DIVISION OF WATER RESOURCES DEPARTMENT OF NATURAL RESOURCES lyls. Michelle L. Hatcher tear Water Solutions, Inc. 8010 S. County Road 5, Suite 105 Windsor, CO 80528 April 10, 2013 Re: Hokestra Substitute Water Supply Plan (WDID 0502521) Hokestra Pit, DRMS Permit No.MVl -1980 -149 (WDID 0503006) Section 2, T2N, and Section 35, T3N, R68W, 6 P.M. Water Division 1, Water District 5, Weld County Approval Period: April 1, 2013 through March 31, 2014 Contact Phone Number for Ms. Hatcher: 970 - 223 -3706 Dear Ms. Hatcher: John W. Hickenlooper Governor Mike King Executive Director Dick Wolfe, P.E. Director /State Engineer RECEIVED `APR 1 12013 Division of Reclamatio Mining & Safety We have reviewed your letter dated February 15, 2013, requesting renewal of the above referenced substitute water supply plan to cover depletions caused by an existing mining operation. The required fee of $257.00 for the renewal of this substitute supply plan has been submitted (receipt no. 3654109). The original supply plan was approved on December 3, 2001 and was most recently renewed on July 30, 2012 for operations through March 31, 2013. Plan Operation This plan seeks to replace depletions resulting from mining operations at the Hokestra gravel pit (well permit no. 63693 -F), owned and operated by Weld County ( "County "). The County does not intend to operate the Hokestra Pit for mining during this SWSP period, therefore the only depletions at the site during this SWSP period will be evaporation from exposed ground water and water used for irrigation at Weld County's Southwest Service Center. The proposed replacement sources are 3.75 Rural Ditch shares owned by Weld County and storage of excess credits from those shares in Varra Companies' lined 112 Reservoir (WDID 0504001), In accordance with the letter dated April 30, 2010 from the Colorado Division of Reclamation, Mining, and Safety ( "DRMS "), all sand and gravel mining operators must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the protection of water resources. The April 30, 2010 letter from DRMS requires that you provide information to DRMS to demonstrate you can replace long term injurious stream depletions that result from mining related exposure of ground water. Pursuant to approach number 3, the County is completing a slurry wall to eliminate the long term evaporation from the site. No bond has been posted for this work because a financial warranty is not required for a county. Further the County will pursue an augmentation plan for the remaining unlined areas using their 3.5 Rural Ditch shares.
