Identifies actions to be taken by states and MPOs to reduce emissions from on-road mobile sources.

The original Clean Air Act was passed in 1963, but the national air pollution control program is actually based on the 1970 version of the law. The 1990 Clean Air Act Amendments are the most far-reaching revisions of the 1970 law. The 1990 amendments are often referred to as as the 1990 Clean Air Act.

The legislation, originally enacted in 1963, revised in 1970 and 1977, and amended in 1990, which is the basis for the national air pollution control program.

The primary federal law governing the regulation of emissions into the atmosphere. Originally passed in 1963, it has been amended several times with major changes occurring in 1970 and 1990.

gives EPA authority to set standards for air quality and to control the release of airborne chemicals from industries, power plants, and cars

long standing federal legislation that is the legal basis for the national clean air programs, last amended in 1990

Originally passed in 1963, although the 1970 version of the law is the basis of today's U.S. national air pollution program. The 1990 Clean Air Act Amendments are the most far-reaching revisions of the 1970 law, and are usually referred to as the 1990 Clean Air Act.

(CAA) The Superfund law incorporates those substances listed as hazardous air pollutants under section 112 of the Clean Air Act (CAA) as CERCLA hazardous substances, which is why the CAA is important to Superfund. In addition, Superfund cleanup responses must comply with CAA requirements. The CAA restricts the kinds and amounts of pollutants that may be released into the air and requires permits.

A law enacted by Congress to protect and enhance the quality of the nation's air resources, promote public health and welfare, and enhance the productive capacity of its population.

Enacted in 1970 and substantially amended in 1977 and 1990, the Clean Air Act is the longest and most complex of all US environmental statutes. It regulates everything from industrial plants and refineries (so-called “stationary sources”) to consumer products (ranging from paints to underarm deodorants) to engines and fuels. It also mandates programs designed to reduce acid rain, to protect the stratospheric ozone layer, and to control emissions of almost 200 compounds listed as hazardous air pollutants (HAPs).

In the U.S., the fundamental legislation to control air pollution. The original Clean Air Act was signed in 1963. The law set emissions standards for stationary sources, such as factories and power plants. Criteria pollutants included lead, ozone, CO, SO2, NOx and PM, as well as air toxics. The CAA was amended several times, most recently in 1990. The Amendments of 1970 introduced motor vehicle emission standards for automobiles and trucks.

An act of the U.S. legislature, passed in the early 1970s. The act was intended to address the growing problem of air pollution due to industrial operations.

Originally passed in 1963 and amended in 1970 to give the Environmental Protection Agency (EPA) the responsibility of setting air quality standards for each pollutant.

1963 Congressional act designed to protect air quality.

The original Clean Air Act was passed in 1963, but our national air pollution control program is actually based on the 1970 version of the law. It was revised in 1977 and 1990. It is the federal law regulating air emissions and has created numerous federal and state programs, procedures and standards designed to protect and enhance the quality of the nation’s air resources.

A federal law enacted to ensure that air quality standards are attained and maintained. Initially passed by Congress in 1963, it has been amended several times.

In 1990, Congress passed amendments to the Clean Air Act, which set minimum standards for air quality in America 's cities. Cities with excessive amounts of carbon monoxide and ozone must develop programs to battle air pollution.

Federal regulations which detail acceptable levels of airborne pollution and spell out the role of state and local governments in maintaining clean air.

Originally passed in 1955 and since amended in 1970, 1977 and 1990, it sets controls at the federal and state levels for air pollutants a.k.a. " the 800-pound gorilla."

The original Clean Air Act, signed into law by President Lyndon B. Johnson in 1963, was considered to be the first modern environmental law enacted by the United States Congress. However, it was the Clean Air Act of 1970, reviewed and amended by Congress in 1975, 1977, and 1990, that formed the basis of the currrent federal air pollution control program.

The original Clean Air Act was signed in 1963. The law set emissions standards for stationary sources (e.g., factories, power plants). The CAA was amended several times, most recently in 1990 (P.L. 101-549). The Amendments of 1970 introduced motor vehicle emission standards (e.g., automobiles, trucks). Criteria pollutants included lead, ozone, CO, SO2, NOx, and PM as well as air toxics.

See CAA

Set of laws passed in 1970 to regulate air pollution in the US. The goal of this act was to improve air quality, and it was revised in 1990 to be more detailed about issues such as the hole in the ozone layer and acid rain.

Public Law 84-159, established July 14, 1955, and amended numerous times since. The Clean Air Act: establishes Federal standards for air pollutants emitted from stationary and mobile sources; authorizes states, tribes and local agencies to regulate polluting emissions; requires those agencies to improve air quality in areas of the country which do not meet Federal standards; and to prevent significant deterioration in areas where air quality is cleaner than those standards. The Act also requires that all Federal activities (either direct or authorized) comply with applicable local, state, tribal and Federal air quality laws, statutes, regulations, standards and implementation plans. In addition, before these activities can take place in non-attainment or maintenance areas, the Federal agencies must conduct a Conformity Analysis (and possible Determination) demonstrating the proposed activity will comply with all applicable air quality requirements.

Clean Air Act was enacted to regulate/reduce air pollution. CAA is administered by the U.S. Environmental Protection Agency.

The Clean Air Act passed in 1970 and later in November of 1990 made into law established nationwide levels of acceptable air pollution from automobiles, individuals, and industry. The Environmental Protection Agency is responsible for enforcement of standards and regulations of the Clean Air Act. [Sell, J. Nancy.

The original Clean Air Act was passed in 1963, but our national air pollution control program is actually based on the 1970 version of the law. The 1990 Clean Air Act Amendments are the most far-reaching revisions of the 1970 law. In this summary, we refer to the 1990 amendments as the 1990 Clean Air Act.

A law that authorizes comprehensive control strategies that regulate sources of air emissions and establish ambient air quality standards. Regulations are published by EPA in 40 CFR 52-99.

A set of national standards for ambient air quality that defines the principal types and levels of pollution that should not be exceeded. This law requires states to develop "state implementation plans" for achieving the ambient air standards in each air quality control region in the state.

The Clean Air Act Extension of 1970 is a United States federal law that requires the Environmental Protection Agency (EPA) to develop and enforce regulations to protect the general public from exposure to airborne contaminants that are known to be hazardous to human health. This law is an amendment to the Clean Air Act originally passed in 1963.

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 Air Quality act in 1967, the Clean Air Act Extension in 1970, and Clean Air Act Amendments in 1977 and 1990. Numerous state governments and local governments have enacted similar legislation, either implementing federal programs or filling in locally important gaps in federal programs.

The 1990 Clean Air Act is a piece of U.S. legislation relating to the reduction of smog and atmospheric pollution. It follows the Clean Air Act in 1963, the Clean Air Act Amendment in 1966, the Clean Air Act Extension in 1970, and the Clean Air Act Amendments in 1977.
