McClane Canyon Complete Oversight Inspection <br />Colorado Division of Reclamation, Mining and Safety (DRMS) Permit ID # C-1980-004 <br />Tuesday, May 3, 2011, 1:00-4:00 <br />Operator: CAM Mining, LLC <br />Participants: <br />Mike Boulay, DRMS <br />Elizabeth Shaeffer, OSM, Badge # 377 <br />Chuck Silengo, CAM Mining, LLC <br />Weather conditions: upper 60's, partly cloudy, dry <br />This was a complete oversight inspection of the McClane Canyon mine site conducted jointly by Mike Boulay <br />of the DRMS Grand Junction Field Office and Elizabeth Shaeffer of OSM's Denver Field Division. Chuck <br />Silengo, representing CAM Mining, LLC, joined us for part of the inspection. This site is currently in temporary <br />cessation as a result of the Cameo Power Plant's shutdown. There was minimal activity at the mine site during <br />our inspection. <br />We checked the mine records at the office of J. E. Stover and Associates located in Grand Junction. The DRMS <br />mining permit expires in July, 2011; a permit renewal is in progress. The NPDES permit has expired and is <br />under administrative extension. CAM must update these records when the new permits are obtained. <br />The mine ID sign was intact and contained all of the necessary information (see Photo 1). We stopped at the <br />mine office so I could take the required mine safety training. <br />We began our inspection by visiting the archeological site that was discovered where the mining company was <br />planning to build a new waste site pile and sedimentation pond (Technical Revision No. 16). Mr. Boulay briefed <br />me on recent events that led to the reconsideration of the new waste pile construction due to the location of two <br />shelters in an overhanging rock outcrop and the contents of historical significance that were found at the site. <br />The operator has proposed a new location for a large pile further to the south which is still under review with <br />Permit Revision No. 2. ' <br />We then went to the temporary coal wastepile located above the sedimentation pond. There is an earthen berm <br />around the pile for protection of adjacent areas from runoff (see Photo 2). The clean water diversion ditch that <br />runs around this area and drains to East Salt Creek appeared to be functioning appropriately. All ditches and <br />disturbed area runoff report to the sediment pond (see Photo 3). There are many sediments traps and sumps that <br />appear to be functioning as designed. The sediment pond has a spillway that acts as both the primary and the. <br />emergency spillway and is operated manually when discharged (see Photo 4). The pond's water level was <br />about 1.5 feet below the spillway and the water appeared muddy. The pond embankment was stable. <br />In this area there is also a topsoil stockpile, which shows no signs of erosion (see Photo 5). There are a few <br />spots with minimal vegetation on the south-facing side of the pile. <br />The draining system at this site has an enclosed culvert that carries clean water away from the portal area and <br />other disturbed areas. This clean water diversion runs directly into McClane Creek. Dirty water goes into <br />sumps that run along the south side of the main road. Occasionally, the mine inflow water is pumped. When <br />this type of discharging occurs, CAM must monitor and test the mine water (see Photo 8). The mine was not <br />discharging water at the time of this inspection. The ditch that runs behind the warehouse was maintained. <br />I should note that there are cable lines running parallel to the mine road (see Photo 6). These fiber-optic cables <br />are now required at all mine sites to assist in locating underground miners in case of an accident. All miners are
