Small Business Air Permitting Issues

If your facility has any process which emits any gases or materials (other than pure water vapor) to the atmosphere, an air quality permit may be required. The main pollutants of concern are referred to as "criteria pollutants," and include:

  • PM10 (particulate matter less than 10 microns in diameter)
  • Ozone (regulated in part by controlling emissions of volatile organic compounds or VOCs)
  • Sulfur Dioxide (SO2)
  • Oxides of Nitrogen (NOx)
  • Carbon Monoxide (CO)
  • Lead (Pb)

Hazardous Air Pollutants (HAPs) and Toxic Air Pollutants (TAPs) must also be considered. Many are commonly used as solvents, coating ingredients or may be emitted as byproducts of industrial processes.

Permit Issues by the Division of Air Quality

  • Permit to construct, modify or relocate minor stationary sources of air pollution.
  • Permit to construct, modify or relocate major stationary sources of air pollution.
  • Permit for pre-construction review, determination of emission offsets for proposed new or modified stationary sources of air pollution, and emission trading for intra-source pollutants.
  • Air pollution control permit for hazardous waste treatment, storage and disposal facilities.
  • Operating permit.
  • General air quality permits for six specific types of sources.
  • Permits by standard industrial classification codes.
