The MPCA studies Minnesota's solid waste composition and processes to inform policy recommendations, legislative proposals, education and outreach messages, and waste reduction efforts.
Air quality dispersion modeling uses a computer model to estimate air pollution concentrations from regulated facilities and other sources of pollution.
In early 2024, Minnesota became the first U.S. state to establish a product stewardship program for boat wrap, which must provide free collection, transportation, reuse, recycling, and disposal.
MPCA awards $2.4 million to eight organizations for projects focused on sustainable building and materials management strategies that reduce waste and increase deconstruction, salvage, and reuse in Minnesota.
In 2023, Minnesota saw more air quality alerts covering more days than ever before. Smoke from Canadian wildfires throughout the summer caused many of the alerts, though climate change is playing a growing role in Minnesota's air quality.
The MPCA investigates sites where hazardous substances have been or could be released to identify risks and appropriate remediation plans.
When temperatures climb and the summer sun beats down, conditions are ripe for Minnesota lakes to produce harmful algae blooms, some of which can be harmful to pets and humans.
The MPCA completed 68 enforcement cases for water quality, air quality, hazardous waste, stormwater, and wastewater violations in the first half of 2025.
In Minnesota, about 18,000 regulated underground storage tanks (UST) are in use. State rules specify requirements for underground storage tanks (UST) that store petroleum or hazardous substances, and any piping or other structures that are part of the tank systems.
Facilities that produce air emissions can benefit by proposing limits on their own operations to avoid certain types of regulatory requirements. You might accept limits to stay under emission…
All facilities with air permits must submit an annual emissions inventory report to the MPCA that tracks actual emissions of major pollutants at that facility.
The MPCA 401 certification fills a unique niche in protecting water quality by applying state water quality standards to projects.
The MPCA closed 118 enforcement cases for water quality, air quality, waste, stormwater, and wastewater violations in the second half of 2023.
The Mississippi River - Lake Pepin Watershed includes 205,747 acres that drain several small, coldwater streams in bedrock-dominated bluff country.
A water quality variance is a temporary change in a state's water quality standard for a specific pollutant and its relevant criteria, allowing deviation from meeting a water quality-based effluent limit for a particular discharger.
