    IN THE MATTER OF:
    )
    R93—6
    UIC UPDATE,
    USEPA REGULATIONS
    )
    (Identical
    in Substance Rules)
    (6—1—92 THROUGH 12—31—92)
    )
    Proposal for Public Comment.
    PROPOSED OPINION AND ORDER OF THE BOARD
    (by J. Anderson):
    Pursuant to Sections 13(c)
    and 22.4(a)
    of the Environmental
    Protection Act
    (Act), the Board adopts amendments to the
    Underground Injection Control
    (UIC)
    regulations.
    Both Sections 13(c)
    and 22.4(a) provide for quick adoption
    of regulations which are “identical
    in substance” to federal
    regulations 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 UIC
    regulations are found at 40 CFR 144,
    146 and 148.
    This
    rulemaking updates UIC rules to correspond with federal
    amendments made in the period from July
    1 through December 31,
    1992.
    The USEPA actions during this period are as follows:

    PUBLIC COMMENTS
    The Board will receive public comment on this proposal for a
    period of 45 days following its publication
    in the Illinois
    Register.
    The Board will delay filing any adopted rules with the
    Secretary of State for 30 days after adoption, particularly to
    allow USEPA review.
    The complete text of the proposed amendments
    follows the discussions of this opinion.

    HISTORY OF RCRA,
    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
    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 USEPA 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.
    DISCUSSION
    The three federal actions that underlie this proceeding each
    have a distinct impact on the Illinois UIC regulations.
    This
    discussion focuses on each by subject matter and the Illinois
    Section impacted.
    Casing Inspection Logs-—Section 730.168(d) (4)
    At 57 Fed. Reg.
    46294
    (Oct.
    7,
    1992), USEPA amended 40 CFR
    146.68(d) (4), which corresponds with 35 Iii. Adm. Code
    730.168(d) (4)
    in the Illinois regulations.
    This section sets
    forth the requirements for owners or operators of Class
    I
    hazardous waste injection wells to test the mechanical integrity
    of their wells by running casing inspection logs.
    Formerly,
    USEPA required these tests every five years.
    The Director could
    waive the requirement if factors indicated that the results
    of
    running the logs would prove unreliable.
    As a result of
    a
    partial settlement of litigation,
    in NRDC v. EPA,
    No. 88—1657
    (D.C. Cir.), USEPA amended these requirements to generally a1lo~q
    the owner or operator to perform the tests as part of a routine
    well workover in which the injection string is pulled.
    The
    federal rule allows the Director of USEPA to waive the
    requirement based on the unreliability based on factors relating
    to the well.
    USEPA further added the condition that the Director
    could waive the requirement based on consideration of
    satisfactory results from a log run within the last five years.
    It also allows the Director to require owner or operator to run
    these logs every five years if there
    is reason to believe that
    the integrity of the long string casing of the well may be
    adversely affected by naturally—occurring or man—made events.
    The Board proposes amendments that follow the federal
    amendments very closely.
    We allow the Agency to require the
    testing, either during routine workovers or every five
    years,
    by
    ,
    ~
    ~

