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).

On March 14, 2023, EPA announced the proposed National Primary Drinking Water Regulation (NPDWR) for six PFAS including PFOA, PFOS, PFNA, HFPO-DA (commonly known as GenX Chemicals), PFHxS, and PFBS. EPA anticipates finalizing the regulation by the end of 2023. For more details click here.

The LSPA will review the proposed regulation and provide comments to EPA during the public comment period, which ends on May 30, 2023. If you have comments you would like the LSPA to consider, please send them to [email protected] by April 28, 2023.
