    Adopted Rule.
    Final Order.
    OPINION OF THE BOARD
    (by E.
    Dunham):
    Pursuant to Section 22.4(a)
    of the Environmental Protection
    Act
    (Act), the Board adopts amendments to the RCRA hazardous
    waste
    (RCRA)
    regulations.
    Section 22.4(a) provides for quick adoption of regulations
    that are “identical in substance” to federal regulations adopted
    by U.S. EPA to implement Sections 3001 through 3005 of the
    Resource Conservation and Recovery Act of 1976
    (RCRA,
    42 U.S.C.
    §S 6921—6925)
    and 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 federal RCRA
    Subtitle C regulations are found at 40 CFR 260 through 268, 270
    through 271,
    and, more recently,
    279.
    This opinion supports an order adopted on the same day.
    The
    Board proposed these amendments by an opinion and order adopted
    August 11,
    1994.
    Notices of proposed amendments appeared in the
    Illinois Register on September 2,
    1994,
    at 18 Ill. Reg.

    FEDERAL ACTIONS CONSIDERED IN THIS RULEMAKING
    This rulemaking updates the Illinois RCRA Subtitle C rules
    to correspond with federal amendments made in the period from
    January 1 through June 30,
    1994.
    The IJSEPA actions during this
    period are as follows:

    The June 7,
    1994 action did not result in federal regulatory
    amendments.
    Rather,
    it constituted a U.S. EPA determination that
    substantial confusion existed relating to the regulatory status
    of a waste, and it granted an extension of the time by which
    facilities managing the waste must file a Part A permit
    application.
    Although no Board action is required based on the
    June 7 federal action, we undertake an amendment discussed in
    greater detail below.
    PUBLIC COMMENTS
    The Board received public comment on this proposal for 45
    days following its publication On September 2,
    1994 in the

    3
    Illinois Reciister.
    During that period, the Board received the
    following comment:
    PC
    1 Secretary of State, Index Department, Administrative
    Code Division, by Connie Bradway (October 19,
    1994)
    By this public comment, the Secretary of State suggested a small
    number of Illinois Administrative Code format corrections.
    These
    are discussed below.
    In addition to the public comment, the Board recieved a
    series of documents from the Joint Committee on Administrative
    Rules
    (JCAR) entitled “Identical First Notice Line Numbered
    Version”.
    These include indications of corrections to format,
    grammar, punctuation,
    etc.
    Further, JCAR staff communicated with
    Board staff by telephone on these and additional questions and
    corrections.
    The corrections are discussed below.
    The Board will delay filing the adopted rules with the
    Secretary of State for 30 days after adoption, particularly to
    allow U.S. EPA review and comment.
    The complete text of the
    adopted amendments appears in a separate order adopted this day.
    During the pendency of the prior update docket,
    R94-7, the
    Board received a request from JCAR staff that the Board make
    certain minor corrections to the text of Part 739.
    We added
    those corrections to this docket.
    Those minor corrections
    involve Sections 739.152(b)(1)(B)
    and
    (b) (6) (H) (iii)
    and
    739.171(a).
    The nature of the corrections is readily apparent on
    the face of the order, so the Board will discuss them no further.
    HISTORY OF RCRA SUBTITLE C, UST and UIC ADOPTION
    AGENCY OR BOARD ACTION?
    EDITORIAL CONVENTIONS
    The Board appended three routine discussions at the end of
    this opinion.
    The first is
    a summary history of the Illinois
    RCRA Subtitle C and UIC programs.
    It lists all actions taken to
    adopt and maintain these programs since their inceptions.
    It
    includes a listing of all site-specific rulemaking and adjusted
    standards proceedings filed that relate to these programs.
    It
    also lists all U.S. EPA program authorizations issued to date.
    The second is a discussion of how the Board codifies requirements
    that call for state determinations,
    such as for exemptions,
    exceptions,
    etc.
    The third discussion relates to our use of
    language in the codification of identical—in—substance rules.
    We
    intend these as reference aids for interested persons in the
    regulated community.

