This inspector attempted to contact the operator but it is not known if such contact was successful. The operator was present at the site during the inspection. Several items noted as problems were to have been addressed by the operator, by the due date, and oroof of having addressed them su~itted to this office by hs aT date. Such written proof had not been submitted by the due date, had not been submitted by the date of the inspection (and in fact still has not been submitted at the time of this writing!). The onsite problems have been corrected satisfactorily, which the record now reflects. The Qperator must still submit a summmarv of the corrective actions performed. their dates of comoletion. etc.. ae spQll.d o+ ~n h +nepection report of 06/11/98. The operator was to install a permit ID sign, which has been done. The diesel generator used by the operator was to be moved from the proximity of the gulch, which has been done. It is now about 20 feet or more from the gulch, and mounted on a timber footing with an iaq~ermeable plastic membrane under it. The membrane has caught a significant amount of waste oil that has leaked from the generator in the short time since its relocation. Please monitor how full the sump becomes and the condition of the membrane! The other generator, left onsite by the former operator, has also been moved away from the gulch. It has not been operated, and does not pose a problem placed here without fluid containment underneath. The gulch drainage has been improved, i.e., it is well defined, unobstructed by mining related material and is not affected by runoff or drainage from the mine or pad. The edge of the pad facing the gulch will have a plating of clean material placed there in the future, after grading of the waste material to be placed there has occurred. Some surface grading has been performed at the upstream end of the overflow pond, which will more adequately direct runoff into the pond. (Some attention should be paid to the erosion on the berm outelope itself at that upstream end of the pond too, and repair it.) The pad surface drainage has been improved. The sump is being cleaned out without chance of contaminated runoff to other parts of the pad or gulch, and all stormwater is controlled by directing it toward the foot of the cut wall. The ore storage area (for piled or sacked ore) is on the central part of the pad toward the foot of the cut wall. The sump to capture mine drainage has been enlarged. It has a second cell closer to the gulch. The second cell ie deeper, is located along the foot of the cut wall and seems to contain only clarified water, not the muddy water of the first cell. The walls of the deeper cell are cut into the native colluvium, not mine waste. The two cells appear to very adequately allow percolation of the drainage, impoundment was minimal. The pad level itself is being raised by about 8 feet. As new waste rock is removed from the mine (which is minimal at this time) it is placed in an 8-foot lift at the NW end of the pad, in such a manner that no muck goes down the face of the waste rock outslope. The entrance to the pad is being re-established on top of this new material, and will eventually replace the existing one at the foot of the cut wall. This will allow the operator to place waste there to buttress the wall (there has been sane minor sloughing at that NW end) and to lessen
