t Mr. Jared Dains, P.E. Page 6 of 9 May 7, 2015 site or until such time as another replacement source is obtained. A copy of the affidavit is attached to this letter. As evidenced by the need for additional leases covering the irrigation and non -irrigation seasons during this plan period, the 3.0 GIC shares are not sufficient by themselves to provide long term augmentation water for the current 71.8 acres of exposed ground water, nor for the final reclamation plan of 95 acres of exposed ground water. According to previous SWSP requests, the Applicant is in the process of acquiring an additional 5.5 GIC shares or more, for a total of at least 8.5 GIC shares. Based on information in the DRMS files, the Applicant has purchased and dedicated 2.5 shares of augmentation water. The proposed 8.5 shares are expected to provide approximately 87.64 acre-feet of consumptive use credit per year (10.31 acre-feet per share x 8.5 shares). Although this amount exceeds the depletions associated with the current 71.8 acres of exposed ground water at the site, additional replacement water will need to be obtained to replace depletions from the 95 acres of exposed ground water proposed to remain at the site after final reclamation. According to information in the DRMS files, if the Applicant is not able to purchase the required water shares, the DRMS will calculate the required financial warranty to backfill the exposed ground water areas not covered by the dedicated shares. SWSP Conditions of Approval hereby approve the proposed substitute water supply plan in accordance with S 37-90- 137(11), C.R.S. subject to the following conditions: 1. This plan shall be valid for the period of April 1, 2015 through March 31, 2016 unless otherwise revoked or modified. If this plan will not be made absolute by a water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutory fee of $257 prior to the expiration date but no later than February 1, 2016. 2. A well permit has been obtained for the current use and exposed pond surface area of the gravel pit in accordance with S 37-90-137(2) and (11), C.R.S., permit no. 74638-F. 3. The total surface area of the ground water exposed at the Greeley Pit after December 31, 1980 must not exceed 31.8 acres, which results in an annual evaporative loss of 87.19 acre- feet (assuming ice cover during the months of December and January). 4. The annual amount of water used at the Greeley Pit for dust control shall not exceed 1.00 acre-feet. 5. Total consumption at the Greeley Pit must not exceed these aforementioned amounts unless an amendment is made to this plan. 6. Approval of this plan is for the purposes as stated herein. Any additional uses of the water will be allowed only if a new SWSP is approved for those additional uses. 7. Applicant shall replace the net evaporative depletions from the exposed ground water surface area that may occur during the assumed ice covered period (December and January) for any time that the exposed ground water in the pit is not completely covered by ice. 8. The replacement water that is the subject of this plan cannot be sold or leased to any other entity. As a condition of subsequent renewals of this substitute water supply plan, the replacement water must be appurtenant to this site until a plan for augmentation is obtained. 9. The Applicant has proposed to use for augmentation, water available from any other source legally available for augmentation and which can be provided in the amount, at the time, and at the location required to replace out of priority depletions from the Bucklen Pit. Additional sources of replacement water in this SWSP may only be used if the Applicant complies with
