Lang <br />Divaion DBector <br />The Division of Minerals and Geology has reviewed the Discharge Monitoring Reports (reports) <br />for the New Elk mine, CDPS permits COG-310069 and CO-0000906 for the 15` and 2nd quarters <br />1999. <br />15' quarter 1999 <br />The DMR(report) for COG-310069 indicates no discharge during the 15t quarter from the now <br />inactive Remediation System. This is consistent with field inspection observations during the <br />quarter. Noted in the Division records is a letter dated May 4, 1999 from the Oil Inspection <br />Section of the Department of Labor that relieves Picketwire Processing, LLC of further <br />investigation and remediation at this site. Field inspection also confirmed no discharge at any of <br />the sediment pond outfa115 covered under permit CO-0000906 during the 15t quarter. <br />2nd quarter 1999 <br />The report for COG-310069 again indicates no discharge during the 2"d quarter from the now <br />inactive Remediation System. This is consistent with field inspection observations during the <br />quarter. Discharge was noted and sampled at the pond 007 outfall twice during the 2nd quarter. <br />The cover letter submitted with the reports indicated two storm events, one in early May and the <br />other on June 12. As we discussed by phone on August 20, 1999, it appears that the reported <br />flow value indicates only one discharge value. It is also not clear whether the 30 day average <br />for total suspended solids(TSS) should be an average of the two TSS values or the largest <br />average value over the three thirty day periods in the quarter. Please clarify and(or modify this <br />information as necessary. <br />If you have questions, please call me. <br />Si1nc~e'~""ly'~~~7 f ~ <br />Ke t/~ A.
