About the Administrative Record
This administrative record contains the documents that the U.S. Environmental Protection Agency (EPA) used to determine that no further action is necessary at the San Fernando Valley Verdugo Study Area Superfund Site in Los Angeles County, California. It is presented in two media: the Compact Disk (CD) and a companion binder of large format documents. The administrative file for the ROD is complete now that EPA has issued the ROD after a public comment period. No public comments were submitted on the Proposed Plan.

EPA welcomes questions and comments on documents contained in the administrative record file. Please contact:
