Air Pollution: Meeting Future Electricity Demand Will Increase Emission of Some Harmful Substances

Air Pollution: Meeting Future Electricity Demand Will Increase Emission of Some Harmful Substances

Date: October 30, 2002
Creator: United States. General Accounting Office.
Description: A letter report issued by the General Accounting Office with an abstract that begins "Electric power plants burn fuels that can produce harmful emissions, such as carbon dioxide, mercury, nitrogen oxides, and sulfur dioxide, which can pose human health and environmental risks. To assess the potential risks of meeting future electricity demand, congressional committees asked GAO to (1) report on the Energy Information Administration's (EIA's) national and regional projections of such emissions by 2020, and (2) determine how the projections would change using alternative assumptions about future economic growth and other factors that advisers in these fields recommended. GAO also assessed the potential effects of future electricity demand on water demand and supply."

Air Pollution: Emissions from Older Electricity Generating Units

Air Pollution: Emissions from Older Electricity Generating Units

Date: June 12, 2002
Creator: United States. General Accounting Office.
Description: A letter report issued by the General Accounting Office with an abstract that begins "Although fossil fuels--coal, natural gas, and oil--account for more than two thirds of the nation's electricity, generating units that burn these fuels are major sources of airborne emissions that pose health and environmental risks. To limit emissions and protect air quality, the Environmental Protection Agency regulates emissions of sulfur dioxide and nitrogen oxides from a variety of sources including electricity generating units that burn fossil fuels, other industrial sources, and automobiles. Older electricity generating units--those that began operating before 1972--emit 59 percent of the sulfur dioxide, 47 percent of the nitrogen oxides, and 42 percent of all electricity produced by fossil-fuel units. Units that began operating in or after 1972 are responsible for the remainder of the emissions and electricity production. For equal quantities of electricity generated, older units, in the aggregate, emitted twice as much sulfur dioxide and 25 percent more nitrogen oxides than newer units which must meet the new source standards for these substances. Older and newer units emitted about the same amount of carbon dioxide for equal quantities of electricity generated. Of the older units, those in the Mid-Atlantic, Midwest, and Southeast ...

Air Pollution: EPA's Actions to Resolve Concerns with the Fine Particulate Monitoring Program

Date: August 12, 1999
Creator: United States. General Accounting Office.
Description: A letter report issued by the General Accounting Office with an abstract that begins "Pursuant to a congressional request, GAO reviewed the National Academy of Sciences March 1998 report on the Environmental Protection Agency's (EPA) plans to monitor particulate matter smaller than 2.5 microns (PM2.5), focusing on: (1) EPA's actions in response to the Academy's concerns with the planned PM2.5 monitoring program; and (2) the challenges that state and local agencies face in establishing and operating the PM2.5 monitoring program, as well as EPA's response to these challenges."

Air Pollution: EPA Should Improve Oversight of Emissions Reporting by Large Facilities

Air Pollution: EPA Should Improve Oversight of Emissions Reporting by Large Facilities

Date: April 6, 2001
Creator: United States. General Accounting Office.
Description: A letter report issued by the General Accounting Office with an abstract that begins "The Environmental Protection Agency (EPA) performs limited oversight of states' processes for verifying the accuracy of large industrial facilities' emissions reports. EPA's data show that most emissions determinations from large sources are based on generic emissions factors. Although EPA allows facilities to estimate their emissions in this manner, EPA officials generally consider direct methods to be more reliable. The accuracy of these reports is important because they influence (1) the financing of states' regulatory programs through fees and (2) the development of emissions inventories, which, in turn, help regulators to develop control strategies and establish permit limits. Furthermore, steps taken to assess the accuracy of these reports, such as more thoroughly reviewing the supporting information, could improve compliance with Clean Air Act requirements. For example, a more thorough review of the information underlying a facility's emission reports, or a more systematic comparison of these reports over time, could identify increased emissions. Such indications could, in turn, trigger a review of compliance with new source review requirements, an area in which EPA found widespread noncompliance in four industries. In the four states that GAO reviewed, the states ...

Air Pollution: Air Quality and Respiratory Problems in and Near the Great Smoky Mountains

Air Pollution: Air Quality and Respiratory Problems in and Near the Great Smoky Mountains

Date: May 25, 2001
Creator: United States. General Accounting Office.
Description: Testimony issued by the General Accounting Office with an abstract that begins "Concerns have been growing about the air quality, visibility, and respiratory illnesses around the Great Smoky Mountains National Park, which straddles the border between North Carolina and Tennessee. This testimony analyzes recent trends in and contributing factors to (1) visibility impairments, (2) ground-level ozone, and (3) respiratory illnesses. This testimony also examines the Tennessee Valley Authority's (TVA) plans to reduce its emission of regulated pollutants. Visibility impairments and ozone are largely attributable to the following three types of emissions: sulfur dioxide, nitrogen oxides, and volatile organic compounds. The counties that border the park generally have slightly higher mortality rates from two types of respiratory illness. The three types of emissions interact in the atmosphere to form ozone gas and sulfate particles, which are linked to respiratory illnesses. In response to federal laws and other factors, TVA is making substantial environment-related investments and expects to reduce its annual emissions of sulfur dioxide by 36 percent and its "ozone-season" emissions of nitrogen oxides by 68 percent between 1999 and 2005. This testimony summarizes a May report, (GAO-01-658)."

Ozone

Ozone

Date: 2002
Creator: NASA Earth Observatory
Description: In the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O2), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high-energy ultraviolet rays are completely absorbed in the stratosphere.

Ozone

Date: 2002
Creator: NASA Earth Observatory
Description: The amount and distribution of ozone molecules in the stratosphere varies greatly over the globe. Ozone molecules are transported around the stratosphere much as water clouds are transported in the troposphere. Therefore, scientists observing ozone fluctuations over just one spot could not know whether a change in local ozone levels meant an alteration in global ozone levels, or simply a fluctuation in the concentration over that particular spot. Satellites have given scientists the ability to overcome this problem because they provide a picture of what is happening daily over the entire Earth.

Carbon Monoxide from California Fires

Date: November 4, 2003
Creator: NASA Earth Observatory
Description: Large fires can be blamed for some polluted air. In addition to ash and smoke, fires release carbon monoxide into the atmosphere as they burn. This false-color image shows the atmospheric column of carbon monoxide, with yellow and red indicating high levels of pollution. (The gray areas show where no data were taken, likely due to cloud cover.) The data were taken by the Measurements Of Pollution In The Troposphere (MOPITT) instrument aboard NASA's Terra satellite for the period October 26-31, 2003.
