Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-302 - SURFACE WATER QUALITY STANDARDS › Section 62-302.530 - Table: Surface Water Quality Criteria

Current through Reg. 50, No. 138; July 16, 2024
The following table contains both numeric and narrative
				  surface water quality criteria to be applied except within zones of mixing. The
				  left-hand column of the Table is a list of constituents for which a surface
				  water criterion exists. The headings for the water quality classifications are
				  found at the top of the Table, and the classification descriptions for the
				  headings are specified in subsection
				   62-302.400(1),
				  F.A.C. Applicable criteria lie within the Table. The individual criteria should
				  be read in conjunction with other provisions in water quality standards,
				  including Rule  62-302.500, F.A.C. The criteria
				  contained in Rule  62-302.500, F.A.C., also apply
				  to all waters unless alternative or more stringent criteria are specified in
				  Rule  62-302.530, F.A.C. Unless
				  otherwise stated, all criteria express the maximum not to be exceeded at any
				  time except within established mixing zones or in accordance with site-specific
				  effluent limitations developed pursuant to Rule
				   62-620.620, F.A.C. In some
				  cases, there are separate or additional limits, which apply independently of
				  the maximum not to be exceeded at any time. For example, the criteria for
				  carcinogens, which are expressed as an annual average (denoted as "annual avg."
				  in the Table), are applied as the maximum allowable annual average
				  concentration at the long-term harmonic mean flow (see subsection
				   62-302.200(2),
				  F.A.C.). Numeric interpretations of the narrative nutrient criterion in
				  paragraph  62-302.530(47)(b),
				  F.A.C., shall be expressed as spatial averages and applied over a spatial area
				  consistent with their derivation. In applying the water quality standards, the
				  Department shall take into account the variability occurring in nature and
				  shall recognize the statistical variability inherent in sampling and testing
				  procedures. The Department's assessment methodology, set forth in Chapter
				  62-303, F.A.C., accounts for such natural and statistical variability when used
				  to assess ambient waters pursuant to sections 305(b) and 303(d) of the Federal
				  Clean Water Act.

Notes
:
(1) "ln H" means the natural
				  logarithm of total hardness expressed as milligrams/L of
				  CaCO3. For metals criteria involving equations with
				  hardness, the hardness shall be set at 25 mg/L if actual hardness is < 25
				  mg/L and set at 400 mg/L if actual hardness is > 400 mg/L. (2) This
				  criterion is protective of human health not of aquatic life. (3) For
				  application of dissolved metals criteria see paragraph
				   62-302.500(2)(d),
				  F.A.C. (4) Class III-Limited waters have at least one Site Specific Alternative
				  Criterion as established under Rule
				   62-302.800,
