TR-27 consists of a revised Water Quality Monitoring Plan(WQMP),Version R4,to replace the <br /> current version in the Climax Environmental Protection Plan(submitted as TR-24). This WQMP revision <br /> is submitted pursuant to consultation with DRMS and in response to DRMS letters of October 20,2017 <br /> and November 15,2017. DRMS had requested that Climax submit an updated WQMP that adopts CBSG <br /> table values as NPLs as provided for in the Interim Narrative Standard for all POC wells currently <br /> identified in the WQMP,with the exception of manganese that is above the CBSG table values in the <br /> Arkansas River and Eagle River basins. In accordance with the plan submitted to DRMS on January 18, <br /> 2018, Climax will seek development of site-specific groundwater classifications and standards for <br /> manganese for the Arkansas River and Eagle River basins. <br /> This revision to the WQMP contains much of the same information as Version R3 (TR-24)but with <br /> updated information,where applicable,to reflect current conditions. More specifically,the revision to the <br /> WQMP, incorporates the results of baseline monitoring that has been conducted since the water quality <br /> monitoring program began in 2011, and presents an evaluation of this data to develop final indicator <br /> parameters to be used for long-term monitoring, subject to the approval of DRMS. <br /> Enclosed is a hard copy of the WQMP,Version R4,and the$1,006.00 fee applicable to a 112d operation. <br /> Please feel free to contact me at 719-486-7584 if you need any additional information. <br /> Sincerely, <br /> Raymond Laz <br /> Environmental Manager <br /> enc. <br />
