Air Quality Construction Permits
Who Needs a Construction Permit
Any person wishing to construct an air contaminant source or to modify an existing air contaminant source, is required to obtain a construction permit from the Pollution Control Section of the Memphis Shelby County Health Department. Examples of air contaminant sources include:
- Fuel-burning equipment such as boilers, gas- or oil-fired heaters, and coal-fired steam plants
- Incinerators for medical and municipal waste
- Process emission sources such as printing presses, asphalt plants,and coating processes
Farming equipment, mobile sources, and other exempted air contaminant sources are not required to obtain a construction permit.
Air Contaminant Sources
For construction permitting purposes, air contaminant sources typically are classified as major or minor sources depending on their potential to emit pollutants. Major sources generally are:
- Sources that are subject to New Source Performance Standards (NSPS) and have potential total facility emissions greater than 100 tons per year (tpy)
- Sources with potential total facility emissions greater than 250 tpy or more of the following criteria pollutants: carbon monoxide, particulate matter, nitrogen dioxide, sulfur dioxide, lead, and ozone
Minor sources are sources of air contaminants that are not major sources and are not exempt from construction permit requirements. Examples include concrete batch plants, medical waste incinerators, and small surface coating and printing operations.
