C& COLORADO <br /> Division of Water Resources <br /> Department of Natural Resources <br /> July 22, 2020 <br /> Kyle S. Regan, P.G. <br /> Civil Resources, LLC <br /> 323 Fifth Street <br /> P.O. Box 680 <br /> Frederick, CO 80530 <br /> Transmission via email: kyle@civilresources.com <br /> RE: SLURRY WALL LINER APPROVAL-PROVISIONAL <br /> HUNT WATER RESERVOIR NO. 2(WDID 0203951) <br /> CASE NO. 2017CW3215 <br /> HUNT WATER LLC, GRAVEL MINE, DRMS M-2018-027 <br /> SE1/4 SECTION 6, T3N, R66W <br /> WATER DIVISION 1, WATER DISTRICT 2, WELD COUNTY <br /> Dear Mr. Regan: <br /> The purpose of this letter is to provisionally approve the lining of the Hunt Water Reservoir No. 2 ("Reservoir"). This <br /> Reservoir is primarily located in the SE1/4 of Section 6,Township 3 North, Range 66 West of the 61 P.M., and is part of <br /> the Hunt Water LLC Gravel Mine (DRMS M-2018-027). An application for a conditional water right was filed for this <br /> Reservoir in Division 1 Water Court Case No. 2017CW3215. The Reservoir was lined with a soil bentonite slurry wall. <br /> Mining has not commenced within the liner boundary. The slurry wall liner leak test commenced on April 1, 2020 and <br /> concluded on June 30, 2020. A site inspection was performed by our office on March 30, 2020 to review site conditions <br /> and discuss the leak test plan. <br /> Your report dated July 2, 2020 provides the monitoring summary and analysis leak test results. The test data provided <br /> indicates that liner meets the design standard referenced in the August 1999 State Engineer Guidelines for Lining <br /> Criteria for Gravel Pits (1999 SEO Guidelines). Meeting the design standard requires that during the Reservoir <br /> operations all water inflows and outflows for the liner perimeter enclosed area be accounted for on a monthly basis. <br /> This liner approval is applicable only during mining operations at the site and does not classify the structure as a reservoir <br /> capable of water storage. However, for the remainder of mining operations, any accumulated water within the liner <br /> boundary is classified as trapped native ground water. The trapped native ground water may be removed from within <br /> the lined area and returned to the stream system through surface flow or ground water recharge without the need for <br /> replacement so long as the operator does not put the water to beneficial use. All native trapped ground water remaining <br /> that is put to beneficial use(except for the water removed in product)must be replaced by the operator. All inflow of <br /> water into the liner boundary from any source,including precipitation and ground water inflows shall be removed by the <br /> pit operator so as not to cause out-of-priority storage. In order for the liner to be approved for water storage the <br /> operator must perform a final leak test once mining is complete and the site is at final grade. The final leak test will <br /> be allowed to have a modified duration of 30 to 45 days as long as the liner continues to satisfactorily operate during <br /> mining operations. <br /> Please contact me at 303-866-3581 x8246 if you have any questions. <br /> Sincerely, <br /> aZel'G <br /> loana Comaniciu, P.E. <br /> Water Resource Engineer <br /> Ec: Jorge Vidal, District 2 Water Commissioner(Jorge.Vidat@state.co.us) <br /> Louis Flink, Diversion Records Coordinator(Louis.Flink@state.co.us) <br /> Andy Rodriguez (andv@civilresources.com) <br /> David Hunt (david@huntfeedyard.com) <br /> WDID File (0203951) <br /> OF cots <br /> 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 www.colorado.gov/water <br /> Jared S.
