Michelle'L. Hatcher 8/13/2007 Pages water must be concurrent with depletions in quantity, timing, and locations. The use of replacement water must be in compliance with alt agreements with the providers of replacement water. 10. Dewatering at the pits will produce delayed depletions to the stream system. As long as the pit is continuously dewatered, the water returned to the stream system should be adequate to offset the depletions. However, once dewatering at the site ceases, the delayed depletions must be addressed. At least three years prior to completion of mining, a plan must be submitted that '. specifies how the post pumping dewatering depletions will be replaced in time, place and amount. i 11. Approval of this plan is for the purposes as stated herein. This office must first approve any additional uses for which the water may be used. 12. The approval of this substitute water supply plan does not relieve the Applicant and/or landowner of the requirement to obtain a Water Court decree approving a permanent plan for augmentation or mitigation to ensure the permanent replacement of all depletions, including long-term evaporation losses and lagged depletions after gravel mining operations have ceased. If reclamation of the mine sites will produce 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 and lagged depletions. If a lined pond resuks after ~ reclamation, replacement of lagged depletions shall continue until there is no longer an effect on stream flow. According to the plan mining has ceased at the Fort Lupton Pit, Tanabe Pit and Dunes Development Property. Since mining has ceased at these sites, either the lakes must be lined or backfilled, or an application for a plan of augmentation for the site must be filed with the water court. !n addition al! lagged depletions shall continue to be replaced under a SWSP until there is no longer an effect on stream flow or a court approved augmentation plan is approved by the water court. Prior to further plan approvals the applicant must demonstrate that the sites are being lined or backfilled or that an application for a plan of augmentation has been filed with the water court. 13. The name, address, and phone number of a contact person who will be responsible for the operation and accounting of this plan must be provided to ~ the Water Commissioner(s) and the Division Engineer. 14. This plan may be revoked or modified at any time should it be determined that injury to other vested water rights has or will occur as a result of the operation of this plan. 15. Should this substitute water supply plan expire without renewal or be revoked prior to adjudication of a permanent plan for augmentation, all use of ground i water must cease immediately.
