| Environmental Factors | THERE WERE NO TAILINGS ON SITE. THERE WAS ONE DISCHARGING ADIT WHICH ENTERED BELT CREEK. MAXIMUM CONTAMINANT LEVELS WERE EXCEEDED FOR CADMIUM, NICKEL, AND ANTIMONY IN THE ADIT DISCHARGE. BELT CREEK FLOWED IMMEDIATELY ADJACENT TO THE SITE. OBSERVED RELEASES TO BELT CREEK WERE DOCUMENTED FOR CADMIUM, COPPER, IRON, MANGANESE, NICKEL, LEAD, AND ZINC. THE MAXIMUM CONTAMINANT LEVEL FOR NICKEL WAS EXCEEDED IN THE DOWNSTREAM SAMPLE, WHICH WAS DIRECTLY ATTRIBUTABLE TO THE SITE. THERE WAS ONE OPEN ADIT, NUMEROUS HAZARDOUS STRUCTURES, AND HIGHWALLS ON SITE. |
