Washington State Environmental Policy Act

Legislative History

Because SEPA was enacted over 40 years ago, none of its legislative history documents are available electronically. See the Gallagher guide on Washington State Legislative History for sources and search strategies.

For a thorough discussion of SEPA and the history of its enactment, see Dioxin/Organochlorine Center v. Pollution Control Hearings Bd.,131 Wn. 2d 345, 932 P.2d 158 (Wash. 1997).
