The Environmental Protection Agency (EPA) is an independent agency of the United States government tasked with environmental protection matters. President Richard Nixon proposed the establishment of EPA on July 9, 1970; it began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was sent to the House and Senate in accordance with the Reorganization Act of 1949, in which they had 60 days to pass a disapproval resolution or the order would take effect. Congress did not pass a disapproval resolution, and the order establishing the EPA went into effect. The agency is led by its administrator, who is appointed by the president and approved by the Senate. Since January 29, 2025, the administrator is Lee Zeldin. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank. The EPA has its headquarters in Washington, D.C. There are regional offices for each of the agency's ten regions, as well as 27 laboratories around the country. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of U.S. environmental laws, in consultation with state, tribal, and local governments. EPA enforcement powers include fines, sanctions, and other measures. It delegates some permitting, monitoring, and enforcement responsibility to U.S. states and the federally recognized tribes. 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's budgeted employee level in 2023 was 16,204.1 full-time equivalent (FTE). More than half of EPA's employees are engineers, scientists, and environmental protection specialists; other employees include legal, public affairs, financial, and information technologists.
History
Background
Beginning in the late 1950s and through the 1960s, the US Congress reacted to increasing public concern about the impact that human activity could have on the environment. Senator James E. Murray introduced a bill, the Resources and Conservation Act (RCA) of 1959, in the 86th Congress. The bill would have established a Council on Environmental Quality in the Executive Office of the President, declared a national environmental policy, and required the preparation of an annual environmental report. The conservation movement was weak at the time and the bill did not pass Congress. The 1962 publication of Silent Spring, a best-selling book by Rachel Carson, alerted the public about the detrimental effects on animals and humans of the indiscriminate use of pesticide chemicals. In the years following, Congress discussed possible solutions. In 1968, a joint House–Senate colloquium was convened by the chairmen of the Senate Committee on Interior and Insular Affairs, Senator Henry M. Jackson, and the House Committee on Science and Astronautics, Representative George P. Miller, to discuss the need for and means of implementing a national environmental policy. Congress enacted the National Environmental Policy Act of 1969 (NEPA) and the law was based on ideas that had been discussed in the 1959 and subsequent hearings. The Richard Nixon administration made the environment a policy priority in 1969–1971 and created two new agencies, the Council on Environmental Quality (CEQ) and EPA. Nixon signed NEPA into law on January 1, 1970. The law established the CEQ in the Executive Office of the President. NEPA required that a detailed statement of environmental impacts be prepared for all major federal actions significantly affecting the environment. The "detailed statement" would ultimately be referred to as an environmental impact statement (EIS).
Establishment
On July 9, 1970, Nixon proposed an executive reorganization that consolidated many environmental responsibilities of the federal government under one agency, a new Environmental Protection Agency. This proposal included merging pollution control programs from a number of departments, such as the combination of pesticide programs from the United States Department of Agriculture and the United States Department of the Interior. After conducting hearings during that summer, the House and Senate approved the proposal. The EPA was created 90 days before it had to operate, and officially opened its doors on December 2, 1970. The agency's first administrator, William Ruckelshaus, took the oath of office on December 4, 1970. EPA's primary predecessor was the former Environmental Health Divisions of the U.S. Public Health Service (PHS), and its creation caused one of a series of reorganizations of PHS that occurred during 1966–1973. From PHS, EPA absorbed the entire National Air Pollution Control Administration, as well as the Environmental Control Administration's Bureau of Solid Waste Management, Bureau of Water Hygiene, and part of its Bureau of Radiological Health. It also absorbed the Federal Water Quality Administration, which had previously been transferred from PHS to the Department of the Interior in 1966. A few functions from other agencies were also incorporated into EPA: the formerly independent Federal Radiation Council was merged into it; pesticides programs were transferred from the Department of the Interior, Food and Drug Administration, and Agricultural Research Service; and some functions were transferred from the Council on Environmental Quality and Atomic Energy Commission. Upon its creation, EPA inherited 84 sites spread across 26 states, of which 42 sites were laboratories. The EPA consolidated these laboratories into 22 sites.
