    OPINION AND ORDER OF THE BOARD (by C.A. Manning
    , K.M. Hennessey, and M.
    McFawn)
    :
    In 1995, the Illinois General Assembly adopted legislation repealing joint and several liability
    in actions involving environmental remediation and replaced it with proportionate share liability. See
    Pub. Act 89-443, eff. July 1, 1996. This new proportionate share scheme is contained in Section
    58.9 of the Environmental Protection Act (Act) (415 ILCS 5/58.9 (1996)). In the same piece of
    legislation, the Board was charged with adopting rules and procedures to determine proportionate
    share. These rules and procedures must be adopted before January 1, 1999. See Pub. Act 90-484,
    eff. August 17, 1997 (Amended 415 ILCS 5/58.9(d) (1996)). The Board today adopts those
    procedures for determining proportionate share.
    In this final opinion and order, the Board adopts the rules proposed at second notice with
    minor modification. The Board also discusses the procedural history of this rulemaking, including the
    Board’s major findings at first and second notice, and a summary of rules adopted today. Readers
    seeking a detailed discussion of the issues that the Board decided at first or second notice should
    consult the Board’s opinions and orders at first and second notice. See
    Proportionate Share Liability
    (35 Ill. Adm. Code 741)
    (September 3, 1998), R97-16;
    Proportionate Share Liability
    (December 3,
    1998), R97-16.
    PROCEDURAL HISTORY
    On December 5, 1996, the Board on its own motion opened a docket to solicit public
    comments and/or proposals to assist in the promulgation of rules and procedures implementing the
    proportionate share provisions of Section 58.9 of the Act. See
    Proportionate Share Liability
    (December 5, 1996), R97-16. On February 2, 1998, the Illinois Environmental Protection Agency
    (Agency) filed a rulemaking proposal with the Board to implement the provisions of Section 58.9.
    The Agency’s proposal was the result of a coordinated effort between the Agency, the Illinois
    Attorney General’s Office (AGO), and the Site Remediation Advisory Committee (SRAC).
    1
    On
    February 5, 1998, the Board accepted this matter for hearing. See
    Proportionate Share Liability
    (February 5, 1998), R97-16. Prior to adopting rules for first notice, the Board held four public
    1
     
    The SRAC was established by Section 58.11 of the Act, adopted as part of the Site Remediation
    Program legislation, to advise the Agency in developing regulatory proposals to implement Title XVII.
    See 415 ILCS 5/58.11 (1996). The SRAC consists of one member from each of the following
    organizations: the Illinois State Chamber of Commerce, the Illinois Manufacturers Association, the
    Chemical Industry Council of Illinois (CICI), the Consulting Engineers Council of Illinois, the Illinois
    Bankers Association, the Community Bankers Association of Illinois, and the National Solid Waste
    Management Association. See 415 ILCS 5/58.11(a) (1996).

