Description:
In recent years, a large number of health studies have identified increased risks of adverse health effects for populations spending significant time near major roads. These studies indicate that populations living, working or going to school near major roads may be subjected to an increased risk for adverse effects including respiratory, cardiovascular, premature mortality, birth and developmental effects, and cancer. Emission inventories reveal that mobile sources significantly contribute to local and national concentrations of a number of air pollutants. Air quality monitoring studies near large roadways have measured pollutant concentrations that are elevated above overall urban background concentrations. The EPA recently published monitoring requirements in support of the revision to the primary NO2 National Ambient Air Quality Standards (NAAQS). As part of the rulemaking, certain state and local air agencies are required to operate near-road NO2 monitors. EPA committed to prepare near-road monitoring assistance documents and assist state and local air monitoring agencies as they conduct pilot studies to further aid in the implementation of required near-road monitoring stations. This presentation will provide an update on the monitoring requirements, technical assistance document, and preliminary pilot study results.
