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.

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.

Through this Minnesota climate smart food systems (CSFS) grant, the MPCA is soliciting proposals to distribute $7.2 million in grant funding for technical assistance and planning services to food and beverage manufacturers and organic waste processors across Minnesota.

Through this Minnesota climate smart food systems (CSFS) grant, the MPCA is accepting applications for grants to reduce refrigerant emissions in retail food refrigeration, cold storage, and food assistance programs in Minnesota. Refrigeration projects must include replacing existing equipment to use a natural refrigerant such as carbon dioxide (R-744), ammonia (R-717), and propane (R-290).

Through this Minnesota climate smart food systems (CSFS) grant, the MPCA sought project proposals to partially fund new, cleaner versions of fossil fuel on-road and off-road equipment and vehicles in Minnesota.

MPCA completed 100 enforcement cases for water quality, air quality, waste, stormwater, and wastewater violations in the first half of 2024

Approximately $4.5 million was available to support prevention of wasted food and food rescue projects across the state.

In Minnesota, handlers of oil and hazardous substances are required to prepare for potential spills and take steps to prevent them.

MPCA had approximately $1 million for projects that increase the efficiency or effectiveness of waste reduction, reuse, recycling, or composting programs in Greater Minnesota.