    4
    DISCUSSION
    The federal actions that underlie this proceeding require
    amendment of the Illinois RCRA Subtitle C regulations.
    This
    discussion briefly focuses on each by subject matter, indicating
    the specific details of the actions taken by the Board where
    pertinent.
    Revised Reference for Letter of Credit Form—-Sections 704.240
    &
    724.251
    U.S. EPA revised references to the required form for using a
    letter of credit to provide financial assurance under the RCRA
    Subtitle C, underground injection control, and underground
    storage tank
    (RCRA Subtitle I)
    programs.
    U.S. EPA added that the
    form is copyrighted material.
    The amendments appeared at 59 Fed.
    Reg. 29958,
    on June 10,
    1994.
    U.S. EPA amended 40 CFR 144.70(d)
    (UIC)
    (corresponding with 35 Ill. Adm. Code 704.240), 264.151(d)
    and
    (k)
    (RCRA Subtitle C)
    (corresponding with 35 Ill.
    Adiu.
    Code
    724.251), and 280.99
    (UST).
    The Board followed the federal amendments without deviation.
    We included the UIC amendment in this docket for the sake of
    expedience,
    since the amendment is simple and straightforward and
    it is easier to deal with it together with the parallel RCRA
    Subtitle C amendment.
    Since Section 22.4(d) (3) expressly
    excludes financial assurance regulation by the Board in the UST
    area, no amendments were necessary to Part 731.
    The Board invited comment on our approach to codification of
    these federal amendments and received none.
    We construe silence
    as acceptance of the chosen approach.
    Decision Not to List Cholorophenolic Wood Surface Protection
    Wastes——Sections 720.111
    & 720.Appendix H
    U.S. EPA decided not to regulate certain wood surface
    protection wastes as listed hazardous wastes on January 4,
    1994,
    at 59 Fed. Reg. 458.
    U.S. EPA simultaneously announced its
    intent to reassess its determination if use of chlorophenolics
    for wood surface preservation resumes in the future.
    There is
    presently no active pesticide registration for chlorophenolics in
    the United States, and registration is required under the Federal
    Insecticide, Fungicide,
    and Rodenticide Act
    (FIFRA) for
    production and use of any pesticide in this country.
    Although it decided not to regulate the wastes as listed
    wastes, U.S. EPA amended “Test Methods for Evaluating Solid
    Waste, Physical/Chemical Methods”
    (SW—846) to add Method 4010,
    an
    immunoassay method for the presence of pentachlorophenol.
    Thus,
    U.S. EPA amended the reference to SW-846 at 40 CFR 260.11 (a)
    (corresponding with 35 Ill. Adm. Code 720.111(b))
    to include

    5
    Update hA.
    U.S. EPA corrected the reference
    ,
    at 59 Fed. Reg.
    28484,
    on June 2,
    1994, to indicate that Updates II and IIA to
    SW-846 are available from the Methods Information Communication
    Exchange
    (MICE)
    Service,
    rather than from the Government Printing
    Office.
    On January 4,
    1994, U.S. EPA also added four alkaline earth
    salts of chlorophenates to the list of hazardous constituents of
    40 CFR 261.Appendix VIII
    (corresponding with 35
    Ill.
    Adm. Code
    721.Appendix H).
    Added were potassium pentachiorophenate, sodium
    pentachlorophenate, and the sodium and potassium salts of
    2,3,4,6-Tetrachlorophenol.
    (U.S.
    EPA,
    in deciding to add these
    four compounds, decided not to similarly add two other related
    compounds:
    octachlorodibenzodioxin
    (OCDD) and octachlorodibenzo—
    furan (OCDF).)
    The Board has followed the federal amendments without
    deviation.
    The Board invited comment on our approach to
    codification of these federal amendments and received none.
    We
    construe silence as acceptance of the chosen approach.
    Response to City of Chicago remand/Extension of Permit
    A~~1jcationDeadline for Facilities Managing Ash from Waste—to—
    Energy Facilities——Section 721.104
    On June 7,
    1994,
    at 59 Fed. Reg. 29372, U.S. EPA formally
    responded to the decision in Environmental Defense Fund.
    Inc.
    v.
    City of Chicago,
    ——
    U.S.
    ——,
    114 5.
    Ct.
    1588,
    128 L. Ed. 2d 302
    (1994).
    In that case, the Court determined that section 3001(i)
    of RCRA
    (42 U.S.C.
    § 6921(1)) does not exempt ash from the
    incineration of non—hazardous municipal waste from regulation as
    a hazardous waste.
    Rather, the incinerator must use the
    appropriate methods to determine whether its waste exhibits a
    characteristic of hazardous waste.
    If the waste exhibits a
    characteristic, the generator must manage it as a hazardous
    waste.
    The history behind this is summarized in the Federal
    Register discussion of the extension.
    The Board repeats a few
    highlights here.
    In 1980,
    40 CFR 261.4(b) (1)
    (corresponding with
    35 Ill.
    Adin.
    Code 721.104(b) (1)) excluded municipal solid waste
    burned for energy recovery from regulation as hazardous waste if
    certain conditions are met.
    As part of the Hazardous and Solid
    Waste amendments of 1984
    (HSWA), Congress codified a
    clarification of the exclusion at section 3001(i), which U.S. EPA
    codified in 1985, announcing that it interpreted the exclusion to
    not include the ash from burning the wastes.
    Later,
    in the late
    80s, U.S. EPA took the position that the ash was exempted also.
    The Environmental Defense Fund filed two suits, one involving the
    City of Chicago, in the Northern District of Illinois, and
    another involving Wheelabrator Technologies,
    in the Southern
    District of New York, seeking enforcement of the 1985

