Ambient Air Quality Surveillance (Renewal)

The data collected through this information collection consist of ambient air concentration measurements for the seven air pollutants with national ambient air quality standards (i.e., ozone, sulfur dioxide, nitrogen dioxide, lead, carbon monoxide, PM2.5 and PM10), ozone precursors, meteorological variables at a select number of sites and other supporting measurements. Accompanying the pollutant concentration data are quality assurance/quality control data and air monitoring network design information. The U.S. EPA and others (e.g., state and local air quality management agencies, tribal entities, environmental groups, academic institutions, industrial groups) use the ambient air quality data for many purposes. Some of the more prominent uses include informing the public and other interested parties of an areas air quality, judging an areas (e.g., county, city, neighborhood) air quality in comparison with the established health or welfare standards (including both national and local standards), evaluating an air quality management agency's progress in achieving or maintaining air pollutant levels below the national and local standards, developing and revising State Implementation Plans (SIPs) in accordance with 40 CFR 51, evaluating air pollutant control strategies, developing or revising national control policies, providing data for air quality model development and validation, supporting enforcement actions, documenting episodes and initiating episode controls, air quality trends assessment, and air pollution research.
