ASCI Turnpike Mining Resources SWSP Page 3 of 6 December 13, 2023 Town of Erie's North Water Reclamation Facility is located in Section 31, Township 2 North, Range 68 West, 6th P.M., therefore no transit losses are assessed for this replacement source. Conditions of Approval I hereby approve the proposed SWSP in accordance with section 37-90-137(11), C.R.S. subject to the following conditions: 1. This SWSP shall be valid for the period of January 1, 2024 through December 31, 2024, unless otherwise revoked, or superseded by decree.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 (currently $257), with all necessary leases and other supporting documentation, no later than November 1, 2024. If a renewal request is received after the expiration date of this plan, it may be considered a request for a new SWSP and the $1,593 filing fee will apply. 2. Well Permit 82220-F has been issued for this pit, in accordance with section 37-90-137(2), C.R.S. The permit covers up to 8 acres of exposed surface area and allows for annual water uses of up to 25.81 acre-feet for evaporation losses, water lost with the mined product, and dust control. Actual depletions cannot exceed these amounts and are limited to those uses specifically approved through this SWSP. A new well permit must be obtained for the pit in accordance with section 37-90- 137(2), C.R.S., and this SWSP in order to allow the requested exposed surface area and evaporative depletions. Any application will be evaluated subsequent to approval of this SWSP. The provisions of section 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 in accordance with the procedural rules in 2CCR402-5. The hearing will 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. This SWSP may only be operated for the proposed exposed surface area and evaporative depletions if a permit allowing such uses is obtained. 3. The total surface area of the groundwater exposed at the Turnpike Mining Resource site must not exceed an area of 15.23 acres which results in an annual depletion of 38.10 acre-feet. Total consumption at the Turnpike Mining Resource site must not exceed these aforementioned amounts unless an amendment is made to this SWSP. 4. Approval of this SWSP is for the purposes as stated herein. This office must first approve any additional uses for the water. Any future additional historical consumptive use credit given (e.g., agricultural water transfer) for this site must consider all previous credits given. 5. 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. All replacement water must be concurrent with depletions in quantity, timing, and locations. 6. The Applicant shall provide daily accounting (including, but not limited to diversions, depletions, replacement sources, and river calls) on a monthly basis. The accounting must be uploaded to the CDSS Online Reporting Tool within 30 days of the end of the month for which the accounting applies (https://dwr.state.co.us/Tools/reporting). Instructions for using the tool are available on the Division of Water Resources website on the "Services" —> "Data Et Information" page under the heading of Online Data Submittal. Accounting and reporting procedures are subject to approval and modification by the division engineer. Accounting forms need to identify the WDID number for each structure operating under this SWSP.
