("Cotter") received a report from Energy <br />Laboratories which included results for a July 13, 2010 stream sampling event conducted at <br />monitoring station SW-AWD. Monthly monitoring and reporting requirements for this <br />"upstream" station are specified in Paragraph 26 of the above referenced Notice of <br />Violation/Cease and Desist Order ("Paragraph 26"). Please find enclosed key excerpts of the <br />analytical data report that are specifically relevant to requirements of Paragraph 26, including <br />results for water samples collected on July 13, 2010 at sampling station SW-AWD. <br />Please note that certain analytical parameters specified Paragraph 26 could not be analyzed and <br />reported for this sample, i.e., Gross Alpha, Gross Beta, Ra-226+228, and weak acid dissociable <br />Cyanide. It is expected that all parameters specified in Paragraph 26 for "upstream" and <br />"downstream" locations (SW-AWD and SW-BPL, respectively), along with all other monitoring <br />requirements and schedules specified by WQCD, DRMS, and the Radiation Management Unit of <br />the CDPHE, will be included in sampling results going forward. <br />Also, please note that the "downstream" location (SW-BPL) was sampled on July 14, 2010 and <br />was submitted to the laboratory under separate chain of custody and sample submittal forms. <br />Those results have not yet been received by Cotter, but will be provided to WQCD under a <br />separate cover letter. Such results will be subject to the same limitations as noted above. <br /> <br />RECEIVE <br />'UG232010 <br />Cotter Corporation Telephone (719) 275-7413 <br />Canon City Mill, P.O.
