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.
