We invite you to comment on the Perma-fix Northwest (PFNW) expanded scoping of a State Environmental Policy Act (SEPA) Environmental Impact Statement (EIS) during the 21-day public comment period from March 4 to March 25, 2019.
PFNW manages and treats both low-level (LLW) and mixed low-level (MLLW) radioactive wastes at its Richland facility. The treatment, storage, and handling of MLLW requires a DWR permit from Ecology. PFNW is currently seeking to renew its WR permit.
As part of the permit renewal process, PFNW submitted a renewal application for its DWR permit to Ecology in 2009. Due to significant changes and updates to the facility and operations since the original permit authorization and EIS in 1998, Ecology, as the lead agency, has determined that there is potential for adverse impacts. Therefore, we have decided to conduct a complete environmental analysis under SEPA to supplement the 1998 EIS.
