Cattany <br />Division Direcor <br />Natural Resource Trustee <br />The Division has reviewed Trapper Mining Inc.'s Third Quarter 2006 Sediment Pond Inspection reports. <br />Trapper Mining Inc.'s third quarter 2006 sediment pond reports were received by the Division on October <br />2, 2006. Timely submittal of these reports is in compliance with Rule 4.05.9(17). Sediment pond <br />inspections were conducted by TMI on September 19, 25, 26, and 27, 2006. <br />The mine site experienced a greater than 100-yeaz storm event on September 15, 2006. On September 16, <br />2006, TMI measured 2.34" of precipitation had fallen at lower elevations of the mine site. All sediment <br />ponds functioned appropriately. Some scouring of drainage ways occurred but all ponds held up and did <br />not experience failure during or following the storm event. TMI noted which ponds needed maintenance <br />following the storm. <br />Only two ponds, Middle Flume No. 1, East Middle Flume No. 1, were reported to be discharging at the <br />NPDES point at the time of inspection. The dischazge was reported as a trickle or less than 1 cfs. Minor <br />maintenance items have been identified by the operator. Four sediment ponds require maintenance; <br />Johnson No. 6, East Pyeatt No. 1, East Pyeatt No. 2 and East Pyeatt No. 3. Two ponds require <br />identification signs to be replaced. TMI plans to seed the Deal gulch pond area in October. <br />Protection Specialist <br />C:/jhb/C81010/Sediment Pond Inspection/2006/3rd q 2006.doc <br />Cc: Dan Hernandez, DMG <br />Office of Office of <br />Mined Land Reclamation Active and Inactive Mines <br />
