1 ~ ~ R~Iv~d <br />' SfP19~ <br />' MINXING PLAN Utya~°~er~~~H <br />ke <br />B GBU~~, <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 neaz 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 be worked in five phases. The first phase consists of 13 acres and <br />' will be completed in approximately 2 to 4 years. Reclamation of the first phase will be <br />completed prior to commencing the second. The subsequent 4 phases consist of between <br />9.2 to 12.2 acres. Again, each phase will be reclaimed prior to beginning the next one. <br />' The total life span of the operation is approximately 10 to 15 yeazs depending on the <br />mazket demand. <br />' Lambert and Associates performed five soil logs and the results indicate that there may <br />be approximately 1 million cubic yazds of suitable gravel material. This report is found in <br />Exhibit I. It is estimated that approximately the top 30' of material will be removed for <br />' processing. The top 4 to 10' generally consists of clayey sand to sandy clay material. The <br />material at a depth of 4 to 10' to approximately 26' has been identified as sand and gravel <br />with some cobbles. The nature of the stratum immediately beneath the sand and gravel is <br />' 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 /> <br /> <br />t <br /> <br /> <br /> <br />
