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 Board of Registration of Hazardous Waste Site Cleanup Professionals (“LSP Board”) has opened a comment period and will hold a public hearing on the proposed amendments to the regulations at 309 CMR 1.00-9.00: Regulations of the Board of Registration of Hazardous Waste Site Cleanup Professionals. The proposed amendments include changes to:

• Continuing education requirements for LSPs and course providers
• Examination procedures
• Definitions, license renewals, and other topics

The proposed amendments, a background document, and public meeting registration link are available on the LSP Board’s website.
