Liner Load and Interface Shear Data for 100 mil LLDPE. <br />Dear Mr. Keffelew: <br />The Cripple Creek & Victor Gold Mining Company ("CC&V") is attaching hereto the letter <br />report on the additional testing for the sample of 100 mil LLDPE synthetic liner material. This <br />report covers the successful liner load test (no pin holes or defects) using Drain Cover Fill and <br />Low Volume Solution Collection System Fill. Attachment A to the letter report covers this test. <br />The final results of the interface shear test using the same materials at the 4 different loadings <br />confirmed the high shear resistance. The peak and residual friction angle was 31 degrees and <br />the cohesion was 55 psf. As the report states, these results exceed the minimum interface shear <br />strength parameters of 21 degrees and 0 psf. Attachment B to the letter report contains these <br />test results. <br />appreciates the time you and your staff spent with CC&V yesterday and the long hours <br />I to review the material on the 1996 construction program. <br />Environmental Affairs <br />~4tlachment (1): Letter Report from Golder Associates dated January 26, 1996. <br />FILE: CC&VSTIP.006 <br />
