The operating permit program is a national air permitting requirement under Title V of the federal Clean Air Act Amendments of 1990 and is administered by each state. In Michigan, these permits are known as Renewable Operating Permits (ROPs). This page is designed to help initial applicants and those renewing applications navigate the obligations of the permitting program and provide resources to guide facilities through the process. For more information, see the ROP Program Overview.
The Air Quality Division shares information about facilities regulated by state and federal air quality regulations in Michigan through MiEnviro Portal Site Explorer.
This information includes but is not limited to, Permits to Install (PTI), Renewable Operating Permits (ROP), inspection reports, stack test reports, and enforcement documents. Lists of historical information, pre-December 10, 2024 is still available.
A source that becomes subject to Title V must submit an initial application.
Once a source has an ROP, it must renew the permit every five years.
Sometimes a source needs to make changes to its ROP after a permit is issued.
ROPs are required to undergo public comment.
Some ROPs are required to have CAM plans as part of them.
ROPs are required to submit compliance-specific records.
Currently, the Templates by Rule are identical for initial and renewal applications. That may change in the future.
