CERCLA
CERCLA is the Comprehensive Environmental Response, Compensation, and Liability Act, commonly called Superfund. It authorizes responses to releases or threatened releases of hazardous substances and imposes liability on certain responsible parties. The law affects contaminated site cleanup, cost recovery, contribution claims, and property transactions.
Who can face CERCLA liability?
Potentially responsible parties include current owners and operators, certain past owners and operators, parties that arranged for disposal or treatment of hazardous substances, and certain transporters. Liability can reach a current owner that did not cause the original contamination.
Depending on the circumstances, liability may be strict, retroactive, and joint and several. When harm cannot be divided, a party may face exposure beyond its own share of contamination. The statute has defenses and liability protections, but their requirements are technical and fact-dependent.
CERCLA is best known for sites on EPA’s National Priorities List. Its liability provisions can also affect contaminated property disputes outside listed Superfund sites. A site’s absence from that list does not establish that CERCLA is irrelevant.
A Phase I report does not guarantee liability protection
A buyer seeking innocent landowner, bona fide prospective purchaser, or contiguous property owner protection generally must meet pre-acquisition requirements and continuing obligations after purchase. A Phase I environmental site assessment often plays an important role, but it does not by itself establish eligibility.
The assessment’s scope and timing, the buyer’s own responsibilities, and required follow-up all matter. Determine whether the review is intended only to support a business decision or also to help preserve a statutory landowner protection. Use the due diligence checklist to organize questions; it does not establish a defense.
A private indemnity can allocate financial responsibility between parties, but it generally does not prevent EPA or a California agency from pursuing a legally responsible party. Review the strength and scope of an indemnity rather than treating it as immunity from regulatory liability.
Cleanup costs and multi-party disputes
CERCLA disputes may turn on contamination sources, migration, divisibility of harm, remedy selection, response costs, natural resource damages, or equitable allocation. Technical documentation and cost tracking are especially important when a party may seek cost recovery or contribution.
A groundwater plume can connect multiple properties and historical operators. Ownership records, operating history, disposal records, sampling, agency communications, and insurance policies may help establish who was involved and when. A preliminary environmental finding does not settle causation or liability.
Agreements should address who will perform cleanup, who will pay, access rights, applicable standards, deliverables, and future obligations. Settlements may also require careful attention to contribution protection, releases, covenants, and responsibility for later work.
Federal and California requirements can overlap
A California site may involve CERCLA alongside DTSC oversight, Regional Water Board requirements, hazardous waste regulation, and state-law claims. Coordinate these requirements rather than assuming one agency’s resolution disposes of every issue.
Distinguish CERCLA hazardous substances from petroleum-only releases and other conditions governed by different programs. Different legal frameworks can apply to the same property. For owners evaluating reuse, see brownfield redevelopment.

Questions about CERCLA
Can I be liable if I did not cause the contamination?
Yes. Current ownership or operation can create potential CERCLA liability even when another party caused the original release. Available defenses and landowner protections depend on the facts and compliance with their requirements.
Does a seller’s indemnity keep EPA from pursuing the buyer?
Generally, no. A private agreement may allocate costs between buyer and seller without eliminating either party’s liability to the government.
Does CERCLA apply only to listed Superfund sites?
No. Its liability provisions may affect contaminated property and cleanup disputes beyond sites on the National Priorities List.
