MassDEP has released the following guidance documents for public comment by the waste site cleanup community in Massachusetts. LSPA members are welcome to submit comments to the LSPA for inclusion in our comment letter or directly to MassDEP.

Characterization of Petroleum Contaminated Sites:
MassDEP has posted a new Public Comment Draft document for petroleum contaminated sites. The draft document is an update to the “Characterizing Risk Posed by Petroleum Contaminated Sites: Implementation of the MADEP VPH/EPH Approach,” dated October 31, 2002.

The following LSPA practice tip was introduced at the April 2026 Membership Meeting, which was held via Zoom on Tuesday, April 14, 2026, from 3:45-5:00 PM.

Practice Tip  
There can be more than one LSP-of-Record for a disposal site. As defined in the MCP (310 CMR 40.0006), an LSP-of-Record is an LSP “…who has rendered an LSP Opinion [at a] site, …”  and remains as such until they provide written resignation to MassDEP. In cases where there are multiple LSPs-of-Record, it may be beneficial to coordinate activities with other parties performing response actions.  

The LSPA received the following email from MassDEP Bureau of Waste Site Cleanup on August 11, 2025: 

The final installment of the 2024 MCP Amendments Q&A has been posted as of August 11, 2025.

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.

The following LSPA compliance tip was introduced at the May 2024 Membership Meeting, which was held remotely on May 16, 2024 via Zoom.  

Compliance Tip of the Month
 The U.S. EPA has promulgated MCLs for PFAS in drinking water; states are required to establish their own regulations that are no less stringent than the federal standards within two years.

MassDEP’s deadlines for written comments have been extended to June 5, 2024 for both guidance documents currently posted on the MCP Amendments web page: “Risk Characterization Guidance, Chapters 1-5, Public Review Draft” and “Interim Guidance on Implementing Activity and Use Limitations.”

The two LSPA groups reviewing these guidance documents are still looking for comments. If you want to join the review group or have comments you wish to share on the Risk Characterization Guidance, please contact [email protected] by no later than May 9th.

In 2020, the LSPA formed a Climate Change Subcommittee (of the Technical Practices Committee) to consider how waste site cleanup practitioners might address anticipated MCP amendments on that topic. In 2022, the subcommittee produced and shared a Climate Change Toolkit. Now, the MCP Amendments are final and it’s time to start using the toolkit! 

The new MCP includes climate change-related language in specific sections on these topics:
