    ORDER OF THE BOARD (by M. McFawn):
    This case is before the Board on the “Motion to Strike Respondent’s Affirmative
    Defenses” filed by the Attorney General on May 23, 1997. On April 7, 1997, the Attorney
    General, on behalf of the people of the State of Illinois, filed a complaint against respondent
    Midwest Grain Products of Illinois, Inc. (Midwest Grain), alleging violations of air pollution
    provisions of the Environmental Protection Act, 415 ILCS 5/1
    et seq.
    (1996) (Act), as well as
    the federal Clean Air Act and Prevention of Significant Deterioration (PSD) regulations.
    Midwest Grain filed its “Answer” on May 7, 1997, interposing four affirmative defenses to
    the Attorney General’s claims. The Attorney General asks that each affirmative defense be
    stricken as substantially insufficient at law. The Board denies the Attorney General’s motion
    with respect to Midwest Grain’s first and third affirmative defenses and grants the Attorney
    General’s motion with respect to Midwest Grain’s second and fourth affirmative defenses.
    ALLEGATIONS
    1
    At all times relevant to this case, Midwest Grain has operated a facility in Pekin,
    Illinois, that produces ethyl alcohol, anhydrous fuel alcohol, wheat gluten and distiller’s feed.
    In 1993, Midwest Grain applied to the Illinois Environmental Protection Agency (Agency) for
    a construction permit in order to replace two existing feed dryers with new dryers (dryers 651
    and 661). In May of 1993, the Agency issued construction permit number 93020061 to
    Midwest Grain. In December of 1993, the Agency issued construction permit number
    93080045 to Midwest Grain. Permit 93020061 limits particulate matter emissions from dryer
    651 to 1.1 pounds per hour. Permit 93080045 limits total particulate matter emissions from
    both dryers to 3.2 pounds per hour. Both permits require secondary scrubbers after both feed
    dryers.
    1
    The information set forth here has been taken from the allegations in the Attorney General’s
    complaint. Some of the allegations have been denied by Midwest Grain. The Board does not,
    by setting forth this narrative, make any finding as to the truth of any allegation.

    2
    After receiving the permits, Midwest Grain commenced construction of the new dryers.
    Stack testing conducted on one of the dryers in May of 1995 indicated actual emissions of 17.1
    pounds per hour. On September 21, 1995, the Agency inspected Midwest Grain’s facility.
    The Agency inspector determined that Midwest Grain operated the dryers unpermitted,
    operated the dryers in excess of the particulate matter emission standards in the construction
    permits, operated the dryers without secondary scrubbers, and constructed a major
    modification without applying for and obtaining a PSD construction permit.
    Application of the federal PSD regulations is triggered when a “major source”
    undergoes a modification resulting in a “significant” net emissions increase. Midwest Grain’s
    facility was considered a major source for particulate matter at the time it constructed a
    fluidized bed boiler in 1982. A net particulate matter emissions increase is “significant” if it
    results in an increase of 25 tons or more of particulate matter emissions per year. PSD
    regulations require the use of the “best available control technology” (BACT) in any
    modification to a major source.
    The Attorney General claims, in count I of the complaint, that Midwest Grain violated
    PSD regulations, specifically, 40 CFR 52.21(j), by constructing the dryers without conducting
    a BACT analysis and obtaining a PSD permit, and consequently Section 9.1(d) of the Act,
    which prohibits any person from violating regulations adopted under the federal Clean Air Act.
    The Attorney General also claims that Midwest Grain has violated Section 9(a) of the Act and
    35 Ill. Adm. Code 201.141 by causing or tending to cause air pollution (count II), Section
    9(b) of the Act by operating in violation of construction permit conditions (count III), and
    Section 9(b) of the Act and 35 Ill. Adm. Code 201.143 by operating without an operating
    permit after expiration of the construction permits.
    AFFIRMATIVE DEFENSES
    Against the foregoing alleged violations, Midwest Grain asserts, at pages 6-7 of its
    “Answer,” the following affirmative defenses:
    A.
    Midwest Grain discontinued use of its fluidized bed coal boiler in 1994.
    At the time the coal boiler use was discontinued, Midwest Grain ceased
    its status as a “major stationary source” and the PSD program
    requirements were no longer applicable to Midwest Grain.
    B.
    Midwest Grain acted in good faith and built an emission control system
    for its grain dryers which was designed to restrict emissions from the
    dryers to a level below the level for a “major modification” subject to
    PSD program requirements. This emission control system was reviewed
    and approved by the [Agency] as part of Midwest Grain’s construction
    permit application. Through no fault of Midwest Grain, the system did
    not function as designed and has had difficulty in restricting the emission
    of very small particles. Midwest Grain has worked steadily to improve
    upon the emission control system. Midwest Grain has been in frequent
    contact with [the Agency] regarding its difficulties with the system. To

