May 19, 2015 C-1981-019/Colowyo Coal Mine RDZ <br />The construction work on the primary spillways for the Work Area and Prospect Ponds is complete. Erosion <br />control wattles were in place below the Work Area Pond; the need for maintenance of theses BMPs should be <br />continually monitored. The leak at Prospect Pond could not be assessed since water was discharging through the <br />weep holes. <br />Other observations regarding the ponds: <br />Gossard Pond needs to be cleaned. <br />No problems were observed with any of the embankments of the ponds. <br />No problems were observed with spillways of the ponds. <br />Some emerging vegetation was seen on the Prospect embankment. <br />The ditch above the Gossard Pond was inspected. Sediment was almost up to the weep holes on the stand pipe. <br />This ditch gets cleaned routinely per Kurtis Blunt, since it gets a steady load of coal fines from the Gossard plant. <br />ROADS — Rule 4.03 <br />Construction 4.03.1(3)/4.03.2(3) <br />Drainage 4.03.1(4)/4.03.2(4) <br />Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and (6) <br />Reclamation 4.03.1(7)/4.03.2(7): <br />The haul road near the administrative building was being cleaned of mud during the inspection.
