| Abstract |
The Federal Clean Air Act assigns to the United States Environmental Protection Agency (EPA) the responsibility to promulgate National Ambient Air Quality Standards (NAAQS) regarding carbon monoxide (CO). On August 8, 1980 EPA proposed CO standards of 25 parts per million (ppm) maximum allowable one hour expected concentration level and 9 ppm maximum allowable expected eight hour average concentration level. In an effort to achieve these standards the Clean Air Act also assigns to EPA the responsibility to promulgate regulations regarding the amount of CO new highway vehicles may emit from the tailpipe. To properly fulfill this second mandate, it is necessary to understand the conditions associated with high ambient CO concentrations. The five studies summarized in this report provide information on recent CO emission inventory estimates, the meteorological conditions associated with high ambient CO concentrations, the distribution of CO concentrations within selected cities, the effects on CO concentration levels of both meteorological conditions and traffic characteristics at typical hot spot locations and the estimated amount that in-use vehicle emissions must be reduced to achieve the NAAQS for CO. |
