Notice of Proposed Rule

Department:

DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.425

Nassau River Basin TMDLs

PURPOSE:

The purpose of the proposed rule is to establish a fecal coliform Total Maximum Daily Load (TMDL), and its allocation, for Unnamed Branch, which is located in Nassau County, in northeast Florida, near the Town of Callahan and flows directly into Alligator Creek and then into Mills Creek, which discharges into the Nassau River.

SUMMARY:

The TMDL addresses the fecal coliform impairment in Unnamed Branch, which was verified as impaired due to elevated fecal coliform levels using the methodology established in Chapter 62-303, Identification of Impaired Surface Waters, Florida Administrative Code, and was included on the list of impaired waters adopted by Secretarial Order on May 3, 2006.  The TMDL was developed using the “percent reduction” method and provides the percent reduction in in-stream fecal coliform concentrations needed for the branch to meet  applicable water quality criteria for fecal coliform.
The proposed TMDL is a “phased” TMDL, as authorized in 403.067(6)(c), Florida Statutes.  A phased TMDL, which allows for phased implementation, is appropriate because there are inadequate data available to identify the specific sources of coliform loads.
