Question

In the United States, which piece of federal legislation holds polluting companies and individuals financially accountable for environmental clean-up and restoration?

Answer

NRCS (National Resource Conservation Service) and EPA (Environmental Protection Agency) are federal agencies, not pieces of legislation. NEPA (National Environmental Policy Act) requires environmental assesments for proposed federal projects and RCRA (Resource Conservation and Recovery Act) classifies waste as solid or hazardous and sets regulations for storage and treatment of said waste. CERCLA (Comprehensive Environmental Response Compensation and Liability Act) establishes a superfund for heavily polluted areas and holds responsible firms financially accountable.

Question

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of 1980 established the Superfund for heavily polluted or contaminated sites. What is the source of revenue for Superfund cleanup projects?

Answer

Superfund is initially federally funded (by taxpayer revenue), but the EPA uses CERCLA to hold Potentially Responsible Parties (PRPs) financially accountable and recover the cost of cleanup that has so far been financed by the government.

Question

Which of the following is a situation in which he individual would NOT be held responsible for cost of cleanup under CERCLA?

Answer

CERCLA identifies a Potentially Responsible Party as an individual or firm that currently owns the site, owned the site at the time contamination occurred, arranged to have waste stored/disposed at the site, or transported the waste and contributed to arranging disposal at the contaminated site. Individuals who purchase land where pollutants are currently being released can be held accountable, even if they did not contribute to the pollution.

The employee of a polluting firm who did not directly arrange for or assist in the handling and disposal of waste cannot be held financially accountable for the resulting cleanup.
