What year did the Comprehensive Environmental Response, Compensation and Liability Act get passed?

The Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) was enacted in 1980. This landmark legislation was established to address the cleanup of hazardous waste sites and to provide a framework for the federal government's response to environmental emergencies. The law allows the government to clean up sites contaminated with hazardous substances and to hold responsible parties liable for the costs of cleanup.

In this context, the other years listed in the choices are significant in environmental legislation and policy development, but they do not pertain to the establishment of CERCLA. For instance, 1970 marks the creation of the Environmental Protection Agency (EPA) and the passing of other significant environmental laws, while 1990 and 1985 refer to the amendments and development of further environmental policies, but none correlate directly with the introduction of CERCLA itself. Thus, 1980 is the pivotal year that introduced comprehensive measures for responding to hazardous waste challenges in the United States.
