EPA requires permit for
nutrient enrichment

Since 2007, the U.S. Army
Corps of Engineers, in conjunction with the Idaho Department of Fish and Game,
has been adding nitrogen to Dworshak Reservoir in a pilot project designed to
add nutrients to the water. The experimental project is known as “nutrient
enrichment” for the micro-organisms at the bottom of the food chain. The end
result of the fertilization project is to increase productivity and improve the
health and size of Kokanee Salmon.
The project has been debated,
but recently met with the threat of a lawsuit. Ron Hanes of Orofino, represented
by the law firm of Bricklin and Newman (
The Environmental Protection
Agency (EPA) is now requiring the corps to seek a National Pollutant Discharge
Elimination System permit (NPDES) if they plan to continue their intended five
year project.
Rick Eichstaedt, counsel for
Hanes said, “They realize they are going to have to comply with the Clean Water
Act. It wasn’t an ambiguous requirement. If you are dumping chemicals or
pollutants into a water body, you have to have a permit,” said Eichstaedt.
Dworshak visitors have
reported blue-green algae appearing more frequently at the reservoir and have
attributed rashes to swimming at Dworshak. Likewise, some people believe disease
outbreaks in the steelhead population at the National Fish Hatchery are related
to increased nitrogen at the reservoir.
By contrast, agency officials
believe the project has helped reduce the blue-green algae blooms which may be
toxic. They feel an interruption in the program will actually increase algae
growth.
Joe Du Pont, Regional Fish
Manager for the department at
Bruce Henrickson, Public
Affairs Specialist for the corps stated, “The Walla Walla District has
periodically sought clarification from the EPA about the need for an NPDES
permit ever since we applied for the permit in 2007.” “Recently,” he went on to
say, “when the District received a Notice of Intent to sue, we again sought
clarification from the EPA about the need for a permit, but now in the context
of a possible legal action. EPA then gave us the requested clarification this
month (after the June 29, public meeting in Orofino), and that EPA clarification
was that the project does indeed require a permit at this time.”
