The liner approval for the Everist Star Reservoir dated December 16, 2014 wilt not <br />change. The Everist Star Reservoir is primarily located in the SE1 /4 of the SW1 /4 and the SW1 /4 of the SE1 /4 <br />of Section 26, Township 6 North, Range 66 West of the 6`h P.M. Everist Star Reservoir is part of the Feit gravel <br />pit (DRMS M-1977-522). This slurry wall liner leak test commenced August 6, 2014 and concluded on <br />November 10, 2014. Site inspection was performed by our office on September 25, 2014 to review site <br />conditions and the teak test plan. <br />Your revised report dated December 15, 2014 provides the liner summary and leak test result. The test data <br />provided indicates that the „reservoir has been lined to the design standard referenced in the August 1999 <br />State Engineer Guidelines for Lining Criteria for Gravel Pits (1999 SEO Guidelines). Meeting the design <br />standard requires that during reservoir operations all water inflows and outflows for the liner perimeter <br />enclosed area be accounted for on a monthly basis. <br />With this liner approval, the Everist Star Reservoir is now classified as a lined reservoir in accordance with <br />the 1999 SEO Guidelines. Water shalt not be impounded in the reservoir except pursuant to lawful diversions <br />allowed by statute or decree. At all other times, at[ inflow of water into the reservoir from any source, <br />including precipitation and ground water inflows shalt be removed to prevent illegal storage of water. Prior <br />to ANY use of this site, the owner or operator will need to coordinate with Mark Simpson, District 3 Water <br />Commissioner, to review operations, measurement structures, stage -storage curves, and accounting. <br />Please contact me at the number below if you have any questions. <br />Sincerely, <br />a&-010� <br />loana Comaniciu, P.E. <br />Water Resource Engineer <br />ec: Mark Simpson, District 3 Water Commissioner (Mark.
