INSPECTION REPORT August 8, 1991 The Corley Company PO Box 1821 Colorado Springs, Co Newlin Creek mine Page 1 Personnel Present During the Inspection: Ray Curby The Corley Co Kathy Begej Colorado Mined Land Division Gary Fritz Albuquerque Field Office/Office of Surface Mining IF244 Weather and Ground Conditions: Cloudy and warm; dry on the mine, afternoon showers while inspecting records GENERAL COMMENTS This was a complete oversight inspection. The State RA was notified regarding my schedule and were able to send someone with me to conduct a joint inspection. Mr. Curby was not at the mine initially but joined us later as we inspected the Rex Carbon Portal area. This small underground mine was worked for years on the lower bench (Shamrock) and later developed and eventually ended up on the upper bench (Rex Carbon). Most of the mine area was regraded and reclaimed prior to April of 1990. The haul road connecting the two benches has been left per mine plan approval. In addition, there are three temporary sediment ponds, two for the Lower reclaim and one on the upper area. Temporary diversions for undisturbed area, water above the reclamation on the Rex Carbon pad are also still in place. The diversion was checked for stability, no problems were noted but the State inspector suggested that the outfall be brushed to reduce flows in order to reduce the chance of erosion and eliminate future maintenance. The sediment pond on the lower end of the area had a small amount of standing water but there was no evidence of a recent discharge. The comment was made by Mss Begej that the inflows for the pond needed to be reshaped and strengthened to prevent erosion. She .d id not specifically indicate as to how that was to be done but left it up to the operator. There are sheet flows from the reclaimed area above the inlet that will have to be directed into the system. In
