JD -6 Mine Environmental Protection Plan 58 <br />13.2 Soil and Growth Media Stock Pile <br />When the JD -6 mine dump area was originally permitted, following construction of the mine waste rock <br />dump, no topsoil had been salvaged for use during reclamation efforts. Soil was subsequently salvaged <br />from the JD -6 stormwater catchment area. This soil, which is stockpiled for the JD -6 Mine reclamation, is <br />stored in the Mineral Joe Mine facilities area (Map 1) and has a calculated volume of 350 cubic yards. <br />13.3 Reseeding Specifications <br />The reclamation seed mix was specified by DOE for DOE uranium leasing sites. The seed mixture was <br />developed in consultation with BLM and is generally approved for use within the Slick Rock, Naturita, <br />Uravan, and Gateway, Colorado areas. Seed selection criteria were based on climate and elevation ranges <br />within these areas. Recognizing that surface soil conditions, nutrients, and available moisture can vary <br />within these areas, successful establishment of six or more of the twelve species is considered adequate. If <br />the total number of species seeded is less than that specified below, the seeding rates for the individual <br />species must be adjusted accordingly. All seed tags must be submitted to DOE for verification prior to the <br />seeding application. <br />Table 31.
