Soil amendments are not expected to be required due to the nature of the soils. However, topsoil <br />samples will be subjected to agricultural testing prior to reclamation to assess fertilizer <br />requirements. The Soil Conservation Services (SCS) will be contacted periodically throughout <br />reclamation for soil tests. SCS soil fertilizer recommendations, if any, will be followed. <br />Reclamation Measures - Material Handling <br />Site reclamation measures are illustrated in Exhibit F. The Cerise property will be reclaimed as <br />upland meadow and grazing. All mine walls will be re-graded with overburden material. If needed, <br />portions of the deposit not mined may be used to supplement the overburden. Topsoil will be <br />spread over the surface of the re-graded slopes in all areas and revegetated with the appropriate seed <br />mix. Topsoil replaced in reclaimed areas will be at a depth of approximately six inches. Scrapers <br />and a dozer will be used to place the backfilled overburden and topsoil. Reclamation costs and <br />quantities are summarized in Exhibit L. <br />Water <br />All mining will occur above groundwater level and overburden and mine materials will be inert so <br />impacts to local surface water or groundwater quality are not anticipated to occur as a result of <br />mining activities. Lafarge West, Inc. will comply with all applicable Colorado water laws and all <br />applicable Federal and State water quality laws and regulations and appropriate storm water <br />management and erosion control to protect Crystal Creek and existing riparian vegetation. <br />Wildlife <br />The Cerise property is adjacent to Crystal Creek which provides wildlife habitat to a variety of <br />species (see Exhibit H for details). While a portion of the Cerise property is within this corridor; <br />most of this portion of the property is being excluded from the permit boundary for this application. <br />A fence will separate the area within the permit boundary from the Crystal Creek corridor. <br />Therefore, the proposed mining on the Cerise property will not significantly impact wildlife within <br />the riparian corridor. <br />Revegetation <br />Following topsoil replacement, reseeding will be performed according to SCS recommended <br />practices. The following revegetation procedures are anticipated: <br />• Grass seed will typically be planted in unfrozen soil between April 151" and October 151n <br />• Grass seed will be planted with a grass drill, or where necessary, with a broadcast seeder. <br />• The proposed seed mix and application rates in pounds of pure live seed per acre are <br />described on the following pages. <br />• Weed control practices will be implemented as required. <br />The above procedures may be modified as conditions dictate. If a significant invasion of noxious <br />weeds occurs, the area will be mowed periodically for control. Weeds will be mowed before they <br />go to seed during the first growing season. Mechanical control will be used as a first priority. <br />Chemical methods will be used only if no other alternative produces acceptable results. <br />Cerise Mine <br />DRMS 112 Reclamation Permit Application <br />Page E2 of E3
