Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 156 3.9.2 Discussion a. Create a significant hazard to the public or the environment through the routine transport, use, or disposal of hazardous materials? Less than Significant Impact with Mitigation Incorporated. The Proposed Project would not require extensive or on-going use of acutely hazardous materials or substances. Proposed Project activities would require limited transport, storage, and use of equipment and materials, and routine transport of vehicles that use hazardous materials (e.g. motor oil, gasoline, diesel), as well as limited disposal of hazardous materials. In addition, contractors that handle hazardous materials are required to have a Hazardous Materials Plan that describes the hazardous materials they use, and how the materials will be properly stored, used, transported, and disposed of. All hazardous materials would be stored and used in accordance with applicable federal, state, and local regulations, and disposed of at a properly licensed disposal facility. In addition, proper spill management, including response plans and spill kits, would be implemented and maintained onsite, as is currently required by DWR. None of the Proposed Project components would generate new sources of hazardous materials. The potential for impacts due to hazards and hazardous materials will be reduced to less than significant with the incorporation of Mitigation Measures BIO-1, regarding removal of refuse, MM-HAZ 1 and BMM-HAZ 2 regarding development of a Hazardous Materials Plan and a Spill Prevention and Response Plan. MM HAZ-1: a. A Plan(s) (often a contractor’s safety plan) with a section on Hazardous Materials shall be written and kept on site that describes the hazardous materials used during project activities, and how the materials will be properly stored, used, transported, and disposed of. All hazardous materials shall be properly labeled and be recycled properly or disposed of at a properly licensed disposal facility. b. The contractor shall contact the local fire agency and the local CUPA for any site-specific requirements regarding hazardous materials or hazardous waste containment or handling. c. If hazardous materials, such as oil, batteries or paint cans, are encountered in the Impact Area, the contractor(s) shall carefully remove and dispose of them according to the Safety Plan and Spill Prevention and Response Plan. All hazardous materials will be disposed of at a properly licensed disposal facility. d. Contact of chemicals with precipitation shall be minimized by storing chemicals in watertight containers or in a storage shed (completely enclosed), with appropriate secondary containment to prevent any spillage or leakage.
