Abstract: Air Quality in Southern Nevada has had the attention of the public and the media for decades. Severe non-attainment status with particulate matter (PM10) and carbon monoxide (CO) levels have presented the longest-running issues. Attainment of the National Ambient Air Quality Standards (NAAQS) is the yardstick by which progress is measured in reducing levels of air contaminants. Clark County has achieved attainment of the CO NAAQS after many years of control efforts. Similar progress has been made with coming into attainment status for particulate matter 10 microns and smaller (PM10) and will be complete with the submittal and acceptance of a PM10 maintenance plan and re-designation to attainment. Ozone (O3) levels in comparison to the NAAQS are now an issue of high priority in Clark County. Ozone sources and precursors (primarily volatile organic compounds (VOC) and oxides of nitrogen (NOx)) that frequently impact Clark County are located throughout the Region, and occasionally even further. Extensive pollutant monitoring, inventories of sources, and modeling of data are needed to demonstrate compliance with O3 standards, as well as for development and implementation of control methods and requirements to work toward attainment status of ozone.

The functions of the Clark County Department of Air Quality designated by the Environmental Protection Agency are described. Status of attainment of the various NAAQS for Clark County will be presented.
