    OPINION AND ORDER OF THE BOARD (by C.A. Manning, K.M. Hennessey, and M.
    McFawn):
    On December 21, 1995, Governor Jim Edgar signed into law House Bill 901 as Public Act 89-443,
    effective July 1, 1996. This amendatory legislation added Section 58.9 to Title XVII of the Environmental
    Protection Act (Act). This new section repealed joint and several liability in environmental actions and replaced it
    with proportionate share liability. Today, the Board sends out for public comment the rules as the Board
    anticipates they will appear at second notice. The Board has made several changes to the rules since first notice
    and is taking this action today in order to receive comment on the changes before proceeding to second notice
    under the Administrative Procedure Act (5 ILCS 100/1-1
    et seq.
    (1996)). By sending these rules out for public
    comment today, the Board will be able to make any changes necessitated by any comments before proceeding to
    second notice. In the sections that follow, the Board will provide some background for this rulemaking and a brief
    summary of the more substantive changes made to the proposed rules after first-notice publication.
    BACKGROUND
    Before adopting a proposal for first-notice publication in this rulemaking, the Board held four public
    hearings in this matter.
    1
    Those hearings were held on May 4, 1998, in Springfield, May 12, 1998, in Chicago, and
    May 27 and June 10, 1998, in Springfield. On September 3, 1998, the Board adopted procedures for determining
    proportionate share for first-notice publication. See Proportionate Share Liability (35 Ill. Adm. Code 741)
    (September 3, 1998), R97-16. Following the adoption of the proposal for first notice, the Board held two more
    public hearings in Springfield on October 19 and 20, 1998. 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. Subsequent to
    those hearings, the Board received the following public comments:
    2
    PC 17: First-notice Comments of the Illinois Environmental Protection Agency (Agency) (11/4/98).
    PC 18: First-notice Comments of the United States Environmental Protection Agency (11/4/98).
    PC 19: First-notice Comments of Karaganis & White (11/4/98).
    1
    References to the Agency’s proposal will be cited to as “Prop. at __.” References to the
    Agency’s Statement of Reasons will be cited to as “Stat. at __.” References to the hearing
    transcripts will be cited to by volume as “Tr._ at __.” References to exhibits will be cited to
    by number as “Exh. __.” Finally, references to public comments will be cited to by number
    as “PC _.”
    2
    The Board has received in total 21 public comments in this proceedings. In this opinion,
    however, the Board only cites those comments received after the October hearings. For a list
    of the other comments received, please refer to the Board’s first-notice opinion and order.

    2
    PC 20: First-notice Comments of the Illinois Attorney General’s Office (AGO) (11/4/98).
    PC 21: First-notice Comments of the City of Chicago (11/4/98).
    Based on the comments at the October hearings and the public comments received following the adoption
    of the first-notice opinion and order, the Board has made several changes to the rules since first notice. In order to
    receive public input on these changes before they are adopted for second notice, the Board is extending the first-
    notice comment period and is sending the proposed rules out for public comment and review prior to adopting
    them for second notice. Given the statutory timeframe governing the Board in this proceeding, the public comment
    must unfortunately be limited. Despite the shortness of time, the Board believes that it is the better course of
    action to have a limited pre-second notice review than none at all. Accordingly, public comments must be received
    by the Clerk of the Board no later than 4:30 p.m. on November 23, 1998, to ensure that the comments will be
    considered by the Board in its deliberations as to how the regulations should read at second notice. The “mailbox
    rule” as set forth in 35 Ill. Adm. Code 101.102(d) does not apply to this filing. Telefax filings will be allowed.
    See 35 Ill. Adm. Code 101.102(c). The Board expects to move to second notice at the Board’s December 3, 1998
    meeting.
    Anyone may file a public comment. If a person filing a public comment is on the service list, however,
    that person must also simultaneously send a copy of the public comment to all persons on the service list. As the
    service list may be updated from time to time, you should contact the hearing officer or the Clerk’s Office to
    confirm that you have a copy of the current service list. All comments should reference the docket number in this
    proceeding, R97-16, as well as the name, address, and affiliation, if any, of the commentor.
