If a chemical spill is significant, who must be notified?

The National Response Center is the correct notification point for significant chemical spills due to its role as the federal communication center that coordinates the response to hazardous materials incidents. When a significant spill occurs, it is critical to promptly inform the National Response Center, as they provide a vital link between the incident and the appropriate federal and state resources needed for response and recovery. This ensures that the incident is properly documented, and emergencies are effectively managed, mitigating risks to public health and the environment.

In addition, while notifying local authorities and possibly other agencies like the Environmental Protection Agency might also be necessary depending on the specific circumstances or local regulations, the immediate responsibility typically lies with the National Response Center. This center handles the initial reports and coordinates efforts with regional and local agencies.
