Ms. Jennifer S. Lindahl Page 5 of 9 <br />June 28, 2018 <br /> <br /> <br />The mine site total projected lagged depletions are shown in Table 3, column 1 and totals 131.0 <br />acre-feet over the SWSP amendment period. <br /> <br />Replacements <br />The proposed source of replacement water for this SWSP is fully consumable water leased from <br />the City of Aurora (“Aurora”). The Applicant previously provided a copy of the lease agreement <br />with Aurora for the period of April 30, 2016 through December 31, 2017. An extension of the <br />lease with Aurora for 2018 was provided to this office on October 4, 2017 and a copy is attached <br />to this letter. Water leased from Aurora would be released from the Robert W. Hite Treatment <br />Facility (a/k/a Metro Wastewater Treatment Plant (MWWTP)) (WDID 0200700) in the SW1/4 of <br />the SW1/4 of Section 1, Township 3 South, Range 68 West of the 6th P.M. A transit loss of 0.5 <br />percent per mile is currently assessed from April through September and a transit loss of 0.25 <br />percent per mile is currently assessed during October through March for delivery of water down <br />the South Platte River. Such transit losses are subject to modification by the division engineer. <br />The MWWTP is located approximately 25 miles upstream of the confluence of the South Platte <br />River and Big Dry Creek where the mining depletions will accrue to the river, therefore the total <br />transit loss will be 12.5 percent during the irrigation season and 6.25 percent during the non- <br />irrigation season. Replacement supplies from Aurora include transit loss, so all Morton Lakes and <br />Holton Lakes depletions are fully replaced at the point of depletions through December 31, 2018 <br />(Table 3). <br />
