A project to address excess sediment and turbidity in the Mississippi River, from Fort Snelling at St. Paul to upper Lake Pepin at Red Wing, based on a site-specific standard developed by the MPCA and Wisconsin Department of Natural Resources.

Some facilities may have air emissions low enough to qualify as "insignificant," and not be required to have an air permit.

Nitrogen management plans help operators of wastewater treatment facilities understand the inputs of nitrogen to their facilities and evaluate options that can reduce the amount of nitrogen discharged.

MagIron LLC proposes to restart a mining and processing facility near Grand Rapids, which will require new air and industrial wastewater permits from the MPCA.

The effects of contaminants of emerging concern (CECs) on fish, wildlife, and humans are only partly understood. The MPCA has been collecting occurrence data for a diverse set of CECs, but toxicity…

Product stewardship encourages manufacturers, retailers, and consumers to treat products as resources rather than waste, changing how they think about the products they make, buy, and use.

Bagnado, a 25-foot-tall spinning tornado of plastic bags, will return to Eco Experience at the Minnesota State Fair

Edina-based startup, Naware, recently took the $10,000 Green and Sustainable Chemistry Prize, sponsored by the MPCA as part of the MN Cup, for combining two unlikely technologies to replace herbicides in lawncare with a more environmentally friendly alternative.

SSTS inspections determine if the design and installation meet code requirements and whether the system is functioning properly to protect public health and groundwater.

Areas and communities with SSTS concerns have wastewater treatment methods that are not adequate to protect public health or the environment. Hundreds of small communities around the state have inadequate wastewater systems.

Local governments with SSTS programs submit information to the MPCA each year on SSTS permitting and compliance trends for the previous calendar year. The information helps the agency with long-range planning efforts.

Air quality is expected to reach the orange AQI category, which is unhealthy for sensitive groups, in the Twin Cities and central Minnesota

Lake of the Woods is a big lake with a big problem caused by one of nature’s smallest organisms: algae. Scientists from the MPCA and the Science Museum are working together to understand why.

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…
