<br />Derr Pit Project <br />DRMS 112 Permit <br />Upland Areas. For disturbed upland areas, the reclamation plan includes re-vegetating <br />with appropriate seed mixes to minimize erosion and reestablish natural terrain. The <br />grass mixture below was selected to be long lasting and regenerating, as recommended <br />by the Greeley NRCS field office. The ground will be fine graded prior to seeding <br />according to recommendations from the Natural Resource Conservation Service. <br />Reservoir side slopes below the anticipated reservoir water level will not be seeded. <br />The proposed seed mix is shown in the following table. <br /> <br />Upland Grass Seed Application Rate * <br />(#PLS/acre) % in mix <br />Switchgrass (Greenville, Nebraska 28, <br />Blackwell, Pathfinder) <br />0.8 #PLS/ac 20 <br />Yellow Indiangrass (Lano, Holt, Cheyenne, <br />Oto) <br />1.0 #PLS/ac 10 <br />Sideoats Grama 1.8 #PLS/ac 20 <br />Blue Grama (Hachital, Lovington) 0.3 #PLS/ac 10 <br />Western Wheatgrass (Arriba, Bartonk, Rosana) 4.0 #PLS/ac 25 <br />Sand Dropseed 0.03 #PLS/ac 5 <br />Little Bluestem 0.7 #PLS/ac 10 <br />Totals 8.63 #PLS/ac 100 <br />*Application rate is for drilling the seed. If seed is to be broadcast, the application <br />rate will be doubled. <br /> <br />The seed mix for final reclamation as described above does not require fertilizer as <br />recommended by the local NRCS office in Greeley, Colorado. The seed mix was <br />revised slightly per the NRCS’s latest recommendations that require less seed to be <br />drilled or broadcast per acre of disturbed area. <br /> <br />Upland grass seed will be planted with a drill equipped with depth bands and press <br />wheels. The seed should be drilled in the spring in the month of April for best results. <br />The seeded areas will then be covered with straw mulch at a rate of 4,000 pounds per <br />acre. The straw will be crimped into the soil to control erosion until the grass becomes <br />established. See the attached NRCS seeding recommendations. <br /> <br />If a significant invasion of noxious weeds occurs after seeding, the weeds will be <br />mowed before they can go to seed. The areas will be mowed periodically for additional <br />control as needed. Mechanical control will be used as a first priority. Chemical methods <br />will only be used if no other alternative produces acceptable results. <br /> <br />Temporary Stockpile Areas. For temporary stockpiles, the reclamation plan includes <br />re-vegetating with appropriate seed mixes to minimize erosion and establish more <br />rapidly to stabilize the stockpiles. The grass mixture below was selected as <br />recommended by the Greeley NRCS field office. The proposed seed mix is shown in the <br />following table. <br /> <br />