    A copy of the Board’s opinion and order adopted today, as well as the Board’s first-notice opinion and
    order, is available from the Clerk’s Office and the hearing officer. The Board’s opinions and orders are also
    available from the Board’s web site at http://www.ipcb.state.il.us. Transcripts from all the hearings in this matter
    are also available from the Clerk’s Office and from the Board’s web site.
    As the Board and other participants have noted, proportionate share is a new concept, and it therefore
    raises some difficult and complex issues. As a result, throughout the course of this proceeding, approximately
    1,350 pages of testimony, questions, public comments, responses, and exhibits have been gathered. In adopting
    the proposed rules for pre-second notice publication, the Board has reviewed and considered all matters of record,
    including the testimony, exhibits, and public comments submitted by the Agency and other participants in this
    rulemaking. The Board commends the Agency, the AGO, the Site Remediation Advisory Committee (SRAC), and
    all others who participated in this proceeding. The time and thought that the participants devoted to this
    rulemaking gave the Board a well-developed record upon which to resolve those issues. The Board looks forward
    to the continued participation of these and other participants in this rulemaking.
    In the section that follows, the Board summarizes the more substantive changes that were made to the
    first-notice proposal. Those wanting to review all the changes should consult the order portion of this document
    which shows all the changes made since the first notice proposal. The Board will provide a more detailed
    explanation of the changes when the Board adopts the proposal for second notice. However, in order to allow for a
    pre-second notice review by the participants, the Board could not provide the detailed explanation at this time.
    Again, the proposed rules are how the Board anticipates they will read at second notice. Based on any comments
    received on these draft rules, the Board may incorporate suggested changes into the rules before they are officially
    adopted for second notice. Readers seeking an overview of the first-notice proposal should consult the first-notice
    opinion and order. See Proportionate Share Liability (35 Ill. Adm. Code 741) (September 3, 1998), R97-16.
    SUMMARY
    Subpart A

    3
    Section 741.105 Applicability
    At first notice, the Board declined to accept that part of the Agency’s proposal that excluded certain sites
    or persons from Part 741 based on the limits contained in Section 58.1(a)(2) of Title XVII of the Act. Rather, as
    the Board interpreted Section 58.9, it was not limited by the provisions of Section 58.1(a)(2). The Board’s
    interpretation rested primarily on the first phrase of Section 58.9, “[n]otwithstanding any other provisions of this
    Act to the contrary.” The Board found that the “notwithstanding” language was clear and that Section 58.9 should
    therefore apply to all actions brought pursuant to the Act or the Groundwater Protection Act that seek a response
    or response costs.
    The Agency, the AGO, and the SRAC continue to maintain that Section 58.1(a)(2) limits the applicability
    of Section 58.9. Based on the testimony and comments provided since first notice, the Board is persuaded that
    Section 58.1(a)(2) itself is ambiguous on the question of whether it limits Section 58.9. This ambiguity requires
    the Board to consider the legislative history of Title XVII, which favors the position espoused by the Agency, the
    AGO, and SRAC. In addition, the Board has considered the Act as a whole, including such provisions as Section
    20(a)(8), in which the General Assembly found that “it is in the interest of the People of the State of Illinois to
    authorize such a hazardous waste management program and secure federal approval thereof, and thereby to avoid
    the existence of duplicative, overlapping or conflicting state and federal programs.” See 415 ILCS 5/20(a)(8)
    (1996); see also Tr.5 at 94-95. Accordingly, in this draft proposal, the Board finds that the limitations in Section
    58.1(a)(2) do apply to Section 58.9, thereby limiting the applicability of the Section 58.9.
    3
    Section 741.105(f)
    reflects this change.
    The Board has also made some other organizational and language changes in Section 741.105.
    Specifically, the Board has added a provision that the Board’s procedures rules apply, unless there is a conflict
    between the procedural rules and the rules contained in Part 741. See Section 741.105(b). The Board has also
    included a provision which sets forth the proceedings which Part 741 applies to. See Section 741.105(a)(1), (2).
    The language is taken substantially from the statutory language of Section 58.9(a)(1) of the Act.
