The Washington State Environmental Policy Act 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.
