Under the federal Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA/Superfund), liability for hazardous waste cleanup can be imposed on:

AOnly the party who was the legal owner of the property at the time the contamination was originally deposited, since CERCLA tracks liability to the point of disposal

BCurrent owners, past owners, operators, and transporters of hazardous substances — even if they were not responsible for the contaminationCorrect

COnly parties who had actual knowledge of the hazardous waste at the time of acquisition, since innocent purchasers are protected by the bona fide prospective purchaser defense

DOnly the entity that held an EPA permit authorizing discharge at the site, since permitted discharges are exempt from CERCLA liability under the permit shield doctrine

Why Current owners, past owners, operators, and transporters of hazardous substances — even if they were not responsible for the contamination Is Correct

Answer B: Current owners, past owners, operators, and transporters of hazardous substances — even if they were not responsible for the contamination

CERCLA imposes strict, joint, and several liability on a broad class of potentially responsible parties (PRPs), including current and past owners, operators, generators, and transporters of hazardous substances — regardless of fault or knowledge at the time.

Exam Tip: Environmental

Environmental questions test knowledge of hazards like asbestos, lead-based paint, radon, and mold. Know the disclosure requirements and when a professional inspection is required. CERCLA liability is strict, joint, and several.
