Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement number 1600-2016-0033-R3, pursuant to Section 1602 of the Fish and Game Code to the Pacific Gas and Electric Company. The Permittee proposes pipeline an in-line inspection (I 111-D) on pipeline SP-5. This will require the excavation of an approximately 10-foot wide by 60-foot long by 12-foot deep bell hole, and an adjacent 100-foot by 50-foot work area to support an open cut construction and a drainage diversion. Staged equipment, materials and structures will include two Baker tanks/ settling basins, stockpile spoils and/or topsoil, and string and weld pipe. Low flows (<1 cfs) are expected during work activity, so sandbag cofferdams will be installed upstream and downstream of the site to isolate the work area. The work area is in a grassland floodplain area. Part of a secondary overflow channel is also within the trench impact area, and will be avoided except for where the Permittee needs to cross it to access the cofferdam. The Permittee will span a steel plate across the overflow channel to protect it where vehicles need to cross for access. Work is expected to take up to 60 days.
