LC50, as defined in subsection
62-302.200(1),
F.A.C., shall not be less than 100% effluent; and
(b) For chronic whole effluent toxicity, the
IC25, as defined in subsection
62-302.200(14),
F.A.C., shall not be less than the effluent concentration allowed by the mixing
zone.
(3) Facilities with
high rate dilution permitted under paragraph
62-4.244(3)(b),
F.A.C., shall meet the following whole effluent toxicity limitations.
(a) For acute whole effluent toxicity, the
LC50, as defined in subsection
62-302.200(1),
F.A.C., shall not be less than 30% effluent; and
(b) For chronic whole effluent toxicity, the
IC25, as defined in subsection
62-302.200(14),
F.A.C., shall not be less than 10% effluent.
(4) Facilities permitted as open ocean
discharges under paragraph
62-4.244(3)(c),
F.A.C., shall meet the following whole effluent toxicity limitations.
(a) For acute whole effluent toxicity, the
LC50, as defined in subsection
62-302.200(1),
F.A.C., shall not be less than 30% effluent; and
(b) For chronic whole effluent toxicity, the
IC25, as defined in subsection
62-302.200(14),
F.A.C., shall not be less than 10% effluent.
(5) Water Treatment facilities granted a
mixing zone for demineralization concentrate in accordance with paragraph
62-4.244(3)(d),
F.A.C., shall meet the following whole effluent toxicity limitations.
(a) For small water utility businesses, as
defined in Section 403.0882(2)(b),
F.S., the acute whole effluent toxicity LC50, as defined in subsection
62-302.200(1),
F.A.C., shall not be less than 20% effluent. For demineralization concentrate
discharges other than small water utility businesses, the LC50 shall not be
less than the effluent concentration allowed by the mixing zone and shall not
be less than 20% effluent; and,
(b)
For small water utility businesses, the chronic whole effluent toxicity IC25,
as defined in subsection
62-302.200(14),
F.A.C., shall not be less than 20% effluent. For demineralization concentrate
discharges other than small water utility businesses, the IC25 shall not be
less than the effluent concentration allowed by the mixing
zone.
