    OF:
    )
    )
    RCRA UPDATE, USEPA REGULATIONS
    )
    R88-16
    (1-1-88 THROUGH 7-31-88)
    )
    FINAL ORDER.
    ADOPTED RULE
    OPINION OF THE BOARD
    (by J.
    Anderson):
    By a separate Order, pursuant
    to Section
    22.4(a) of the Environmental
    Protection Act
    (Act), the Board
    is
    amending the RCRA hazardous waste
    regulations.
    Section 22.4 of the Act governs adoption of regulations establishing the
    RCRA program
    in
    Illinois.
    Section 22.4(a) provides for quick adoption of
    regulations which are “identical
    in
    substance”
    to federal
    regulations;
    Section
    22.4(a) provides that Title VII of the Act and Section
    5 of the
    Administrative Procedure Act shall
    not apply.
    Because this rulemaking
    is not
    subject
    to Section
    5 of the Administrative Procedure Act,
    it
    is
    not subject
    to
    first
    notice
    or
    to second notice review by the Joint Committee on
    Administrative Rules (JCAR).
    The federal
    RCRA regulations are found
    at
    40 CFR
    260 through 270, and
    280.
    This rulemaking updates
    Illinois’
    RCRA rules
    to
    correspond with
    federal amendments during the period January
    1 through July
    31, 1988.
    The Federal Registers utilized
    are as
    follows:
    53 Fed. Reg. 13383
    April
    22,
    1988
    53 Fed. Reg. 27162
    July 19,
    1988
    53 Fed. Reg. 27164
    July 19, 1988
    53 Fed. Reg. 27289
    July 19,
    1988
    In R86—46 the Board
    passed over revisions to the chemical
    listings which
    appeared at
    51
    Fed. Reg.
    28298, August
    6,
    1986.
    The Board
    proposed these
    revisions
    in R87—39, but withdrew this portion
    of the proposal when
    it
    became
    apparent that the
    format
    of the April
    22 corrections would
    prevent timely
    adoption of the remainder of R87-39.
    The Board
    has
    now adopted the August 6,
    1986 revisions as
    corrected on April
    22,
    1988.
    The Board opened this Docket with
    the intention of addressing USEPA
    amendments during
    the six-month period
    from January through June.
    The Board
    has expanded
    the scope
    to
    include July,
    1988.
    This allows quicker adoption of
    the July 19 amendment which exempts treatibility studies from the RCRA
    program.
    The Board departed from the
    usual
    biannual
    update practice
    in this

    appreciates the assistance of Morton Dorothy
    in drafting
    the Order
    and Opinion.

    case because of the possible importance of the treatability exemption
    in
    acheiving compliance with the landfill
    bans, and because of the relatively
    small
    amount of material
    in the January through June period.
    5.8. 1834 amended the act
    to recognize the existing “batching”
    practice.
    As worded,
    S.B. 1834 prohibits
    the use of batches longer than
    six
    months.
    However,
    in that there were no amendments during January, 1988, the
    batch does
    not exceed
    six months.
    Section 7.2 of the Act,
    as adopted
    in 5.8.
    1834, codifies the Board’s longstanding interpretation of its mandate
    to adopt
    “identical
    in substance”
    regulations.
    (See R85—23, cited
    below,
    and R86-44,
    December 3,
    1987,
    pages
    14 and
    19.)
    During this period the Federal Register also included a large number of
    delistings.
    As provided by Section 720.122, the Board will
    not adopt
    site-
    specific delistings unless
    and until
    someone proposes that the Board
    adopt the
    delisting and demonstrates why the delisting
    is necessary
    in
    Illinois.
    PUBLIC COMMENT
    The Board
    adopted
    a proposed Opinion and Order on September 8, 1988.
    The
    proposal appeared on September 30,
    1988,
    at
    12
    Ill. Reg. 15327.
    The Board
    received the following public comment before and during the comment period:

    On July 22,
    1988,
    the
    Illinois Environmental Protection Agency
    (IEPA or
    Agency)
    filed
    a motion
    to
    reconsider the Board’s Opinion
    in R87—39.
    In that
    the motion did not directly address
    the text of the rules
    as adopted,
    and was
    not
    timely
    filed,
    the Board,
    on August
    4, 1988,
    declined to address
    it
    in that
    Docket.
    The Agency’s motion was made PC
    1
    in this Docket.
    As
    is discussed
    below,
    in
    that there
    is
    no definitive answer to
    the issues
    raised,
    and
    in that
    the
    issues
    do not directly relate to the text of the
    rules
    adopted
    in this
    Docket, the Board will
    again
    postpone decision
    on these
    issues.

