PERMIT #: M-1977-567 <br />INSPECTOR'S INITIALS: RCO <br />INSPECTION DATE: December 3, 2010 <br />OBSERVATIONS <br />This was a routine inspection performed by the Division as part of its monitoring of Construction Materials <br />110c permits. The site was not active and the operator was not present at the time of the inspection. <br />Acid And Toxic Materials: <br />The site is being kept free of debris, hydrocarbons and other contaminants. <br />Backfilling and Grading: <br />The south wall of the pit was reduced several years ago. There has not been any other backfilling or grading <br />performed recently. All other pit walls exhibit steep slopes as a result of excavation. <br />Complete Inspection: <br />There was no excavation or processing equipment at the site at the time of the inspection. <br />There is a low pile of fines or topsoil covering an asphalt pad (which has been observed and described in <br />previous inspection reports) in the north central portion of the permitted area. During this inspection it was <br />observed that the 12-inch earthen cap has been partially removed, exposing a portion the asphalt surface. It <br />is not known whether the cap material was removed to serve another purpose elsewhere, or if this was done <br />in preparation of removing the asphalt (as part of the reclamation). The operator should include discussion of <br />this activity in the annual report. <br />Hydrologic Balance: <br />The pit is dry: there are no seeps or areas of impounded water in the pit. No precipitation runs off the site. <br />General Compliance With Mine Plan: <br />The pit configuration is somewhat irregular, as it has been for a number of years. Though there may have <br />been minor excavation or removal of stockpiled material, no significant removal of material has been <br />observed in recent years. The operator should report all pit excavations or stockpile removal, large or small, in <br />the annual reports. The approved plan states that the pit slopes will be graded down to gentler gradients, and <br />this was discussed with the operator in 2006. No grading has been performed, and the pit slopes are still <br />mostly fairly. steep (except the south pit slope which was reduced). There is no sedimentation transported to <br />offsite areas due to the steep slopes, and all eroding material reports to the floor of the pit. However, the <br />concern about the slopes stems from the fact that some of the margins of the steep walled pit still contain <br />topsoil, which can be lost if it is not stripped back away from a slope prior to it sloughing. It might be too <br />steep for livestock also, which should be discussed with the landowner. This is not noted as a problem at this <br />time, but see additional discussion, below. <br />Reclamation Success: <br />The south wall of the pit was reduced by backfilling and grading, but no other reclamation has been <br />performed elsewhere in the permit. An existing condition, noted in the 2006 inspection report and still <br />applicable, is that the site is accessible to the landowner's grazing livestock, which will impede successful <br />revegetation by the operator. There are currently several areas which might not be disturbed in the future <br />and could be graded, topsoiled and seeded, but livestock would have to be excluded. This is not a problem at <br />this time. <br />Page 2 of 4
