Mr. Jared Dains, E.I. November 2, 2010 Page 5of7 water commissioner. The release of replacement water may be aggregated to maximize beneficial use. The water commissioner and/or the division engineer shall determine the rate and timing of an aggregated release. The Applicant is required to coordinate with the water commissioner the delivery location of replacement water to ensure out-of-priority depletions are adequately replaced to prevent injury to other water rights. Conveyance loss for delivery of augmentation water is subject to assessment and modification as determined by the water commissioner or division engineer. 9. According to the Applicant, the distance from the surface of the exposed ground water area to the Cache La Poudre River was measured based on the down gradient extent of the exposed ground water surface (nearest point). For purposes of this SWSP, the method used to measure the distance to estimate the lagged depletions will be accepted, however any future SWSP must measure the distance from the exposed ground water surface area to the Cache La Poudre River based on the centroid of the exposed ground water surface. 10. 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. A copy of this approval letter should be recorded with the county clerk and recorder. All replacement water must be concurrent with depletions in quantity, timing, and location. 11. The name, address, and phone number of the contact person who will be responsible for the operation and accounting of this plan must be provided on the accounting forms submitted to the division engineer and the water commissioner. 12. Adequate accounting of depletions and replacements must be provided to the division engineer in Greeley (Div 1Accounting Astate.co.us) and the water commissioner (Geor4e.Varra(a-state.co.us) on a monthly basis or other interval acceptable to both of them. The accounting form provided with your application is subject to modification and approval by the division engineer. All amounts shall be in acre-feet. In addition, the Applicant shall submit a report from the Graham Drainage Ditch Company that shall include an accounting of all of the Graham Seepage & Drainage Canal water controlled by the Graham Drainage Ditch Company, showing the total volume of water under its control and the amount committed to each of the recipients of the water. 13. All pumping for dust control purposes shall be measured in a manner acceptable to the division engineer. Permanent records of all diversions must be maintained by the well owner (recorded at least monthly) and submitted to the division engineer and water commissioner as required by the terms of this plan. 14. If reclamation of the mine site produces a permanent water surface exposing groundwater to evaporation, an application for a plan for augmentation must be filed with the Division 1 Water Court at least three (3) years prior to the completion of mining to include, but not be limited to, long-term evaporation losses. If a lined pond results after reclamation, replacement of lagged depletions shall continue until there is no longer an effect on stream flow. Granting of this plan does not imply approval by this office of any such court application(s). 15. Dewatering is not expected to occur at this site during the SWSP approval period. However, in the event that dewatering will occur at the site during the SWSP approval period, note that as long as the pits are continuously dewatered, the water returned to the stream system should be adequate to offset the depletions. Once dewatering at this site ceases, the river will experience a net depletion as the pit gradually fills. At least three years prior to completion of
