Environmental Law
Superfund is the common name for the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), a U.S. federal law enacted in 1980 to address abandoned hazardous waste sites. It established a trust fund financed by taxes on chemical and petroleum industries, and it grants the Environmental Protection Agency (EPA) authority to compel responsible parties to clean up contaminated sites or to undertake cleanup itself and recover costs. The program has overseen the remediation of thousands of sites, but it has faced criticism for slow progress and funding shortfalls.
The Superfund program emerged from the discovery of severe contamination at Love Canal, New York, and other sites in the late 1970s, which galvanized public concern and prompted Congress to act. CERCLA was signed by President Jimmy Carter on December 11, 1980, creating a comprehensive liability scheme that holds potentially responsible parties (PRPs) strictly, jointly, and severally liable for cleanup costs. The law also established a $1.6 billion trust fund financed by excise taxes on crude oil and certain chemicals, though those taxes lapsed in 1995 and were reinstated by the Bipartisan Budget Act of 2015. The EPA administers the program, with authority to conduct removals, remedial actions, and enforcement, and it maintains the National Priorities List (NPL) to prioritize the most hazardous sites.
The cleanup process begins with site discovery and preliminary assessment, followed by a remedial investigation and feasibility study to evaluate risks and alternatives. The EPA then selects a remedy and implements it, often through a consent decree or unilateral order. Liability under CERCLA is retroactive, strict, and joint and several, meaning any PRP—including current and former owners, generators, and transporters—can be held responsible for the entire cost of cleanup. This has led to extensive litigation and the development of allocation mechanisms, such as de minimis settlements and contribution actions. The Superfund program also includes provisions for natural resource damages and for protecting the public from imminent threats through emergency removal actions.
Since its inception, Superfund has overseen the completion of cleanup at over 400 sites and has reduced risks at thousands more, but the program has faced persistent challenges. Funding has fluctuated, and the trust fund was nearly depleted by the early 2000s, leading to a reliance on appropriations and PRP-funded cleanups. The pace of remediation has been criticized for being slow, with some sites languishing on the NPL for decades. In 2021, the Infrastructure Investment and Jobs Act provided an additional $3.5 billion to the program, and the reinstated taxes have begun to replenish the trust fund. Environmental justice concerns have also emerged, as many Superfund sites are located in low-income and minority communities, prompting the EPA to integrate equity considerations into its decision-making.
Beyond the well-known NPL, Superfund includes a separate emergency response program for oil spills and hazardous substance releases, which operates under the National Contingency Plan. The program also addresses federal facilities, such as military bases and Department of Energy sites, which are cleaned up under interagency agreements. A notable edge case is the 'bona fide prospective purchaser' defense, which protects buyers who acquire contaminated property after conducting all appropriate inquiries, encouraging redevelopment. The EPA maintains a public database, the Superfund Enterprise Management System (SEMS), which allows citizens to track site status. Additionally, the program has inspired similar legislation in other countries, such as Japan's 2003 Soil Contamination Countermeasures Law, and has been a model for the European Union's Environmental Liability Directive.
