Mr. Peter Foster August 13, 2015 Page 3 of 6 that would lead to abandonment of the pit. Such explanation and/or documentation must be included with the next SWSP renewal request. DEPLETIONS The out -of -priority depletions for the facility during this approval period are expected to be 112.9 acre-feet/year of evaporation from a water surface area not to exceed 39.1 acres, 3.53 acre-feet/year of water lost in product, 3.22 acre-feet/year from concrete batching, and 0.56 acre-feet/year for dust suppression (see Table 2). Total consumptive use from the pit operation is expected to be 120.21 acre-feet/year. It is understood that return flows from gravel washing will be taken as a credit in this plan. Lagged depletions were calculated using the Glover depletion factors decreed for the pit by the Division 7 Water Court in Case No. 07CW104 (see Table 3). At full build -out, after gravel operations have ceased and the de - watered areas are allowed to fill with water, it is anticipated that 39.1 acres of water will be exposed resulting in 112.9 acre-feet of depletions (see Table 1). The operation will be covered by this SWSP and not the decreed augmentation plan. Therefore, water sales will not be allowed under this SWSP. REPLACEMENT The water supply currently decreed as an augmentation source for the Bayfield Facility is the Gosney Alternative Pump Station. The Applicant has a lease agreement, attached, with Gosney Et Sons, Inc. that is effective so long as the Lessee owns the property or until the Lessee terminates the water lease, for an amount of 0.7 cfs. This pump station is decreed to supply up to 1 cfs for augmentation of water use at the Facility. A call is placed on the Pine River generally throughout the irrigation season from May 1 through October 30 by The Pine River Canal. The pump station is located on a tributary to the Pine River in an area that is considered to have water available for appropriation. The water will be delivered to the Bayfield Facility or directly into the Pine River Canal either by ditch or pipeline as directed by the Water Commissioner. Table 3 shows that all out of priority depletions are less than the 0.7 cfs replacement water available, therefore; the Applicant has shown that they have adequate replacement water to cover depletions through the period of this SWSP approval and at full build out with the existing lease. CONDITIONS OF APPROVAL I hereby approve the proposed substitute water supply plan in accordance with Section 37-90- 137(11), C.R.S., subject to the following conditions: This SWSP shall be valid for the period of April 20, 2015 through April 20, 2017, unless otherwise revoked, modified, or superseded by decree. Should an addition SWSP be requested, such renewal request must be submitted to this office with the statutory fee of $257 at least 90 days prior to the expiration date of this plan. 2. The plan for augmentation decreed in case no. 03CW65 may not operate during the life of this SWSP plan, and the replacement water assigned to that plan for augmentation will be utilized under this plan. / OF Cp�C 1313 Sherman Street, Room 821, Denver, CO 80203 P 303.866.3581 F 303.866.3589 www. water. state. co. us