    hearings.
    2
    Those hearings were held on May 4, 1998, in Springfield; May 12, 1998, in Chicago; and
    May 27 and June 10, 1998, in Springfield.
    At the May 4, 1998 hearing, Gary P. King, manager of the Division of Remediation
    Management within the Agency’s Bureau of Land, and John S. Sherrill, an Agency employee in the
    Remedial Project Management Section of the Division of Remediation Management within the
    Agency’s Bureau of Land, testified and responded to prefiled questions. At the May 12, 1998
    hearing, the Agency’s witnesses again testified, along with Matthew J. Dunn, Chief of the State-wide
    Environmental Enforcement/Asbestos Litigation Division of the AGO. At the May 27, 1998 hearing,
    the Agency’s witnesses again testified, along with several other witnesses: Sidney M. Marder,
    Executive Director of the Illinois Environmental Regulatory Group (IERG); David L. Rieser, a partner
    at Ross & Hardies, representing the Illinois Steel Group (ISG) and the CICI; David E. Howe, Senior
    Attorney at Caterpillar, Inc.; and Laurel O’Sullivan, Staff Attorney for Business and Professional
    People for the Public Interest (BPI). At the fourth hearing on June 10, 1998, Carey Rosemarin, an
    attorney with Jenner & Block, testified on behalf of Commonwealth Edison (Com Ed), and the
    Agency provided additional testimony in response to the other testimony presented at the hearings.
    At the close of the fourth hearing, the hearing officer established a deadline for interested
    persons to file public comments before the Board proceeded to first notice in this rulemaking.
    Fifteen public comments were received before the Board adopted rules for first notice.
    3
    On September 3, 1998, the Board proposed rules for first notice. See
    Proportionate Share
    Liability
    (September 3, 1998), R97-16. The proposal adopted was a modified version of the
    Agency’s proposal. Specifically, at first notice, the Board adopted rules: (1) providing for limited
    discovery before an action had been filed; (2) requiring that the Agency be notified of all actions
    seeking allocations of proportionate share; (3) providing for the mandatory disclosure and discovery
    of all documents pertaining to the release at a site; (4) listing allocation factors the Board could
    consider in making an allocation determination; (5) providing for reallocation in certain circumstances
    following a final determination; (6) governing how proportionate share could be raised as an
    affirmative defense, rather than adopting rules governing which party had the burden to prove
    proportionate share; and (7) governing voluntary allocation proceedings where all participants agree
    to allocate 100% of the performance or costs of a response.
    The Board also determined at first notice that the limitations contained in Section 58.1(a)(2)
    of the Act did not apply to Section 58.9, and thus the proportionate share rules. The Board reached
    this decision by looking primarily at the words in Section 58.9 “[n]otwithstanding any other provisions
    of this Act to the contrary.” The Board additionally concluded at first notice that Section 58.9 applied
    to private enforcement actions seeking cost recovery. In making this determination, the Board relied
    again on the language of Section 58.9. Finally, the Board also concluded at first notice that rather
    than assigning a particular party the burden to prove another’s proportionate share, the Board would
    make that determination based on all evidence presented by the parties. See
    Proportionate Share
    Liability
    (September 3, 1998), R97-16.
    The first-notice rules were published in the
    Illinois Register
    on September 18, 1998. See 22
    Ill. Reg. 16425-16440. They were also posted on the Board’s Web site and sent to the persons on
    the notice list. Upon publication in the
    Illinois Register
    , a 45-day public comment period began.
    2
    A prehearing conference was also held on October 28, 1997, in Springfield, Illinois.
    3
    For a complete list of all the public comments filed with the Board and all exhibits entered
    into the record in this proceeding, please refer to Attachments A and B, respectively.

