The required fee of $1,593 for <br />the substitute water, supply plan has been paid. <br />Plan Operations <br />This plan seeks to replace depletions resulting from the mining at the Reese-Logan Pit <br />("Gravel Pit")-WDID 6403009. The depletions that result from the existing wet-mining operation <br />include evaporation, dust control, and water lost in mined product. The mine is located in the <br />SE '/ of Section 26, Township 7 North, Range 53 West of the 6th P.M. Mining operations at the <br />Reese-Logan Pit began in 1996, resulting in a ground water pond. You have estimated the <br />exposed ground water surface area to be 3.7 acres. based on a 2009 aerial photo. The <br />proposed replacement source is excess recharge accretion credits from the North Sterling <br />Irrigation District ("NSID"). <br />Depletions <br />For the September 2009 through December 2009 period, evaporation was based on an <br />exposed ground water surface area of 3.7 acres. The monthly evaporative losses are shown in <br />the attached Table 1. Operational losses for the September 2009 through December 2009 <br />period only include 0.09 acre-feet per month used for dust control. For the September 2009 <br />through December 2009 period, you have indicated the lagged operational and evaporation <br />losses total 4.44 acre-feet and the amount of leased replacement water from NSID totals 5.58 <br />acre-feet for this same period. <br />Staa to E <br />Office of the ngineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303-866-3581 • Fax: 303-866-3589 <br />www.waterstate.co.us
