What action does SARA take in relation to CERCLA?

The correct response indicates that SARA, the Superfund Amendments and Reauthorization Act, amended CERCLA, which stands for the Comprehensive Environmental Response, Compensation, and Liability Act.

SARA was enacted in 1986 to reauthorize and amend the original CERCLA legislation established in 1980. One of the key aspects of SARA was to address some of the limitations and shortcomings found in CERCLA. It introduced more stringent regulations regarding the identification and management of hazardous waste sites, improved community involvement in the cleanup process, and provided specific funding for the cleanup efforts termed as "Superfund."

Additionally, SARA emphasized the need for more technical assistance and established guidelines for the selection of cleanup methods, making the program more effective in dealing with hazardous waste. Therefore, understanding that SARA serves to amend CERCLA highlights its role in improving environmental protection and response initiatives, rather than repealing, enforcing, or merely increasing penalties related to CERCLA.