    3
    During the first-notice period, the Board held two more publ
    ic hearings on October 19 and
    20, 1998, in Springfield. The purpose of those hearings was to allow the Board to receive testimony
    from interested persons on the merits of the Board’s first-notice proposal. At the October hearings,
    the following persons testified: Gary King of the Agency; Matthew Dunn and Elizabeth Wallace of
    the AGO; David Rieser on behalf of the SRAC; and Whitney Rosen on behalf of the IERG. To
    ensure that all public comments would be received and considered by the Board prior to second
    notice, the Board established November 9, 1998, as the deadline for receiving public comments.
    During this public comment period, the Board received six public comments.
    Based on the testimony at the October hearings and the public comments received following
    the adoption of the first-notice opinion and order, the Board made substantial revisions to the rules
    adopted at first notice. To receive public input on these changes before they were officially adopted
    for second notice, the Board adopted an opinion and order with proposed changes for second notice
    and solicited public comment on the changes by extending the first-notice comment period to
    November 23, 1998. The proposed second notice rules were sent to the persons on the notice list
    and were also posted on the Board’s Web site. See
    Proportionate Share Liability: 35 Ill. Adm. Code
    741 (November 12, 1998), R97-16. During the extended first-notice period, the Board received
    seven additional public comments.
    On December 3, 1998, the Board adopt
    ed proposed rules, with amendments based on the
    comments received after first notice, for second notice. See
    Proportionate Share Liability: 35 Ill.
    Adm. Code 741 (December 3, 1998), R97-16. The two major changes the Board made concerned
    the applicability of the proportionate share rules and the burden to prove a respondent’s
    proportionate share. Regarding applicability, the Board reconsidered its position, taken at first
    notice, on the applicability of the proportionate share rules. Upon reconsideration, the Board found,
    at second notice, that Section 58.1(a)(2) was ambiguous as to whether the limits in Section
    58.1(a)(2) applied to Section 58.9, and thus the proportionate share rules. Therefore, the Board
    looked to the legislative history of the Act and other aids to determine the legislative intent of Section
    58.1(a)(2). The Board found that the language of the Act as a whole, the purposes of the Act, and
    the legislative history of the Act, supported a finding that the limits of Section 58.1(a)(2) applied to
    Section 58.9 and thus the proportionate share rules. Based on this conclusion, the Board amended
    the applicability section of the proportionate share rules at second notice to reflect the limitations on
    the sites and persons subject to Title XVII in Section 58.1(a)(2). See
    Proportionate Share Liability
    (December 3, 1998), slip op. at 9-13.
    Further, based on the comments received after first notice, the Board was persuaded that
    Section 58.9 was a limitation on the remedy for an action seeking costs for a response or the
    performance of a response. Therefore, the Board deleted the sections contained in the rules at first
    notice concerning how proportionate share could be raised as an affirmative defense and replaced
    those sections with provisions on the burden of proof and final orders. Specifically, the Board
    determined that the burden to prove a respondent’s proportionate share should be placed on the
    complainant,
    i.e.
    , the complainant must prove that the respondent proximately caused or contributed
    to a release or substantial threat of a release and the degree to which the performance or costs of a
    response resulted from the respondent’s proximate causation of or contribution to the release or
    substantial threat of a release. The Board based this conclusion on the language of Section 58.9.
    The Board also found that the arguments that the burden should be on the respondent were without
    merit and that the burden to prove a respondent’s proportionate share should be on the complainant,
    just as the remainder of the Act places the burden of proving any other violation of the Act on the
    complainant. See
    Proportionate Share Liability
    (December 3, 1998), slip op. at 30-34.

    4
    Following the adoption of the rules for second notice, the Joint Committee on Administrative
    Rules (JCAR)
    4
    requested a few minor changes to the rules proposed at second notice. These
    changes are not substantive and do not merit discussion. With these minor modifications, JCAR
    considered the proposed rules at its December 15, 1998 meeting and voted an objection to Section
    741.105(f)(2) through (5) of the proposed rules. These subsections exclude from the proportionate
    share rules sites involving federal cleanups or federal regulatory programs that Illinois implements.
    These limitations are based on the limitations contained in Section 58.1(a)(2) of the Act, which is the
    applicability section for Title XVII. Specifically, JCAR stated that it objected to Section 741.105(f)(2)
    through (5) because “by creating exemptions from this Part, the rule contravenes Section 58.9(a)(1)
    of the Environmental Protection Act that broadly applies the concept of proportionate share liability to
    all remediation actions brought after the effective date of that Section.”
    The Board respectfully disagrees with JCAR’s conclusion. As the Board explained at second
    notice, Section 58.9(a)(1) is ambiguous as to whether the limitations contained in that section apply
    to Section 58.9 and thus the proportionate share rules. However, after considering the legislative
    history of Section 58.9 and the purposes of the Act, the Board concluded that the limitations in
    Section 58.1(a)(2), which exclude sites involving federal cleanups or federal regulatory programs
    that Illinois implements under Title XVII, applies to Section 58.9. Thus, the Board found at second
    notice that Section 58.9 or proportionate share liability applies only to the remaining universe of sites.
    See Proportionate Share Liability
    (December 3, 1998), slip op. at 9-13.
    The Board continues to b
    elieve that this interpretation is correct and is consistent both with
    the General Assembly’s intent and the language of the Act as a whole. The legislative debates on
    Title XVII certainly show that the General Assembly intended the various federal sites listed in
    Section 58.1(a)(2) to be excluded from the proportionate share scheme. For example, in response
    to a question about proportionate share liability, Representative Persico, Chairman of the House
    Energy and Environment Committee and the House sponsor of the underlying bill for Title XVII,
    stated:
    We exempt out of this particular Bill any federal or superfund site . . . . 89th Ill. Gen.
    Assem., House Proceedings, May 19, 1995, at 47.
    Similarly, Senator Mahar, Chairman of the Senate Environmental Committee and the Senate
    sponsor of House Bill 544 stated:
    [T]he legislation applies to all remedial activities, excluding specifically noted
    activities governed by federal law . . . . 89th Ill. Gen. Assem., Senate Proceedings,
    May 19, 1995, at 64.
    The language of the Act as a whole also makes it clear that the General Assembly intended
    Illinois to administer the federal solid waste, hazardous waste, and underground storage tank
    4
    JCAR is a legislative oversight committee that may “examine any proposed rule, amendment
    to a rule, and repeal of a rule to determine whether the proposed rule, amendment to a rule, or
    repeal of a rule is within the statutory authority upon which it is based; whether the rules,
    amendment to a rule, or repeal of a rule is in proper form; and whether the notice was given
    before its adoption, amendment, or repeal and was sufficient to give adequate notice of the
    purpose and effect of the rule, amendment, or repeal. In addition, [JCAR] may consider
    whether the agency has considered alternatives to the rule that are consistent with the stated
    objectives of both the applicable statutes and regulations and whether the rules is designed to
    minimize economic impact on small businesses.” 5 ILCS 100/5-110(a) (1996).

    5
    programs. See 415 ILCS 5/4, 20, 22.12, 57 (1996). The General Assembly did so because it
    wanted to avoid duplicative, overlapping, or conflicting State and federal programs. But, if
    proportionate share liability is applied to sites regulated under these programs, the United States
    Environmental Protection Agency (USEPA) has stated that it may withdraw Illinois’ authority to
    administer these programs. See Public Comments 11 and 23. Illinois also could lose federal
    funding to implement these programs. The Board’s interpretation of proportionate share liability
    therefore preserves Illinois’ authority to administer the federal programs. Finally, the Board’s
    interpretation is good public policy. Under the Board’s approach, proportionate share liability will be
    applied without jeopardizing Illinois’ regulatory programs.
    Because the Board sees no reason to modify the provisions on applicability in the rules, the
    Board today adopts the proposed rules without substantive change from second notice.
    5
    STATUTE IMPLEMENTED BY RULES
    Section 58.9 of the Act provides that no action may be brought:
    to require any person to conduct remedial action or to seek recovery of costs for
    remedial activity . . . beyond the remediation of releases of regulated substances that
    may be attributed to being proximately caused by such person’s act or omission or
    beyond such person’s proportionate degree of responsibility for costs of the remedial
    action of releases of regulated substances that were proximately caused or
    contributed to by 2 or more persons. See 415 ILCS 5/58.9(a)(1) (1996).
    Section 58.9 further exempts from performing remedial action any person who neither
    caused nor contributed to, in any material respect, the release of regulated substances. See 415
    ILCS 5/58.9(a)(2)(A) (1996). Section 58.9 also provides that if the State of Illinois seeks to require a
    person to conduct remedial activities, the Agency must provide notice to such person. The notice
    must include “the necessity to conduct remedial action pursuant to this Title and an opportunity for
    the person to perform the remedial action.” 415 ILCS 5/58.9(b) (1998). If the Agency has issued the
    statutorily-required notice, Section 58.9 provides that the Agency and person to whom such notice
    was directed may attempt to determine the costs of conducting the remedial action that are
    attributable to the releases to which such person or any other person caused or contributed. See
    415 ILCS 5/58.9(c) (1996).
    Nothing in Section 58.9, however, limits the authority of the Agency to provide notice under
    Section 4(q) of the Act or to undertake investigative, preventive, or corrective action under any other
    applicable provisions of the Act. Section 58.9 also does not apply to any cost recovery action
    brought by the State under Section 22.2 of the Act (415 ILCS 5/22.2 (1996)) to recover costs incurred
    by the State prior to July 1, 1996. See 415 ILCS 5/58.9(f) (1996).
    In addition to establishing proportionate share in environmental actions, Section 58.9 also
    directs the Board to adopt rules and procedures for determining proportionate share before January
    5
    Section 5-100(g) of the Illinois Administrative Procedure Act allows an agency to refuse to
    modify or withdraw a proposed rule to remedy an objection by JCAR. The agency must
    notify JCAR in writing of its refusal and submit a notice of refusal to the Secretary of State.
    The notice must be published in the next available issue of the
    Illinois Register
    . If JCAR
    decides to recommend legislative action in response to an agency refusal, then JCAR “shall
    have drafted and introduced into either house of the General Assembly appropriate legislation
    to implement the recommendations of the Joint Committee.” 5 ILCS 100/5-110(g) (1996).

