the year the
    first report from such source is due under this Subpart. Such emissions report
    shall contain all of the information listed in subsections (a)(1) or (a)(2) of this
    Section and any additional information requested by the Agency pursuant to
    Section 232.450 of this Part. Any such emissions report shall satisfy the
    requirements Subpart D of this Part.
    d)
    An owner or operator of a source subject to this Subpart shall submit to the
    Agency a revised emissions report on or before July 1 of the year following the
    occurrence of any of the following:
    1)
    If the source's actual annual emissions of any individual ITAC or any
    combination of ITACs required to be reported under this Subpart increases
    by more than one-half (0.50) TPY or one (1) TPY, respectively, from the
    sources' emissions of ITACs initially reported under this Subpart; or

    14
    2)
    If the source emits an ITAC that exceeds the threshold for applicability as
    set forth in Section 232.410 of this Part which was not previously reported
    in the source's initial report of its emissions of ITACs or in any subsequent
    revised report of its emissions of ITACs required to be submitted pursuant
    to this subsection (d).
    e)
    Any revised emissions report required to be submitted under subsection (d) of this
    Section shall contain all of the information listed in subsection (a) of this Section
    and any additional information requested by the Agency pursuant to Section
    232.450 of this Part. Any revised emissions report shall satisfy the requirements of
    Subpart D.
    f)
    By July 1 of the calendar year following any modification or change to an emission
    unit requiring a revision to an existing permit or a new permit which may result in
    an increase in emissions of a previously reported ITAC by ten percent (.10) or
    more, an owner or operator of a source subject to this Subpart shall submit to the
    Agency a revised emissions report which includes the information required under
    this Section 232.430.

    Section 232.440
    Use of Available Data
    a)
    In order to provide the information requested by the Agency pursuant to Section
    232.450 of this Part, the owner or operator of a source may:
    1)
    Use reasonable engineering estimates of total emissions of individual
    ITACs pursuant to an emissions determination method, if, in each case, the
    owner or operator of a source specifies the emissions determination
    method used to estimate total emissions and certifies that such data
    represents the best available information and is true and accurate to the
    best of his/her knowledge; or
    2)
    If available, use monitoring or measuring data collected pursuant to other
    provisions of law or regulation.
    b)
    Nothing in this Subpart requires the monitoring or measurement of the quantities,
    concentrations, or frequency of emissions of any ITAC beyond any monitoring or
    measurement required under other provisions of law or regulation.

    Section 232.450
    Retention of Records/Additional Information
    a)
    For purposes of modeling and conducting assessments of information submitted
    under this Subpart, the Agency may request supporting documentation or
    additional information for any emissions report submitted by a source, including:
    1)
    An identification by generic name and Chemical Abstract Service (CAS)
    number the source’s emissions of each ITAC by emission unit, with
    maximum hourly emission rates in lbs/hr and actual annual emissions in
    TPY and the source's fugitive emissions of each ITAC in TPY;
    2)
    Operating data, exhaust point information and, if applicable, control device
    information for each emission unit; and
    3)
    Copies of engineering estimate calculations, mass balance calculations, and
    any other information or documentation used by the owner or operator of a
    source in preparing an emissions report.
    b)
    All records and calculations upon which the data submitted in the emissions report
    are based must be retained by the source for a minimum of three (3) years
    following the filing of a complete report. The owner or operator of a source shall
    provide the requested information in a format acceptable to the Agency within 60
    days after the receipt of the request.
    c)
    Nothing in this Section shall be interpreted to impose upon any source subject to
    this Subpart any additional monitoring which is not otherwise required by
    applicable rules or a permit condition.
