K H Manufacturing (formerly Ken Hagen Manufacturing Co Inc) is a defunct corporation which conducted plastics molding research and design, manufacturing and assembly. K H Manufacturing was incorporated from 1956 until 2002.
The Town of Shelburn has coordinated redevelopment of several former Hagen buildings and parcels. Several parcels are unaddressed and remain as they were when the corporation was dissolved, including one building where the plastics research and development laboratory was located. Various hazardous substances that were used for research and development were never removed from the laboratory. The rooftop of the aged lab building began collapsing and the Town of Shelburn requested assistance for removal of the hazardous substances to the Indiana Department of Environmental Management (IDEM).
On November 5, 2018, the Indiana Department of Environmental Management (IDEM) requested assistance from the U.S. EPA. EPA has assigned an On-Scene Coordinator to oversee a removal action under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA).
