Which term describes a chemical that must be reported if released above the threshold report quantity?

• A. Hazardous Material
• B. Hazardous Waste
• C. Extremely Hazardous Substance
• D. Hazardous Chemical

Answer: (C)

The question tests understanding of reporting requirements under EPCRA. Only substances designated as extremely hazardous substances have a threshold reporting quantity that triggers mandatory reporting when a release exceeds that amount. These thresholds are set so communities and authorities can be alerted to significant chemical releases. Other terms like hazardous material, hazardous waste, or hazardous chemical describe broader categories and do not carry the specific TRQ-based reporting requirement. Therefore, the term that describes a chemical that must be reported if released above the threshold report quantity is extremely hazardous substance.
