Total Maximum Daily Loads Highlights

Total Maximum Daily Loads Program
 

New! The Department announces the availability of draft nutrient TMDL reports, for stakeholder review and comment, for impaired lakes located in the Peace River Basin.  

The public is invited to attend a workshop on the TMDLs for Lake Bonny, Lake Hollingsworth, Lake Lena, and Deer Lake that will be held at the Southwest Florida Water Management District, Bartow Service Office, Bartow Board Room, 170 Century Boulevard, Bartow, Florida on March 26, 2014 at 1:30 p.m.  Written comments will be accepted through April 21, 2014 and should be directed to: gregory.deangelo@dep.state.fl.us

The Department announces the availability of revised draft TMDL reports for impaired waters for stakeholder review and comment in the Upper and Lower Suwannee Basins and the Santa Fe Basin.

Written comments will be accepted through April 4th, 2014 and should be directed to: Gregory.DeAngelo@dep.state.fl.us.


Everglades sceneWhat is a TMDL?

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.

The Divisions 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.

Locations of the Department's Adopted TMDLs

The DEP announces the availability of a PDF that displays the location of the Departmentís Adopted TMDLs (i.e. Final, State Rule 62-304, Florida Administrative Code F.A.C.) within the State of Florida. Please help us improve our service by providing feedback on what you think of our Adopted TMDL PDF, whether the PDF is useful, and how could we make it better. Please contact Moira Rojas (Moira.Rojas@dep.state.fl.us), (850) 245-8460 or Janis Morrow (Janis.Morrow@dep.state.fl.us), (850) 245-8543.
