The United States Environmental Protection Agency has promulgated a rule to limit the production and consumption of certain chlorofluorocarbons and brominated compounds to reduce the risks of stratospheric ozone depletion as of August 1, 1988. The requirements have been proposed under section 157(b) of the Clean Air Act and constitute the U. S. implementation of the “Montreal Protocol on Substances That Deplete the Ozone Layer” which was signed by 24 countries, including the U. S., on September 16, 1987 in Montreal, Canada.
This paper will address the subject by delineating the events which have led to the final ruling. It will begin with a technical and regulatory background of chlorofluorocarbons. The original EPA proposal and comments by affected industries, especially the automotive industry, will then be presented. Other views will also be given including discussions of current legislation and the upcoming change in the administration. Concluding remarks will be made in light of the international environmental precedent set by the agreement in Montreal.
