Secondary Roadways Pollution Workshop

Workshop on Air Pollution Impacts of Secondary Roadways and their Mitigation
January 24, 2008
UC Davis

EPA Region IX with the support of Breathe California of Sacramento-Emigrant Trails, the Sacramento Metropolitan AQMD, and the UC Davis DELTA Group and Air Quality Research Center held a small invitation-only meeting on the UC Davis campus on January 24, 2008, on the topic of near road (mostly non-freeway) air pollution impacts and mitigation strategies. The purpose of this workshop was to share new data being developed by several agencies. Presentations are not academic discussions but rather summaries of a few recent and important findings and their implications for planning.
