MINE ID # OR PROSPECTING ID #: M-1977-A8.5 <br />INSPECTION DATE: line 2, gnin INSPECTORS INITIALS: 11F <br />OBSERVATIONS. <br />This was a monitoring inspection of the Gravel Pit No. 8 operation; DRMS file No. M-1977-485, operated by <br />Baca County. This site is located approximately 18.5 miles south of Pritchett, Colorado in Baca County. I, <br />Jared Ebert of the Colorado Division of Reclamation, Mining and Safety conducted the inspection. Mr. <br />Clarence Stevenson of Baca County accompanied me on the inspection. <br />This is a 160 acre 112c mining operation. The primary affected area is located in the northwestern corner of <br />the permit boundary. The total affected land was estimated to be about 18 acres based on the site <br />observations and a 2009 aerial photograph of the area. At this time, the Operator is only allowed to affected <br />20 acres of land at a time. Prior to affected additional land beyond the allowed 20 acres, the Operator will <br />need to reclaim portions of the affected land that will no longer be impacted by the mining operation, or <br />submit a Technical Revision to the current approved mining plan to increase the amount of affected land that <br />can occur at any one time during the mining operation. <br />The pit excavation is about 20 to 25 feet deep. The excavation is oval shaped with gentle pit slopes. The <br />Operator is excavating material at a 3:1 horizontal to vertical ratio slope. The operation is slowly advancing to <br />the south and to the east. A haul road runs from the entrance of the mine site to the base of the pit where <br />the mined material is stockpiled. Topsoil has been salvaged in advance of the excavation and placed in berms <br />adjacent to the pit slopes. <br />There is a pre-law excavation located at the northern end of the affected land. The slopes of this excavation <br />vary from fairly steep 1:1 slopes to gentle 3:1 slopes. Native grasses and shrubs and trees have established in <br />this area. Overall, the area is stable with only minor erosion gullies present. <br />Figure 2.) From the western end of the affected land <br />looking east into the pit excavation. <br />Figure 1.)
