Air Quality Law

The Air Quality Law

• Establishes control and prohibition of indoor air pollution;
• Authorizes DEP to protect ambient (outdoor) air quality and indoor air quality in the County. It prohibits air pollution from crossing property lines or leaseholds;
• States that indoor air pollutants include dust, odor, smoke, gas, radon, asbestos, and biological substances like viruses, bacteria, fungi, and molds; and
• Establishes that a person must not allow the emission of indoor air pollution beyond the person's property line.

• witness a violation; or
• receive complaints from at least two individuals who have personal knowledge of the indoor air pollution.
