Extremely Hazardous Substances are the chemicals designated by EPA under EPCRA as requiring extra planning and reporting because releases could cause serious harm. This term is the EPA’s specific label for HazMat that triggers emergency planning, notifications to authorities, and community right-to-know requirements when quantities exceed certain regulatory thresholds. That focus on regulatory designation and planning is why it’s the correct term in this context.

The other ideas don’t fit the EPA’s labeling: Hazardous Materials Incident is a general description of an event, not the EPA designation; SARA Title III is the law that establishes those reporting requirements, not the EPA term for HazMat itself; NFPA 472 is a training standard, not a term used by EPA to label HazMat.
