1 Phase 2 maximum anticipated exposed ground water surface area is 5 0 acres.
[2]Gross Evaporation Rate equals 4.17 feel per year,based upon NOM Evaporation Alas.Munti,iy distribution based upon SB-120 Guidelines.
[3]Gross Evaporation equals[I I a[2]
[4]Effective Precipitation Rate equals 70%of total precipitation,based upon NOAA Pueblo Memorial Airport weather station.
[5]Effective Precipitation Credit is not claimed in Phase 7.
[6]Average monthly potential consumptive use in Blaney-Criddic analyses for Phase 7 based on a depth to ground water of 4 feet.Values limited on monthly basis to grass evaporation in 121
[7]Phreaiophyte Reduction Credit equals(6)x 5 0 or.based upon 5.0 acres of 1005E canopy cover.
[8]Total natural vegetation credit equals[5]+[7].
191 Pond Evaporation Replacement Requirement equals 131-18I.
[10)Annual production limited to 250,000 tons,or 7.4 ac-fl of depletions from 4%water content by weight of the mined aggregate tctnovod from Phase 7 The monthly rate rosy vary as long as the annual amount is not
exceeded.
[I']Phase 7 replacement requirement equals pond evaporation depletion plus water lou with aggregate removal[91+(I0J.
