Total Maximum Daily Loads Highlights

Total Maximum Daily Loads (TMDL) Program
 

News & Announcements

On January 27, 2017, BASF Corporation filed with the department two lower cost regulatory alternatives (“LCRAs”) on the proposed Lake Talquin nutrient TMDL (Rule 62-304.305, F.A.C.).  On February 23, 2017, the department rejected the proposed LCRAs.  The department’s response to the proposed LCRAs are available to the public and may be obtained by contacting Erin Rasnake, Program Administrator, Water Quality Evaluation and TMDL Program, Florida Department of Environmental Protection, Mail Station #3555, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400, or via email: Erin.Rasnake@dep.state.fl.us

New! The department announces a public meeting to present and receive public comments on the draft total maximum daily load (TMDL) for the nutrient impairment of Lake Adair (WBID 2997R), in the Middle St. Johns River Basin, to be adopted in Rule 62-304.505, F.A.C . The meeting is scheduled for September 28, 2017, 3:00 p.m. at Kelly Services Conference Room, 3319 Maguire Blvd, Orlando, Florida 32803. The draft TMDL document for these impaired waters will be placed on the department’s TMDL website by August 29, 2017, and will be provided upon request to interested parties by mail or via e-mail distribution. The department will accept written comments on the draft TMDLs, as well as the establishment of these nutrient TMDLs as site specific interpretations of the narrative nutrient criteria, through October 13, 2017 (extension of review time due to impacts of Hurricane Irma). Written comments should be directed to: Ansel Bubel, Mail Station #3555, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400, email: ansel.bubel@dep.state.fl.us.

New!  The department announces a public meeting to present and receive public comments on the draft total maximum daily loads (TMDLs) for the nutrient impairment of Bear Gully Lake (WBID 3009), Lake Searcy (WBID 2986E), and Lake Alma (WBID 2986D), in the Middle St. Johns River Basin, to be adopted in Rule 62-304.505, F.A.C . The meeting is scheduled for September 29, 2017, 9:30 a.m. at the Jean Rhein Central Branch Library, 215 N. Oxford Road, Casselberry, Florida 32707. The draft TMDL document for these impaired waters will be placed on the department’s TMDL website by August 29, 2017, and will be provided upon request to interested parties by mail or via e-mail distribution. The department will accept written comments on the draft TMDLs, as well as the establishment of these nutrient TMDLs as site specific interpretations of the narrative nutrient criteria, through October 13, 2017 (extension of review time due to impacts of Hurricane Irma).

New! The Florida Department of Environmental Protection announces a public meeting to which all persons are invited. The meeting is scheduled for October 11, 2017, 1:30 p.m. at the South Florida Water Management District, 2301 McGregor Blvd., Fort Myers, Florida. This technical meeting is for interested stakeholders to discuss with the department the status of TMDL development for nutrient impaired waterbodies in the Caloosahatchee River basin. The meeting will provide an opportunity for the department to present the the approach to be used for development of TMDLs, and results from modeling scenarios completed. Written comments on the TMDL approach should be received by October 25, 2017 and can be directed to: Erin Rasnake, Program Administrator, Florida Department of Environmental Protection, MS 3555, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400.  Erin.Rasnake@dep.state.fl.us.

Everglades sceneWhat 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. Water bodies 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 for those pollutants to reduce pollutants and clean up the water body.

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....
  5. Implement the strategies and actions in the BMAP
  6. Measure the effectiveness of the BMAP, both continuously at the local level and through a formal re-evaluation every five years.
  7. Adapt--change the plan and change the actions if things aren't working
  8. 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 (TMDL) is the heart of this comprehensive approach.
