The _________ that was passed in 1970 limits the amount of certain pollutants that can be released into the air.

• A. Water Act
• B. Endangered Species Act
• C. Clean Air Act
• D. National Environmental Policy Act

Answer: (C)

Air pollution control is governed by a law that sets limits on what pollutants can be released into the atmosphere. Passed in 1970, the Clean Air Act is the framework that establishes these limits and directs the EPA to set National Ambient Air Quality Standards and regulate emissions from both industry and vehicles. This focus on reducing air contaminants like sulfur dioxide, particulates, nitrogen oxides, and lead is what distinguishes it from other environmental laws. In contrast, the Clean Water Act deals with water pollution, the Endangered Species Act protects threatened species, and the National Environmental Policy Act requires environmental impact assessments rather than pollutant limits.
