Transit Mix of Pueblo, Inc. - East Pit Phase 1
Projected Depletion Analysis (February 2012 - January 2014)
[1] Phase 1 of the Pueblo East Pit has approximately 16 5 acres of exposed ground water surface area.
[2] Gross Evaporation Rate equals 4 17 feet per year, based upon NOAA Evaporation Atlas Monthly distnbution based upon SB -120 Guidelines
[3] Gross Evaporation equals [1] x [2].
[4] Effective Precipitation Rate equals 70% of total precipitation, based upon NOAA Pueblo Memonal Airport weather station.
[5] Effective Precipitation Credit equals [4] x ([ 1] -5 6), based upon 11 1 acres of non - irrigated and non- phreatophyte area in Phase 1.
[6] Average monthly potential consumptive use in Blaney - Cnddle analyses for Phase 1 based on a depth to ground water of 6 feet Values limited on monthly basis to gross evaporation in [2]
[7] Phreatophyte Reduction Credit equals [6] x 5 6 ac, based upon 5 6 acres of 100% canopy cover.
[8] Total natural vegetation credit equals [5] + [7]
[9] Pond Evaporation Replacement Requirement equals [3] - [8].
[10] Dust control depletions are assumed to be 100 % consumptive and arc based upon past maximum seasonal dust control pumping volumes
[11] Phase 1 replacement requirement equals pond evaporation depletion plus the water used for dust control [9] + [ 10]
