    PROPOSAL FOR PUBLIC COMMENT.
    PROPOSED OPINION
    AND
    ORDER OF THE BOARD
    (by J. Anderson):’
    This proceeding updates various provisions of Parts 203,
    211,
    215,
    218, and 219 to reflect the most recent pronouncement
    of TJSEPA’s “Recommended Policy on the Control of Volatile Organic
    Compounds.”
    In effect, this docket completes the amendments
    effected in R91—1O, effective October 11,
    1991.
    In that
    proceeding,
    the Board amended the Part 211 and 215 rules by our
    September 12,
    1991 Opinion and Order in response to USEPA addi-
    tions to the list of chemicals exempted from the definition of
    volatile organic materials
    (VOMs)
    ~2
    At 56 Fed. Reg.
    11418, March
    18,
    1991, USEPA added five compounds and four classes of com-
    pounds to the list of negligibly photoreactive compounds exempt
    from regulation under state implementation plans
    (SIPs).
    Those
    compounds constituted additions to those compounds exempted in
    R89—8, effective January
    1,
    1990.
    USEPA simultaneously proposed
    codification of the list at 56 Fed. Reg.
    11387,
    on March 18,
    1991.
    USEPA has now codified these exemptions effective March
    4,
    1992.
    57
    Fed. Reg.
    3941
    (Feb.
    3,
    1992).
    Unaffected by the R91-l0 rulemaking,
    and as discussed in the
    Board’s Opinion and Order in that matter, were the definition of
    “volatile organic compound” at 35 Ill.
    Adm. Code 203.145 and the
    definitions of “volatile organic material” at recently-adopted
    Sections 218.104 and 219.104.
    Part 203 sets forth the rules
    applicable to construction and modification of major stationary
    sources.
    Part 218 governs emissions of volatile organic material
    from stationary sources located in the Chicago metropolitan area
    (Cook, DuPage,
    Kane, Lake, McHenry and Will counties)

    governs the emissions of volatile organic material from
    stationary sources located in the metropolitan East St. Louis
    area (Madison, Monroe, and St. Clair counties).
    The Board
    reserved this docket during the pendency of R91-10 in order to
    complete the amendments to Parts 203,
    218, and 219, which were
    not affected by that matter.
    This proceeding extends the
    exemption to include all federally—exempted compounds for all
    organic emissions from stationary sources in Illinois.
    The~Board adopts this Proposed Opinion and Order pursuant to
    the identical-in-substance mandate under Section 9.1(e)
    of the
    Environmental Protection Act, Ill.
    Rev.
    Stat.
    1989,
    ch.
    111½,
    par. 1009.1(e).
    Section 9.1(e) provides for quick adoption of
    regulations that are “identical in substance” to certain pub-
    lished federal policy statements.
    It further provides that Title
    VII of the Act and Section 5 of the Administrative Procedure Act
    (APA)
    shall not apply.
    Because this rulemaking
    is not subject to
    Section 5 of the APA, it is not subject to first notice or to
    second notice review by the Joint Committee on Administrative
    Rules
    (JCAR).
    The primary Federal Register citation to the revision in the
    federal policy statement used in this Opinion and Order is as
    follows:
    57 Fed.
    Reg. 3942
    February 3,
    1992
    (amending 40
    CFR 51.100(s)
    (definition of
    “volatile organic compound”),
    effective March
    3,
    1992).
    This proceeding is also based on the following Federal Register
    citation:
    56 Fed. Reg.
    11418
    March 18,
    1991.
    The March 18,
    1991 revision to USEPA’s “Recommended Policy
    on the Control of Volatile Organic Compounds” added five
    compounds and four classes of compounds to the list of
    negligibly-photochemically-reactive compounds exempted from
    regulation as volatile organic compounds.
    The February 3,
    1992
    action codified the existing USEPA policy, by adoption of the 40
    CFR 51.100(s) definition of “volatile organic compound.”
    USEPA
    simultaneously withdrew its recommended policy as moot on
    February 3,
    19.92.
    57 Fed. Reg. 3943
    (Feb.
    3,
    1992).
    In the course of codifying its policy, USEPA clarified it.
    USEPA added language that excludes
    a number of carbon compounds
    from the definition.
    USEPA clarified the monitoring requirement
    for exempted compounds and added specificity to the methods for
    testing for those compounds.

