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. Wikipedia does not have an article with this exact name. ...

The role of the federal government and the role of the states
Although the 1990 Clean Air Act is a federal law covering the entire country, the states do much of the work to carry out the Act. For example, a state air pollution agency holds a hearing on a permit application by a power or chemical plant or fines a company for violating air pollution limits. A state of the United States (a U.S. state) is any one of the fifty states (four of which officially favor the term commonwealth) which, along with the District of Columbia, form the United States of America. ...

Under this law, the EPA sets limits on how much of a pollutant can be in the air anywhere in the United States. This ensures that all Americans have the same basic health and environmental protections. The law allows individual states to have stronger pollution controls, but states are not allowed to have weaker pollution controls than those set for the whole country. EPA redirects here. ...

The law recognizes that it makes sense for states to take the lead in carrying out the Clean Air Act, because pollution control problems often require special understanding of local industries, geography, housing patterns, etc.
States have to develop state implementation plans (SIPs) that explain how each state will do its job under the Clean Air Act. A state implementation plan is a collection of the regulations a state will use to clean up polluted areas. The states must involve the public, through hearings and opportunities to comment, in the development of each state implementation plan. The three letter abbreviation SIP can refer to the following: Computing/Engineering Session Initiation Protocol, an IETF standard Single in-line package for packaging components. ...
EPA must approve each SIP, and if a SIP isn't acceptable, EPA can take over enforcing the Clean Air Act in that state.
The United States government, through EPA, assists the states by providing scientific research, expert studies, engineering designs and money to support clean air programs. Research is often described as an active, diligent, and systematic process of inquiry aimed at discovering, interpreting and revising facts. ...
Engineering is the application of scientific and technical knowledge to solve human problems. ...
Interstate air pollution Air pollution often travels from its source in one state to another state. In many metropolitan areas, people live in one state and work or shop in another; air pollution from cars and trucks may spread throughout the interstate area. The 1990 Clean Air Act provides for interstate commissions on air pollution control, which are to develop regional strategies for cleaning up air pollution. The 1990 Clean Air Act includes other provisions to reduce interstate air pollution. A metropolitan area is a large population center consisting of a large city and its adjacent zone of influence, or of several neighboring cities or towns and adjoining areas, with one or more large cities serving as its hub or hubs. ...

International air pollution Air pollution moves across national borders. The 1990 law covers pollution that originates in Mexico and Canada and drifts into the United States and pollution from the United States that reaches Canada and Mexico.
