• ~ • <br />gazing range, and the regional airport. Particularly steep are the slopes <br />facing south to Naturita and the San Miguel Rii er Canyon, but occasionally in <br />the north facing slope also. These slopes are compatible with safe livestock <br />gazing, with no need for traversing with farm machinery. Since the site's <br />slopes are primarily north facing they are easier to re-vegetate due to better <br />moisture retention. Mulching and intensive, managed seeding are also <br />positive factors for successful range Bass establishment. <br />8) 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 kvorked-out pit area side-slopes <br />for slope reduction, and small portions to spread evenly to level-up that floor <br />area on a very shallow drainage gadient to the northeast comer. Outfall of <br />stormwater at that corner shall be controlled Iby introduction in to the host <br />ranch irrigationstorage pond for irrigation and,' stock water. Steep headwalls <br />from completed excavation of previous operations in that portion of the site <br />shall have been previously slope-reduced, finis~t-graded, and topsoiled. <br />The north-central overburden stockpile shall also be permanently disposed of <br />in on-going highwall slope reduction, before) the completion of Secondary <br />Phase excavations. Excess overburden stripped from newly excavated areas <br />under this permit (not utilized for headwall sloe-reduction) shall be disposed <br />of in northwest depression fill disposal terrace. <br />Upon completion of the gavel extraction in the south-central (initial <br />excavation) area, west of the existing excavatx'on, the remaining mining area <br />to the north shall be stripped of topsoil and overburden. Overburden shall be <br />backfilled into the recently excavated initial exc area to reduce the steep <br />headwalls to a finished 2 to 1 grade. Excess overburden shall be placed in an <br />embankment fill within the depression in the) northwest quarter of the site. <br />Topsoil shall be added to the topsoil stockpiles at the site's west boundary. <br />After completion of all mining in the permit rea, any remaining stockpiled <br />overburden shall be placed as needed against y remaining steep headwalls <br />of the worked-out excavation to reduce backslopes. <br />(3.1.7} ~ (s.1.7} Water Considerations - Nuc1a C-C Ditch hall supply operations <br />water from Weimer Ranch rights leased to the Aerator; no Bound water <br />resources aze to be affected. <br />(3.1.7} Wildlife -not applicable, no special considerations necessary <br />{3. t.9} Topsoiling -Stockpiles of topsoil from previous pperations and all surface soils <br />stripped from excavation or disposal areas shat) be salvaged and stockpiled <br />along and inside of the south and west boundaries of the permit area.
