Pacific Gas and Electric Company’s Rio Dell feeder project, which will provide more reliable and increased electrical capacity, has received approval from the California State Lands Commission. … The project includes the installation of two 20-inch conduit castings under the Eel River, using Horizontal Directional Drilling. The Horizontal Directional Drilling method is a trenchless technique meant to avoid disturbance along the bore path to minimize impacts to waterways and sensitive habitats. … Permits are still needed from the California Department of Fish and Wildlife and the North Coast Regional Water Quality Control Board.