    This docket.
    The Federal Register issues included in each docket are recited
    in that respective Opinion and Order.
    PUBLIC COMMENTS
    The Board invites public comments on the proposed
    -~
    amendments.
    We will receive public comments until at least 45
    days after Notices of Proposed Amendments appear in the Illinois
    Register on this matter.
    Section 7.2 and 9.1(e)
    of the Act
    provide that this proceeding is not subject to Section
    5 of the
    Administrative Procedure Act
    (Ill. Rev.
    Stat.
    1989 ch.
    127, par.
    1005).
    Therefore,
    it is not subject to First Notice or Second
    Notice review by the Joint Committee on Administrative Rules.
    After the 45 day public comment period has expired,
    the Board
    will promptly proceed to adopt amendments based on today’s
    proposal.
    DISCUSSION
    At 56 Fed. Reg.
    11418, March 18,
    1991,
    USEPA announced a
    change in its “Recommended Policy on the Control of Volatile
    Organic Compounds,” adding five halocarbon compounds and four
    classes of perfluorocarbon compounds to the list of negligibly
    photoreactive compounds exempt from regulation under state
    implementation plans.
    Those compounds are as follows:
    1.
    2-chloro-1, 1,1,2—tetrafluoroethane (HCFC—l24)
    2.
    Pentafluoroethane (HFC-125)
    3.
    1,1, 2,2—tetrafluoroethane (HFC—134)
    4.
    1,1,1-trifluoroethane (HFC—143a)
    5.
    1,l-difluoroethane (HFC-152a)
    Those classes of compounds are as follows:
    130—459

    4
    1.
    Cyclic,
    branched, or linear, completely fluorinated
    alkanes.
    2.
    Cyclic,
    branched, or linear, completely fluorinated
    ethers with no unsaturations.
    3.
    Cyclic,
    branched,
    or linear, completely fluorinated
    tertiary amines with no unsaturations.
    -
    4.
    Sulphur—containing perfluorocarbons with no unsatura—
    tions and with sulfur bonds only to carbon and fluo-
    rine.
    Under this policy,
    states may not take credit for controlling
    these compounds in their ozone state implementation plans
    (SIPS).
    USEPA simultaneously proposed to amend the federal implementation
    plan
    (FIP)
    for Chicago and to amend 40 CFR 51 to add a general
    definition of VON consistent with its policy revision.

    Section 9.1(e)
    Mandate
    In R9l-10, the Board raised the issue of what impact the
    federal adoption of the exemptions as a rule and accompanying
    withdrawal of the recommended federal policy would have on its
    Section 9.1(e)
    mandate.
    After a full discussion of this issue,
    the Board determined that the Section 9.1(e) mandate would apply
    to a codified policy because the heart of the mandate is the
    language:
    “The Board shall exempt from regulation under the
    State Implementation Plan for ozone the volatile organic
    compounds which have been determined by the U.S. Environmental
    Protection Agency to be exempt from regulation under state
    implementation plans for ozone due to negligible photochemical
    reactivity.”
    Ill. Rev.
    Stat.
    1989 ch.
    111½,
    par.
    1009.1(e).
    The
    Board determined that the statutory language relating to “the
    U.S. Environmental Protection Agency exemptions or deletion of
    exemptions published in policy statements on the control of
    volatile organic compounds in the Federal Register
    .
    .
    .,“
    Ill.
    Rev.
    Stat.
    1989,
    ch.
    111½,
    par. 1009.1(e),
    further authorized us
    to employ an “unorthodox,” non—codified source for as basis of
    the exemptions.
    Opinion and Order of September 12,
    1991 in R91-
    10 at 5-7.
    The Board concluded as follows:
    Under this analysis, the clear intent of the
    General Assembly is that the Board must adopt the
    federal exemptions by identical—in—substance
    rulemaking.
    The mandate that the Board apply federal
    130—460

