Mineral Joe Mine Environmental Protection Plan 48 <br />13.2 Soil and Growth Media Stock Pile <br />The topsoil stockpiled for the Mineral Joe Mine reclamation is stored in mine facilities area (Map 1) and <br />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 U.S. Bureau of Land Management and is generally approved for use within <br />the Slick Rock, Naturita, Uravan, and Gateway, Colorado areas. Seed selection criteria were based on <br />climate and elevation ranges within these areas. Recognizing that surface soil conditions, nutrients, and <br />available moisture can vary within these areas, successful establishment of six or more of the twelve <br />species is considered adequate. If the total number of species seeded is less than that specified below, the <br />seeding rates for the individual species must be adjusted accordingly. All seed tags must be submitted to <br />DOE for verification prior to the seeding application. <br />Table 25.

If seed is drilled, use one -half the broadcast rate. <br />• Seeding shall be performed during one of the following time periods: <br />o For best results, between October 15 and consistent ground freeze; or <br />o Between August 1 and August 31. <br />• Revegetation efforts on the disturbed areas will be considered satisfactory when: <br />o Soil erosion resulting from the operation has been stabilized; and <br />Whetstone Associates • <br />
