    PROPOSED RULE.
    SECOND NOTICE
    ORDER OF THE BOARD
    (by J.
    ID.
    Dumelle):
    On February 19, 1981 the Board adopted a proposed rule, first
    notice Order in this rulemaking.
    Th.is was published in the Illinois
    Register
    (5
    Ill. Reg. no.
    11,
    p. 2629, March 13, 1981).
    The
    corn—
    iñént period is over.
    In response to comments the Board proposes
    to adopt the language which appears below.
    Changes from the Feb-
    ruary 19 Order are indicated by striking out and underlining.
    The
    Clerk is directed to initiate the second notice period.
    Subpart A:
    General Effluent Standards
    Rule 400
    Preamble
    This part prescribes the maximum concentrations of various contam-
    inants which may be discharged to the waters of the State.
    Subpart
    A prescribes standards of general applicability.
    Site specific
    rules and particular exceptions are found in Subpart B.
    Rule 401

    the basis of one or more of the following averaging rules:
    1)
    The—evef~ge—of—~e—er—rnore—~w—we~ge~—~4—he~r—epe,4te

    Terms used in Rule 401(c)
    shall have the following meanings:
    1)
    The monthly average shall be the numerical average of all
    daily composites taken during a calendar month.
    A monthly
    average must be based on at least three daily composites.
    2)
    A daily composite shall be the numerical avera~eof all
    grab samples, or the result of analysis of a single sample
    formed by combining all aliguots,
    taken
    during a calendar
    day.
    A daily composite must be based on at least three
    grab samples or three aliguots taken
    at different times.
    3)
    A grab sample is
    a sample taken at a sin9le time.
    Ali-
    guots of a daily composite are grab samples only if they
    are analyzed separately.
    e)
    Rule 401(c)
    establishes a method of interpretation of the ef-
    fluent standards of this Part.
    The Agency shall consider the
    averaging rule in deciding whether an applicant has demon-
    strated that a facility complies with this Part for purposes
    of permit issuance and in writing the effluent standards into
    permit conditions.
    Reporting and monitoring requirements are
    established by way of permit condition pursuant to Rules 501
    and
    10(f)
    f)
    Proof of violation of effluent
    limitations contained in permits
    shall be based on the language of the permit.

    The Agency may impose permit conditions neces-
    sary or required to assure continued application of an excep-
    tion.
    When paragraph
    (b)

    Rule 412
    New Source Performance Standards
    The
    numerical effluent standards of this Part do not apply under

    The
    discharge
    is authorized by an NPDES permit;
    and
    b)
    The facility from which the discharge results
    is subject to
    new source performance standards promulgated by USEPA pursuant
    to the Clean Water Act; and
    c)
    The NPDES
    permit
    contains
    a
    numerical
    effluent
    limitation
    based
    upon USEPA effluent guidelines and standards representing best
    available demonstrated control technology for the constituent
    in question.

    a)
    Except as provided below no person shall cause
    or allow the
