If seed is to be broadcast, the application rate will be <br /> doubled. <br /> Temporary Stockpile Vegetation: <br /> Luna Pubescent Wheatgrass- 15 Ib./ac <br /> Amur Intermediate Wheatgrass - 15 Ib./ac <br /> Upland grass seed will be planted with a drill equipped with depth bands and press <br /> wheels. The seeded area will then be covered with certified weed-less straw mulch at a <br /> rate of 2,000 pounds per acre. The straw will be crimped into the soil to control erosion <br /> until the grass becomes established. Drill seeding is the preferred method for <br /> revegetation. If broadcast seeding is necessary on moist soils, steep slopes, or in <br /> excessively rocky areas, success can be encouraged by broadcasting onto growth <br /> medium that is very loose. If the seed is broadcast in those circumstances, then the <br /> seeded area will be dragged to help bury the seed. <br /> Wildlife <br /> Current wildlife conditions and potential impacts are described in Exhibit H, Wildlife <br /> Information. <br /> Water- General Requirement <br /> To minimize the effect on the prevailing hydrologic balance, the operator shall: <br /> a.
