Project Description Griffith Energy Storage Project <br /> Fuel, hydraulic fluids, and oils would be transferred directly to a tanker truck from the respective tanks <br /> and vessels. Storage tanks and vessels would be rinsed and transferred to tanker trucks. Other items that <br /> are not feasible to remove at the point of generation, such as lubricants, paints, and solvents, would be <br /> kept in a locked utility structure with integral secondary containment that meets applicable requirements <br /> for hazardous waste storage until removal for proper disposal and recycling. It is anticipated that all oils <br /> and batteries would be recycled at an appropriate facility. Site personnel involved in handling these <br /> materials would be trained to properly handle them. Enclosures used to store hazardous materials would <br /> be inspected regularly for any signs of failure or leakage. Transportation of the removed hazardous <br /> materials would comply with applicable regulations for transporting hazardous materials, including those <br /> set by the-U.S. Department of Transportation, U.S. Environmental Protection Agency, California <br /> Department of Toxic Substances Control, California Highway Patrol, and California State Fire Marshal. <br /> Erosion and Sediment Control and Pollution Prevention <br /> Decommissioning activities would involve exposure and disturbance of soils; therefore, measures for <br /> erosion and sediment control would be implemented in accordance with the applicable regulations in <br /> effect at that time, which are anticipated to require implementation of a SWPPP and BMPs, or similar <br /> measures. <br /> Decommissioning Water and Wastewater <br /> During decommissioning, an estimated 10,000,000 gallons of non-potable water(approximately 30.7 afj) <br /> are anticipated to be required for dust suppression and other purposes, similar to construction. Water <br /> would be trucked to the Project site from a nearby source and/or pumped from an on-site well if available, <br /> in accordance with any local, landowner provisions. <br /> Nominal liquid human waste would be generated during decommissioning. Portable restroom facilities <br /> would be provided for workers during decommissioning. <br /> Site Restoration <br /> Prior to completion of decommissioning, the Project site would be restored to its current agricultural <br /> condition. Prior to decommissioning, a Final Reclamation Plan containing details regarding site <br /> reclamation and decommissioning would be submitted by the Applicant to San Joaquin County. All roads <br /> and other areas compacted during original construction or by equipment used for decommissioning would <br /> be tilled in a manner adequate to restore the sub-grade material to the proper density and depth <br /> consistent with adjacent properties. Low areas would be filled with clean, compatible sub-grade material. <br /> After proper subgrade depth is established, locally sourced (within San Joaquin County or other location <br /> within 50 miles of the Project site)topsoil would be placed to a depth and density consistent with adjacent <br /> properties. Locally sourced compost would be applied to the topsoil, and the entire site would be tilled to <br /> further loosen the soil and blend in the compost. An appropriate seed mixture would be broadcast or <br /> drilled across the site and weed-free mulch would be applied to stabilize the soil and retain moisture for <br /> seedling germination and establishment. <br /> COMPLIANCE WITH APPLICABLE LAWS AND STANDARDS <br /> The Applicant would comply with all applicable laws and standards, including, but not limited to, those <br /> governing the use, storage, and disposal of hazardous materials; worker training and safe work practices; <br /> air quality; and water quality. Similarly, site preparation and construction activities would be performed in <br /> accordance with a SWPPP or similar plan that incorporates stormwater BMPs to reduce the adverse <br /> effects of erosion and sedimentation to on-site and downstream waterways. Herbicides would be applied <br /> by qualified personnel following product label instructions and applicable regulations. Compliance with <br /> these requirements would avoid or reduce potential adverse environmental impacts to soil, air quality, <br /> June 2022 8 Griffith Energy Storage, LLC <br />
