Mr. Todd Williams <br />Timnath - Connell SWSP <br />March 27, 2013 <br />18. The Timnath - Connell Pit has been continuously dewatered. Dewatering operations at this <br />site create lagged accretions that mimic its lagged depletions due to the recharge of <br />dewatering water. The Applicant intends to line the pit when mining activity is complete, <br />and none of the currently dewatered areas will be within the unlined lakes after <br />reclamation. Therefore the site should not experience water Toss associated with a `first fill' <br />that occurs when unlined gravel pits are allowed to fill with ground water. The Applicant <br />proposes that in accordance with the current dewatering plan, once dewatering at the site <br />ceases, there will not be any post - pumping depletions that must be addressed. <br />19. If dewatering of the Timnath - Connell Pit were discontinued prior to the completion of a <br />liner, the pit would fill creating additional depletions to the stream system and resulting in <br />increased evaporation. Additionally, should an augmentation plan not be obtained for the <br />unlined lakes, long term depletions to the stream system would result. To assure that <br />additional or long term depletions to the river do not occur, a bond for $510,198 for the <br />Timnath - Connell Pit for lining or backfilling of the pit was obtained in 1999 through DRMS. <br />This bond was determined to be sufficient by DRMS during a site inspection on August 31, <br />2012. <br />20. In accordance with amendments to §25 -8- 202(7), C.R.S., and "Senate Bill 89 -181 Rules <br />and Regulations" adopted on February 4, 1992, the State Engineer shall determine <br />whether the substitute supply is of a quality to meet requirements of use to senior <br />appropriators. As such, water quality data or analysis may be requested at any time to <br />determine if the water quality is appropriate for downstream water users. <br />21. The decision of the state engineer shall have no precedential or evidentiary force, shall not <br />create any presumptions, shift the burden of proof, or serve as a defense in any pending <br />water court case or any other legal action that may be initiated concerning this plan. This <br />decision shall not bind the state engineer to act in a similar manner in any other <br />applications involving other plans, or in any proposed renewal of this plan, and shall not <br />imply concurrence with any findings of fact or conclusions of law contained herein, or with <br />the engineering methodologies used by the Applicant. <br />Should you have any questions or comments, please contact Jonathan Hernandez in <br />Greeley at (970)- 352 -8712 or Joanna Williams in Denver at (303)- 866 -3581. <br />Sincerely, <br />atherage, P.E. <br />of Water Supply <br />Attachments: Table 4 and 8 <br />Box Elder Dry Up Map dated 2/10/2013 <br />Administration Protocol "Augmentation Plan Accounting, Division One — South Platte River" <br />Administration Protocol "Dry-Up of Irrigated Land, Division One — South Platte River" <br />Cc: Jonathan Hernandez, Water Resource Engineer, jonathan.hernandez.state.co us <br />810 9 Street, Suite 200, Greeley, CO 80631, (970) 352 -8712 <br />Mark Simpson, Water Commissioner, Water District 3, mark.simpson@state.co.us <br />951 Wheatridge Cir, Loveland, CO 80537; (970) 420 -9568 <br />Division of Reclamation, Mining and Safety <br />JD /jmh/Timnath- Connell 2013- 14.docx <br />Page 6 <br />
