Air Quality Public Notice

This page contains links to actions EGLE's Air Quality Division is currently looking for public input on.  Comments EGLE can consider include technical mistakes, grammar and spelling mistakes, other rules that should be considered, and other items which should be included or removed.  Some issues EGLE cannot consider include popularity of the action, emission sources that are not part of the action, indoor air pollution, traffic, hours of operation, noises and lighting, and zoning issues.

The law requires EGLE to gather public input on some actions and use it during the decision-making process. Public comments are a very important part of making sure the decisions have been thoroughly reviewed and all aspects considered. Based on comments received during the public comment period, EGLE may complete the action as proposed, deny the action, or revise the action.

Permits to Install (PTIs)

The air permitting program requires industry to ensure new or air emission sources meet the regulations when they are built or when certain changes are requested. An air permit is required before the installation, or the changes can be made. These preconstruction air permits are commonly referred to as a "Permit to Install" (PTI). 

PTI applications may be put out for public comment for a variety of reasons, such as the level of pollutants being requested or because the application is of public interest.

Renewable Operating Permits (ROPs)

Larger sources of air pollution are also required to have a major source permit, commonly known as a "Title V permit" or "Renewable Operating Permit" (ROP). This type of air permitting must be opened for public input. This section contains information about permits open for 30-day public comment, in 45-day comment for USEPA, and those that have had a final decision.

Air Quality Rules and the State Implementation Plan (SIP)

Michigan's Air Pollution Control Rules are made up of multiple "parts" each covering its own subject matter and/or pollutants, which often need updating. It is also possible the AQD needs to create new rules to address air quality issues in the state. These are included in Michigan's State Implementation Plan (SIP). Some portions of the SIP are occasionally open to public input.
