1 Near-road NO 2 Monitoring Pilot Study Boise, Idaho Bruce Louks, Steve Miller, Mary Walsh, Michael Toole, Ed Jolley, Leah Arnold, Matthew Garringer Idaho Department of Environmental Quality 212 NW Airquest Annual Meeting Pullman, WA 1

2 Pilot Study Objectives Site selection process Assist with EPA s Technical Assistance Document Participate in National Passive Monitoring Study Follow CASAC AAMS recommendations for additional parameters and evaluation of new technologies and instruments Assess/reconcile near-road effects on ambient air pollutant concentrations 2

3 Network and Site Selection What information is needed? AADT for major roads in the area AADT for local roadways * Fleet mix data * Congestion Patterns * Existing NO2 Monitor Locations Prevailing wind patterns Population density maps Locations of schools and/or vulnerable and susceptible populations * *data may be available only from local sources 3
