CA-EXP-0023 (Old River) Washout Repair Project (Notification of Lake or Streambed Alteration, No. EPIMS-CCA-56603-R3)

The CA-EXP-0023 (Old River) Washout Repair Project is authorized under Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-CCA-56603-R3, executed by the California Department of Fish and Wildlife for SFPP, L.P. The project is located at 7099 Orwood Road in Brentwood, Contra Costa County, California. This action is classified as a Class 2 categorical exemption under the California Code of Regulations because it replaces an existing structure on the same site with one of similar purpose and capacity. The primary objective of the project is to install a replacement section of the existing 10-inch Line Section 9 (LS-9) pipeline to address imminent exposure across the bed of Old River. Key activities include the abandonment-in-place of the existing pipeline, ground disturbance for equipment and materials staging, the excavation of trenches and entry and exit pits on both sides of the river, and the installation of the new pipeline using horizontal directional drilling methods. The project mandates that no trees be removed during these activities. Administrative oversight is provided by Torrey Soland of the Department of Fish and Wildlife and Meghan Dina of SFPP, L.P.
