October Ore Pile Reclamation Rule 8: ERP <br />110(d) Limited Impact Permit Application <br />Nuvemco LLC October Ore Pile Reclamation <br />will prevent any uphill run-on of precipitation to the site. At the end of each day of <br />loading, the loader operator, will construct a berm from the underlying on-site soil and <br />rock to protect the exposed face and edge preventing any precipitation from washing <br />freshly exposed ore from the site. <br />6.4.20 (16) QA/QC Program <br />Ore removal and transport will be in accordance with best management practices and <br />US DOT regulations. In the event of an accident or load spillage, BMPs will be used to <br />clean up spilled materials including any hydrocarbon (gas and oil from truck) releases. <br />6.4.20 (17) Plant Growth Medium (Soils) <br />6.4.20 (17) (a) An NRCS soil survey map is provided as "Exhibit T. Soil Survey Map", <br />for the October Ore Pile area. Soils of the Bodot-Sili-Rock outcrop complex are found at <br />the site. Because these soils are very thin or non-existent at the site, Nuvemco <br />proposes to remove silty soil from a location along John Brown Canyon that has <br />excessive siltation build-up. Nuvemco anticipates BLM approval and assistance for this <br />transfer of soil. <br />During the last few days of ore removal, returning haul trucks will be loaded with the silty <br />soil from John Brown Canyon. This silt will be stockpiled on a vacated portion of the ore <br />pile area and redistributed to a uniform depth of approximately 6 inches over the <br />disturbed area prior to seeding and mulching. <br />6.4.20 (17) (b) Site specific soils investigations have not been conducted. It is known <br />that site soils are very thin because the location is a bedrock bench. <br />6.4.20 (17) (c) Table 6-1 provides characteristics for the soil mapping unit present at <br />the site (Bodot, Sili-Rock outcrop complex, 5-25% slopes, very bouldery) as well as the <br />mapping unit immediately adjacent to the site (Rock outcrop-Sedgran, 40-99% slopes, <br />very stony). <br />Site soils are known to be so thin that they will not be used as a plant growth medium. <br />The silty soils which are proposed for import from John Brown Canyon are not known to <br />have characteristics that would be problematic as a plant growth medium. <br />No soil amendments have been recommended by the Bureau of Land Management <br />which has proposed a seed mixture for reclamation. <br />53
