These grasses have proven to do well in the dry medium elevation environment of western <br /> Colorado. They will prevent erosion and do provide forage and cover for animals. Certified weed <br /> free hay or straw mulch will also be applied at the rate of 2000 lbs/acre. The mulch will be <br /> crimped into the ground to provide soil stabilization. <br /> 6. Post-Reclamation Site Drainage <br /> The site will contain a 100-year 24 hour event. Once Mining Area 2 is removed,the unreclaimed <br /> portions of the site would again be vulnerable to erosion. For this reason,the outside edge of the <br /> perimeter of the site will have an 18-inch-high berm of approximately 6H:1 V slope left in place <br /> to ensure that no disturbed area runoff leaves the site in the final reclamation stage. <br /> This stormwater containment berm will hold back the water producing a shallow pool. This pool <br /> will quickly dissipate into the pit floor.No drainages enter the site,meaning a diversion ditch <br /> will not be needed. A small area in relation to the total mining area(the southwest portion)will <br /> be allowed to drain into the reclaimed area,but the size of the pit floor will be able to allow <br /> infiltration. Stormwater will sheet flow down the side slopes (3H:IV) across the pit floor and <br /> pool behind the stormwater berm. This berm will be left in place due to its shallow slopes and <br /> minimal height. It will be seeded and mulched at the time that the various segments on Mining <br /> Area 2 are extracted. <br /> 7. Revegetation Success Criteria <br /> Revegetation will be deemed adequate when erosion is controlled, and the vegetation cover is <br /> similar to the existing cover and is considered satisfactory according to Division standards. No <br /> shrub standard is proposed for the reclamation success criteria. <br /> 8 Monitoring Reclamation Success <br /> Monitoring the reclamation on an ongoing basis will ensure its success. The operator plans to use <br /> the local NRCS office to determine the capacity of the reclaimed land to control erosion. If <br /> minor changes or modifications are needed to the seeding and reclamation plan, revision plans <br /> will be submitted to the Division. It is hoped that the Division will provide assistance in <br /> evaluating the success of the ongoing reclamation process. Information on all areas disturbed and <br /> reclaimed as well as any other important items regarding the reclamation will be submitted in the <br />
