C~ <br />E.S. Comment: <br /> <br />Which waste dumps will have final slopes no steeper than a <br />horizontal to vertical ratio of 2:1? <br />Cotter Response <br />Please see Cotter response to MLRD Comment E.1. <br />E. 6. Comment: <br />Why has the operator eliminated the following items from <br />the waste dump reclamation plan: <br />a. The 6 inch clay cover which will be compacted to <br />approximately 95~ of maximum? <br />b. Approximately 4 to 6 inches of topsoil placed over <br />the top and sides of the waste dumps by the rise of <br />heavy equipment? <br />c. A diversion channel constructed immediately uF~slope <br />from the top of the waste dump? <br />Cotter Response <br />Cotter has deferred the preparation of a resF~onse <br />to MLRD Comment E.6 pending completion of a water quality <br />impact study pertinent to the waste dumps. Upon completion <br />of this study Cotter will either leave unchanged the proposed <br />language in the amendment application or revise it as appro- <br />priate. <br />E. 7. Comment: <br />How much topsoil is sufficient, in the opinion of the <br />operator, to restablish an acceptable media for plant growth? <br />Cotter Response <br />Due to the proposed seed mix, and the fact that Cotter <br />proposes to seed the surfaces on the site with slopes <br />shallower than 2(H):1(V), about six inches of topsoil will <br />be deposited and graded during reclamation. <br />-9- <br />
