~~ RECLAMATION PLAN EXHISIT E [Rules 8 Repe §8.4.5] CoNSTRUertoN MAreRIAL Ftt.e N2 M 2001-002 R[ouLAR 112 O~[RATION WEIMER ONE Q~RAVEL" January 2001 Conectlons - S Aprll 2001 [2] a.) Eventual reclamation for the entire site shall be restoration of the resulting lowered, and possibly extended, bench surface to non-irri ag ted range-land pasture, with retention of the constructed water storage and settlement ponds as farm irrigationdstock water ponds. The scant topsoil salvaged prior to excavation shall be utilized for topsoiling only the sloped areas of the pit headwalls, since topsoil is so scarce and sloped azeas aze most vulnerable to erosion and re- vegetation difficulties. Range grass re-vegetation of the finish-graded pit floor and headwall slopes at the west, south, and east boundaries of the excavation hall conclude the reclamation performed at the site. This is to resume the traditional use of the entire 43-acre site for cattle grazing as part of the Weimer Ranch. b.) Primary and traditional land use in the vicinity is dry-range livestock grazing. Some irrigated agriculture occurs in lower lands to the north. Another traditional land use in the area is mining both for surface alluvial gravels and for subsurface coal. Limited underground uranium and vanadium mining have also occurred in the region. Tate chosen rangeland grazing reclamation goal is consistent with the primary goal for other oI#en-pit mining operations, and with state and county planning goals. c.) SECTION 3.1.1 COMPLIANCE {3.1.t(t)) Post-Mining Use: Rangeland Pasture {3.13} Reclamation Phasing: 1) Headwall Slope Reduction --- ongoing, as excavation is completed and overburden is progressively stripped from mining areas 2) Overburden Disposal -- prior to each phase, either to pit floor, headwall backfill, oridepression embankment. 3) Finish-grading, reclamation ~ topsoiling, rip-loosening, reseeding, mulching -essentially all delayed ur4til closing of the mine, except jor progressively finished pit headwalls. {a.].s} Materials Handling: 1) Headwall slope-reduction: 2-horizontal 0 1-vertical finished slopes 2) Backfilled headwall slopes, and flat pit oor 3) Floors graded essentially flat, "daylighted" excavation edge toward the north.
