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:

The LSPA received the following email from MassDEP's Bureau of Waste Site Cleanup on Friday. 

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:

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 the topic of Active Exposure Pathway Mitigation Measures (AEPMMS).

The LSPA was pleased to have Acting Assistant Bureau of Waste Site Cleanup (BWSC) Commissioner Elizabeth Callahan and Acting Director of BWSC’s Policy and Program Development Division Ken Marra speak at our September 21, 2023 meeting at the Newton Marriott. 

This event, always very popular, was attended by nearly 200 guests this year – we expect because of the highly-anticipated, recent promulgation of the 2024 MCP Amendments.

MassDEP leadership has recently shared that they expect the next set of Amendments to the Massachusetts Contingency Plan (MCP), proposed in 2019, to be promulgated soon. In an effort to refresh our collective memories, the LSPA Regulations Committee has prepared this brief, high-level summary of eight key aspects of the proposed MCP regulations. The summary provided below is based on the draft revisions provided in 2019. The LSPA has not seen a more recent draft. The actual contents of the forthcoming MCP revisions are not known.

Hot Spot and MGP Waste Definitions 
The 2019 proposed amendments include the addition of Manufactured Gas Plant (MGP) Waste as a defined term. Additionally, the amendments propose modifying the definition of a hot spot to include areas of waste disposal including MGP waste. These proposed changes effectively create a new class of oil and hazardous material (OHM), with concomitant requirements for sampling and risk assessment.

MassDEP announced that the application for the FY2024-25 Technical Assistance Grant (TAG) is now available. This grant opportunity provides $200,000 in funding, with up to $20,000 per community or municipal applicant-group selected for an award, to enhance public involvement and promote better understanding of the cleanup of contaminated sites in their communities. 

The application deadline is Friday, October 13, 2023.

The following LSPA practice tip was introduced at the June 2023 Membership Meeting, which was held in-person at the Westborough Doubletree hotel on June 20, 2023.  

Per 310 CMR 40.0006, Historic Fill cannot contain contaminants that are present as a result of on-site activities. If contaminants at a disposal site could potentially have originated from known historical operations or activities at the site, an LSP needs to first determine that contaminants are not from on-site activities before the contaminants can be attributed to Historic Fill.

When completing an AUL package, be sure to check Appendix D of the AUL Guidance to confirm that you have the right documentation for signature authority. This varies by the type of legal entity (corporation, trust, LLC, Limited Partnership, condominium or Limited Liability Partnership) submitting the AUL, with additional requirements for registered land. 310 CMR 40.1074(2)(c).

Practice Tip of the Month: 
Administrative issues with Activity and Use Limitations (AULs) commonly result in the issuance of Notices of Noncompliance. One helpful tool for reviewing an AUL and its exhibits and assessing whether all requirements for submitting an AUL have been met, is the AUL Compliance Assistance Checklist available in Appendix I of MassDEP’s 2014 Draft Guidance on Implementing AULs.

This notification is required at least three days prior to the commencement of such field work or, if the level of protection is upgraded to Level C or above during the course of the work, as soon as practicable.

The LSPA has developed a Climate Change MCP Toolkit to assist practitioners as they consider the potential effects of climate change on site assessment and response actions. This is anticipated to be required by the pending amendments to the MCP.  The toolkit includes a flowchart, checklist, two case studies, glossary, and list of resources.
