If a hazardous material is spilled, carriers must file detailed reports with the National Response Center within how many days?

• A. 30
• B. 7
• C. 60
• D. 90

Answer: (A)

Hazardous material spills require a two-step reporting process: notify the National Response Center immediately by phone if required, and then file a detailed written follow-up within 30 days of discovery. The 30-day window is the deadline for the written report because it allows time to gather precise information—what was released, quantities, locations, actions taken, and potential environmental impact—while ensuring regulators receive timely, documented details. Other timeframes like 7, 60, or 90 days don’t match the regulatory requirement for the written follow-up, so the 30-day period is the correct deadline.
