Rules & Planning

The Air Quality Bureau develops standards and regulations to protect human health and the natural environment and promote compliance with environmental protection requirements through cooperative work with Iowa citizens, interest groups, industry, and communities.

A major component of this process is the development of rules. The rule making staff develops air quality rules consistent with statutory authority that are protective of Iowan’s interest in having clean air to breathe. They also develop implementation plans to ensure that the National Ambient Air Quality Standards are met.
