    PROPOSED RULE.
    SECOND NOTICE.
    OPINION AND ORDER OF THE BOARD
    (by R.
    C. Flemal):
    The Board
    by Order of December
    6,
    1989 created this Docket
    in the R88-2l proceeding
    for the purpose of allowing
    further
    consideration of certain adjuncts
    to the overall water
    toxics
    control regulations
    as adopted
    in Docket A of R88—21
    (See Final
    Opinion and Order, January
    25,
    1990).
    First Notice of Docket B
    was adopted by the Board on December
    6,
    1989;
    publication
    occurred at
    13
    Ill.
    Reg.
    20230 et
    seq.
    The First Notice Docket B proposal considered amendments
    to
    seven different Sections
    in five separate Parts of
    the Board’s
    water pollution control regulations.
    The general
    subject matter
    of the six amendments are as follows:
    Section 302.208
    General Use dissolved
    iron water quality
    standard
    Section 302.211
    Mixing zones
    for thermal discharges
    Section 302.304
    Public and Food Processing water
    dissolved iron standard
    Section 303.354
    Horseshoe Lake mixing zone and ZID
    Section 304.211
    Exception
    for intermittent discharges
    of
    total residual chlorine
    Section
    305.102
    Reporting
    requirements
    Section
    309.152
    Compliance schedules and stays
    Today the Board sends
    certain portions
    of the Docket
    B
    amendments
    to Second Notice,
    as discussed below.
    PUBLIC COMNENTS
    The Board has received five Public Comments
    (“PC”)
    on the
    First Notice proposal.
    These are as
    fo11oc~is:
    PC
    36
    Illinois Steel Group (“Steel Group”)
    PC
    37
    Illinois Environmental Regulatory Group
    (“IERG”)
    PC 38
    Pekin Energy Company
    (“Pekin”)
    PC 40
    Illinois Environmental Protection Agency “(Agency”)
    PC
    41
    United States Environmental Protection Agency,
    Region
    5
    “(USEPA”)

    —2--
    The Board notes
    that
    a portion
    of the IERG Public
    Cornnient,
    rather than addressing Docket
    B,
    addresses
    itself
    to repeal,
    reconsideration, and modifications of final actions taken
    in
    Docket A.
    The Board is not persuaded that these portions of the
    IERG Public Comment
    raise
    issues sufficient
    to warrant any of the
    actions requested by IERG.
    GENERAL USE DISSOLVED IRON WATER QUALITY STANDARD
    In Docket A the Board deleted the Total
    Iron General Use
    Water Quality Standard found at Section 302.208(e).
    This action
    was based upon the conclusion that
    the total
    iron standard
    is
    relatively meaningless from all environmental and health
    perspectives.
    Among other matters,
    total
    iron
    is predominantly
    present
    under ambient conditions
    as particulate
    iron compounds
    which
    are unavailable
    to aquatic
    life.
    However,
    the Board continued
    to consider whether
    there
    should be adopted an alternative
    to
    the total iron standard.
    To
    that end the Board proposed for First Notice
    in Docket B a
    General Use Standard for dissolved
    iron at
    Section 302.208(e).
    At First Notice the Board observed:
    Whereas
    there
    is
    no known documentation for the
    aquatic toxicity of total
    iron at ambie~it
    concentrations, there
    is evidence that dissolved
    iron
    in concentrations of
    less than
    1 mg/l
    is toxic
    to
    at
    least certain aquatic organisms
    (R2.
    at
    698—700,
    759—
    60;
    Exh.
    87).
    Additionally, there
    is substantive
    evidence
    that aquatic degradation accompanies even
    moderate concentrations of dissolved
    iron
    (R2.
    at
    764).
    Upon review of these data,
    the Board concurs
    with the Agency,
    for the purpose of First Notice,
    that a General Use dissolved
    iron standard
    is
    necessary
    for the protection
    of
    Illinois waters.
    The
    standard the Board today adopts
    for First Notice
    is
    0.2 mg/i, which
    the Board believes comports with the
    best available data on iron toxicity and ecological
    damage.
    (R88—21 Docket
    B,
    December 6,1989,
    p.
    2).
    The only Public Comment which addresses the merits
    of this
    matter
    is the Steel Group’s comment.
    The Steel Group contends
    that
    (a)
    the proposed standard has an inadequate scientific
    basis, and
    (b) compliance with
    the proposed standard will impose
    an unreasonable hardship on
    Illinois
    industries
    (PC
    36
    at
    9—
    13).