    6
    interpretation.
    The Second Circuit ultimately ruled in favor of
    the exemption in Environmental Defense Fund,
    Inc.
    v. Wheelabrator
    Technologies,
    Inc.,
    931 F.2d 211
    (2d Cir.), cert denied, 112
    S.
    Ct.
    453
    (1991).
    The Seventh Circuit ultimately ruled that the
    ash was not included in the exemption in City of Chicago
    V.
    Environmental Defense Fund,
    Inc., 948 F.2d 345
    (7th Cir.
    1991).
    The Supreme Court affirmed the Seventh Circuit’s decision, and
    the City of Chicago appealed to the Supreme Court.
    The Supreme
    Court’s May 2,
    1994 affirmance of the Seventh Circuit’s decision
    resulted in the U.S. EPA action of June 7,
    1994.
    U.S. EPA determined that substantial confusion existed as to
    whether the ash was a hazardous waste,
    so, pursuant to 40 CFR
    270.10(e) (2),
    it is allowing persons managing the ash until
    December 7,
    1994 to file a Part A permit application.
    U.S. EPA
    will not require immediate RCRA
    § 3010 notification.
    This will
    allow those facilities that submit the application to continue
    managing the waste as they operate under interim status.
    However, the facilities must immediately comply with the
    appropriate hazardous waste management standards.
    From the
    perspective of the land disposal restrictions,
    U.S. EPA will
    consider the ash as a “newly—listed” waste.
    Land disposal
    restrictions will go into effect when U.S. EPA promulgates them--
    in about six months.
    The effect of the federal action varies from state to state,
    depending on the state’s authorization status and whether it has
    a codified ash exemption.
    Illinois does not have a codified ash
    exemption,
    so the Supreme Court’s decision went into effect in
    Illinois, as a matter of federal law, when handed down and no
    program revision is necessary to comply with the federal
    preemption requirements.
    Nevertheless, although this federal action does not
    technically require any Board action, the Court’s decision
    amounts to a change of law.
    Since the construction of the
    Illinois RCRA Subtitle C regulations depends so heavily on the
    federal interpretation of the statute and U.S. EPA rules, the
    decision is tantamount to the expiration of an exemption.
    Despite the fact that U.S. EPA has not amended its rules based on
    the remand, the Board undertook an amendment.
    To notify the
    regulated community of the change in law, the Board added an
    explanatory Board Note at the end of Section 721.104(b).
    This
    note explains that the Supreme Court has determined that the ash
    is not covered by the exclusion,
    and persons managing ash that
    meets the criteria for a characteristic waste, under Subpart C,
    must submit a Part A permit application by December 7,
    1994.
    The Board invited comment on its approach to the
    City
    of
    Chicago remand and U.S. EPA response and received none.
    We
    construe silence as acceptance of the chosen approach.

