Box 680 <br />Frederick, CO 80530 <br />Re: Bernhardt Pit, Substitute Water Supply Plan (WDID 2528) <br />Division of Reclamation ining and Safety File NO.02002-120 <br />Sections 1 and '12, T4N, R67W, 6t" P.M., Weld County <br />Water Division 1, Water District 2 and 4 <br />Approval Period: January 1, 2010 through December 31, 2010 <br />Contact phone number for Mr. Andy Rodriguez: 303-833-1416 <br />Dear Mr. Rodriguez,: <br />We have received your letter dated December 5, 2009, requesting renewal of the above <br />referenced substitute water supply plan to cover depletions caused by an existing gravel mining <br />operation operated by Hall-Irwin ("Applicant"). The required fee of $257.00 for the renewal of this <br />substitute water supply plan ("SWSP") has been submitted (receipt no. 3643715). The original <br />supply plan was approved January 14, 2004 and the plan was most recently renewed on <br />December 22, 2008. <br />Plan Operation <br />This plan seeks to replace depletions resulting from mining operations at the Bernhardt <br />pit. The depletions that result from the mining operation during this SWSP period are <br />evaporation, concrete batching and dust suppression. The proposed replacement source is <br />excess augmentation credits leased from the Town of Milliken ("Milliken"). The leased water is <br />excess augmentation credits from Milliken's decree, associated with consolidated case nos. <br />2002CW339 and 2005CW59. <br />The mining site has been lined with a bentonite slurry wall. That liner has not yet been <br />approved by the Division Engineer therefore the depletions calculated for this plan assumes <br />that the liner does not exist. <br />An alluvial well has been constructed to provide water for concrete batching. This well <br />was constructed under permit no. 60729-F (WDID 0405678) and is located outside the <br />boundaries of the existing slurry wall. The water withdrawn from the alluvial well is considered <br />100% consumptive. <br />RECEIVED <br />Office of the State Engineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303-866-3581 • Fax: 303-866-3589 FEB 2 4 2010 <br />w w w. w a to r. s to te. co. u s <br />Division of keckiffmion, <br />MiMng and Safety
