REVIEW OF U.S. ENVIRONMENTAL PROTECTION AGENCY GUIDELINES FOR EVALUATING INDIRECT SOURCES AND CARBON MONOXIDE HOT SPOTS

Two guides have been developed to aid in identifying locations where significant carbon monoxide concentrations can be attributed to mobile source emissions. Both guides use state-of-art traffic engineering practices, emission factors, and dispersion techniques to provide a comprehensive yet manageable analysis of carbon monoxide concentration impacts. One guideline is oriented to indirect sources (e.g., shopping malls or sports stadiums) and provides a comprehensive manual methodology for assessing both 1- and 8-h average carbon monoxide concentration impacts corresponding to the national ambient air quality standards time averages. The second, or hot-spot guidelines, is designed to assess urban problems and employs a more general approach for estimating carbon monoxide concentrations at individuals roadways and intersections. The term hot sport is used to indicate locations where carbon monoxide concentrations are estimated to be above the national ambient air quality standards. Both guidelines use a series of annotated worksheets, graphs, and tables, which are supplemented by background information on technique development and applications. Results of limited validation studies are included in each guide. These guidelines are particularly useful in evaluating indirect sources, planning transportation controls, assessing new roadway projects, and evaluating and selecting air quality monitoring sites. /Author/
