- 3 • <br />If vehicular conveyance in excess of 10,000 lbs, gross weight <br />over Stone St. in Morrison is allowed to resume by a Supreme Court <br />ruling of pending Case No. 26729, then approximately 30% will be <br />via Colo. 8, Stone mot., County 93 (Hogback Rd.), Colo. 26, <br />Interstate 70 and all legal truck routes branching therefrom. The <br />remaining approximately 70% via Colo. 8 end 285. <br />Average daily haul unit round trips of 180 to 270, with <br />sporadic demands causing occurrences to exceed these figures. <br />Haul roads from the loading area to the highway is paved. <br />Arriving north and south traffic will be provided with decelerating <br />and turn lanes within the entrance; also an accelerating lane for <br />the departures to the south. For more information, refer to the <br />site plan. The entrance, access roads and highway are posted for <br />precautions and direction. <br />The operation area is fenced and posted. Refer to the site <br />plan for arrangement and location. The fence is constructed of <br />steel posts with three to four barb wires. The signs give orders <br />to keep out and that there is frequent blasting conducted in the <br />area. The routine for blasting preparations include posting men <br />at strategic points to observe the surrounding areas. They are <br />located along the eastern and western limits of excavation and in <br />Strain Gulch on DMP's western boundary. The detonator must <br />receive clearance from these men. <br />The operational area is remote in that the nearest residence <br />is at least 3500', it is well shielded and screened by natural <br />ground topography and there is a prevailing wind from east to <br />west through the operations that carries the effects away from <br />what residences there are in the area. There has never been any <br />reason to restrain the hours of operation, which is due to these <br />natural controls coupled with those constructed into the operation. <br />The days of operation are Monday through Saturday, <br />The size of the area to be worked at any one time will be the <br />total approx. area of 57.4 quarry acres. The entire area will be <br />required to gain access to the outer and highest limits o:E excavation. <br />The most practical and economical procedure to mine the area is <br />to develop the highest bench elevations first and then the lower <br />benches in their respective order of elevation. The mining timetable <br />is estimated to be as outlined on the Quarry Layout by th~a CSMRI <br />of December 1974. According to this plan it is estimated that <br />35 million tons can be quarried from this area and that an average <br />