    In the Board’s first-notice opinion and order, the Board concluded that the regulations for determining
    proportionate share should apply to private enforcement actions that seek to recover costs. The Agency, the AGO,
    and the SRAC continue to raise concerns regarding this issue. The Board continues to believe that the statutory
    language covers private enforcement actions seeking cost recovery, and we therefore continue to include them in
    these rules. See Section 741.105(a)(1). The Board nonetheless recognizes that the inclusion of private
    enforcement actions seeking cost recovery presents complicated issues that cannot be fully examined in this
    rulemaking. At hearing, the Board raised a potential solution to these issues by linking private cost recovery
    actions to the Site Remediation Program. See Tr.5 at 30. The Board remains interested in attempting to resolve
    procedural difficulties inherent in private costs recovery actions, and if any participant would like this issue to be
    explored more fully in a separate docket, the Board would welcome comments on the merits of opening a separate
    docket.
    Section 741.110 Definitions
    Because the term proportionate share is used throughout the rules, the Board has included in this draft
    proposal a definition of “proportionate share.” The language of the definition is based on the statutory language of
    Section 58.9. “Proportionate share,” as proposed, “means a person’s liability to perform or pay for a response that
    results from a release or substantial threat of a release of regulated substances or pesticides on, in or under a site,
    based on the degree to which the performance or costs of a response result from the person’s proximate causation
    of or contribution to the release or substantial threat of a release.”

    For those readers who would like a more in-depth analysis of the issues regarding
    applicability, please consult the Board’s first-notice opinion and order.

    4
    Section 741.115 Discovery Before an Action is Filed
    The Board has made several organizational changes to Section 741.115. The Board has also included
    some additional limitations on a petition brought under Section 741.115 to identify persons who may have
    proximately caused or contributed to a release or substantial threat of a release. These changes include: (1) the
    standard that the Board will use in determining whether to grant such a petition (see Section 741.115 (g)); (2) that
    the Board’s order will automatically expire within 60 days after its issuance (see Section 741.115(h)); (3) that the
    petitioner must bear the reasonable expenses of providing the discovery (see Section 741.115(i)); and (4) that a
    petition under Section 741.115 may not be brought to obtain information from an agency subject to the Freedom of
    Information Act (5 ILCS 140 (1996)) or for information privileged under 35 Ill. Adm. Code 101 and 103 (see
    Section 741.115(k)). These changes were made in response to comments from several of the participants. See
    Exh. 19.
    Section 741.120 Section 58.9(b) Notice
    In the Board’s first-notice proposal, Section 741.120 addressed Section 58.9(b) of the Act. Specifically,
    Section 741.120 in the Board’s first-notice proposal related to the requirement of Section 58.9(b) of the Act that
    the Agency provide notice to a person of the need to perform a cleanup and an opportunity for the person to
    perform the cleanup. Section 741.120 also had procedures for the Agency to meet with the recipient of the notice.
    Because the proposed rules address only Board procedures, the Board has deleted most of Section
    741.120 as it was contained in the Board’s first-notice proposal. The Board has retained that portion of the rule,
    however, that repeats the requirements as set forth in the statute and continues to require that notice be provided
    whenever the Agency seeks to require a person to perform a response. This provision will put the public on notice
    of the statutory requirements. Of course, the Agency may adopt whatever procedures it deems necessary to
    implement its responsibilities under Section 58.9.
    Section 741.125 Notice to Agency
    Concerns were raised regarding whether the Agency should receive notice of all actions seeking an
    allocation of proportionate share. Based on the comments received, the Board has retained the provision requiring
    that any person seeking an allocation of proportionate share serve a copy of the complaint or Subpart C petition on
    the Agency. After receiving the notice, the Agency may choose, but is not required, to participate in the
    proceeding. The Board has made clear, however, that if the Agency wishes to participate in the proceeding, it
    would need to file a petition to intervene under the Board’s procedural rules. Once the petition was granted, the
    Agency would then have all the rights of an original party. The provisions on intervention were added to clarify
    the Agency’s role in a proportionate share proceeding.
    Section 741.130 Discovery After an Action is Filed
    The Board has included language, suggested by the Agency, that documents must be compiled and made
    available for review that pertain to not only the release or threatened release, but also to a person’s proportionate
    share. The Board has also included a provision that would protect from disclosure under this section privileged
    documents.
