Internal Review Draft (9/8/08)<br />

7 A minimum of three alternates were evaluated:<br />

Alt 2 <strong>and</strong> Alt 3 are essentially identical, at least<br />

similar. We need at least one other different<br />

alternative (e.g., SVE system). The RAP needs<br />

to justify why SVE was not included as an<br />

acceptable alternative.<br />

Response – As discussed in the response to Comment #6, SVE was not included as an<br />

acceptable alternative because it did meet the screening RAO of achieving cleanup in a<br />

timely manner. No other technically feasible/implementable cleanup technologies<br />

were identified for evaluation as a remedial alternative due to the aggressive project<br />

construction schedules. This includes various containment technologies <strong>and</strong> in situ<br />

cleanup approaches, which would not be acceptable because they would leave waste in<br />

place. The RAP will be modified to include the new text outlined previously in<br />

response to Comment #6.<br />
