Indiana lawmakers say the tougher federal standards on smog-forming pollution will harm the state's economy.
The Senate Environmental Affairs Committee advanced a resolution Tuesday that condemns the tougher ozone limits set by the U.S. Environmental Protection Agency.
The resolution comes just weeks after Gov. Mike Pence and 10 other governors sent a letter to the EPA urging it to keep the nation's current limits set in 2008.
Supporters of the resolution say the EPA is proposing a standard that would leave many counties unable to meet the new limits, stunting economic growth.
Critics say ground-level ozone causes smog that can lead to serious respiratory illness, particularly for children, elderly people and those with lung disease. They say good health is more important than job growth.
