Mr. Mark A. McLean, P.E. December 5, 2011 DeBeque Pit SWSP Page 4 for a new well permit for the maximum use amounts and maximum exposed ground water surface area anticipated for the future operation of this gravel pit in accordance with § 37 -90- 137(2) and (11), C.R.S. The provisions of § 37 -90- 137(2), C.R.S., prohibit the issuance of a permit for a 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 may be cancelled. 3. Provide the name, address and phone number of the person who will be responsible for the operation of this SWSP to this office, the Division Engineer (Alan Martellaro, 202 Center Driver, P.O. Box 396, Glenwood Springs, Colorado 81601), and the Water Commissioner (Dave Berry, 2754 Compass Drive #175, Grand Junction, CO 81506, 970 - 245 -5884) within 20 days of the receipt of this approval. 4. The total surface area of the groundwater exposed at the DeBeque Pit must not exceed 5.6 acres, which results in a maximum evaporative annual Toss of 17.9 acre -feet per year. 5. The annual water used for dust control at the DeBeque Pit shall not exceed 2.5 acre -feet and the total product mined at the DeBeque Pit site shall not exceed 350,000 tons per year, which results in 10.29 acre -feet of water lost with the mined aggregate. 6. Total consumption at the DeBeque Pit must not exceed these aforementioned amounts unless an amendment is made to this SWSP. 7. Approval of this SWSP is for the purposes as stated herein. This office must first approve any additional uses for which the water may be used. Any future additional historical consumptive use credit given (e.g., agricultural water transfer) for this site must consider all previous credits given. 8. All pumping for dust control shall be measured in a manner acceptable to the division engineer. 9. Replacement water shall be made available to cover all out -of- priority depletions in time, place and amount and shall be made available under the direction and /or approval of the water commissioner. The replacement water that is the subject of this SWSP 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. This SWSP does not allow for offsite water deliveries. All replacement water must be concurrent with depletions in quantity, timing, and locations. 10. Adequate accounting of depletions and replacement must be provided to the Division Engineer in Glenwood Springs (Alan Martellaro, 202 Center Driver, P.O. Box 396, Glenwood Springs, Colorado 81601) and the Water Commissioner (Dave Berry, 2754 Compass Drive #175, Grand Junction, CO 81506, 970 - 245 -5884) 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. The name, address, and phone number of a contact person who will be responsible for the operation and accounting of this plan must be provided on the accounting forms to the division engineer and water commissioner. 12. Dewatering at this site will produce delayed depletions to the stream system. Accordingly, the pit must be continuously dewatered until such time as the pit can be filled by ground water infiltration during a free river period, or an amendment to the SWSP must be requested and approved to include additional replacement water to offset the volume of water required to fill the pit during the
