Beverlin <br />Resident Engineer <br />The Pittsburg and Midway Coal Mining Co. <br />P.O. Box 176 <br />Oak Creek, Colorado 80467 <br />RE: Edna Mine, C-80-001, Quarterly Pond Inspections and Flay, 1990 NPDES and <br />Water Sampling Monitoring Report <br />Dear Mr. Beverlin: <br />The Division reviewed the two reports and has the following comments: <br />1. The pond inspection comments are verified by observations during <br />our inspections. Your use of the sediment trap appears to be very <br />successful at West Ridge Pond (NPDES 002). We will be interested <br />in the actual increase of time between clean outs of the pond <br />because of this measure. <br />2. This report was reviewed and found to be adequate. <br />Sincerely, <br />/~~- <br />J. M. Clayton <br />Reclamation Specialist <br />J MC/y,i b <br />8208E <br />
