    OPINION OF THE
    BOARD
    (by Mr.
    Duxnelle):
    The Pollution Control Board on September 4,
    1975 granted
    Petitioners
    a variance from Rule 203(h)
    of
    the
    Water Pollution
    Regulations
    in order to apply rotenone,
    a fish toxicant,
    to
    Round Lake.
    Petitioners had applied on August
    6,
    1975 for a
    variance to apply rotenone in order
    to remove an over abundance
    of stunted yellow bass and carp populations.
    On September 4,
    1975 the Illinois Environmental Protection Agency
    (Agency)
    filed a recomrnen&tion to grant the variance subject to certain
    conditions.
    No hearing was held on the request.
    The Board
    has approved for
    f’inal
    public
    coninient a regulatory amendment to
    Rule 203(h)
    of the Water Pollution Regulations, R75-7, which
    if
    enacted would allow the use of fish toxicants under the
    direction of the Department of Conservation.
    Round Lake is
    a 215 acre lake located in Lake County,
    Illinois.
    The Illinois Department of Conservation Fish
    Surveys
    of Round Lake, which were conducted in 1968,
    1972,
    and
    1974 indicate that the quality of fish life in Round Lake has
    deteriorated.
    Based on these studies,
    the Department of
    Conservation has recommended the complete rehabilitation of
    Round Lake through the application of rotenone.
    A fishery
    biologist from the Department of Conservation will apply the
    2.5
    emulsifiable rotenone solution during
    the second week
    of September.
    Petitioners estimate that the water temperature
    of the Lake will cause the rotenone to remain toxic for a
    period of ten to fourtt~endays.
    Petitioners will prevent
    18
    —
    583
    —2—
    Round Lake from discharging during the treatment period by
    raising the level of the dam.
    I~etitionerwill treat any
    effluent discharged over the
    dam
    with potassium permanganate
    in order to detoxify’~.the rotenone.
    Between 53.8 and 64.5
    tons of fish will, be killed
    as a result of the rotenone
    treatment.
    Peti~ionerwill remove the d~adfish by volunteers
    and will dispose of the fish at
    1~rylandfill, rendering
    plants,
    or mink farms.
    Round Lake discharges to an unnamed
    creek which flows for approximately 2.5 miles before discharging
    into Long Lake.
    Neither Round Lake nor Long Lake are utilized
    as public water su~ip1ies.
    The Board finds that the application of rotenone to Round
    Lake will result in ~n enhancement of the fishery present
    in
    Round Lake.
    For this reason the
    ~oa~d
    finds the grant of a
    variance to be warranted.
    This Opinior’ constitutes the Board’s findings of fact and
    conclusions of
    law..
    I, Christan L. Moffett,
    Clerk of the Illinois Pollution Control
    Board, hereby certify the aboV? Opinion was adopted on the 18th day
    of September, 1975 by a vote of
    3—0
