Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA)
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), commonly known as Superfund, is a United States federal law enacted in 1980. It was created to address abandoned hazardous waste sites and ensure their cleanup, protecting public health and the environment from contamination.
Key Components:
-
Identification and Cleanup of Hazardous Sites: CERCLA provides a federal “Superfund” to clean up uncontrolled or abandoned hazardous waste sites as well as accidents, spills, and other emergency releases of pollutants and contaminants into the environment.
-
Enforcement of Liability: The Act holds liable potentially responsible parties (PRPs), including current owners and operators, past owners and operators at the time of disposal, waste generators, and transporters.
-
Response Actions: There are two primary response actions:
- Removal Actions: Short-term removals addressing immediate threats.
- Remedial Actions: Long-term actions providing permanent solutions.
Examples:
- Love Canal: A notorious CERCLA case where hazardous waste disposal led to severe health and environmental issues, spurring the law’s passage.
- Times Beach, Missouri: Cleanup and relocation efforts following contamination from dioxin-tainted oil used to control dust.
Frequently Asked Questions (FAQs):
Q1: What is a Superfund site?
A: A Superfund site is any land in the United States that has been contaminated by hazardous waste and identified by the Environmental Protection Agency (EPA) as a candidate for cleanup because it poses a risk to human health or the environment.
Q2: Who pays for the cleanup of a Superfund site?
A: Primarily, responsible parties are held liable for cleanup costs. If responsible parties cannot be found or are unable to pay, the Superfund trust fund may be used to pay for the cleanup.
Q3: How does the EPA prioritize sites for cleanup?
A: The EPA uses the Hazard Ranking System (HRS) to assess the potential threat to public health and the environment and prioritize sites on the National Priorities List (NPL).
- Environmental Protection Agency (EPA): The federal agency responsible for managing and implementing U.S. environmental laws.
- National Priorities List (NPL): A list of sites in the U.S. identified as priorities for cleanup under CERCLA.
- Potentially Responsible Party (PRP): Individuals or organizations potentially responsible for contamination.

Fundamentals of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA): Environmental Law Basics Quiz
### What is the main objective of CERCLA?
- [x] To clean up hazardous waste sites and hold responsible parties accountable.
- [ ] To regulate emissions from industrial facilities.
- [ ] To manage natural parks.
- [ ] To oversee wildlife protection.
> **Explanation:** The primary objective of CERCLA is to clean up sites contaminated with hazardous substances and hold the responsible parties accountable for the cleanup.
### Which federal agency is primarily responsible for enforcing CERCLA?
- [x] Environmental Protection Agency (EPA)
- [ ] Food and Drug Administration (FDA)
- [ ] Occupational Safety and Health Administration (OSHA)
- [ ] National Aeronautics and Space Administration (NASA)
> **Explanation:** The Environmental Protection Agency (EPA) is primarily responsible for enforcing the provisions of CERCLA.
### Who can be held liable for contamination under CERCLA?
- [x] Current property owners, past property owners, waste generators, and transporters.
- [ ] Only the current property owners.
- [ ] Only the federal government.
- [ ] Only the transporters.
> **Explanation:** CERCLA imposes liability on various parties, including current property owners, past property owners at the time of disposal, waste generators, and transporters who may have contributed to site contamination.
### What is the National Priorities List (NPL)?
- [x] A list of contaminated sites that represent the most significant threat to public health and the environment.
- [ ] A list of industrial facilities monitoring air quality.
- [ ] A list of federal parks needing maintenance.
- [ ] A list of endangered species.
> **Explanation:** The National Priorities List (NPL) includes sites that the EPA has identified as priorities for long-term remedial action because they pose significant threats to public health and the environment.
### How does the EPA determine which sites to prioritize on the National Priorities List?
- [ ] Through public voting.
- [ ] By order of population nearby.
- [ ] By financial contribution of the site owner.
- [x] Using the Hazard Ranking System (HRS) to assess the threat.
> **Explanation:** The EPA uses the Hazard Ranking System (HRS) to assess the threat a site poses to public health and the environment, and this determines its priority level on the National Priorities List.
### If responsible parties cannot be found or are unable to pay for cleanup, what is used to cover the costs?
- [ ] State funds.
- [ ] Federal loans.
- [ ] Charity donations.
- [x] The Superfund trust fund.
> **Explanation:** The Superfund trust fund is used to pay for the cleanup costs in cases where no responsible parties can be found or they are unable to pay.
### What were the two types of response actions established under CERCLA?
- [ ] Short-term responses and public hearings.
- [x] Removal actions and remedial actions.
- [ ] Monitoring and assessment.
- [ ] Legal actions and fines.
> **Explanation:** CERCLA established two types of response actions: removal actions (short-term) to address immediate threats, and remedial actions (long-term) to provide permanent solutions.

- [ ] The Clean Water Act of 1972.
- [x] The Love Canal disaster.
- [ ] The invention of plastic.
> **Explanation:** The Love Canal disaster, where hazardous waste led to severe health and environmental issues, greatly spurred the enactment of CERCLA.
### What role does the "Potentially Responsible Party" (PRP) play in CERCLA cleanups?
- [ ] They solely pay fines.
- [ ] They only monitor the sites.
- [x] They are liable for contamination and cleanup costs.
- [ ] They issue cleanup permits.
> **Explanation:** Potentially Responsible Parties (PRPs) are individuals or organizations that may be held liable for contamination and bear the responsibility for cleanup costs.
### Which of the following best describes a Superfund site?
- [ ] An agricultural field with healthy crops.
- [x] A contaminated site in need of cleanup under CERCLA.
- [ ] A national park.
- [ ] An urban development zone.
> **Explanation:** A Superfund site refers to a contaminated area identified by the EPA where hazardous substances are located and require cleanup efforts under CERCLA.
