LFR Levine-Fricke Reduction of Toxicity, Mobility, and Volume through Treatment. Toxicity, mobility, and volume of pyrolytic oil-and metals-affected soil would not be reduced by treatment in this alternative. Short-Term Effectiveness. Capping the site would likely offer moderate short-term effectiveness. Implementability. This alternative would be difficult to implement. The varied ground elevations at the Site would require significant grading and drainage design. Successfully restoring the habitat would be difficult. Cost. The total capital cost for Alternative 2 is considered relatively high. These capital costs include installing additional monitoring wells to assess groundwater quality beneath the Site and laying asphalt or constructing an engineered earthen cap. The present worth of operation and maintenance costs, including 30 years of maintenance, monitoring, and reporting, is relatively high. The total net present worth of Alternative 2 is relatively high. Regulatory Acceptance. This alternative may not be accepted by DTSC or RWQCB because it does not remove the source of contamination from the Site and would require long-term operations and maintenance of the cap and long-term monitoring of the groundwater to verify this alternative offers protection to human health and the environment. The alternative may create an unsightly alternative that would reduce the ecological value of the property. Community Acceptance. The community would not likely accept this alternative on the basis of input received to date from the public on a recently completed, neighboring, and similar project named the Westley Tire Fire Site (CIWMB, 2003). Alternative 3-Excavation of Pyrolytic Oil-and Metals-Affected Soil for Off-Site Disposal. This alternative would include excavation of ash, burned material, and pyrolytic oil-and metals-affected soil for off-site disposal. Overall Protection of Human Health and the Environment. This excavation alternative offers a relatively high degree of protection to human health and the environment at the Site by removing the source of contamination. Compliance with Federal and State Requirements. As this is an interim activity, state and federal requirements will not be used to establish a final cleanup goal for the Site at this time. The Final RAP will meet final cleanup goals established after the comprehensive RI/FS is completed. However, the interim remedial action will be consistent with other state and federal requirements. Long-Term Effectiveness and Permanence. The removal of the source material from the Site would provide maximum long-term effectiveness and permanence. Page 12 Final_RAP_Tracy_9.18.03(final).doc
