Page 2 <br /> Hatchery Pit - M-2014-043 <br /> January 7, 2019 <br /> However, the Division would like quarterly monitoring to continue until the seasonal <br /> water level regime can be adequately documented to have stabilized. Please revise the <br /> monitoring plan to indicate two years after the clay liner has been installed the Operator <br /> will evaluate if the groundwater regime has sufficiently stabilized and will obtain DRMS <br /> approval prior to reducing the water monitoring frequency to annually. <br /> I have revised the text in the 6roundwater Monitoring Data Analysis and Data Collection <br /> and Submittal sections to incorporate the wording on seeking Division approval prior to <br /> going to once a year monitoring. <br /> Reclamation Cost Estimate <br /> 3.) The Division has reviewed the reclamation cost estimate provided by the applicant. The <br /> Division cannot release liability associated with the Phase 1 slurry wall until it has been <br /> certified and approved by the Colorado Division of Water Resources. Once certified and <br /> approved, the Division can release 80% of the liability associated with the slurry wall and <br /> will hold 20% for possible repairs until mining and reclamation is complete at the site. <br /> Enclosed is a reclamation cost estimate conducted by the Division based on the <br /> information submitted with the adequacy review response. Please advise the Division if <br /> you concur with the estirnaie. <br /> We concur with your numbers but request that the amount be rounded to the closest <br /> hundred dollars ($1,056,100.00). <br /> If you have more questions or need more information please call me at (303) <br /> 423-7297. <br /> Sincerely, <br /> -5�60'e-- <br /> Stevan L.
