(Page 21 MINE ID # OR PROSPECTING ID # M-1984-026 INSPECTION DATE 2/26/02 INSPECTOR'S INITIALS RCO This inspection was performed by the Division as part of its monitoring of Construction Materials 112 permits. The operator was notified but was not present during the inspection. The required permit ID sign was posted outside the locked gate. It contains the operator's name and correct permit number, but also contains an additional permit number lof pit #2 which was added during the conversion in 19981. The sign should be corrected to contain only the correct number. While the operator is updating the sign, please refer to Rule 3.1.12, and ensure that the remainder of the required language is also included on the sign. At this time, this topic is not considered a problem. The permit boundaries are approximately marked by fencelines and ditches. There is no offsite activity. The permit area contains two separate pits, separated by an unmined area in the center. This central area will be mined eventually, but not until the east and west pits are finished. The central area contains a portable truck scale and scalehouse. The scale is 10' x 70' x 3'. It is transported in 2 pieces. The pits are about 20 feet deep. Several pit slopes have been graded to their final gradient. In the west pit, the west slope and the south slope are 3:1, while the north slope is about 2:1. Existing slopes are covered in annual weeds. All slopes which are in their final location should be graded to final gradient. No slopes have been topsoiled yet. There is topsoil stockpiled in several places in the permit area. The piles are small, but if the reclamation plan allows a pond as the post-mining land use, then topsoil needs are limited to the areas above the final high water line. The topsoil piles are also weedy, and they should be sprayed, since replacing weedy topsoil will make reclamation more difficult. Likewise, all graded slopes should be topsoiled and seeded since slope revegetation may take longer to attain. There is a pile of about 100 cubic yards of imported concrete rubble placed against the north pit slope of the west pit. Much of it has exposed rebar and steel rail imbedded in it. This might be exported to be used as riprap somewhere offsite, in which case the operator should inform the Division when that is done. Conversely, it is possible that the operator wishes to use the material as inert backfill somewhere in the pit. There would be two items to comply with before that can be possible: the operator must first provide the Division with a Notice pursuant to Rule 3.1 .519) characterizing the imported material and describing its use on the site. This would be a technics( revision which the Division would review. Second, the operator must also ensure that the material would not be placed below the waterline due to water quality impacts from ferrous materials. At this time, though the item is not a problem in this report, the operator should contact this Division to discuss the material and its onsite or offsite use. There is evidence on many of the lower slopes of water in the bottom of the pit, to a depth of a few feet. It is not clearly shown in the file how deep the pond will be when final reclamation is finished, nor the actual length of slope or acreage of the area tv be topsoiled and seeded in final reclamation. There is a significant amount of fine/reject material in the pit, which will presumably be spread out during final reclamation. There is a small screen operation set up in the west pit. The operation is fairly clean, with no observed contamination, but the operator must remove the open containers of waste oil and fuel. At present there exists a potential to adversely affect the groundwater due io inadequate storage of hydrocarbons. There is no spill yet, and no problem in this report, but the fluids must be removed promptly, and all future fluids stored onsite must have secondary containment. There is a stockpile of topsoil in the central unmined area, which appears to be recently borrowed from. Since it was mentioned above that the area to be topsoiled is not precisely known, and the topsoil needs are therefore not known, there should be no topsoil removal from stockpiles. Not far from that pile is a new pile forming, composed of imported sod, topsoil and corral cleanings. There is a pile of about 100 cubic yards. This also did not originate in this permit area. The operator must provide this Division a Notice about the importing and use of this material also. A third item noted in this central area are two pieces of the steel structure of an old bridge. There are two intact pieces, each measuring over 100 feet long, ten feet high, and 1 to 2 feet thick. (The name plate reads "Colorado State Highway Department 1929.") It is presumed that these will not be used onsite, so the operator must remove them. Until all these imported items are removed, they are a reclamation liability to be bonded for.
