Today vapor intrusion sites qualify for the "Superfund" National Priorities List only if the risk from another pathway, such as drinking water, is considered serious. This rule, if finalized, would include vapor intrusion risk in the calculation of the Hazard Ranking System score. (Remember, however, that the score is a necessary but insufficient condition for listing sites on the NPL.}
Positive comments from the public would help move this major change forward. if you know of (real or potential) vapor intrusion (real or potential) sites that are inappropriately being addressed under voluntary cleanup programs or weak state regulatory programs, please describe those examples.

Lenny, Wanted to be sure you are aware the proposed rule that would add a subsurface intrusion (SsI) component to the Superfund Hazard Ranking System (HRS) was signed by the Administrator yesterday. We expect the rule will be published in the Federal Register in mid-February. Public comments on this proposed HRS SsI addition will be accepted on or before 60 days from publication in the Federal Register. You can find the proposed rule and supporting documents at www.regulations.gov (refer to docket number EPA-HQ-SFUND-2010-1086), and instructions for submitting written comments to the Agency. Please feel free to share this information with your networks. Thanks for all your support over the years to communities on vapor intrusion issues.
