    12 and
    13 of the Environmental Protection Act
    (Act),
    which empower the Board to designate equipment o~
    facilities capable of causing or contributing to
    water pollution;
    to set standards for the issuance
    of permits
    for the construction, installation and
    operation and for the inspection of said equipment

    Act of 1972
    (FWPCA),
    as amended,
    (33 U.S.C. §1251
    et
    ~J,
    the Board adopts the following rules and
    regulations.
    102
    Policy
    A policy of the General Assembly in adopting the
    Act is to restore, maintain and enhance the
    purity of the waters of Illinois in order to pro-
    tect health, welfare, property and the quality of
    life.
    It is determined that mining activities
    including the preparation, operation and abandon-
    ment of mines, mine refuse areas and mine related
    facilities without environmental planning and
    safeguards and the use
    of certain refuse materials
    can cause, threaten or allow the discharge of
    contaminants into the waters of Illinois so as to
    cause or threaten to cause
    a nuisance or to render
    such waters harmful or detrimental to public health,
    safety or welfare or to domestic, commercial,
    industrial,
    aqricultural, recreational or other
    legitimate uses including use
    by
    livestock, wild
    animals, birds,
    fish or other aquatic
    life and
    riparian vegetation.

    103
    Purpose
    The purpose
    of this Chapter is to prevent pollu-
    tion of waters of Illinois caused by failure to
    plan proper environmental safeguards for the loca-
    tion, preparation,
    operation and abandonment of
    mining activities, mining and mine refuse operations.
    A permit system is established to
    ~e-tha~-~e~
    ~
    control
    the multitude of contaminating point and non-point
    source discharges, visible and hidden, continuous
    and fluctuating, which are potentially present in
    mining activities, mining and mine refuse operations.
    In order
    to ensure that such activities meet environ-ET?1 w?159 511 m?542 511 l?S?BT?
    mental standards W~er water quality and effluent
    standards are established to limit discharges from
    point sources
    as well
    as
    to protect waters for bene-
    ficial uses.
    In addition, procedural safeguards are
    established to ensure the protection of waters.
    Furthermore,
    it is the purpose of this Chapter to
    meet the requirements of Section 402 of the FWPCA.
    104
    Compliance with Other Laws Required
    Nothing in this regulation
    is intended to be
    inconsistent with or impair the obligation to
    comply with the provisions of an Act entitled,
    “The Surface Coal Mining Land Conservation and Re-
    clamation Act” of Illinois or with any other state
    or federal law affecting the duties of an operator.
    105
    Validity Not Affected
    If any provisions

    or if the application to any person or in any circum-
    stances
    is adjudged invalid, such invalidity shall

    shall
    notify
    the Agency in writing
    by certified mail within thirty days of any of
    the
    following:
    (1)
    Abandonment:
    or
    (2)
    Cessation or suspension of active mining
    for thirty days or more unless caused by
    a labor dispute.
    (b)
    During cessation or suspension of active mining,
    whether caused by a labor dispute or not,
    the
    cermittee shall provide whatever interim impound-
    ment, drainage diversion and wastewater treatment
    is necessary to avoid
    rec~e~edviolations
    of
    the Act or Chapter
    4.
    Cc)
    Upon abandonment the permittee shall execute
    and complete the permitted abandonment plan;
    provided,
    however, that the permitee need
    not execute and complete the permitted aban-
    donment plan if the abandonment arises solely
    from transfer of ownership
    to
    a responsible
    party.

    —23—

    of
    the
    obligation
    of
    further
    executing
    the
    abandonment
    plan.
    Ce)
    Upon request by the permittee the Agency shall
    issue a certificate of abandonment whenever an
    abandonment plan has been satisfactorily executed.
    Refusal
    to issue a certificate of abandonment is
    a permit denial
    for purposes of appeal.