    1, 1999. See Pub. Act 90-484, eff. August 17, 1997 (amended 415 ILCS 5/58.9 (1996)). The
    regulations adopted by the Board to implement Section 58.9 are to provide, at a minimum:
    criteria for the determination of apportioned responsibility based upon the degree to
    which a person directly caused or contributed to a release of regulated substances
    on, in, or under the site identified and addressed in the remedial action; procedures to
    establish how and when such persons may file a petition for determination of such
    apportionment; and any other standards or procedures which the Board may adopt
    pursuant to this Section. 415 ILCS 5/58.10(d) (1996).
    The rules and procedures adopted by the Board today fulfill the statutory mandates of
    Section 58.9.
    SUMMARY OF THE PROPORTIONATE SHARE RULES
    6
    The rules adopted today contain procedures and conditions under which the Board will
    allocate proportionate shares of the performance or cost of a response resulting from the release or
    substantial threat of a release of regulated substances or pesticides on, in, under, or from a site.
    See 415 ILCS 5/58.9(d) (1996).
    The rules apply to two types of proceedings. First, the rules apply to enforcement actions in
    which the State or a private party files a complaint with the Board that seeks to require another
    person to perform, or seeks to recover the costs of, a response. Second, the rules apply to
    proceedings in which two or more persons voluntarily seek to allocate 100% of the performance or
    cost of a response between themselves. In either type of proceeding, however, Part 741 does not
    apply to (a) actions to recover costs incurred by the State prior to July 1, 1996; (b) sites on the
    National Priorities List; (c) sites where a federal court order or a USEPA order requires an
    investigation or response; (d) the owner or operator of a site for which a permit has been issued or is
    required under federal or State solid or hazardous waste laws, or that is subject to closure or
    corrective action requirements under federal or State solid or hazardous waste laws; or (e) the owner
    or operator of an underground storage tank system subject to federal or State underground storage
    tank laws.
    The corresponding applicability provisions, as well as definitions an
    d other general
    information and procedures, are set forth in Subpart A. Subpart A also provides for discovery before
    an action is filed for the sole purpose of obtaining information necessary to identify persons who may
    have proximately caused or contributed to a release or threatened release. A party seeking to
    engage in such discovery must file a petition with the Board. The petitioner must support the petition
    with an affidavit stating the petitioner’s basis for belief that there has been a release or substantial
    threat of a release, that the respondent may have discoverable information, and that the petitioner
    could not obtain the information by any other reasonable means. A respondent may oppose a
    petition for prefiling discovery. Prefiling discovery may not be obtained against entities subject to the
    Freedom of Information Act (5 ILCS 140/1
    et seq.
    (1996)) and cannot require the production of
    privileged information.
    Subpart B sets forth the burden and standard of proof and elements of final order
    s allocating
    proportionate shares where a complaint has been filed by any person under the Act or the
    6
    This is a general summary and broadly describes the rules. Not all aspects of the proposed
    rules are addressed. For an in-depth analysis of the provisions in the rules and the issues
    raised regarding each section of the rules, please refer to the Board’s first- and second-notice
    opinions and orders.

