<br />Red Creek Within the Quarry Area <br />Rocky Mountain began ripraping Red Creek through the quarry area in March 2000. At <br />the time of the inspection, this work had been completed (photo 9). Due to the riprap, inspectors <br />could not view the erosion that had occurred on the banks of the Red Creek within the quarry <br />area. From visible remnants of the eroded bank viewed through the riprap, the erosion appeared <br />to be substantial. Photo ] 0 shows water visible in Red Creek within the quarry area. Photo 11 <br />shows water ~~isible above the ripraped area. Photos 12 & 13 show the 60 inch culverts which <br />carry Red Creek under the quarry haul road. The capacity of this crossing was increased in early <br />spring 2000. <br />The inspectors moved through the quarry to an area that, according to Mr. Stack, had <br />been cleared the previous winter. Immediately below this area had been graded toward the high <br />wall. The facility considered tltis area as a sediment basin as well, though there was no berm <br />construction (photos 14 &. 15). Photo ] 6 shows Red Creek adjacent to the graded area. <br />The inspection then moved to a wooded area surrounding Red Creek adjacent to a portion <br />of the mining area. In this area, Red Creek was flowing freely. The inspectors reviewed a pond <br />built by Mr. Stack that had washed out in 1999 (photo 17), as well as a natural rock slide area <br />(photo 18) and a rock slide attributed to blasting operations at the mine. <br />Ms. O'Comtor and Mr. Stack then walked through the active quarry area. Another <br />depressed area at the high wall immediately behind the plant was observed (photos 19 & 20). The <br />ground within this area was graded toward the high wall in an attempt to decrease runofffrom the <br />site. Next to the plant a fuel tank was observed as well as a small building holding other <br />chemicals (photo 21). Inspection of the facility concluded at this time, though representatives of <br />Rocky Mountain and Mr. Stack took the inspectors to the lower crossing area. <br />Lower Crossing <br />The lower crossing area is tl~e area in which Red Creek is directed under the road below <br />the quarry property. The crossing consists of three 36 inch culverts (photos 22). Heavy <br />sedimentation was observed in the area above the lower crossing (photos 23-30). <br />After concluding the inspection at the quarry, the inspectors met with the landowners <br />below the quarry to view sedimentation on their property and listen to their concerns. Photos 31 <br />through 35 show examples of sedimentation that have occurred on downstream property. <br />
