LSPA Introduces December 2021 Compliance Tip of the Month

The following LSPA compliance tip was presented at the December 2021 Membership Meeting, which was held virtually through the Zoom webinar platform, on December 14, 2021.  

Compliance Tip:
When using a Method 2 or Method 3 risk characterization to establish a condition of NSR, you must consider reasonably foreseeable, as well as current, site activities and uses. In particular, future vapor intrusion exposures could result from changes in building use or altered building conditions. Potentially problematic activities and uses can be eliminated from consideration in the risk characterization through an appropriate AUL, per 310 CMR 40.0923(3)(b).
