Environmental projects

We conduct State Environmental Policy Act (SEPA) reviews for some proposed rule amendments, programs, toxic cleanup actions, various minor projects, and a few major projects such as energy transportation and storage proposals. We also review requests for, and issue a wide variety of permits for environmental projects.

Improving Spokane Watershed

Working with our partners to keep the Spokane River basin clean.


SEPA is a tool used by WA governments to determine potential environmental impacts from projects.
