Application rate is for drilling the seed. If seed is to be broadcast, the <br />application rate will be doubled. <br />**Use M corrhiza to coat the seed at time of planting for best results. <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 2,000 pounds per <br />acre. The straw will be crimped into the soil to control erosion until the grass becomes <br />established. <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 />Water -General Requirement <br />To minimize the effect on the prevailing hydrologic balance, the operator shall: <br />a. Comply with all applicable Colorado water laws. <br />b. Comply with all applicable Federal and State water quality laws and regulations. <br />c. Comply with all Federal and State requirements for dredge and fill. <br />d. Re-grade and backfill all sediment and siltation structures after mining is <br />completed. <br />Groundwater - Specific Requirements <br />The operation will not affect groundwater quality on or off the site. The operation will <br />comply with State groundwater quality standards. Due to the absence of sources of <br />potential pollutants, groundwater quality monitoring is not required in this operation. <br />The mining and reclamation will affect the groundwater table surrounding the mine site. <br />Proposed mitigation efforts to minimize these impacts are a recharge pond along the <br />southeast corner of the property to maintain groundwater levels during the mining, and <br />a perimeter drain if needed to convey groundwater around the lined reservoir after the <br />slurry wall is installed. Broken Arrow Investments, LLC proposes that the groundwater <br />elevations be monitored through both onsite and offsite wells before, during, and after <br />the mining and reclamation is complete so that impacts to the groundwater table, from <br />this mining operation, can be identified and addressed. It is the intent of Broken Arrow <br />Investments, LLC to operate responsibly and to mitigate damages to wells that are <br />directly attributable to the mining and reclamation of this site.
