EPA publishes primacy/implementation timeline and extension request materials for the PFAS NPDWR

EPA posted primacy extension request documents and related implementation materials for the PFAS National Primary Drinking Water Regulation (NPDWR). The materials summarize key primacy/implementation milestones for states (including primacy revision package due dates and extension pathways) and provide templates/supporting documents to request primacy extensions. Compliance teams at water utilities and state primacy agencies should use these materials to plan regulatory adoption schedules, monitoring program build-out, and capital planning aligned to the NPDWR implementation timeline.
