CHAAP Archive Repository
The Cornhusker Army Ammunition Plant Archive Repository, required by the Code of Federal Regulations, is a compilation of documents that track the discovery, investigation, and remedy selection for environmental clean-up activities. It also provides a mechanism for public participation. The documents contained in the Archive Repository were used as the basis for the selection of a response action. All hard copies of the Archive Repository reside at the Grand Island Public Library. Electronic copies of the project documents can be accessed below. You can also download a description of the Comprehensive Environmental Response, Compensation and Liability Act Phases.
