Updated Compendium of Analytical Methods (CAM) protocols for Perchlorate, WSC – CAM – VIII B, Analysis of Perchlorate by Ion Chromatography (IC) with Electrospray Ionization/Mass Spectrometry (ESI/MS or ESI/MS/MS) or High Performance Liquid Chromatography (HPLC) with ESI-MS or ESI-MS/MS, have been posted to MassDEP’s web site at https://www.mass.gov/info-details/compendium-of-analytical-methods-cam#high-performance-liquid-chromatography-hplc-and-ion-chromatography-methods

Dear LSPA Member,

As the voice of LSPs and environmental practitioners across Massachusetts, the LSPA is actively advocating to strengthen our profession and advance sound environmental policies. Below is a summary of what we’ve been working on recently:

The LSPA received the following email from MassDEP Bureau of Waste Site Cleanup on June 30, 2025: 

MassDEP has published a number of new Compendium of Analytical Methods (CAM) protocols and materials at https://www.mass.gov/info-details/compendium-of-analytical-methods-cam.

The MassDEP Bureau of Waste Site Cleanup (BWSC) has released its revised Policy for “Off-Gas Treatment of Point-Source Remedial Air Emissions” (formerly Policy #WSC-94-150), with a public comment period ending on June 30, 2025.

This Policy concerns air emissions that occur as a result of air stripping of contaminated groundwater, vacuum extraction of soil gases, or any other remedial activity conducted pursuant to MGL Chapter 21E that creates a point-source discharge of contaminants to air. The intent of this Policy is to articulate when off-gas treatment of point-source remedial air emissions may not be necessary to protect human health, safety, public welfare, and the environment.

BWSC Advisory Committee Meeting Highlights

MassDEP’s Bureau of Waste Site Cleanup (BWSC) Advisory Committee meeting was held on November 21, 2024. The meeting agenda, meeting slides, and a YouTube meeting video are all available here. The LSPA’s key takeaways are below.

• AUL Guidance is “nearing the finish line” and expected to be final by early 2025. MassDEP is continuing to review and incorporate comments received, and ensuring consistency with other documents – e.g., Risk Characterization guidance. Contact Margaret Shaw at [email protected] with questions.
• Soils Reuse Update: The COMM-24 Soils Policy is currently under review by MassDEP senior staff. This policy would allow reuse of contaminated soils at other 21E sites at levels greater than currently allowed by COMM-15. There will be a public review of the draft policy before it is finalized. At this time, major acceptance requirements include but are not limited to: must result in achievement of a Permanent Solution, must include a public involvement process, and at least 250,000 cubic yards of soil must be moved.  
• The PFAS Q&A is under review by senior staff and expected to be released in early 2025.  For PFAS questions, contact John Ziegler, LSP, at [email protected].
• The Western Regional Office has a new Deputy Regional Director (DRD): Tamara Cardona-Marek, Ph.D. She replaces Catherine Skiba who was the most recent Acting DRD.

On September 10, 2024, the LSPA sent our comments to MassDEP’s Bureau of Waste Site Cleanup (BWSC) as part of its public comment period on Risk Characterization Guidance, Chapters 6-10, Public Review Draft.

The LSPA adhered to our typical process for collecting and submitting comments on draft documents:

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.

Notes from BWSC Advisory Committee

MassDEP’s Bureau of Waste Site Cleanup Advisory Committee met on October 27, 2022 for several hours. Typically, MassDEP posts the slides and recordings of Advisory Committee meetings here. At this time, these have not yet been posted.

A brief summary of meeting highlights is provided below.

The Department of Environmental Protection (MassDEP) is holding a listening session on disposal capacity issues for contaminated soil coming from Massachusetts disposal sites (“contaminated” soil meaning concentrations > RCS-2).  This session will help MassDEP better understand the scope and impact of contaminated soil disposal issues and identify possible avenues for addressing them. 

The listening session is planned for December 16 from 10:00 am to 12:00 pm, to be held via Zoom, and hosted by MassDEP’s Liz Callahan (Acting Assistant Commissioner, Bureau of Waste Site Cleanup), Greg Cooper (Division Director, Business Compliance & Recycling), and Paul Locke (Acting Deputy Commissioner, Policy & Planning).
