The MPCA strives to ensure all people in Minnesota have clean air, regardless of where they live or work.
Understanding small-scale differences in air pollution is important for minimizing exposure to harmful air pollutants, particularly for vulnerable communities.
The MPCA's air monitors continually measure pollutants. With this data, the agency can track pollution trends over time and show if outdoor air meets air quality standards and health benchmarks.
Minnesota’s air currently meets all federal air quality standards. However, even levels of air pollution below the standards can affect people’s health, including levels currently found in parts of Minnesota.
Air quality dispersion modeling uses a computer model to estimate air pollution concentrations from regulated facilities and other sources of pollution.
Air sensors are instruments that measure air quality conditions in near real time.
Minnesota is a national leader in ensuring healthy air quality. The Clean Air Act requires states to take significant responsibility for preventing and controlling air pollution. States must pass…
The Minnesota State Implementation Plan (SIP) is focused on the six criteria air pollutants regulated by national ambient air quality standards (NAAQS): ground-level ozone, fine particles, lead, nitrogen dioxide, carbon monoxide, and sulfur dioxide.
Air pollution levels in Minnesota have steadily decreased over the past few decades and currently meet federal standards. But even levels that meet or are below these standards can affect people’s…
Learn what steps you can take to reduce the pollution from small neighborhood sources.

The AQI was developed to provide a simple, uniform way to report daily air quality conditions.
MPCA’s community air monitoring pilot grant program will provide $4.85 million to build more networks of community air sensors in the Twin Cities metro area.
Minnesota continues to reduce industrial and transportation air pollutants that have the highest potential health risks. Investment in clean air for all Minnesotans is a top priority for the MPCA and Governor Walz.
Are pets affected by poor air quality? Will wearing a mask help when I’m outside? What is particulate pollution? We’ve got the answers.
The MPCA enforces federal and state requirements for air quality permitting.
An air emission permit is a legal document that describes how a facility must operate to meet state and federal air regulations, and to minimize the impact of air emissions on people and the…
