• Six inches over facilities and topsand storage areas. Revegetation The approved revegetation plan emphasizes native species planting resulting in a diverse, permanent, effective plant community capable of self-regeneration. The current seed mix is included in Section 2.05.4 of the PAP. Manure or organic mulch was spread on the topsand. The approved seed mix was drill seeded through the organic mulch. Small areas that require reseeding may be broadcast. No irrigation is proposed. The site is currently inspected at least quarterly for pests and diseases. No infestations of pests or noxious weed species have been identified. Grazing is prohibited during the first two years of vegetation establishment on reclaimed areas. Grazing may be allowed thereafter. Grazing will not be allowed to interfere with vegetation sampling for monitoring or bond release purposes, and eligible areas will not be grazed during the growing season prior to sampling. Revegetated areas that have experienced three or more growing seasons are monitored for success standards of cover and production. Eligible areas are sampled in the last two consecutive growing seasons prior to final bond release, but not earlier than years nine and ten of the extended liability period. Other Reclamation Reclamations has been completed at the site, with the exception of possible reseeding. The main facilities area has been approved for Industrial/Commercial use at the site. The two ponds (the Dugout Pond and Sediment Pond 2) and the associated ditches are approved as permanent structures. Water Rights Two wells are permitted on the site (PAP, Section 2.03.10). As discussed in Section 2.05 of the PAP, the highly permeable soil at the site precludes the ditches and ponds from holding water for a considerable period of time. Therefore, there are no water rights issues associated with surface water management at the Keenesburg Strip Mine. 7
