<br />DEPARTMENT OF NATURAL RESOURCES maz? <br />DIVISION OF WATER RESOURCES <br />November 23, 2010 <br />Mr. Jared Dains <br />.Applegate Groy, Inc. <br />1499 West 120 Avenue, Suite 200 <br />Denver, Colorado 80234-2759 <br />Bill Ritter, Jr. <br />Mike Kins <br />Bxecutive?Diredor <br />Dick Wolfe, P.B. <br />Direct r/State Engineer <br />RE: Substitute Water Supply Plan, Bucklen Pit, DRMS-M-82-131 (WDID 0302538) <br />Section 36, T6N, R66W, 6th P.M. and Section 31, T6N, R65W, 6th P.M. <br />Water Division 1, Water District 3, Weld County <br />Approval Period: November 1, 2010 through October 31, 2011 <br />Contact Phone Number for Mr. Dains: 303-452-6611 <br />Dear Mr. Dains: <br />We have reviewed your letter of September 15,.2010 requesting renewal of the above <br />referenced substitute water supply plan ("SWSP") for an existing sand and gravel operation. The <br />required fee of $257.00 for the renewal of this SWSP has been submitted (receipt no. 3647365). The <br />original SWSP was approved on September 15, 1993 and it was most recently approved in a letter <br />dated February 22, 2010. <br />SWSP Operations <br />This plan seeks to replace depletions resulting from mining operations at the Bucklen Pit <br />(WDID 0303032). The depletions from the mining operation are evaporation, water lost in the <br />mined product, and dust suppression. The mine is located in Weld County in portions of Section <br />36, Township 6 North, Range 66 West, and portions of Section 31, Township 6 North, Range 65 <br />West. This SWSP will provide for the replacement of the projected depletions of 54.39 acre-feet <br />from November 1, 2010 through October 31, 2011. The replacements will be made using five <br />shares of the Greeley Irrigation Company and leased water from the City of Greeley and the Platte <br />River Power Authority. <br />Depletions <br />The anticipated net depletion for this plan is 54.39 acre-feet per year. Currently there are.17.81 <br />acres exposed at the Bucklen Pit site. The pit is presently being dewatered to allow for dry mining. The <br />majority of the current exposed surface area consists of a large pond of 17.65 acres and the additional <br />0.16 acres of exposed surface area consists of the dewatering trenches. Based on the information from <br />the previous SWSP, 5.27 acres of ground water was exposed within the reclamation permit boundary <br />prior to January 1, 1981. You indicated that the 5.27 acres exposed within the reclamation permit <br />boundary prior to January 1, 1981 was backfilled. Therefore, this SWSP does not seek to take credit <br />from the surface area that was exposed prior to January 1, 1981 since the pre-81 excavated area no <br />longer includes exposed ground water. The Bucklen Pit is located within 100 feet from the Cache La <br />Poudre River, therefore the timi g of tthe stream depletions was assumed to be instantaneous. <br />Office of the State Engineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 a Phone: 303-866-3581 • Fax: 303-866-3589 <br />www.water.state.co.us <br />DEC 01 2010 <br />Division of Recisination, <br />Mk" wo 8d"
