facing slopes of shallow soils and rock outcrops. These vegetation types are common to western <br /> Colorado and Utah. <br /> Current and historical land use within the permit area is livestock grazing and wildlife habitat. <br /> Cattle are run seasonally within the rangelands and grazeable woodlands. <br /> Description of the Operation and Reclamation Plans <br /> The McClane Canyon Mine is currently a non-producing underground coal mining operation. <br /> The Division on February 15, 2011 received notification from McClane Canyon Mining, LLC <br /> that the McClane Canyon Mine would be in temporary cessation and would likely remain in that <br /> status for more than a year. <br /> The permit area encompasses 3,561.4 acres, of which approximately 1,641.7 acres have been <br /> affected by mining under the current mining plan. The area approved for surface disturbance is <br /> 14.35 acres. The on-the-ground disturbance is 9.6 acres (2017 ARR) as of the date of these <br /> findings. Existing facilities consist of a portal bench and coal handling/stockpile area; an <br /> access/haul road approximately '/2 mile in length leading from State Highway 139 up to the portal <br /> area; an office trailer, bathhouse and parking area on the East Salt Creek valley floor; and topsoil <br /> and construction material stockpiles,temporary waste storage pile, a supply storage area and <br /> sediment pond mid-way between the office area and the portal bench area. The two-level portal <br /> bench area includes a mine conveyor to a portal- mouth screen and crusher,which feeds product <br /> coal onto a stacker conveyor. Coal is stockpiled on the lower level bench and loaded into trucks <br /> for transport to market. Facilities on the upper level mine bench include four portal entries, <br /> including the fan portal and conveyor portal, water and fuel tanks, support trailers, a shop, a <br /> transformer and substation, ventilation fan, and rock dust bin. Disturbed areas include ditches and <br /> culverts for drainage and sediment control. A sediment cleanout stockpile is located adjacent to <br /> the sediment pond, and several small temporary coal waste storage piles are approved in the <br /> vicinity of the product coal stockpile. Material from these temporary stockpiles was periodically <br /> hauled to an approved permanent coal waste disposal site in the formerly adjacent Munger Canyon <br /> Mine permit area. The waste disposal site at the Munger Canyon Mine is now closed and fully <br /> reclaimed. The final certification and quarterly inspection for this pile was performed on April 16, <br /> 2008. On October 10, 2018,the Division issued its Final Decision to approve Bond Release <br /> Application SL-03 for the Munger Canyon Mine. In doing so,the Division terminated its <br /> jurisdiction over that mine. <br /> Coal is mined underground using room and pillar techniques. Prior to 1991, a total of 526,666 <br /> tons of coal had been produced at the mine. A total of 193,954 tons were produced in 1991, and <br /> 7,913 tons were produced in 1992. No coal was produced in 1993 through 1996. A total of <br /> 49,115 tons were produced in 1997. The operation was idle during 1998 and most of 1999. The <br /> mine was re-activated in the 4t'quarter of 1999, and coal production was re-initiated in February <br /> 2000. Coal production in calendar 2000 was 305,332 tons, with annual production ranging <br /> between 199,650 and 327,000 tons in subsequent years through 2010. The mine shut down their <br /> operations in December of 2010 and went into temporary cessation February, 2011. The <br /> operation has remained idle since then. When in full operation, maximum projected annual coal <br /> production is 500,000 tons, with a projected annual production of 300,000 to 500,000 tons. <br /> vii <br />
