OBSERVATIONS <br />A pre-mining inspection of the "Summit Pit" was conducted on November 9, 1988, <br />by Camille M. Farrell of the Mined Land Reclamation Division, Rob Mangone and <br />Steve Schnurr with Rocky Mountain Asphalt, Inc., Michael D. Stanton, <br />consultant for Rocky Mountain Asphalt, Inc. and P.J. Anderson, attorney for <br />Rocky Mountain Asphalt, Inc.. <br />The previously mined and released area was observed. Material slouching on <br />the west-facing benches was observed; minor amounts of vegetation was <br />established. The "pit" floor was revegetated rather densely; the stream <br />channel was observed to be incised in bedrock. <br />Mining and pit development, pit-wall and bench stability, sedimentation <br />control and reclamation of the proposed plan were discussed. The Division <br />expressed concern about re-creation of the two ephemeral stream channels <br />located within the proposed quarry excavation, structural and surface <br />stability of the proposed 70 decree angled granite highwalls, and adequate <br />sediment control structure design and implementation. The Division suggested <br />that a geotechnical stability analysis be conducted to demonstrate pit wall <br />stability as it relates to the Performance Standards set forth in Rule 6 of <br />the Mineral Rules and Regulations. <br />A portion of the undisturbed area proposed for quarry excavation was <br />observed. Oakbrush, Douglas-fir, blue arama and wheatgrass were some of the <br />species observed. The natural slopes of the undisturbed area ranged from <br />approximately 2H:1V to nearly 1H:lY, well vegetated, with some areas of <br />exposed rock oiTtcropping. ^ <br />Mr. Rob Mangone <br />Rocky Mountain Aso halt, Inc. <br />1910 Rand Avenue <br />Colorado SDrings, Colorado 80906 <br />3421E cmf <br />
