Description of Contamination: Approximately 300,000 pounds of magnesium at the facility
caught fire on January 14, 2005 and continued to burn for approximately 48 hours. The fire and
smoke acted as a propellant for encapsulated asbestos insulation located atop a rubber membrane
roofing material used in the facility buildings, built around 1969. As a precaution, a 1-mile
radius around the AMACOR facility was evacuated, involving 5,000 to 8,000 residents. Asbestos
removal activities on affected residential areas in Anderson, Indiana have been taking place since
the fire. Asbestos has been detected in some debris that fell in the neighborhood south and
southwest of the facility.
