Georgia is the latest state that is saying that a new power-plant emission rule would have severe impact on the economy for consumers and businesses in the state, thus they are suing the EPA to block the rule. Georgia is one of 27 states that the rule requires to cap and regulate two major pollutants that come from coal-fired power plants: sulfur dioxides and nitrogen oxides.

The first deadline is Jan. 1. Georgia Power got 67 percent of its electricity from coal in 2010.

To comply, the utility would have to install pollution-control technology on its coal plants or buy emission allowances from other states. The end result would be consumers paying more in their monthly bill, but first Georgia Power must seek state regulators` approval.

Among the other states suing are Alabama, Florida and South Carolina.
