Which of the following statements best describes SARA's purpose?

The Superfund Amendments and Reauthorization Act (SARA) primarily focuses on ensuring that the public is informed about hazardous substances that may pose risks to health or the environment. One of its key provisions is the requirement for facilities that handle hazardous substances to report on releases of those substances, enhancing transparency and allowing communities to understand potential exposure to toxic materials. This reporting mechanism is designed to empower citizens and ensure that they are aware of any threats in their vicinity, thus promoting public safety and environmental protection.

While other options touch on important environmental regulatory areas, they do not encapsulate the core purpose of SARA as effectively as the focus on hazardous substance release reporting does. The act's emphasis on public disclosure and community awareness is a critical element that distinguishes it from other regulatory initiatives, which may focus more specifically on aspects such as air quality or waste management without the same level of public information engagement.
