Ecology as SEPA Lead Agency

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.

Information provided during the SEPA review process helps agency decision-makers, applicants, and the public understand how a proposal will affect the environment.

We review proposals under SEPA on a case-by-case basis. If the scope of analysis appears different from one project to another, it is because the proposal itself raises issues that are different. SEPA review is influenced by the location and context of a specific proposal.
