What We're Doing - Air

The department works in many ways to protect, improve and maintain Missouri’s air quality as directed by the Missouri Air Conservation Law and the federal Clean Air Act. We issue permits, inspect sources of air pollution, evaluate locations for air monitoring equipment and analyze data collected from these monitors. The department provides financial and compliance assistance and, when necessary, enforcement action to address violations of air regulations. We find ways to reduce emissions across the state and develop state plans to meet federal standards. Learn more about what the department is doing to reduce air pollution and protect the health of Missouri's citizens and its visitors.
