Top Takeaways From August MassDEP BWSC Meeting

MassDEP’s Bureau of Waste Site Cleanup (BWSC) held an Advisory Committee meeting on August 15, 2024. Click here for the meeting agenda and click here for slides from that meeting.

Representatives of LSPA’s Regulations Committee attended the meeting and provided the following top takeaways (in no particular order):

  • MassDEP continues to work on a draft policy (the so-called “Comm-24” policy) which would specify the parameters which must be met to allow contaminated soil from one MCP site to be reused at another MCP site. This draft policy is expected to be available for public review and stakeholder engagement before the end of 2024.
  • MassDEP is drafting a PFAS Q&A document using questions posed by external stakeholders and internal MassDEP staff. Topics include: Standards; MCP Notification; Site Assessment; Risk Assessment; Treatment; Analysis; and Downgradient Property Status.
  • MassDEP met separately with the LSPA and National Grid in July to discuss some areas of the revised MCP Q&A. As a result, MassDEP will be clarifying Coal Tar Waste Deposit definitions and requirements. EPC determinations are being revised as well. 
  • The Commonwealth has two years to comply with EPA’s new PFAS MCL. BWSC is coordinating its efforts to promulgate MCP cleanup standards with the standards being developed by the Drinking Water Program. 
    • MassDEP is considering changes to the current Imminent Hazard concentration of greater than or equal to 90 ng/L for PFAS 6. 
    • MCP soil standards are not expected to change significantly. 
    • MCP standards for reportable concentrations (i.e., RCGW-1) and Method 1 risk standards (i.e., GW-1) will reflect changes to the MassDEP Drinking Water Program’s drinking water standards.
    • Because EPA drinking water standards include PFAS compounds not currently covered by MassDEP PFAS6 drinking water standards and MCP cleanup standards, MassDEP will include these additional PFAS compounds in its standards.
    • Until new Massachusetts PFAS standards are finalized, the current PFAS standards remain in effect.
    • If you have PFAS Program questions or comments, please contact: John Ziegler, PFAS Coordinator, MassDEP-BWSC, (617) 874-6733; [email protected].
  • A Western MA Brownfields Roundtable will take place on Sept. 17, 2024, from 9:00 am to12:30 pm at the offices of the Pioneer Valley Planning Commission in Springfield, MA. For more information, contact David Foss, MassDEP’s Statewide Brownfields Coordinator, at [email protected].
  • Data Management Update: eDEP forms have been updated based on the 2024 MCP Revisions. A new version of the Site File Viewer was released in July 2024. If you have questions about Searchable Sites, eDEP, or the File Viewer, contact [email protected].
  • The next MassDEP BWSC Office Hours Meeting will be Thursday, Sept. 19 at 9:00 am. The next BWSC Advisory Committee Meeting will be Thursday, November 21 at 9:00 am. More details here.
