Comparison: State vs. Federal

Rules. Washington has a State Environmental Policy Act (SEPA) that is similar to the National Environmental Policy Act (NEPA). SEPA requires the preparation of an environmental impact statement (EIS) whenever a governmental action may significantly affect the quality of the environment. SEPA gives agencies the ability to condition or deny a proposal due to identified likely significant adverse impacts. Washington's EIS requirements are similar to the federal rules, although the Washington Department of Ecology (WDOE) requires that all SEPA documents be submitted in electronic format through e-mail or on computer disc. See the national section ENVIRONMENTAL IMPACT STATEMENT for more information on NEPA requirements.

Administration and enforcement. All required EISs should be submitted to the WDOE, or the appropriate lead agency (usually a local town or county board) for review and distribution.
