Notice of Proposed Rule

Department:

DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.625	Peace River Basin TMDLs
62-304.640	Withlacoochee River Basin TMDLs

PURPOSE:

The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for certain waters impaired for nutrients in the Peace River Basin and Withlacoochee River Basin. Furthermore, in accordance with paragraph 62-302.531(2)(a), F.A.C., the nutrient TMDLs for Lake Lulu, Lake Eloise, Lake Shipp, Lake May, Lake Howard, Lake Cannon, Lake Hartridge, Lake Idylwild, Lake Jessie, Gum Springs (Alligator Springs), Wilson Head Spring, and Blue Spring (Citrus County) will constitute site specific numeric interpretations of the narrative nutrient criterion set forth in paragraph 62-302.530(48)(b), F.A.C., that will supersede the otherwise applicable numeric nutrient criteria in subsection 62-302.531(2), F.A.C., for these surface water segments.

SUMMARY:

These TMDLs address certain nutrient impairments in the Peace River Basin and Withlacoochee River Basin. Specifically, the nutrient TMDL rules being proposed for adoption in the Peace River Basin are for Lake Lulu (WBID 1521), Lake Eloise (WBID 1521B), Lake Shipp (WBID 1521D), Lake May (WBID 1521E), Lake Howard (WBID 1521F), Lake Cannon (WBID 1521H), Lake Hartridge (WBID 1521I), Lake Idylwild (WBID 1521J), and Lake Jessie (WBID 1521K). These waterbodies were verified for nutrient impairments due to elevated chlorophyll a concentrations, using the methodology established in Chapter 62-303, F.A.C.  This rulemaking has been given an OGC case number 19-1245. 
The nutrient TMDL rules being proposed for adoption in the Withlacoochee River Basin are for Gum Springs (Alligator Springs) (1338A), Wilson Head Spring (WBID 1329R), and Blue Spring (Citrus County) (WBID 1329S). Gum Springs, Wilson Head Spring, and Blue Spring were verified for nutrient impairments because elevated concentrations of nitrate contributed to an imbalance of flora caused by algal smothering, using the methodology established in Chapter 62-303, F.A.C.  This rulemaking has been given an OGC case number 19-1246.
