• . A total affected area (permit area) of 1280 acres is outlined on the maps. The bonded <br />azea within the permit boundary comprises an azea of 683 acres, and is designated by <br />a dashed line. The estimated affected area to be utilized for CKD disposal is :506 <br />acres. Surety will be posted in increments as the quarry progresses. Areas disturbed <br />prior to July 1, 1976, are included within the permit boundary, but will not be bonded <br />until operations or reclamation dictates their re-disturbance. Pre-law areas wi:hin the <br />permit boundary that are not re-disturbed will neither be bonded or reclaimed. <br />• <br /> <br />• Present vegetation on both undisturbed and disturbed land within the permit a~~ea is <br />sparse because of the intermittent, shallow soils, and dry climate. Grass cover is <br />estimated to be at 10 to 15 percent. Both the A-Band and the E3- Band are ridge <br />formers, and vegetation is exceptionally sparse on them. Species are listed in Exhibit <br />J of the original permit application. <br />2. Closure Plan <br />Once the areas aze filled with CKD to the specified limit, then final reclamation will take <br />place which is accomplished by covering the area with 6" to 12" of soil cover / growing <br />medium and seeding according to the mix that was approved in the original permit. The <br />seed mixture broadcast rates are as follows: <br />Pubescent Wheat Grass l.5 lbs. per acre <br />Western Wheat Grass 2.5 lbs. per acre <br />Blue Gamma 0.5 lbs. per acre <br />Side Oats Gamma 0.5 lbs. per acre <br />Russian Wild Rye 0.5 lbs. per acre <br />In addition Rabbit brush and skunk brush aze shrubs that rapidly revegetate naturally and <br />are recommended to supplement the grasses. <br />Planting will in the fall or early spring, dependent on the moisture conditions. <br />These areas will have a flat, smooth, gently sloping surface to prevent ponding of water <br />from rain snow fall, and are bounded on the east by graded overburden ridges, wish 2:1 <br />side slopes. <br />Cover material will consist of a final layer of waste rock from the quarry, topped ti" to <br />12" of a growing medium, which is available from previous salvage and stockpiling <br />operations. <br />5 <br />
