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) used to identify appropriate remedial activities for use at the Apache Powder Co. Superfund site, St. David, Arizona. It is presented in Compact Disk (CD) format. The administrative record file will be updated periodically. The current update to the Apache Powder Co. administrative record will be complete after public comments on EPA's Proposed Plan, EPA's response to comments, and the amended Record of Decision are included in a future update.
The administrative record supports the Record of Decision (ROD), dated September 30, 1994 (Doc # 88001234); the proposed Explanation of Significant Differences (ESD) #1, dated April 16, 1997 (Doc #88001314); ESD #2, dated September 29, 2000 (Doc #90560); and the Proposed Plan, dated July 2005 (Doc #2066325).

The four lists of U.S. Environmental Protection Agency guidance documents which were considered or relied upon in the selection of the remedy are documents #88000981, #88002997, #88003313, and #2066324 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.

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