<br />t and over-the-road trucks for delivery to off-site projects. A water truck will be <br />' employed as appropriate for dust abatement and miscellaneous service. Fue] and utility <br />type vehicles will be used for transport of men and materials. <br />' No major water diversions will be required. Some minor diversions will be <br />implemented to divert runoff azound the working pit as appropriate. A working sump <br />' may be maintained in the mine to channel runoff that would otherwise be intercepted by <br />' the pit. <br />The average thickness of the aggregate and the overburden is unknown at this time, <br />' but will be provided once initial mining begins. <br />The aggregate is described in the Colorado Geological Survey document ~~ited above <br />' in the section on geology. The mining plan map has been based on the following <br />assumptions: <br />1 1. Aggregate Weight: 2,900 lbs/cubic yard. <br />2. Aggregate Reserve: 2,300 tons/acre foot (10% process loss). <br />Phase I under the 111 is being mined for the Boulder Peazl Street contract. <br />' Phase II will be mined once a 112 permit is received by transfer under the <br />conditions of the legal conforming use issued by Boulder County. (EXHIBIT M.) <br />' Phase III will be the initial mining phase once an amendment to the 112 i~ approved <br />and Boulder County has approved special use for mining for the additional acrc~age within <br />the area owned by the Varra Companies. <br />' It is anticipated that approximately 800,000 cubic yazds of the 4,356,000 cubic yazd <br />reserve will be mined within 10 years and that 250,000 tons per yeaz would represent a <br />' forseeable maximum extraction rate. Reclamation will be accomplished prior to the <br />' first feasible growing season subsequent to exhausting each phase. <br /> <br />1 <br /> <br />
