INTRODUCTION


TUCSON INTERNATIONAL AIRPORT AREA SUPERFUND SITE
AREA A & AREA B GROUNDWATER OPERABLE UNIT
ADMINISTRATIVE RECORD & CUMULATIVE INDEX

The documents contained in the original index and Supplements 1 and 2 of this administrative record were used by the U.S. Environmental Protection Agency (EPA) to identify and select the original, appropriate, remedial, cleanup requirements in EPA’s Record of Decision (ROD), dated August, 1988. EPA’s 1988 ROD addresses groundwater contamination (primarily trichloroethylene, or “TCE”) in what is referred to as Areas A and B of the regional aquifer located north of Los Reales Road at the Tucson International Airport Area Superfund Site (“Site”) in Tucson, Arizona.

Supplements to the administrative record file were added as documents related to remedy selection became available. (Note: Documents AR 56, AR 69 and AR 183.3 were removed from the original compilation, because they were determined either to be duplicates or not pertinent to this administrative record). The original compilation and all supplements are arranged in ascending chronological order. All supplements, with the exception of supplement 6, have undated documents at the end of each sequence.

The administrative record file was microfilmed in September 1994. At that time the index was edited to conform more closely with current Region 9 standards, and the title was made more specific (“Area A & Area B Groundwater Operable Unit”). Two essential documents were added to the file as Supplement 3: AR 1, which is the August 1988 ROD, and AR 2, which is comprised of the list of guidance documents considered or relied upon in the selection of the remedy.

Supplements 4-6 to this administrative record were microfilmed in August 2002. Supplement 4 consists of documents used by EPA to identify and propose changes to EPA’s 1988 ROD. These changes are documented in the EPA document, “Explanation of Significant Differences” (ESD 1). ESD 1 provides for changes to the groundwater remedy specifically in Area B-west (Air National Guard Base project area). At the end of the public comment period for ESD 1, the final ESD and supporting documents used by EPA were added to this administrative record as Supplement 5, dated March 14, 1997.

Supplement 6 to this administrative record contains documents used by EPA to identify and propose an amendment to EPA’s 1988 ROD and the 1997 ESD. The proposed “ROD Amendment,” as described in EPA’s Proposed Plan, dated June 2002, identifies contamination in the Area B of the Site (West-Cap and West Plume B) that was not characterized in the 1988 ROD and proposes the remedy to address this contamination. The list of EPA guidance documents which were considered or relied upon in the selection of the remedy in supplement 6 is document AR 65 in this administrative record file. Copies of the guidance documents are contained in the Compendium of CERCLA Response Selection Guidance Documents located in the Region 9 Superfund Records Center. Comments and responses to the Proposed Plan, the ROD Amendment itself, and any other documents used by EPA in formulating the ROD Amendment will be available in supplement 7 to this administrative record file.
