State-level permits & approvals
Large facilities (≥350 MW nameplate): Washington EFSEC (Energy Facility Site Evaluation Council) has exclusive siting jurisdiction — state agency preempts all local permitting. Projects <350 MW: county-level conditional use permit (CUP) or special use permit (SUP) in agricultural or resource-zoned land; no statewide preemption floor for smaller projects. SEPA (State Environmental Policy Act): environmental review required for utility-scale projects; DNS, MDNS, or full EIS depending on county SEPA lead agency threshold. Growth Management Act (GMA): 29 WA counties must incorporate energy siting in comprehensive plans; some have adopted renewable energy elements. Shoreline Management Act (SMA): projects near shorelines require Shoreline Substantial Development Permit. Critical Areas Ordinances (CAO): wetlands, fish/wildlife habitat, flood zones, and geologically hazardous areas require county CAO compliance review. Agricultural land: county-specific farmland protection policies apply; prime farmland conversion may require additional findings under county comprehensive plan.
