Notifications and reporting for releases are based on which two factors?

• A. Type and rate
• B. Location and time
• C. Materials and quantities
• D. Cause and effect

Answer: (C)

Notifications and reporting for releases hinge on the material involved and the amount released. Regulations set a reportable quantity for each hazardous substance, so when a release crosses that threshold for a given chemical, authorities must be notified and, in some cases, the public is informed. This structure ensures that very hazardous substances or large releases trigger appropriate alerts regardless of where or when the release occurs. The timing and method of notification can vary with location or incident specifics, but the trigger itself is determined by which chemical is involved and how much of it was released.
