  • Vapor: Intrusion into Redevelopment

    Wednesday, December 11, 10:45 am - 11:45 am
    515 A
    Town Meeting Conversations
    Track 6: Liability and Enforcement
    This session will discuss challenges in completing vapor intrusion (VI) assessments while regulatory guidance documents from two California state agencies (the State Water Resources Control Board and the CA Department of Toxic Substances Control) are in flux. Varying opinions by state regulators on the appropriate path forward at VI sites has made it difficult to make risk-based decisions for site cleanup, especially where redevelopment is planned. The discussion will also include evaluation of appropriate attenuation factors, site-specific cleanup levels, monitoring requirements, and mitigation.
