PAM The Pittsburg ~ Midway Coal Mining Co. <br />A Chevron Company <br />64CU Sou(h Fdd!er's Green Circle, Eng!ewwd, CO 80111-0991 <br />Mail Address: P.O. P,oK 6518, Englewood. CO 801SS-6518 ~ FAX (303) 9304204 ~ Pho <br />Colorado Department of Health <br />WQCD-PE-B2 <br />4300 Cherry Creek Drive South <br />Denver, Colorado 80222-1530 <br />RECEIVED <br />ne 1303) 9303600 <br />FEB 0 g 2000 <br />Dear Sir/Madam: <br />Division of Minerals 8 Geology <br />February 7, 2000 <br />CDPS Permit CO-0032638 <br />Enclosed, please find the December 1999 CDPS results and fourth quarter 1999 WET testing <br />results for the Edna Mine (Permit CO-0032638). DMP 001 did not discharge during the <br />monitoring period. DMP 004 and 007 had discharge during the monitoring period. <br />Submittal of the results have been delayed due to technical difficulties with the laboratory <br />providing the analyses. P&M regrets any inconvenience the delay in reporting may have caused. <br />P&M is currently reviewing the laboratory's protocols to ensure a more timely submittal of <br />results in the future. <br />Both DMP 004 and 007 exceeded the permit's sulfate criteria. Due to the delay in analyses <br />reporting from the laboratory, a second set of samples was not able to be tested during the <br />monitoring period to determine if sulfate levels had receded. The sample with the high sulfate <br />level taken at DMP 004 was collected during the first week of the monitoring period. DMP 004 <br />discontinued dischazging shortly thereafter with no discharge occurring during the remainder of <br />the monitoring period. The first sample taken and analyzed for sulfate at DMP 007 subsequent <br />to the exceeded value showed that sulfate concentrations were in compliance with permit criteria. <br />Should you have any questions regarding these reports, please contact meat the Edna Mine. <br />Sincerely, <br />cc: Mine File <br />CDMG <br />~~~n ...~..5~____ <br />Brian D. Gontazek <br />Sr. Environmental Engineer <br />
