• i <br /> 3.3 Feasibility Study <br /> An engineering feasibility study will be prepared following the approval of this evaluation <br /> monitoring program. The study will contain a detailed description of the corrective action <br /> measures that could be taken at the landfill. This feasibility study will be prepared based <br /> on the present understanding of the plume. <br /> A range of alternatives will be considered to remediate the site. These alternatives will <br /> consider engineered containment, treatment, and disposal technologies. Several alternatives <br /> will be considered, including placing final cover on the landfill. <br /> The alternatives will be reviewed using three evaluation criteria: technical feasibility, <br /> implementability, and cost effectiveness. Technical feasibility refers to the likely <br /> reliability and effectiveness of the alternative in achieving the cleanup objectives for the <br /> site. Implementability considers such factors as the acceptability of the alternative to <br /> involved parties (for example, regulatory agencies and the community), the ability to <br /> obtain required permits and access agreements, and the availability of workers,equipment, <br /> or other special requirements necessary for the successful implementation of the <br /> alternative. The criterion of cost effectiveness considers the relative expense of each <br /> alternative, in comparison to the alternative's ability to achieve cleanup objectives. <br /> The above criteria are consistent with the nine general evaluation criteria established by <br /> the U.S. Environmental Protection Agency (EPA) for federal Superfund sites. EPA's <br /> evaluation criteria are as follows: <br /> 1. Overall protection of human health and the environment <br /> 2. Compliance with applicable or relevant and appropriate requirements <br /> 3. Long-term effectiveness and permanence <br /> 4. Reduction of toxicity, mobility, or volume <br /> 5. Short-term effectiveness <br /> 6. Implementability <br /> 7. Cost <br /> 8. Support agency acceptance <br /> 9. Community acceptance <br /> For the purposes of the study, EPA criteria numbers 1, 3, 4, and 5 are addressed under <br /> the general criterion of technical feasibility; EPA criteria numbers 2, 6, 8, and 9 are <br /> addressed under the general criterion of imlementability; and EPA criterion number 7 <br /> is addressed under the general criterion of cost effectiveness. <br /> SAC/pjM39\09390011.8a1-94/ifc:9 Rev.0, 10/17/94 <br /> 0939-001.18 <br />
