(Page 21 • MINE ID 71 OR PROSPECTING ID k M-2000-103 INSPECTION DATE 10/6/00 INSPECTOR'S INITIALS RCO OBSERVATIONS This inspection was performed by the Division as ogre-operation inspection for a new 110 permit application. The operator was contacted about the inspection and a time was arranged to meet at the site. The operator and his agent (named on page one) were present throughout the inspection. Several items were discussed during the inspection, including the application exhibits, adequacy review questions, method of mining, timing of reclamation, and bond calculation. The site is located on a dry, wooded hillside, and includes a preexisting level pad. The site is accessible via a short, fairly steep gravelled road leading up from CR 213 ILa Posta Rd.l. The road in not included in the permitted area. The entire pad is included in the proposed permitted area. The pad will eventually become a residential building site. A domestic water well has been drilled, cased and capped on the north end of the pad. The pad will remain approximately the same size during the operation. The west edge of the existing pad contains a nearly vertical cut wall in the hill slope, which will be "laid back" to gentler gradient as soil material to the west is excavated and removed from the site. The exposed soil profile indicates that the soil is ten feet or more deep. No gravel layer was exposed in this cut. At the eastern edge of the pad is the fill slope, which will not be affected during the operation. The operator has already thinned the existing woody vegetation on the hill above the pad, exclusively inside the permit boundary. Beyond the proposed boundary the slope is unaffected. Minimal handling of woody debris will be necessary as the slope is laid back. It is recommended that woody debris for any debris) not be allowed to accumulate at the site, since this could become a bondable reclamation task. Likwise, allowing weeds (including noxious weeds) to infest the site will cause the reclamation bond amount to increase. There is a small patch of thistle on the pad at the top of the access road, which must be monitored and treated as required. Mining is to occur by pushing material down over the cut slope onto the pad, working the slope farther to the west on the hill. This will increase the surface area of the affected slope, but decrease and eventually eliminate the vertical cut wall. The natural slope is between 2:1 and 3:1. Removing material in a wedge will make the slope steeper, but not steeper than 2:1, according to the mining and reclamation plans. To control sediment transport and runoff, an uphill diversion ditch will be cut, to direct drainage to small sediment ponds on the north and south ends of the pad. The runoff from the pad is to be directed to the ponds also, via a gentle 1 °~ slope on the pad surface. The gravelled road exhibits gullying from uncontrolled runoff from a portion of the pad, which is evidence of the need for maintaining adequate controls on the site. There are natural swales just outside the north and south ends of the permitted area, where upslope drainage concentrates, and where the sediment ponds might be designed to report to. Filters or riprap may be needed at those locations. Gullying must be monitored, and remedied as needed during the operation. There were no further observations, and no problems noted at this time.
