CalEPA Vapor Intrusion Workshops
The California Environmental Protection Agency (CalEPA) Vapor Intrusion Workgroup (CalEPA VI Workgroup) is a multi-agency workgroup consisting of the Department of Toxic Substances Control (DTSC), the State Water Resources Control Board (State Water Board), the Regional Water Quality Control Boards, and the Office of Environmental Health Hazard Assessment (OEHHA) that serves as a technical and regulatory resource for addressing contaminated sites impacted by vapor intrusion across California. The CalEPA VI Workgroup is planning a series of public workshops to gain input on CalEPA’s efforts to evaluate vapor intrusion at contaminated sites. The Kickoff Workshop will be hosted via Zoom on July 24, 2025, from 9:00 a.m.-12:00 p.m. PDT – this will be a virtual-only workshop with no physical location.
