Loloff Pit SWSP February 25, 2015 Page 6 of 7 14. The Applicant is in the process of amending permit no. M- 1985 -112 to change the final reclamation to lined storage. 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 shalt 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 at this site 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, thus dewatering is required to continue during the term of this plan. 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 dewatering, a plan must be submitted that specifies how the post pumping dewatering depletions (including refilling the pit) will be replaced, in time, place and amount. Should dewatering cease, this SWSP will automatically become void until an amendment covering such action is sought and approved. 16. The monthly volume of water pumped for dewatering operations must be recorded through a totalizing flow meter and shown on the submitted accounting sheets. 17. If dewatering of the site is discontinued, the pit would fill creating additional depletions to the stream system due to increased evaporation. To assure that depletions from ground water evaporation do not occur in the unforeseen event, or events, that would lead to the abandonment of the pit, the Applicant has dedicated one share of the Greeley Irrigation Company (certificate no. 3391) and one share of the New Cache La Poudre Irrigation Company (certificate no. 4635) as replacement water solely for this SWSP for as long as there are depletions at this gravel pit site or until such time as another replacement source is obtained. A copy of the affidavit dated May 30, 2014 is attached to this letter. For the purposes of this SWSP, this affidavit will be accepted for the dedication of the shares; however, if the State Engineer determines that a different affidavit or dedication process is necessary to assure proper dedication of the shares, additional information may be required prior to future SWSP approvals. 18. This SWSP 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 this SWSP. Should this SWSP expire without renewal or be revoked prior to adjudication of a permanent plan for augmentation, all use of ground water must cease immediately. 19. In accordance with amendments to S 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. 20. 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 pending water court case or any other legal action that may be initiated concerning this plan. This decision shall not bind the state engineer to act in a similar manner in any other applications involving other plans, or in any proposed renewal of this plan, and shall not imply concurrence with any findings of fact or conclusions of law contained herein, or with the engineering methodologies used by the Applicant.
