The Installation Restoration Program (IRP) at Naval Weapons Station Seal Beach began in 1985 with an Initial Assessment Study in which 25 locations of potential contamination were identified. A further Resource Conservation and Recovery Act Facility Assessment in 1989 and subsequent discoveries brought this total up to 76 locations. During the course of these and later studies, 49 sites were determined to contain no significant contamination, five currently operating, permitted facilities were removed from the program, and two additional sites were transferred to other environmental programs specializing in underground storage tanks. Fifteen sites have had cleanup actions completed. The remaining five IRP sites are in various stages of active study or cleanup.

A Military Munitions Response Program (MMRP) Preliminary Assessment was conducted in late 2008, with five MMRP sites recommended for Site Inspections. As a result of these investigations two sites were recommended for no further action and remaining three sites will undergo more detailed analysis. 

The station has an active Restoration Advisory Board.  For a map of cleanup sites click here
