Description: The Clean Air Act empowers the U.S. Environmental Protection Agency (EPA) to set the National Ambient Air Quality Standards (NAAQS) on harmful air pollutants. There are six criteria pollutants regulated by NAAQS (http://www.epa.gov/air/criteria.html): ozone, particulate matter, nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. Our research studies spatial and temporal patterns in air pollutant concentrations and seeks to identify the most critical sources, locations, and time periods to target for control actions. Many metropolitan regions, including Houston and Dallas-Fort Worth, currently violate the federal ozone pollution standard set by the EPA. For the Dallas-Fort Worth Metroplex, we work with the CAMx (Comprehensive Air Quality Model with extensions) model used by state decision-makers at the Texas Commission for Environmental Quality, and we are studying potential ozone control strategies provided by the North Central Texas Council of Govenments, as part of the State Implementation Plan.
