response submittals. The Division conducted an Applicant/Violator System query on November 14, <br />2012 and found that the ownership and control information contained in the permit application was <br />consistent with the information in AVS and that there were no violations listed. The reclamation cost <br />estimate for the Munger Canyon Mine was reevaluated and updated with Permit Renewal No. 6. The <br />last liability estimate was calculated for Midterm Review No. 6 and was $68,238 and the new estimate <br />for RN -6 is $65,965.26 for a reduction of $2,272.74. This change in cost is mostly attributed to lower <br />revegetation seed prices. The Division currently holds a surety bond in the amount of $117,585.00 <br />which is greater than the calculated liability amount. <br />The Applicant/Violator System was queried again on February 15, 2013. The Division recommends <br />approval for the permit renewal. The proposed decision to approve the renewal was issued on February <br />15, 2013. <br />Publication of this proposed decision by the Division will initiate a thirty (30) day public comment <br />period, after which the renewal decision becomes final, provided there are no objections. <br />Description of the Environment <br />The Munger Canyon Mine is located in Garfield County, Colorado, approximately 20 miles north of <br />Loma on Colorado Highway 139. The operator leases a rail loadout at the town of Loma from the <br />Union Pacific Railroad. The rail loadout is located along a previously disturbed loadout siding, and <br />has been reclaimed. <br />The permit area encompasses approximately 1028 acres (1022.4 acres in the mine area, and 5.6 acres <br />at the Loma loadout). Existing affected area (mine area) is approximately 32.7 acres. Existing <br />disturbed area in the mine area is approximately 17.9 acres. Existing and permitted affected and <br />disturbed area at the Loma Loadout is approximately 2.9 acres. Total permitted disturbed area <br />(mine /loadout combined) is 20.8 acres. <br />Ownership of the coal is in the Munger Canyon Mine permit area is 100 percent Federal. No <br />additional coal production is proposed under the current permit. <br />Geology and Topography <br />The mine site is located at an elevation of approximately 5800 feet. Munger Canyon is located in <br />the Book Cliffs, just north of Grand Valley. This area is northeast of the Garmesa Anticline and on <br />the south flank of the Piceance basin. Local strata dip to the northeast into the Piceance basin at one <br />to three degrees and strike north - northwest. No faults have been identified in the Munger Canyon <br />mine plan area. The adjacent McClane Canyon Mine (north of the Munger Canyon Mine) is located <br />within a graben structure which is bounded by two large, high -angle displacement faults. <br />The Mount Garfield Formation is the coal - bearing formation in the Book Cliffs Coal Field. The <br />Mount Garfield Formation consists of fine - grained and medium grained sandstones and gray shales. <br />The Sego Sandstone underlies the Mount Garfield Formation and the Hunter Formation overlies it. <br />Included within the Hunter Formation are the massive cliff - forming sandstones which outcrop along <br />6 <br />
