PacWest Silicon Smelter, near Newport

EIS Scoping Public Comment Period

September 11, 2018 - October 26, 2018

PacWest Silicon is proposing to build a smelter near the city of Newport in Pend Oreille County. The manufacturing process converts quartz rock (supplied by the company HiTest Sand) into silicon metal that can be used in aluminum, silicone polymer, and polysilicon production.

Ecology has determined that this project may have significant impacts on the environment and will be conducting a full State Environmental Policy Act review of these impacts. A report called an Environmental Impact Statement (EIS) will be developed to detail the findings. As the lead agency for the environmental review, Ecology will develop the EIS to study impacts of the project on the surrounding environment. The first step in this process is to collect information from the public about what should be included in the environmental review, also called the scope.

We are looking for information about what we should study and how we should study it. 

In conjunction with the EIS scoping public comment period, there will be three public meetings and a webinar. See below for details.
