will likely be disturbed on a frequent basis and seeding the stockpiles may not be practical during <br /> the course of the operation. If stockpile seeding is not used, surface roughening will be <br /> maintained to limit wind and water erosion. <br /> Stockpile Grass Seed Mixture <br /> Grass Species Rate <br /> (lbs PLS/acre) <br /> Intermediate Wheatgrass 5.0 <br /> Blue Grama 1.0 <br /> Triticale (sterile hybrid) 1.25 <br /> Rates are for broadcast seeding. <br /> In order to gain an understanding of the extent of the mining operation, it is helpful to know the <br /> acres disturbed by different aspects of the mining operation. Each aspect is listed in the <br /> following table with associated disturbed area. The table illustrates a point in time where the <br /> mining disturbance could be at its maximum. At the proposed Harmony Gardens Site, it is <br /> assumed that the mining disturbance will be at its greatest during mining of the east cell. During <br /> this scenario, no reclamation will have been performed in the west cell, leaving approximately <br /> 1,500 feet of side slope for backfilling. In the worst-case scenario, as mining begins in the east <br /> cell, reclamation will begin and progress in the west cell. <br /> Mine Operation Aspects and Disturbance Areas <br /> Mining Operation Disturbed <br /> Aspect Area (acres) <br /> Active Mining Area: <br /> A 1.
