About the Administrative Record
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 Anaconda
Copper Mine Superfund site, Arimetco Operable Unit 8 in Yerington, Nevada. It is presented in
digital video disc (DVD) format. The administrative record file will be supplemented
periodically; it will be complete after public comments on EPA's Proposed Plan, EPA's response
to comments, and the Record of Decision (ROD) are included.
EPA welcomes questions and comments on documents contained in the administrative record
file. Please contact:

What is an Administrative Record?
An administrative record is a collection of documents that forms the basis for an agency's
decision, in this case the selection of a response action at a Superfund site. This does not mean
that only documents that support a response decision are placed in the administrative record.
Relevant documents that were relied upon in selecting the response action, as well as relevant
documents that were considered but ultimately rejected, are included. The administrative record
also acts as a vehicle for public participation in selecting a response action.
Under section 113(K) of the Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA), as amended by the Superfund Amendments and Reauthorization Act
(SARA), the U.S. Environmental Protection Agency (EPA) is required to establish an
administrative record for every Superfund response action and to make a copy of the
administrative record available at or near the site. The administrative record must be reasonably
available for public review during normal business hours. Questions regarding the maintenance
of the administrative record file should be directed to:
Elaine Chan, Administrative Record Coordinator, U.S. EPA (SFD-7-5), 75 Hawthorne Street,
San Francisco, CA 94105-3972, Phone: (415) 972-3128
How to obtain copies of administrative record documents:
Individuals may copy any documents contained in the administrative record file according to the
procedures at the local repository or request a copy of the DVD by calling the Regional Records
Center at (415) 947-8717.
