Minnesota PFAS Reporting: Deadline Extension and Enhanced Support

At a Glance

• Manufacturers who require additional time may apply for a 90-day extension, moving the final deadline to December 14, 2026. Request forms, along with the associated fees, must be postmarked by August 16, 2026, to be considered.
• The extended deadline to September 15, 2026, enhanced resources from the MPCA, and ongoing improvements to the PFAS Reporting and Information System for Manufacturers (PRISM) system provide additional support; but gathering PFAS data from supply chains and preparing accurate reports will still require significant lead time.

Minnesota's Products Containing PFAS law, also known as Amara's Law, requires manufacturers to report intentionally added per- and polyfluoroalkyl substances (PFAS) in products sold, offered for sale, or distributed within the state. The Minnesota Pollution Control Agency (MPCA) has extended the initial reporting deadline to September 15, 2026, and is introducing new educational resources and enhanced technical support for manufacturers. MPCA is also updating the PFAS Reporting Information System for Manufacturer (PRISM), the reporting system, in response to user feedback, with further improvements scheduled for late April 2026.

Background on Minnesota PFAS Reporting

Amara's Law, Minn. Stat. § 116.943, establishes compliance obligations for businesses selling products with intentionally added PFAS in Minnesota. Manufacturers are required to submit detailed information to the MPCA about products containing PFAS that are sold, offered for sale, or distributed within the state. The PFAS Reporting and Fees Rule, adopted in November 2025, further details the information manufacturers must report, including a description of the product, PFAS chemicals in the product, PFAS concentration, PFAS function, and contact information.

The initial reporting deadline originally was set for January 1, 2026. During the rulemaking process, MPCA extended the deadline to July 1, 2026, to allow manufacturers additional time to collect data, and MPCA time to finalize the reporting system. As detailed below, MPCA is extending the reporting deadline for a second time.

Reporting Deadline Extension

To address manufacturer difficulties in using PRISM and gathering PFAS data, MPCA is extending the initial reporting deadline to September 15, 2026. Manufacturers who require additional time may apply for a 90-day extension, moving the final deadline to December 14, 2026.

To obtain an extension, a manufacturer must explain the circumstances preventing timely submission, describe efforts taken to comply, and provide a plan for submission by the extended deadline. Extension and waiver request forms are now available on the MPCA's Reporting PFAS in Products webpage. In completing these forms, MPCA encourages manufacturers to be concise, stating that a "successful request does not require extensive supporting documentation." MPCA has stated that these forms, along with the associated fees, must be postmarked by August 16, 2026, to be considered. If an extension request is denied, manufacturers must submit a report within 30 days after the notice of denial, or by the established reporting due date, whichever is later.

Educational Resources and Technical Support

Recognizing the complexities of data collection and entry, MPCA is also providing new educational tools and enhanced support for PRISM users. In the spring of 2026, MPCA will release short instructional videos covering common reporting processes, based on current PRISM resources and commonly asked questions. MPCA will also offer virtual "office hours" with staff for technical issues best addressed through live video and screen sharing. Further, MPCA will continue to improve the PRISM interface, with additional updates expected in late April 2026.

Looking Ahead

Businesses subject to Minnesota's PFAS reporting requirements should continue collecting PFAS data to ensure timely compliance. The extended deadlines, enhanced resources, and ongoing improvements to the PRISM system provide additional support; but gathering PFAS data from supply chains and preparing accurate reports will still require significant lead time. By leveraging the updated guides, technical assistance, and new educational tools, companies can reduce compliance risks and position themselves to meet Minnesota's requirements.
