inspections were passed. It was not until 1947 that California authorized the creation of Air Pollution Control Districts in every county of the state. Amendments to the Air Pollution Control Act of 1955 There have been several amendments made to The Air Pollution Act of 1955. The first amendment came in 1960, which extended research funding for four years. The next amendment came in 1962 and basically enforced the principle provisions of the original act. In addition, this amendment also called for research to be done by the Surgeon General. 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. The 1970 amendments, also known as the Clean Air Act, completely rewrote the 1967 act. In particular, the 1970 amendments required the newly created The United States Environmental Protection Agency to set technology-based National Ambient Air Quality Standards for major new stationary sources and state air quality management programs to protect public health and welfare. In addition, the 1970 amendments required various states to submit state implementation plans for attaining and maintaining the National Ambient Air Quality Standards and required the use of air monitoring to determine if implementation plans were successful. National technology-forcing emissions standards were also set for new automobiles. This amendment allowed citizens the ability to sue polluters or government agencies for failure to abide by the act. Finally, the amendment required that by 1975, the entire United States would attain clean air status. 1990 was the most recent amendments to the act under President George H. W. Bush. The 1990
