                 The U.S. Environmental Protection Agency's (EPA) Office of Mobile
                 Sources (OMS) is responsible for carrying out laws to control air
                 pollution from motor vehicles, engines, and their fuels. OMS is divided
                 between EPA's headquarters in Washington, D.C., and the National
                 Vehicle and Fuel Emissions Laboratory (NVFEL) in Ann Arbor,
                 Michigan.

Overview
The Laboratory's primary responsibilities include:

  •  developing national regulatory programs to reduce mobile source
     related air pollution from light-duty cars and trucks, heavy-duty
     trucks and busses, and nonroad engines and vehicles.

  •  evaluating emission control technology.

  •  providing state and local air quality regulators and transportation
     planners with access to critical information on transportation pro-
     grams and incentive-based programs.

  •  testing vehicles, engines and fuels.

  •  determining compliance with federal emissions and fuel economy
     standards.

Organizationally, the lab functions as part of EPA's Washington, D.C.,
headquarters.

The laboratory was established in 1971, shortly after the creation of
EPA. It is located in Ann Arbor, Michigan, near the headquarters of
domestic automobile manufacturers to facilitate transfer of test vehicles
back and forth.

There are about 400 federal and contract employees atNVFEL. Staff
expertise spans a variety of technical and public policy fields including
auto mechanics, engineering, chemistry,  economics, natural  resources
management, and law.

The NVFEL lab provides the Office of Mobile Sources with emission
testing services for motor vehicle, heavy-duty engine, and nonroad
engine programs in support of rulemakings, enforcement actions, and
procedures development. Testing activities include:

  • certifying that vehicles and engines meet federal emissions and fuel
    economy standards.

  • analyzing fuels,  fuel additives, and exhaust compounds.

  • testing engines for in-use compliance.

In addition, the lab assists in the development of automotive technology
to reduce conventional pollutants and greenhouse gas emissions, such as
Clean Car (Partnership for a New Generation of Vehicles), low NOx
diesel engine, and alternative fuel technologies.
