(Page 2) MINE ID # OR PROSPECTING ID # M-1977-053 INSPECTION DATE 6114/06 INSPECTOR'S INITIALS RCO OBSERVATIONS This inspection was performed by the Division as part of its monitoring of Construction Materials 112c permits. The operator was contacted about the scheduled inspection. The operator's representatives named on page one were present during the inspection. The site was active during the inspection. The wind was extreme the day of the inspection, and though many agricultural fields were eroding, the dust blowing from this site was mainly due to crushing operations, not blowing soil. The required permit ID sign was posted at the NE entrance gate to the site. The E and N permit boundaries are the fencelines. The W boundary is partly along the fence, and partly setback from an irrigation ditch by 50-100 ft (as shown on permit maps). The S boundary runs approximately along the edge of an irrigated field. All boundaries are well marked except the western end. The operation is mining toward the west, and the operator should ensure that this boundary is also well marked. Topsoil is stripped ahead of excavating the aggregate. All topsoil is piled above the highwall on the N and S side of the pit. As the operation moved west, deeper topsoil is encountered. There is sufficient topsoil of perform the required reclamation. The operator should ensure that new stockpiled topsoil is seeded for protection. The approved operation includes excavation, screening, crushing, stockpiling and asphalt batching. All activities are currently carried out onsite, except asphalt batching though that equipment is present for use. Much of the pit floor is occupied by stockpiled product. The floor is level and dry, is not going to be mined deeper. The active highwall is vertical. Some of the N and S slopes have been graded closer to the final 3:1 reclamation gradient. The operator is reminded that all partial reclamation possible should be carried out to help the bond remain lower. The operator stated that he wishes to add land to the permit on the south. This would be through an amendment, which will require a bond recalculation. At this time, however, this office is scheduled to review the bond. New figures will be mailed to the operator for review. If an increase is indicated the operator will have 60 days to provide it. No further items were observed during the inspection.

This was a newer storage location, and there was no spilled diesel noted. Though this is not noted as a problem, the operator must provide such impermeable containment for diesel and all other fluids if they are to be stored onsite. An earthen berm is not sufficient.