    Expansion of Treatabilitv Study Exclusion—-Section 721.104
    U.S. EPA expanded an existing exclusion from the definition
    of solid waste for varying amounts of hazardous waste used for
    treatability study.
    The amendments to 40 CFR 261.4 (e) (2),
    (e) (3),
    and
    (f) (3) through
    (f) (5)
    (corresponding with
    35 Ill.
    Adm. Code 721.104(e)(2),
    (e)(3), and (f)(3) through (f)(5))
    occurred at 59 Fed. Reg.
    8362, on February 18,
    1994.
    The amendments essentially changed the usage “soils, water
    or debris contaminated with hazardous waste” to “media
    contaminated with hazardous waste” and expanded the amounts of
    these materials that are exempted.
    Unaffected was the amount of
    hazardous waste itself that is exempted from regulation as
    hazardous waste.
    Thus,
    exempted for study are up to 10,000 kg
    (formerly 1,000 kg) of media contaminated with hazardous waste or
    up to 2,500 kg (formerly 250 kg) of media contaminated with acute
    hazardous waste.
    (The exemption remains for up to 1,000 kg of
    hazardous waste or up to
    1 kg of acute hazardous waste.)
    Also,
    the generator or accumulator may ship in a single shipment up to
    10,000 kg
    (formerly 1,000 kg) of media contaminated with
    hazardous waste or 2,500 kg
    (formerly 1 kg)
    of media contaminated
    with acute hazardous waste.
    (Unaffected was the shipment limit
    of 1,000 kg of hazardous waste or 1 kg of acute hazardous waste.)
    Finally,
    extensions of time are available for treatability
    studies.
    An extension of time is available for up to an
    additional 5,000 kg
    (formerly 500 kg)
    of media contaminated with
    hazardous waste or 2,500 kg
    (formerly 1 kg)
    of media contaminated
    with acute hazardous waste.
    (The extension limits of 500 kg and
    1 kg remain for hazardous waste and acute hazardous waste,
    respectively.)
    The amendments also allow up to an additional two
    years of study for bioremediation studies.
    Burlington Environmental Inc. filed a rulemaking proposal on
    July 1,
    1994, requesting that the Board adopt the expanded
    treatability studies exemption.
    The Board docketed that
    proceeding as R94-18.
    On July 18, Burlington requested that the
    Board adopt the expansion in R94—18 as an emergency amendment.
    The Board declined to adopt the amendments by emergency
    rulemaking on July 21,
    1994.
    Rather, the Board requested
    comments on whether the proposed amendments in this docket, R94—
    17 addressed Burlington’s concerns.
    The Board decided to
    expedite this matter to confer the benefits of the expanded
    exepmtion as soon as possible.
    The Board followed the federal amendments without
    significant deviation.
    We made minor clarifying revisions to the
    federal base text of Section 720.104(e)(3)(A).
    The Board invited
    comment on its approach to codification of these federal
    amendments and received none.
    We construe silence as acceptance
    of the chosen approach.

    8
    Corrected Listings for Beryllium Powder——Sections 721.133.
    721.Appendix H
    & 728.142
    U.S. EPA amended 40 CFR 261.33(e)
    (corresponding with 35
    Ill. Adm. Code 721.133 (e)),
    261, Appendix VIII (corresponding 35
    Ill. Adm. Code 721.Appendix H), and 268.42
    (corresponding 35
    Ill.
    Adm. Code 728.Table D) at 59 Fed.
    Reg. 31551
    (June 20,
    1994).
    These amendments change all the entries for beryllium dust,
    in
    the P015 listing for hazardous waste,
    in the hazardous
    constituents table, and in the land disposal restrictions, to
    “beryllium powder”.
    U.S. EPA designated this action a technical
    correction,
    of an April 22,
    1988 action,
    at 53 Fed. Reg.
    13383,
    so the correction was immediately effective without notice and
    comment.
    The Board adopted the federal technical correction without
    deviation.
    These amendments were not proposed in the August 11,
    1994 order because we accelerated these amendments to adopt the
    expanded exemption for treatability studies as soon as possible,
    as discussed above.
    We did not have the full listing of all
    federal actions that occurred during June,
    1994 at that time.
    Revised T/S/D Facility Reporting Codes——Sections 724.Appendix A
    &
    725.Ap~endixA
    U.S. EPA revised the codes used by hazardous waste
    treatment,
    storage, and disposal
    (T/S/D) facility reports in a
    set of technical amendments made on March 24,
    1994,
    at 59 Fed.
    Reg.
    13891.
    Amended were 40 CFR 264, Appendix
    I and 265,
    Appendix I
    (corresponding with 35 Ill. Adm. Code 724.Appendix A
    and 725.Appendix A).
    Both appendices,
    formerly only referenced
    in the Illinois
    RCRA
    Subtitle C regulations, are now formally
    incorporated by reference.
    The Board followed the federal amendments without deviation
    by updating the existing incorporations by reference.
    The Board
    invited comment on its approach to codification of these federal
    amendments and received none.
    We construe silence as acceptance
    of the chosen approach.
    Used Oil Mixed with Crude Oil or Natural Gas Liquids
    Exemptions——Sections 739.100, 739.110,

