Electron Hydro LLC submitted a SEPA application for improvements to a 26-megawatt hydropower facility on the Puyallup River. The project includes a bladder diversion, spillway system, and fish and sediment exclusion facility. The Pierce County lead agency issued the application on August 3, 2026, with public comments due by August 24.
The project falls within the Puyallup River shoreline jurisdiction and must comply with Washington State Environmental Policy Act requirements. The revised SEPA Checklist dated September 2, 2025, accompanies the application. Pierce County will review the proposal before making a final decision.
Residents near the Puyallup River may see changes to river operations during the project. The facility's upgrades aim to improve environmental protection for fish and sediment, but no specific timeline or cost details were provided in the public record.
