Dept. o! A~atural Resoerces <br />DENVER--The Colorado Department of Health issued a radioactive materials li- <br />tense to Cottez Corporation Tuesday for some activities at the company's Schwartz- <br />walder Mine operation northwest of Golden. <br />The license is for an ore crusher-sorter, ore transfer pad and mine water <br />sludge handling operation at Schwartzwalder, according to Al Hazle, director of the <br />Radiation Control Division of the Eiealth DepartmenC. <br />Hazle said the license requires many of the same occupational and environmental <br />monitoring steps as are required of uranium milling operations, although there is <br />no chemical processing of uranium ore at the site. The wet uranium ore comes out <br />of the mine into the ore crusher-sorter and is then trucked to an ore transfer pad. <br />It is then loaded in covered trucks to be taken to Cotter's Canon City uranium mill. <br />The license requires environmental monitoring for air, water, soil, sediment <br />and plants. htontlily water samples must be taken at five locations upstream and <br />downstream of the operation and at three nearby wells. Water reports must tk~en be <br />submitted to the Health Department twice a year. Air quality must be monitored at <br />three locations for dotal suspended particulates and radioactive radon gas and must <br />be reported twice yearly. <br />The company plans to install a system of levees and drains to protect its fa- <br />cilities in the event of a 100-year flood, }fazle said, since the operation is in a <br />floodplain zone. <br />The Health Department's Water Quality Control Division revised and renewed the <br />wastewater discharge permit for the Schwartzwalder Mine last spring with input from <br />the Radiation Control Division, since about 600,000 gallons of treated wastewater <br />are discharged into Ralston Creek daily from the mining operation. <br />The mine's wastewater discharge permit requires daily monitoring and submitting <br />monthly reports to the water Quality Control Division which checks the results and <br />periodically takes samples to insure that the levels of pollutants are within the <br />limits of the permit. <br />For information about the Schwartzwalder license, contact Hazle at 320-833J, <br />ext. 6246. <br />---30--- <br />
