Liz Callahan is retiring from MassDEP after 38 years with the Waste Site Cleanup Program and stepping down from her role as Acting Assistant Commissioner, effective March 2, 2024. Liz joined MassDEP’s Northeast Regional Office in 1986 as an Environmental Analyst I and was thrilled a few years later to be part of the team that drafted and implemented the “new” MCP for the Commonwealth’s privatized cleanup program. Prior to serving as Assistant Commissioner, Liz worked in various BWSC roles in the Boston and Northeast Region, including as Division Director for Policy and Program Development, managing many rounds of MCP amendments.

Millie Garcia-Serrano will be taking over for Liz as BWSC’s Assistant Commissioner on March 2nd. Millie, who holds a Master’s in Public Health, brings a wealth of experience to her new position, most recently as the Regional Director of MassDEP’s Southeast Regional Office. Millie’s past experience includes serving as the President of the Association of State and Territorial Solid Waste Management Officials (ASTSWMO), Chair of the Board of Registration of Hazardous Waste Site Cleanup Professionals (LSP Board), and as the Southeast Regional Office’s Deputy Regional Director for BWSC. Liz Callahan will be working to support this leadership transition and ongoing MCP amendment implementation efforts through the end of March. 

On Friday, March 1, 2024, MassDEP’s Bureau of Waste Site Cleanup (BWSC) shared several important updates to the BWSC program and the MCP.

2024 Amendments to the Massachusetts Contingency Plan, effective March 1 2024

Practice Tip of the Month
Many municipalities have areas designated for the protection of groundwater quality to ensure its availability for use as a source of potable water supply (e.g., Aquifer Protection Districts).

In anticipation of March 1, 2024, when the MCP Amendments go into effect, the LSPA’s Regulations Committee has been working on summarizing key changes to the MCP regulations. 

Provided below is a summary of the new regulations on a variety of topics not covered by previous LSPA email blasts. This information was developed and is provided on behalf of the LSPA only; it does not represent MassDEP guidance or other input. 

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:

Dear Waste Site Cleanup Program stakeholder,

The following LSPA compliance tip was introduced at the December 2023 Membership Meeting, which was held remotely on December 12, 2023 via Zoom.  

Compliance Tip of the Month

On November 20, 2023, the LSPA sent a white paper to MassDEP entitled “Recommendations for Risk Management Under the MCP for Trichloroethene Exposures Based on Updated Toxicological Information.” The paper was prepared under the auspices of the LSPA’s Technical Practices Committee by Jay Peters of Haley & Aldrich, Inc. and Marie Rudiman of EnviroRisk Solutions, LLC. 

Based on evaluation of the updated scientific evidence referenced in this paper, the LSPA concurs with the findings of EPA studies and others that the association of TCE exposure with congenital heart defects (CHDs) is not scientifically supported. The LSPA proposes that MassDEP seriously reconsider and reevaluate the weight of evidence for TCE-induced CHDs and revise its risk management framework for TCE to be based on the chronic immunological endpoint, rather than the developmental effects endpoint. The paper notes that this would have the following implications for the regulation of TCE in Massachusetts:

Compliance Tip of the Month

The LSPA celebrated its 30^th anniversary in style on October 26^th at beautiful and historic Mechanics Hall in Worcester. Our last annual dinner was in 2019 so this gathering was a reunion of sorts. 30 years and over 300 LSPA members and friends were there. 

It was a great night: 16 LSPA Past Presidents in attendance, an official citation from the Massachusetts State Senate, recognition of Immediate Past President Dave Leone, a Lifetime Achievement Award for Paul Locke, and a viewing of the LSPA’s short video Suspending Disbelief.

The LSPA received notice on October 16, 2023 from MassDEP’s Bureau of Waste Site Cleanup that the updated Compendium of Analytical Methods (CAM) protocols for Trace Metals, WSC-CAM-III A (6010D) and WSC-CAM-III D (6020B), have been posted to MassDEP's website. Also posted are summaries of the significant changes made to the respective existing protocols with these updates.

The effective date for these updated protocols is January 15, 2024. On and after January 15, 2024, any laboratory that is certifying compliance with MassDEP’s CAM protocols for these methods must be complying with these updated protocols.
