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 new regulations.

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). This information was developed and is provided on behalf of the LSPA only; it does not represent MassDEP guidance or other input. MassDEP training is expected to take place in January 2024.

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.

The following LSPA compliance tip was introduced at the May 2023 Membership Meeting, which was held virtually via Zoom on May 18, 2023.  

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).

The following LSPA practice tip was introduced at the February 2023 Membership Meeting, which was held virtually on February 15,  2023.  

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.

The following LSPA practice tip was presented at the January 2023 Membership Meeting, which was held virtually through the Zoom webinar platform, on January 26, 2023.  

Compliance Tip of the Month: 
Pursuant to 310 CMR 40.1403(3)(a), notification to the Chief Municipal Officer and Board of Health of a community in which a Disposal Site is located is required when respirators or other protective clothing (Level A, B, or C Personal Protective Equipment) is used at a Disposal Site. 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 following LSPA practice tip was presented at the December 2022 Membership Meeting, which was held virtually through the Zoom webinar platform, on December 14, 2022.  

Compliance Tip of the Month: 
Consistent with 310 CMR 40.1003(7), if all other MCP closure requirements are met, a site with NAPL may be closed with a Permanent Solution With Conditions (PSWC) following complete evaluation of the nature and extent of the NAPL, including demonstration of the following consistent with Policy #WSC-16-450:

The following LSPA practice tip was presented at the November 2022 Membership Meeting, which was held virtually through the Zoom webinar platform, on November 15, 2022.  

Practice Tip of the Month: 
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.

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 following LSPA practice tip was presented at the October 2022 Membership Meeting, which was held virtually through the Zoom webinar platform, on October 27, 2022.  

Practice Tip of the Month: 
Did you know MassDEP's position is that discarded carbon canisters, as a generated waste, are a sludge and subject to 310 CMR 30.302: Determination of Whether a Waste is Hazardous? Accordingly, per policy HW94‐007, a spent carbon canister that contains hazardous waste constituents from a listed hazardous waste source must be managed as a hazardous waste, regardless of whether the carbon canisters were used to treat groundwater or vapors from groundwater or soils.

The following LSPA compliance tip was presented at the April 2022 Membership Meeting, which was held virtually through the Zoom webinar platform, on April 14, 2022.  

Compliance Tip of the Month: 
Any time environmental samples are taken at a listed disposal site on behalf of someone other than the owner of the property, the person(s) conducting the response action shall provide the owner of the property with a written notice using BWSC-123 prior to the sampling, or no more than seven days after the sampling if it was conducted as part of an IRA to address a 2-hour notification. 

The following LSPA compliance tip was presented at the December 2021 Membership Meeting, which was held virtually through the Zoom webinar platform, on December 14, 2021.  

Compliance Tip:
When using a Method 2 or Method 3 risk characterization to establish a condition of NSR, you must consider reasonably foreseeable, as well as current, site activities and uses. In particular, future vapor intrusion exposures could result from changes in building use or altered building conditions. Potentially problematic activities and uses can be eliminated from consideration in the risk characterization through an appropriate AUL, per 310 CMR 40.0923(3)(b).

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).
