<br />As noted in the Soil Conservation Unit 'Lipping Descriptions, Lhis area has an abundance of soil cllvcr . :ith which to
<br />accomplish reclamation of the area during and following the mining of sand and gravel. The reclamation of mined areas
<br />will be an ongoing process with soil cover being placed immediately on all mined areas not: needed -or operation, and
<br />revegetation being accomplished as soon thereafter as the season of the year )ermits and warrent's. This }:process will
<br />j —� - - --- ininimize rehandling of cover soil and should limit open, unreclaimed surface area to the plant and product storage area
<br />- — ^a--- and the area in the immediate vicinity of the working face. It is anticipate,' that the total unre,[aimed area including,
<br />�-- `�-- plant site and active mining area should not exceed 12 acres at any one time.
<br />0 3``O \ 3so ` The mining plan as described wilt create some pir slopes which wi11 be removed in later mining operations. These
<br />emporary slopes will be cut at 1.5/1.0 or flatter to accommodate temporary reclamation by minimal soil cover and
<br />seeding of Soil conservation recommended grasses mixtures and forbes of moderate to high palatability. Examples
<br />the temporary slopes are those created on the south and west side of Area 1 (figure 5) and the south side of Area
<br />and 4 (figure 5). Final pitslopes will be left at 2.011.0 slope. These areas will be reclaimed by placement of
<br />\ tull recommended depth of soil cover and revegetat:ed with Soil Conservation recommended grass mixtures, forbes, and
<br />shrubs of moderate to high palatability. Area 4 (figure 5) contains a minimal amount of brush and smrill trees, and the
<br />t \ south side of Area 5 h:-.s a morierate coverage of low brush, pinion and juniper with some small cottonwoods and wi.11oI,
<br />It �� along; the Basin Ditch. As these areas are cleared for mining, the tree and brush debris generated will be r.andoml_v
<br />distributed on the ,,est, north, and east final piL slopes to provide cover for and to encourage the propagation of
<br />wildlife.

<br />r _ Reclamation of the nearly flat areas in the bottom of the pit-will be accomplished by returning the land to hnv land
<br />It
<br />;tnd cropland. The following table illustrates the existing and post mining characterist.ics of the land.

<br />There are no active, natural streams heading on or running across
<br />the project area. The Basin Ditch and a feeder ditch therefrom
<br />cross the project and irrigate lands within the project boundary.
<br />The mining and reclamation plans incorporate provisions for
<br />maintaining uninterupted flows in these ditches.
<br />The hydrologic characteristics of the reclaimed area following
<br />mining will be very similar to those existing today in that
<br />surface drainage is now and will remain tributary to the Roaring
<br />Fork River.
<br />Plant operational water will come from the land owner's water
<br />rights in the Basin Ditch. Operational water requirements will
<br />be minimized by maximum recirculation of wash water. Surface
<br />water percolation will be increased temporarily on the areas
<br />of active operation, but will be restored to nearly original
<br />conditions by reclamation.
<br />Any surface drainage collecting on and being potentially
<br />contaminated by operation areas will be collected, settled,
<br />and skimmed for floating contamination prior to its release
<br />from the project area.
