Total Maximum Daily Loads (TMDL) Program

News and Announcements

The Florida Department of Environmental Protection announces a public meeting beginning at on Aug. 12, 2022 2:00 PM - 3:00 PM EDT, to receive comments on the draft copper Total Maximum Daily Load (TMDL) reports for impaired waters in the Everglades West Coast Basin, to be adopted in Rule 62-304.810, Florida Administrative Code. The TMDLs that are to be presented at the public workshop include Haldeman Creek (WBID 3278R1), Rock Creek (WBID 3278R3), Naples Bay (WBID 3278R4) and Clam Bay (WBID 3278Q1) in the Everglades West Coast Basin. DEP requests that all comments be received by August 26, 2022. Comments on the TMDL approach should be submitted by email to Ansel Bubel.


New! The department announces a public meeting on Aug. 31, 2022 at 2 p.m. EDT via webinar to present and receive public comments on the draft total maximum daily loads (TMDLs) for the nutrient impairments of Lake Fran (WBID 3169G3), Lake Kozart (WBID 3169G4), Lake Richmond (WBID 3169G6), Lake Walker (WBID 3169G5), and Lake Bumby (WBID 3168W7) in the Kissimmee River Basin, to be adopted in Rule 62-304.515, F.A.C., and of Lake Davis (WBID 3168Y4), Lake Wade (WBID 3168W3), and Lake Weldona (WBID 3168Y8) in the Middle St. Johns River Basin, to be adopted in Rule 62-304.505, F.A.C. The department will accept written comments on the draft TMDLs through September 9, 2022. Written comments should be directed to: Ansel Bubel, Mail Station #3555, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400 or by email to Ansel Bubel.

What is a TMDL? 

A TMDL is a scientific determination of the maximum amount of a given pollutant that a surface water can absorb and still meet the water quality standards that protect human health and aquatic life. Waterbodies that do not meet water quality standards are identified as "impaired" for the particular pollutants of concern - nutrients, bacteria, mercury, etc. - and TMDLs must be developed, adopted and implemented to reduce those pollutants and clean up the waterbody.

The threshold limits on pollutants in surface waters - Florida's surface water quality standards on which TMDLs are based - are set forth primarily in rule 62-302, Florida Administrative Code, and the associated table of water quality criteria.


What are the basic steps in the TMDL program? How does it work?

  1. Assess the quality of surface waters-are they meeting water quality standards? (Surface Water Quality Standards - Chapter 62-302).
  2. Determine which waters are impaired-that is, which ones are not meeting water quality standards for a particular pollutant or pollutants. (Impaired Waters Rule (IWR) - Chapter 62-303).
  3. Establish and adopt, by rule, a TMDL for each impaired water for the pollutants of concern-the ones causing the water quality problems. (TMDLs - Chapter 62-304).
  4. Develop, with extensive local stakeholder input, Basin Management Action Plans (BMAPs) that:
  • Implement the strategies and actions in the BMAP.
  • Measure the effectiveness of the BMAP, both continuously at the local level and through a formal re-evaluation every five years.
  • Adapt-change the plan and change the actions if things aren't working.
  • Reassess the quality of surface waters continuously.

We are working on a more comprehensive approach to protecting Florida water quality involving basin-wide assessments and the application of a full range of regulatory and non-regulatory strategies to reduce pollution. The Total Maximum Daily Load is the heart of this comprehensive approach.
