DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.415

Lower St. Johns River Basin TMDLs

PURPOSE:

The purpose of the rule is to adopt Total Maximum Daily Loads (TMDLs), and their allocations, for fecal coliforms, dissolved oxygen, lead, and nutrients in the Lower St. Johns River Basin.

SUMMARY:

This TMDL addresses fecal coliform, dissolved oxygen, lead, and nutrient impairments in the Lower St. Johns River Basin. Specifically, the TMDL rules being proposed for adoption are fecal coliform TMDLs for Greene Creek, Grog Branch, Julington Creek, Little Black Creek, Mill Creek, Ortega River, Peters Creek, Pottsburg Creek, and Strawberry Creek; dissolved oxygen and nutrient TMDLs for Dog Branch, Middle Trout River, Mill Creek, Ortega River, and Swimming Pen Creek; a dissolved oxygen TMDL for Sixteen Mile Creek; nutrient TMDLs for Arlington River and Doctors Lake, and lead TMDLs for Black Creek, South Fork of Black Creek, and Peters Creek. These waterbodies were verified as impaired using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The methodologies used to develop the fecal coliform TMDLs were either the percent reduction or the load duration curve methods. The nutrient targets for water segments impaired for nutrients and/or dissolved oxygen were developed using a Trophic State Index or general linear model regression methods. Nutrient TMDLs were developed using the percent reduction method. Lead TMDLs were developed using the percent reduction method. This rulemaking has been given OGC case number 09-2853.
