Rh. Schulze, THE 20-YEAR HISTORY OF THE EVOLUTION OF AIR-POLLUTION CONTROL LEGISLATION IN THE USA, Atmospheric environment. Part B, Urban atmosphere, 27(1), 1993, pp. 15-22
Over the past 20 years, the U.S. Congress has passed four acts relatin
g to clean air. The 1970 act set out a comprehensive plan for federal-
state partnership to require all areas in the country to meet National
Ambient Air Quality Standards. In 1977, the act was amended and expan
ded, both to address many of the problems encountered in the 1970 act
and to reorient the law to limit significantly emissions of any sort,
even if there were no currently identified health-related reasons. In
1986, the Emergency Planning and Community Right-to-know Act was passe
d, as an amendment to a solid waste law, in response to the desire to
prevent chemical release tragedies. After 10 years of effort, Congress
finally passed the 1990 Clean Air Act amendments which require a numb
er of new programs aimed at curbing urban ozone, rural acid rain, stra
tospheric ozone, toxic air pollutant emissions and vehicle emissions,
and establishing a new, uniform national permit system. This paper dis
cusses some of the consequences of the various acts and suggests ways
that others might learn from our 20 years of experience. Certain progr
ams have worked quite well, while some alternatives could have improve
d other programs.
