A no-action <br /> alternative has besn determined to be unacceptable for this site <br /> .3 <br /> based on a General" Risk Appraisal performed in accordance with the <br /> Califor.,ia LUFT Manual (1988) . Therefore, only three remediation <br /> >-- <br /> approach 4.-1 for the hydrocarbon impacted soils were considered. These <br /> included, (1) excavation of the hydrocarbon imparted soils followed <br /> �; by on-site treatment, (2) excavation of the hydrocarbon impacted <br /> soils followed by disposal to an appropriate" solid waste facility, <br /> and (3) in-situ removal of hydrocarbons from the affected area using <br /> .vapor extraction techniques. The three remediation alternatives were <br /> f evaluated according to the following criteria: <br /> 1. Level of protection of human health and the environment, <br /> including beneficial uses of ground and surface waters. <br /> 2. Reduction of toxicity, mobility and volume-of contaminants. <br /> 3. Compliance with regulatory guidelines. <br /> 4. Cost effectiveness. <br /> 5. Short term effectiveness. <br /> L•on term effectiveness. <br /> 6. - --- - -- -- -- <br /> ry Veber Point Property <br />