    739.144,
    739.146, 739.153

    On March 4,
    1994,
    at 59 Fed.
    Reg.
    10550, U.S. EPA amended
    the used oil regulations, primarily to revise a number of
    exemptions and exclusions.
    U.S. EPA amended 40 CFR 279.1
    (definitions of “petroleum refining facility” and “used oil
    transfer facility”)
    (corresponding with 35 Ill. Adm. Code
    739.100),
    279.10(b) (2) (iii)
    and
    (g)
    (corresponding with 35
    Ill.
    Adm. Code 739.110(b) (2) (C)
    and (g)), 279.20(b)(2)
    (corresponding
    with 35 Ill. Adm. Code 739.120(b) (2)),
    279.41(c)
    (corresponding

    9
    with 35 Ill. Adm. Code 739.141(c)), 279.46(a)(5) and (b)(5)
    (corresponding with 35 Ill.
    Adm. Code 739.146(a) (5)
    and
    (b) (5)),
    279.53(c)
    (corresponding with 35 Ill. Adm.
    Code 739.153(c)), and
    279.63(c)
    (corresponding with 35 Ill. Adm. Code 739.163(c)).
    First,
    the amendments to sections 279.1 and 279.10(g)
    (739.100 and 739.110(g))
    expand an exemption for certain used oil
    mixtures from regulation.
    Now exempted from regulation are the
    transportation and storage of mixtures of small amounts (less
    than one percent)
    of used oil and crude oil that are inserted
    into a crude oil pipeline or petroleum refining process at a
    point before catalytic cracking or distillation.
    Expressly
    regulated, however,
    is all management of the used oil up to the
    point of insertion into the pipeline or refining process.
    Second, the amendments to sections 279.1,
    279.10(b) (2)
    (iii),
    and 279.20(b) (2)
    and 279.41(c)
    (739.100,
    739.110(b) (2) (C), and
    739.120(b) (2)
    and 739.141(c)) add two exemptions from the used
    oil processor and re—refiner requirements.
    The first added
    exemption is that a transporter that filters used oil from oil-
    bearing transformers and turbines and returns it for its original
    use is not regulated as a processor or re—refiner.
    The second is
    that certain generator activities are not subject to the used oil
    processor requirements.
    These activities include filtering,
    cleaning,
    or otherwise reconditioning before reuse by the
    generator; separating used oil from wastewater generated on—site
    to make the wastewater acceptable for discharge or reuse; using
    oil mist collectors to remove oil from in—plant air for continued
    recirculation; draining or otherwise removing excess used oil
    from materials containing or otherwise contaminated; and
    filtering,
    separating, or otherwise reconditioning used oil
    before burning it in a space heater.
    Third, U.S. EPA amended section 279.46(a) (5)
    and (b)(5)
    (739.146(a) (5)
    and (b)(5))
    so that an intermediate rail
    transporter is no longer required to sign records for loads of
    used oil.
    Generally,
    a used oil transporter is required to sign
    for acceptance and delivery of used oil and maintain certain
    records.
    An intermediate rail transporter must still maintain
    the records, but needs no longer sign for acceptance or delivery.
    Finally, the federal amendments to sections
    279.10(b) (1)
    (ii),
    279.53(c),
    and 279.63(c)
    (739.110(b)(1)(B),
    739.153(c),
    and 739.163(c))
    remove the price for the third
    edition of “Test Methods for Evaluating Solid Waste, Physical!
    Chemical Methods”
    (SW-846)
    from the text of the rules.
    U.S. EPA
    noted that the price for that volume was $319.00, rather than the
    $110.00 formerly erroneously codified in the regulations.
    The Board followed the federal amendments without
    significant deviation.
    We made minor clarifying revisions to the
    federal base text of Sections 739.110(g) (4), 739.120(b),

