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.
Pretreatment by commercial facilities and other non-domestic wastewater sources removes harmful pollutants before the wastewater is discharged to a municipal sewer system. The U.S. EPA has delegated MPCA the authority to approve pretreatment programs at the local level and oversee statewide pretreatment activities.

Partnerships and diversified funding drive the work to restore water quality in impaired streams in the Red Lake River Watershed through science-based interventions.
The MPCA and its many partners collect a wide variety of data on environmental conditions and pollution sources.
Composting organic waste and compostable products creates a valuable product that improves soil fertility, conserves water, and reduces erosion.
MPCA is planning new rules governing how the MPCA determines currently unavoidable uses of per- and polyfluoroalkyl substances (PFAS) in products.
New rules establish a program for the MPCA to collect information about products containing intentionally added PFAS and establish fees to be paid upon submission of required reporting.
Minnesota’s policy is to eliminate or reduce the use, generation, and release of toxic pollutants and hazardous wastes at their source.
When leaves fall on streets, sidewalks, and other hardscapes in urban areas, they wash into the storm drains and end up in lakes and rivers where they feed algae growth. The algae then decomposes and uses up oxygen that fish and native plants need.
Underground storage tank (UST) facilities must designate owners, operators, or employees as Class A, Class B, and Class C operators.
Permit applications must include detailed emissions calculations to help determine which permit type or permit amendment is needed.
Water softeners produce much of the chloride that pollutes Minnesota’s waters. An MPCA grant aims to reduce that pollution with water softener replacement rebate programs.
Minnesota has enacted laws to end avoidable uses of PFAS in Minnesota by 2032.
The Olmsted Soil and Water Conservation District's Soil Health Farm demonstrates how farmers can benefit from practices that also provide resilience to climate change.
