ReveQetation <br />As mining operations are completed, areas for reclamation will be graded and shaped for <br />revegetation. Runoff or excess water from adjacent areas will not be allowed to flow over slopes <br />being graded and seeded. If needed, berms will be constructed to divert excess water and <br />dispose of it in a safe and non-erosive manner. <br />Upland Areas. The grass mixture below was selected to be long Lasting and regenerating. The <br />ground will be fine graded prior to seeding and fertilizers will be applied according to <br />recommendations from the Natural Resource Conservation Service. Lake side slopes below the <br />anticipated water level will not be seeded. Based on the soils in the area, the following upland <br />seed mixture is recommended: <br />Upland Grass Seed Application Area Cover <br /> Rate (%) <br /> (#PLS/acre) <br />Thicks ike Wheatgrass (Critana) 5.5 58% <br />Side-oats grama (Vaughn) 2.5 26% <br />Switchgrass (Nebr.28} 1.5 16% <br />Application rate is for drilling the seed. <br />If seed is to be broadcast, the application rate will be doubled. <br />Upland grass seed will be planted with a drill equipped with depth bands and press wheels. The <br />seeded areas will then be covered with straw mulch at a rate of 2,000 pounds per acre. The straw <br />will be crimped into the soil to control erosion until the grass becomes established. <br />If a significant invasion of noxious weeds occurs after seeding, the weeds will be mowed before <br />they can go to seed. The areas will be mowed periodically for additional control as needed. <br />Mechanical control will be used as a first priority. Chemical methods will only be used if no <br />other alternative produces acceptable results. <br />Water -General Requirement <br />To minimize the effect on the prevailing hydrologic balance, the operator shall: <br />a. comply rovith all applicable Colorado water laws, <br />b. comply with all applicable Federal and State water quality laws and regulations, <br />c. comply with alt Federal and State requirements for dredge and fill, and <br />d. regrade ali sediment and siltation structures after mining is completed. <br />15i° Avenue Si(e <br />DMG l11 Permit <br />Page 9 <br />
