MidAmerican Energy Co. has agreed to stop burning coal in seven power plant boilers in Iowa and limit emissions from two others as part of a settlement with an environmental group.
The Sierra Club filed a lawsuit last year claiming MidAmerican was violating the Clean Air Act by emitting more pollution than allowed in permits in the Port Neal plant near Salix, as well as plants in Bettendorf, and Council Bluffs.
To settle the case, MidAmerican agrees to stop burning coal in boilers at Port Neal and Council Bluffs by April 2016.
The company says it also will stop burning coal in Bettendorf but will operate the facility with natural gas.
Installation of a cleaning system is under way at other boilers at Port Neal.
MidAmerican says it settled the case Tuesday to avoid costs to customers.
