Office of Transportation and Air Quality (OTAQ)

What We Do

OTAQ’s mission is to  protect human health and the environment by reducing air pollution and greenhouse gas emissions from mobile sources and the fuels that power them, advancing clean fuels and technology, and encouraging business practices and travel choices that minimize emissions. OTAQ’s programs address emissions from the range of mobile sources:  cars and light trucks, large trucks and buses, farm and construction equipment, lawn and garden equipment, marine engines, aircraft, and locomotives.

OTAQ primary activities include:

  • Assessing mobile source-related air quality problems and developing sophisticated modeling tools to develop solutions, measure results, and support emission inventories.
  • Establishing national standards to reduce emissions from on-road and nonroad mobile sources of pollution.
  • Implementing national mobile source standards through certification processes and in-use monitoring strategies.
  • Developing fuel efficiency programs and technologies to reduce the emission of greenhouse gases from the transportation sector.
  • Researching, evaluating, and developing advanced technologies for controlling emissions, as well as developing new strategies for improving fuel efficiency.

OTAQ's National Vehicle and Fuel Emissions Laboratory provides OTAQ with emissions testing services in support of rulemakings, certification, enforcement actions, and test procedures development.

Office of Radiation and Indoor Air (ORIA)

What We Do

ORIA’s mission is to protect the public and the environment from the risks of radiation and indoor air pollution. The office coordinates across the Agency and with other federal, state, tribal, and non-governmental organizations to carry out its mission. ORIA develops criteria, standards, guidance, policies, and programs to limit unnecessary radiation exposure and control exposure to indoor air pollutants.  The Office:

  • provides technical assistance to states and tribes through EPA's Regional offices, and to other national and international organizations having radiation and indoor air protection programs;
  • directs an environmental radiation monitoring program;
  • responds to radiological emergencies; and
  • evaluates and assesses the overall risk and impact of radiation and indoor air pollution.
