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 response activities for the Leviathan Mine Superfund Site in Alpine County, California. It is presented in Compact Disk (CD) and the documents can be accessed using Adobe Acrobat Reader.

EPA's decision, including public comments and responses to the comments, is presented in the EE/CA Approval and Non-Time Critical Removal Action Memorandum, dated July 12, 2005 (Doc # 2069500) on the CD.

This administrative record file also includes administrative record documents of all seven previous EPA removal actions at the Leviathan Mine Site, which are dated September 24, 1997, July 19, 2000, July 5, 2001, July 27, 2001, July 11, 2002, July 28, 2003, and July 29, 2004.
