("Loloff" or "Applicant") to cover <br /> depletions at an existing gravel pit operation known as the Loloff Pit. This site was previously <br /> covered under the combined SWSP for Aggregate Industries ("Al"); however a separate SWSP was <br /> obtained by Loloff for the site in 2008. The required renewal fee of $257 (receipt no. 3672595) has <br /> been received. <br /> SWSP Operations <br /> The Loloff Pit is a gravel pit operation located in the SEA of the NW% of Section 4, Township 5 <br /> North, Range 65 West of the 6th P.M., in Weld County. Amended well permit no. 77467-F has been <br /> issued for the site. This SWSP will make replacements to the Cache La Poudre River for depletions <br /> resulting from mining operations at the Loloff Pit during the 2016 plan year, and for lagged depletions <br /> from past operations at the site. During this plan period, consumptive uses at the Loloff Pit site will <br /> include evaporative losses from exposed ground water within the permit boundaries, and operational <br /> uses. The replacement sources proposed to be utilized in this SWSP are yield from one share of the <br /> Greeley Irrigation Company and a lease of wholly consumable supplies from the City of Greeley. <br /> Depletions <br /> Consumptive use at the Loloff Pit site will include evaporative and operational losses. <br /> Depletions are assumed to impact the Cache La Poudre River perpendicular to the Loloff Pit, just <br /> above the headgate of the Ogilvy Ditch (WDID 0300937). The pit is proposed to be continuously <br /> dewatered during this plan period to allow dry mining. <br /> Based on a November 21, 2014 survey, there are a total of 1.52 acres of ground water <br /> exposed in dewatering ditches at the site. Net evaporative depletions were calculated using a gross <br /> annual evaporation of 45 inches from the exposed water surface, with a credit of 9.97 inches for <br /> effective precipitation. No credit was claimed for ice cover periods. The net depletion of ground <br /> water due to evaporation of exposed ground water surface was calculated to be 4.43 acre-feet for <br /> Office of the State Engineer <br /> 1313 Sherman Street, Suite 818 •Denver, CO 80203•Phone:303-866-3581 • Fax:303-866-3589 <br /> www.water.state.co.us <br />
