Total Maximum Daily Loads Program
The public is invited to
attend a public workshop on the development of nutrient total maximum
daily loads (TMDLs) for Lake Tallavana (Gadsden County) in the
The workshop, to be held on February 12 @ 7:00 PM,
will provide an opportunity for the Department to present information on
TMDL modeling, discuss potential TMDL targets, and outline the next
see the Tallavana meeting agenda for location and details.
Written comments on the TMDL approach should be directed to: Douglas

Development Plan for
State Fiscal Year
2014-2015 and 2015-2016
is now available online.
The Department has
posted a detailed list
of the specific
aterbodies included on
development plan. The regulatory development plan for the
current state fiscal year (SFY), which runs from July 1, 2014 through
June 30, 2015, includes 38 individual waterbodies which will be
addressed through 10 TMDL rulemaking projects. The identified "business
plan date" in the table is the anticipated date of developing a DRAFT
TMDL and proposing TMDL rule language. Final adoption of the TMDL
usually occurs one or two months after proposal.
The plan also includes the tentative waterbodies identified for
development in SFY 2015-2016. While the plan is subject to change
depending on overall Department priorities and directives, it represents
the currently anticipated TMDL development work load and reflects
feedback received from stakeholders during a series of public
map showing the status
of development for each

What is a TMDL?
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
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?
(Surface Water Quality Standards - Chapter 62-302)
- Determine which waters are
impaired--that is, which ones are not meeting water
quality standards for a particular pollutant or
Waters Rule (IWR) - Chapter 62-303)
- 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)
- Develop, with extensive local
Basin Management Action Plans (BMAPs)
- 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.
Locations of the Department's Adopted TMDLs
DEP announces the availability of a
PDF that displays the location of the Departmentís Adopted TMDLs
as well as a PDF which shows
the status of development for each TMDL (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
