RECLAMATION PLAN EXHIBIT E (CONT) 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 Colorado Crushing, Inc . on other mining operations in Huerfano County. 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, when drilled, will provide approximately 71 seeds per square foot . It is a native mixture that should restore the site to its existing vegetation conditions . The winter wheat acts as a cover crop for the grasses . If the seed is broadcast, the amount will be doubled and spread on a rough surface . The seeded areas will then be dragged or raked thoroughly to set the seed. Experience shows that on other operations the seeded area will have a heavy cover of weeds after the first year. The inclusion of winter wheat will reduce this probability. It will tend to shade the seedbed, retain snow in the winter and act as a wind break for the newly emerging grasses . The second year there are fewer weeds as the grasses start to take hold. By the third year the weeds are mostly gone and the grass has established itself so it will grow in future years . WEED CONTROL 15
