Transit Mix of Pueblo, Inc. - East Pit Phase 7
Projected Depletion Analysis (February 2014 - January 2016)
[ I J Phase 7 of the Pueblo East Pit has approximately 5 0 acres o(exposed water surface area
(2J Gross Evaporation Rate equals 4 17 feet per year, based upon NOAA Evaporation Atlas Monthly distribution based upon SB -120 Guidelines
[3] Gross Evaporation cquals [ I ] x (2J
[4] E(fecuve Prccipnation Rate cquals 70 %of total precipitation, based upon NOAA Pueblo Memorial Airport weather station
[5) Effective Preciprtauon Credit is not claimed in Phase 7
(61 Average monthly potential consumptive use in Blaney- Cnddle analyses for Phase 7 based on a depth to ground water of-4 feet Values limited on monthly basis to gross evaporation in [2]
(7f Phreatophyte Reduction Credit equals (6] x 5 0 ac, based upon 5 0 acres of 100 -a canopy cover
8J Total natural vegetation credit equals [5] - [71
1[[ 9J Pond Evaporanon Replacement Requirement equals [3] - [8]
10J Annual production hmued to 1,000,000 tons, or 29 4 ac -R of depletions from 4 9,t water content by weight of the mined aggregate removed from Phase 7 The monthly distribution is based upon past operating
pattems The actual monthly rate may vary as long as the annual amount is not exceeded
[11 ] Phase 7 replacement requirement equals pond evaporation depiction plus water loss with aggregate removal [9] - (10]
