Air Quality Management
October 2007
Air pollution comes from many different sources such as factories, power plants, dry cleaners,
cars, buses, trucks, and even windblown dust and wildfires. Air pollution can threaten the health
of human beings, trees, lakes, crops, and animals, as well as damage the ozone layer and
buildings. To help determine if air quality regulations apply to your facility, consider the following
questions:
1. Does the facility have a spray booth? Welding or sandblasting units? A parts
washer?
2. Are these units operated inside a closed building/room?
3. Do vehicles meet the state or local emissions inspection requirements?
4. Is the facility in a non-attainment area? (Refer to the “Managing Air Emissions” Fact
Sheet for more information on non-attainment areas.)
5. Does the facility have air conditioning units or vehicles with air conditioning?
If you answered yes to any of the above questions, the Air Quality Management regulations at
the state and/or federal level (for example, the Clean Air Act, Title V amendment) may apply to
you. Review this section on Air Quality Management for more guidance.
