A federal court in Missoula ruled Friday that the U.S. Forest Service is violating federal law by contaminating waterways with toxic fire retardant.
The court ruled the Forest Service can still use fire retardant for now, but the agency will be required to obtain a permit from the U.S. Environmental Protection Agency (EPA). The EPA will regulate how much retardant can be dropped into waterways while still complying with water quality standards.
Forest Service Employees for Environmental Ethics filed the lawsuit.
“It’s going to be a narrow needle that EPA has to thread when it comes to writing this permit,” Andy Stahl, executive director of Forest Service Employees for Environmental Ethics, said.
The Forest Service says it has already applied for the permit.
