• (Page 2) MINE ID # OR PROSPECTING ZD # M-90-094 INSPECTION DATE 01/23/98 INSPECTOR'S INITIALS RCO This inspection was performed by the Division as part of its monitoring of 112 pezmits. The operator was contacted about the inspection, and a time was arranged to meet at the site. The operator was present throughout the inspection. The required permit ID sign was posted on the onsite scalehouse, visible from the entrance to the permit area. The four corners of the permit area were adequately marked by yellow- painted steel posts. The permit area is bounded on the west by 23-1/4 Road. On the east and south sides are vacant fields {though i-70 passes on the south a short distance away from the south boundary line). The north side of the permit area adjoins undeveloped, commercial property owned by this operator, which presently is filled with small piles of earth and rubble, mainly concrete. The pit is located in the central north portion of the permit area. When active, it is dewatered, but at the time of the inspection was a frozen pond. The pit is mined toward the south and east, though that will soon change due to the quality of the deposit becoming poorer. There is still much area to the east and south within the permit, which has not been mined. The northeast part of the pit/pond is being backfilled. Material used for backfilling is excess overburden and the concrete rubble (mentioned above). There is a oroblem noted on Dgge one under the to8ic of "records". which relates to this backfilling with imported materials. The approved plan for this site is for the pit to become a pond, with finished slopes of 3:1, and all dryland areas topsoiled and revegetated. The operator is salvaging topsoil in sufficient quantities and has posted a $29,000.00 bond which was calculated to be adequate to reclaim according to this plan. The actual practice here is different, and will result in a different type of site at the conclusion of mining. The pit is being backfilled, which is allowed since finished surfaces will be no steeper than 3:1, but the nse of imp9r d ma r~a~ m b om Dart of the Dian, no matter what amounts are used. The operator must n ovid 'nforma 'on ~n h- form o a Not' a- ord~ng to the details contained in Rule 3.1.519). characterizing the imported material. This Notice will not affect the overall reclamation plan or change the post-mining land use. (Eventually, however, the operator will have to modify these aspects of the permit, to reflect the intended "commercial" land use rather than "rangeland", which is presently approved. This will impact the need for topsoil salvage and later revegetation, and therefore, the bond amount.) The abatement for this problem will be to D ovid h No i (s R 1 1. 1 )) by the date shown on the last Dage of this report, Topsoil is stockpiled on the east edge of the permit, a couple hundred feet east of the pit. There is an overburden pile south of the pit. Pitrun is stockpiled on the northwest part of the permit. This material is crushed in the processing area to the south of the pitrun, with the product stockpiled nearby. There were no fuel storage facilities observed and no contaminated soils. There was a small amount of equipment and parts present, and minor amounts of debris. Mining equipment observed included a couple of portable conveyors and a screen deck. The area near the entrance contains a scalehouse and truck scale. These items are portable. The house is on skids with no footers, and the scale has concrete footers with earthen ramps. These will require minimal bond to remove. There is a small pile of oversized material present here, and a pile of woody debris which can be burned in place. Much of the southern portion of the permit area is not disturbed and is covered by tamarisk thickets.
