SALT LAKE CITY -- Gov. Gary Herbert has responded to recent protesters calling for solutions to Utah's bad air and says his office is taking the problem seriously.
Herbert said Tuesday that Utah's smog has been problem for a long time but there's no "silver bullet" to solve it.
He outlined steps the state has taken to reduce emissions from industrial polluters and says the state's single largest polluter, Kennecott Utah Copper, has reduced emissions significantly.
He noted that most of the pollution comes from cars, and repeated his call for everyone to do their part.
The governor also says his office has been discussing ways to get more people to take public transit with the Utah Transit Authority.
Last week, protesters delivered a petition to the governor asking for action on the smog.
