September 30,2013 C-1992-080/Carbon Junction Mine MLT ROADS—Rule 4.03 Construction 4.03.1(3) / 4.03.2(3); Drainage 4.03.1(4) / 4.03.2(4); Surfacing and Maintenance 4.03.1(5) and (6)/4.03.2(5) and (6); Reclamation 4.03.1(7)/4.032(7): • The reclaimed North Pit Haul Road has experienced severe erosion. Flow had gouged out the hillside ditch in numerous locations, to depths of 2 to 3 feet (Photo 8). The eroded material then clogged the ditch, forcing flow across the surface of the roadway (Photo 9). • The road surface was compromised throughout much of its length. The entire road, including the ditches, is in need of maintenance and restoration to the configuration approved in the permit. • The light use road that accesses the former Pond 2 area had also experienced some minor erosion of its surface. REVEGETATION—Rule 4.15 Vegetative Cover; Timing: • The grasses on the bench of the reclaimed North Pit were thriving. Three horses were grazing at this location (Photo 10). • Throughout the permit area, the warm season grasses appear to have been boosted by the monsoon moisture. The site appeared greener, overall, than it had appeared earlier this season. DOCUMENTS RECEIVED • During the records check, Mr. Amdor showed me the 1996 study conducted by Goff that had created Appendices 5-9 and 5-10 to the permit. During the Division's adequacy review of TR-17, we discovered that we did not have these two appendices, either electronically or in the hard copy of the PAP. Goff created a PDF of the study, and provided it to the Division for our use in evaluating the various design flows computed for the Carbon Junction drainage.
