WASHINGTON — The Obama administration is proposing new rules to tighten restrictions on pollution from coal-burning power plants in the eastern half of the country, a key step to cut emissions that cause smog.
The Environmental Protection Agency said the new rules would cut sulfur dioxide emissions by 71 percent from 2005 levels by 2014 and nitrogen oxide emissions by 52 percent in the same time frame.
The regulation, known as the Clean Air Interstate Rule, requires 31 states from Massachusetts to Texas to reduce emissions that cause smog and soot and can travel long distances in the wind. The agency predicted the rule would prevent about 14,000 to 36,000 premature deaths a year.
The rule would overturn and toughen rules issued during the administration of former President George W. Bush.
