Minnesota PFAS Initial Reporting Deadline Extension

Minnesota PFAS initial reports now due Sept. 15, 2026

On April 15, 2026, the Minnesota Pollution Control Agency (MPCA) officially delayed the initial reporting deadline for the state’s PFAS reporting requirements to September 15, 2026.

Manufacturers must now submit their data to the Minnesota PFAS Reporting Information System for Manufacturers (PRISM) by that date. Manufacturers who are unable to meet the September 15 deadline may apply for a single 90-day extension, which would move their reporting deadline to December 14, 2026. The previous reporting deadline was July 1, 2026.

Extension and waiver request forms are now available on the MPCA’s PFAS in product reporting webpage and must be postmarked by August 16, 2026.

These changes have effectively given affected manufacturers over three and a half years to prepare and submit reports since reporting requirements were passed. According to the MPCA, the deadline extension is intended to support more complete and higher‑quality PFAS data submissions to better inform the state’s PFAS pollution prevention efforts.

Why MPCA extended the reporting deadline

The MPCA reports that over 500 companies have registered in the PRISM system, with 18 manufacturers already submitting PFAS reports ahead of the deadline. Submitted reports are publicly available through PRISM, with the exception of trade secret data.

At the same time, MPCA has acknowledged feedback from manufacturers regarding challenges associated with both using the PRISM platform and collecting PFAS information across complex supply chains. These challenges are particularly significant for manufacturers of multi‑component products.

In response, MPCA is rolling out additional educational tools and expanded technical assistance, including downloadable reporting guides, new how‑to videos, and individual virtual technical support sessions. Manufacturers experiencing technical issues within PRISM can contact prism@theIC2.org, while questions related to reporting obligations can be directed to pfasreporting.mpca@state.mn.us.

What this means for pending Minnesota PFAS legislation

While the MPCA has administratively extended the reporting deadline, separate legislative proposals remain under consideration that could further modify PFAS reporting requirements.

House File HF 4257, introduced on March 12, 2026, would delay the Minnesota PFAS reporting deadline to July 1, 2027 if enacted. The bill also proposes adjustments to the Currently Unavoidable Use (CUU) process and potential exemptions for broad product categories, including automobiles, aligning Minnesota more closely with approaches taken in other states such as New Mexico. A companion Senate bill, SF 5092, contains identical language.

At this time, HF 4257 and SF 5092 remain proposals only. Neither bill has passed the Minnesota Legislature or been signed into law. As a result, manufacturers should continue planning around the current MPCA deadline of September 15, 2026, while closely monitoring legislative developments.

GreenSoft will continue tracking both regulatory and legislative activity and will publish updates on our  blog if and when any statutory changes are enacted.

How GreenSoft helps manufacturers navigate Minnesota PFAS reporting

As the MPCA has acknowledged, one of the biggest challenges that manufacturers face in meeting Minnesota’s PFAS reporting requirements is collecting accurate PFAS data across complex supply chains and translating that information into PRISM‑ready submissions. GreenSoft Technology supports manufacturers at every stage of that process.

GreenSoft PFAS Data Services can help manufacturers tackle the complexity of PFAS data collection by working directly with suppliers to collect documentation, validating PFAS content disclosures, and helping close data gaps that commonly delay reporting. For manufacturers struggling to obtain complete information from suppliers by the reporting deadline, GreenSoft’s services provide a structured, defensible approach aligned with MPCA guidance for first‑round compliance.

Once PFAS substance data is collected, GreenSoft’s GreenData Manager (GDM) software helps manufacturers move efficiently from data to submission. GDM can generate Minnesota‑specific PFAS reports aligned with PRISM substance lists and required data fields, allowing users to consolidate PFAS information across products and bills of materials. These reports can then be used to efficiently populate the official PRISM Excel template, reducing manual entry, improving consistency, and helping manufacturers identify potential issues, such as missing identifiers or unlisted substances, before submission.
