What You'll Learn

The Minnesota Pollution Control Agency's (MPCA) focus on minority communities
The Minnesota Pollution Control Agency (MPCA) has a broad mandate to regulate soil, water, and air pollution levels in the state of Minnesota. The MPCA is committed to ensuring that all Minnesotans have access to healthy air, sustainable land, clean water, and a good climate. This includes a focus on preventing and reducing pollution and leading efforts to protect the state from the impacts of climate change.
In recent years, the MPCA has shifted its focus to address environmental issues that specifically concern minority communities in Minnesota. This shift began in 2018 when the MPCA adopted a policy to include an "equity impact" review in each regulation, assessing how the regulation would impact minority communities. The MPCA also began engaging in public meetings and digital outreach efforts to craft policies based on the specific concerns of minority communities through "targeted engagement" initiatives. These race-focused policies also require the MPCA to increase hiring from minority communities as part of its broader "diversity engagement" strategy.
The MPCA's focus on minority communities is part of its commitment to addressing statewide inequities in pollution exposure. The agency works with communities that are disproportionately impacted by pollution and collaborates with programs intended to protect against it. This includes implementing regulatory programs related to the ambient environment and waste management, such as groundwater, surface water, air quality, hazardous waste, and wastewater treatment.
Additionally, the MPCA has been at the centre of controversies surrounding tailpipe emission regulations. In 2020, Governor Tim Walz faced opposition from Republican legislators when he decided to shift the MPCA's tailpipe emission regulations from federal standards to the more restrictive California standards. This decision aimed to reduce greenhouse gas emissions beyond federally mandated levels, but critics argued that it would impact the affordability of internal combustion vehicles. Despite the controversy, the MPCA adopted the California Air Resources Board tailpipe emissions regulations in 2021, setting higher automobile emissions standards than those mandated by the federal Environmental Protection Agency.

The MPCA's work with the US Environmental Protection Agency (EPA)
The Minnesota Pollution Control Agency (MPCA) was established in 1967 to protect Minnesota's air, water, and land. The MPCA works with the US Environmental Protection Agency (EPA) to achieve its goals.
The MPCA's work with the EPA is guided by the Environmental Performance Partnership Agreement (EPPA), established in 2016, which outlines the roles and responsibilities of each agency. The MPCA also collaborates with EPA Region 5, which includes Illinois, Indiana, Michigan, Minnesota, Ohio, Wisconsin, and 35 Tribal Nations. This collaboration aims to protect Minnesota's environment and improve flexibility, accountability, and environmental outcomes.
The MPCA implements federal National Ambient Air Quality Standards (NAAQS) at the direction of the EPA. For example, in 2020, the MPCA adopted more stringent tailpipe emission regulations, aligning with California standards rather than federal ones. This decision was made by Governor Tim Walz, who wanted to reduce greenhouse gas emissions beyond federally mandated levels. The MPCA's work with the EPA also extends to addressing water pollution. The MPCA's Watershed division identifies strategies to assist communities in tackling water pollution and protecting healthy waters.
In addition to its work with the EPA, the MPCA collaborates with various stakeholders, including farmers, regulated parties, businesses, governments, organizations, and Tribal Nations, to develop innovative and community-centered approaches that protect natural resources, enhance human health, and promote economic growth. The MPCA also addresses statewide inequities in pollution exposure, ensuring that minority and low-income communities have a healthy environment and fair treatment in the development and enforcement of environmental laws and policies.
Overall, the MPCA's collaboration with the EPA and other partners is essential to achieving its goals of protecting and restoring Minnesota's environment, reducing pollution, and addressing the impacts of climate change.
