Air Pollution Law: Air Quality Standards and Regulations

Lead is not a criteria pollutant under the Clean Air Act, but it is regulated as a hazardous air pollutant.

The primary NAAQS for PM2.5 is 12 µg/m³, averaged over a 24-hour period.

Residential heating is not a major source of air pollution in the United States, compared to the other options.

The PSD program is designed to prevent air quality from deteriorating in areas that meet NAAQS by requiring new or modified major sources to install the best available control technology.

Solar panels are not air pollution control devices, but they are used to generate electricity from sunlight.

Retrofitting is the process of reducing air pollution from existing sources by installing new or upgraded pollution control devices.

Carbon dioxide is not a HAP listed under the Clean Air Act, but it is a greenhouse gas that contributes to climate change.

The NSR program is designed to regulate air pollution from new or modified major sources by requiring them to obtain permits and install the best available control technology.

Weather stations are not air quality monitoring stations, but they can be used to collect data on meteorological conditions that can affect air quality.

Standard-setting is the process of establishing air quality standards by setting limits on the concentration of pollutants in the air.

Zoning regulations are not air pollution control strategies, but they can be used to control land use and development in a way that reduces air pollution.

The CAIR was designed to reduce air pollution from power plants in the eastern United States by setting limits on emissions of sulfur dioxide and nitrogen oxides.

Operating permits are not air pollution permits, but they are required for certain types of facilities to ensure that they are operating in compliance with air pollution regulations.

Enforcement is the process of enforcing air pollution laws and regulations by taking actions such as issuing fines, penalties, or injunctions.
