MassDEP has submitted this seminar for the LSP Board's review and asked that it be certified for 2.0 hours of  "MassDEP Course" regulatory continuing education credit. A decision on that request is pending. This is a new course.

DESCRIPTION:

MassDEP was among the first states in the country to formally recognize the vapor intrusion pathway, via the development of Method 1 GW-2 standards in the 1993 Massachusetts Contingency Plan.

In the last 14 years, our scientific understanding of this pathway has evolved.  From a practical standpoint, the concern over this pathway has increased, especially since April 2006, when the MCP GW-2 standards for certain contaminants (e.g., PCE) were significantly lowered, which has in turn resulted in a significant increase in sites where the vapor intrusion pathway has been identified.  

The purpose of this interactive workshop is to discuss and attempt to integrate technological concepts, regulatory requirements, and standard of care issues. 

OUTLINE:

Specific topics will include:

• When to look for a vapor intrusion pathway
• Developing and evaluating Lines of Evidence
• Soil gas
• Indoor air
• Understanding and applying Typical Indoor Air Concentrations
• Critical Exposure Pathways
• Active commercial/industrial operations
• Remedial measures
