EPA was founded December 2, 1970, employs 17,000 people across the country & deals with United States environmental issues both domestically & abroad. President Richard Nixon proposed & Congress supported "a strong, independent agency."​ that viewed "the environment as a whole."​ The President's charge to the first EPA Administrator [a 38-year-old Assistant Attorney General named William Ruckelshaus] was to treat "air pollution, water pollution and solid wastes as different forms of a single problem."​ The main purpose of the reorganization giving birth to EPA was to introduce a "broad systems approach [that]...would give unique direction to our war on pollution."​ Ruckelshaus said that he & EPA were starting with "no obligation to promote commerce or agriculture."​ By promising to enforce "reasonable standards of air quality,"​ Ruckelshaus positioned himself as the government advocate of environmental progress; not merely a mediator between industry & the public. In fact, he envisioned for EPA a crucial role in the "development of an environmental ethic"​ among businessmen & citizens alike. EPA employees work at: HQ in Washington, DC, 10 regional offices [Boston, New York, Philadelphia, Atlanta, Chicago, Dallas, Kansas City, Denver, San Francisco, & Seattle] & more than two dozen labs & field offices across the 50 states & 6 territories. EPA staff is highly educated, motivated & technically trained. More than half are engineers, scientists, & policy analysts. Many are also legal, public affairs, financial, information management & computer specialists. Only NASA staff hold more advance degrees than do EPA staff. EPA develops regulation & enforces [both civilly & criminally] statutes protecting human health & the environment. EPA promotes technical assistance & international coordination on environmental issues. EPA researches & sets standards for environmental programs & delegates those programs to states to assist in & perhaps one day take over EPA's mission.
