2 Project Description <br /> The waste generated during decommissioning would be similar to that generated during <br /> demolition and construction: primarily non-hazardous and recycled whenever feasible. At the time <br /> of decommissioning, batteries may be considered hazardous waste in California when they are <br /> discarded, whether or not they are rechargeable. Accordingly, the battery modules included in the <br /> BESS eventually would be disposed of in accordance with the applicable hazardous waste <br /> requirements. These materials would be stored and handled in a manner to prevent accidental <br /> release. Standard construction practices would be observed such that any incidental releases <br /> would be appropriately contained and remediated as required by regulation. <br /> Many components of energy storage systems are recyclable. Numerous recyclers for the various <br /> materials to be used on the Project site operate in Colusa and other nearby counties. Metal, scrap <br /> equipment, and parts that do not have free-flowing oil can be sent for salvage. Equipment <br /> containing any free-flowing oil would be managed as waste and would require evaluation. Oil and <br /> lubricants removed from equipment would be managed as used oil, which is a hazardous waste <br /> in California. <br /> 2.5.5.1 Erosion and Sediment Control and Pollution Prevention <br /> Decommissioning activities would involve exposure and disturbance of soils; therefore, measures <br /> for erosion and sediment control would be implemented in accordance with the applicable <br /> regulations in effect at that time, which are anticipated to require implementation of a SWPPP and <br /> BMPs, or similar measures. <br /> 2.5.5.2 Decommissioning Water and Wastewater <br /> During decommissioning, an estimated 10,000,000 gallons of non-potable water (approximately <br /> 30.7 af) are anticipated to be required for dust suppression and other purposes, similar to <br /> construction. Water would be trucked to the Project site from a nearby source and/or pumped <br /> from an on-site well if available, in accordance with any local landowner provisions. <br /> Nominal liquid human waste would be generated during decommissioning. Portable restroom <br /> facilities would be provided for workers during decommissioning. <br /> 2.5.6 Compliance with Applicable Laws and Standards <br /> The Applicant would comply with all applicable laws and standards, including, but not limited to, <br /> those governing the use, storage, and disposal of hazardous materials; worker training and safe <br /> work practices; air quality, water quality, and energy storage systems more generally. Similarly, <br /> site preparation and construction activities would be performed in accordance with a SWPPP or <br /> similar plan that incorporates stormwater BMPs to reduce the adverse effects of erosion and <br /> sedimentation, and herbicide would be applied by qualified personnel following product label <br /> instructions and applicable regulations. The Project would comply with all state regulations related <br /> to protecting the quality of surface and ground waters of the state, as described in the Central <br /> Valley Regional Water Quality Control Board's January 24, 2023 letter on the Notice of <br /> Preparation for the Project. Compliance with these requirements would avoid or reduce potential <br /> adverse environmental impacts to soil, air quality, surface water and groundwater quality, human <br /> health, fire-related risk, and other environmental considerations. <br /> Griffith Energy Storage Project 2-17 Tetra Tech/SCH 2022120675 <br /> Draft Environmental Impact Report August 2023 <br />