    3
    the extent Midwest Grain is in violation of PSD regulations, the Act or
    its permit terms, if at all, the violation is due to an unavoidable mistake
    in that its emission control equipment has failed to live up to its design
    specifications.
    C.
    Pursuant to discussions with [the Agency], Midwest Grain has agreed to
    purchase and install additional emission control equipment, at substantial
    expense. Midwest Grain’s commitment to [the Agency] to install new
    emission control equipment constitutes a Compliance Commitment
    Agreement. Midwest Grain is in compliance with the Compliance
    Commitment Agreement, therefore, these allegations should not have
    been brought.
    D.
    Midwest Grain filed an application for an operating permit on March 16,
    1995. To date, [the Agency] has not acted upon the operating permit
    application, although Midwest Grain has extended the review period for
    the operating permit application three times (the last time for an
    indefinite period). Midwest Grain has also filed an application for a
    Clean Air Act Permit. Midwest Grain has been in frequent contact with
    [the Agency] and [the Agency] has not alleged that an operating permit
    is required at this time. At no time has Midwest Grain disregarded the
    provisions of the Board’s air permit regulations and it has worked
    steadily with [the Agency] to remedy the difficulties it has had as a result
    of the unexpected difficult engineering for its emissions.
    ANALYSIS
    Affirmative Defenses Stating Legal Conclusions
    The Attorney General has challenged all of Midwest Grain’s affirmative defenses on
    the grounds that they state legal conclusions. The Attorney General has provided minimal
    arguments in support of this assertion, and inasmuch as each of the defenses quoted above
    includes factual assertions, the Board concludes that this objection is not valid. Many
    affirmative defenses (i.e., waiver, estoppel, laches, statute of limitations) may involve,
    ultimately, a conclusion of law. Any such conclusion, however, must be predicated on facts,
    and as long as the requisite facts are set forth as required by 35 Ill. Adm. Code 103.122(d)
    2
    then the defense is properly pleaded, notwithstanding that the resolution of the defense may
    involve a conclusion of law, and that the defense may be couched in terms of a legal theory.
    2
    35 Ill. Adm. Code 103.122(d) provides:
    Respondent may file an answer within 30 days of receipt of the complaint. All material
    allegations of the complaint shall be taken as denied if not specifically admitted by answer, or
    if no answer is filed. Any facts constituting an affirmative defense which would be likely to
    take the complainant by surprise must be plainly set forth prior to hearing in the answer or in a
    supplemental answer filed pursuant to Section 103.210(b).

    4
    Although the provisions of the Code of Civil Procedure do not apply to proceedings
    before the Board, parties may, in the absence of a specific provision in the Board’s procedural
    rules to govern a specific situation, argue that a particular provision of the Code of Civil
    Procedure provides guidance to the Board. 35 Ill. Adm. Code 101.100(b). Both the Attorney
    General, in the “Motion to Strike Respondent’s Affirmative Defenses,” and Midwest Grain in
    its response, have cited to the Board Section 2-613(d) of the Code of Civil Procedure (735
    ILCS 5/2-613(d) (1997)), which provides:
    The facts constituting any affirmative defense, . . . and any defense which by
    other affirmative matter seeks to avoid the legal effect of or defeat the cause of
    action set forth in the complaint, . . . in whole or in part, and any ground or
    defense, whether affirmative or not, which, if not expressly stated in the
    pleading, would be likely to take the opposite party by surprise, must be plainly
    set forth in the answer or reply.
    The Board believes that this section of the Code of Civil Procedure does provide guidance
    regarding the pleading of defenses, but does not, contrary to the Attorney General’s
    interpretation, preclude pleading of a defense which may include a legal conclusion. We note
    the discussion of this section by the appellate court in Handelman v. London Time, Ltd., 124
    Ill.App.3d 318, 320, 464 N.E.2d 710, 712 (1st Dist. 1984):
    Clearly the purpose of the above-quoted language is to specify the disputed legal
    issues before trial. The parties are to be informed of the legal theories which
    will be presented by their respective opponents. This is a prime function of
    pleading.
    Allowing pleading of defenses which may include legal conclusions will serve to
    inform parties of the legal theories to be presented by their opponents, as well as preventing
    any confusion as to whether a defense has been waived by not having been raised. Given that
    the line between assertions of fact and conclusions of law can be blurry and that consequently
    it can be difficult to determine ahead of time whether a defense is grounded in facts or a
    conclusion of law, and given that the penalty for failure to assert facts constituting a defense is
    extreme, the Board believes the better route is to allow liberal pleading of defenses.
    We turn then to the Attorney General’s specific objections to each affirmative defense
    raised by Midwest Grain.
    Specific Affirmative Defenses
    First Affirmative Defense. The Attorney General has not raised any substantial
    objection to Midwest Grain’s first affirmative defense other than that it states a legal
    conclusion. Midwest Grain sets forth a fact in its defense which may have taken the Attorney
    General by surprise at hearing, namely, that it discontinued use of its fluidized bed coal boiler
    in 1994, and a theory of defense, i.e., that it is no longer a “major stationary source” subject
    to the PSD program. Since this, if true, would at least partially defeat the cause of action

