LSPA Seeks Your Comments on US EPA’s Proposed PFAS Drinking Water MCL

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.

We also suggest that you submit your comments to EPA directly. Click here for more details. 

EPA held two informational webinars about the proposed PFAS NDPWR in March. The webinar recordings and presentation materials are available here.

EPA will hold a public hearing on May 4, 2023, for members of the public to provide verbal comments to EPA on the rule proposal. Registration is required to attend and the last day to register to speak at the hearing is April 28, 2023. For questions related to the public hearing, contact [email protected]

This EPA webpage provides a summary of the proposed rule, along with links to supporting materials, technical materials, and background information.
