• <br />the operation will be minor. Estimated use for the crusher/screen plant is 2% of the annual tonnage <br />run through the plant, which, as described above will be a higher tonnage than that of this permit, <br />120,000 tons per year. This results in an additional consumptive use of 1.76 acre-feet per ear. <br />A summary of consumptive uses is given below: <br />Use T e Basis Acre-feet r <br />Lake Evaporation Evap records + precip. data 9.37 <br />Gravel Excavation Evaporation Evap records, tonnage mined 1.32 <br />Wetland Evaporation Evap records, area exposed 6.91 <br />Dust Control -Roads Tonnage and road use 0.20 <br />Dust Control - Cmsh & Screen Plant Plant data and throughput 1.76 <br />Totals 19.56 <br />The numbers above are for worst case consumptive use since the lake is calculated at maximum <br />surface area and it is assumed that the full mining operation will be taking place at the same time. <br />Once the operation is terminated, the only use will be lake evaporation, which will be 9.37 acre-feet <br />per year. <br />Once mining and reclamation is completed 28 to 30 months after the operation commences, 4.2 <br />acres of the original permit area will remain as a lake and the remainder of the land will be restored <br />to irrigation use.
