After discovery of an unintentional release of a reportable-quantity hazardous substance, when must the required detailed DOT incident report be submitted?
Correct answer: D – Within 30 days
Federal hazardous-materials rules require the person who had physical possession of the material to submit the detailed incident report within 30 days after discovering a reportable incident. The report is made on DOT Form F 5800.1. This written-report deadline does not replace any immediate notification that may also be required for the incident.
