Evaluation of Emission Control Strategies for Airfield Operations at the Los Angeles and San Francisco International Airports.

摘要

This report reviews potential air pollutant emission reductions which could be achieved by various strategies to control airfield operations at Los Angeles and San Francisco International Airports,and examines safety problems,cost impacts,potential fuel savings,time frame for strategy implementation,and potential regulatory and jurisdictional conflicts associated with each strategy. Airfield emission sources studied included aircraft operation in the idle,taxi,takeoff,and landing modes;ground service vehicles;fuel handling and storage;and aircraft engine maintenance. Nineteen potential strategies were identified,and seven strategies were selected for detailed analysis and examination after a preliminary evaluation. Two strategies,aircraft towing and reducing the number of operating engines on the ground,appear to provide the most significant emission reduction. Both of these strategies offer potential reductions in the range of 20to 40percent of the carbon monoxide and nitrogen oxides which are currently emitted by ground operations. The aircraft towing strategy also offers a comparable improvement in suspended particulate matter emissions. When the overall feasibility of each strategy is evaluated,the strategy to reduce the number of operating engines appears to be the most viable since its implementation would result in fuel savings,no apparent safety problems,and it can be implemented immediately.
