Rules and 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.

Rule Making - Recently Completed

The Environmental Protection Commission (Commission) approved the final air quality rulemaking known as the Air Electronic Submittal Rulemaking on March 15, 2022. The Commission approved the final rules after a public comment period and a public hearing. One written comment in favor of the rule changes was submitted. Iowa DNR made a minor change to the final rule from the published Notice of Intended Action to correct an outdated address.

Summary of Rule Changes

This new rule will require electronic submission of all air emissions reporting, air permit applications, and other related air quality documents, starting January 1, 2023.

Under the final rule changes, minor sources of air emissions will be required to file emissions data using the State and Local Emissions Inventory System (SLEIS). Additionally, both major and minor sources of air emissions will be required to use the Iowa Environmental Applications System for Air (Iowa EASY Air) for all air construction and Title V operating permit applications.
