Ryan Stitt Denver Water NRC SWSP November 27, 2012 Page 7 of 8 4. The total area of pond surface exposed in Hazeltine Reservoir shall not exceed 17.63 acres. Should the total surface area exposed exceed those amounts, an amendment will need to be filed with this office. 5. Denver Water may use the mounding drain water for gravel pit operations including dust control, fire control, and a concrete batch plant. All water delivered to the pre -81 pond will be metered and must be considered 100% consumptive with replacements made at any time the site is subject to a call on the river. This SWSP does not authorize any water lost with mined product and other than clean up of stockpile within the Hazeltine Reservoir, there is not mining projected to occur in this SWSP approval period. 6. Approval of this plan is for the purposes as stated herein. Any additional uses of this water must first be approved by this office. Any future additional historic consumptive use credit given (e.g., agricultural water transfer) for this site must consider all previous credits given. 7. 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. 8. The name, address, and phone number of the contact person who will be responsible for the operation and accounting of this plan must be provided on the accounting forms submitted to the division engineer and the water commissioner. 9. All diversions shall be measured in a manner acceptable to the Division Engineer. The Applicant shall install and maintain such measuring devices as required by the Division Engineer for operation of this SWSP. In addition, the applicant shall maintain daily records of all diversions, replacements, and the amount of water used for each particular purpose. The applicant shall provide a report of these records to the division engineer and the water commissioner on a monthly basis on a form approved by them. The accounting must be submitted to the division engineer in Greeley (Div1Accountingtc7i state.co.us) and the water commissioner (Bill Schneider at William .Schneider(c�state.co.us) within 30 calendar days of the end of the month for which the accounting is being made. All amounts shall be in acre -feet. All submitted accounting shall conform to the Administrative Protocol "Augmentation Plan Accounting, Division One — South Platte River" (attached). In addition, Denver Water shall ensure all replacement water released to the river on behalf of this SWSP is included in Denver Water's municipal accounting. 10. 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 site will produce a permanent water surface exposing post -80 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.
