    ORDER OF THE BOARD
    (by J. Theodore Meyer):
    This
    matter
    is before
    the Board
    on Amerock
    Corporation’s
    (Amerock)
    January
    28,
    1992 request
    for
    clarification.
    Amerock
    seeks
    clarification of the conditions contained
    in the variance
    granted by the Board on January
    9,
    1992.
    Initially,
    Amerock
    advises
    the
    Board
    that
    it
    no
    longer
    anticipates implementing the sanitary sewer option if its requested
    site-specific rule
    (docket R87—33)
    is denied.
    Instead,
    Amerock
    would
    implement the collection and treatment option,
    the source
    abatement option, or a combination of those.
    The Board notes the
    change.
    Additionally,
    Amerock
    states
    that
    all
    eight
    of
    its
    outfalls are permitted under its March 1990 NPDES permit,
    so that
    the reference
    in Condition
    3 to “three unpermitted outfalls”
    is
    incorrect.
    The Board will correct that condition.
    The remainder of Amerock’s request
    for clarification deals
    with interpretation
    of the conditions attached to the variance.
    First, Amerock notes that it cannot provide samples for the entire
    period
    of the variance,
    because
    of the simple passage
    of
    time.
    Therefore,
    Amerock
    states
    that
    it
    will begin
    the
    sampling
    and
    analysis
    required
    by
    the
    variance
    in
    1992.
    Amerock’s
    interpretation is correct.
    Second, Amerock interprets Condition 3
    to
    require
    one
    sample
    from
    each
    outfall
    if
    a
    discharge
    has
    occurred.
    If no discharge has occurred, Ainerock will so st~atein
    its
    Discharge
    Monitoring
    Report
    (DMR).
    Again,
    Amerock’s
    interpretation is correct.
    Ainerock
    also
    requests
    clarification
    of
    several
    issues
    regarding Condition 4.
    First, Amerock interprets Condition
    4 to
    require monthly grab samples and sediment samples from North Kent
    Creek
    regardless
    of
    whether
    discharges
    have
    •occurred.
    That
    interpretation is correct.
    Condition 4, as imposed on January
    9,
    1992,
    requires grab
    samples
    of water
    and sediment upstream and
    downstream of each of Ainerock’s eight outfalls.
    Amerock asks that’
    the condition be modified to allow for sampling in three places.
    130—19
    2
    The Board will modify the condition, but will require samples from
    four
    places.
    This will
    ensure that
    samples
    are taken
    in the
    portions
    of the stream where
    impacts
    are most likely to occur.
    Additionally, Amerock interprets Condition
    4 to require that each
    grab and sediment sample be analyzed for the parameters listed in
    Condition
    2,
    except
    for
    total
    suspended
    solids
    (TSS).
    That
    interpretation
    is
    correct,
    insofar
    as
    Ainerock
    need not
    analyze
    sediment samples
    for
    TSS.
    However,
    the water
    samples must
    be
    analyzed for TSS.
    Fin~lly, Amerock
    interprets
    Condition
    5
    as
    identical
    to
    Condition 6 in its prior variance (PCB 84—62), which was satisfied
    by the semi-annual biological surveys conducted by Huff and Huff,
    Inc.
    That interpretation is incorrect, because biological sampling
    only occurred at points upstream and downstream of the entire group
    of outfalls.
    Instead, the biological sampling shall be done at the
    four sampling points specified in Condition 4.
    The Board will include
    a corrected order setting forth
    the
    modifications discussed above.
    This order supersedes the January
    9,
    1992 order.
    ORDER
    Amerock Corporation
    (Amerock)
    is hereby granted
    a
    variance
    from the following effluent standards located at
    35 I1l.Adin.Code
    304.124:
    hexavalent
    chromium,
    total
    chromium,
    copper,
    cyanide,
    zinc,
    and
    total
    suspended
    solids.
    This
    variance
    applies
    to
    Amerock’s
    facility
    located
    at
    4000
    Auburn
    Street,
    Rockford,
    Illinois, and is subject to the following conditions:
    1.
    This variance begins on December 21, 1987, and expires on
    the earlier of:
    December 21, 1992,
    or the date of final
    action on any grant of Amerock’s requested site—specific
    rule, currently pending before the Board in R87-33.
    2.
    During the period of the variance, Amerock’s discharges
    shall not exceed the following limits:
    Constituent
    Limitation (lbs/month)
    chromium
    (hexavalent)
    1.0
    chromium
    (total)
    4.0
    copper
    20.0
    cyanide
    (total)
    3.0
    zinc
    60.0
    total suspended solids
    300.0
    3.
    In addition to the sampling required by Ainerock’s NPDES
    permit,
    Ainerock shall
    inspect each discharge
    location
    during and shortly after periods of rainfall.
    Amerock
    shall obtain one sample from each outfall per month.
    The
    130—20
    3
    samples shall be analyzed for the parameters required by
    the NPDES permit.
    The results of these analyses shall be
    attached to Ainerock’s DMRs and submitted to the Agency.
    If no discharges occurred during the month, Ainerock shall
    so indicate in its DMR5.
    4.
    Amerock shall sample the water and sediment of North Kent
    Creek once each month at sites:
    (1) upstream of Outfall
    000;
    (2)
    between
    Outfalls
    001
    and
    003;
    (3)
    between
    Outfalls 004 and 007; and
    (4) downstream of Outfall 007.
    This sampling shall occur at a time when discharges are
    present.
    However, even if no discharges occur in a given
    month,
    Amerock
    shall
    take the monthly
    samples
    at the
    locations
    listed
    above.
    These
    samples
    shall
    undergo
    chemical analysis for the parameters listed in Condition
    2,
    except that sediment samples need not be analyzed for
    total
    suspended solids.
    The results
    of
    the analyses
    shall be attached to Ainerock’s
    DMRs
    and submitted to the
    Agency.
    5.
    Amerock shall continue to conduct a biological survey of
    North Kent Creek to monitor any impact of its discharges
    on the biological organisms in the stream.
    These surveys
    shall
    be
    conducted
    twice
    a year
    at
    similar
    sampling
    locations
    to
    those
    for
    chemical
    analysis
    listed
    in
    Condition
    4.
    The results
    of
    these
    surveys
    shall
    be
    submitted to the Agency’s Compliance Assurance Section,
    Water Pollution Control Division,
    2200 Churchill Road,
    P.O. Box 19276, Springfield, Illinois 62794—9276.
    6.
    Within forty-five days of the date of this order, Amerock
    shall execute and forward to:
    Lisa Moreno
    Division of Legal Counsel
    Illinois Environmental Protection Agency
    P.O. Box 19276
    2200 Churchill Road
    Springfield, Illinois 62794—9276
    a certificate of acceptance and agreement to be bound to
    all terms and conditions of the granted variance.
    The
    45-day period shall be held in abeyance during any period
    that this matter
    is
    appealed.
    Failure to execute and
    forward
    the
    certificate
    within
    45-days
    renders
    this
    variance void.
    The form of certificate is as follows.
