Air Quality Law

 
Chapter 3 of the Montgomery County Code is the Air Quality Control Law. The law authorizes DEP to protect ambient (outdoor) air quality and indoor air quality in the County. It also prohibits air pollution from crossing property lines or leaseholds.

Air pollution is defined in the Air Quality Control Law as the presence in the atmosphere of any substance (or combination of substances) likely to pose a health hazard to humans, plants, or animals or unreasonably interfere with the use and enjoyment of property. Air pollutants include odors, smoke, gas, and dust.
