MODERATE

The bill was expanded from a single sponsor to a bipartisan group of eight senators and advanced through the legislative process to become law. The core policy change shifts the approach to PFAS regulation from immediately setting new limits for all substances to modifying the existing limit for PFOA/PFOS while establishing a new limit for GenX, and deferring the decision on cumulative exposure rules until May 2028.

Scope change

The bill's scope was broadened by adding multiple sponsors and advancing its status to a passed Senate bill ready for the Assembly.

REQUIREMENT

Changed the requirement for PFOS and PFOA from establishing a new limit to modifying the existing maximum contaminant level to no higher than 4 parts per trillion.

Added a specific requirement to establish a maximum contaminant level no higher than 10 parts per trillion for GenX (HFPO-DA).

TIMELINE

Moved the deadline for determining additional requirements to address cumulative exposure from an immediate mandate to a report due by May 1, 2028.

TECHNICAL

Added a new section (12-a.c) clarifying that public water systems must comply with the maximum contaminant levels by May 1, 2029.

SCOPE

Added GenX (HFPO-DA) to the list of specific substances being regulated.
