Jared Dains South Platte Combined Replacement Plan January 9, 2013 Page 15 3. The total area of pond surface exposed for each of the pits shall not exceed those values listed in Table A of this approval. Should the total surface area exposed exceed those amounts, an amendment will need to be filed with this office. The total amount of ground water to be consumed at the gravel mining operations shall not exceed the values listed in Table C of this approval. Should the amount of ground water to be appropriated from each of the pits exceed the values listed in Table C, an amendment will need to be filed with this office. 4. Dewatering at the pits will produce delayed depletions to the stream system. At least three years prior to completion of mining, 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. 5. Prior to claiming any credit for the water returned to the stream system from dewatering in excess of lagged dewatering depletions (a net accretion), the applicant must install a totalizing flow meter that accurately measures the quantity of water being pumped and returned to the stream system via dewatering operations and account on a real time basis for the actual dewatering depletions and accretions. No net accretion credits are sought by the Applicant for this approval period. 6. The installation of any device used for measuring replacement water in this plan must be inspected by a Division 1 hydrographer. Furthermore, the exact location of all return structures utilized in this plan must be provided to the Division Engineer and Water Commissioner in order to allow for inspections of the structures. Finally, all charts or other output data associated with each measuring device utilized in this plan must be provided in a timely manner acceptable to the Water Commissioner. 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. 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 (Div1Accountinq(a state.co.us) and the water commissioners William Schneider (William.Schneiderstate.co.us), Mark Simpson (Mark.Simpson @state.co.us), Shera Sumerford (Shera.Sumerford@state.co.us), and Bob Carlson (Bob.Carlsonstate.co.us) within 30 calendar days of the end of the month for which the accounting is being made.

For this plan those entities are the City of Westminster, City of Thornton, City of Greeley, and Centennial Water and Sanitation District. 8. 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(s). The release of replacement water may be aggregated to maximize beneficial use. The water commissioner(s) and /or the division engineer shall determine the rate and timing of an aggregated release. 9. 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
