• <br />over time together with the rate of deposition on each dump <br />site and the size gradations of ore sorter reject. What <br />percent of the total waste dump volume is ore sorter zeject <br />for the east dump and the west dump. <br />Cotter Response <br />A complete description of the sources and uranium content <br />of rock transported to the waste dump will be provided in the <br />revised amendment application. <br />E.1. Comment <br />"Beginning in the summer of 1983, and during the reclama- <br />tion phase, the residual waste rock will be graded, so that the <br />waste dump assumes a cross-sectional profile with a sl~~pe of <br />approximately 2(H):1(V)". Which waste dump is the operator <br />referring to? <br />Cotter Response <br />The second paragraph on page E-1 has been revised to <br />indicate that by <br />both waste dumps <br />Beginning in the <br />one-third of the <br />rock. All waste <br />time until the e <br />the time reclamation activities are completed, <br />will be graded to a side slope of 2(H):1(V). <br />summer of 1983, Cotter will remove they south <br />east waste dump to prevent sloughing of waste <br />rock deposited in the dumps from the Fresent <br />id of the mine life will be graded to a final <br />slope of 2(H):1(V). Regrading of the existing waste dumps <br />will be undertaken at the end of the mine life to insure that <br />I all waste dump slopes have a reclaimed slope of 2(H):1(V). <br />E.2. Comment: <br />Why has the operator not considered reducing the amount of <br />waste rock placed in surface dumps by incorporating and=_rground <br />disposal into the plan? <br />-7- <br />
