In the wake of a federal consent decree between the Environmental
Protection Agency and the Sierra Club that filed a lawsuit over Mississippi’s
TMDL program, the Mississippi Department of Environmental Quality is stepping
up efforts to identify pollutants that would affect water quality in the
Delta.
“TMDLs will have an effect on every farm in the Delta,” said
Frank Howell of the Delta Council. “There are a lot of concerns from the
agricultural community about what will happen and how farmers will be affected.”
Total Maximum Daily Loads (TMDL) refers to the amount of pollutants
that a stream or river can handle without the water quality criteria being
violated or the use of the water being impaired. According to the Clean
Water Act of 1972, states are required to monitor and report water quality
and to identify waters that do not meet standards. Water bodies not meeting
standards are then placed on a Section 303D list. Mississippi’s list
is broader and includes impaired waters and waters of concern, said Randy
Reed, chief of the water quality assessment branch of MDEQ.
“The Clean Water Act requires a plan to restore the uses to
meet the standards, or TMDL,” he said. “We have to determine the maximum
amount of a pollutant that a stream can handle and if there is a particular
pollutant that exceeds that limit, we have to determine what we can do
to help the stream no longer be impaired.”
In December 1998, the Sierra Club’s lawsuit resulted in the
EPA being responsible for analyzing all of Mississippi’s TMDLs within ten
years to determine what is needed to bring them up to standard, he said.
“There is not a regulatory program that addresses the control
of non-point source pollutants from agricultural fields,” he said. “Congress
intentionally left that voluntary. We encourage the use of and provide
funding for best management practices (BMPs) to help farmers. The only
real regulatory authority that we have is for point sources, folks that
have to have a
discharge permit.”
Most pollutants in agricultural runoff don’t have water quality
standards at this point, Reed said.
“We don’t have standards for sediment or nutrients, two of the
most significant pollutants in runoff,” he said. “But by 2003, the EPA
is requiring the state to determine nutrient criteria. If we find
pollutants from agricultural land, it’s our job to educate farmers and
work with the local district conservationists to encourage the use of BMPs.”
Chat Phillips, chairman of the Yazoo/Mississippi Delta Joint
Water Management District, chairman of the Delta Council’s water conservation
committee, and a Yazoo City farmer, said MDEQ was handed “a very difficult
task” by the courts.
“We’re all working together to assist them in finding workable
solutions in the Delta to meet the goals,” Phillips said. “They realize
that cookie cutter approaches will not work all across the state because
the geography and the non-point issues are so different. Those individualized
solutions have got to come from local leadership.”
A big concern in aquaculture is that the EPA will determine
that catfish pond effluent is a point source pollutant but “the science
isn’t there,” Phillips said.
“Typically, the only time discharge occurs is during heavy storms
and the amount of discharge compared to the large volume of rainfall is
insignificant,” he said.
The state is divided into five major drainage groups, with basin
teams formed for each one. Work begins in a new group each year on a rotating
basis with a five-step development process and a five-year repeating cycle.
The five-step basic management cycle includes planning, gathering of data,
assessment of data and TMDL, developing and implementing a basin plan.
Five stakeholder meetings were recently held in the Yazoo River
Basin Delta Region to receive public input on water quality issues, to
inform the public of pending activities and establish ongoing dialogue
with the public.
“The stakeholder meetings are part of a management approach
to come up with a basin plan to help explain the water conditions in the
Yazoo River Basin, identify problem areas and develop strategies to prioritize
and address the more important issues,” Reed said. “We’re trying to foster
community involvement in the solutions. This was not required by the Clean
Water Act or the Sierra Club lawsuit.”
