Vapor Intrusion Guidance public review draft is now available.

MassDEP is seeking public comment on its revised Vapor Intrusion 
Guidance draft.  This comprehensive draft document has been developed 
based on input MassDEP has received through discussions with the Indoor 
Air Workgroup and in other forums with LSPs, PRPs and other interested 
parties and written comments received on its July 2009 draft document.

MassDEP's goal in developing this guidance document is to provide clear, 
practical and health protective guidance on vapor intrusion assessment 
and mitigation approaches that are consistent with 21E and the 
Massachusetts Contingency Plan.  While parties conducting response 
actions may apply other approaches, provided they meet the requirements 
of the MCP, to address vapor intrusion sites, this draft reflects 
MassDEP's recommendations and expectations for adequately addressing 
this complex pathway and achieving a protective result.

MassDEP welcomes your comments on the scope, content, and 
readability/clarity of this draft.  Please consider and comment on the 
applicability of this guidance to vapor intrusion site work you have 
conducted or are conducting.  Please submit comments by replying to the 
blog post at MassDEP's Indoor Air Workgroup 
http://indoorairproject.wordpress.com/ by March 1, 2011. To facilitate 
MassDEP's review and consideration of comments, please reference page 
and section numbers when commenting on specific topics or text.
