(Page 21 MINE ID # OR PROSPECTING ID # M- INSPECTION DATE /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 representative was not present during the inspection. The required permit ID sign was posted at the NE entrance gate to the site, and the permit boundary corners were marked by green steel T-posts. All disturbance appears to be contained within the permit boundary. There is an adjoining area of mining-type disturbance outside the permit area, containing a highwall and operations bench as well as small stockpiles of boulders. These features are located on adjoining land clearly outside the permit boundary, but have been documented adequately as being associated exclusively with a local irrigation company, and not with this permitted operation. There is no problem, but if the permitted operator begins to mine materials from here, this area must become part of the permit. The operation consists of removal of irregular, large material (riprap and boulders) from aquarry-type highwall, and the subsequent processing of some of it into smaller, uniform products. The highwall is on the south side of a knob located along the north permit boundary. Stockpiling and processing occur in the southern areas of the permit which are more level. There are several large. stockpiles of materials presently onsite, but no equipment is present. There is very minimal debris, no contamination and no noxious weeds. Highwalls consisting of solid rock may remain in heights no greater than 25 feet, with benches gently sloped outward for drainage. As noted above, the knob being mined lies along the north permit boundary, and is not entirely within the permit area. The top of the highwall is approaching the north permit boundary. If it approaches too close, the approved highwall configuration may not be attainable without reducing the final surface gradient by backfilling. Slopes created by use of backfilling of unconsolidated material will be gentler than a surface consisting of unblasted, competent bedrock. The operator must be aware that this could require use of a significant volume of material not presently onsite. Stockpiling and processing have apparently occurred on surfaces which still contain the native topsoil layer; no stripping was carried out and there are no topsoil stockpiles. This is approved in the plan, but care should be taken to ensure that no contamination, Toss or noxious weed infestation of the native topsoil occurs. Seedbed preparation for revegetation will occur after all stockpiles are removed. The site is nearly all occupied or affected by the permitted operation, with some areas more disturbed than others. The bond is currently $7,700. The reclamation costs are scheduled for review, and the new figures will be forwarded to the operator when they are prepared. At present, it is estimated that the current bond is adequate to reclaim the site. There were no additional items observed and no problems exist at this time.
