(Page 2) MINE ID # OR PROSPECTING ID # M-1976-020 INSPECTION DATE 10/14/04 INSPECTOR'S INITIALS RCO.HHP.KLS.WHE OBSERVATIONS This partial inspection was pertormed by the Division as part of its monitoring of Construction Materials 112c instream mining permits. The operator was contacted about scheduling the inspection. The operator's representative named on page one was present during the inspection. Also present onsite with the operator during the inspection were Greg Lewicki and Ben Miller, of Lewicki and Associates. During the inspection, Terry Miller and Donna Thompson, representing the landowner, arrived and accompanied the inspectors. The required permit ID sign was posted along the entrance road to the site. Boundaries were not inspected during this inspection. No recent activities have encroached on the boundaries. There was no activity at the site during the inspection. There was no mining equipment, processing equipment or stockpiled material. Primary features observed included the cabled riprap and in-channel jetty installed on the west bank of the western (secondary) channel, as part of the recent amendment. The riprap structure appears stable: the bank exhibits no erosion or sloughing, the blocks have not shifted or settled visibly, the coarse fill between the blocks is intact, and some revegetation is becoming established. (There could be some improvement in the revegetation on this slope, and this area will be checked for that in the future.) The jetty also appears stable and intact. The river flow was fairly low at the time of the inspection, at an amount typical for this season. Signs of the September high flows were apparent on the gravel bars throughout the stretch of river this permit contains: new deposits of large cobbles and boulders were the uppermost fraction on many of the gravel bars. No (west) bank instability was apparent. The natural river channel in the northern end of the permit area widens significantly, and apparently reduces it velocity, which explains much of the new deposition of boulders. The channel also tends to meander between banks, among the numerous gravel bars, some of which are nearly as high as the eastern river bank. The condition of the channels in this northern end of the permit tended to support an observation made during the onsite discussion that channel stabilitywould be best achieved by a carefully followed plan of sustainable harvest of material, especially in this upper end of the channel. The bond amount is $z6, zss~ and was reviewed in 2003. No significant changes have occurred since then, and the bond is considered to be adequate at this time. No further items were observed during the inspection.
