Natural resource damages (NRD) under federal law is a statutory cause of action to compensate for injury to natural resources resulting from releases of hazardous substances or oil. Designated officials are authorized under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Oil Pollution Act (OPA), among others, to act as “trustees” on behalf of the public or tribes.

The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) established the “Superfund,” which allows the U.S. Environmental Protection Agency (EPA) to clean up contaminated sites. It also forces the parties responsible for contamination to either perform cleanups or reimburse the government for the EPA-led cleanup work. The Superfund program relies on several tools to protect against lasting contamination.
