SEPA - The Washington State Environmental Policy Act
The Washington State Environmental Policy Act (SEPA) provides a way to identify possible environmental impacts that may result from governmental decisions. These decisions may be related to issuing permits for private projects, constructing public facilities, or adopting regulations, policies, or plans. Information provided during the SEPA review process helps agency decision makers, applicants, and the public understand how a proposal will affect the environment. This information can be used to change a proposal to reduce likely impacts.
