Inouye Pit SWSP Page 4 of 7 March 24, 2022 released from the Metro Waste Water Treatment Plant ("Metro") to the point of depletion. The leased water includes additional water to cover transit losses. Transit losses were estimated based on a 0.5 percent loss per mile and a distance of 25.5 miles. While the Applicant proposes to provide replacement water from Metro when the call requires, CCWCD may provide replacements further downstream, which requires administrative exchange approved by the Division Engineer. If any replacement supplies are used downstream of the City of Fort Lupton, prior approval from, and advanced notice to, the Water Commissioner is required. The use of downstream replacement supplies cannot be used when advanced notice and permission has not been given, when there is an intervening call between the City of Fort Lupton and the location where the substitute supply is introduced, and when there is not sufficient flow (e.g., an intervening dry up location on the river). If prior approval by the Water Commissioner has not been obtained, CCWCD must make releases from Metro. Long Term Augmentation In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of Reclamation, Mining, and Safety ("DRMS"), all sand and gravel mining operators must comply with the requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the protection of water resources. The April 30, 2010 letter from DRMS requires that you provide information to DRMS to demonstrate you can replace long term injurious stream depletions that result from mining related exposure of groundwater. The DRMS letter identifies four approaches to satisfy this requirement. In accordance with approach nos. 1 and 3, you have indicated that a bond has been obtained for $3,082,695.00 through the DRMS for lining of this site to assure that depletions from groundwater evaporation do not occur in the unforeseen event, or events that would lead to the abandonment of the Pit. 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 is approved with the effective date of April 1, 2022 and shall be valid through March 31, 2023 unless otherwise revoked or superseded by a decree. If this plan is not decreed in water court by the SWSP expiration date, a renewal request must be submitted to this office with the statutory fee of $257 no later than February 1, 2023. 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 84266-F has been issued for this pit. The permit covers up to 4.0 acres of exposed surface area, dust suppression, and dewatering activities. The average annual amount of groundwater that can be appropriated shall not exceed 25.02 acre-feet, including dewatering, evaporative loss, dust control, and water lost in mined product. A new well permit must be obtained for the gravel pit in accordance with sections 37-90-137(2) and (11), C.R.S. Awe[[ permit application has been submitted to this office (receipt no. 10018697) and this application is pending evaluation. Until this gravel pit well permit is approved, consumptive use and exposure of groundwater on this site is limited to the uses and amounts allowed by permit no. 84266-F. 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 held in accordance with the procedural rules in 2 CCR 402-5. 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 SWSP may be canceled.
