What was authorized by the Clean Air Act of 1970 for hazardous air pollutants?

The Clean Air Act of 1970 was a landmark piece of legislation aimed at improving air quality across the United States. One of its significant provisions was the establishment of National Emission Standards for Hazardous Air Pollutants (NESHAP). This allowed the Environmental Protection Agency (EPA) to set and enforce standards to control the emissions of hazardous air pollutants known to cause serious health and environmental effects.

NESHAP aimed to protect public health and the environment by identifying hazardous air pollutants, which include certain metals, solvents, and other toxic chemicals. The EPA’s authority under this provision helps ensure that industries implement measures to limit the release of these harmful substances into the atmosphere, effectively reducing air pollution and its associated risks.

The other options relate to different aspects of environmental regulation but do not specifically connect to the Clean Air Act of 1970. Industrial waste disposal and water pollution regulation fall under other environmental statutes, while carbon footprint reduction incentives may be part of broader climate change initiatives but are not a direct result of the 1970 Clean Air Act.
