EPA to Issue Guidance on Petroleum Vapor Intrusion this YearSeptember 20, 2012
The Environmental Protection Agency (EPA) says it will issue final guidance specifically addressing petroleum vapor intrusion by late 2012. According to the EPA, the issue will be made in conjunction with broader vapor intrusion guidance from the Office of Solid Waste and Emergency Response.
Christopher Roe told BNA newly updated vapor intrusion guidance from New Jersey, which treats petroleum contamination less strictly than other sources of contamination, might provide a model approach for the final EPA guidance on petroleum vapor intrusion. He commented that final guidance should bring a consistent approach to vapor intrusion regulation across all EPA regions.
Roe believes that regions are making individuals decisions about what constitute sufficient investigation of this pathway, causing inconsistency and uncertainty. He says it will be helpful to have final guidance for EPA.
