While not formally a part of the MassDEP Reg Reform initiative, the Bureau of Waste Site Cleanup is developing revisions to the Massachusetts Contingency Plan (310 CMR 40.0000) related to the vapor intrusion pathway. This work is being conducted in consultation with the existing Indoor Air/VI Workgroup and documented on the Indoor Air Project blog at http://indoorairproject.wordpress.com.
- There will be a Waste Site Cleanup Advisory Committee meeting on Thursday, June 27th from 9:30 am to noon at MassDEP’s Boston Office, One Winter Street, 2nd floor conference rooms A & B. The first ½ hour of the meeting will provide general program updates. From 10 am to noon we will hold a discussion on the public comment we’ve received on the Active Pathway Elimination Measure proposal (the proposed changes that provide for a Permanent Solution with Conditions where a subslab depressurization system is operated as to prevent vapor intrusion impacts to a building as part of a permanent solution). This portion of the meeting is intended to assist MassDEP in developing the final amendments for this closure option through more focused discussion of the different procedural and technical requirements proposed in the public hearing draft. A list of topics to be covered by this discussion will be sent ahead of the meeting.
