Notice of Proposed Rule

Department:

DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.325

Choctawhatchee River Basin TMDLs

PURPOSE:

The purpose of the rule is to adopt new Total Maximum Daily Loads (TMDLs), and their allocations, for total nitrogen (TN) and total phosphorus (TP) that have caused low dissolved oxygen (DO) in the Choctawhatchee River Basin. This rule also renumbers certain existing TMDLs.

SUMMARY:

These new TMDLs address low DO impairments in the Choctawhatchee River Basin. Specifically, the TMDL rules being proposed for adoption are for Minnow Creek and Sikes Creek. These waterbodies were verified as impaired using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters. The TN and TP targets were set to meet a DO criterion of 5.0 mg/L. The target loads of TN and TP were modeled using the Hydrologic Simulation Program – Fortran (HSPF) model. This rulemaking has been given OGC Case Number 10-1869.
