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) used to identify appropriate remedial activities for the San Gabriel Valley Superfund site, Suburban Water Systems/Bartolo Well Field Operable Unit in Los Angeles County, California. It is presented in microfilm format. The administrative record supports the September 1988 Record of Decision (ROD) and the September 22, 1993 amendment to the Record of Decision.
This administrative record file also includes by reference the documents in the San Gabriel Valley Superfund Site, Whittier Narrows Operable Unit Administrative Record, August 31, 1992-January 4, 2000.
Several voluminous documents, such as sampling data, chain of custody forms, and quality control/quality assurance documentation for validated data are incorporated in the administrative record by reference. They are available for viewing at the U.S. EPA Superfund Records Center, 95 Hawthorne Street, San Francisco, CA 94105-3972, Phone: (415) 820-4700.
EPA welcomes questions and comments on documents contained in the administrative record file. Please contact:
