Hancock v. Train
Argued January 13, 1976
Decided June 7, 1976
426 U.S. 167
Although § 118 of the Clean Air Act obligates federal installations discharging air pollutants to join with nonfederal facilities in complying with state "requirements respecting control and abatement of air pollution," obtaining a permit from a State with a federally approved implementation plan is not among such requirements. There cannot be found in § 118, either on its face or in relation to the Act as a whole, nor can there be derived from the legislative history of the Clean Air Amendments of 1970, any clear and unambiguous declaration by Congress that such federal installations may not operate without a state permit. Nor can congressional intention to submit federal activity to state control be implied from the claim that under the State's federally approved plan it is only through the permit system that compliance schedules and other requirements may be administratively enforced against federal installations. Pp. 178-199.
497 F.2d 1172, affirmed.
