if the entire excess naturals is used as subsoil throughout the flat portion of the South pit and the <br />staging area, this would provide an additional 5' of subsoil. Another use is to reduce the cut slope <br />to a grade milder than 2H:1 V <br />Valley Fills <br />The natural drainages passing through the pit will be filled using excess fines or overburden. This <br />will require approximately 210,000 cy to fill Valley # 1 and an additional 110,000 cy for Valley #2. <br />A letter has been obtained from the COE in Durango stating that these valleys do not contain any <br />wetlands or jurisdictional waters of the United States. See letter in Appendix B. Only reject fines <br />or overburden will b~ used to provide a homogeneous fill for stability reasons. Fill will be spread <br />in 12" lifts along the bottom of the drainage. Using shallow lifts, a 90% maximum dry density <br />will be achieved and is specified for this till. The spreading will be done with a ll-8 llozer equiv- <br />alent or larger. To prevent sediment from lea~ring the permit area during construction of the valley <br />fill, and prior to the installation of the storm water channel, an isolation berm will be constructed <br />at the mouth of the drainage as seen in Map C-Z. After the valley has been filled, the area will be <br />topsoiled in a similar fashion as the Staging Area. This will be further discussed in the Reclama- <br />tion Plan. <br />7. Water Information. Rights and Augmentation <br />All water rights issues such as availability of water for this operation, consumption rates, dust con- <br />trot, etc. is presented in Exhibit G -Water Information. <br />S. Schedule of Operations <br />Mining operations will only occur as dictated by demand up to the maximum rates described ear- <br />lier in the mine plan. Mining, screening and processing will take place for 18-26 weeks intermit- <br />tently throughout the year and product will be sold from this activity throughout the year, although <br />less is sold in winter months. The operator will not have night gavel mining operations, although <br />minor truck activity or repairs may occur after hours. Mining, processing and trucking will take <br />place no more than 12 hours per day, 6 days per week. <br />Cugnitti 12!03 19 <br />
