Notice of Proposed Rule

Department:

DEPARTMENT OF ENVIRONMENTAL PROTECTION

Chapter:

TOTAL MAXIMUM DAILY LOADS

Overview

RULE:

62-304.515

Kissimmee 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 and/or dissolved oxygen (DO) in the Kissimmee River Basin.  Furthermore, upon paragraph 62-302.531(2)(a), F.A.C., becoming effective, the nutrient TMDLs for Lake Holden, Lake Cypress, Lake Marian, Lake Jackson, and Lake Kissimmee, will constitute site specific numeric interpretations of the narrative nutrient criterion set forth in paragraph 62-302.530(47)(b), F.A.C., that will supersede the otherwise applicable numeric nutrient criteria in paragraph 62-302.531(2)(b) for these particular surface water segments.

SUMMARY:

These TMDLs address certain nutrient and DO impairments in the Kissimmee River Basin.  Specifically, the nutrient and/or DO TMDL rules being proposed for adoption are for Lake Jackson, Lake Cypress, Lake Holden, Lake Kissimmee, and Lake Marian.  These waterbodies were verified for nutrient impairments due to elevated chlorophyll a concentrations and due to low DO for Lake Jackson, using the methodology established in Chapter 62-303, F.A.C., Identification of Impaired Surface Waters.  The methodologies used to develop the TMDLs were model simulations using the Hydrological Simulation Program – Fortran (HSPF) model.  This rulemaking has been given an OGC case number 11-0653.
