What term describes a potential polluter who may be held liable under CERCLA for contamination?

The term that describes a potential polluter who may be held liable under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is "PRP," which stands for Potentially Responsible Party. PRPs can include individuals or companies that have contributed to the contamination of a site, whether it be through the disposal of hazardous substances or other means.

Under CERCLA, the U.S. Environmental Protection Agency (EPA) has the authority to identify PRPs and hold them responsible for the cleanup of contaminated sites. This liability can arise even if the party did not directly cause the contamination but played a role in the activities that led to the release of hazardous substances.

Understanding the concept of potentially responsible parties under CERCLA is crucial for comprehending how environmental liability is determined and the measures that can be taken to address contamination issues. The other terms listed do not pertain to this specific legal context or liability framework outlined by CERCLA.
