444 U.S. 111 (1987)
EPA v. E.I.
What are the standards for the EPA to enforce hazardous substance regulations under CERCLA, particularly concerning the sufficiency of evidence for administrative orders?
Under CERCLA, the EPA can issue orders requiring responsible parties to clean up hazardous waste sites when it has a reasonable basis to believe that a release of hazardous substances may pose an imminent and substantial danger to public health or the environment.
The Supreme Court held that the EPA acted within its statutory authority under CERCLA, and its findings were to be accorded deference as long as they were reasonable and based on the evidence available at the time.
This case is crucial for law students to understand the deference courts afford to administrative agencies in executing their regulatory functions, particularly in environmental law. It illustrates the interplay between legislative intent and agency expertise, setting a precedent for interpreting regulatory statutes' scope and how agencies implement those statutes. It also highlights the evidentiary standards that underpin agency-led environmental enforcement actions.
