The Air Quality Planning Section is responsible for the development and implementation of air quality plans and policies.  The primary functions performed by the Planning Division include: plan development, emissions inventories, air quality computer modeling and mobile sources programs.

Planning staff prepare long-term planning documents and reports, and conduct studies related to the criteria pollutants.  Plans and reports include State Implementation Plans (SIPs), Progress Reports, and Exceptional Event packages for Maintenance Areas in Clark County.  Long-term plans demonstrate how Clark County will meet and continue to maintain compliance with the National Ambient Air Quality Standards (NAAQS).  So far, plans developed in Clark County consist of those for Particulate Matter (PM10), Ozone (O3) and Carbon Monoxide (CO).

The emissions inventory and modeling staff compile emissions inventories of air pollutant emissions from all sources within Clark County. These staff use computer models to simulate dispersion and formation of pollutants in the atmosphere to help demonstrate compliance and identify pollutant sources that require control.

The mobile sources program staff develop and implement programs to reduce emissions from mobile sources. These include cars, trucks, buses, construction equipment, RVs, off-road vehicles, and lawn or garden equipment. The program also includes identifying the air quality impacts of transportation issues, which include vehicle inspection and maintenance, clean fuels, and highway construction. The section also assists in the development of transportation conformity analysis and transportation planning.
