Nearly 90% of ozone-forming air pollution in Mecklenburg County comes from mobile sources likes cars, trucks, and construction equipment. There are two reliable indicators of on-road mobile source air pollution:
Non-road mobile sources, like construction equipment, can emit a significant amount of air pollution. To reduce non-road mobile source emissions, MCAQ offers their award-winning
Grants to Replace Aging Diesel Engines (GRADE) program. GRADE provides businesses and organizations funding incentives to replace or repower older diesel-powered vehicles and equipment with newer cleaner-operating equipment.
Stationary sources are generally larger sources of air pollution that are not mobile. MCAQ permits 11 major (Title V) sources, 204 minor sources, and 317 gasoline stations (Stage 1). A major source is one that emits, or has the potential to emit, pollutants over a major source threshold. A minor source is any source which emits fewer pollutants than the major source threshold.
Permitted stationary sources in Mecklenburg County include concrete plants, fabricated metal product manufacturing, chemical plants, printing operations, autobody repair shops, petroleum bulk storage and dispensing facilities. The public can access the
online Air Pollution Facility Database for information concerning permitted stationary sources.
Of the inspections completed in 2015, 94% of facilities were found to be in compliance. The three most commonly cited violations at stationary sources are:
