Estimation of Aircraft Emissions for the Corpus Christi International Airport, Corpus Christi, Texas

Estimation of Aircraft Emissions for the Corpus Christi International Airport, Corpus Christi, Texas

Date: May 2013
Creator: Thomas, Gregson Johann
Description: Commercial aviation is a vital part of the United States economy. It generates over $1 trillion annually, which is more than 5% of the U.S. GDP, and produces approximately 10 million jobs. Every year there is an increase in commercial air traffic. This is attributed to expanding trade between states and other countries, which requires larger amounts of cargo aircraft in operation, and also catering to the growing number of middle and upper class passengers who travel for business and pleasure purposes. A rise in commercial aviation leads to the use of more aviation fuel on a monthly and annual basis. This in turn leads to escalated levels of combustion by-products from jet and turbofan engines into the atmosphere. The negative effects of these by-products range from producing poor air quality and consequent health hazards to contributing to global warming. This study is aimed at assessing the impacts of aircraft emissions on the local air quality in Corpus Christi using the Emissions and Dispersion Modeling System. Flight data for the study was obtained from the Department of Transportation's Research and Innovative Technology Administration. Analyses of the emissions were compared on monthly, annual, engine type and airline provider bases. Climatic, economic ...

Air Quality: TVA Plans to Reduce Air Emissions Further, but Could Do More to Reduce Power Demand

Air Quality: TVA Plans to Reduce Air Emissions Further, but Could Do More to Reduce Power Demand

Date: March 8, 2002
Creator: United States. General Accounting Office.
Description: A letter report issued by the General Accounting Office with an abstract that begins "The Tennessee Valley Authority (TVA) relied on its 11 coal-burning plants to supply 60 percent of its electric power in fiscal year 2001. These plants account for almost all of TVA's emissions of two key air pollutants--sulfur dioxide (SO2), which has been linked to reduced visibility, and nitrogen oxides (NOx), which contribute to the formation of harmful ozone. To meet an increase in demand of 1.7 percent annually through 2010, TVA estimates that it will need to expand its current generating capacity of 30,365 megawatts by 500 megawatts annually. Building new generating capacity can produce more emissions, which raises environment concerns. To lessen the need for new capacity, TVA and other electricity suppliers promote the efficient use of electricity through "demand-side management" programs, which seek to reduce the amount of energy consumed or to change the time of day when it is consumed. Even though TVA intends to increase its capacity to generate electricity through 2005, it also expects to reduce its SO2 and NOx emissions during the same time period, primarily by burning lower-sulfur coal, installing devices to control emissions at its existing plants, and ...

Air Quality: Information on Tall Smokestacks and Their Contribution to Interstate Transport of Air Pollution

Air Quality: Information on Tall Smokestacks and Their Contribution to Interstate Transport of Air Pollution

Date: May 11, 2011
Creator: United States. Government Accountability Office.
Description: A letter report issued by the Government Accountability Office with an abstract that begins "Tall smokestacks--stacks of 500 feet or higher, which are primarily used at coal power plants--release air pollutants such as sulfur dioxide (SO2) and nitrogen oxides (NOx) high into the atmosphere to help limit the impact of these emissions on local air quality. Tall stacks can also increase the distance these pollutants travel in the atmosphere and harm air quality and the environment in downwind communities. The 1977 amendments to the Clean Air Act encourage the use of pollution control equipment over dispersion techniques, such as tall stacks, to meet national air standards. Section 123 of the Act does not limit stack height, but prohibits sources of emissions from using the dispersion effects of stack heights in excess of a stack's good engineering practice (GEP) height to meet emissions limitations. GAO was asked to report on (1) the number and location of tall stacks of 500 feet or higher at coal power plants and when they began operating; (2) what is known about such stacks' contribution to the interstate transport of air pollution and the pollution controls installed at plants with these stacks; and (3) the number ...