    10
    739.141(c),
    and 739.146(a) (5) (A) and (b)(5)(A).
    The Board invited comment on its approach to codification of
    these federal amendments and received none.
    We construe silence
    as acceptance of the chosen approach.
    Corrected References to SPCC Regulations—-Sections 724.152.
    724.156, 725.152, 725.156
    & 739.152
    40 CFR 264.52(b),
    264.56(d) (2), 265.52(b),
    265.56(d) (2), and
    279.52(b)(2)(ii) and
    (b)(6)(iv)(B)
    (corresponding with 35 Ill.
    Adm. Code 724.52(b),
    724.56(d) (2), 725.52(b),
    725.56(d) (2), and
    739.52(b) (2) (B) and (b)(6)(D)(ii)) include references to the
    federal Spill Prevention Control and Countermeasures
    (SPCC) Plan
    regulations at 40 CFR 1510.
    Formerly codified at federal part
    1510, U.S. EPA redesignated those regulations as 40 CFR 300 on
    July 16,
    1982, at 47 Fed. Reg. 31202.
    U.S. EPA never updated the
    references to the SPCC regulations contained in the hazardous
    waste rules.
    In fact, when U.S. EPA added part 279, on September
    10,
    1992,
    it used the invalid references to the SPCC rules.
    Prompted by public inquiries regarding the intent of the
    regulations, the Board corrected all six references to the SPCC
    rules to correctly refer to 40 CFR 300.
    We undertook this action
    without regard to the fact that US. EPA has not moved to make
    this correction.
    We invited public comment on these corrections and received
    none.
    We construe silence as acceptance of the chosen approach.
    General Revisions
    The Board continued to change its method of referring to the
    United States Environmental Protection Agency in this present
    rulemaking.
    We began using this changed usage in update docket
    R93-16 and continued in R94-7.
    We now refer to “U.S.
    EPA”, which
    we believe is a more conventional and clearly understood in the
    context of the Illinois regulations than either “USEPA” or “EPA”.
    We further began to refer to the “U.S.
    EPA hazardous waste
    number” and “U.S.
    EPA document number” for similar clarity.
    This
    changed usage occurs only in the Sections opened in this
    proceeding, and we will continue this conversion in future
    rulemakings as additional Sections otherwise become open to
    amendment.
    The Board also continued its move toward presentation of
    equations and expressions in standard scientific notation.
    Thus,
    in Section 721.Appendix H, we used the appropriate chemical
    notation.
    For example, we replaced “H3A5O4” with
    “H3A5O4”, as
    formerly used for arsenic acid.
    We believe that any person
    sophisticated enough to understand the chemical equations will

    11
    more readily recognize them in the standard mathematical
    notation, as they appear in the federal original.
    In that
    Section we also corrected the chemical name in the entry for
    aldrin by adding a missing parentheses.
    The Board also
    substituted “or” for
    “/“
    in Section 720.104
    (b) (7) (L) and
    (b) (7) (Q) and “and” for
    “I”
    in Section 720.104(b) (7) and
    (b) (7) (N).
    The Board also used this opportunity to make a number of
    corrections to punctuation, grammar, and cross—reference format
    throughout the opened text.
    Where the cross—references within
    the text to other segments of the Illinois Administrative Code
    did not formerly comport with the standard format, the Board made
    the necessary changes.
    We also changed “who” to “that” and “he”
    to “it”, where the person to which the regulation referred was
    not necessarily a natural person,
    or to “he or she”, where a
    natural person was evident; changed “which” to “that” for
    restrictive relative clauses; substituted “shall” for “will”;
    capitalized the Section headings and corrected their format where
    necessary; and corrected punctuation within sentences.
    Public Comment—Based Corrections
    As mentioned above, the Board received several suggestions
    from
    JCAR
    staff and the Secretary of State for corrections to the
    text of the amendments as proposed.
    The Board tabulates the
    suggested corrections and our resulting actions as follows

