62-302.530. Table: Surface Water Quality Criteria  


Effective on Thursday, November 17, 2016
  • 1The 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 6562-302.400(1), 66F.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 9062-302.500, 91F.A.C. The criteria contained in Rule 9762-302.500, 98F.A.C., also apply to all waters unless alternative or more stringent criteria are specified in Rule 11462-302.530, 115F.A.C. Unless otherwise stated, all criteria express the maximum not to be exceeded at any time 131except within established mixing zones or in accordance with site-specific effluent limitations developed pursuant to Rule 14762-620.620, 148F.A.C149. In some cases, there are separate or additional limits, which apply independently of the maximum not to be exceeded at any time. For example, 174the human health-based criteria that are expressed as an 183annual average (denoted as “annual avg.” in the Table) 192are applied as the maximum allowable annual average concentration at the long-term harmonic mean flow 207(see subsection 20962-302.200(2), 210F.A.C.). 211Numeric interpretations of the narrative nutrient criterion in paragraph 22062-302.530(47)(b), 221F.A.C., shall be expressed as spatial averages and 229applied over a spatial area consistent with their derivation. 238In 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.

    5043Notes5044: 5045(1) “ln H” means the natural logarithm of total hardness expressed as milligrams/L of CaCO506035061. 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 > 5081400 mg/L. (2) This criterion is protective of human health not of aquatic life. (3) For application of dissolved metals criteria see paragraph 510462-302.500(2)(d), 5105F.A.C. (4) Class III-Limited waters have at least one Site Specific Alternative Criterion as established under Rule 512262-302.800, 5123F.A.C.
