Evaluation of strategies for airport air pollution control. [Test at Atlanta airport]

Reducing Air Pollutant Emissions at Airports by Controlling Aircraft Ground Operations

“…The first two strategies have been analyzed in previous work. 5 The shutdown of one engine during taxi and the control of departure time are currently being implemented on a limited 6 In evaluating the strategy to tow aircraft at LAX, both arrival and departure aircraft were considered. Taxi routes were identified for towing, since it was assumed that towing would not be implemented over short distances.…”

Emissions of Oxides of Nitrogen from Aircraft

“…Figure 5 shows the impact on predicted annual average NO* concentrations at several places on the Hartsfield International Airport in Atlanta, GA. 5 The data on Figure 5 is divided into concentrations caused by airport sources, and those caused by nonairport sources. The airport sources include aircraft, ground service vehicles, heating plants, and airport access traffic.…”

“…5 In this study, Hartsfield International Airport was used as a representative major airport. Hartsfield is the second busiest commercial aviation airport in the country.…”

“…The range of the WHO recommended standards are 190 to 320 ixg/m 3 hourly average, not to be exceeded more than once per month. Based upon the results of the Argonne study, 5 even with instantaneous conversion of the NO to NO2, one would have to remain in a relatively small area at Hartsfield Airport for more than 1 hr to be exposed to NO2 levels in excess of the lowest of the WHO recommended standards. Moreover, a careful review of the Argonne study will reveal that a 45% reduction in NO* emissions from aircraft would have only a small effect in reducing the potential exposure to NO* levels on the airport property.…”

“…Moreover, a careful review of the Argonne study will reveal that a 45% reduction in NO* emissions from aircraft would have only a small effect in reducing the potential exposure to NO* levels on the airport property. The total NO* emissions from airport sources used in the Argonne analysis 5 was approximately 2600 tons/year (for normal case). This is about equivalent to a 100 megawatt power plant meeting the current New Source Performance Standard (NSPS).…”
