The MPCA works with the federal EPA and local governments to ensure that Minnesota’s air is healthy for all to breathe. One of the primary ways that we do this is through regulating pollution sources. The Clean Air Act gives the EPA authority to regulate air pollution by setting standards. The EPA sets standards both for how much of certain pollutants can be in the air, and also for how much air pollution specific types of sources can emit.
The Clean Air Act then places much of the responsibility of preventing and controlling air pollution on the states. States must pass laws and write rules that will ensure that the state’s air quality meets federal standards. States issue air emission permits to ensure that sources of air pollution meet all federal and state regulations. States then inspect facilities and enforce these regulations. They also receive emissions data from facilities and monitor air quality.