    Most of the Order concerns the revisions to the chemical listings.
    USEPA
    adopted
    a supposedly non-substantive revision of the chemical listings in
    August, 1986.
    The Board noted
    a
    large
    number
    of
    apparent
    substantive
    changes
    to the listings, and declined to adopt the revisions pending clarification
    from USEPA.
    The Board
    reproposed the revisions
    in R87—39
    in anticipation of
    USEPA’s clarification.
    This came in April,
    1988,
    near the end
    of the public
    comment period
    in R87—39.
    The action took the form of revised lists, with no
    clues
    as
    to what the revisions were.
    The Board dropped the revisions from
    R87—39 since
    it
    looked like
    it would
    take far too long to translate the
    changes into Administrative Code format.
    The Board reproposed the revisions
    in this Docket.
    The problems with the
    farmer exception came about with the rules
    on
    exports of
    hazardous waste which were adopted
    in R87-5.
    USEPA
    renumbered the
    farmer exception to make room for
    a Subpart addressing exports of hazardous
    waste,
    and then
    inadvertently repealed portions of the export rules with some
    minor changes to the farmer
    exception.
    The Board
    noted many of these
    problems, and corrected them in R87-5
    and R87-39.
    DETAILED DISCUSSION
    Section 703.123
    This Section
    is drawn from 40 CFR 270.1(c)(2),
    which was amended
    at
    53
    Fed. Reg. 27164, July 19,
    1988,
    to correct
    a reference to the farmer exemption
    of Section 722.170.
    Section 720.110
    This Section was
    amended
    at
    53 Fed. Reg. 27289, July 19, 1988,
    to
    add
    a
    definition of “treatability study”.
    Section
    720.111
    USEPA is actually using
    a new edition of ASTM Setaflash Closed Tester
    method
    for determining flashpoint.
    (PC~3) The Illinois APA requires the
    Board
    to update the reference in the rules.
    The Board has therefore updated
    this reference
    to the
    1987 ASTM method.
    Section
    721.104
    This Section was
    amended
    at
    53 Fed. Reg. 27289, July
    19, 1988 to
    add two
    new exclusions from the definition of “hazardous waste”.
    Sections 721.104(e)
    and
    (f) exclude treatability study samples from the regulatory program.
    Treatability study
    samples
    are generally limited
    to 1000 kg of any non—
    acute hazardous waste,
    1
    kg of acute
    hazardous waste
    or 250 kg of soils, water
    or debris
    contaminated with acute
    hazardous waste.
    Section
    721.104(e)(3)
    allows the Agency to increase this quantity by
    up
    to 500
    kg
    of any non-acute
    hazardous waste,
    1
    kg
    of
    acute hazardous waste
    or 250 kg of soils, water
    or
    debris
    contaminated with acute hazardous waste
    if there
    is
    a
    need to repeat
    or
    verify
    a treatability study.
    93—518

