The answer identifies the Hazardous Transportation Act as not being considered an active environmental, health, or safety law in the context provided. This option is correct because, while the other laws listed focus on regulating environmental impacts, pollution control, and public health associated with air quality, water safety, and environmental assessments, the Hazardous Transportation Act has historically not been regarded as a primary piece of legislation for ongoing environmental and health safety regulations.

The Clean Air Act, for example, is an active law that governs air emissions from stationary and mobile sources, ensuring air quality standards to protect public health and the environment. The National Environmental Policy Act establishes a framework for environmental planning and decision-making, emphasizing the necessity of assessing environmental impacts before major federal actions. The Safe Drinking Water Act sets standards to protect drinking water quality and mandates regular monitoring to ensure safety and compliance for public health.

In contrast, the Hazardous Transportation Act focuses on the safe transport of hazardous materials but does not have the same active legislative status or broad application as the other acts regarding continuous environmental health and safety regulation. Therefore, its designation as not being an active law aligns with the context of the question.
