Well permit no. 66319-F was approved pursuant to §37-90-137(2), C.R.S., for the proposed operational uses. 4. Approval of this SWSP is for the purposes stated herein and pumping is limited to the wells identified above. Additional wells and/or additional uses for the water that is the subject of this SWSP will be allowed only if a new SWSP is approved for those additional wells/uses and such additional wells/uses. 5. The total surface area of the ground water exposed must not exceed 2.0 acres,which results in a maximum evaporative annual loss at the Heit Sand and Gravel Mine of 5.82 acre-feet. 6. The annual amounts of water used at the Heit Sand and Gravel Mine shall not exceed 1.0 acre- feet for dust control, and the total amount of aggregate washed shall not exceed 485,000 tons per year, resulting in a consumptive use of 10.7 acre-feet of water. The annual amount of water used at the site for operational purposes therefore shall not exceed 11.7 acre-feet. 7. Total consumption at the Heit Sand and Gravel Mine must not exceed the aforementioned amounts unless an amendment is made to this plan. 8. Approval of this plan is for the purposes as stated herein. This office must first approve any additional uses for the water. 9. All releases of replacement water must be sufficient to cover all out-of-priority depletions in time, place, and amount and must be made under the direction and/or the approval of the water commissioner. The release of replacement water may be aggregated to maximize beneficial use. The water commissioner and/or the division engineer shall determine the rate and timing of an aggregated release. 10. 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. 11. All diversions shall be measured in a manner acceptable to the Division Engineer. The Applicant shall install and maintain such measuring devices as required by the Division Engineer for operation of this SWSP.
