5. What are the Causes Ozone and particle pollution can occur from several different sources including point source pollution (power plants and factories), area sources (dry cleaning and gas stations), non-road sources (lawn mowers, airplanes, and boats) and mobile sources (trucks, cars, buses, and motorcycles) (Clean Air Partners, n.d.). In the Virginia-DC-Maryland region, the main sources of VOC emissions are from area sources at 49 percent, while mobile sources contribute to 50 percent of the NOx emissions (Clean Air Partners, n.d.). As populations in the county continue to increase, the number of vehicle miles traveled each day increases. The extensive use of motorized vehicles has significantly attributed to the non-attainment of ozone and particle pollution. Additionally, a significant number of vehicles in Virginia do not meet vehicle emission standards (Fairfax County EQAC, 2014). Other sources of air pollution include utilities, stationary sources, and non-road construction vehicle, however various studies have determined that the ozone problem originates west of the region and is beyond the regulatory control of Virginia (Fairfax County, 2014). Sources of particle pollution include motor vehicles, power plants, construction sites, commercial business, agricultural sources, and wood burning (Fairfax County, 2014). 5.1. Social, Economic, and Environmental Perspectives Air pollution can affect the environmental, human health, and the economy. Ground-level ozone is extremely toxic and corrosive; people who are continuously exposed to ozone can experience permeant respiratory issues (West, n.d.). Ozone is particularly dangerous for sensitive populations including children and seniors. There are significant added he... ... middle of paper ... ...generally specifies requirements as stated in the CAA. 6.1. Regulating Ozone and Particle Pollution Overall, Fairfax County has been successful in reducing air quality pollutants for ozone and particle pollution. Throughout Fairfax County and the region, air-monitoring stations have been setup to provide continual monitoring of air pollutants. The Office of Air Quality Monitoring (AQM) is responsible for operating and maintaining the network of air quality monitors throughout Fairfax County and Virginia (Virginia DEQ, 2014). In addition to the continual monitoring, the DEQ conducts compliance inspections and records information about violations (Fairfax County EQAC, 2014). Virginia and the metropolitan Washington region have also developed a State Implementation Plan outlining a plan to attain and maintain air quality levels within CAA and NAAQS requirements.
