NCCI Pit#1 Substitute Water Supply Plan Page 3 of 4 January 29, 2024 Data Submittal DWR's website under Services / Data and Information in the Online Data Submittal Section. 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. Additional information regarding accounting requirements can be found in the attached Augmentation Plan Accounting Administration Protocol for Division One. NOTE: Monthly accounting, even during the winter non-irrigation season, is required. In addition, the Applicant shall verify that the entity making replacement for this SWSP is including that use on their monthly accounting submitted to this office. For the purposes of this SWSP, that entity is the City of Thornton (WDID 0202611). 6. Applicant may refer to the Augmentation Plan Accounting Administration Protocol for the operation of this SWSP. 7. Conveyance loss for delivery of augmentation water is subject to assessment and modification as determined by the Division Engineer. Currently 0.5% per mile conveyance loss is being accounted for in the SWSP; this is subject to change depending upon current conditions. 8. Replacement water must be made available to replace all out-of-priority depletions in time, place, and amount and must be made available under the direction and/or approval of the water commissioner. 9. All releases of replacement water must be sufficient to cover all out of priority depletions and be made under the direction and/or approval of the Water Commissioner. The replacement may be aggregated to maximize beneficial use. The Water Commissioner and/or Division Engineer shall determine the rate and timing of an aggregated release. 10. In order to prevent injury to other water rights, the division engineer and water commissioner must be able to administer Applicants' replacement water past headgates on the river at times when those headgates would otherwise be legally entitled to divert all available flow in or "sweep" the South Platte River or its tributaries. Applicant shall not receive credit for replacement of depletions to the South Platte River below such diversion structures unless bypass and measurement structures are in place to allow the division engineer and water commissioner to confirm that Applicant's replacement water is delivered past the headgates. In the event that delivery past dry-up points requires the use of a structure for which a carriage or use agreement with a third party is required, Applicant shall be responsible for securing such agreement. Until such time as the Applicant provides a copy of the carriage or use agreement to the division engineer and water commissioner, no credit will be allowed for replacement of depletions to the South Platte River below such diversion structure. 11. The Division of Water Resources will not be responsible for any enforcement or administration of third party agreements that are not included in a decree of the water court. 12. The name, mailing address, and phone number of the contact person who will be responsible for operation and accounting of this plan must be provided on the accounting forms to the Division Engineer and Water Commissioner. 13. The approval of this SWSP does not relieve the Applicant and/or landowner of the requirement to obtain a Water Court decree approving a permanent plan for augmentation or mitigation to ensure the permanent replacement of all depletions, including long-term evaporation losses and lagged depletions after gravel mining operations have ceased. If reclamation of the mine site will produce a permanent water surface exposing groundwater to evaporation, an application for a plan for augmentation must be filed with the Division 1 Water Court at least three (3) years prior to the completion of mining to include, but not be limited to, long-term evaporation losses and lagged depletions. If a lined pond results after reclamation, replacement of lagged depletions shall continue until there is no longer an effect on stream flow.
