EPA Affirms Arc Ecology Position on Dust

U.S. EPA has finalized the report entitled, “U.S. EPA's Final Review of Dust/Naturally Occurring Asbestos Control Measures and Air Monitoring at the Former Hunters Point Naval Shipyard (June 9, 2025).”

The link to the final document appears at the bottom of this post.

About the Report:
·        EPA conducted a technical review of dust mitigation plans and an independent laboratory analyses of data associated with the City and Air District’s efforts to control naturally-occurring asbestos and dust associated with construction activity on Parcel A at the former Hunters Point Naval Shipyard. EPA also evaluated metals and radiation data for both the Parcel A development work and Navy activities on the Shipyard.  
·        EPA made independent technical advisory services available to community members to review the data and EPA’s draft report.  EPA held a public meeting for the community to hear comments from the technical expert.  The comments and EPA’s responses are attached to the final report.  
·        Naturally-occurring asbestos in dust at construction sites is a widespread concern in California where serpentine soil is common.  EPA’s report finds that best practices for dust monitoring and mitigation are in place at Parcel A and the Hunters Point Shipyard to protect the community by keeping exposures to asbestos, metals and radiation in dust within acceptable levels.
