Obama administration issues new ozone rules
The U.S. government set a new ozone standard Thursday, tightening limits on the smog-forming pollution linked to asthma and respiratory illness.
The U.S. Environmental Protection Agency said the new standard of 70 parts per billion will reduce exposure to dangerous ozone pollution and prevent thousands of asthma attacks, emergency room visits and even premature deaths.
The new standard is below the current standard of 75 parts per billion but at the high end of a range announced by the EPA last fall.
The move fulfills a long-delayed campaign promise by President Barack Obama, but sets up a fresh confrontation with opposition lawmakers already angry about the administration’s plans to curb carbon pollution from coal-fired power plants and regulate small streams and wetlands.
Business groups said a new ozone standard is unnecessary and could jeopardize jobs.
Environmental and public health groups also were unhappy. They said the new standard was a step in the right direction but did not go far enough.
EPA Administrator Gina McCarthy said her job is to set science- backed standards that protect the health of people.
“Put simply, ozone pollution means it hurts to breathe for those most vulnerable: our kids, our elderly and those suffering from heart and lung ailments,” McCarthy said. “Today’s action is one of the most important measures we can take for improving public health, reducing the costs of illness and protecting our children’s health.”
Harold Wimmer, president and chief executive of the American Lung Association, said the new standard “simply does not reflect what the science shows is necessary to truly protect public health.”
