4 Environmental Analysis 4.9 Hazards and Hazardous Materials d) Be located on a site that is included on a list of hazardous materials site compiled pursuant to Government Code Section 65962.5 and, as a result, would it create a significant hazard to the public or the environment, e) Result in a safety hazard or excessive noise for people residing or working in the project area, for a project located within an airport land use plan, or where such a plan has not been adopted, within 2 miles of a public airport or public use airport; fi) Impair implementation of or physically interfere with an adopted emergency plan; or g) Expose people or structures, either directly or indirectly, to a significant risk of loss, injury or death involving wildland fires. 4.9.4 Impacts Analysis IMPACT 4.9-1: Would the project create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? (Less than Significant Impact) Construction Project construction would last approximately 15 months, with activities including grading, site preparation, fencing, installation of a substation pad and electrical equipment, and construction of a gen-tie line from the Project substation to the PG&E Tesla Substation immediately to the west. The Project would not involve the routine transport, use, or disposal of hazardous materials, as defined by the Hazardous Materials Transport Uniform Safety Act. Most of the waste generated during construction would be nonhazardous and consist primarily of cardboard, wood pallets, wire, scrap metal, common trash, and wood wire spools. Most construction waste would be disposed of at a nonhazardous landfill or at a recycling facility whenever feasible. Construction materials would be handled in accordance with the California Green Building Standards Code (CCR 2019), which establishes standards for construction and demolition waste management, and recycling or salvage of a minimum of 65 percent of nonhazardous construction and demolition waste. Non-recyclable construction waste would be placed into commercial trash dumpsters located onsite. Dumpsters would be collected as needed by a commercial service and delivered to a landfill. Construction would generate an average of approximately 5 cubic yards of nonhazardous solid waste per week over the period of construction. Sanitary waste would be managed using portable toilets and hauled for offsite disposal. During construction of the Project, diesel and gasoline fuels and other hazardous materials, such as oils, solvents, hydraulic fluids, and paints commonly associated with construction equipment, may be stored onsite. These materials would be stored and handled in a manner to prevent accidental release (i.e., consistent with the hazardous materials handling best management practices (BMP) and other measures contained within the required Stormwater Pollution Prevention Plan [SWPPP]), which would require them to be stored within locked aboveground containers with secondary containment. Further discussion of BMP requirements is provided in Sections 4.7, Geology, Soils, and Paleontological Resources, and 4.10, Hydrology and Water Quality. SDS for all applicable materials present at the site would be made readily available to onsite personnel. Batteries will be delivered to the Project site in DOT-certified vehicles and in compliance with all applicable requirements of the DOT, California Highway Patrol, and California Department of Griffith Energy Storage Project 4.9-12 Tetra Tech/SCH 2022120675 Draft Environmental Impact Report August 2023
