These spills occurred during the month of March, <br />1999. This NOV is also being issued in conjunction with a CDMG inspection of the Foidel Creek Mine <br />conducted on April I. 1999, and laboratory analyses provided by TCC to the Division subsequent to [he <br />spills that indicate that the quality of this mine water exceeded certain federal effluent limits in both <br />instances. <br />The Division has requested as part of the abatement of this NOV the submittal of a Technical Revision to <br />revise the CDMG Foidel Creek Mine Permit. As discussed in a meeting between representatives of TCC <br />and the Division on April 6, 1999, the Division believes this is necessary so that the permit sections that <br />address the probable hydrologic consequences of mining and the impacts to the hydrologic balance are <br />revised to reflect the current and future hydrologic regime within and adjacent to the permit area. The <br />Division believes this is also necessary so that the designs for any underground mine water discharge <br />treatment systems reFlect both of these hydrologic scenarios. <br />Additionally, the Division is in the process of reviewing Twentymile Coal Company's application for <br />renewal (RN-03) of the Foidel Creek Mine permit. The Division hopes to approve the application for the <br />renewal prior to approving the application for the above-mentioned Technical Revision. <br />We appreciate the cooperation of Twentymile Coal Company in this matter. Please do not hesitate to <br />contact me at (303) 866-3567 if you have any questions. <br />Si//n~~cerelyr- ,, <br />.~A.CG<.cL~ ~ ~~n.:(,slL~clF <br />Daniel 1 Hernandez /J <br />Senior Environmental Protection Specialist <br />Enclosure (NOV CV-99-003) <br />CC: David Berry, Coal Program Supervisor <br />Janet Binns.