    —7—
    There
    is
    a
    question
    as
    to
    whether
    the
    Board
    or
    Igency
    is
    the
    proper
    authority
    to
    approve
    increases
    in
    these
    amounts.
    While
    Section
    5
    of
    the
    Act
    requires
    the
    Board
    to
    “determine,
    define
    and
    implement
    the
    environmental
    control
    standards
    applicable
    in
    the
    State
    ...“,
    Sections
    4(g)
    and
    39
    require
    the
    Agency
    to
    administer
    permit
    systems
    established
    by
    the
    Act
    or
    Board
    regulations.
    If
    Board
    action
    were
    required,
    it
    could
    come
    by
    way
    of
    variance,
    provisional
    variance,
    rulemaking
    or
    adjusted
    standard.
    Board
    has
    decided
    that
    these
    are
    decisions
    that
    the
    Agency
    should
    make
    while
    applying
    Board
    rules
    in
    the
    context
    of
    the
    RCRA
    permit
    program.
    However,
    since
    the
    treatability
    studies
    are
    normally
    preliminary
    to
    an
    actual
    permit
    application,
    it
    is
    necessary
    to
    provide
    an
    appeal
    mechanism
    for
    Agency
    decisions.
    The
    Board
    has
    therefore
    added
    Section
    721.104(e)(4)
    to allow appeal
    to the Board.
    Such
    appeals
    are
    allowed
    by
    Section
    5(d)
    of
    the
    Act.
    The
    Board
    solicited
    comment
    on
    this
    Section,
    but
    received
    no response.
    PC#4
    suggests
    that
    the
    quantity
    limitations
    conflict
    with
    each
    other.
    The comment suggests that laboratories
    be allowed
    to
    store
    up
    to
    1000
    kg
    of
    non—acute hazardous waste for each process being evaluated for
    each
    wastestream, and
    that they be
    similarly limited
    to
    initiating studies
    on
    250
    kg per day for each process/wastestream.
    The language
    in the proposal
    appears to
    be consistent with the federal
    regulations,
    and
    the
    federal
    rules are sufficiently clear.
    USEPA
    has
    addressed the
    issues raised
    by the comments
    in the preamble to these
    rules.
    See 53 Fed. Reg. 27294, July 19,
    1988.
    To understand
    the rules one has to
    recognize that there may be more than
    one generator,
    shipper
    and
    laboratory involved
    in
    a given fact situation.
    The
    limitations for each have an independent logical
    basis,
    and there
    is
    no reason
    why the numbers need to
    be the
    same for each.
    Any one of these limitations
    may be the decisive factor
    in
    a given situation.
    Among other things,
    the laboratory limitations
    close possible loopholes
    which could
    be exploited to avoid
    the RCRA permit requirement.
    For example,
    suppose
    a laboratory offerred
    10 alternative processes
    to 100 generators.
    The
    generators could
    ship 1,000,000 kg for treatability studies.
    The laboratory’s
    1000 kg
    inventory cap makes certain that the amount
    in
    storage
    at any time
    is
    consistent
    with
    research,
    as
    opposed
    to~comercial storage
    or
    disposal.
    The
    250
    kg/day
    studies
    initiated
    rate
    prevents
    the
    laboratory from combining
    samples
    into
    commercial
    sized
    lots
    for
    treatment.
    Loosening
    these
    caps,
    as
    suggested by the comment, would
    allow a vast increase
    in
    the total
    inventory
    and
    rate of operation
    at
    the laboratory.
    This is precisely what USEPA intends
    to
    prevent.
    The Federal
    Register text has two probable incorrect references.
    In
    Section 261.4(e)(2)(vi)
    “paragraph
    (e)(v)(C)”
    should probably be
    “paragraph
    (e)(2)(v)(C)”.
    In Section 261.4(e)(3) “(e)(2)(ii)(vi)”
    should probably be
    “(e)(2)(ii)
    through (vi)”.
    Also,
    in Section 261.4(e)(3)(ii)
    “data” should
    probably be
    “date”.

