Environment Protection Agency (EPA) mission is to protect human health and to safeguard the natural environment -- air, water and land -- upon which life depends.
The U.S. Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the United States federal government which was created for the purpose of protecting human health and the environment by writing and enforcing regulations based on laws passed by Congress. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the president and approved by Congress. The current administrator is Lisa P. Jackson. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank.
The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions, and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tribal, and local governments. It delegates some permitting, monitoring, and enforcement responsibility to U.S. states and Native American tribes. EPA enforcement powers include fines, sanctions, and other measures. The agency also works with industries and all levels of government in a wide variety of voluntary pollution prevention programs and energy conservation efforts.
The agency has approximately 17,000 full-time employees. and engages many more people on a contractual basis. More than half of EPA human resources are engineers, scientists, and environmental protection specialists; other groups include legal, public affairs, financial, and information technologists.
In 1992 the EPA launched the Energy Star program, a voluntary program that fosters energy efficiency.
EPA administers the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) (which is much older than the agency) and registers all pesticides legally sold in the United States.
The Air Quality Modeling Group (AQMG) is in the EPA's Office of Air and Radiation (OAR) and provides leadership and direction on the full range of air quality models, air pollution dispersion models and other mathematical simulation techniques used in assessing pollution control strategies and the impacts of air pollution sources.
The AQMG serves as the focal point on air pollution modeling techniques for other EPA headquarters staff, EPA regional Offices, and State and local environmental agencies. It coordinates with the EPA's Office of Research and Development (ORD) on the development of new models and techniques, as well as wider issues of atmospheric research. Finally, the AQMG conducts modeling analyses to support the policy and regulatory decisions of the EPA's Office of Air Quality Planning and Standards (OAQPS).
The AQMG is located in Research Triangle Park, North Carolina.
EPA ensures safe drinking water for the public, by setting standards for more than 160,000 public water systems throughout the United States. EPA oversees states, local governments and water suppliers to enforce the standards, under the Safe Drinking Water Act. The program includes regulation of injection wells in order to protect underground sources of drinking water.
Radiation Protection EPA has following seven groups of projects to protect public from nuclear contamination.
- Waste Management Programs
- Emergency Preparedness and Response Programs
- Protective Action Guide
- Risk Assessment and Federal Guidance Programs
- Radiation Source Reduction and Management
