DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

SURFACE WATER QUALITY STANDARDS

Overview

RULE:

62-302.200	Definitions
62-302.530	Table: Surface Water Quality Criteria
62-302.531	Numeric Interpretations of Narrative Nutrient Criteria
62-302.532	Estuary-Specific Numeric Interpretations of the Narrative Nutrient Criterion
62-302.800	Site Specific Alternative Criteria

PURPOSE:

The proposed rules establish numeric interpretations of the narrative surface water quality criterion for nutrients in paragraph 62-302.530(47)(b), F.A.C., for streams, lakes, spring vents, and specific estuaries in Southwest and South Florida. These interpretations, which are Florida water quality standards, are intended to fully protect the designated use of surface waters. A new type of Site Specific Alternative Criteria (Type III) is also established that is specifically tailored to address nutrients and nutrient response variables.

SUMMARY:

The Department is amending Chapter 62-302, F.A.C., to establish numeric interpretations of the narrative surface water criterion for nutrients in paragraph 62-302.530(47)(b), F.A.C. The proposed amendments establish numeric interpretations in a hierarchy, as follows: 1) site specific interpretations (e.g., Total Maximum Daily Loads (TMDL), Site Specific Alternative Criteria), 2) interpretations based on cause-and-effect relationships between nutrients and biological response, 3) reference-based interpretations within nutrient watershed regions combined with biological information, and 4) the existing narrative criterion, which will continue to apply to all waters, including those that do not fall under one of the hierarchical levels above. Numeric interpretations are established for: 1) lakes (based on color and alkalinity), 2) spring vents, and 3) streams (based on stream nutrient watershed regions). In addition, estuary specific nutrient standards are established for a number of south Florida estuaries, including Clearwater Harbor/St. Joseph Sound, Tampa Bay, Sarasota Bay, Charlotte Harbor, Tidal Cocohatchee River/Ten Thousand Islands, Florida Bay, Florida Keys, and Biscayne Bay. A new Type III Site Specific Alternative Criterion is established that is specific to nutrients and nutrient response variables. The Department has also identified a list of previously adopted TMDLs that constitute a numeric interpretation of the narrative nutrient criterion under Rule 62-302.531, F.A.C., which list may be obtained from the Department’s internet site at http://www.dep.state.fl.us/water/wqssp or by writing to the Florida Department of Environmental Protection, Standards and Assessment Section, 2600 Blair Stone Road, MS 6511, Tallahassee, FL 32399-2400.
