Total Maximum Daily Loads Program
News & Announcements
New! The Department announces the availability of
five draft fecal coliform Total Maximum
Daily Load (TMDL) reports for waters in the Lower St. Johns River basin
for stakeholder review and comment. The public is invited to attend a
workshop on these TMDLs that will be held in Conference Room A,
Northeast District Office, Florida Department of Environmental
Protection, 7825 Baymeadows Way, Jacksonville, FL 32256, on March 26,
2010, beginning at 9:30 AM. Written comments will be accepted through
April 12, 2010, and should be directed to:

New! The Department announces the availability of
revised TMDL reports for impaired waters in
the Tampa Bay and Hillsborough River basins. Changes in the
reports proposed in 2009 are displayed with strike-throughs and
underlines to facilitate review. Those who prefer a copy of the revised
reports without the changes being displayed may contact Mr. Jan
Mandrup-Poulsen, the section administrator for the Watershed Evaluation
and TMDL Section, at
Jan.Mandrup-Poulsen@dep.state.fl.us. Pursuant to 120.56(2)(a) F.S.,
a substantially affected person may petition for a hearing on the
proposed changes within 20 days after the date of publication of the
Notice of Change, or by Thursday Thursday,
March 11, 2010.
 What 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?
- Assess the quality of surface
waters--are they meeting water quality standards?
- Determine which waters are
impaired--that is, which ones are not meeting water
quality standards for a particular pollutant or
pollutants.
- Establish and adopt, by rule,
a TMDL for each impaired water for the pollutants of
concern--the ones causing the water quality problems.
- Develop, with extensive local
stakeholder input, a Basin Management Action Plan (BMAP)
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.
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.
