Adapted from EVAPOTRANSPIRATION AND AGRONOMIC RESPONSES IN FORMERLY IRRIGATED MOUNTAIN MEADOWS, South Park, Colorado, March 1, 1990; Revised September 1, 1991 12. 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. 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 results 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 Teti Pit, North Dahlia Pit, Jeronimus Pit, Platte Valley Pit, F- Street Pit, Brighton Pit, Tucson Pit, Distel Pit. Since mining has ceased at these sites, either the lakes must be Tined or backfilled, or an application for a plan of augmentation for the site must be filed with the water court. In addition all 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. 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. 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 water must cease immediately. 15. In accordance with amendments to §25 -8- 202(7), C.R.S., and "Senate Bill 89 -181 Rules and Regulations" adopted on February 4, 1992, the State Engineer shall determine whether the substitute supply is of a quality to meet requirements of use to senior appropriators. As such, water quality data or analysis may be requested at any time to determine if the water quality is appropriate for downstream water users. 16. The decision of the State Engineer shall have no precedential or evidentiary force, shall not create any presumptions, shift the burden of proof, or serve as a defense in any water court