    5
    policy statements to this end is further authorization
    to base those regulations on their presently—existing
    sole source:
    federal policy statements.
    If USEPA
    chooses to employ the more conventional regulatory
    approach of codifying the exemptions,
    the mandate
    remains that the Board must adopt those exemptions by
    identical-in—substance procedures.
    The Board believes that this is the interpretation
    th~twill best implement the intent of the General
    Assembly as embodied in Section
    9.1(e).
    If the Board
    errs in its assessment, the General Assembly is free to
    further clarify its intent by later legislative
    amendment.
    However, the Board believes that by
    proceeding with this rulemaking despite USEPA’s
    prospective change
    in approach, we will achieve the
    benefits for Illinois industry that the General
    Assembly desires, and we will attain greater consis-
    tency with the federal scheme for ozone control.
    Therefore, the Board is adopting the proposed
    -
    amendments without regard to the possibility that USEPA
    will likely moot the federal policy statement upon
    which it is based.
    The possibility exists that the
    Board will face the prospect of basing future
    amendments on federal rules, rather than on the policy
    statements referred to in Section 9.1(e).
    The Board.
    will address that issue when it arises.
    Opinion and Order of September 12,
    1991 in R9l-10 at 7-
    8.
    The intervening codification of the recommended federal
    policy now confronts the Board with this issue.
    Without further
    elaboration of the reasons set forth in R9l-lO, the Board hereby
    determines that Section 9.1(e) mandates that we adopt the revised
    policy on negligibly—reactive compounds based on the codified
    USEPA exemptions from its definition of “volatile organic
    compound”
    (the same as “volatile organic material”
    in the
    Illinois Part 211,
    215,
    218, and 219 regulations)
    at 40 CFR
    51.100(s).
    This is despite the USEPA withdrawal of its
    recommended policy as a result of the adoption of this definition
    as a regulation.
    Parts Affected
    In R91-10, the Board discussed the Agency observation that
    amendment of the Section 211.122 definition of VON did not affect
    the corresponding definitions of “volatile organic compound,” at
    Section 203.145, and “volatile organic material,” at Sections
    130—461

    6
    218.104 and 219.104.~ Since Parts 218 and 219 became effective
    after the publication of the Notice of Proposed Amendments for
    R91-10, the Board could not include amendment of those Parts
    in
    that docket without causing significant delay.
    In fact,
    the
    Agency advocated delay in that docket until USEPA adopted the
    proposed 40 CFR 51.100(s) definition.
    The Board concluded that
    this did not warrant delay in the R91-10 proceeding.
    ~
    Opinion and Order of September 12,
    1991 in R91-10 at 8—10.
    Rather, we reserved this docket to accomplish the amendment of
    Parts
    20,3,
    218,
    and 219 to reflect the revised federal
    recommended policy.
    USEPA has now codified its policy on negligibly-reactive
    compounds.
    Therefore, the Board proceeds to harmonize the
    definitions of VON appearing at Parts 203, 211,
    218, and 219.
    Further,
    TJSEPA effected some minor clarifications of its
    recommended policy in the Federal Register preamble accompanying
    the adoption and in the text of the new definition of “volatile
    organic compound.”
    The clarifications relate to exclusions of
    certain inorganic carbon compounds
    (i.e., the inclusion of only
    “organic” carbon compounds),
    the monitoring requirement,
    and
    state and federal authority to require monitoring.
    These.
    clarifications warrant re—examination of the R91—l0-amended
    Section 211.122 definition and Section 215.109 monitoring
    requirement.
    Federal Clarification of “Organic”
    At 40 CFR 52.741(a),
    USEPA has a definition of “organic
    material.”
    This definition excludes certain carbon compounds
    that are not organic.
    On February 3,
    1992, USEPA excluded
    certain of these compounds from the definition of “volatile
    organic compound” with the following language:
    “any compound of
    carbon, excluding carbon monoxide, carbon dioxide, carbonic acid,
    metallic carbides and carbonates, and ammoniuin carbonate.”
    40
    CFR 51.100(s),
    as added at 57 Fed. Reg.
    3945
    (Feb.
    3,
    1992)
    (effective March
    3,
    1992).
    This added language is identical to the Illinois definition
    of “organic compound,” and essentially similar to parallel
    language in the definitions of “organic material,” as presently
    codified at 35
    Ill. Adm. Code 211.122, 218.104,
    and 219.104.
    The
    As
    previously
    noted,
    Part
    203
    sets
    forth
    the
    rules
    applicable
    to construction and modification of major stationary
    sources;
    Part
    218
    governs
    emissions
    of
    organic
    material
    from
    stationary sources located in the Chicago metropolitan area (Cook,
    DuPage,
    Kane,
    Lake,
    McHenry
    and
    Will
    counties);
    and
    Part
    219
    governs the emissions of organic material from stationary sources
    located in the metropolitan East St. Louis area
    (Madison, Monroe,
    and St. Clair counties).
    130—462