    7
    Groundwater Protection Act (415 ILCS 55/1
    et seq.
    (1996)) to require another person to perform a
    response or to recover the costs of a response. To establish a respondent’s proportionate share, the
    complainant must prove that the respondent proximately caused or contributed to a release. The
    complainant must also provide evidence of the degree to which the response was the result of the
    respondent’s proximate causation of or contribution to a release of a regulated substance or
    pesticide. At the conclusion of the action, the Board will enter a final order determining whether the
    respondent proximately caused or contributed to a release. If so, the Board will also determine the
    respondent’s share of the response and order the respondent to perform or pay for its proportionate
    share of the response.
    In the second type of proceeding, the rules contained in Subpart C govern. Two or more
    persons who agree to accept 100% of liability to perform or pay for a response may initiate a
    voluntary allocation proceeding before the Board by filing a joint petition. These voluntary allocation
    procedures are available only if there is an Agency-approved Remedial Action Plan for the site or if
    there is a written agreement with the Agency regarding the performance of a response at the site
    following the issuance of a notice under Section 4(q) or Section 58.9(b) of the Act. At any time,
    participants may suspend a Subpart C proceeding for up to 120 days to engage in mediation. If the
    participants reach an agreement on allocation of proportionate shares, the participants can either file
    a motion to dismiss the allocation proceeding before the Board or file a stipulated settlement
    agreement with the Board. Absent an agreement, the Board will allocate liability among the
    participants based on the evidence presented at a hearing and enter an order directing the
    participants to perform the response or pay costs.
    Parties may
    obtain relief from final orders allocating proportionate shares, including
    reallocation, based on newly discovered evidence that existed at the time of hearing and could not
    have been discovered by due diligence. (Relief may also be obtained for fraud or a void order.)
    “Due diligence” in this context means diligence in performing studies common and appropriate to
    development of a remediation plan. A motion for relief must be filed within one year of entry of the
    order, unless the response begins within that year, in which case the time for filing a motion for relief
    is extended to three years. Either of these time periods may be extended by the Board for cause.
    CONCLUSION
    Based upon the record in this proceeding, the Board finds that adoption of the proposed
    rules is warranted. The Board also finds that these rules will not have an adverse economic
    impact on the people of the State of Illinois. See 415 ILCS 5/27(b) (1996).

    Allocation Factors
    In determining proportionate shares under this Part, the Board will consider any or all factors related

    the following:
    a)
    The volume of regulated substances or pesticides for which each person is
    responsible;

    changes in proportionate shares.
    d)
    A motion under subsection (a) of this Section must be filed with the Board within one
    year after entry of the order, except that when the response begins during this one-
    year period, a motion under subsection (a) of this Section must be filed with the
    Board within three years after entry of the order. Upon written motion, the Board may
    extend either of these periods for cause shown.

    SUBPART B: ALLOCATION OF PROPORTIONATE SHARES WHEN
    A COMPLAINT HAS BEEN FILED
    Section 741.200
    General
    This Subpart sets forth the procedures that apply when a complaint is filed with the Board that seeks,
    under the Act or the Groundwater Protection Act [415 ILCS 55], to require any person to perform a

    15
    response that results from a release or substantial threat of a release of regulated substances or
    pesticides, or to recover the costs of a response. This Subpart also sets forth the burden and
    standard of proof for such actions.
    Section 741.205
    Burden and Standard of Proof
    a)
    To establish a respondent’s proportionate share, the complainant must prove the
    following by a preponderance of the evidence:
    1)
    That the respondent proximately caused or contributed to a release or
    substantial threat of a release of regulated substances or pesticides on, in,
    under or from a site; and
    2)
    The degree to which the perfo
    rmance or costs of a response result from the
    respondent’s proximate causation of or contribution to the release or
    substantial threat of a release as established under subsection (a)(1) of this
    Section.
    b)
    Liability to perform or pay for a response that results from the release or substantial
    threat of a release of regulated substances or pesticides on, in, under or from a site
    is subject to all defenses allowed by law, including the defenses set forth in Section
    22.2(j) of the Act, and the limitations set forth in Section 58.9(a)(2) of the Act. The
    respondent raising a defense set forth in Section 22.2(j) or a limitation set forth in
    Section 58.9(a)(2) of the Act must prove the defense or limitation by a
    preponderance of the evidence.
    c)
    A complainant is not required to plead a specific alleged percentage of liability for the
    performance or costs of a response in a complaint that seeks to require a respondent
    to perform or pay for a response that results from a release or substantial threat of a
    release of regulated substances or pesticides.
    Section 741.210
    Final Orders
    a)
    Based on the evidence presented at hearing or in a stipulation, the Board will enter a
    final order that determines whether a respondent proximately caused or contributed
    to a release or substantial threat of a release.
     
