How many pounds of PCB must a spill exceed for notification to the appropriate EPA regional office?

When it comes to spills of Polychlorinated Biphenyls (PCBs), the Environmental Protection Agency (EPA) established a regulation that requires notification if the amount of PCBs spilled exceeds a specific threshold. This threshold is set at 10 pounds. The requirement for notification is essential for ensuring that appropriate response measures can be initiated to prevent environmental contamination and safeguard public health.

In this context, exceeding 10 pounds necessitates that the responsible parties notify the EPA regional office to ensure that they can manage the situation effectively and mitigate any potential harm. Understanding these regulations is critical for compliance and environmental safety, particularly for individuals managing hazardous materials. The other options reflect amounts that do not meet the regulatory standard for notification, thereby underscoring the importance of recognizing and adhering to the established threshold of 10 pounds for PCB spills.