    to
    the
    small

    exemptions
    in
    Section
    722.134, and
    to add a
    note
    defining
    “full
    regulation”
    Section
    721.133
    This
    Section
    was
    amended
    at
    53 Fed. Reg.
    13383,
    April
    22,
    1988,
    to
    correct the August
    6,
    1986 revisions
    to the chemical
    listings which appeared
    at
    51 Fed. Reg. 28298.
    As noted above, the Board
    has proposed and withdrawn
    these revisions two times, awaiting corrections
    to the USEPA rules.
    USEPA has noted
    a number of minor typographical errors
    in the proposal.
    (PC #3)
    The Board has generally corrected these
    to conform with USEPA’s
    comments,
    and the federal
    rules.
    Many of the federal
    names include
    a chemical
    formula.
    Some
    of
    these
    are
    salts
    of
    a
    metal
    and
    a
    molecular
    ion.
    The
    USEPA
    list
    uniformly
    encloses
    the
    anion
    in
    parentheses
    even
    when
    it
    is
    present
    in
    an
    equimolar
    ratio.
    For
    example,
    silver
    cyanide
    is
    written
    (in Appendix H)
    as Ag(CN)
    instead
    of
    AgCN.
    The parenthesis are not necessary
    in
    the formula
    for the
    salt, which
    is
    what USEPA probably
    intends.
    The unnecessary use of
    parentheses opens the
    door to
    an argument that the listing
    is
    intended to cover
    only the neutral
    complex Ag(CN)’~”,which
    is probably
    not the case.
    The difference between
    the
    salt and
    the complex
    is that, while
    in
    the complex
    a certain silver atom is
    associated with
    a
    single cyanide,
    in the
    salt
    the cation
    and
    anion are
    simply
    present
    in
    an equimolar
    ratio,
    either dissociated,
    in
    a crystal
    structure or
    as
    a complex.
    Section 721.App
    H
    This Section was amended
    at
    53 Fed. Reg. 13383,
    April
    22,
    1988, to
    correct the August
    6, 1986 revisions to the chemical
    listings which appeared
    at
    51 Fed. Reg. 28298.
    The Board
    has corrected
    a few probable errors
    in the USEPA text of this
    Appendix.
    The spelling
    of “2-acetylaminofluorene”
    has been corrected to agree
    with the entry for UOO5.
    The
    long form of the name for aldrin
    has an extra “10”.
    The long form of benzidine
    has
    a ~~41H
    which
    should
    be
    “4’”.
    The
    long form of 1,2—dichioroethylene has
    a mispelled “chioro-”.
    The long form of melphalan has
    an “aminol” which has been changed
    to
    “amino”
    to agree with the entry for U150.
    The long form of reserpine has
    a
    “smethyl” which
    as been changed
    to
    “methyl”
    to
    agree with the entry for U200.
    Section 722.110
    93—520

    —9-
    This Section was amended
    at
    53 Fed. Reg. 27164, July 19,
    1988,
    to correct
    references
    to the
    farmer exemption of Section 722.170.
    In addition, the Board
    has
    changed a reference to 40 CFR
    266 to the corresponding Part
    726, which has
    now been adopted
    as
    a Board rule.
    Section 722.151
    40 CFR 262.51 was amended
    at
    53 Fed. Reg. 27164, July 19,
    1988, to
    readopt
    the
    definitions
    for
    exports
    of
    hazardous
    waste,
    which
    USEPA
    inadvertently repealed through
    a number error.
    The Board
    corrected the main
    error
    in
    an earlier rulemaking.
    In this rulemaking, the Board has corrected a
    typographical
    error which occurred
    in the earlier rulemaking
    in one of the
    definitions.
    Section 724.101
    Section 724.1O1(f)(4) was amended
    at
    53 Fed. Reg.
    27164, July 19,
    1988,
    to correct
    a
    reference to the farmer exemption of Section
    722.170.
    Section 724.App.
    I
    The groundwater monitoring list was adopted
    in R87—39.
    In this Docket
    the Board
    has noted
    and corrected
    a few typographical errors.
    Section 725.101
    Section 725~.1O1(c)(B)was amended
    at
    53 Fed. Reg. 27164, July 19,
    1988,
    to correct
    a
    reference to the
    farmer exemption of Section 722.170.
    Part 728
    40 CFR 268 was amended
    at
    53 Fed.
    Reg.
    27164, July 19,
    1988,
    to correct
    references
    to the farmer exemption of Section 722.170.
    The Board
    believes
    that
    it noted
    and made
    all of the corrections
    in R87-39,
    and has not made any
    revisions in this Docket.
    PC
    1
    addresses the multi—state questions discussed
    in the R87—39
    Opinion.
    The Board
    invited additional
    public
    comment on
    these questions, but
    received no additional
    comment.
    As
    was’ discussed
    in R87-39,
    a definitive
    answer will
    probably require a position from USEPA headquarters.
    The Board
    will
    return
    to this issue when,
    and if, it arises again.
    This Opinion supports
    the Board’s Order of this same day.
    The Board will
    withhold filing the rules
    until
    December
    13,
    1988,
    to allow time for motions
    for reconsideration by the agencies involved
    in
    the authorization process.