    History of
    RCRA
    Subtitle C and State Hazardous Waste Rules
    Adoption
    The Board has adopted and amended the Resource Conservation
    and Recovery Act
    (RCRA)
    Subtitle C hazardous waste rules in
    several dockets.
    Dockets R81-22 and R82-18 dockets dealt with
    the Phase I
    RCRA
    Subtitle C regulations.
    U.S. EPA granted
    Illinois Phase
    I authorization on May 17,
    1982,
    at 47 Fed. Reg.
    21043.
    The Board adopted
    RCRA
    Subtitle C Phase II regulations in
    Parts 703 and 724 in dockets R82—19 and R83—24.
    U.S. EPA granted
    final authorization of the Illinois
    RCRA
    Subtitle C “base
    program” on January 31,
    1986, at 51 Fed. Reg. 3778
    (January 30,
    1986).
    U.S. EPA granted authorization to “Cluster
    I revisions”
    to the Illinois program and granted partial Hazardous and Solid
    Waste Amendments
    (HSWA)
    (Pub.
    L.
    98-616, Nov.
    8,
    1984)
    authorization effective March
    5,
    1988,
    at 53 Fed. Reg.
    126
    (January 5,
    1988).
    U.S. EPA authorized certain subsequent
    amendments and granted further partial HSWA authorizations
    effective April 30,
    1990,
    at 55 Fed. Reg. 7320 (March
    1,
    1990),
    and June 3,
    1991,
    at 56 Fed. Reg.
    13595
    (April
    3,
    1991); and
    August 14,
    1994, at 59 Fed. Reg.
    30525
    (June 14,
    1994).
    U. S. EPA
    codified its approvals of the Illinois program at 40 CFR 272.700
    and 272.701 on November 13,
    1989, at 54 Fed. Reg. 37649
    (Sep.
    12,
    1989), and on March 31,

    The Board added to the federal listings of hazardous waste
    by listing dioxins pursuant to Section 22.4(d) of the Act:

    This was repealed by R85-22, which included adoption of U.S.
    EPA’S dioxin listings.
    Section 22.4(d) was repealed by P.A. 85-
    1048, effective January

    History of UIC Rules Adoption
    The Board has adopted and amended Underground Injection
    Control
    (UIC)
    regulations in several dockets to correspond with
    the federal regulations.
    One such docket,
    R82-18, was a RCRA
    Subtitle C docket.
    U.S. EPA authorized the Illinois UIC program
    on March 3,
    1984,
    at 49 Fed. Reg.
    3991
    (Feb.
    1,
    1984); codified
    that approval as 40 CFR 147, Subpart 0, at 49 Fed. Reg.
    20197
    (May 11,
    1984); and amended the authorization at 53 Fed. Reg.

    AGENCY OR BOARD ACTION?
    Section 7.2(a)(5)
    of the Act requires the Board to specify
    which decisions USEPA will retain.
    In addition, the Board is to
    specify which State agency is to make decisions,
    based on the

    21
    general division of functions within the Act and other Illinois
    statutes.
    In situations in which the Board has determined that USEPA
    will retain decision-making authority, the Board has replaced
    “Regional Administrator” with USEPA, so as to avoid specifying
    which
    office
    within
    USEPA
    is
    to
    make
    a
    decision.
    In a few instances in identical in substance rules,
    decisions are not appropriate for Agency action pursuant to a
    permit application.
    Among the considerations in determining the
    general division of authority between the Agency and the Board
    are:
    1.
    Is the person making the decision applying a Board
    regulation,
    or taking action contrary to
    (“waiving”)
    a Board
    regulation?
    It generally takes some form of Board action to
    “waive” a Board regulation.
    2.
    Is there a clear standard for action such that the
    Board can give meaningful review to an Agency decision?
    3.
    Does the action result in exemption from the permit
    requirement itself?
    If so, Board action is generally
    required.
    4.
    Does
    the
    decision
    amount
    to
    “determining,
    defining
    or
    implementing
    environmental
    control
    standards”
    within
    the
    meaning of Section 5(b)
    of the Act.
    If so,
    it must be made
    by the Board.
    There
    are
    four
    common
    classes
    of
    Board
    decision:
    variance,
    adjusted
    standard,
    site
    specific
    rulemaking,
    and
    enforcement.
    The
    first
    three
    are
    methods
    by
    which
    a
    regulation
    can
    be
    temporarily
    postponed
    (variance)
    or
    adjusted
    to
    meet
    specific
    situations
    (adjusted
    standard
    or
    site
    specific
    rulemaking).
    Note
    that
    there
    often
    are
    differences
    in
    the
    nomenclature
    for
    these
    decisions
    between
    the
    USEPA
    and
    Board
    regulations.
    EDITORIAL
    CONVENTIONS
    As
    a
    final
    note,
    the
    federal
    rules
    have
    been
    edited
    to
    establish a uniform usage throughout the Board’s regulations.
    For
    example,
    with
    respect
    to
    “shall”,
    “will”,
