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) is currently using to identify appropriate remedial activities for the Indian Bend Wash South Superfund Site, Groundwater Operable Unit in Tempe, Arizona. It is presented in two media: the Compact Disk (CD) and 35 mm microfilm containing large format documents. The administrative record file is complete now that the public comments on EPA's Proposed Plan, EPA's response to comments, and the Amended Record of Decision (AROD) are included.
Two previous administrative records are included by reference in this groundwater remedy AR because documents in them were considered or relied on: the Indian Bend Wash South Superfund Site AR (1993 with supplements) and the Indian Bend Wash South Superfund Site DCE Circuits Subsite Removal Action AR (1994). These Administrative records are also available for viewing at this repository.

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