Vapor Intrusion: Opportunity for Comment with EPA

Last month, the Environmental Protection Agency published a notice for “Public Comment on the Development of Final Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway From Contaminated Groundwater and Soils (Subsurface Vapor Intrusion Guidance)” in the Federal Register. The draft of the Subsurface Vapor Intrusion Guidance was initially released for comment during 2002 and the EPA is planning on issuing final guidance by November 20, 2012.
