Mr. Peter Foster December 6, 2012 Colona Gravel Pit, Substitute Water Supply Plan Page 4 of 7 water used for dust control. Since the existing permit does not cover the 6.8 acres of exposed ground water identified in this plan and the increased water lost by filling the gravel pit, a new well permit must be obtained for the current use and exposed surface area of the gravel pit in accordance with §37 -90- 137(2) and (11), C.R.S. in conjunction with this plan. Applicant is required to submit a well permit application within 30 days of receipt of this plan. The provisions of Colorado Revised Statute 37 -90- 137(2) prohibits 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 substitute supply plan may be cancelled. 4. For Year 1 of the renewal period, the total area of exposed groundwater shall not exceed 6.8 acres and the total consumptive use of the mining operation shall not exceed 41.0 acre -feet, of which 17.37 acre -feet is due to evaporative losses, 20.7 acre - feet to ground water filling of the pit resulting from mining of 60,000 tons of aggregate, and 3.0 acre -feet to water use for dust suppression. For Year 2 of the renewal period, the total area of exposed groundwater again shall not exceed 6.8 acres and the total consumptive use of the mining operation shall not exceed 30.7 acre -feet, of which 17.37 acre -feet is due to evaporative losses, 10.3 acre -feet to ground water filling of the pit resulting from mining of 30,000 tons of aggregate, and 3.0 acre -feet to water use for dust suppression. Any increases in depletions must be submitted to this office as an amendment to this plan. 5. Approval of this plan is for the purposes as stated herein. Any additional uses of this water must first be approved by this office. If it is anticipated that the total surface area exposed will exceed those amounts, an amendment will need to be filed with this office prior to such expansion. 6. All pumping for dust control shall be measured in a manner acceptable to the division engineer. 7. Replacement water is to be supplied from the Ouray Ditch and Ridgway Reservoir during the irrigation season and from Blue Mesa Reservoir for the non - irrigation season, and will be released /delivered according to the schedule included in Table 3 of this plan, subject to modification by the division engineer or water commissioner. Transit losses may be modified, as determined necessary, by the division engineer per CRS 37 -80- 102(7) & CRS 37 -83 -104. 8. 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 plan cannot be sold or leased to any other entity. As a condition of subsequent renewals of this substitute water supply plan, 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 water attributable to the Applicant's 2.5 shares in the Ouray Ditch may not be used elsewhere or for any other purpose during the term of this plan. 10. All deliveries of replacement water shall be measured in a manner acceptable to the
