Stevens <br /> Senior Reclamation Specialist <br /> Mined Land Reclamation Division <br /> 215 Centennial Bldg. <br /> 1313 Sherman St. <br /> Denver, CO 80203-2273 <br /> Dear Mr. Stevens: <br /> RE: Minor Revision Request. Tunnel Waste Disposal Pile <br /> Mid-Continent requests a minor revision for purposes of clarification as to maintenance <br /> procedures to be observed in placement of pond cleanings on the tunnel waste <br /> disposal pile. These include grading to allow for adequate drainage and to prevent <br /> surface depressions in the interface between the pile and the adjacent hillside. <br /> Minor Revision 8, approved March 15, 1988, approved placement of pond cleanings on <br /> the Rock Tunnel Pile. Our submission at that time did not specifically discuss the <br /> maintenance of the temporary slopes and the placement of the pond cleanings. <br /> Mid-Continent notes that in construction of the pile, there is a distinction made between <br /> the final slopes, which have been built at 2(H):1(V) and compacted, as opposed to the <br /> temporary slopes, where on-going activity makes such construction procedures <br /> impractical. The pond cleanings are placed on the top of the pile, where a level area is <br /> maintained. In this area, pond material is deposited in an incised pit. The shape of the <br /> pit is necessary to prevent uncontrolled flow of material cleaned from the pond. <br /> This Minor Revision request should be placed in the permit application at Vol. 2, <br /> Appendix II-B-3, as page 171. <br /> Yours truly, <br /> Diane Delaney <br /> Mid-Continent Res. <br />
