Administrative Record

IAAAP Administrative Record, 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 Administrative Record were used as the basis for the selection of a response action. All hard copies of the Administrative Record reside at the installation. For a complete list of every document, download the Administrative Record Index – OCT 2022. You can also download a description of the CERCLA Phases.