    3
    permit condition.
    The Agency’s determinations are based on
    consideration of the same factors as are enunciated in the
    federal rule.
    However,
    for greater clarity, the Board has
    subdivided this subsection into smaller subsections.
    Subsection
    (d) (1) provides for running the logs during routine workovers,
    and subsection
    (d) (2) provides for running them every five years.
    Subsection
    (d) (1)
    is further subdivided into two subsections so
    that the two bases for waiving the requirements stand out
    distinctly.
    A deviation from the federal language appears
    in subsection
    (d) (2).
    USEPA provided that the Director could require the five-
    year testing “if he has reason to believe” there were adverse
    effects on the well casing.
    The Board requires the Agency to
    “determine that it has reason to believe” there were effects.
    We
    made this change because Illinois administrative law requires the
    Agency to act on established standards.
    See Granite City
    Division of National Steel Co.
    v. PCB
    (Apr.
    15,
    1993),
    No.
    72850
    (slip op.).
    We believe that requiring the Agency to make a
    formal determination that there is reason to believe will satisfy
    this requirement.
    We do not feel free to delete the federal
    “reason to believe” language due to our experience in another
    federal identical-in-substance program.
    ~
    R91-3, SDWA Update,
    PC 12—PC
    15.
    If the Board were to delete this language, the
    Agency would only be able to require the five-year testing if it
    determines that the effect had indeed occurred.
    This would
    render the Illinois rules less stringent than the federal
    regulations.
    The Board
    invites public comment on its approach to Section
    730
    .
    168 Cd)
    (4)
    Relaxation of Prohibition of Land Disposal of Diluted Wastes——
    Section 738.101(d)
    USEPA amended 40 CFR 148.1(d)
    at 57 Fed. Reg.
    31963
    (July
    20,
    1992).
    This corresponds with 35 Ill. Adm.
    Code 738.101(d)
    in
    the Illinois UIC regulations.
    The effect of the federal
    amendment is to allow the injection of diluted wastes that no
    longer exhibit any characteristic of hazardous wastes into Class
    I hazardous waste injection wells.
    Formerly, USEPA amended this
    provision to allow the injection into Class I nonhazardous waste
    injection wells.
    The Board adopted the previous amendments in
    docket R92—13.
    In that docket we noted that the federal action
    was the subject of federal litigation in Chemical Waste
    Management,
    Inc.
    v. EPA
    (1992),
    976 F.2d
    2
    (D.C. Cir.).
    We noted
    that we are constrained to follow the language of the federal
    regulations notwithstanding the federal litigation until USEPA
    follows the court’s mandate and amends or repeals its rule.
    We
    added our usual Board Note indicating the federal litigation and
    noting that the rule may be unenforceable as a result.
    1
    L~~?~-O683

    In amending Section 738.101(d),
    the Board follows the
    federal amendments.
    We again highlight the earlier discussion of
    the federal litigation and the Board Note that mentions its
    possible effect on the rule.
    We feel constrained to follow the
    USEPA regulatory lead in this matter.
    In adapting the federal requirements to the Illinois
    regulations, the Board deviates from the federal structure.
    The
    federal rule is divided into two paragraphs,
    so that paragraph
    (d) (1) relates to Class
    I nonhazardous waste injection wells and
    paragraph
    (d) (2) relates to Class
    I hazardous waste injection
    wells.
    In R92-l3, the Board had already divided this provision
    to highlight the two elements:
    (1)
    Class
    I nonhazardous
    injection well and
    (2)
    exhibiting no hazardous characteristic.
    Since federal paragraph
    (d) (2) recites essentially the same
    thing,
    except that it relates only to Class
    I hazardous waste
    injection wells
    (and reverses the order of the two elements), we
    decided not to make this provision more convoluted by further
    subdivision.
    Subsection
    (d)
    combines both the hazardous and
    nonhazardous waste wells so that subsection
    (d) (1)
    recites Class
    I hazardous waste injection wells and Class
    I nonhazardous waste
    injection wells and subsection
    (d) (2)
    recites the no hazardous
    characteristic requirement.
    We added the “Class
    I” reference for
    clarity because this is the type of well defined at 35 Ill.
    Adm.
    Code 704.106(a)
    (corresponding to 40 CFR 144.6(a)).
    The Board invites public comment on our approach to Section
    738.101(d).
    Prohibitions on Inlection of Newly—Listed Wastes——Section 738.117
    USEPA added 40 CFR 148.17 at 57 Fed. Reg.
    37263
    (Aug.
    18,
    1992).
    This new provision is part of the broader rulemaking that
    imposed land disposal restrictions for newly listed wastes as
    part of the RCRA program.
    The
    RCRA
    aspects of these “land-bans”
    is the subject of RCPA update docket R93-4.
    The federal tJIC-only
    regulation
    is divided into three subsections..
    Subsection
    (a),
    listing 19 wastes,
    includes a prohibition and was effective
    November 9,
    1992.
    Subsection
    (b), which lists four additional
    wastes, includes a prohibition and will become effective on June
    30,
    1995.
    Subsection
    (c)
    lists the typical three conditions
    under which the prohibitions do not apply:
    (1) the wastes meet
    the 40 CFR 268, Subpart D treatment standards (corresponding to
    35 Ill. Adm. Code 728.Subpart D),
    (2) the wastes are the subject
    of an exemption from a prohibition (corresponding with an
    adjusted standard from a prohibition),
    or
    (3)
    if an extension of
    the effective date is granted pursuant to 40 CFR 148.4
    (corresponding to 35
    Ill. Adm. Code 738.104).
    In adopting the federal requirements to the Illinois UIC
    regulations, the Board has followed the federal rules nearly
    exactly.
    We reformatted subsections
    (a)
    and
    (b) to list the
    o~t~-QG3L~

