Brad Palmer of Lake County Road and Bridge <br />and Lake County Commissioner Kenneth Olsen were present during the inspection. <br />The mine site is located 1 34 miles southwest of Leadville on Airport Road. A 112 Conversion <br />Application (CN-O1) was approved on April 28, 2000 that increased the permit area from 8 <br />acres to 55.97 acres. The material mined from this pit is used as road base material for Lake <br />County roads. Amine sign was posted at the mine entrance with the required information. <br />Permit boundary markers delineating the permit area were noted. <br />Mining is progressing to the north into the hillside. The operator is mining the pit elopes <br />at 3h:ly. Mining is complete on the northwest corner of the site, and has been graded. The <br />operator stated that this area will be reclaimed next spring. <br />The 112 permit requires a topsoil replacement depth of 6". Very little topsoil has been <br />salvaged to date. Two small piles were noted above the pit area. According to the soils <br />information in the file, approximately 8" can be salvaged and used for reclamation. The <br />operator will need to salvage all available topsoil on site and store the material in <br />stockpiles. The stockpiles should be stored in places and configurations to minimize erosion <br />and located in areas where disturbance by ongoing mining operations. In addition, piles <br />stored in place for longer than one year must be stabilized with the planting of annual <br />and/or perennial grasses. The operator will need to ensure that all remaining topsoil is <br />salvaged in order to achieve the replacement depth of 6". If the operator plans to <br />supplement the site with other materials in lieu of topsoil, then a revision to the permit <br />reflecting this change will need to be submitted and approved by the Division. <br />A crushing and screening facility is located on site. A trailer on site stores oil, grease <br />and other lubricants. The facility is very clean, and no problems were noted. A fuel tank <br />is stored on site. A berm will need to be constructed around the tank to contain any <br />unforeseen leaks or spills. <br />I & 8 Contact Address <br /> ^ CE <br />NAME Brad Palmer ^ BL <br />OPERATOR Lake County Road & Bridge ^ FS <br />STREET PO Box 964, 1200 Hazel Street ^ HW <br />CITY/STATE/ZIP Leadville, CO 80461 ^ HMWMD (CH) <br />^ SE <br />^ WQCD (CH) <br />Cc: Carl Mount; DMG (via a-mail) <br />
