Box 1299 <br />Paonia, Colorado 81428 <br />RE: Orchard Valley Mine, C-81-038, Second Quarter 1990 Reports <br />Dear Mr. Menke: <br />The Division has reviewed this quarterly report. We have the following <br />concerns: <br />1. Item 11 of the Quarterly Waste Disposal Area Inspection Report <br />states that a portion of the waste pile doesn't meet compactive <br />standards as stated in TR 07. What provisions are being taken to <br />rectify this situation? <br />2. The East Roatcap Creek monitoring Report shows nearly a year and <br />one half period of 0.004 CFS flow rates through spring thaws, <br />winter and Sumner periods. Since March, 1990 no flow rates were <br />taken. With the wide fluctuations in TSS and TDS levels during <br />this period it seems difficult to assume that a static flow pattern <br />existed. Please clarify this situation. <br />The pond inspections and NPDES Reports appear to be in order and proper. <br />We thank you for this report and await your responses to the two above <br />questions. <br />Sincerely, <br />.~~1~ ~ <br />J.