    b)
    If the Board determines, under subsection (a) of this Section, that a respondent
    proximately caused or contributed to a release or substantial threat of a release, the
    Board will, in its final order, order respondent to perform or pay for a response. The
    Board will order the respondent to perform or pay for a response only to the degree
    to which a preponderance of the evidence shows that the performance or costs of the
    response result from the respondent’s proximate causation of or contribution to the
    release or substantial threat of a release. In making this decision, the Board will
    consider the allocation factors of Section 741.135 of this Part.
    c)
    If any party fails to comply with the Board’s order under this
    Section, any party may
    seek penalties under Section 42 of the Act. The Board may order a party that fails to
    comply with the Board’s order under this Section to pay penalties under Section 42 of
    the Act.

    specific shares of such liability, may initiate a voluntary allocation proceeding by filing
    a petition with the Board if:
    1)
    There is an Agency-approved Remedial Action Plan for the site under 35 Ill.
    Adm. Code 740; or
    2)

    been filed in any forum that addresses the same release or substantial threat of a
    release. If the Agency, the State, or any person files a complaint in any forum that
    involves the same release or substantial threat of a release, the Board may, upon

    17
    motion by any participant or at its discretion, stay the proceedings under this Subpart
    pending the outcome of the other proceeding. The State, the Agency or any party to
    the other proceeding also may appear specially to move the Board to stay the
    proceedings under this Subpart.

    c)
    If a hearing is requested as part of the joint proposal under subsection (a) of this
    Section, the hearing officer will issue an order to schedule and conduct the hearing
    and address any other matters as necessary. The order must require that, at least 30
    days before the date of hearing, each participant submit a pre-hearing memorandum
    setting forth the proportionate share that it accepts and the issues to be resolved at
    the hearing.
    Section 741.315
    Settlements
    Nothing in this Subpart prohibits the participants from at any time entering into a settlement for

    Agency.
    Section 741.320

    b)
    If the participants do not reach an agreement, the participants must report the lack of
    an agreement to the Board and file either:
    1)
    A joint motion to dismiss the Board action; or
     
    2)
    A joint motion to initiate or resume the Board allocation proceeding under
    Sections 741.310 and 741.315 of this Subpart.
    c)

    Section 741.330
    Board Review and Final Orders
    a)
    Based on the evidence pres
    ented at hearing or in a stipulation, the Board will enter a
    final order allocating a proportionate share to each participant.
    b)
    The Board’s final order will allocate 100 percent of the performance or costs of the
    response under the Remedial Action Plan or written agreement with the Agency. If
    the total of the agreed allocations under Section 741.310(a)(1) of this Subpart and the
    proportionate shares demonstrated during the hearing do not equal 100 percent of
    the performance or costs of the response, the Board’s order will allocate the
    remaining liability for performance or costs among all of the participants in the same
    ratio as the shares that have been agreed upon or demonstrated during the hearing.
    c)
    The Board’s final order will include an order to perform or pay for the response based
    on the proportionate shares determined during the proceeding.
    d)
    The Board may impose penalties under Section 42 of the Act if a participant fails to
    comply with a Board order under this Section.
    IT IS SO ORDERED.
    Section 41 of the Environmental Protection Act (415 ILCS 5/41 (1996)) provides for
    the appeal of final Board orders to the Illinois Appellate Court within 35 days of service of this
    order. Illinois Supreme Court Rule 335 establishes such filing requirements. See 172 Ill. 2d
    R. 335; see also 35 Ill. Adm. Code 101.246, Motions for Reconsideration.
    I, Dorothy M. Gunn, Clerk of the Illinois Pollution Control Board, hereby certify that
    the above opinion and order was adopted on the 17th
     
    day of December 1998 by a vote of 6-0.
    Dorothy M. Gunn, Clerk
    Illinois Pollution Control Board
