(1) Minimum Criteria. All surface waters of
the State shall at all places and at all times be free from:
(a) Domestic, industrial, agricultural, or
other man-induced non-thermal components of discharges which, alone or in
combination with other substances or in combination with other components of
discharges (whether thermal or non-thermal):
1. Settle to form putrescent deposits or
otherwise create a nuisance, or
2.
Float as debris, scum, oil, or other matter in such amounts as to form
nuisances, or
3. Produce color,
odor, taste, turbidity, or other conditions in such degree as to create a
nuisance, or
4. Are acutely toxic,
or
5. Are present in concentrations
which are carcinogenic, mutagenic, or teratogenic to human beings or to
significant, locally occurring, wildlife or aquatic species, unless specific
standards are established for such components in subsection
62-302.500(2)
or rule
62-302.530, F.A.C., or
6. Pose a serious danger to the public
health, safety, or welfare.
(b) Thermal components of discharges which,
alone, or in combination with other discharges or components of discharges
(whether thermal or non-thermal):
1. Produce
conditions so as to create a nuisance, or
2. Do not comply with applicable provisions
of Rule
62-302.520,
F.A.C.
(c) Silver in
concentrations above 2.3 micrograms/liter in predominently marine
waters.
(d) Lindane (g-ben-zene
hexachloride) in concentrations above 0.16 micrograms/liter in predominantly
marine waters or in concentrations above 0.95 micrograms/liter in predominantly
fresh waters.
(2) General
Criteria.
(a) The criteria of surface water
quality provided in subsection
62-302.500(2)
and Rule
62-302.530, F.A.C., shall apply
to all surface waters outside zones of mixing except:
1. Where inconsistent with the limitations of
Section 403.061(7),
F.S., or
2. Where relief from such
criteria has been granted pursuant to other applicable rules of the
Department.
(b) The
Department may establish a Technical Advisory Committee on request or on its
own initiative, to review and advise the Department about the sufficiency and
validity of data or methodologies and the need for revision of numerical
surface water quality criteria established in this rule chapter. The committee
shall be appointed by the Secretary and consist of professionals knowledgeable
about the specific criteria to be reviewed. The committee shall be chaired by a
representative of the Department and shall meet at the call of the chair. Any
findings, conclusions, or recommendations of the commmittee shall be conveyed
to the Secretary and to the chair of the Commission but shall not bind the
Department.
(c) Effluent limits may
be established for pollutants for which analytical detection limits are higher
than the established water quality criteria based upon computation of
concentrations in the receiving waters. Effluent limits will be established on
site-specific conditions in the context of a Department permit. Monitoring
reports and permit applications shall specify the detection limits and indicate
non-detectable results in such cases. Unless otherwise specified, such
non-detectable results shall be accepted as demonstrating compliance for that
pollutant as long as specified effluent limits are met.
(d) Criteria for metals in Rule 62-302.530
and paragraph
62-302.500(1)(c),
F.A.C., are measured as total recoverable metal. However, cadmium, chromium,
copper, lead, nickel, silver, and zinc may be applied as dissolved metals when,
as part of a permit application, a dissolved metals translator has been
established according to the procedures described in the document, "Guidance
for Establishing a Metals Translator, " Florida Department of Environmental
Protection, December 17, 2001.
(e)
A violation of any surface water quality criterion as set forth in this chapter
constitutes pollution. For certain pollutants, numeric criteria have been
established to protect human health from an unacceptable risk of additional
cancer caused by the consumption of water or aquatic organisms. These numeric
criteria are based on annual average flow conditions. However, this allowable
annual average does not relieve any activity from complying with subsection
62-302.500(1),
Rule
62-302.530, F.A.C., or any other
provision of water quality standards.
(f) Notwithstanding the specific numerical
criteria applicable to individual classes of water, dissolved oxygen levels
that are attributable to natural background conditions or man-induced
conditions which cannot be controlled or abated may be established as
alternative dissolved oxygen criteria for a water body or portion of a water
body. Alternative dissolved oxygen criteria may be established by the Secretary
or a Director of District Management in conjunction with the issuance of a
permit or other Department action only after public notice and opportunity for
public hearing. The determination of alternative criteria shall be based on
consideration of the factors described in subparagraphs
62-302.800(1)(a)
1.-4., and subsections
62-302.533(3)
-(4), F.A.C. Alternative criteria shall not result in a lowering of dissolved
oxygen levels in the water body, water body segment or any adjacent waters, and
shall not violate the minimum criteria specified in subsection
62-302.500(1),
F.A.C. Daily and seasonal fluctuations in dissolved oxygen levels shall be
maintained.
