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 of Environmental Protection announces a public meeting to receive comments on the draft nutrient total maximum daily load (TMDL) report for impaired waters in the Middle St. Johns River Basin, to be adopted in Rule 62-304.505, F.A.C. on  Monday, July 17, 2017, 3:00 PM at the St. Johns River Water Management District Palatka, Florida. These TMDLs as site specific interpretations of the narrative nutrient criterion that are to be presented at the public workshop include: Lake George (WBID 2893A), St. Johns River Below Lake George (WBID 2893A5) and St. Johns River Above Ocklawaha River (WBID 2213O). The draft report for these impaired waters will be placed on the department’s TMDL website by June 16, 2017 and will be provided upon request to interested parties by mail or via email distribution. The department will accept written comments on the draft report through July 28, 2017. Written comments should 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.

New!The public is invited to an August 25th, 2017 public hearing on the Total Maximum Daily Loads (TMDLs) rules, and their allocations, for certain waters impaired for nutrients in the Middle St. Johns River Basin (62-304.505), and Charlotte Harbor Basin (62-304.805). Furthermore, in accordance with paragraph 62-302.531(2)(a), F.A.C., the nutrient TMDLs for DeLeon Spring,  Gemini Springs, Sanibel Slough West and Sanibel Slough East will constitute site specific numeric interpretations of the narrative nutrient criterion set forth in paragraph 62-302.530(90)(b), F.A.C., that will supersede the otherwise applicable numeric nutrient criteria in subsection 62-302.531(2), F.A.C., for these surface water segments. The nitrate TMDL for the DeLeon Spring and Gemini Springs will also constitute a site specific numeric interpretation of the narrative nutrient criterion set forth in paragraph 62-302.530(90)(b), F.A.C., for this water segment that is in addition to the otherwise applicable numeric nutrient criteria in subsection 62-302.531(2), F.A.C., for the water segment. Written comments should be directed to: 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 via post or email: 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.
