EPA is inviting the public to provide comments on the development of final guidance for Evaluating Vapor Intrusion to Indoor Air Pathway from Contaminated Groundwater and Soil (Subsurface Vapor Intrusion Guidance). A draft version of the Subsurface Vapor Intrusion Guidance was released in November 2002 (67 FR 71169), and a docket was established for public comments: Docket ID No. EPA-HQ-RCRA-2002-0033. The 2002 draft is available from the docket (http://www.regulations.gov) and at: http://www.epa.gov/epawaste/hazard/correctiveaction/eis/vapor.htm.
EPA is planning to issue the final Subsurface Vapor Intrusion Guidance by November 30, 2012 and has re-opened the docket for public comment. Comments previously provided to the docket on the 2002 draft of the Subsurface Vapor Intrusion Guidance, and any comment provided to the docket before May 14, 2011, will be considered in the development of the final document. The public will also be given an opportunity to provide comments on a new draft of the guidance in the spring of 2012. Details on how to provide new comments to the docket are provided under ADDRESSES.
EPA has prepared a document entitled Review of the Draft 2002 Subsurface Vapor Intrusion Guidance, which summarizes EPA's current understanding of the portions of the 2002 Draft Subsurface Vapor Intrusion Guidance that remain valid and those that may need to be updated. In addition to updating portions of the 2002 draft, EPA plans to incorporate the following information at the recommendation of its Inspector General (Report No. 10-P-042):
- Updated toxicity values;
- A recommendation(s) to use multiple lines of evidence in evaluating and making decisions about risk from vapor intrusion;
- How risk from petroleum hydrocarbons should be addressed;
- How the guidance applies to Superfund Five-Year reviews;
- When or whether preemptive mitigation is appropriate;
- Operations and maintenance of mitigation systems, the termination of the systems, and when institutional controls and deed restrictions are appropriate.
The public may want to provide comments on the 2002 draft Subsurface Vapor Intrusion Guidance, the information that the Inspector General has suggested incorporating into the final guidance, or other information that EPA should consider when developing the final version of the guidance.
Vapor intrusion can occur when there is migration of volatile chemicals from contaminated groundwater or soil into a building. Volatile chemicals may include volatile organic compounds, select semi-volatile organic compounds, and under certain conditions some inorganic compounds, such as elemental mercury, radon, and hydrogen sulfide. Additional information about vapor intrusion can be found at http://www.epa.gov/oswer/vaporintrusion.
