Of course, this preliminary disturbance will be within the 2-acre limited bond area. It will be <br /> used to help determine where to place trenches within the Potentially Affected Area of <br /> proposed disturbance. . . <br /> 10. Within Exhibit C, under the heading 6.3.3(1)(e)subheading 4, the Applicant discusses <br /> stockpiling waste rock/overburden proximal to the pit. Please confirm waste rock/overburden <br /> stockpiles will be placed on affected lands which have had the top 6 inches stripped. <br /> It is confirmed as depicted in various maps. All work will be performed in accordance with the <br /> proposed disturbance. <br /> 11. Within Exhibit C, under the heading 5.3.3(1)(e)subheading 4, the Applicant states <br /> highwalls will be benched and the maximum height between benches will be 4 feet. Please <br /> provide the minimum width of these benches. Please also provide a cross-sectional diagram to <br /> depict the proposal. <br /> The benching will vary as the depths of the trenches are not set and trenches will be backfilled <br /> immediately after excavation. The entire process proposed is one of exploration trenching, not <br /> mining. However, in order to conform to the requests made herein, the "benches" will be a <br /> minimum of 4 feet wide as needed. Benching will be temporary (varying daily during <br /> operations) as the trenches are backfilled once excavated and tested. An illustration of a <br /> temporary bench is attached herewith. <br /> FESSI0N41 <br /> h\J1�Ejj��pSE•N••B''G���o <br /> 1 4 <br /> J •f Q O <br /> • <br /> r T <br /> i G .•°``9yW&LES E• <br /> �0 G T FQ PROFESS <br /> 2v ��aJZc7i$ <br /> 12. In accordance with Rule 6.5(2), please provide engineering stability analyses for the <br /> proposed benched highwalls. In lieu of submitting engineering stability analyses, the Applicant <br /> may commit to maintaining a 3H:1V ratio for distance from the permit boundary to depth of <br /> excavation (i.e., an excavation of 15 feet should be no closer to the permit boundary than 45 <br /> feet). This commitment will help ensure protection of off-site lands in accordance with C.R.S. 34- <br /> 32-116(7)(h). Please note, throughout the life of mine, the Applicant may submit a Technical <br />
