| Environmental Factors | EROSION OF WASTE ROCK AND TAILINGS INTO DRAINAGES WAS OCCURRING. AN OBSERVED RELEASE TO CLANCY CREEK WAS DOCUMENTED FOR LEAD. OBSERVED RELEASES TO THE UNNAMED TRIBUTARY OF CLANCY CREEK WERE DOCUMENTED FOR ARSENIC AND LEAD. THE MAXIMUM CONTAMINANT LEVEL FOR CADMIUM WAS ALSO EXCEEDED IN THIS TRIBUTARY; HOWEVER, THE EXCEEDANCE COULD NOT BE ATTRIBUTED TO THE SITE. THE UNNAMED TRIBUTARY MADE UP LESS THAN 5 PERCENT OF THE FLOW OF CLANCY CREEK AT THIS LOCATION. |
