The Superfund program is administered by the Environmental Protection Agency (the “EPA”), and is designed to facilitate the clean up and investigation of areas contaminated with hazardous substances and/or pollution.
The goal of the program is to shift the burden of cleaning up sites from the taxpayer to the responsible person, entity, or entities. The 2021 Inflation Reduction Act (the “IRA”) brought in an excise tax on chemical manufacturers, aimed at funding the EPA to clean up, mitigate, and remediate contamination, spills, pollution, and other releases of hazardous substances/materials. This is a hypothecated tax, meaning the funds gathered through the tax are unable to be used by the government for any other purpose. This pot of money funds roughly 30% of clean up and remediation costs, with the remaining 70% funded by the responsible entity/person (Potentially Responsible Parties (“PRPs”)), under the “polluter pays” principle.
Superfund sites are identified and investigated by the EPA and state agencies based on a Hazard Ranking System (“HRS”). The higher the score out of 100, the more urgent the clean-up and remediation operation is. Once a Superfund site is identified (by scoring above a 28.5 on the HRS scale), it is placed on the National Priorities List (“NPL”), and designated for long term cleanup. A list of the NPLs by state can be found here.
Superfund sites are categorised as either “remedial” or “removal” sites:
- Superfund sites designated as “remedial” are those placed on the NPL, and are the less urgent of the two categories. An example of a remedial site would be a landfill containing hazardous materials, or a disused and/or abandoned chemical manufacturing plant, which while not posing an immediate risk to human health or the environment, has the potential to be highly damaging in the future.
- Superfund sites designated as “removal” are sudden environmental urgencies that require immediate action. Examples include oil spills, chemical fires, leaks of poisonous and/or toxic chemicals into water supplies, and other emergencies. In these cases, the EPA and state authorities will act urgently, as well as requiring the responsible party to take all possible mitigation measures as a matter of urgency, and seek compensation from the entities responsible at a later date.

Enforcement and penalties
The principal penalty under the Superfund Act is the polluter pays principle, where the PRPs are identified and required to pay a proportion of the costs of the cleanup/remediation. Identification of the PRPs can often be difficult, and in some cases impossible, especially in case where there are multiple PRPs, some historic (such as the builder of a chemicals plant that was sold to a number of different owners, who then sold the plant on themselves. Where the PRPs cannot be identified wholly or in part, the funds from the hypothecated excise tax are intended to allow the EPA/state agencies to pay the difference. PRPs fall into four categories:
- the current owner(s)/operator(s) of the site;
- previous owners/operator(s) of the site;
- anyone arranging for the disposal/treatment/dumping of hazardous materials at a site; and
- anyone responsible for transporting hazardous materials to the site.
Penalties can also include punitive fines and damages for failures to address the issues created; these can be especially severe in cases of egregious failures responding to removal sites, such as a “treble damages” penalty, imposed as a result of violation a “Superfund Unilateral Order”, which is a court order obtained by the EPA requiring parties to take an urgent and satisfactory response action.

Future
As with a number of environmental laws and regulations in the US, the future of the Superfund legislation is unclear, with the current administration signalling its desire to repeal the legislation, regarded as detrimental to fossil fuel companies’ interests.
