Public invited to comment on new permits that will reduce phosphorous in the Spokane River, allow municipal dischargers more room for growth & more time to comply

(Seattle, WA – July 18, 2013) Newly-proposed municipal wastewater discharge permits for three cities in Northern Idaho will reduce the flow of phosphorous and other pollutants into the Spokane River. Today’s action is part of a larger effort being undertaken by Idaho and Washington to protect Spokane River water quality on both sides of the border.

The proposed permits establish strict new discharge limits for total phosphorus, ammonia, and biochemical oxygen demand. These limits are necessary to ensure compliance with Idaho’s water quality criteria for nutrients and Washington’s water quality criteria for dissolved oxygen. If the treatment plants are unable to meet some of these new limits with existing equipment, the permits propose to allow the utilities 10 years to make upgrades and achieve compliance.

Theses proposed permits, EPA officials assert, will significantly reduce the amount of phosphorus each facility can discharge to the Spokane River.

According to Dan Opalski, director of EPA’s office of Water and Watersheds, the new permits strike a careful balance between economic and community development needs, and long-term water quality protection.

“These are strong, flexible permits,” said EPA’s Opalski. “They protect water quality by reducing phosphorous discharge, but also offer treatment plants the needed flexibility to serve their growing communities. The cities of Post Falls, Coeur d’Alene and Hayden deserve praise for working hard to help craft these permits and prepare their communities to meet the new requirements.”

Excessive phosphorus in rivers, lakes and streams supports algae growth, reduces the amount of dissolved oxygen in the water and generally degrades water quality. Phosphorus overloading in rivers, lakes and reservoirs can affect both recreation and the well-being of fish and other aquatic life.

Today’s action follows similar discharge permits issued by the Washington Department of Ecology in 2011. Together, these permits are expected to further reduce phosphate pollution and help restore the Spokane River.

The Clean Water Act requires that all point sources discharging pollutants into waters of the United States must obtain an National Pollution Discharge Elimination System(NPDES) permit. By point sources, EPA means discrete conveyances such as pipes or man-made ditches. Some pollutants that may threaten public health and the nation's waters are: metals, nutrients human wastes, oil and grease, and pesticides, etc.
