The following LSPA compliance tip was introduced at the September 2025 Membership Meeting, which was held in-person at the DoubleTree Hotel in Westborough, MA on Wednesday, September 17, 2025, from 5:30 - 8:00 PM.

LSPA Practice Tip of the Month
It is important LSPs check the correct boxes when submitting MCP documents. MassDEP has noted two examples where LSPs frequently check incorrect boxes: (1) When a Permanent or Temporary Solution Statement (PSS or TSS) has been retracted for any reason (pursuant to a Notice of Noncompliance or other), a new PSS or TSS is required and so, LSPs should not indicate they are submitting a revised PSS or TSS when they submit the new PSS or TSS; and (2) When putting a site into Remedy Operation Status (ROS), LSPs need to check box #17 when they submit their ROS Opinion, otherwise the MassDEP database will not reflect that the site has transitioned to ROS. If you have questions about BWSC forms, contact [email protected].

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 following LSPA compliance tip was introduced at the June 2025 Membership Meeting, which was held via Zoom on Wednesday, June 11, 2025, from 3:45 PM - 5:00 PM.

Compliance Tip  
When OHM from an upgradient source migrates onto a disposal site being addressed for other releases, and regardless of whether DPS has been established, that OHM must be included when evaluating risk and/or otherwise seeking to achieve a Permanent Solution for the disposal site. OHM from an upgradient source is not considered “background” and, for example, cannot be excluded as a contaminant of concern.

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.

The Massachusetts Department of Environmental Protection (MassDEP) Bureau of Waste Site Cleanup is holding an online informational meeting about upcoming Technical Assistance Grants (TAGs) funding. TAGs are available to community and municipal groups to enhance public participation in assessment and cleanup activities at oil or hazardous material disposal sites. TAGs may be used to obtain expert advice and technical assistance and to promote community education for qualifying projects.  The informational meeting will include a presentation on the purpose of the TAG program, grant eligibility requirements, and the grant application process and timelines.

The online informational meeting will take place on Wednesday, April 16, 2025 at 4:00 PM via Zoom. You may access the meeting via MassDEP’s TAG webpage at this link:  https://www.mass.gov/info-details/technical-assistance-grants-waste-site-cleanup

On March 19, 2025, Annual Certification letters were sent by MassDEP’s Bureau of Waste Site Cleanup to property owners where an Active Exposure Pathway Mitigation Measure (AEPMM) is required to maintain a Permanent Solution with Conditions under the Massachusetts Contingency Plan (MCP). The MCP requires that the current property owner submit an annual certification concerning the operation and maintenance of the AEPMM upon receipt of a form sent by MassDEP (310 CMR 40.1025(8)).

In addition to the annual certification, MassDEP is requesting that the property owner conduct a shutdown and restart test (310 CMR 40.1025(9)) to demonstrate the remote telemetry for the system is operating correctly. In total, seventy-four (74) letters were sent to property owners. Letters were also emailed when MassDEP had an email on file for the property owner. The deadline for returning the Annual Certification form is May 5, 2025. Annual Certification letters sent by MassDEP are publicly available on the Energy & Environmental Affairs Data Portal.  As MassDEP receives completed forms from property owners those letters will be added to the Data Portal as well. 

The following LSPA practice tip was introduced at the March 2025 Membership Meeting, which was held via Zoom on March 20, 2025.

Practice Tip of the Month
Spring is a good time to document the condition of monitoring wells, especially after a busy snowplow season. Well covers that are damaged over the winter may no longer meet the requirements of 310 CMR 40.0028, which specifies:

The MCP-mandated March 1, 2025 deadline is fast approaching.

Pursuant to 310 CMR 40.0560(7)(i)(4.)(b), a Periodic Review of the Temporary Solution and Tier Classification Extension shall be submitted within one year of March 1, 2024 for disposal sites where Active O&M is not occurring and the following apply: (i) a Temporary Solution Statement for a disposal site was submitted to the Department prior to March 1, 2024; (ii) the Tier Classification had expired prior to March 1, 2024, and (iii) Status Reports and, as applicable, the Periodic Review of the Temporary Solution had not been submitted at the frequency specified pursuant to 310 CMR 40.0898 and 310 CMR 40.1050(4) prior to March 1, 2024.

The following LSPA practice tip was introduced at the February 2025 Membership Meeting, which was held via Zoom on February 12, 2025.

Practice Tip of the Month
When an MCP submittal form is required, you should download the form directly from the MassDEP website. That way you will have the most current version of the form rather than a possibly outdated version saved to your desktop or laptop.

2024 flew by while the LSPA advocated for the waste site cleanup practice and supported practitioners throughout the Commonwealth. We are always eager to review and assess our annual accomplishments and this year is no different. We can’t say “thank you” enough to LSPA members, committees, workgroup leaders, and committee chairs who make this association successful. We also applaud our annual and event sponsors who underwrite our work; we appreciate your confidence in our ability to carry out our mission. Below are some 2024 highlights.  

The following LSPA compliance tip was introduced at the December 2024 Membership Meeting, which was held via Zoom on December 18, 2024.

Compliance Tip of the Month
While the MCP requires an assessment of “reasonably foreseeable future changes in site conditions” related to climate change, it does not indicate a specific assessment timeframe. 

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.
