HOW THE REMEDY IS SELECTED <br /> Each alternative was assessed against the nine EPA evaluation criteria <br /> described below. Using results of this assessment, DDRW-Tracy compared <br /> the alternatives and selected a preferred alternative for the site. The nine <br /> criteria are summarized below: <br /> 1. Overall Protection of Human Health and the Environment: <br /> Addresses whether or not a remedy provides adequate protection and describes how risks <br /> posed through each pathway are eliminated, reduced or controlled through treatment, <br /> engineering controls or institutional controls. <br /> 2. Compliance with Applicable or Relevant and Appropriate Requirements(ARARs): <br /> Addresses whether or not a remedy will meet all ARARs of Federal and Stale environmental <br /> statutes and/or provide grounds for invoking a waiver. <br /> 3. Long-term Effectiveness and Permanence: <br /> Refers to the ability of a remedy to maintain reliable protection of human health and the <br /> environment over time,once cleanup goals have been met. <br /> 4. Short-term Effectiveness: <br /> Addresses the period of time needed to complete the remedy,and any adverse impact on <br /> human health and the environment that may be posed during the construction and <br /> implementation period. <br /> 5. Reduction of Toxicity,Mobility and Volume Through Treatment: <br /> Refers to the anticipated ability of a remedy to reduce the toxicity,mobility and volume of <br /> hazardous components present at the site. <br /> 6. Implementability: <br /> Refers to the technical administrative feasibility of a remedy,including the availability of <br /> materials and services needed to carry out a particular option. <br /> 7. Cost: <br /> Evaluates the estimated capital and operation and maintenance costs of each alternative. <br /> 8. State Acceptance: <br /> Indicates whether,based on its review of the information,the State concurs with,opposes <br /> or has no comment on the preferred alternatives. <br /> 9. Community Acceptance: <br /> Indicates whether community concerns are addressed by the remedy and whether or not <br /> the community has a preference for a remedy. Although public comment is an important <br /> part of the final decision,EPA is compelled by law to balance community concerns with <br /> all of the previously mentioned criteria. <br /> Source: Modified from EPA <br /> Figure 3.
