(Page 2) MINE ID # OR PROSPECTING ID # M-2002-114 INSPECTION DATE 4/14/04 INSPECTOR'S INITIALS RCO This inspection was performed by the Division as part of its monitoring of Construction Materials 110 permits. The operator was contacted to set up a time for the inspection. The operator's representative named on page one was present during the inspection. The required permit ID sign was posted at the entrance gate. Permit boundary markers (labeled T-posts) were installed at the corners. All mining-related activity appears to be within the boundary. More markers along the west boundary might be helpful. A portable scale and scalehouse are located in the eastern access corridor. The area being mined is a natural terrace about 10 or 15 feet above the elevation of the access corridor. Excavation is proceeding according to the approved plan, and was begun at the southern end of the site. The eastem edge of the terrace material is being temporarily left in place to screen the pit operations from the county road. This visual berm will eventually be removed and the pit will daylight to the east. Pit slope grading has been carried out on the eastern and southern walls of the pit. The south wall is in its final position, and before placing topsoil and seeding it the operator should ensure that it meets the reclamation slope gradient in the plan. The east wall, which is the inslope on the back of the visual berm, is temporary and need not meet the final reclamation criteria at this time. No topsoil has been replaced and no seeding has been carried out, but the operator has planted several seedling trees on the final slopes. The trees are not required under the reclamation plan, but their addition to the site may enhance the revegetation of the site. The operator mentioned that irrigation may be used in the future, but care should be taken to not cause erosion. Topsoil has been stripped from areas to be mined, and stockpiled along the western boundary. Some areas are producing more topsoil than expected, and the operator was encouraged to salvage the maximum possible, to promote better revegetation. Some areas that have been affected, but not by actual excavation, still contain their topsoil. The operator was cautioned to not allow topsoil to be lost by erosion or during removal of gravel products, nor to become degraded or compacted by traffic running on it. It is better to strip topsoil from small areas that are planned for activities, so that a good quality topsoil is available during reclamation. There is a crusher set up next to the pit, which will be moved down into the pit after it is expanded more. Several gravel piles are presently located north of the pit, The onsite diesel fuel needs are met by use of an onsite tank in the west central part of the permit area. Though there are signs that there has been no past spillage, the operator should provide an impermeable secondary containment before the next operation begins. This is not a problem at this time. There were no noxious weeds observed. A few pieces of mining related debris and heavy equipment onsite. The size of the disturbed area is nearing the 4-acre size approved in the file. The operator is ready to topsoil and seed a significant area in the near future. Reclamation performed will act to reduce the overall reclamation liability, allowing the operator to lower the bond amount or expand operations into the central and northern portions of the site, as approved by the plan. The $8,000 bond is sufficient at this time. There were no problems found during this inspection. No further items were observed during the inspection.
