Which agency defines the small spill threshold used in the ERG?

• A. EPA
• B. OSHA
• C. DOT
• D. NTSB

Answer: (C)

The key idea is that the small spill threshold in the ERG comes from the Department of Transportation because the ERG is a field guide designed for hazardous materials incidents during transport and is tied to the hazmat rules DOT regulates. DOT determines what counts as a “small spill” for initial response purposes, so responders can quickly decide the level of action required. The EPA, OSHA, and NTSB have different roles—environmental protection, workplace safety, and accident investigation, respectively—and do not define this transport-related threshold.
