Holcim South Platte Combined SWSP June 18, 2024 <br /> Plan IDs 3614, 4773, 3624, 4772, 4616, 3437, 3376, 3650, 3668, 5475, 5829, i± 6243 Page 17 of 26 <br /> Holcim has previously utilized water leased from L.G. Everist, Inc. and stored in the Everist <br /> Star Reservoir (WDID 0303325) as a replacement source in this SWSP. Everist Star Reservoir is part of <br /> the Feit Gravel Pit (M-1977-522), and is primarily located in the SE'/a of the SW'/a and the SW'/a of the <br /> SE'/a of Section 26, Township 6 North, Range 66 West, 6th P.M., adjacent to the Cache la Poudre River. <br /> The slurry wall liner for the Everist Star Reservoir was approved as having been lined to the design <br /> standard referenced in the August 1999 State Engineer Guidelines for Lining Criteria for Gravel Pits in <br /> a letter dated December 16, 2014 (amended March 6, 2015) and it is therefore classified as a lined <br /> reservoir. Deliveries from the Everist Star Reservoir would be to the Cache la Poudre River via a <br /> submersible pump. The headgate for the Greeley No. 3 Ditch is located between the point of <br /> depletion of the W.W. Farms Pit and the Everist Star Reservoir (downstream point of release). During <br /> times when the Greeley No. 3 Canal is calling for water, Holcim is not permitted to use the water <br /> released from the Everist Star Reservoir as a replacement source for depletions from the W.W. Farms <br /> Pit. <br /> Last Chance Ditch Company No. 2 <br /> The Applicant proposes to rely on a ditch-wide analysis of the Last Chance Ditch system <br /> performed by W.W. Wheeler and Associates summarized in a letter report dated April 16, 1990. Prior <br /> to use of these shares as a replacement source, the Applicant must provide a copy of said letter <br /> report to this office for review. Please note that several subsequent change cases involving a change <br /> of shares in the Last Chance Ditch No. 2 found the per-share historical consumptive use to be <br /> significantly lower than the values referenced in the SWSP request. This office reserves the right to <br /> require a new historical consumptive use analysis for Holcim's shares. <br /> Left Hand Ditch Company <br /> The Applicant seeks to rely on the historical consumptive use for the shares determined in <br /> case no. 87CW127. Prior to use of these shares as a replacement source, the Applicant must <br /> demonstrate that the shares have continued to be used in approximately the same way as considered <br /> in case no. 87CW127 since the decree was entered on June 5, 1991 (that there has been no change in <br /> circumstance), or the Applicant must take into account any periods of non-use or undecreed use in <br /> determining the actual historical consumptive use of the shares. <br /> Leggett-Owens Reservoir <br /> Prior to use of these shares as a replacement source, the Applicant must provide a full <br /> historical consumptive use analysis for the subject shares. <br /> Lupton Bottom Seep Ditches No. 1 and No. 2 <br /> Prior to use of these shares as a replacement source, the Applicant must provide a full <br /> historical consumptive use analysis for the subject shares. <br /> Martin Marietta Lease <br /> Holcim has previously utilized water from Martin Marietta Materials, Inc. as a replacement <br /> source in this SWSP. For this SWSP period, the use of leased water from Martin Marietta Materials, <br /> Inc. is not necessary and is not proposed to be utilized. In the future, Holcim may use leased water <br /> from Martin Marietta if a supplemental source of replacement water is needed. <br /> Platte River Power Authority Lease <br />
