SEO allowable seepage rate through cross-section analyzed is obtained by multiplying allowable seepage rate of <br /> 0.03 W/daylW of liner by the height of the liner(ground surface to pit bottom). <br /> 2. Seepage analyses were performed with the Seep/W 8.02 computer program. <br /> P\24M7\133-24M7-14003\Dom\Repats\Dngn Memorandum\Table Moc Page 1 of 1 <br />
