Mr. Mark A. McLean, P.E. DeBeque Pit SWSP April 12, 2013 Page 4 months of May through September. The excess credits total 6.2 acre -feet for this period. According to the water balance table provided for this SWSP (attached Table 4), these excess consumptive use credits will now be utilized to replace the additional depletions approved under this SWSP. Approval by this SWSP to use these excess consumptive use credits is limited to replacing depletions resulting from the gravel pit mining operation at the DeBeque Pit. Any request to utilize these excess credits at a different location, or for a different purpose may require a subsequent change of water right for the Larkin Ditch and may require a re- quantification of the historical consumptive use credits. 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 call period. The attached Table 4 shows the net accretions /depletions for the 2013 and 2014 plan years. Conditions of Approval This SWSP is hereby approved pursuant to § 37 -90- 137(11), C.R.S., subject to the following conditions: 1. This plan is approved with the effective date of May 1, 2013 and shall be valid through April 30, 2015 unless otherwise revoked or modified. If this plan will not be made absolute by a water court action by the plan's expiration date, a renewal request must be submitted to this office with the statutory fee of $257 no later than March 15, 2015. 2. Well permit, Permit No. 75938 -F, has been obtained for the current uses and exposed pond surface area of the gravel pit in accordance with §37 -90- 137(2) and (11), C.R.S. 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 ground water exposed at the DeBeque Pit must not exceed 9.7 acres, which results in a maximum evaporative loss of 27.6 acre -feet per year (after the 3.4 acre - feet of phreatophyte credit). 5. The annual water used for dust control at the DeBeque Pit shall not exceed 1.5 acre -feet and the total product mined at the DeBeque Pit site shall not exceed 200,000 tons per year, which results in 5.88 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.
