A bill for an act relating to duties of the department of natural resources related to air quality including reporting requirements, certifications, data gathering, and rules references.

This bill updates Iowa's Department of Natural Resources (DNR) air quality reporting requirements. It changes the annual greenhouse gas emissions report to cover emissions from two prior calendar years (aligning with EPA's schedule) and allows the EPA's annual inventory to fulfill this state requirement. The bill also removes outdated references to administrative rules and repeals provisions requiring the DNR to create a voluntary greenhouse gas registry and certify solid waste incinerator operators. These changes primarily affect the DNR's reporting duties and regulated facilities subject to emission fees.
