At the meeting, the results of the <br />Division's review of the permit file to determine the potential <br />long term migration of radionuclides and trace metals in <br />concentrations significant to impact public health and safety were <br />discussed. The Division does not think that a significant: risk of <br />impact to the public health and safety exists at the site at this <br />time and, therefore, determines that the Schwartzwalder Mirle should <br />not be a considered a Designated Mining Operation. In reaching <br />this conclusion, the Division reviewed the following documents <br />included in the permit file: <br />1. The original 1977-1983 permit application and amended <br />permit application documents. <br />2. The 1977 report entitled "Spill Prevention and Contain- <br />ment Plan for Control of Pollutant Discharge Streams at <br />Schwartzwalder Mine" by Hazen Research, Inc. <br />3. The 1980 Amended Application for Radioactive Materials <br />License by Cotter Corporation. <br />4. The 1983 report entitled "Ore Sorter Flood Protection/ <br />Scour Analysis" by McDermid Engineering Associates, Inc. <br />5. The 1983 document "Responses to State of Coloradc Mined <br />Land Reclamation Division Comments on Waste Pile Related <br />Portions of Permit Amendment Application" by McD~=_rmid <br />Engineering Associates, Inc. <br />
