What did the original Clean Air Act specifically target?
It set targets for reducing the emissions of hydrocarbons and nitrogen oxides by vehicles and assembly plants. It also required new automobiles to meet stricter pollution standards, whether by installing pollution control equipment like catalytic converters or by burning cleaner fuels.
What are the main components of the Clean Air Act?
The act establishes federal standards for mobile sources of air pollution and their fuels and for sources of 187 hazardous air pollutants, and it establishes a cap-and-trade program for the emissions that cause acid rain. It establishes a comprehensive permit system for all major sources of air pollution.
What are the 6 primary pollutants that come from burning coal?
