EBC Site Remediation and Redevelopment Committee
June 23, 2009 @ 8:00 am - 9:30 am
Impacts to air within buildings may occur at sites where subsurface soil or groundwater contains volatile contaminants and these contaminants migrate through soil vapor and building foundations into indoor air (i.e., vapor intrusion).
Recently, there has been increased focus on vapor intrusion issues both in the transaction and in the site cleanup context. This increased focus is driven by two fundamental factors which can be summed up in two words: risk and uncertainty. The risk: Some of the contaminants that can affect indoor air pose risks to human health at fairly low concentrations. The potential for human health risks may increase public scrutiny, potential response costs, and legal exposures. The uncertainty: Many regulators are concerned that existing tools may not accurately predict concentrations of contaminants in indoor air. At the same time, the regulated community is concerned that indoor air testing may result in false positives caused by ordinary residential activities.
This risk/uncertainty combination is playing out right now in three important ways: First, several jurisdictions are currently re-evaluating or already have re-evaluated closed sites that may pose vapor intrusion concerns, and in some cases have required potentially responsible parties — many years later — to conduct additional work. Second, several jurisdictions are re-evaluating the current regulatory programs to ensure that vapor intrusion is conservatively addressed on a moving forward basis. Third, the regulated community is trying to continue response actions at affected sites and/or evaluate properties for purchase or redevelopment during this time of great uncertainty.
In Massachusetts, the DEP has undertaken an extraordinary effort to provide comprehensive guidance to the regulated community on how to address vapor intrusion at sites. DEP launched an ?Indoor Air Workgroup? comprised of DEP staff, environmental consultants, lawyers, and other interested parties, to work through these issues. DEP has stated that it intends to issue comprehensive guidance by the end of 2009, an aggressive goal.
Please join us as we discuss these important issues. Elizabeth Sherwood Krol, P.G., from Shaw Environmental & Infrastructure, Inc., will discuss the national picture, including what the 2008 ASTM standard on vapor intrusion requires and how it is being used in the marketplace. Gerard Martin, Chief of the Site Management and Enforcement Section of the Bureau of Waste Site Cleanup at the Southeast Regional Office (Lakeville), DEP, will discuss why DEP has launched the indoor air workgroup, what the goals of the workgroup air, and some of the key issues that have been discussed in the workgroup. Ileen Gladstone, P.E., LSP, LEED AP, from GEI Consultants, Inc., will discuss, using a case study, how vapor intrusion issues are playing out at sites across the state.
