Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Dick Wolfe, P.E. <br />Director /State Engineer <br />RECEIVE <br />L <br />DIVISION OF RECLAMATION <br />MINING AND SAFETY <br />We have reviewed your letters dated December 17, 2014 and January 21, 2015 requesting <br />approval of a substitute water supply plan ( "SWSP ") on behalf of Loloff Construction, Inc. ( "Loloff" or <br />"Applicant ") to cover depletions caused by an existing gravel pit operation. 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. 3667825) has been <br />received. <br />SWSP Operations <br />The Loloff Pit is a gravel pit operation located in the SE' /4 of the NW1 /4 of Section 4, Township 5 <br />North, Range 65 West of the 6th P.M., in Weld County. Well permit no. 77467 -F has been issued for the site. <br />This SWSP will make replacements to the Cache La Poudre River for depletions resulting from mining <br />operations at the Loloff Pit during the 2015 plan year, and for lagged depletions from past operations at the <br />site. During this plan period, consumptive uses at the Loloff Pit site will include evaporative losses from <br />exposed ground water within the permit boundaries, and operational uses. The replacement sources <br />proposed to be utilized in this SWSP are yield from one share of the Greeley Irrigation Company and a lease <br />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. Depletions <br />are assumed to impact the Cache La Poudre River perpendicular to the Loloff Pit, just above the <br />headgate of the Ogilvy Ditch (WDID 0300937). The pit is proposed to be continuously dewatered during <br />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 exposed in <br />dewatering ditches at the site. Net evaporative depletions were calculated using a gross annual <br />evaporation of 45 inches from the exposed water surface, with a credit of 9.97 inches for effective <br />precipitation. No credit was claimed for ice cover periods. The net depletion of ground water due to <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.watenstate.co.us <br />
