Which federal law specifies the types of emergencies that must be reported to the NRC?

The correct answer identifies 49 CFR 191.3 as the federal regulation that outlines the types of emergencies that must be reported to the National Response Center (NRC). This regulation specifically sets the framework for what constitutes a reportable event, ensuring that incidents such as significant spills, leaks, and other hazards affecting public safety or the environment are promptly communicated.

Understanding this regulation is crucial for compliance purposes, as it delineates the specific scenarios and thresholds that necessitate immediate notification. This helps in establishing a coordinated response to ensure the safety of the public and the environment. Knowing the legal requirements ensures operators are prepared to act in accordance with federal directives, maintaining accountability and regulatory compliance.
