Abstract
Some of you would have me discuss today the present politics of clean air, some of you would have me discuss in detail the pending amendments to the Clean Air Act, some would have me discuss the failings and failures of the Clean Air Act. I am going to discuss each of these subjects. I want today to put the Clean Air Act and especially it’s 1976 amendments into context. That context is political, it involves the pending amendments and it involves more than 5 years of experience and administrative and judicial interpretation.