    7
    definitions of “volatile organic material,” also at these
    Sections, depend on the definition of “organic compound” in such
    a way that there
    is no need for the Board to add language to•
    further clarify any of these three definitions.
    The Section
    203.145 definition of “volatile organic compound”
    includes, inter
    alia, exclusion of “carbon monoxide, carbon dioxide, carbonic
    acid, metal carbides, -metal carbonates,
    (and
    ammonium carbonate
    ..“
    Therefore,
    no revision of this Section is required by
    this federal clarification.
    The Fed~eralMonitoring Requirement
    The codification of the USEPA policy in the definition of
    “volatile organic compound” at 40 CFR 51.100(s) raises issues
    related to the monitoring requirement.
    In adopting R91-10, the
    Board embodied its best understanding of the previously-
    enunciated USEPA policy relating to the occasional need to
    monitor for negligibly—reactive compounds.
    The Board observed
    that there were certain circumstances under which USEPA stated
    that monitoring might be required as a precondition to a
    compound’s exemption.
    However, we noted that Senn Park Nursing
    Center v. Miller,
    118 Ill. App.
    3d- 504,
    455 N.E.2d 153
    (1st Dist.
    1983), aff’d 104 Ill.
    2d 169, 470 N.E.2d 1069
    (1984), would
    require codification of any authority to require any such
    monitoring.
    In conclusion, we codified the USEPA—enumerated
    circumstances that would necessitate monitoring:
    (Where
    direct quantification of volatile organic material emis-
    sions is not possible due to any of the following circumstances
    which make it necessary to quantify the exempt compound emissions
    in order to quantify volatile organic material emissions:
    a)
    VOM5 and exempted compounds are mixed together in the
    same emissions;
    b)
    There are a large number of exempted compounds in the
    same emissions;
    or
    C)
    The chemical composition of the exempted compounds in
    the emissions is not known.
    35 Ill. Adm. Code 215.109; see R91-10 Opinion and Order
    of September 12,
    1991 at 15—16.
    In the codified policy, USEPA authorizes the states to
    require monitoring for the exempted compounds.
    Whether or not
    Illinois reserves the authority to require monitoring, USEPA
    reserves the right to require such monitoring that demonstrates
    the amount of exempt compounds in a source’s emissions.
    USEPA
    states as follows in the new definition of VON:
    (2)
    For purposes of determining compliance with
    130—463

    8
    emissions limits,
    VON
    will be measured by the
    test methods in the approved State implementation
    plan
    (SIP)
    or 40 CFR part 60, appendix A,
    as
    applicable.
    Where such a method also measures
    compounds with negligible photochemical
    reactivity, these negligibly-reactive compounds
    may be excluded as
    (VOM
    if the-amount of such
    compounds is accurately quantified, and such
    exclusion is approved by the
    (state.
    (3)’
    As a precondition to excluding these compounds as
    VOM
    or at any time thereafter, the (state) may
    require an owner or operator to provide monitoring
    or testing methods and results demonstrating, to
    the satisfaction of the state,
    the amount of
    negligibly—reactive compounds in the source’s
    emissions.
    (4)
    For purposes of Federal enforcement for
    a specific
    source, the US)EPA
    shall use the test methods
    specified in the applicable EPA-approved SIP,
    in a
    permit issued pursuant to a program approved or
    promulgated under title V of the (federal Clean
    Air) Act,
    or under 40 CFR part 51, subpart
    I or
    appendix 5, or under 40 CFR parts 52 or 60.
    The
    (USEPA
    shall not be bound by any State
    determination as to appropriate methods for
    testing or monitoring negligibly-reactive
    compounds if such determination is not reflected
    in any of the above provisions.
    ,rnus, the purpose of the monitoring is to quantify VOMs,
    as the
    Board perceived in R91-10.
    Further, although USEPA is leaving to
    state discretion whether the state requires the source to monitor
    or whether the state itself monitors, USEPA will require the
    monitoring as needed to quantify VON5.
    ~
    57
    Fed.
    Reg.
    3944
    (Feb.
    3,
    1992).
    As to analytic methodology for analyses, the present
    Illinois definition of VOM refers to the methods incorporated by
    reference at 35 Ill.
    Adm. Code 215.105.~ That Section includes
    numerous references——among them is 40 CFR 60.
    If part of an
    approved SIP, the methods would satisfy the first segment of new

    We
    believe that no amendment is necessary to either Section 211.122
    (definition of VOM)
    or Section 215.105 incorporations by
    reference)
    on this basis.
    For these reasons, the Board believes that we accurately
    assessed the scope of the federal policy on September 12,
    1991
    in
    R91—10.
    No amendment to any Section is necessary based on
    further federal elaboration of its policy.
    However, one option
    open to~theBoard is to simply delete the circumstances
    enumerated as subsections
    (a) through
    (c).
    The
    Board invites
    public comment as to whether the existing regulatory language
    adequately embodies USEPA’s codified policy and intent.
    In
    addition-to the amendments to Sections 203.145,
    218.104, and
    219.104, the Board will open the monitoring provision at 35
    Ill.
    Adin.
    Code 215.109 by proposing a minor amendment.
    This will
    allow subsequent amendment if public comments indicate the need
    to do so.
    The minor amendment that the Board proposes
    is to add--a
    Board Note to Section 215.109 that will direct the attention of
    the regulated community to the federal definition at 40 CFR
    51.100(s) (2) through
    (s)(4).
    In particular,
    this Board Note will
    direct attention to federal paragraph
    (s) (4) and 57 Fed.
    Reg.
    3944
    (Feb.
    3,
    1992),
    in which USEPA makes it clear that it
    remains not bound by state determinations as to monitoring for
    negligibly—reactive compounds.
    Amendments to Section 203.145
    The Section 203.145 definition of “volatile organic
    compound” applies only within Part 203.
    The Board adopted it
    March 10,
    1988 in R85—10, effective March 22,
    1988.
    The words
    “volatile organic compound” appear in Sections 203.206(b)
    (“major
    stationary source”), 203.207(b)
    (“major modification of a
    source”), 203.209(e)
    (significant emissions determination),
    203.303(d) (3) and
    (e)
    (baseline emissions offsets
    determinations), and 203.306
    (analysis of alternative sites,
    processes,
    controls, etc.).
    This definition is identical to the
    Part 211 definition of “volatile organic material” with three
    major exceptions:
    1.
    The Section 203.145 definition includes within its own
    terms both the compounds exempted from the Section
    211.122 definitions of “organic material”
    (as not
    “organic”)
    and “volatile organic material”
    (as
    negligibly-reactive),
    2.
    The Section 203.145 definition does not refer to
    analytical procedures for quantification of volatile
    species
    (rather,
    this provision refers to volatility);
    and
    130—465

    -
    10
    3.
    Section 203.145 does not include several negligibly
    reactive compounds exempted from the Section 211.122
    definition in R89—8
    (October 18,
    1989)
    and R9l-10
    (September 12,
    1991):
    from R89—8:
    chiorodifluoroethane (HCFC—142b)
    dichlorofluoroethane
    (HCFC-14ib)
    dichlorotrifluoroethane (HCFC-12 3)
    tetrafluoroethane (HFC-134a)
    from R91—1O:
    2—chloro—l, 1,1,2—tetrafluoroethane (HCFC-124)
    1, l-difluoroethane
    (HFC-152a)
    pentafluoroethane (HFC-l25)
    1,1, 2,2—tetrafluoroethane (HFC-134)
    1,1, 1—trifluoroethane (HFC—143a)
    The following classes of compounds:
    cyclic, branched,
    or linear, completely
    fluorinated alkanes;
    cyclic, branched,
    or linear, completely
    fluorinated ethers with no
    unsaturations;
    cyclic,
    branched,
    or linear, completely
    fluorinated tertiary amines with no
    unsaturations;
    sulphur—containing perfluorocarbons with
    no unsaturations and with sulfur bonds
    only to carbon and fluorine.
    The differences based on the unitary structure of Section
    203.145 are immaterial.
    The fact that the definition of
    “volatile organic compound” does not refer to a separate
    definition of “organic compound” does not affect its meaning.
    This structural difference does not affect the size of the
    regulated community or the activities that fall within the
    Board’s regulations.
    The differences based on references to analytical methods
    are not major,
    but they could potentially cause some entity to
    fall under the purview of Part 203 that is not subject to
    regulation under Part 215 or vice versa.
    Section 203.145 defines
    the objects of interest as “present in the atmosphere
    in a
    gaseous state.”
    Section 211.122 defines those objects for the
    purposes of Part 215)
    as “participat(ing
    in atmospheric
    photochemical reactions.”
    The purpose of the Section 203.145
    definition
    is permitting entities subject to regulation under
    Part 215.
    To the extent there a species that are “present in the
    atmosphere in a gaseous state”
    or “participat(ing
    in atmospheric
    photochemical reactions” but not both,
    there is a potential gap
    130—466

    11
    between the permit requLrement and the emissions limitations.
    It is interesting to note the extent of the changes made by
    USEPA in adopting its section 51.100(s) definition of “volatile
    organic compound.”
    USEPA simultaneously amended its sections
    51.165(a) (1) (xix),
    51.166(b) (29),
    and.part 51, appendix S
    (II)(A)
    lists of volatile organic compound exclusions to take the form of
    a definition of “volatile organic compound,” which states that
    the meaning of this term is given at section 51.100(s).
    40 CFR
    51.165 sets forth the federal permit requirements.
    Section
    51.166 sets forth the prevention of significant deterioration
    requirements.
    Appendix S
    is a clarification of the USEPA offset
    policy.
    These are all subjects within the scope of Part 203 of
    the Illinois rules.
    In adopting the definition of VON, USEPA
    stated that it intended only to codify existing policy and not to
    effect any substantive change.
    See 57 Fed. Reg. 3943
    (Feb.
    3,
    1992).
    Therefore,
    USEPA now employs the same definition of
    “volatile organic compound” for all purposes——for both permitting
    and for setting emissions limitations, and it is their apparent
    intent that this was always so.
    -
    The differences in the Section 203.145 and 211.122
    definitions relating to exempted compounds are the primary focus
    of this docket.
    The Section 203.145 definition includes all
    compounds exempted under the federal recommended policy as of the
    date of its adoption (March 10,
    1988).
    USEPA has since twice
    updated that policy
    (at 54 Fed.
    Reg.
    1987, January
    18,
    1989,
    and
    at 56 Fed. Reg.
    11418, March 18,
    1991).
    The Board followed suit
    by amending the Section 211.122 definition of “volatile organic
    material”
    in R89—8, October 18,
    1989 (effective October 27,
    1989), and R9l-10, September 12,
    1991 (effective October 11,
    1991).
    However, the Board did not amend the Section 203.145
    definition at those times.
    Rather, the Board reserved this
    docket for that purpose.
    Today, we propose amendments to 35 Ill.
    Adm. Code 203.145 that will have the effect of exempting all
    compounds from regulation under Part 203 that are also exempted
    from regulation under Part 215
    (and Parts 218 and 219).
    Since Part 203 sets forth the permitting requirements for
    activities regulated under Part 215
    (for which Section 211.122
    provides the operative definition of “volatile organic
    material”),
    the Board believes that the Section 203.145
    definition of “volatile organic compound” should have the same
    meaning that “volatile organic material” has for the purposes of
    Part 215.
    We believe that this is presently the case,
    but
    identical meaning is best accomplished through the same
    definitional language.
    The most efficient way to accomplish this
    is to place the definitional language in one location and refer
    to it from all other locations.
    This has the combined effects of
    more closely tracking the federal definition of “volatile organic
    compound” and exempting all negligibly—reactive compounds from
    state regulation as VONs.
    This also facilitates future
    130—46 7

