EPA releases proposed 2026 NPDES Multi-Sector General Permit (MSGP) fact sheet describing quarterly 'report-only' PFAS indicator monitoring

EPA published a fact sheet for the proposed 2026 NPDES Multi-Sector General Permit (MSGP) describing 'report-only' indicator analytical monitoring for PFAS on a quarterly basis (as described in the fact sheet). This signals potential new monitoring and reporting expectations for MSGP-covered industrial sectors if finalized; environmental compliance teams should review whether their facilities would be covered and plan for sampling, lab capacity, and data management impacts pending final permit issuance.
