State Ecology says clean-energy programmatic EISs aim to speed siting, flag site-specific risks

Clean-energy programmatic environmental impact statements (PEISs) completed by the Washington Department of Ecology are intended to streamline siting and permitting of large clean-energy projects while flagging impacts that require detailed, project-level study. Ecology told the House Environment & Energy Committee that three PEISs (utility-scale solar, utility-scale onshore wind and green hydrogen production and storage) were completed in June 2025 and a fourth, for sustainable aviation fuel pathways, blending and distribution, is underway.
