Ms. Sandy Squire <br />June 20, 1985 <br />Page 2 <br />Oscar Beck of Mestern Slope, after consulatlon with Gary Fritz of the Office <br />of Surface Mining, Susan Mowry and Dan Mathews of Colorado Mine Land <br />Reclamation, conducted an investigation that found rto possible source of oil <br />and grease from company facilities or activities. Possible reasons for the <br />high oil and grease level are: <br />1. Runoff <br />The Colorado Highway Department is currently working on a highway <br />expansion project through this area. It 1s possible that oil and <br />grease from their equipment entered one of our diversion ditches <br />and then entered the pond via precipitation. We have experienced <br />increased siltation 1n our ditches and have had to increase ditch <br />maintenance since the Highway Department began working in the area. <br />2. Improper Sampling or Analytical Methods <br />It is also possible, though perhaps less likely, that the sample <br />results are 1n error. We have checked with the environmental <br />Inspector at that mine who is sure that there was no visible sheen <br />on the surface of the pond when the water was discharged. It 1s <br />unlikely that a 40 mg/1 oil and grease level would not produce a <br />significant sheen. However, the laboratory believes their ana~'Sis <br />is correct. <br />All necessary steps will be taken to assure compliance with permit limits. <br />Visual inspections will be made as specified with samples taken when <br />conditions require. If a sheen is observed the pond will be skimmed prior to <br />discharge. <br />We hope that this letter has addressed your concerns and will be happy to <br />further discuss the matter 1f necessary. Please feel free to glue me a call <br />at (801) 584-6999 if you have further questions. <br />Sincerly, <br />~1~,~ <br />~C <br />H. L. Bauerle <br />Environmental Specialist <br />HLB/bno <br />Attachment <br />1454-63 <br />
