This is an electrical power riser diagram for the Tolmie State Park Wastewater Lift Station Retrofit project, prepared by Cross Engineers, Inc. for the Washington State Parks and Recreation Commission. The diagram details the existing and new electrical configurations for the beach restroom and dry well power systems, specifically showing the electrical infrastructure modifications for a lift station improvement project. The document is a 100% design plan set marked for review only, located in Thurston County, and provides comprehensive electrical schematic details including power control, relay configurations, grounding, and various electrical connection notes.

The diagram illustrates the technical specifications for relocating electrical components, including power control panels, alarm systems, transformers, and electrical conduits. Key electrical notes specify requirements such as using galvanized, slip-resistant, hinged and locking electrical enclosures, installing ground wires, providing side-wall mounted LED lighting, and ensuring proper grounding and circuit protection. The document is part of a larger project aimed at improving the lift station's infrastructure and eliminating potential confined space entry risks, as indicated in the related contract opportunity description.