    The Steel Group further proposes that
    the dissolved iron
    standard be 1.0 mg/b
    As regards the scientific
    basis
    for
    a 0.2 mg/i dissolved
    iron standard,
    the Steel Group observes that
    the record before
    the Board contains only two discussions
    of
    the toxicity of
    110—448

    —3—
    dissolved
    iron.
    One of these consists of a 1988 study conducted
    in Denmark, the results of which have been questioned
    by Mr~
    Thomas Simpson, one of
    the Steel Group’s witnesses
    (see R2.~at
    1344—5)
    The second of these is contained
    in the “Red Book”,
    USEPA’s 1976 compendium of
    recommend criteria for water, wherein
    there
    is little relevant data on the toxicity of dissolved
    iron.
    The Steel Group concludes
    that this information
    is
    collectively old, concerns non—native species, and involves
    suspect field procedures
    (PC 36 at
    10).
    The Board believes
    that the Steel Group’s observations
    regarding
    the lack of
    technical support
    for a 0.2 mg/i dissolved
    iron standard are persuasive.
    Indeed,
    the Board
    is impressed
    with the apparently very limited data on the toxicity of
    dissolved
    iron, particularly
    in light of the ubiquity of this
    substance.
    On this basis,
    the Board will not proceed with the
    numeric limitation proposed at First Notice.
    Nevertheless,
    the Board continues
    to believe
    that
    environmental protection would not
    be adequately served
    in the
    total absence of
    a General Use iron standard.
    The Board
    accordingly today proposes
    a General Use standard of 1.0 mg/i,
    measured as dissolved iron,
    as recommended by the Steel Group
    (PC
    36 at
    13).
    The Board notes
    that this value
    is also the value
    recommended for iron generally
    in the “Red Book” and
    is same
    value previously employed for
    total
    iron.
    The Board
    is not necessarily fully comfortable with this
    outcome, but it does believe
    that
    1.0 mg/i presents the only
    standard defensible
    in the record before the Board.
    The Agency
    is,
    of course, welcome
    to institute an amendatory rulemaking
    at
    any time
    ic believes
    it has sufficient documentation
    to- support
    an alternate standard.
    As a procedural matter,
    the Board notes
    that
    at First Notice
    the dissolved
    iron standard was proposed as an amendment
    to
    the
    then current version of Section 302.208.
    In the time since First
    Notice, Section
    302.208 has undergone other amendments
    as part
    of
    the Docket A proceeding.
    Today’s proposal
    is accordingly
    presented as
    an amendment of the now current version of Section
    302.208 as adopted
    in Docket
    A.
    1 As noted
    in the Board’s earlier Opinions
    in this matter,
    page
    numbering of the hearing transcriDts was
    reset beginning with the
    hearing held on June 13,
    1989.
    Th conformity with the
    previously—used style,
    transcripts
    of that and subsequent dates
    are herein referenced

    MIXING ZONES FOR THERMAL DISCHARGES
    At First Notice the Board had proposed the following
    addition at
    35
    Ill.
    Adm.
    Code 302.211(k):
    k)
    The temperature standards
    of
    this Section shall
    apply outside
    a zone of mixing which shall have
    an area no greater
    than a circle with
    radius
    of
    183 meters
    (600 feet)
    or an equal area of simple
    form.
    This proposal was advanced upon
    the recommendation
    of IERG
    and over the objection of
    the Agency.
    In making the First Notice
    proposal the Board noted that
    “~while
    the Board
    is not yet
    convinced of either the need for nor the desirable effect
    of the
    proposal,
    the Board does believe
    that further exploration of the
    issue
    is
    justified”
    (R88—21 Docket
    3,
    December
    6,
    1989,
    p.
    2)
    IERG’s principal concern appears
    to be that
    the allowed
    mixing provisions of Section
    302.102,
    as adopted
    in Docket A,
    are
    directed toward toxic substances,
    and thereby
    do not recognize
    the special character
    of thermal discharges.
    As IERG has pointed
    out,
    “tihe
    impact
    of heat
    ...
    may
    be quite different than that
    of
    toxic chemicals and may,
    in some instances,
    even be
    beneficial”
    (R2.
    at
    742).
