                   The U.S. Environmental Protection Agency's (EPA) Office of Mobile
                   Sources (OMS) 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 Is the OMS Web Site?

                  The OMS Web Site is the official Internet World Wide Web (WWW)
                  location for information from EPA's Office of Mobile Sources. OMS is
                  responsible for controlling emissions from motor vehicles, farm and
                  construction equipment, marine engines, aircraft, locomotives, and other
                  mobile sources of air pollution. OMS also conducts research on the
                  effects of different fuels on pollution from these engines.
                  How Can One Access the OMS Web Site?

                  The OMS Home Page can be accessed directly by typing the Uniform
                  Resource Locator (URL) http://www.epa.gov/oms. The OMS Web Site
                  can also be accessed 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.

The OMS Web site was developed in August 1995 to replace the OMS area of TTN and
meet the needs of an increasing number of people who look to the World Wide Web to
find information quickly in electronic form.
