Mr. Peter Foster, P.E. December 24, 2012 DeBeque Pit (M2011 -054) SWSP Page 4 2. A well permit must be issued for the gravel pit in accordance with § 37 -90- 137(2) and (11), C.R.S. Until a gravel pit well permit is approved, consumptive use and exposure of groundwater on this site is prohibited. 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 will 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, 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 0.78 acres, which results in a maximum evaporative annual loss of 2.47 acre -feet per year. 5. The annual water used for dust control at the DeBeque Pit shall not exceed 7.98 acre -feet and the total product mined at the DeBeque Pit site shall not exceed 75,000 tons per year, which results in 2.21 acre -feet of water lost with the mined aggregate for the first year of operation and shall not exceed 100,000 tons per year, which results in 2.94 acre -feet of water lost with the mined aggregate for the second year of operation. 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, 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