    In response
    to this
    concern,
    the Board
    observed at First Notice:
    While
    the Board does not believe
    that the Section
    302.102(b)
    limitations are necessarily tailored
    entirely
    to limiting the impact
    of toxic chemicals,
    the Board can nonetheless appreciate
    the unique
    nature of thermal discharges
    in this context.
    The
    Board does not necessarily see,
    however, how IERG’s
    proposed language would address
    the potential
    inapplicability
    of any provision of Section
    302.102(b)
    to thermal discharges.
    ..
    .the Board
    questions whether
    the proposed language
    is
    unnecessarily redundant...
    (R88—2
    Docket
    B,
    December
    6,
    1989,
    p.
    3).
    The Agency also now observes,
    as
    it did prior
    to First
    Notice
    (see PC
    25
    at
    19),
    that proposed 302.211(k):
    is
    rather redundant
    in that
    it repeats
    a
    condition of mixing zones stated
    in
    Section
    302.102.
    There
    is
    no provision
    in the proposed
    302.211(k) 1anguaae~ that would serve to circumvent
    any limiting provison of
    the mixing zone rule.
    As
    such,
    the Agency believes
    that this addition
    is
    neither beneficial
    nor harmful.
    (PC 40
    at
    1—2).
    110—450

    —5—
    IERG now also seems
    to agree with
    the Agency.
    IERG notes:
    The Board’s
    First
    Notice) Opinion seems to
    ...
    not
    so much question the justification for Section
    301.211(k),
    as
    it wonders how 302.211(k) prevents
    302.102(b)
    from being applied
    to thermal
    discharges.
    As a result,
    IERG has reeexamined both
    302.102(b)
    and 302.211(k),
    and finds
    it must agree
    with the Board’s view of the situation.
    (PC #37,
    Exhibit A).
    Based on these perspectives,
    the Board believes that
    Section
    302.211(k)
    serves no beneficial purpose,
    and accordingly will
    today delete
    it from the Docket B proposals.
    As a final matter,
    the Board notes
    that IERG now urges
    the
    addition of
    an introductory clause at
    Section 302.102(b)
    as
    follows
    (PC 37, Exhibit A):
    b)
    Except
    as otherwise provided
    in this Chapter with
    respect
    to temperature,
    rpthe portion, volume and
    area of any receiving waters within which mixing
    is allowed pursuant
    to subsection
    (a)
    shall
    be
    limited by the following:
    The Board believes that this addition serves marginal,
    if
    any,
    purpose.
    Accordingly,
    the Board declines
    to proceed with
    it at
    this time.
    PUBLIC AND FOOD PROCESSING WATER DISSOLVED IRON STANDARD
    At First Notice the Board proposed a Public and Food
    Processing Water Supply Standard for dissolved iron of 0.3
    mg/l.
    The Board noted
    that the amendment was occasioned because
    the deletion of total
    iron
    from the General Use Standards was
    also an effective deletion of
    total iron from the Public and Food
    Processing Water Standards,
    pursuant
    to the cumulative
    relationship of
    the Public and Food Processing Water Standards
    with the General Use Standards found at
    35 Ill.
    Adm. Code
    302.301.
    The 0.3 mg/i standard
    is that recommended by
    the USEPA
    in the “Red Book”
    as
    the limit beyond which conventional
    surface
    water systems are unable
    to consistently
    reduce higher levels of
    dissolved
    iron
    to aesthetically acceptable levels
    (R2.
    at 730—
    1).
    In this sense,
    it
    is
    not
    a health—limited standard.
    The only Public Comment addressing
    this matter
    is the
    Agency’s.
    The Agency recommends
    that the Board
    not proceed with
    this amendment on the basis
    that
    it
    is unnece~sary under
    the
    assumption
    that the General Use Standard would be set at
    0.2 mg/l
    as proposed at
    First Notice
    (PC
    40
    at
    1).
    However,
    as
    noted
    above,
    the Board today declines
    to proceed with the 0.2 mg/i
    General Use proposal.
    Under
    this circumstance,
    the Board
    110—451

    —6—
    believes that the Public and Food Processing Water Supply
    Standard as proposed at First Notice continues
    to constitute
    the
    proper action.
    This proposal will accordingly be moved
    to Second
    Notice.
    HORSESHOE LAKE MIXING ZONE AND ZID
    At First Notice of Docket A the Board proposed what
    is
    in
    effect
    a site—specific mixing zone rule applicable
    to discharge
    from Granite City Division of National Steel Corporation
    (“GCD”)
    to Horseshoe
    Lake.
