The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, is a significant federal law in the United States aimed at cleaning up sites contaminated with hazardous substances. Enacted by Congress on December 11, 1980, CERCLA gives the federal government authority to respond directly to releases or threatened releases of hazardous substances that may endanger public health or the environment.
Historical Context
The enactment of CERCLA was prompted by several high-profile environmental disasters in the 1970s, most notably the Love Canal disaster in New York, where toxic chemicals were improperly disposed of, leading to serious health issues for nearby residents. The mounting public concern over environmental pollution and the evident need for federal involvement in cleaning up hazardous waste sites catalyzed the creation of CERCLA.
Key Components and Provisions
Funding Mechanism
CERCLA established a trust fund, known as the Superfund, to finance cleanup activities. Initially funded by a tax on the chemical and petroleum industries, the Superfund now relies primarily on general tax revenues.
Liability and Enforcement
CERCLA holds responsible parties—such as current and former site owners, operators, transporters, and waste generators—liable for the costs of cleanup. This liability is strict, joint, and several, meaning that any one party can be held responsible for the entire cost.
National Priorities List (NPL)
The EPA uses the National Priorities List (NPL) to identify sites that warrant further investigation and long-term remediation. Sites on the NPL are prioritized based on the severity of contamination and the risk they pose to human health and the environment.
CERCLA Cleanup Process
The CERCLA cleanup process includes the following major steps:
1. Preliminary Assessment/Site Inspection (PA/SI)
EPA conducts a preliminary assessment and site inspection to determine if a site poses a significant risk.
2. National Priorities List (NPL) Listing
If significant risks are identified, the site is placed on the NPL.
3. Remedial Investigation/Feasibility Study (RI/FS)
A detailed investigation (RI) and analysis of potential cleanup methods (FS) are conducted.
4. Record of Decision (ROD)
The EPA issues a Record of Decision that outlines the selected cleanup plan.
5. Remedial Design/Remedial Action (RD/RA)
The detailed design of the cleanup plan (RD) is completed and implemented (RA).
6. Long-Term Monitoring and Maintenance
Post-cleanup, the site undergoes long-term monitoring and maintenance to ensure the effectiveness of the remediation.

Importance and Applicability
CERCLA plays a crucial role in safeguarding public health and the environment by:
- Ensuring hazardous waste sites are identified and cleaned up.
- Holding polluters accountable for contamination.
- Protecting communities from exposure to toxic substances.
Examples and Case Studies
- Love Canal, New York: The site that largely inspired the creation of CERCLA, where improper disposal of chemical waste led to severe health consequences for residents.
- Times Beach, Missouri: Contaminated with dioxin, leading to a federal buyout and extensive cleanup under CERCLA.
Considerations and Criticisms
Considerations
- The complexity and cost of site remediation.
- Legal and financial liabilities for potentially responsible parties (PRPs).
Criticisms
- Lengthy and bureaucratic cleanup process.
- Reliance on general tax revenue after the expiration of the original tax on chemical and petroleum industries.
Related Terms
- EPA (Environmental Protection Agency): The federal agency responsible for implementing CERCLA.
- NPL (National Priorities List): A list of sites designated for long-term remedial action under CERCLA.
- RCRA (Resource Conservation and Recovery Act): Another key environmental law that regulates the management of hazardous waste but focuses on ongoing waste management rather than site cleanup.
Comparisons
- CERCLA vs. RCRA: While both aim to protect the environment from hazardous waste, CERCLA focuses on cleaning up contaminated sites, whereas RCRA governs the ongoing management and disposal of hazardous waste.
Interesting Facts
- Brownfields: Under CERCLA, sites that have been cleaned up can be redeveloped and reused, turning “brownfields” into productive land again.

Summary
CERCLA, or the Superfund, is a cornerstone environmental law in the U.S., dedicated to addressing the cleanup of hazardous waste sites. Enacted in response to environmental disasters like Love Canal, CERCLA empowers the EPA to identify, investigate, and clean up contaminated sites, ensuring that responsible parties bear the cost of remediation. Despite its complexities and criticisms, CERCLA remains vital for protecting human health and the environment from the dangers of hazardous substances.
