Which of the following refers to a party potentially liable under the Superfund law?

The correct choice identifies a party potentially liable under Superfund law, specifically anyone involved in the generation of hazardous waste. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), often referred to as Superfund, holds certain parties responsible for the cleanup of sites contaminated with hazardous substances. This includes individuals or companies that either generated the waste or were involved in transporting or disposing of it improperly.

In this context, a person who generated hazardous waste directly contributes to the environmental concern that Superfund laws address, making them potentially liable for cleanup costs and damages associated with contamination. This aligns tightly with the purpose of the Superfund law, which is to ensure that those who create pollution are responsible for managing its impacts on the environment and public health.

The other options do not reflect the liability structure set out by Superfund laws. Completing safety training, building residential homes, or managing financial assets does not implicate a person in the responsibility for hazardous waste or contamination issues that Superfund law aims to resolve.
