<br /> <br />File M-86-085 Adequacy Items - 2 - October 17, 1986 <br />6, Approximately how deep will the mined interval be (in feet)? <br />7. Approximately what is the anticipated time interval that the mine will <br />be active (in years)? <br />8. Bill any toxic, acid-forming, or flammable materials or chemicals be <br />used, stored, or generated on-site? If so, please list them and explain <br />how storage or containment of these materials will prevent surface and <br />ground water contamination. <br />Exhibit C - >aiap <br />1, Has the operator located all permanent man-made structures within 200 <br />freet of the affected area and the owner of each structure? If not, <br />please include these items on the map. Permanent man-made structures <br />include all houses, barns, fences, above or below ground utilities, <br />irrigation ditches, roads, bridges, wells, pipelines, reservoirs or <br />ponds, railroad tracks, cemeteries, and communication antennas. <br />2. Please include the names of all immediately adjacent surface owners of <br />record and where their lands are adjacent to yours. <br />3. Please indicate on the map locations of the topsoil, overburden and <br />salable rock stockpiles. <br />Exhibit 0 - Reclamation Plan <br />1. Pi ease describe in more detail the final grading and shaping of the <br />area. The S.C.S. recommends that "the step rock faces left after rock <br />mining should be terraced, where possible, to provide flatter areas for <br />seeding". }low will the final configuration blend in with the natural <br />topography? Please provide an approximate representative cross-section <br />showing final overall slopes (horizontal distance:vertical distance), <br />individual terrace lengths (in feet}, individual wall heights (in feet), <br />and terrace slopes (in degrees). Please describe how the operator will <br />ensure the stability of the rock face(s) after mining ceases. <br />2. Please describe the types and thickness of materials which will be <br />placed on the rock terraces and then revegetated. The S.C.S. recommends <br />that °small Qiameter rock spoil should be spread over the areas to be <br />seeded and then covered with the stockpiled topsoil materials". The <br />staff recommends that at least 1-2 feet of unconsolidated rock spoil be <br />placed on the bench surfaces in order to provide rooting depth for <br />plants and to provide a rough stable surface on which topsoil can be <br />replaced. The staff further recomonends that this rock spoil then be <br />covered with a mixture of topsoil and manure. The recommended amount of <br />applied manure is 10 tons dry weight manure per acre. Please respond <br />accordingly and include the final depth (in inches) of replaced topsoil <br />and spoil rock. <br />3. The S.C.S. recommends that "a long stemmed, weed-free, native grass hay <br />should be used to mulch the area and to protect the flatter seeded areas <br />from erosion". The staff recommends that this mulch be applied <br />immediately after seeding at a rate of 2 tons per acre, and that the <br />mulch be crimped in. Please respond. <br />
