Mr. Andy Rodriguez, P.E Page 5 of 6 Shores SWSP November 26, 2012 9. 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. 10. Adequate accounting of depletions and replacements must be provided to the division engineer in Greeley (Div1Accountinq(a)state.co.us) and the water commissioner (Shera Sumerford at Shera.Sumerfordstate.co.us) on a monthly basis. The accounting form provided with your application is subject to modification and approval by the division engineer. All submitted accounting shall conform to the Administration Protocol "Augmentation Plan Accounting, Division One - South Platte River" (attached). In addition, the applicant shall verify that the entities making replacement are identifying this use on their accounting submitted to our office. For the period of this plan, that entity is the City of Aurora (WDID 0802593 — Aurora Reuse). 11. The approval of this substitute water supply plan does not relieve the Applicant and /or the 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 Tong -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 from mining and dewatering shall continue until there is no longer an effect on stream flow. 12. 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. If dewatering at the site ceases, the delayed depletions must be addressed. 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 the pit) will be replaced, in time, place and amount. Regardless if accretion credits are sought, the Applicant is required to meter all dewatering operations and report monthly meter reads on submitted accounting. 13. To assure that depletions from groundwater evaporation do not occur in the unforeseen event, or events, that would lead to the abandonment of the pit, a bond for $1,607,800 through DRMS for reclamation of the pit has been obtained. Therefore, in case of abandonment the bond can finance the completion of the lining of the pit or the backfilling, thus preventing depletions to the stream system. 14. This substitute water supply plan may be revoked or modified at any time should it be determined that injury to other water rights has or will occur as a result 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 excavation of product from below the water table, and all other use of water at the pit, 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.
