2 Project Description 2022). The Alameda County Fire Department would provide fire services to the portion of the gen- tle corridor in Alameda County and the PG&E Tesla Substation (Alameda County Fire Department 2022). The nearest station is located at 7000 East Avenue in the City of Livermore and is approximately 8 miles from the gen-tie corridor. Prior to operations,the Applicant would meet with the appropriate local fire departments to provide a tour of the site, including review of access points and major Project components; review the site's emergency response plan, which would include Material Safety Data Sheets as appropriate; and educate and train first responders with regard to any specific safety concerns related to the use of battery storage components and the safety systems in place. The BESS would be unmanned, and operational control, including 24/7 monitoring, would be performed off-site through the proposed SCADA system. Information that is monitored by the SCADA and associated systems include battery information such as the state of charge, battery health, current, voltage, temperature, and alarm indicators such as fire warning. If there is anomaly or issue with a battery unit, the SCADA and associated remote monitoring systems would immediately alert trained personnel. The facility has the capability to be shut down remotely, if necessary. In the rare case of a fire, operators would coordinate with first responders and fire officials to safely extinguish the fire and would follow local, state, and federal regulations to dispose of any damaged materials. The need for and manner of battery fire suppression systems will be determined by the Fire Marshall. Operational staff would also perform periodic inspections and maintenance as necessary. 2.5.4.3 Traffic and Vehicles During operation of the Project, O&M staff would visit the onsite substation periodically for switching and other operation activities. Maintenance trucks would be utilized to perform routine maintenance, including, but not limited to, equipment testing, monitoring, repair, routine procedures to ensure service continuity, and standard preventative maintenance. Routine operations would require one or two workers in a light utility truck to visit the facility on a weekly basis. Typically, one major maintenance inspection would take place annually. The expected maintenance would generate little traffic during operations. O&M vehicles would include light duty trucks (e.g., pickup, flatbed) and other light equipment for maintenance. Heavy equipment would not be utilized during normal operation. Large or heavy equipment may be brought to the facility infrequently for equipment repair or replacement or vegetation control. 2.5.5 Decommissioning The Project has an expected useful life of 35 years. It is expected to be operational in 2025 and to remain in operation through 2060. It is possible that the useful life of the Project could be extended through maintenance of existing equipment or with equipment replacement and could remain in operation beyond 2060 with further County review and approval. If operations at the site are terminated, the facility would be decommissioned. The Project site would be returned to a stable condition comparable to pre-Project conditions in accordance with applicable land use regulations in effect at that time.
