New! The Division of Environmental Assessment and Restoration will present Total Maximum Daily Loads (TMDLs) rules, for certain waters impaired for nutrients in the Hillsborough River Basin on June 14th, 2019, 2:00 p.m. in Tallahassee, Florida. These TMDLs as site specific interpretations of the narrative nutrient criterion that are to be presented at the public hearing include: Lake Thonotosassa (1522B) and Flint Creek (1522A). Written comments on the TMDL should be directed to: Erin Rasnake, Program Administrator, Florida Department of Environmental Protection, MS 3555, 2600 Blair Stone Road, Tallahassee, Florida 32399-2400 or via email: Erin.Rasnake@dep.state.fl.us .
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 to reduce those 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 (F.A.C.), and the associated table of water quality criteria.
What are the basic steps in the TMDL program? How does it work?
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 (TMDL) is the heart of this comprehensive approach.
Please help us improve our service by providing feedback on what you think of our adopted TMDL document, whether it is useful, and how could we make it better. Please contact Erin Rasnake at Erin.Rasnake@dep.state.fl.us, 850-245-8338, or Janis Morrow at Janis.Morrow@dep.state.fl.us, 850-245-8543.
