<br /> " <br /> 3. The total mining proposal should develop or preserve the land so it is <br />compatible with <br /> the surrounding azea". Reclamation of the mine will return the land to its present use of <br /> grazing which matches the surrounding area. <br /> 4. The plan for extraction should consider the "quality of life" of the neazby residents. As <br />' noted in this entire application, the quality of life will be maintained in the azea by <br /> minimizing traffic congestion, visual impact, air pollution, water pollution, noise <br /> pollution, and land disturbance. <br /> 5. The extraction of the deposit should consider the master plans of the County. The <br /> Douglas County Master Plan designates this site as non-urban. With this designation, the <br /> site should be protected from intense urban development. With mining only allowed in <br /> agricultural zones, the non-urban character of the area will be preserved. <br />' 6 Th <br />l <br />ld <br />h <br />i <br />i <br />h <br />" <br />i <br />f <br />h <br />i <br />l <br />i <br />al d <br />i <br />" <br /> . e proposa <br />e commerc <br />s <br />ou <br />max <br />m <br />ze t <br />e <br />extract <br />on o <br />t <br />a <br />m <br />ner <br />epos <br />t <br />. <br /> Considering the terrain, depth of overburden, drainage patterns, and screening <br />' considerations, the mining plan maxvnizes the removal of the deposit. <br /> 7. After extraction, the land will be reclaimed according to the Colorado Mined Land <br />' Reclamation Act (C.R.S. 34-32). CMI presently holds a permit from the Colorado Mined <br /> Land Reclamation Board pursuant to this Act and a reclamation bond is in place. <br />' Based on the above criteria, it is appazent that the proposed development site contains a <br /> commercially feasible and significant mineral deposit. <br />' 3.A.2 Supply of Rhyolite Aggregate <br />Wall Mountain Tuff deposits in Douglas County are referred to as rhyolite. Douglas County <br />Rhyolite differs from normal Wall Mountain Tuff because it has a density considerably lower <br />than normal Wall Mountain Tuff and is not as glassy. It is a durable, lightweight stone whose <br />density and color varies. It is unique because it contains no calcium cazbonate and, therefore, <br />will not deteriorate because of air pollution or acid rain. It occurs in colors of light grey, dazk <br />grey, buff, brown, pink, and lavender. It is easy to shape and because of its light weight, reduces <br />' transportation and construction costs. <br />' The Douglas County Master Plan for Mineral Extraction devotes one pazagraph to Wall <br />Mountain Tuff (rhyolite) in the Stratigraphy section of the plan. Included in the Master Plan is a <br />Sand, Gravel, and Quarry Aggregate Resources map which notes the locations of volcanic and <br />' intrusive deposits. Rhyolite is the only coazse aggregate resource mined in Douglas County. <br />Most of the rhyolite deposits indicated on the Aggregate Resource map are very small in size. <br />These deposits aze very visible or adjacent to developed areas. Rhyolite deposits aze found at an <br />' elevation of approximately 6700 feet. The rhyolite is typically capped with Castle Rock <br />Conglomerate and varying depths of overburden. Trying to excavate in these areas would cause <br />excess land disturbance and is not economically feasible. <br />' 12 <br />
