Mi AGPROfessionals DIVELOPEPR , OVAGRIC.i LITRI. Exhibit D — Reclamation Plan In the event the mining operation is terminated and no soil is being removed, the following Reclamation Plan will be implemented within one year of final termination. D-1 Topsoil Segregation and Stockpiling Topsoil was not stockpiled prior to excavation for future reclamation use. Topsoil will be re- established through farming techniques such as tilling to break up the soil and introducing a soil amendment such as compost to establish a proper seed bed during the reclamation process. D-2 Reclamation Site Grading Final grading will be such that the topography is appropriate to the reclaimed use of the property, i.e. rangeland. As required, the maximum gradient will not exceed 3H: IV and final grading will achieve geotechnical stability. Ground water is not anticipated to be encountered during mining. D-3 Re-vegetation The pre-mining vegetation at the site consists of sparse native grassland. At the end of mining the disturbed areas will be re-vegetated. The re-vegetated area will be approximately 9 acres. Vegetation will be reclaimed using a native seed mixture on disturbed areas. Topsoil will be re- established through farming techniques such as tilling to break up the soil and introducing a soil amendment such as compost to establish a proper seed bed during the reclamation process. Subsoil, as exposed from construction and mining, can support good stands of grass provided adequate fertilizers are supplied and given proper protection(mulching) from erosion. Existing soil and compost material will be tilled to a depth of 6 inches to provide an adequate surface for seeding. The seedbed shall be firm and free of weeds and other non-desirable vegetation. In areas where there is excessive compaction, tillage, such as chiseling and disking, shall be done to break up the compaction then harrowed down. Dormant planting will occur anytime after October 15`h or when temperatures are cold enough to prevent seed germination. Seeding on frozen soils will be avoided. Planting may also be done in the spring until the end of April or early May and between July 1 and September 1 S`. Planting will be done with a grass drill. The recommended reclamation seeding mix provided in Table 1 was provided by the Eastern Colorado NRCS range specialist for sandy soils. Seeds will be drilled as described below or equivalent manufacturer's recommendation.
