The U.S. Environmental Protection Agency's (EPA) Office of
Transportation and Air Quality (OTAQ) maintains a site on the Internet's
World Wide Web to provide up-to-date information on the Federal
Government's efforts to meet the mobile source provisions of the Clean
Air Act.
What does OTAQ do?
OTAQ is responsible for controlling emissions from motor vehicles,
farm and construction equipment, marine engines, aircraft, locomotives,
and other mobile sources of air pollution. OTAQ also conducts research
on the effects of different fuels on pollution from these engines.
How can I access the OTAQ Web site?
You can access the OTAQ home page directly by typing the Uniform
Resource Locator (URL) http://www.epa.gov/otaq. You can also access it
from the EPA's Internet home page at http://www.epa.gov by selecting
"Offices, Labs and Regions," then selecting "Air and Radiation," and
then selecting the "Automobiles" graphic.
