The principal statute addressing air quality concerns, the Clean Air Act was first enacted in 1955, with major revisions in 1970, 1977, and 1990. The act [1] requires EPA to set health-based standards for ambient air quality; [2] sets deadlines for the achievement of those standards by state and local governments; [3] requires EPA to set national emission standards for large or ubiquitous sources of air pollution, including motor vehicles, power plants, and other industrial sources; [4] mandates emission controls for sources of 187 hazardous air pollutants; [5] establishes a cap-and-trade program to limit acid rain; [6] requires the prevention of significant deterioration of air quality in areas with clean air; [7] requires a program to restore visibility impaired by regional haze in national parks and wilderness areas; and [8] implements the Montreal Protocol to phase out most ozone-depleting chemicals. This report describes the act's major provisions and provides tables listing all major amendments, with the year of enactment and Public Law number, and cross-referencing sections of the act with the major U.S. Code sections of the codified statute."
