What is the role of the Environmental Protection Agency (EPA) regarding air quality?

The Environmental Protection Agency (EPA) is primarily responsible for enforcing air quality standards to protect human health and the environment. The agency sets limits on the amount of specific pollutants that can be present in the air, based on scientific research regarding their effects on health and the environment. These standards ensure that air quality is maintained at a level that is safe for the general public.

By monitoring air quality and holding industries accountable for their emissions, the EPA plays a crucial role in reducing air pollution from various sources, such as vehicles, factories, and power plants. This regulatory framework is necessary to address issues like smog, acid rain, and respiratory problems caused by poor air quality. Through this enforcement, the EPA helps to maintain clean air standards, supporting overall public health and environmental sustainability.
