Administrative Record Index

To request copies of administrative record documents, an electronic order form is available.

This administrative record file contains the documents that the U.S. Environmental Protection Agency (EPA) relies on to identify appropriate remedial activities for the Tucson International Airport Area Superfund site, Area A and Area B Groundwater Operable Unit in Pima County, Arizona. It is presented in DVD format. The administrative record is complete now that public comments on EPA's Proposed Plan, EPA's response to comments, and the Record of Decision (ROD) and amendments are included.
This administrative record file also includes by reference the chain of custody forms used in the Tucson International Airport Area site cleanup project which are referred to in document ID #1132248. They are available for viewing at the US EPA Region 9 Superfund Records Center provided that 2 weeks’ notice is given for retrieval of the archived records.

EPA welcomes questions and comments on documents contained in the administrative record file. Please contact:
