States are responsible for developing a Regional Haze State Implementation Plan (SIP) that addresses regional haze in each Class I area located within the state and in each Class I area located…
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.
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…
Understanding small-scale differences in air pollution is important for minimizing exposure to harmful air pollutants, particularly for vulnerable communities.
To ensure that every person in Minnesota has healthy air to breathe, the MPCA studies, monitors, and regulates air pollutants, primarily in three categories: criteria pollutants, air toxics, and greenhouse gases.
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.
The MPCA strives to ensure all people in Minnesota have clean air, regardless of where they live or work.
Air sensors are instruments that measure air quality conditions in near real time.
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.
As Minnesotans prepare for another summer of outdoor activities, MPCA meteorologists are forecasting a moderately active air quality season.
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…
Our strategic plan has six broad goals that, when taken together, map our work for five years. MPCA’s strategic plan guides the agency’s work from Jan. 1, 2024, to Dec. 31, 2028. These goals are…
When people think of sources of air pollution, they typically think about buildings with big smokestacks like power plants and factories. Only about a quarter of the air pollution in Minnesota comes…
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.
The AQI was developed to provide a simple, uniform way to report daily air quality conditions.
Through this Minnesota climate smart food systems (CSFS) grant, the MPCA is soliciting proposals to distribute $40 million in grant funding to support industrial food and beverage manufacturers and food system organic waste processors across Minnesota through capital expenditure projects that will improve operational efficiency, reduce operating costs, and lessen environmental impacts at facilities.
