Mr. Todd Williams, P.E. April 21, 2014 Page 4 of 6 9. The Applicant must notify the water commissioner prior to the release of the City of Fort Collins reusable water from Fossil Creek to ensure the water is properly accounted for in the Fossil Creek reservoir accounting. 10. The replacement water that is the subject of this plan cannot be sold or leased to any other entity. As a condition of subsequent renewals of this substitute water supply plan, 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. 11. All diversions shall be measured in a manner acceptable to the Division Engineer. The Applicant shall install and maintain such measuring devices as required by the Division Engineer for operation of this SWSP. For the purposes of this SWSP, the Division Engineer requires a totalizing flow meter (TFM) to be installed on all dewatering operations. 12. Adequate accounting of depletions and replacements must be provided to the division engineer in Greeley (Div1Accountin @state.co.us) and the water commissioner (Mark. Simpson@state.co.us) on a monthly basis, or more frequent if required by the water commissioner. All amounts shall be in acre -feet. 13. 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. 14. Applicant shall follow the Augmentation Plan Accounting Protocol, or any other applicable protocols as referenced in the attached documents, for the operation of this SWSP. 15. Conveyance loss for delivery of replacement water is subject to assessment and modification as determined by the division engineer. 16. The proposed replacement source for the depletions accruing to the Cache la Poudre River resulting from this gravel pit are excess credits associated with a recharge project utilizing 2.5 shares of the Box Elder Ditch as previously approved for augmentation use in conjunction with the Applicant's Timnath- Connell Pit (M- 1999 -050). It is the Applicant's responsibility to ensure that the Timnath- Connell Pit accounting reflect the monthly excess credits used by this SWSP. As the Applicant owns both the SerFer and Timnath- Connell Pits, combined accounting is acceptable. 17. 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. 18. Dewatering at this site will produce delayed depletions to the stream system. As long as the pit is continuously dewatered, the water returned to the stream system should be adequate to offset the depletions attributable to the dewatering operation. Once dewatering at the site ceases or is reduced in volume, the delayed depletions must be addressed. Accordingly, dewatering is required to continue during the term of this approval. At least three years prior to completion of dewatering at the SerFer Pit, a plan must be submitted that specifies how the post pumping dewatering depletions will be replaced in time, place and amount.
