Ongoing Updates on MCP-Related Information
Watch this space on the MassDEP website for updates and “related information” on the 2024 MCP. At this time, updates include:

On May 30, 2023, the LSPA submitted comments to USEPA via the Federal eRulemaking Portal regarding the proposed National Primary Drinking Water Regulation (NPDWR) for PFAS, under Docket ID: EPA-HQ-OW-2022-0114. Read the LSPA comment letter here. This was the first time in over a decade that the LSPA has commented on a proposed USEPA rule.

This USEPA webpage provides a summary of the proposed rule, along with links to supporting materials, technical materials, and background information. A small group of LSPA members including toxicologists, public health risk assessors, and LSPs with decades of experience reviewed and provided comments on this rule. The LSPA comments were organized according to the topics outlined in the slides from this USEPA presentation, Proposed PFAS National Primary Drinking Water Regulation (epa.gov).
