The U.S. Congress enacts the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund).
On December 11, 1980, President Jimmy Carter signs into law the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund. The act empowers the Environmental Protection Agency to identify and clean up hazardous waste sites nationwide. It establishes a trust fund, financed by taxes on chemical and petroleum industries, to finance emergency cleanup efforts. Superfund also grants federal authorities broad powers to compel responsible parties to perform cleanups or reimburse the government. This landmark legislation marks a turning point in U.S. environmental policy, prioritizing public health and ecosystem restoration.
