In 1980, Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), better known as Superfund, mandating EPA to identify, investigate, and clean up abandoned hazardous waste sites throughout the country. For more than twenty years, EPA's Superfund program worked to fulfill this mandate in cooperation with various stakeholders.

On this Web site, EPA's Pacific Southwest Region Superfund Program publishes important documents on Superfund sites in the region (Arizona, California, Hawaii, Nevada, and Pacific Islands).

Information by site

Site Overviews: This includes, for each Superfund site in the region, a general description of the site, its history, progress, and contacts for more information. For certain sites, additional information is available, including some of the document types listed below.

All cleanup sites by state: from this page, you can view all Region 9 cleanup sites in progress. This list includes RCRA Corrective Action Sites, Brownfields, and more.

Information by document type

This information is sorted by document type. The information available here is also available through the "Site Overviews and Information" section above. However, this collection is less comprehensive than above set. Our goal for the future is to provide as much of the frequently sought information as possible.

Administrative Record Indices: listings of documents that support EPA's major decisions on site cleanups.

Fact Sheets: newsletters describing important site cleanup milestones. These are provided as attached Portable Document Format (PDF) files, with instructions for using them.

Records of Decision: the full text of Records of Decision (RODs) for site cleanups.

Images: photographs and other images of Superfund cleanups.

Maps: geographic information on contaminants and other aspects of Superfund cleanups.

Legal Documents: administrative and judicial agreements and administrative orders.

The Superfund Records Center can provide paper copies of releasable documents that are not yet available on the Web. Learn more about requesting a Superfund site file document.
