(Page 2) MINE ID # OR PROSPECTING ID # M-1977-568 INSPECTION DATE 3/21106 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 named on page one was present during the inspection. The site was identified by the required permit ID sign posted at the NW entrance gate. Most of the permit boundary was marked (at the corners), though more markers should be placed (along the sides) to makethe boundary more visible. The site was not active at the time of the inspection, though it has been recently operated. Most of the county's asphalt is batched at this site, and the equipment was present in the central portion of the permit, up on unmined ground. Recently electrical power was supplied to the site. Overhead lines and transformers adjoin the site east of the plant, and lines are buried across to the plant. Diesel fuel is stored in a 3000-gallon tank west of the plant, for use by onsite and road maintenance equipment. The tank is not The pit covers several acres, has a flat dry floor, and most stockpiled materials are stored down in the pit. There was no mining or crushing equipment onsite. Past crushing has been carried out by private contractor. There is still unmined land to the east, south and west of the pit. All pit slopes are nearly 1:1 angle of repose, with a height ranging from 15 to 20 ft. No pit slopes are graded and no reclamation has occurred. Topsoil is bermed along the south side of the pit. The map notes that topsoil is also bermed along the north side, but there is no topsoil stored there. There is a large pile of reiect/fine material on the north side of the pit floor, that is browner than the processed gravel, and it is suspected that this pile contains some topsoil too. Past mining and processing may have affected non-stripped topsoil. This is probable since the native topsoil laver was visible along over half of the highwalls in the pit, and much topsoil has been falling into the pit. Topsoil that has been bermed along the south edge of the pit is even falling into the pit and being degraded and wasted. These topsoil issues are noted collectively as a problem in this report. The operator must No further items were observed during the inspection.

See the last page for the correction date. The recent annual report maps do not closely conform to the original permit maps (mainly not drawn to scale and don't include features near western boundary). This is not a problem, but the operator should endeavor to generate a corrected map showing updated features, to be submitted for future annual reports.
