Administrative Record Index

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

The documents contained in this administrative record were used by U.S. Environmental Protection Agency (EPA) to identify and select the appropriate remedial activities for the Tucson International Airport Area Superfund Site, Airport Property Soils and Shallow Groundwater Operable Unit, which also includes soils at the Burr-Brown and former West Cap properties.
The administrative record has been added to as documents have become available. The original compilation, dated April 13, 1994, consists of documents AR #1 - AR #64; Supplement 1, dated June 16, 1997, consists of AR #65 - AR #610; Supplement 2, dated July 18, 1997, consists of AR #611 - AR #612; and Supplement 3, dated December 31, 1997, consists of AR #613 - AR #638. The cumulative index presents the records in chronological order.

Key documents in this administrative record are the Remedial Investigation Report (AR #576 and AR #577), the Feasibility Study (AR #607), the Proposed Plan (AR #611) and the Record of Decision (AR #636 and AR #637). The list of U.S. Environmental Protection Agency guidance documents that were considered or relied upon in the selection of the remedy is document AR #63. Copies of the guidance documents are contained in the Compendium of CERCLA Response Selection Guidance Documents located in the Superfund Records Center.

Documents AR #37, AR #620 and AR #622 are audiocasettes, computer disks or otherwise in formats not suitable for microfilming; they are available for review at the Superfund Records Center in San Francisco.
