The notice of Request for Comments on this rulemaking was published in the State Register (July 24, 2023); the MPCA specifically requested comments on the concepts for the rules.


Currently, Minnesota facilities with air permits voluntarily report emissions of hazardous air pollutants (HAPs, also known as air toxics) every three years to the MPCA. The MPCA is planning rule amendments to require annual reporting on air toxics emissions from permitted facilities (except those with Option B registration permits) located in Anoka, Carver, Dakota, Hennepin, Ramsey, Scott, or Washington counties. The MPCA has three main goals for these rule amendments as directed by Minnesota Session Law – 2023:

  1. Establish the requirements for air toxics emissions reporting for permitted facilities on an annual basis.
  2. Identify the air toxics to be reported.
  3. Amend permit and reporting processes to align with annual air toxics emissions reporting.

July 2020

The MPCA held a webinar about the current Minnesota air toxics reporting structure and what a potential mandatory reporting requirement could include. Through the webinar and subsequent comment period, MPCA heard from more than 60 Minnesotans and organizations. The MPCA will consider this input received in this rulemaking.
