RECLAMATION PLAN EXHIBIT E(CONT) SEEDBED PREPARATION When mining on an area is complete, reclamation will begin. Prior to spreading the topsoil any compacted areas will be ripped and scarified to created a deeper root zone under the resoiled areas . Once this is complete, the stockpiled soils will be spread, smoothed of large clods, worked until moderately fine. On the areas where seed is broadcast the surface will be left fairly rough to trap the seed and keep it from being affected by wind. This technique is used on other facilities in the state that are similar to this site. It works very well as reclamation has been successful. SEEDING TIME The grass seed mixture will be planted from early fall thru mid-spring (November 1 to April 30) . The time of planting will be controlled by when the resoiled areas are ready for planting. If fall planting is convenient, the seeding will be done before the first freeze (about the time Winterwheat is planted) . If spring planting is called for, it will be done in March or April weather permitting after the last frost . Both periods assure there will be adequate residual ground moisture available for the newly planted seeds . GRASSES The following seed mix was developed by the NRCS office in Walsenburg, Colorado to be used by Walsenburg Sand and Gravel, CO. on their mining operations . This mix was approved for use on the existing permit and is used at our mines in the County and has proven to be very reliable. Non-Irrigated grass seed recommendation Seed Rate PLS/acre Western Wheatgrass (Arriba) 10 . 0 Sideoats grama (Vaughn) 6. 5 Blue Grama (Lovington) 0 . 5 Winter Wheat 25 . 0 42 . 0 Using this mixture will provide approximately 71 seeds per square foot . It is a native mixture that should restore the site to its existing use. The winter wheat acts as a cover crop for W5G- Hribar Pit Amendment December 2020 16
