  • Mining and Mineral Processing Sites - US EPA

    The main asbestos tailings pile is located in the east fork of Pine Canyon Creek. Erosion has created gullies 15 feet wide and 10 feet deep in the down slope of the tailings pile despite the presence of a small dam below the tailings pile. The main contaminant of concern is chrysotile asbestos.
