The Environmental Protection Agency says it will release final rules on ozone pollution by this fall. Ozone is one of the main contributors to smog formation, mostly in urban areas.

South Dakota Senator Mike Rounds says he is concerned with the rules, and the cost to implement them…

 

A group advising the EPA suggests setting the ozone standard at sixty to seventy parts per billion. The current limit is seventy five parts per billion.

Rounds says the rules would force each state to come up with its own set of restrictions…

 

Rounds says if states don’t comply with the proposed rules, their highway funding could be at risk, and that could include South Dakota…

 

The rules could also severely limit the output of coal fired power plants.
