The Navy issued a report known as the “Environmental Conditions of Property” report. This report summarizes the historical, cultural, and environmental conditions of the property and contains a summary of the current status of the IRP and MMRP programs. The report indicates that known or suspected areas of environmental contamination are present on less than 1,200 acres of the 5,170 acre site. These areas consist of approximately 60 specific locations where past releases of hazardous substances to soil and groundwater are either suspected or are known to have occurred. These locations are currently in various stages of study, cleanup and monitoring.
A local information repository has been established by the Navy to facilitate community access to reports prepared to date on environmental conditions and cleanup activities at the Concord Naval Weapons Station. The information repository is located at the Concord Public Library, located at 2900 Salvio Street in Concord, CA. The entire Administrative Record File for the Concord Naval Weapons Station is maintained at the Naval Facilities Engineering Command Southwest, 1220 Pacific Highway, San Diego, CA 92132.
The cleanup process is overseen by several federal and state environmental regulatory agencies. To facilitate this oversight, investigation and cleanup activities are discussed at monthly Remedial Project Managers meetings comprised of representatives from the Navy, the City, the U.S. Environmental Protection Agency (EPA), the California Department of Toxic Substances Control (DTSC), the Regional Water Quality Control Board (Water Board), and other federal and state agencies.
The Navy always retains liability for any discovery of additional contamination at an identified site or at an unknown site.
