    PROPOSED RULE
    FIRST NOTICE
    OPINION AND ORDER OF
    THE
    BOARD by
    (B.
    Forcade):
    This matter comes before the Board on a regulatory proposal
    filed on January
    10,
    1991 by the Illinois Environmental
    Protection Agency (“Agency”)
    concerning the PM—lO emission limits
    for the portland cement manufacturing plant and associated quarry
    operations located
    in LaSalle County,
    Illinois.
    The proposed
    regulations are applicable
    to a single facility owned and
    operated by Lone Star Industries
    in Oglesby,
    Illinois,
    who agrees
    with the Agency’s proposed regulations.
    The proposed regulatory
    changes would amend Part 212, Visible and Particulate Matter
    Emissions,
    35
    Ill. Adm. Code 212.110, 212.423, and 212.424, and
    Part 211, Definitions General Provisions,
    35
    Ill.
    Adm. Code
    211
    122.
    The Agency has certified,
    and USEPA has confirmed and
    certified,
    that the proposed rule
    is a federally required rule as
    defined in Section 28.2(a) of the Illinois Environmental
    Protection Act
    (“Act”).
    Section 28.2 was amended by P.A.
    86—
    1409, effective January
    1,
    1991,
    requiring the Board to accept or
    reject an Agency certification within
    45 days.
    If the Board does
    not act within
    45 days,
    the certification shall be deemed
    granted.
    The Board notes that the new statute conflicts somewhat
    with the Board’s procedural
    rules governing Agency certifications
    (see
    35
    Ill. Adm. Code 102,
    Subpart F),
    but finds that the new
    statutory provisions govern this proceeding.
    USEPA established the National Ambient Air Quality Standards
    (“NA~QS”) for PM—b
    in 1987.
    The 24—hour PM—lB standard is
    150
    ug/m
    and the annual PM—b
    standard
    is
    50 ug/m
    .
    See
    52 FR 24634
    (July
    1,
    1987).
    These standards were authorized pursuant to
    Sections 108 and 109 of the Clean Air Act,
    42 U.S.C.
    7408,
    7409.
    Section 110 of the Clean Air Act requires that a State
    Implementation Plan (“SIP”)
    be adopted to achieve federal air
    quality standards.
    42 U.S.C.
    7410.
    The proposed rule before the
    Board
    is intended to satisfy the federal requirements for
    a SIP
    for PM—l0
    for the Oglesby,
    Illinois area,
    which area
    is
    designated as a
    “moderate” nonattainment area, based on past air
    quality violation.
    See
    55 FR 45799.
    The 1990 Clean Air Act
    Amendments require submission of a PM—lO SIP by Illinois by
    119—225

    —2—
    November
    15, 1991.
    The Board hereby accepts this regulatory
    proposal as
    a “required rule” under Section 28.2 of the Act.
    In order to expedite the regulatory proceeding,
    the Board
    is
    proposing this rulemaking for First Notice prior to hearing and
    without reaching a conclusion on the substance of the rule.
    The
    Board is proposing amendments
    to Parts 211 and 212 essentially as
    submitted by the Agency.
    The Board has made a number
    of non—
    substantive changes
    in preparation for review of the proposed
    rule by the Administrative Code Division of the Secretary of
    State’s Office and by the Joint Committee on Administrative Rules
    (“JCAR”).
    The Board has made particular efforts
    to clarify any
    references to applicable standards or limitations
    to satisfy JCAR
    concerns for specificity and to use a format
    for incorporations
    by reference which JCAR recently approved in R87-31.
    The Board
    has attempted to preserve the intent of the Agency’s proposal
    while yet anticipating probable revisions that could otherwise
    pose delays in adopting the final rule well
    in advance of the
    Agency’s November 1991 deadline.
    The participants will also note that certain terminology was
    changed and sections were reorganized by the Board.
    The Agency
    proposed Section 212.108, Test Methods for PM—b
    Emissions,
    but
    the Board instead proposes
    to amend current Section 212.110,
    Measurement Methods,
    as a prefered long-term organizational
    structure.
    Similarly,
    the Board repositioned the tests proposed
    by the Agency for placement in Section 212.423(f) to Section
    212.110.
    The Board deleted references
    to “fugitive dust”
    as this term
    is not defined
    in Part 211, and instead used the term
    “particulate matter”, which
    is found in Part
    211.
    Revisions were
    also made to clarify the sections on recordkeeping and
    reporting.
    The participants are invited to comment on the
    affirmative duties
    in proposed sections 212.423(e)(2) and
    (4) and
    212.424(e).
    The Board
    is interested
    in whether these duties can
    be summarized and consolidated so that recordkeeping and
    reporting responsibilities are readily identified
    in a single
    section
    in Part 212.
    The Board notes that Method
    202
    is currently proposed at
    55
    FR 41546,
    (October 12,
    1990).
    If Method 202
    is adopted by USEPA
    prior
    to the completion of this proceeding,
    the Agency proposes
    to adopt
    the final version of Method 202, with incorporation by
    reference of
    40 CFR
    51, Appendix M, Method
    202.
    The Board requests comments on the following language
    proposed by the Agency:
    1)
    The reference
    in
    Section 212.110(1)
    to USEPA’s
    continuing,
    independent authority.
    119—2
    26

    —3—
    2)
    The reference
    in Section 212.424(b)
    to Subpart K of this
    Part.
    3)
    The sentence
    in Section 2l2.424(e)(5) which states,
    “This report shall include those
    times when subsection
    (e) of this Section is involved.”
    4)
    The reference in Section 212.423(a)
    to the applicability
    of Sections 212.321 and 212.322 and the impact these
    sections may have on the requirement of no visible
    emissions found
    in Section 212.423(c)
    5)
    The reference in Section 212.423(a) to the applicability
    of Section 201.149.