    S
    wastes individually.
    We further kept with our routine practice
    and deleted the past effective date of subsection
    (a).
    The Board invites public comments on our approach to Section
    738
    117.

    History of RCRA and State Hazardous Waste Rules Adoption
    The Board has adopted and amended the Resource Conservation
    and Recovery Act
    (RCRA) hazardous waste rules
    in several dockets.
    Dockets R81-22 and R82-18 dockets dealt with the Phase I
    RCRA
    regulations.
    USEPA granted Illinois Phase
    I authorization on May
    17,
    1982,
    at 47 Fed. Reg.
    21043.
    The Board adopted RCRA Phase
    II
    regulations in Parts 703 and 724 in dockets R82-19 and R83—24.
    USEPA granted final authorization of the Illinois RCRA “base
    program” on January
    31,
    1986, at 51 Fed. Reg. 3778
    (January 30,
    1986).
    USEPA 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,

    5,
    1988, at 53 Fed.
    Reg.
    126
    (January 5,
    1988).
    USEPA authorized certain subsequent
    amendments and granted further partial HSWA authorizations

    effective April
    30,
    1990,

    and June 3,
    1991,
    at 56 Fed. Reg. 13595
    (April
    3,
    1991).
    USEPA
    codified its approvals of the Illinois program at 40 CFR 272.700
    and 272.701 on November 13,
    1989,
    at
    54
    Fed. Reg.

    In one proceeding filed,
    a petitioner seeks an adjusted
    standard from a UIC land disposal restriction, pursuant to the
    procedures oulined above with respect to the RCRA program
    (petitioner name in parentheses):
    P.92-S
    Presently pending.
    (Cabot Corp.)
    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
    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.

    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”,
    and
    “may”
    -
    “shall”
    is
    used
    when
    the
    subject
    of
    a
    sentence
    has to do something.
    “Must”
    is used when someone has to do something,
    but that someone
    is not the subject of the sentence.
    “Will” is used when the
    Board obliges itself to do something.
    “May”
    is used when choice
    of a provision is optional.
    “Or”
    is used rather than “and/or”,
    and denotes
    “one or both”.
    “Either”.
    .
    .
    “or” denotes “one but not
    both”.

    requirements
    shall
    at
    a
    minimum
    include:
    a)
    Monitoring
    of
    the
    injected
    wastes.
    1)
    The owner or operator shall develop and follow an
    approved written waste analysis plan that
    describes the procedures to be carried out to
    obtain
    a detailed chemical and physical analysis
    of a representative sample of the waste,
    including
    the quality assurance procedures used.
    At a
    minimum,
    the plan shall specify:
    A)
    The parameters for which the waste will be
    analyzed and the rationale for the selection
    of these parameters;
    B)
    The test methods that will be used to test
    for these parameters;
    and
    C)
    The sampling method that will be used to
    obtain a representative sample of the waste
    to be analyzed.
    2)
    The owner or operator shall repeat the analysis of
    the injected wastes as described in the waste
    analysis plan at frequencies specified in the
    waste analysis plan and when process or operating
    changes occur that may significantly alter the
    characteristics of the waste stream.
    3)
    The
    owner
    or
    operator
    shall
    conduct
    continuous
    or
    periodic
    monitoring
    of
    selected
    parameters
    as
    required
    by
    permit condition.
    4)
    The owner or operator shall assure that the plan
    remains accurate and the analyses remain
    representative.
    b)
    Hydrogeologic compatibility determination.
    The owner
    or operator shall submit information demonstrating that
    the wastestream and its anticipated reaction products
    will not alter the permeability, thickness or other
    relevant characteristics of the confining or injection
    zones such that they would no longer meet the
    requirements specified in Section 730.162.

