East 8th Street Pit SWSP Page 4 of 5 October 29, 2015 7. Approval of this plan is for the purposes as stated herein. This office must first approve any additional uses for the water. 8. 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. 9. All releases of replacement water must be sufficient to cover all out -of -priority depletions in time, place, and amount and must be made under the direction and/or the approval of the 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. 10. Conveyance loss for delivery of augmentation water is subject to assessment and modification as determined by the water commissioner or division engineer. 11. Adequate accounting of depletions and replacements must be provided to the division engineer in Greeley (DivlAccounting@state.co.us) and the water commissioner (Mark Simpson at Mark.Simpson@state.co.us) on a monthly basis or other interval acceptable to both of them. Submitted accounting shall conform to the Administration Protocol "Augmentation Plan Accounting, Division One - South Platte Basin" (attached). In addition, it is the applicant's responsibility to verify that the entities making replacements are identifying this use on their accounting submitted to our office. For the period of this plan, that entity is City of Greeley (WDID 0303330 - GLIC Accounting). 12. The name, mailing address, and phone number of the contact person who will be responsible for operation and accounting of this plan must be provided on the accounting forms to the division engineer and water commissioner. 13. The approval of this SWSP 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 site 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. 14. 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 attributable to the dewatering operation. Should there be a delay between the cessation of dewatering at the west cell and the commencement of dewatering at the east cell, the lagged dewatering depletions impacting the stream during that time period must be replaced. The Applicant is required to notify the water commissioner when dewatering ceases at the west cell and when dewatering commences at the east cell. The operator shall equip the dewatering operations with a totalizing flow meter and report monthly meter readings which will be used to determine the post -pumping depletions when dewatering ceases. Once dewatering at the site ceases, the delayed depletions must be addressed. Accordingly, dewatering is required to continue during the term of this approval. At least three years prior to completion of dewatering, a plan must be submitted that specifies how the post pumping dewatering depletions (including refilling of
