Air Quality, Inventory and Reporting (1460DP) - Natural Resources, Department of

This bill updates Iowa's air quality reporting requirements for the Department of Natural Resources (DNR). It changes the annual greenhouse gas emissions report deadline to align with the U.S. EPA's schedule, requiring the DNR to report emissions from the two prior calendar years instead of one. The bill also removes redundant state-level requirements for a voluntary greenhouse gas registry and operator certification, as these are now covered by federal rules. These changes primarily affect the DNR and regulated businesses that report emissions under the Clean Air Act.
