What is the purpose of SARA 302 in relation to Extremely Hazardous Substances (EHS)?

The selection of the purpose of SARA 302 as the reporting of Extremely Hazardous Substances (EHS) is based on the specific directives outlined in the Superfund Amendments and Reauthorization Act (SARA). SARA, particularly in its Section 302, specifically mandates facilities to report the presence and release of extremely hazardous substances to ensure public safety and the protection of the environment.

Under this provision, substances that qualify as "extremely hazardous" are identified based on their potential to pose significant risks in case of accidental releases. The reporting helps in making emergency response plans and informs local authorities and communities about potential hazards. This reporting obligation is crucial for minimizing risks associated with industrial activities involving these substances.

The other options relate to different facets of hazardous materials regulations but do not pertain specifically to the focus of SARA 302. For instance, while hazardous substances are addressed in a broader context, SARA 302 zeroes in on those deemed extremely hazardous. Similarly, determining flammability and establishing training requirements falls under other regulatory guidelines and not the specific reporting duties established by SARA 302. This focused approach is what solidifies option C as the correct understanding of SARA 302's role.
