Eagle Pit SWSP October 5, 2011 Page 5 of 8 well to be located within 600 feet of any existing well, unless the state engineer finds that circumstances so warrant after a hearing held in accordance with the procedural rules in 2CCR402 -5. This hearing may be waived if you are able to obtain statements from the owners of all wells within 600 feet, verifying that they have no objection to your use of the proposed well. Should a new well permit be denied for reasons of 600 foot spacing, or any other legitimate reason, approval of this SWSP will be cancelled. 3. The total surface area of the groundwater exposed at the Eagle Pit site must not exceed 3.5 acres, which results in a maximum evaporative annual loss of 9.4 acre -feet. 4. The annual water used for dust control at the Eagle Pit site shall not exceed 16 acre -feet, the total product mined at the Eagle Pit site shall not exceed 130,000 tons per year, which results in 3.83 acre -feet of water lost with the mined aggregate, and the total amount proposed for domestic uses shall not exceed 0.01 acre -feet. 5. Total consumption at the Eagle Pit site must not exceed these aforementioned amounts unless an amendment is made to this SWSP. 6. Approval of this SWSP is for the purposes as stated herein. This office must first approve any additional uses for the water. Any future additional historical consumptive use credit given (e.g., agricultural water transfer) for this site must consider all previous credits given. 7. All pumping for dust control and domestic purposes shall be measured in a manner acceptable to the division engineer. 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 SWSP, the replacement water must be appurtenant to this site until a plan for augmentation is obtained. All replacement water must be concurrent with depletions in quantity, timing, and locations. 9. 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 with the accounting form to the division engineer and water commissioner. 10. Adequate accounting of depletions and replacements must be provided to the division engineer and the water commissioner on a monthly basis or other interval acceptable to both of them. The accounting form provided with your application is subject to modification and approval by the division engineer. All amounts shall be in acre -feet. 11. 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 Applicant is required to account for and replace any out -of- priority delayed depletions. 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.
