PacWest Silicon Smelter
PacWest Silicon (formerly known as HiTest) has proposed to build a smelter on more than 180 acres at the Washington/Idaho border in Newport, WA. If the proposal is approved, the smelter would produce up to 73,000 tons of silicon metal each year.
The Washington State Department of Ecology (DOE) is the regulatory agency responsible for the environmental review of the project under the State Environmental Policy Act (SEPA) as well as issuing environmental permits for the project. Since the project location is not located in the state of Idaho, the Idaho Department of Environmental Quality (DEQ) does not have regulatory authority over this project.
The primary concern for water quality in our watershed is the impact of acid rain. Due to the close proximity of the proposed smelter location to the Lake Pend Oreille region, emissions from the smelter could impact the ecosystem function of our local waterways over time through acid deposition.
