During the month of September 2000, DMP 001 did not <br />discharge. DMP 004 did not exceed the compliance criteria during the monitoring period. <br />A grab sample taken a[ DMP 007 on August 1, 2000, exceeded the WET test compliance criteria <br />for P. Promelas. Pittsburg and Midway Coal Mining Company (P&M) notified CDPHE via a letter dated <br />August 9, 2000 that accelerated testing would be performed a[ DMP 007. Accelerated tests were <br />performed on samples collected on August I5, 2000 and August 24, 2000. P&M notified CDPHE via a <br />letter dated September 7, 2000 that both accelerated samples passed compliance criteria, resulting in a <br />pattern of no toxicity. <br />Please contact me at (307) 742-0031 with any questions or comments you have regarding this <br />matter. <br />SL:sb <br />Enclosures <br />File: 99-144 <br />Sincerely, <br />Steve Linse, P.E. <br />Project Engineer <br />OTHER LOCAT/ONS <br />1839 Terra Avenue 107 Easl First $treel 701 Antler Drive, Suite 233 <br />Sheridan, Wyoming B?801 Gillette, Wyoming 82716 Casper, Wyoming S?601 <br />Phone (307)672 0761 Phone (307)68?-IR80 Phone 13077473-2707 <br />Fax (3(17) 673-4'65 Fux (3077 682-'_257 Fax U07) 237-OR2g <br />E-mail: infwhrrmwwcengineering.com E-mail: infoglt@wwcen¢ineerin¢.com E-mail: infocsp@wwcengineenng.com <br />32 South Ewing.
