This SWSP shall be valid for the period of January 1, 2021 through December 31, 2021, unless otherwise revoked or superseded by decree. Should a request for renewal of this plan be needed, such renewal request must be submitted to this office with the statutory fee (currently $257 per pit) no later than November 1, 2021. If a renewal request is received after the expiration date of this plan, it may be considered a request for a new SWSP in which case the filing fee for a new SWSP will apply (currently $1,157 per pit). 2. Well permits have been obtained for the current use and exposed groundwater surface area of each gravel pit in accordance with sections 37-90-137(2) and (11), C.R.S., as identified in Table A of this approval, with the exception of the Fredstrom Pit . A gravel pit well permit application for the Fredstrom Pit was submitted to this office and is currently pending under receipt no. 3691674, subject to the resolution of a hearing scheduled to be held before the Hearing Officer in case no. 19SE01. 3. The total area of groundwater surface exposed after December 31, 1980 for each of the pits shall not exceed those values listed in Table A of this approval. Should the total surface area exposed exceed those amounts, an amendment will need to be filed with this office. 4. The total amount of groundwater to be consumed at each of the pits shall not exceed the values listed in Table C of this approval. Total consumption at each pit must not exceed these amounts unless an amendment is made to this plan. 5. Approval of this plan is for the purposes as stated herein. This office must first approve any additional uses for the water. Any future additional historic consumptive use credit given (e.g., agricultural water transfer) for these sites must consider all previous credits given. 6. 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(s). If approved prior, the release of replacement water may be aggregated to maximize beneficial use. The water commissioner(s) and/or the division engineer shall determine the rate and timing of an aggregated release. 7. Conveyance loss for delivery of replacement water is subject to assessment and modification as determined by the division engineer. The distance for assessment of conveyance loss will be based upon DWR stream miles or as approved by the Water Commissioner, and will be assessed from the point of release to the point of depletion/replacement. 8. The replacement water, which is the subject of this plan cannot be sold or leased to any other entity unless prior approval is obtained from the state or division engineer. As a condition of subsequent renewals of this substitute water supply plan, the replacement water must be appurtenant to these sites until a plan or plans for augmentation are obtained. All replacement water must be concurrent with depletions in quantity, timing, and locations.
