0 <br /> occasionally in the north facing slope also. These slopes are <br /> compatible with safe livestock grazing, with no need for traversing <br /> with farm machinery. Since the site's slopes are primarily north facing <br /> they are easier to re-vegetate due to better moisture retention. <br /> Mulching and intensive, managed seeding are also positive factors for <br /> successful range grass establishment. <br /> 9) Before resuming mining under this 112 permit (Initial Phase),the <br /> south-central overburden stockpile from previous operations shall be <br /> transferred for permanent disposal to the west worked-out pit area, and <br /> spread evenly to level-up that floor area on a very shallow drainage <br /> gradient to the northeast comer. Outfall of stormwater at that comer <br /> shall be filtration dam controlled per the site's State-required "Storm <br /> Water Management Plan"(SWMP). Steep headwalls from completed <br /> excavation of previous operations in that portion of the site have been <br /> previously slope-reduced, finish-graded, and topsoiled. <br /> The north-central overburden stockpile shall also be permanently <br /> disposed of in an embankment fill within the depression in the <br /> northwest quarter of the site, before the completion of Secondary <br /> Phase excavations. Excess overburden stripped from newly excavated <br /> areas under this permit (not utilized for headwall slope-reduction) <br /> shall also be disposed of in that northwest depression. <br /> Upon completion of the gravel extraction in the south-central (initial <br /> excavation) area, west of the existing excavation, the remaining <br /> mining area to the north shall be stripped of topsoil and overburden. <br /> Overburden shall be backfilled into the recently excavated initial exc <br /> area to reduce the steep headwalls to a finished 2 to 1 grade. Excess <br /> overburden shall be added to the overburden stockpiles at the west end <br /> of the site. Topsoil shall be added to the topsoil stockpiles at the site's <br /> west boundary. After completion of all mining in the permit area, any <br /> remaining stockpiled overburden shall be placed as needed against any <br /> remaining steep headwalls of the worked-out excavation to reduce <br /> backslopes or bulldozed into and flattened out across the pit floor. <br /> (3.1.7) & 13.1.71 Water Considerations—Nucla C-C Ditch shall supply operations <br /> water from Weimer Ranch rights leased to the operator; no ground <br /> resources are to be affected <br /> 13.1.71 Wildlife—not applicable, no special considerations necessary <br /> 13.1.91 Topsoiling — Stockpiles of topsoil from previous operations and all surface <br /> soils stripped from excavation or disposal areas shall be salvaged and stockpiled <br /> along and inside of the south and west boundaries of the permit area. Critical area <br /> seeding shall be broadcast onto the stockpiles for interim protective vegetative cover. <br /> 16 <br />