    12
    amendments and minimizes the possibility of future oversight and
    the resulting discrepancies.
    For these reasons, the board proposes to amend Section
    203.145 so that “volatile organic compound,” for the purposes of
    Part 203, means “volatile organic material,” as that term is
    defined at Section 211.122.
    The Board does not take the
    additional step at this time of proposing the substitution of
    “volatile organic material” for “volatile organic compound” where
    that term appears at Sections 203.206(b),
    203.207(b),
    203.209(e),
    203.303(d) (3) and
    (e), and 203.306.
    The Board invites public
    comment as to whether this approach and the chosen language
    adequately embodies USEPA’s codified policy and intent.
    Amendments to Section 211.122
    The Board proposes amendment of the Section 211.122
    definition of “volatile organic material” to indicate the source
    of the exempted compounds.
    The Board adds a Board Note to this
    provision to reference the federal 40 CFR 51.100(s) definition of
    “volatile organic compound” and 57 Fed. Reg. 3941
    (Feb.
    3,
    1992),
    at which USEPA adopted
    it.
    The Note also references 35 Iii.
    Adin.
    Code 215.109, the monitoring requirement.
    The Board invites
    public comment on this approach to the codified USEPA policy and
    intent.
    Amendments to 215.109
    The Board proposes amendment of Section 215.109 to indicate
    the source of the monitoring requirement for negligibly—reactive,
    exempted compounds.
    The Board adds a Board Note to this
    provision to reference 56 Fed. Reg.
    11418
    (Mar.
    18,
    1991), when
    USEPA introduced the concept of such monitoring, and the federal
    40 CFR 51.100(s)
    definition of “volatile organic compound” and
    57
    Fed. Reg. 3941
    (Feb.
    3,
    1992), at which USEPA adopted it.
    The
    Note also references 35 Ill..Adm.
    Code 211.122, the definition of
    “volatile organic material.”
    The
    Board invites public comment
    on
    this approach to the codified USEPA policy and intent.
    Amendments to Sections 218.104 and 219.104
    As outlined above, Part 218 sets forth the rules applicable
    to emissions of volatile organic materials in the greater Chicago
    metropolitan area,
    and Part 219 sets forth the rules applicable
    for those emissions in the East St. Louis metropolitan area.
    Each Part became effective on August 16,
    1991 (by Board orders of
    July 25,
    1991,
    in R91—7 for the Chicago area and R91-8 for the
    130—468

    13
    East
    St.. Louis area).6
    Section 218.104 sets forth the definition
    of VOM for Part 218,
    and Section 219.104 sets forth the
    definition for Part 219.
    Both definitions use identical
    language, with the exception of some language in Section 218.104
    relating to the 3M Bedford Park facility, and both are
    essentially similar to the Section 211.122 definition of VOM
    prior to .the prior VON update, R91-10.
    The language at Section
    218.104 relating to the 3M facility exempts the classes of
    compounds exempted from the Section 211.122 definition in R91-10.
    The lan~uagein both Sections 218.104 and 219.104 relating to the
    treatment of the exempted compounds adds nothing to the language
    already at Section 211.122.
    For reasons similar to those recited for the Section 203.145
    amendments above, the Board believes that references at 35 Ill.
    Adm.
    Code 218.104 and 219.104 to the definition of VON at Section
    211.122
    is the preferred method of updating these definitions.
    This method assures not only that the present Part 215 exemptions
    become Parts 218 and 219 exemptions,
    it assures harmony in
    meaning of the same term for all areas of the state.
    -
    It also
    minimizes the likelihood of future disparity through subsequent
    updates.
    Therefore,
    we propose amendment of Sections 218.104 and
    219.104 so that “volatile organic material,” for the purposes of
    Parts 218 and 219, means “volatile organic material,”
    as that
    term is defined at Section 211.122.
    The Board invites public
    comment as to whether this approach and the chosen language
    adequately embodies USEPA’s codified policy and intent.
