AVCOL ORADO <br /> Division of Reclamation, <br /> Mining and Safety <br /> Department of Natural Resources <br /> 1313 Sherman Street, Room 215 <br /> Denver, CO 80203 <br /> June 24, 2019 <br /> Kurt Blunt <br /> Blue Mountain Energy, Inc. <br /> 3607 County Rd. 65 <br /> Rangely, CO 81648 <br /> RE: Deserado Mine, Permit No. C-1981-018 <br /> 2018 Annual Hydrology Report <br /> Dear Mr. Blunt, <br /> The Division received the 2018 Annual Hydrology Report (AHR) on January 17, 2019 <br /> via email. Thank you for your timely submittal. The Division finds the 2018 AHR is in <br /> compliance with the following Rules: <br /> Rule 4.05.13(4)(a)—The data collected for the 2018 AHR is kept and maintained at the <br /> Deserado Mine Office. <br /> Rule 4.05.13(4)(b)—The 2018 AHR is compiled from the analysis of hydrologic data <br /> collected from the monitoring period of October 1, 2017 to September 30, 2018. <br /> Rule 4.05.13(c)(i), (ii), (iii) ' The 2018 AHR was submitted to the Division by the <br /> determined date on which the permittee and the Division agreed to. The report included <br /> an interpretation of the collected data and identified mining related impacts to the <br /> hydrologic balance. <br /> The 2018 data supports the predictions of the Probable Hydrologic Consequences (PHC) <br /> of the Deserado Mine permit. The following is a review of the 2018 data as per the PHC: <br /> The impact on the quantity of water to the White River was minimal, only <br /> 98,013,894 gallons or 301 acre-feet was withdrawn from the White River in the <br /> 2017 water year. This is less than the projected 552 acre-feet per year. <br /> Groundwater inflow is usually 20 to 40 galIons per minute(gpm), occasional <br /> increased inflows occur when a localized perched water table is encountered. <br /> Other inflows to the mine are the result of water from leaks and water line brakes. <br /> o�-cow <br /> e ' <br /> Q <br /> 1313 Sherman Street,Room 215, Denver,CO 80203 P 303.866.3567 F 303.832.8106 http://mining.state.co.us <br /> Jared S.
