DEPARTMENT OF NATURAL RESOURCES DIVISION OF WATER RESOURCES Ig76`� March 31, 2014 Mr. Jared Dains, E.I. Applegate Group, Inc. 1490 West 121" Avenue, Suite 100 Denver, CO 80234 Re: Greeley Pit Substitute Water Supply Plan_..(WDID 0302545) Greeley Pit, DRMS Permit No. M- 1977 -151 (WDID 0303034) Section 36, T6N, R66W and Section 31, fi6N, R65W, 6t" P.M. Water Division 1, Water District 3, Weld County Approval Period: April 1, 2014 through March 31, 2015 Contact Phone Number for Mr. Dains: 303 - 452 -6611 Dear Mr. Dains: John W. Hickenlooper Governor Mike King Executive Director Dick Wolfe, P.E. Director /State Engineer APR 0 2 2014 Division of Reclamation, Mining & Safety We have received your letter dated March 3, 2014, requesting renewal of the above - referenced substitute water supply plan ( "SWSP ") on behalf of R.M. Hiner Construction Co., Inc. ( "Hiner" or "Applicant"). This SWSP is requested in accordance with § 37 -90- 137(11), C.R.S., to cover depletions caused by an existing gravel mining operation. The required fee of $257.00 for the renewal of this substitute water supply plan has been submitted (receipt no. 3663828). The most recent substitute water supply plan was approved on March 27, 2013 for operations through March 31, 2014. SWSP Operations The Greeley Pit (well permit no. 74638 -F, WDID 0303034) is located in the NE% of Section 36, Township 6 North, Range 66 West and the NW% of Section 31, Township 6 North, Range 65 West of the 6t" P.M., as shown on the attached Figure 1 (Vicinity Map). Hiner does not propose to mine or dewater the pit during this plan period. Out -of- priority depletions from the Greeley Pit will be replaced with a combination of Hiner's ownership of 3.0 shares in the Greeley Irrigation Company and leases with the Graham Ditch Company and the Platte River Power Authority. Depletions During this plan period consumptive use at the Greeley Pit will consist of evaporation from exposed surface area and water used for dust control. Net evaporative depletions were calculated using a gross annual evaporation of 45 inches from the exposed water surface, with a credit of 9.81 inches for effective precipitation. The current exposed surface area at this site is 71.8 acres. Pursuant to § 37- 90- 137(11)(b), C.R.S. and 2009CW49, a gravel pit operator or property owner does not need to replace depletions that occur due to evaporation from ground water exposed prior to January 1, 1981 as a result of open mining of sand and gravel ( "pre -81 areas "), regardless of whether mining continued after December 31, 1980. This SWSP recognizes a total of 40.2 acres at the Greeley Pit as being pre -81 exposure. Accordingly, for the 71.8 acres of ground water currently exposed at the Greeley Pit, replacement of evaporative depletions is only required from the 31.6 acres exposed after December 31, 1980. Per our "General Guidelines for Substitute Water Supply Plans for Sand and Gravel Pits" updated April 1, 2011, pre -81 areas are tied to Office of the State Engineer 1313 Sherman Street, Suite 818 • Denver, CO 80203 • Phone: 303 - 866 -3581 • Fax: 303 -866 -3589 www. w a to r. state. co m s
