	Clean Air Act - Wikipedia, the free encyclopedia
		A Clean Air Act describes one of a number of pieces of legislation relating to the reduction of smog and atmospheric pollution in general.
		The United States Congress passed the Clean Air Act in 1963, the Clean Air Act Amendment in 1966, the Clean Air Act Extension in 1970, and Clean Air Act Amendments in 1977 and 1990.
		Additionally the Clean Air Act and state statutes have led to widespread use of atmospheric dispersion models, including point source models, roadway air dispersion models and aircraft air pollution models in order to analyze air quality impacts of proposed major actions.

	Clean Air Act
		The Clean Air Act is a federal law that was implemented to assure all Americans clean air to breathe.
		The Clean Air Act has established guidelines and goals for industrial sources, power plants, and automobile manufactories to follow to decrease their amount of air pollution and emissions and to improve the clean air quality.
		Yet, research indicates that the public is largely unaware of this clean air progress and believes that the amount of clean air has decreased and the air quality is deteriorating.

	clean air #1
		The Clean Air Act of 1990 addressed five main areas: air-quality standards, motor vehicle emissions and alternative fuels, toxic air pollutants, acid rain, and stratospheric ozone depletion.
		This act also recognized the dangers of motor vehicle exhaust, and it encouraged the development of emissions standards from these sources as well as from stationary sources.
		Interstate air pollution from the use of high sulfur coal and oil also needed to be reduced; therefore, this act encouraged the use of technology which removed sulfur from these fuels.

		The Clean Air Act is a federal law covering the entire country, the states do much of the work to carry out the Act.
		For instance, an electric power plant may be covered by the acid rain, hazardous air pollutant and non-attainment (smog) parts of the Clean Air Act; the detailed information required by all these separate sections will be in one place--on the permit.
		The deadlines in the 1990 Clean Air Act were designed to be more realistic than dead- lines in previous versions of the law, so it is more likely that these deadlines will be met.

	CLEAN AIR ACT
		The 1990 Clean Air Act Amendments are a landmark effort to reduce air pollution through a variety of instruments including the use of a market based system of tradeable pollution "permits" under Title IV and Title V. Recently, however, enforcement has lagged because of Congressional resistance.
		Air Quality Criteria Documents for sulfur oxides and particulates were issued two years after the passage of the bill and criteria documentation for HCs, CO, and oxidants were not ready until 1970 and NOx criteria were not issued until 1971.
		Clean air legislation languished almost untouched during the Reagan administration even though pollution continued to be a significant voter concern.

	Clean Air Act
		Clean Air Act (42 USC 7401-7661; P.L. 104-59 and P.L. The majority of the amendments to the Clean Air Act were enacted in 1977 and are known as the Clean Air Amendments of 1977 (P.L. 95-95; 91 Stat.
		The primary objective of the Clean Air Act is to establish Federal standards for various pollutants from both stationary and mobile sources and to provide for the regulation of polluting emissions via state implementation plans.
		In addition, the amendments are designed to prevent significant deterioration in certain areas where air quality exceeds national standards, and to provide for improved air quality in areas which do not meet Federal standards ("nonattainment" areas).

		A characterization of the air emissions associated with the petroleum refining process, and the significance of the environmental problem which EPA intends to address through regulation are assessed.
		During the air oxidation reactor and distillation processes, the waste gas stream is deficient in air.
		Having a large amount of excess air (i.e., in excess of the required stoichiometric amounts) may be costly, but any mixture within the flammability limits, on either the fuel-rich or fuel-lean side of the stoichiometric mixture, is considered a fire hazard as a feed stream to the incinerator.

		Throughout the history of the Clean Air Act, questions have been raised as to whether the health and environmental benefits of air pollution control justify the costs incurred by industry, taxpayers, and consumers.
		The "no-control" scenario reflects expected conditions under the assumption that, absent the passage of the 1970 Clean Air Act, the scope, form, and stringency of air pollution control programs would have remained as they were in 1970.
		The direct benefits of the Clean Air Act from 1970 to 1990 include reduced incidence of a number of adverse human health effects, improvements in visibility, and avoided damage to agricultural crops.

		An independent study commissioned by the Foundation for Clean Air Progress found that America’s air is dramatically cleaner and healthier today than it was 30 years ago.
		Using the most recent EPA data available, experts have determined that four of the six most serious pollutants identified by the Clean Air Act of 1970 are no longer being released into the air at unhealthy levels.
		Clearly, these results are directly related to the Clean Air Act of 1970 and its subsequent amendments, combined with the vigilance of energy utilities, power generators, transportation companies and highway associations.

	The Environmental Literacy Council - Clean Air Act
		At the National level, most air quality regulations in the United States are promulgated and enforced by three federal agencies: the Environmental Protection Agency (EPA), the Occupational Health and Safety Administration (OHSA), and the Mining Safety and Health Administration.
		For a better understanding of the regulatory enforcement relationship between federal and state governments, see this explanation by the U.S. Although the first Clean Air Act was passed in 1963, the current national air pollution program is based on the 1970 version of the law.
		States and local governments that are not in compliance with EPA air quality standards may be forced to take costly measures to reduce pollutants, including imposing stricter standards for emissions from motor vehicles, requiring the use of alternative clean fuels, and placing additional controls on industries and business.

	NRDC Press Archive: Bush Administration to Gut Clean Air Act
		Under this scheme, all of the Clean Air Act violations the Justice Department is prosecuting at nine Tennessee Valley Authority power plants and those at a recently convicted Ohio Edison plant would have been allowed, according to NRDC.
		The upgrades at those plants increased air pollution by hundreds of thousands of tons, but because they cost less than 20 percent of the replacement value of the process units, TVA and Ohio Edison would not have had to install modern pollution controls under the new rule.
		The Clean Air Act's new source review provision was instituted in 1977 to reduce pollution from coal-fired power plants, oil refineries and other large industrial facilities.