    Section 741.135 Allocation Factors
    In the Board’s first-notice proposal, Section 741.135 contained provisions regarding the conduct of
    hearings. However, after further reflection, the Board believes that hearings where a response or response costs
    are sought will proceed like any other enforcement action. Therefore, the Board has included a provision in the
    applicability section that provides that the Board’s procedural rules apply unless otherwise noted. As a result, the

    5
    Board has determined that a specific section on the conduct of hearings is unnecessary and has deleted it from the
    proposal.
    In the proposal adopted today, Section 741.135 now deals with allocation factors. The Board has made
    several changes to this section based on the statutory language of Section 58.9.
    Subpart B
    Sections 741.205 and 741.210
    In the Board’s first-notice proposal, the Board had various sections in Subpart B dealing with the
    initiation of an allocation determination, proportionate share as a defense, necessary parties, pleading, proof of
    liability, and settlements. As the Board viewed the procedure at that time, there would be a proceeding to
    determine liability under the Act. Then, once liability under the Act had been established, a separate non-
    adversarial proceeding would commence to allocate shares of the response or response costs. In order to ensure
    that all the information regarding a person’s proportionate share was disclosed, the Board included procedures
    regarding necessary parties, how to raise proportionate share as an affirmative defense, and how to plead
    proportionate share.
    Following the first-notice proposal, the Board received several comments and heard testimony
    questioning the procedures set forth in the Board’s first-notice proposal. Based upon those comments, the Board
    has made several changes to Subpart B. Besides a general introductory provision, the rules that the Board
    proposes today for Subpart B only contain provisions on the burden and standard of proof and final orders. All
    other provisions contained in Subpart B at first notice have been removed.
    With Subpart B, the Board must once again look to the statutory language and meaning of Section 58.9 of
    the Act. In essence, Section 58.9 places a limit on the remedies that can be obtained from a person in an action
    seeking response costs or to require a response. With this in mind, the Board views a proceeding under Section
    58.9 to be similar to an enforcement action, where the complainant has the burden of proving the violation of the
    Act and, to some extent, the remedy it seeks. While a complainant does not have to plead a specific percentage of
    liability for the performance or costs of a response, it does have to put forth sufficient evidence for the Board to
    determine the degree to which the performance or costs of a response resulted from the respondent’s proximate
    cause of or contribution to a release or substantial threat of a release. Accordingly, the Board has included in
    Section 741.205 that the burden is on the complainant to prove by a preponderance of the evidence 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 cause of or contribution to the
    release or substantial threat of a release. The board has also included a provision in the rules that any defense
    raised in the action must be proved, as usual, by the person asserting the defense.
    Subpart C
    Section 741.300 General
    In the Board’s first-notice proposal, a Subpart C proceeding was limited to persons who sought to
    allocate among themselves the entire costs of the response. The Board has made changes to Subpart C to make
    clear that the participants can seek to allocate among themselves 100 percent of the performance or costs of a
    response, whether or not the response has been performed.
    Section 741.320 Mediation
    At first notice, the Board proposed a voluntary allocation proceeding under Subpart C where the
    participants could choose to engage in mediation or to proceed with the Board’s allocation procedure. The Board

    6
    requested comment on whether the mediation provisions would be useful. Because the Board received no
    comment on the propriety of these provisions, the Board is hesitant to proceed with the procedural rules governing
    the mediation proceeding at this time without comment from the participants. Accordingly, the Board has deleted
    many of the procedural provisions concerning mediation at this time. The Board understands that the participants
    have placed more of the focus on other subparts. However, the Board would appreciate some comment on whether
    the mediation provisions should be retained or changed at second notice. If participants believe that mediation
    would be useful, the Board would also appreciate comment on whether more specific mediation provisions should
    be developed through a separate rulemaking.
    Other Matters
    The Board asked at the final hearing in this rulemaking what the various participants’ positions were on
    the Board missing its statutory deadline in order to allow for further discussion of the rules. Tr.5 at 176-178.
    Some of the participants supported the approach in order to examine the changes before the rules were adopted for
    second notice. See PC 19; PC 20. However, because the Board intends to meet its statutory deadline, the Board
    has, at this point, provided for a short time period for review prior to adopting the rules for second notice.
    ORDER
    The Board adopts the proposed rules set forth below for public comment. Additions from first notice are
    underlined. Deletions from first notice are denoted by strike-through marks.
