�, l BIRISS May 28, 2020 � e 4 of In accordance with approach nos. 1 and 3, a bond for $115,000 has been obtained through DRMS. It is our understanding that this may be used for backfilling of the sediment pond and water basin, but is not adequate for backfilling of the Phase 2 mining pit. Therefore, in accordance with approach no. 4, you have indicated that the mineral lease between the Applicant and the landowner provides for the Applicant's use of the Lester-Attebery water rights in connection with the mining operation. You have indicated that the Applicant intends to fully utilize the Lester-Attebery Ditch rights as the sole replacement supply for a long-term augmentation plan for the Grisenti Pit. For the purposes of this SWSP, the lease agreement will be accepted for the dedication of the subject water rights; however, if the State Engineer determines that a different dedication process is necessary to assure proper dedication of water rights, additional information may be required prior to future SWSP approvals. 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 This plan shall be valid for the period of April 20, 2020 through March 31, 2022, unless otherwise revoked or superseded by decree. 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 February 1, 2022. 2. Approval of this SWSP supersedes the prior SWSP that was issued for the period of February 1, 2019 through January 31, 2021. The prior SWSP has no further force or effect. 3. The total surface area of the groundwater exposed after December 31, 1980 shall not exceed 51.1 acres for the period of this SWSP. 4. The annual volume of groundwater used for dust control shall not exceed 3.5 acre-feet. 5. The lagged depletions associated with this mining operation must not exceed 367.73 acre-feet during the period April 20, 2020 - March 31, 2021 and 214.34 acre-feet during the period April 1, 2021 - March 31, 2022. Documentation of pond size may be required by the Division Engineer in the form of an aerial photo evaluation or survey by a Professional Land Surveyor during the term of this plan. 6. Total consumption at the Grisenti Farms Pit must not exceed the aforementioned amounts, unless a new SWSP allowing such is approved by this office. 7. Approval of this plan is for the purposes as stated herein. Any additional uses of this water must first be approved by this office in a new SWSP. Any future additional historical consumptive use credit given (e.g., agricultural water transfer) for this site must consider all previous credits given. 8. Releases of water by Pueblo Board of Water Works pursuant to this plan shall be coordinated with the Water Commissioner and the Augmentation Coordinator and shall equal or exceed the depletions to be replaced on a monthly basis.
