The Sierra Club is challenging a state decision giving an energy company extra time to install pollution controls at five coal-fired power plants. The Illinois Pollution Control Board agreed to give Texas-based Dynegy five more years to comply with state pollution standards.
Dynegy recently acquired the plants from Ameren Corp. That includes one in Bartonville. The Sierra Club filed an appeal in Illinois’ Fourth District Court last month. The group says pollution from the plant is causing significant air quality issues. A Dynegy spokeswoman says the variance is more stringent than one granted to Ameren.