    5
    underlying count I of the Attorney General’s complaint, the Board concludes that Midwest
    Grain’s first affirmative defense is properly pleaded, and it will not be stricken.
    Third Affirmative Defense. The Attorney General objects to Midwest Grain’s third
    affirmative defense, that it is in compliance with the terms of a Compliance Commitment
    Agreement, on the grounds that Section 31(a) of the Act, which deals with Compliance
    Commitment Agreements and which went into effect on August 1, 1996, applies only
    prospectively; that this case is based on a Compliance Inquiry Letter issued by the Agency in
    October of 1995; and that there can therefore be no Compliance Commitment Agreement
    between the Agency and Midwest Grain.
    Whether there is a Compliance Commitment Agreement between the Agency and
    Midwest Grain involves questions of fact which cannot be answered with only the limited
    information in the pleadings in this case. At the very least, with no allegations as to the date
    on which the alleged Compliance Commitment Agreement was reached, the arguments of the
    parties as to the prospective or retroactive effect of the new Section 31(a) are premature. The
    Board concludes that Midwest Grain’s third affirmative defense is properly pleaded; the
    validity of that affirmative defense cannot be tested without evidence not presently before the
    Board. The Board will not strike Midwest Grain’s third affirmative defense.
    Second and Fourth Affirmative Defenses. The Board concludes, however, that the
    Attorney General’s objections to Midwest Grain’s second and fourth affirmative defenses, that
    the defenses do not avoid the legal effect or defeat the causes of action set forth in the
    complaint, are well taken. Midwest Grain’s second and fourth affirmative defenses set forth
    facts which, if proven, would be relevant to the issue of an appropriate penalty rather than the
    liability of Midwest Grain for the violations set forth in the complaint.
    The Board disagrees with Midwest Grain’s characterization of mitigation as avoidance
    in part of complainant’s cause of action. The appropriate penalty to be imposed for a violation
    of the Act is a separate inquiry from whether a violation of the Act has occurred, and
    mitigation issues are only considered once a violation of the Act has been found. An
    affirmative defense is a response to a claim which attacks the complainant’s right to bring an
    action. Farmers’ State Bank v. Phillips Petroleum Co. (Jan. 23, 1997), PCB 97-100, slip op.
    at 2 n.1. Accordingly, as the Board recently ruled in People v. Douglas Furniture of
    California, Inc. (May 1, 1997), PCB 97-133, slip op. at 6, a defense which speaks to
    imposition of a penalty rather than the underlying cause of action is not an “affirmative
    defense” to that cause of action. Midwest Grain’s second and fourth affirmative defenses set
    forth mitigating factors which, if proven, would bear on the appropriate penalty to be
    imposed, but do not impact the question of whether a violation of the Act has taken place.
    The Board thus concludes that Midwest Grain's second and fourth defenses are not proper
    affirmative defenses, and they will be stricken.
    A corollary of this ruling, however, is that since defenses to imposition of a penalty are
    not affirmative defenses, a respondent is not required to set forth in its answer facts relating
    only to the issue of imposition of a penalty which may take the opponent by surprise at

    6
    hearing. Consequently, even though these defenses are stricken, Midwest Grain is not
    precluded from introducing evidence supporting these defenses at hearing.
    CONCLUSION
    For the reasons set forth herein, the motion of the Attorney General to strike Midwest
    Grain’s affirmative defenses is granted as to Midwest Grain’s second and fourth affirmative
    defenses and denied as to Midwest Grain’s first and third affirmative defenses. Midwest
    Grain’s second and fourth affirmative defenses are hereby stricken.
    IT IS SO ORDERED.
