Welcome to the CHAAP Environmental Restoration Website


Cornhusker Army Ammunition Plant (CHAAP) is located west of Grand Island, Nebraska, north of Interstate 80 and 2 miles west of Nebraska Highway 281, on an 11,936-acre tract. The site includes an off-post area (to the northeast) consisting of groundwater impacted by explosives compounds which originated at CHAAP during the production of artillery shells, mines, bombs, and rockets during World War II, and the Korean and Vietnam conflicts. The plant operated intermittently from 1942 to 1973. The installation was inactivated in 1974 and declared excess in 1989. It is in the process of being transferred back into the local county property tax rolls. Transfer and sales of tracts back into private ownership began in 2001.

CHAAP has periodic Public Meetings to review past actions and give status updates regarding ongoing environmental investigation and restoration activities. Community members are invited and encouraged to attend these meetings. Public meetings are attended by the U.S. Army Corps of Engineers, U.S. Environmental Protection Agency, Nebraska Department of Environment and Energy, and other local stakeholders.
