What is an Administrative Record?
An administrative record is a collection of documents which forms the basis for an agency's
decision, in this case the selection of a response action at a Superfund site.
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.
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 CD by calling the Superfund Records
Center at (415) 536-2000.
