Document Description
The California Department of Fish and Wildlife has amended Lake and Streambed Alteration Agreement Notification No. EPIMS-NAP-43108-R3, pursuant to Section 1602 of the Fish and Game Code, to the Pacific Gas and Electric Company.
This project as amended involves a revision to the method of removing sediment from on top of the existing pipeline under the Napa River as part of decommissioning that pipeline. The originally permitted method of suction dredging to remove sediment from on top of the pipeline will be replaced with under water excavation using a Toyo pump or hand jets. Excavations to retrieve the pipeline will be vertical, and removal of the pipeline through lifting techniques will allow sediments to slough off the pipeline and excavated areas to collapse into the void as the pipeline is removed, promoting rapid and natural backfill of underwater excavation areas. Any additional backfilling to pre-existing contours will occur relatively rapidly through natural hydrogeomorphic processes.