    Subsequently,
    the Board
    transferred
    the
    proposal
    to Docket B and sent
    it
    to First Notice there.
    The
    Board now notes
    that GCD has filed
    an essentially identical
    proposal
    in an Adjusted Standard proceeding:
    In the Matter
    of:
    Granite City Division
    of National Steel Corporation,
    AS 90—4.
    As the Board noted during
    the First Notice
    of Docket
    B,
    “there
    is question as
    to whether GCD’s concerns are
    in fact best
    addressed via a site—specific rule”
    (P88—21 Docket
    B,
    December
    6,
    1989,
    p.
    4).
    The Board now concludes that
    the site—specific
    mode,
    as provided by GCD’s adjusted standard proceeding,
    does
    in
    fact present
    the best forum for this matter.
    Accordingly,
    the
    GCD proposal willbe
    today deleted
    from Docket
    B.
    EXEMPTION FOR INTERMITTENT DISCHARGES OF TOTAL RESIDUAL CHLORINE
    At First Notice
    the Board proposed,
    on the
    joint
    recommendation of IERG and the Agency,
    a exemption
    rule for
    intermittent discharges
    of
    total residual chlorine
    (“TRC”).
    The
    Board accepts now,
    as
    it did
    at First Notice,
    that
    the proposed
    rule
    is a necessary adjunct
    to
    the adoption
    in Docket A of
    a
    General Use Water Quality Standard for
    TRC.
    The Board will not repeat here the justification for the
    exemption
    rule;
    the intexested person
    is directed
    to the First
    Notice Opinion,
    p.
    4—5.
    Rather,
    the Board notes
    that
    the most-
    First Notice Public Comments are generally supportive
    of the rule
    as proposed at First Notice.
    An exception
    is
    the position
    expressed
    by the USEPA, which recommends
    that each consideration
    of
    intermittent chlorination
    be treated as an
    individual
    site—
    specific determination
    (PC
    41
    at p.3).
    Given the degree of
    technical and economic support
    for
    a rule—of—general-
    applicability,
    the Board
    is
    convinced that USEPAs
    site—specific
    strategy would
    lead
    to an unwarranted drain on
    the resources of
    the regulated community and the
    State.
    The Board accordingly
    declines
    to accept USEPA’s suggestion.
    Pekin,
    which supports the general
    concept
    of an exemption
    rule,
    believes that
    the proposed
    rule does not go sufficiently
    far
    (PC #38).
    Specifically, Pekin would have the Board add the
    following sentence at the end of
    the rule as proposed:
    11 0—452

    —7—
    Provided, however,
    that this provision shall not
    prevent facilities
    from receiving greater limits
    in
    terms of the duration of chlorination
    and the amount
    of chlorine allowed
    in the effluent upon their making
    a reasonable showing to the Agency that such greater
    limits are required
    to prevent biofouling and that
    such limits will not produce effects
    in the receiving
    stream that are appreciably different from the effects
    that would
    result from chlorination
    by the facility
    that complied with the proposed exception.
    (Id.
    at
    4).
    The Board
    notes
    that Pekin’s proposed addition constitutes
    (with
    the salient exception of the roles played by the Board
    versus the Agency)
    essentially an adjusted standard level
    of
    justification
    in accord with Section
    28.1
    of
    the Illinois
    Environmental Protection Act
    (“Act”)
    and
    35
    Ill. Adm.
    Code
    301.108.
    While
    the Board has
    no objection
    to specifying levels
    of justification within the body of
    individual
    rules, pursuant
    to
    Section
    28.1(b)
    of
    the Act,
    the Board notes
    that the general
    level of justification procedures of Section 28.1(c)
    would
    seemingly cover
    the particular justifications
    requested by
    Pekin.
    In addition,
    the Board has substantial question as
    to
    whether
    the roles contemplated
    by Pekin
    for the Agency and the
    Board are indeed the proper roles.
    For these reasons,
    the Board
    does not believe
    that Pekin’s particular proposal has been
    sufficiently explored
    to allow
    it
    to proceed at
    this time.
    As
    a procedural matter,
    the Board notes
    that the exemption
    procedure as proposed at First Notice was placed at
    35
    Ill.
    Adm.
    Code 304.221.
    This section number was at the time unused.
