Table 4 <br />Transit Mix of Pueblo, Inc. - East Pit Summary <br />Projected Depletion Analysis (February 2014 - January 2016) <br />[11 The Pueblo East Pit has approximately 19 7 acres of exposed water surface area in Phases 1,2 and 7 <br />[2] Gross Evaporation Rate equals 4 17 feet per year, based upon NOAA Evaporation Atlas Monthly distribution based upon SB -120 Guidelines <br />[3] Gross Evaporation equals [I] x [2] <br />[41 Effective Precipitation Rate equals 70° / of total precipitation, based upon NOAA Pueblo Memorial Airport weather station <br />[51 Effective Precipitation
