North Thompson Ck. <br />Mr. Walker discussed the concrete base retained (former water flume) here in North <br />Thompson Ck., another former flume base downstream, and two additional concrete <br />bases retained in the Middle Fork/ N. Thompson Ck. DMG has discussed retention of <br />these structures with landowners and the USFS biologist. DMG will further research <br />these structures and address them in the proposed decision for this bond release. <br />We continued the inspection to the bridge upstream from Mine 1 that is currently <br />scheduled for removal, the new fan. site reclamation and reclaimed road, and the old fan <br />site reclamation and associated road. These areas and the roadway are stable. We <br />inspected the former flame bases in Middle Ck. as noted above, and we concluded the <br />inspection with observations of the former loadout pad and corridor. These areas aze <br />stable and well vegetated. <br />As indicated above, water treatment facilities noted are approved for retention. This <br />includes the former mine dewatering site and concrete manhole access at Mine 3, and <br />the treatment ponds at the former main facilities area. These areas appear to have <br />functioned well as designed, remain stable, and should continue to function as approved <br />for postmining retention. Mines 1 and 3 were both dischazging into the long pond during <br />the inspection, and the treatment ponds/cells were functioning as designed. The two <br />power poles to the Mine 1 portal azea are also approved for retention. This concluded the <br />inspection. <br />OSM has reviewed the bond release application package, and the revegetation success <br />sampling report provided in the application is currently being reviewed by OSM / WRCC <br />technical specialists. DMG has provided a thorough bonding /bond release history of the <br />mine to OSM subsequent to the inspection. <br />Please provide any questions concerning this inspection report to Henry Austin at <br />haustin@osmre.QOV or to (303) 844-1400 x1466. <br />
