In 1967, the Air Quality Act of 1967 was passed. In 1967, the Air Quality Act was enacted in order to expand federal government activities. In accordance with this law, enforcement proceedings were initiated in areas subject to interstate air pollution transport. This amendment allowed states to enact federal automobile emissions standards. Senator Edmond Muskie (D-Maine) said that this was the “first comprehensive federal air pollution control.” The National Air Pollution Control Administration then provided technical information to the states, which the states used to develop air quality standards. The NAPCA then had the power to veto any of the states' proposed emission standards. This amendment was not as effective as it was initially thought to be, with only 36 air regions designated, and as well as no states having fully developed pollution control programs. In 1969, another amendment was made to the act. This amendment further expanded the research on low emissions, fuels, and automobiles.
