Who is responsible for doing SEPA environmental review?
One agency is identified as the “lead agency” under the SEPA Rules WAC 197-11-924 to 938, and is responsible for conducting the environmental review for a proposal and documenting that review in the appropriate SEPA documents (DNS, DS/EIS, adoption, addendum). Two or more agencies may share lead agency status by agreement, but a single environmental analysis would be conducted and all SEPA documentation is issued jointly.
