<br />Evaporation Consump Use
<br />Table 3 Revised January 10, 2013
<br />Martin Marietta Materials
<br />Riverbend East Demands Table
<br />Mining Consumptive Use
<br />Notes.
<br />(1) Monthly percentages determined in SB89 -120 for elevations below 6,500 feet
<br />(2) NOAA Technical Report NWS 33, Evaporation Atlas for the Contiguous 48 United States notes a total annual gross evaporation of 45 0 inches
<br />(3) Gross evaporation = (2) x total exposed surface area which is equal to 28 acres
<br />(4) Based upon the Western Regional Climate Center Station for Brighton, CO (050950) for the time penod 1973 -2012
<br />(5) Effective precipitation = (4) x 0 7/12
<br />(6) Net lake evaporation = (2) - (5)
<br />(7) Evaporative consumptive use = (6) x total exposed surface area which is equal to 28 acres
<br />(8) Aggregate production as projected by Martin Marietta Materials for WY2013 and WY2014 November values reflect actual production which occurred in November
<br />(9) Water consumed by the washed aggregate is equal to 4% of the total volume of mined material as defined by SB 89 -120
<br />(10) Water used for dust control based on MMM estimates. November values reflect actual dust control water used in November
<br />(11) Operational Consumptive Use = (9) + (10)
<br />(12) Total consumptive use = (7) + (11)
<br />(13) Reflects lagged depletions due to evaporation, operational uses and past mining activities at the site based on Glover analysis using parameters noted in Table 7
