f EXHIBIT R COMPLIANCE WITH RULE b 1. Grading shall be done to conform to the surrounding top- ography which is steep canyon walls and slopes of 1:1 or pore. This will also conform to the final land use of wildlife kabicac. a. Backfilling of overburden in the mined area will be accomplished with loaders, dozers and trucks. The material will be well shot shaley limestone which will compact well. The limestone overburden is non-toxic and thus leaching; or toxic material will not be present. b. Grading; will be done on a slope or 1:1 and follow the natural sauthernly sloping formation as closely as possible. The overburden will consist mainly of broken rock and will, therefore, not be susceptible to erosion or siltation of the affected lands. Areas outside the affecrad land will not be exposed to slides or other dama,,e. The resulting high walls in the area where sufficient overburden is not available for back- filling will be sloped to $ao and stabilized. c. Backfilling will be carried on continuously as part or the stripping program incorporated into the mining plan. Grading will be accomplished as soon as possible when access accross the area is no longer required. d. Thare will be no acid-forming or toxic -producing materials mined. e. All drill holes will be plugged or covered. Adits and shafts will be sealed upon completion of the underground mining. f. Backfilled and graded areas will have a slope of approximately 1:1 which will conform with the surround- ing cerrain. Remaining high walls will be sloped to $Oo and stabilized. This will also conform to the surround- ing terrain of steep, high limestone outcroppings. g. Agricultural use is not practical in this area. 2. a. Disturbance to the prevailing hydraulic balance of the affected land and of the surrounding area is not expected to occur. b. Water will not be impounded.