    1)
    The owner or operator shall demonstrate that the
    waste
    stream
    will
    be
    compatible
    with
    the
    well
    materials
    with
    which
    the waste is expected to come
    into
    contact,
    and
    submit
    to
    the
    Agency a
    description
    of
    the
    methodology
    used
    to
    make
    that
    determination.
    Compatibility
    for the purposes of
    this
    requirement
    is
    established
    if contact with
    injected fluids will not cause the well materials
    to fail to satisfy any design requirement imposed
    under Section 730.165(b).
    2)
    The Agency shall require continuous corrosion
    monitoring
    of the construction materials used in
    the well for wells injecting corrosive waste, and
    may require such monitoring for other wastes,
    by:
    A)
    Placing coupons of the well construction
    materials
    in contact with the waste stream;
    or
    B)
    Routing
    the
    waste
    stream
    through
    a
    loop
    constructed with the material used in the
    well;
    or
    C)
    Using an alternative method approved by
    permit condition.
    3)
    If a corrosion monitoring program is required:
    A)
    The test must use materials identical to
    those used in the construction of the well,
    and such materials must be continuously
    exposed to the operating pressures and
    temperatures
    (measured at the well head)
    and
    flow rates of the injection operation; and
    B)
    The owner or operator shall monitor the
    materials for loss of mass,
    thickness,
    cracking, pitting and other signs of
    corrosion on a quarterly basis to ensure that
    the well components meet the minimum
    standards for material strength and
    performance set forth in Section 730.165(b).
    d)
    Periodic mechanical integrity testing.
    In fulfilling
    the requirements of Section 730.108, the owner or
    operator of
    a Class
    I hazardous waste injection well
    shall conduct the mechanical integrity testing as
    follows:
    1)
    The long string casing, injection tube,
    and
    annular seal must be tested by means of an
    4

    approved pressure test with a liquid or gas
    annually
    and
    whenever
    there
    has
    been
    a
    well
    workover;
    2)
    The
    bottom—hole
    cement
    must
    be
    tested by means of
    an
    approved
    radioactive
    tracer
    survey
    annually;
    3)
    An
    approved
    temperature,
    noise,
    or
    other
    approved
    log
    must
    be
    run
    at
    least once every five years to
    test
    for
    movement of fluid along the borehole.
    The Agency may require such tests whenever the
    well
    is
    worked
    over;
    4)

    The
    Agency
    may
    reciuire
    by
    permit that the
    owner or operator run a casing inspection log
    if
    it determines that it has reason to
    believe that the integrity of the long string
    casing of the well may be adversely affected
    by naturally—occurring or man—made events
    and
    5)
    Any
    other
    test
    specified
    by permit condition in
    accordance
    with
    the
    procedures
    in
    Section
    730.108(d)
    may also be used.
    e)
    Ambient Monitoring.
    1)
    Based on a site—specific assessment of the
    potential for fluid movement from the well or
    injection zone,
    and on the potential value of
    monitoring wells to detect such movement, the
    Agency shall require the owner or operator to
    develop a monitoring program.
    At a minimum, the
    Agency shall require monitoring of the pressure
    buildup in the injection zone annually,
    including
    at a minimum,
    a shut down of the well for a time

    18
    sufficient to conduct a valid observation of the
    pressure fall—off curve.
    2)
    When prescribing
    a monitoring system the Agency
    may also require:
    A)
    Continuous monitoring for pressure changes in
    the first aquifer overlying the confining
    zone.
    When such a well
    is installed, the
    owner or operator shall,
    on a quarterly
    basis,
    sample the aquifer and analyze for
    constituents specified by permit condition;
    B)
    The use of indirect, geophysical techniques
    to determine the position of the waste front,
    the water quality in a formation designated
    by permit condition,
    or to provide other
    site-specific data;
    C)
    Periodic monitoring of the groundwater
    quality
    in the first aquifer overlying the
    injection zone;
    D)
    Periodic monitoring of the ground water
    quality in the lowermost USDW;
    E)
    Any additional monitoring necessary to
    determine whether fluids are moving into or
    between USDW5; and
    F)
    The Agency may require seismicity monitoring
    when it has reason to believe that the
    injection activity may have the capacity to
    cause seismic disturbances.
