Chavers Mining Resources Substitute Water Supply Plan 2022 Page 6 of 8 <br /> June 27, 2022 <br /> by the division engineer. Accounting forms need to identify the WDID number for each structure <br /> operating under this SWSP. Additional information regarding accounting requirements can be found in <br /> the attached Augmentation Plan Accounting Administration Protocol for Division One. NOTE: Monthly <br /> accounting, even during the winter non-irrigation season, is required. <br /> In addition, the Applicant shall verify that the entity making replacements has included the Applicant <br /> on their accounting and submitted their accounting to the division office and the Water Commissioner; <br /> for this SWSP, that entity is the City of Aurora. <br /> 8. Conveyance loss for delivery of augmentation water to the point of depletion on the South Platte <br /> River is subject to assessment and modification as determined by the Division Engineer. <br /> 9. The Division Engineer, or their designated representative, will administer all such water transported in <br /> the South Platte River or its tributaries under this SWSP, including water for replacement of <br /> depletions, past intervening headgates to ensure that such water is not intercepted or otherwise <br /> diminished in quantity by diversion, use or other interference by intervening water rights and to <br /> assure that such water remains available and suitable for Applicant's uses under this SWSP, except <br /> when any intervening headgate is diverting the entire flow of ("sweeping") the river. In the event <br /> that delivery past headgates which sweep the river requires the installation of a bypass structure or <br /> the use of an existing bypass structure by agreement with a third-party, Applicant is responsible for <br /> either installing a new bypass structure with a continuous recording measuring device(s) as approved <br /> by the Water Commissioner or securing an agreement with a third-party to use an existing bypass <br /> structure and providing such information and agreement to the Division Engineer. <br /> 10. The State Engineer will not be responsible for any enforcement or administration of third party <br /> agreements that are not included in a decree of the water court. <br /> 11. The name, mailing address, and phone number of the contact person who will be responsible for <br /> operation and accounting of this plan must be provided on the accounting forms to the Division <br /> Engineer and Water Commissioner. <br /> 12. Dewatering at this site will produce delayed depletions to the stream system. As long as the pit is <br /> continuously dewatered at a relatively constant rate, the water returned to the stream system <br /> should be adequate to offset the depletions attributable to the dewatering operation. Dewatering <br /> operations must be measured by totalizing flow meters that can accurately show the monthly <br /> volume of dewatered water that is pumped and returns to the stream. If dewatering at the site <br /> ceases, or is significantly reduced, the monthly meter readings will be used to determine post <br /> pumping depletions that must be replaced. At least three years prior to completion of <br /> dewatering, a plan must be submitted that specifies how the post pumping dewatering depletions <br /> (including refilling of the pit) will be replaced, in time, place and amount. Should it be <br /> determined by the Water Commissioner or Division Engineer that dewatering water is being <br /> diverted for any purpose by the operator and accounting is not adequate to show that 100 <br /> percent of the dewatering water is returned back to the South Platte River, the Applicant will <br /> need to account for any lagged dewatering depletions at the site. In addition, if it is determined <br /> by the Water Commissioner or Division Engineer that the pit is not continuously dewatered at a <br /> relatively constant rate then the Applicant must track depletions and dewatering return flows in <br /> their accounting and replace any dewatering depletions that are not offset by dewatering return <br /> f lows. <br /> 13. In accordance with the letter dated April 30, 2010 (copy attached) from the Colorado Division of <br /> Reclamation, Mining, and Safety ("DRMS"), all sand and gravel mining operators must comply with the <br /> requirements of the Colorado Reclamation Act and the Mineral Rules and Regulations for the <br /> protection of water resources. The April 30, 2010 letter from DRMS requires that the Applicant <br /> provide information to DRMS to demonstrate they can replace long term injurious stream depletions <br />