    composite samples averaged over any calendar
    month.
    In
    addition,
    no

    no single grab sample
    shall exceed two times the numerical standards
    prescribed
    in
    this
    part.
    602
    Sampling, Reporting and Monitoring
    (a)
    Where treatment is provided for a discharge,
    effluent samples shall be taken at a point
    after the final treatment process and before
    entry into or mixture with any waters of the
    state.
    (b)
    Where treatment is provided the oermittee shall
    design or modify structures
    so
    as to permit the
    taking of effluent samples by the Agency at the
    required point.
    (c)
    Where treatment
    is not provided for a discharge,
    effluent samples shall be taken at the nearest
    point of access to the discharge source at a
    point where the discharge leaves the mine or
    mine refuse area or other portions of the
    affected land, but in all cases effluent
    samples shall be taken before entry into or
    mixture with the waters of the state.
    (d)
    At a reasonable frequency to he determined by
    the Agency,
    the permittee shall report the
    actual concentration or level of any parameter
    identified in the state or NPDES permit.
    Ce)
    The Agency may by permit condition require
    monitoring and reporting on the basis
    of 24-
    hour composite samples averaged over calendar
    months.
    However, grab samples or composite
    samples
    of shorter duration may be permitted
    by the Agency after demonstration that such
    samples reflect discharge levels over standard
    operating conditions.
    (f)
    Subsection
    (e)
    of this Rule notwithstanding, if
    a permittee so requests,
    the Agency shall by
    permit condition require monitoring and reportiflg
    on the basis of grab samples, in which case Rule
    601(b) will apply.

    604
    Background Concentrations
    Because the effluent standards
    in this part are
    based upon
    concentrations
    achievable
    with
    conven-
    tional treatment technology that is largely un-
    affected by ordinary levels of contaminants
    in in-
    take water,
    they are absolute standards that must
    be
    met
    without
    subtracting
    background
    concentra-
    tions.
    However,
    it is not the intent of these
    regulations
    to require users
    to clean up contami-
    nation caused essentially by upstream sources or
    to require treatment when only traces of contami-
    nants are added to the background.
    Compliance with
    the numerical effluent standards
    is therefore not
    required when effluent concentrations in excess of
    the standards result entirely from the contamina-
    tion of influent before it enters the affected
    land.
    Background concentrations or discharges
    upstream from affected land are rebuttably
    presumed not to have caused a violation of this
    part.
    Dilution
    (a)
    Dilution of an effluent from a treatment works
    or from any wastewater source
    is not acceptable
    as
    a method of treatment of wastes in order to
    meet the standards set forth
    in this part.
    Rather,
    it shall be the obligation of any person
    discharging contaminants of any kind to the
    waters of the state to provide the best degree
    of treatment of wastewater consistent with
    technological feasibility, economic reasonable-
    ness and sound engineering judgment.

    -27—
    (b)
    In
    making
    determinations
    as
    to
    what
    kind
    of
    treatment is the best degree of treatment
    within
    the
    meaning
    of
    this
    paragraph,
    the
    following
    will
    be
    considered:
    (1)
    What degree of waste reduction can be
    achieved by process change, improved
    housekeeping and recovery of individual
    waste
    components
    for
    reuse;
    and
    (2)
    Whether individual process wastewater
    streams
    should
    he
    segregated
    or
    combined.
    (c)
    If necessary the concentrations
    so measured
    shall
    be
    recomputed
    to
    exclude
    the
    effect
    of
    any
    dilution
    that
    is
    improper
    under
    this
    rule.
    605
    Violation of Water Quality Standards
    In addition to the other requirements of this part,
    no mine discharge or non—point source mine discharge
    ~ei~
    shall,
    alone or in combination with other
    sources, cause
    a violation of any water quality
    standards of Chapter
    3:
    Water Pollution.
    When the
    Agency
    finds
    that
    a
    discharge
    which
    would
    comply
    with
    effluent
    standards
    contained
    in
    this
    part
    would
    cause or
    is causing a violation of water quality
    standards,
    the Agency shall take appropriate action
    under
    Section
    31
    or
    39 of the Act to require the
    discharge
    to meet whatever effluent limits are
    necessary
    to
    ensure
    compliance
    with
    the
    water
    quality
    standards.
    When such a violation
    is caused by the
    cumulative effect of more than one source, several
    sources may be joined in an enforcement or variance
    proceeding and measures
    for necessary effluent re-
    ductions will he determined on the basis
    of techni-
    cal feasibility, economic reasonableness and fairness
    to
    all
    dischargers.
    605.1
    Temporary Exemption from Rule 605
    (a)
    The
    Agency
    may
    by
    permit
    provide
    that
    a
    mine
    discharge shall be exempt from the require-
    ments of Rule
    605 as it applies to the dis-
    charge of total dissolved solids, chloride,
    sulfate, iron and manganese.

    —28—
    (b)
    A permittee may apply for such exemption as
    part
    of

    or
    supplemental
    state
    or NPDES permit.
    (c)
    The
    Agency

    permit
    such
    exemption
    if
    all
    of the following conditions
    are met:
