Near-road NO2 Monitoring Technical Assistance Document

On February 9, 2010, the U.S. Environmental Protection Agency (EPA) promulgated new minimum monitoring requirements for the nitrogen dioxide (NO2) monitoring network in support of a newly revised 1-hour NO2 National Ambient Air Quality Standards (NAAQS) and the retained annual NAAQS. In the new monitoring requirements, state and local air monitoring agencies are required to install near-road NO2 monitoring stations at locations where peak hourly NO2 concentrations are expected to occur within the near-road environment in larger urban areas. State and local air agencies are required to consider traffic volumes, fleet mix, roadway design, traffic congestion patterns, local terrain or topography, and meteorology in determining where a required near-road NO2 monitor should be placed. This document is the June 2012 release of the Near-Road NO2 Monitoring Technical Assistance Document (TAD). The TAD was developed to aid state and local air monitoring agencies in the implementation of required near-road NO2 monitoring stations. The TAD reflects the collaboration between partner state and local air monitoring agencies and associations, partnering state departments of transportation, the Federal Highways Administration, and the EPA. This document also reflects feedback, concepts, and suggestions from two reviews conducted by the Clean Air Scientific Advisory Committee (CASAC) Ambient Monitoring and Methods Subcommittee (AMMS).