    However,
    the number
    has been subsequently preempted
    in another
    proceeding.
    Accordingly,
    today the intermittent chlorination
    exemption
    is placed
    in the next available section, Section
    304.222.
    REPORTING REQUIREMENTS
    The Board at First Notice proposed amendments recommended by
    IERG at
    Section 305.102(d) and
    (e),
    the principal intention of
    which was
    to clarify
    the status
    of
    a permittee regarding
    legal
    action by
    a third party.
    The language as proposed was as
    follows:
    d)
    If the Agency specifies,
    as a permit condition,
    that information be provided regarding
    the
    biological
    impact of
    a discharge,
    then such
    information shall be provided
    in accordance with
    a
    schedule of compliance pursuant
    to Section
    309.138.
    110—453

    —8—
    e)
    When
    a permit
    is conditioned pursuant
    to
    subsection
    (d) and the permittee
    is
    in compliance
    with such condition,
    there shall be
    no cause of
    action against
    the permittee for violations of
    toxicity
    in the receiving stream as
    a result
    of
    the permitted discharge.
    The Public Comments which address this matter focus
    on
    proposed subsection
    (e),
    upon which
    they take
    rather strongly
    divergent views.
    The Steel Group,
    with IERG support
    (PC 37
    at
    8), contends that
    the proposal
    is flawed
    in not ~oing
    far enough
    (PC 36 at
    5—7).
    The Agency and the USEPA contend
    that the
    concept expressed
    in the proposal
    is inherently flawed
    (PC
    40 at
    4;
    PC
    41 at
    3—4).
    Among
    the comments,
    the Board believes that
    the Agency’s perspective
    is particularly
    telling:
    As proposed,
    Section 305.102(e)
    would provide an
    automatic variance once the permittee met the
    conditions
    of
    Section 305.102(d).
    Permit conditions
    requiring monitoring
    per Section 305.102(d)
    could
    be
    for any number
    of concerns
    (biological assessment,
    chemical analysis, dilutions studies,
    etc.).
    However,
    to allow the permittee protection from
    enforcement
    of
    the toxic water quality standards
    insulates the permittee from any number of toxic
    water quaity conditions
    that may or may not
    be
    related to the parameters,
    concerns and operations
    associated with the permit conditions.
    This proposal
    would also protect the discharger
    from toxic spills
    and even intentional toxic discharges.
    Clearly,
    this
    proposal
    is contrary
    to the current effluent and
    water quality provisions of Subtitle
    C,
    the
    Environmental Protection Act and Section 301(b)(l)(C)
    of
    the federal
    Clean Water Act;
    the latter federal
    statutue requires and recognizes continuous
    compliance with water quality standards.
    Furthermore,
    any variance or adjusted standard must
    be approved by U.S. EPA pursuant
    to Section
    303(c)(2)(A).
    Section 305.102(e)
    as proposed
    constitutes an automatic variance which
    is -~:ithout
    procedures
    to generate a record necessary to meet
    U.S.
    EPA Water Quality Standards regulations.
    Although the Board continues
    to see that clarification of
    the status of a permittee regarding third party challenges may be
    desirable,
    the Board fails
    to see how Section
    305.102(e)
    can be
    successfully remedied
    to effectuate
    this goal.
    Additionally,
    the
    Board see no particular
    need
    for Section
    305.103(d)
    in
    the
    absence of Section 305.102(e).
    Accordingly,
    the Board will not
    proceed with this matter
    at this time.

    COMPLIANCE SCHEDULES AND STAYS
    At First Notice of Docket B the Board proposed amendments
    to
    Section 309.152(b)
    intended to clarify an NPDES permit holder’s
    rights
    to being deemed
    in compliance under
    the circumstance where
    compliance with Sections 302.208 or 302.210 subjects the NPDES
    permit
    to modification.
    A special feature of
    the Board’s
    proposal was a defined period of stay of
    the application of
    Sections 302.208 and 302.210 during the period when the permit
    was being modified.
    The Board’s First Notice proposal
    is generally viewed
    negatively
    by
    the public commenters
    (see PC
    36
    at
    7—8;
    PC
    37 at
    5—7;
    PC 40 at
    4—5).
    The Board accepts
    these comments as
    indicative
    of the unworkability of
    the direction proposed at
    First Notice.
    Accordingly,
    that proposal
    is today deleted from
    this proceeding.
