Air Quality

Complying with environmental regulations can often be burdensome for Pennsylvania small businesses especially when it comes to issues related to air quality.  Complex regulatory language, long permitting forms and applications, and the need to quantify air emissions from stationary sources, equipment, or operations often confuse small businesses. 

While small business typically do not emit as much air pollution as a large business normally does, small businesses may still be regulated and subject to air quality permitting or other regulations. 

What are common air pollutants and how are they regulated?

The most common air pollutants are carbon monoxide (CO), nitrogen oxides (NOx), sulfur oxides (SOx), particulate matter (PM10), volatile organic compounds (VOCs), and hazardous air pollutants (HAPs). Operations that emit one or more of these pollutants may be subject to permitting regulations. This depends not only on actual pollution emitted, but also on the potential to emit.

Does the size of my business matter?

Air permitting regulations are based on the amount of air pollutants that a business can or does emit, not on business size.

How do I determine the total emissions from my facility?

Look at all sources at your facility that emit pollutants. A “source” is any piece of equipment with potential to emit pollutants. Each individual source is subject to regulations.

Do all air emission sources require permits?

No! The Pennsylvania Department of Environmental Protection (DEP) has exempted some types of air pollutant sources from permit requirements because their emissions are of minor significance. Businesses that meet exemption requirements do not need to apply for an air quality permit.

Who is subject to Air Regulations?

The resources below will help you learn about local, state and federal air pollution control regulations and how they apply to your business.

In Pennsylvania, Allegheny and Philadelphia counties have air pollution control regulations separate from the rest of the state.  If your business is in one of those counties, refer to the links below.  Federal air pollution regulations apply to all facilities in the U.S.
