(Page 21 MINE ID # OR PROSPECTING ID N M-1981-220 INSPECTION DATE 4/15/02 INSPECTOR'S INITIALS RCO This inspection was performed by the Division as part of its monitoring of Construction Materials 112 permits. The operator's representatives named on page one were present throughout the inspection. This site was active at the time of the inspection, with native material on the floor of the western end of the pit being ripped and dozed into piles for the upcoming contract crushing. This will result in that part of the floor being lowered about 4-6 feet. After processing and removal of this material, this part of the pit will be reclaimed, and excavation will continue toward the east. Upcoming reclamation on the west end will not include the unreclaimed disturbance from pre-law mining which lies outside the permitted area. Some mining has already occurred to the east of the floor activity described above, resulting in a partially stripped and benched cut wall on the east. Much unmined area in the permit remains toward that direction. Future mining will proceed eastward, the floor will daylight on the south side, though presently both sides of the ridge daylight to the floor. The operator must exercise care in the stripping and excavating of new areas, to avoid causing material to be dislodged and roll down slope. That could potentially cause damage to areas outside the permit boundary, which is a possible violation. The undisturbed areas of the permit contain juniper and pinon pine, whose removal will be necessary before mining, and whose disposal could present some handling problems. Some slash could be mixed with the soil, or left piled for wildlife habitat. No clearing of woody vegetation should occur outside the boundaries. The operator should ensure that all permit area boundaries are adequately marked in the new areas where the operation will grow. It was extremely windy on the day of the inspection, which emphasized to the importance of adequate topsoil protection. Due to the configuration of the site, after the west end is reclaimed, it will be a long time before there is enough operating room to reclaim much more area. Stripped topsoil will therefore probably remain stockpiled for a long time. If not placed in piles that are configured to afford erosion protection and ease of establishing protective vegetation, much could be lost or deteriorated. Looking down the road to eventual reclamation of this operation, adequate topsoil protection must be assured in the short-term. There were no additional items observed or discussed. No problems exist at this time. All responses or questions about this inspection report should be directed to this inspector at the Division's Durango Field Office.
