33. Clean air act (1970): federal law that regulates air emissions from area, stationary, and mobile sources
Clean water act (1970’s): established the basic structure for regulating discharges of pollutants into the waters of the United States. It gave EPA the authority to implement pollution control programs such as setting wastewater standards for industry.

34. 3. Comprehensive Environmental Response, Compensation, and Liability Act (Superfund ) (CERCLA): CERCLA (pronounced SIR-cla) provides a Federal “Superfund” to clean up uncontrolled or abandoned hazardous-waste sites as well as accidents, spills, and other emergency releases of pollutants and contaminants into the environment
*Governed by the EPA
