Andy Rodriguez Bernhardt SWSP January 8, 2013 Page 3 4. The annual amount of water used at the operation shall not exceed 3.33 acre -feet for dust control and the amount used for concrete production shall not exceed 1.23 acre -feet used in the production of 10,000 tons of concrete. 5. Total consumption at the Bernhard Pit must not exceed the aforementioned amounts unless an amendment is made to this plan. 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. 7. 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 8. All releases of replacement water must be sufficient to cover all out of priority depletions and be made under the direction and /or approval of the water commissioner. The replacement may be aggregated to maximize beneficial use. The water commissioner and /or division engineer shall determine the rate and timing of an aggregated release. 9. Water shall not be impounded in the slurry wall reservoir except pursuant to lawful diversions allowed by statute or decree. At all other times, all inflow of water into the reservoir from any source, including precipitation and ground water inflows, shall be removed by the applicant. The water may be removed from within the lined area and returned to the stream system through surface flow or ground water recharge without need for replacement, so long as the operator does not put the water to beneficial use. 10. 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. 11. Adequate accounting of depletions and replacements must be provided to the division engineer in Greeley (Div1Accounting a state.co.us) and the water commissioners (Jason Smith at Jason. Smith2(a)-state.co.us and William Schneider at William. SchneiderCo)-state. 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 Town of Milliken ( "Milliken ") has submitted a report to the Division Engineer that includes an accounting of all replacement water controlled by Milliken, showing the total volume of water under its control and the amount committed to each of the recipients of the water, including the water committed to this plan. 12. 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 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. 13. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of Reclamation, Mining, and Safety ( "DRMS "), all sand and gravel mining operators must comply
