Adelanto Coyote Electrode Station Electrode Replacement Project (Notification of Lake or Streambed Alteration, No. EPIMS-SBR-59387-R6)

The Adelanto Coyote Electrode Station Electrode Replacement Project, identified by Notification No. EPIMS-SBR-59387-R6, is an initiative executed by the California Department of Fish and Wildlife for the Los Angeles Department of Water and Power. Located on Bureau of Land Management property in San Bernardino County, the project focuses on replacing six failed electrodes. The scope of work includes hand digging to remove existing electrodes, drilling six new anode wells measuring 14 inches in diameter and 230 feet in depth, installing new electrodes with concrete well seals, and routing anode cables. Additionally, the project involves upgrading the AC power supply, security systems, and monitoring and communications devices within the station and control enclosure. The project area encompasses 260.16 acres, with the majority of aquatic resources being avoided to prevent environmental impact. However, the work will result in approximately 4.36 acres of temporary impacts to 1602 stream resources, specifically affecting 0.47 acres of riparian vegetation and an unnamed tributary to the ephemeral Coyote Lake. The project is categorized as exempt under California Code of Regulations Title 14, section 15302, and adheres to Section 1602 of the Fish and Game Code regarding Lake and Streambed Alteration Agreements. All activities will utilize pre-existing disturbed areas and designated staging zones around the Control Building to minimize further environmental disruption.
