As a consequence, ground conditions within the Carbon <br />Junction Mine permit area were dry and no standing water or patches of snow were observed. <br />At the upstream end of the riprapped portion of the Carbon Junction, repairs made to a scour <br />hole in 2010 appear to have been successful. No new erosion was observed at this location. <br />There was an accumulation of sediment in the channel immediately upstream of the <br />riprapped portion (Photo 1). <br />OTHER (SPECIFY): <br />A collection of spray paint cans, shot through with small caliber bullets, and burned, was <br />observed adjacent to the south side of the riprapped Carbon Junction channel (Photo 2). <br />ROADS — Rule 4.03 <br />Construction 4.03.1(3) / 4.03.2(3); Drainage 4.03.1(4) / 4.03.2(4); Surfacing and Maintenance <br />4.03.1(5) and (6) / 4.03.2(5) and (6); Reclamation 4.03.1(7) / 4.03.2(7) <br />0 Roads within the permit area were predominantly dry. <br />• The site of the reclaimed Sediment Pond 1 was easily accessible by vehicle. <br />Number of Partial Inspection this Fiscal Year: 6 <br />Number of Complete Inspections this Fiscal Year: ; Page 2 of 5 <br />
