Petition seeks upgrades to Puget Sound sewage treatment plants

UPDATE, Feb. 12
Northwest Environmental Advocates has taken its case to court in an effort to obtain a new Washington state sewage-treatment standard under AKART — “All Known, Available and Reasonable Treatment.” For information about the case, refer to the NWEA news release and the lawsuit filed in Thurston County Superior Court.

An environmental group, Northwest Environmental Advocates, is calling on the Washington Department of Ecology and Gov. Jay Inslee to invoke a 1945 law in hopes of forcing cities and counties to improve their sewage-treatment plants.

In a petition to Ecology, the group says the state agency should require cities and counties to upgrade their plants to “tertiary treatment” before the wastewater gets discharged into Puget Sound. Such advanced treatment would remove excess nitrogen along with some toxic chemicals that create problems for sea life, according to Nina Bell, executive director of NWEA, based in Portland.

Most sewage-treatment plants in the region rely on “secondary treatment,” which removes most solids but does little to reduce nitrogen or toxic chemicals. Secondary treatment is an outdated process, Nina told me, adding that Ecology needs to lead the way to a more advanced treatment technology.

“It’s a travesty that cities around Puget Sound continue to use 100-year-old sewage-treatment technology when cities across the nation have demonstrated that solutions are available and practical,” she said.

Petition seeks to revoke Department of Ecology’s clean-water authority

Citing pollution problems in Puget Sound, an environmental group is asking the Environmental Protection Agency to revoke Washington state’s authority to enforce the federal Clean Water Act.

Northwest Environmental Advocates, based in Portland, says a review of 103 discharge permits issued by the Washington Department of Ecology shows a failure to control nitrogen pollution. Excess nitrogen reduces oxygen levels in the water and triggers algae blooms, resulting in serious problems in Puget Sound, according to a petition submitted to the EPA.

“Ecology determined that over 80 percent of the human sources of nitrogen in Puget Sound comes from cities and towns, but it continues to issue discharge permits as if it were completely ignorant of these facts,” Nina Bell, the group’s executive director, said in a news release.

“It’s just flat out illegal to issue permits that contribute to harmful pollution levels,” she added. “These permits are the walking dead, existing merely to create the impression that the state is doing its job to control water pollution when it is not.”
