Air Permitting

Air permitting requirements vary and are site-specific. Depending on the project, air permits may be required from multiple permitting agencies (federal, state, local, or tribal). The type of permit required is based on the source of the air pollution, the quantity of emissions, and the location of the project. Usually, the more emissions emitted from a facility, the more stringent the air permit.


In general, air permits may be required for the construction and operation of new or modified stationary sources of air pollution. Air permits may also be required for the modification or replacement of existing air pollution sources or controls.

The permitting process begins with submitting an application to the appropriate permitting agency. The application must include information on the source of the air pollution, the size and type of equipment, the location of the project, and the proposed air pollution control measures. Atmospheric dispersion modeling and other specialized modeling may also be required to demonstrate compliance with various standards before permits are issued.

Many air permitting programs typically include requirements for public participation, such as public hearings and comment periods. After this process, the permitting agency will issue a permit that includes the emission limits and other conditions that must be met by the project.

The permitting process can be complex and time-consuming. It is important to consult with the appropriate permitting agency early in the project planning process to ensure that all requirements are met.
