The DMR for outfall 004 was inadvertently (eft <br />out of the mailing, which transmitted the DMR for outfall 007 and a report on the wet test <br />variance results, submitted that same month. Please add this DMR to September 2004 file. <br />During the month of September 2004, DMP 004 was operating under a variance, arrange <br />with Mr. Jeff Coombe (CDH), to evaluate an apparent wet test failure. Samples were sent to two <br />laboratories for accelerated testing. The second laboratory did not have any failures. P&M Coal <br />has changed laboratories for wet tests. The mailing you received in October 2004 explained <br />these results in more detail, and included the remaining DMR pages. <br />I'apologize for the oversight. Please feel free to call me at (307) 742-0031 ext. 19 or <br />email me at bheesen@wwc engineering.com with any questions or comments you have regarding <br />this matter. <br />Sincerely, <br />1~~7 -v'`-!~- <br />Beth A.
