TMDL/Watershed Liaison Program
TMDL/Watershed Liaison Program was created to develop TMDLs and make support easier to access for groups interested in sponsoring
TMDLs and those currently involved with a watershed project.
There are two basic and intertwined
parts to the TMDL/Watershed program:
The Intergrated Section 305(b) Water Quality Report and Section 303(d) List
of Waters Needing TMDLs
The Integrated Report.
The Clean Water Act (CWA) contains several sections which require states to
report on the quality of their waters.
Section 305(b) (State Water Quality Assessment Report)
requires a comprehensive biennial report, and Section 303(d) requires a list
of a state’s water quality-limited waters needing total maximum daily loads
(TMDLs) by April 1 of every even-numbered year. EPA suggests that states
combine these two reports into one integrated report.
What is a TMDL?
Total Maximum Daily Load (TMDL) is the
amount of a particular pollutant that a particular stream, lake, estuary or
other waterbody can "handle" without violating state water quality standards. Of
course, this is a greatly simplified explanation!
So what's the big deal?
Once a TMDL is established, responsibility for reducing pollution among both
point sources (pipes) and diffuse sources is assigned. Diffuse sources
include, but are not limited to, run-off (urban, agricultural, forestry, etc.),
leaking underground storage tanks, unconfined aquifers, septic systems, stream
channel alteration, and damage to a riparian area.
Who's responsible for
Ultimately, the state of North Dakota. However, according to the
Clean Water Act, EPA is responsible ... if the states forgo their
