• <br />EXHIBIT D <br />MINING PLAN <br />The top of the proposed mesa to be mined will be worked from the southwest to the <br />northeast by excavating with front end loaders, crushing on site and transporting off site <br />with tandem and belly-dump trucks. The top 6 to 18 inches of the mesa has been <br />identified as the limits of topsoil and will be scrapped off and stockpiled on site. The <br />topsoil stockpile will be seeded and mulched to prevent erosion until time for <br />reclamation. There is no surface or groundwater near the affected lands and no water will <br />be brought to the site for processing construction materials. Occasionally a water truck <br />may be used on site for dust suppression. <br />The proposed permitted area is 56.06 acres but the affected land area is 48 acres. A <br />minimum 20' buffer will be maintained between the permit area and the affected land <br />azea. The operation will not be phased. The entire site will be worked at one time. The <br />estimated life span of this operation is 10 years. Lambert and Associates performed five <br />soil logs and the results indicate that there may be approximately 1 million cubic yazds of <br />suitable gravel material. This report is found in Exhibit I. It is estimated that <br />approximately the top 30' of material will be removed for processing. The top 4 to 10' <br />generally consists of clayey sand to sandy clay material. The material at a depth of 4 to <br />10' to approximately 26' has been identified as sand and gravel with some cobbles. The <br />nature of the stratum immediately beneath the sand and gravel is Mancos shale. <br />The primary commodity to be mined is sand and gravel. There is no secondary <br />commodity. The sand and gravel will be used for road base, screened rock, and sand. <br />
