Adapted from EVAPOTRANSPIRATION AND AGRONOMIC RESPONSES IN FORMERLY IRRIGATED MOUNTAIN <br /> MEADOWS, South Park, Colorado, March 1, 1990; Revised September 1, 1991 <br /> 14. The Applicant is in the process of amending DRMS permit no. M-1985-112 to change the final <br /> reclamation to lined storage. If reclamation of the mine site produces a permanent water <br /> surface exposing groundwater to evaporation, an application for a plan for augmentation <br /> must be filed with the Division 1 Water Court at least three (3) years prior to the completion <br /> of mining to include, but not be limited to, long-term evaporation losses. If a lined pond <br /> results after reclamation, replacement of lagged depletions shall continue until there is no <br /> longer an effect on stream flow. Granting of this plan does not imply approval by this office <br /> of any such court application(s). <br /> 15. Dewatering at this site will produce delayed depletions to the stream system. As long as the <br /> pit is continuously dewatered, the water returned to the stream system should be adequate <br /> to offset the depletions, thus dewatering is required to continue during the term of this plan. <br /> Once dewatering at this site ceases, the river will experience a net depletion as the pit <br /> gradually fills. At least three years prior to completion of dewatering, a plan must be <br /> submitted that specifies how the post pumping dewatering depletions (including refilling the <br /> pit) will be replaced, in time, place and amount. Should dewatering cease, this SWSP will <br /> automatically become void until an amendment covering such action is sought and approved. <br /> 16. The monthly volume of water pumped for dewatering operations must be recorded through a <br /> totalizing flow meter and shown on the submitted accounting sheets. <br /> 17. If dewatering of the site is discontinued, the pit would fill creating additional depletions to <br /> the stream system due to increased evaporation. To assure that depletions from ground water <br /> evaporation do not occur in the unforeseen event, or events, that would lead to the <br /> abandonment of the pit, the Applicant has dedicated one share of the Greeley Irrigation <br /> Company (certificate no. 3391) and one share of the New Cache La Poudre Irrigation Company <br /> (certificate no. 4635) as replacement water solely for this SWSP for as long as there are <br /> depletions at this gravel pit site or until such time as another replacement source is obtained. <br /> A copy of the affidavit dated May 30, 2014 is attached to this letter. For the purposes of this <br /> SWSP, this affidavit will be accepted for the dedication of the shares; however, if the State <br /> Engineer determines that a different affidavit or dedication process is necessary to assure <br /> proper dedication of the shares, additional information may be required prior to future SWSP <br /> approvals. <br /> 18. This SWSP may be revoked or modified at any time should it be determined that injury to <br /> other vested water rights has or will occur as a result of this SWSP. Should this SWSP expire <br />
