relative to PFAS facility liability.

HB 1389 establishes strict liability for owners or operators of facilities that release PFAS chemicals into groundwater, triggering cleanup requirements when contamination reaches 500 parts per trillion or higher. It directly affects businesses handling PFAS (like manufacturers or waste facilities) that caused such contamination. The bill mandates compliance with federal cleanup regulations (40 CFR 265.111 and 265.114) for equipment, piping, and building surfaces used with PFAS. This requires facilities to address contamination through closure, decommissioning, or remediation of affected infrastructure.
