<br />There appears to 6e only about 1215 cubic yards of <br />topsoil that may have been salvaged from the Niwot <br />series. In the previous permit, the operator <br />stated: <br />"Dverburden from past and future mining, that lies <br />above the deposit is currently being segregated and <br />stockpiled above the quarry site. It is estimated <br />that approximately 41,000 to 50,000 yards ^f this <br />colluvial sail will be needed to plate the bottom <br />area of the quarry, stockpile and production areas. <br />There will be mare than enough of this soil to <br />complete the revegetation and restoration effort." <br />It should be pointed out that the intent was to <br />reclaim with soil taken from the uplands and not the <br />Niwot series. The operator stated in Exhibit I of <br />his original report "The Soil Conservation Service <br />has written a recommendation for the employment of <br />this soil [colluvial Land? in the lower areas of the <br />production areas." At the time, Andesite Rock Co. <br />took over the bottom land which was totally <br />disturbed and it is not known if the topsoil was <br />stockpiled er.cept for the 1215 cubic yards that <br />remain. <br />The soil survey of Houlder County Area, Colorado, <br />USDA, 5oi1 Conservation Service, 1975, suggests that <br />the depth of the colluvial Land (colluvial soil <br />mentioned in the earlier permit) mapping unit had a <br />depth of 60 inches where studied, but ranged from <br />shallow (less than 20 inches) to deep (greater than <br />40 inches) within the county. However, the survey <br />report did not address specific depths or properties <br />of this mapping unit. Haled on its varibility of <br />depth, stoniness, ter.ture, etc., the report simply <br />stated "materials too variable to be estimated." <br />This presents a problem. It would appear that in <br />the earlier application, through no fault of the <br />applicant, it was understood that an adequate soil <br />volume would be available for reclaiming the law <br />lands to cattle range (Exhibit E, original permit), <br />which was based on the soil survey report. The <br />report is somewhat mislezding as was substantiated <br />during an on site review by the USDA, Soil Conserva- <br />tion Service on June 23, 1977. The reviewer recog- <br />nized that only 6-12 inches of topsoil would be <br />available far reclamation. Therefore, in order for <br />the applicant to reclaim with "a minimum of 12", <br />soil would have to had been manufactured or hauled <br />to the site from other sources. This was not the <br />intent of the applicant, then or now. <br />
