DEPARTMENT OF NATURAL RESOURCES <br />DIVISION OF WATER RESOURCES <br />Ms. Kimberly Frick <br />Clear Water Solutions <br />8010 S. County Road 5, Ste. 105 <br />Windsor, CO 80528 <br />January 9, 2012 <br />RE: West Farm Pit Substitute Water Supply Plan; M -08 -078 <br />Sections 23 & 28, T22S, R46W, 6 PM <br />Water Division 2, Water District 67 <br />Plan Period: May 1, 2011 through April 30, 2013 <br />Dear Ms. Frick; <br />John W. Hickenlooper <br />Governor <br />Mike King <br />Executive Director <br />Dick Wolfe, P.E. <br />Director /State Engineer <br />This letter is in response to the application submitted January 25, 2011, requesting a <br />renewal of a substitute water supply plan ( "SWSP ") for a sand and gravel pit to be operated by <br />GP Ranches, LLC ( "Applicant ") in accordance with C.R.S. §37 -90- 137(11). The applicant shall <br />be responsible for compliance with this plan, but the State Engineer's Office may also pursue <br />the landowner for eventual compliance. The required fee of $257 (receipt no. 3648894) has <br />been submitted. <br />Plan Operation <br />The West Farm Gravel Pit will be dry mined with the use of dewatering trenches and a <br />discharge settling pond. The length of the dewatering trenches will change throughout mining, <br />but the maximum will occur when two phases are completely mined but reclamation has not yet <br />begun on any given phase. The maximum size of the dewatering trench will be 4,350 feet long <br />and 5 feet wide (0.5 acre). The discharge settling pond will be 50 feet by 100 feet (0.11 acres) <br />for a maximum total exposed surface area of the site during mining to be 0.61 acres. You have <br />estimated that this results in an annual evaporative use of 2.5 acre -feet. <br />Operational uses of groundwater include water retained in the mined material that is <br />removed from the gravel pit site and water used to control dust on haul roads and stockpiles at <br />the West Farm Pit. You have estimated the total annual amount of material to be mined as <br />750,000 tons, at 4% moisture content, which equals a consumptive use value of 22.1 acre -feet. <br />You have also estimated the amount of groundwater to be used for onsite dust control, which is <br />considered to be 100% consumptive, as 6.2 acre -feet annually. The total consumptive use of <br />groundwater would be 28.3 acre -feet. The total on -site use of groundwater would be 30.8 acre - <br />feet. <br />RECEIVED <br />JAN 0 9 2012 <br />Division of Reclamation <br />Mining & Safety <br />Office of the State Engineer <br />1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303 - 866 -3589 <br />http: / /water.state.co.us <br />
