Air Quality Division Delegations

Contact: See Below
Agency: Environment, Great Lakes, and Energy

The United States Environmental Protection Agency (USEPA) has delegated certain federal standards to the Air Quality Division (AQD). For those standards, the AQD is the agency of receipt for notifications, reports, and other compliance related requirements. The USEPA does not delegate certain responsibilities to states, such as major testing changes.

Area Source MACT Delegations

Michigan has received full delegation of certain MACT standards. Sources that are subject to these standards must report information to the appropriate AQD District Office and, if indicated in the standard, to the USEPA. Information on required source reporting can be found on the AQD Renewable Operating Permit (ROP) web page. Sources that are subject to some of these standards are subject to an annual facility charge as described in the AQD Fee Calculation web page.

Below is a chart of the current area source MACT standards delegated to Michigan including information on fee applicability.
