<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 chara,cte•isti -s of the reclaimed ar , fc 'owing

<br />surface drainage is now and will remain tributary to the Roaring
<br />Fork River.,
<br />Plant operational Ovate: iil. --ome from the land oa ,r's later
<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 rtcontaminated by operation areas will be collected, settled,
<br />and skimmed for floating contamination prior to its release
<br />from the project area.

<br />As noted in the Soil Conservation Unit Mapping Descriptions, this area has an abundance of soil cover with which to
<br />accomplish reclamation of the area during and following the mining of sand and gravel. The reclamation of mined areas
<br />will bean ongoing process with soil cover being placed immediately on all mined areas not needed for operation, and
<br />revegetation being accomplished as soon thereafter as the season of the year permits and warrents. This process wil
<br />mi{imize rehandling of cover soil and should limit open, unreclaimed surface area to the plant and product storage ar(:;
<br />and the area in the immediate vicinity of the working face. It is anticipated that the total unreclaimed area inc! Lii)k,
<br />plant site and active mining, area should not exceed 12 acres at any one time.
<br />The mining plan as described will create some pit slopes which will be removed in Later mining operations. These
<br />temporary 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 />of the temporary slopes are those created on the west side of Area 1 (figure 5) and the .—' _ side of Area.
<br />2- . (figure 5). Final pit:sLopes will be left at 2.0/1.0 slope. These areas will be reclaimed by placement of
<br />full recomme -.ued depth of soil hover and revegetaced with Soil Conservation recommended grass mixtures, forties and
<br />shrubs of modcrate to high palatability. Arent / ( figure 5) contains a minimal amount of brush and small trees,
<br />As these: areas are cleared for mining,a •- tree and brush debris generated wil.l be randomly
<br />distributed on the wesr, north, and east final pit slopes to provide cover for and to encourage the propagation of
<br />wi dlife.
<br />Reclamation of the nearly flat areas in the bottom of the pit: will be accomplished by returning the land to hay land
<br />and cropland. The following table illustrates the existing and post mining characteristics of the land.

<br />As noted above, the area available to gravity irrigated cropland will increase by /G acres as a result of this project.
<br />ThI w ' -:ICe rettu -o- winter range slopes will increase byy acres. The quality of the wildlife winter range will improve
<br />as a resuit <,I - he improved P,rot,,ing conditions on the final pit slopes as opposed to the steep and poor soil conditions
<br />.:
<br />on the existin hill slope adjacent_ to highway 82. The additional irrigated cropland residue will also improve the
<br />quantity and ciu.tlity of wildlife winter tame. The Colorado Division of Wildlife has been contacted for an evaluation.'
