About the Records Center

The Region 10 Superfund Records Center - staffed by ASRC Primus, Inc. - is a secure, centralized storage and processing facility for Superfund program documents. The collection includes:

  • Federal facilities site files
  • CERCLA site assessment files
Our facility includes a public viewing area for Dockets and Administrative Records, a stand-alone computer, and a microfilm reader/printer.

Superfund Administrative Records

    Administrative Records (ARs) are collections that document cleanup decisions related to specific National Priorities List (NPL) and Removal Response actions. Administrative Record files are available for public review at the Records Center. Though not required, an appointment for review is recommended in order to guarantee availability of time and review space.
Hazardous Waste Compliance Dockets

    The Records Center houses the Hazardous Waste Compliance Docket files, portions of which are available for public viewing. This docket is comprised of federally owned and/or operated sites which are being reviewed and tested for possible inclusion on the National Priorities List (NPL). Review appointments are recommended.
NPL, Removal Response, Federal Facilities, and Site Assessment Records

    The Records Center also houses documents pertaining to Superfund sites which are not included in the Administrative Record collection. An appointment and a Freedom of Information Act request are required to review these documents. Please submit your FOIA request in advance, as this allows time to determine which records are responsive to your request, and to arrange scheduling of your review. See below for information about making FOIA requests and review scheduling.
Freedom of Information Act (FOIA) Requests

    FOIA requests must be made prior to a review of all records, except for those designated as "Publicly Available Records." For more information on submitting FOIA requests, including electronic FOIA request submissions, visit our Region 10 FOIA page.

    Copies of requested documents will be mailed to the requester. The FOIA page contains information regarding FOIA fees.
