We owe you an explanation.

June 19: An important update for readers in the United States.

You deserve an explanation, so please don't skip this 1-minute read. It's Friday, June 19, and you only had a small chance of seeing our message. This year, Wikipedia has seen fewer visitors and fewer new supporters, so your visit today means a lot. We hope that Wikipedia has given you at least $2.75 of knowledge recently. If everyone who finds Wikipedia useful gave $2.75, we'd hit our goal in a few hours.

It's been 25 years and Wikipedia is still free. It's still created by people, not machines, and we don't run ads or put up paywalls because we're not here to make a profit off your attention. In other words, it's still the internet we were promised.

Less than 2% of our readers donate, so if you've never given and Wikipedia has provided you with at least $2.75 worth of knowledge, donate today. If you are undecided, remember any contribution helps.

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.[6][7][8] 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.[9]

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.[10]

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.[11][9]

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.[12] 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).[6]

Programs & Activities

Programs

[ edit]

EPA established its major programs pursuant to the primary missions originally articulated in the laws passed by Congress. Additional programs have been developed to interpret the primary missions. Some of the newer programs have been specifically authorized by Congress.[143] Former administrator William Ruckelshaus observed in 2016 that a danger for EPA was that air, water, waste and other programs would be unconnected, placed in "silos", a problem that persists more than 50 years later, albeit less so than at the start.[144]

Core programs

[ edit]

Air quality and radiation protection

[ edit]

The Office of Air and Radiation (OAR) describes itself as the official authority in charge of "developing national programs, policies, and regulations for controlling air pollution and radiation exposure." The OAR is responsible for enforcing the Clean Air Act, the Atomic Energy Act, the Waste Isolation Pilot Plant Land Withdrawal Act, and other applicable laws. The OAR is in charge of the Offices of Air Quality Planning and Standards, Atmospheric Protection, Transportation and Air Quality, and the Office of Radiation and Indoor Air.[125]
