It was the final environmental permit needed for the $2 billion Plant Washington project to move ahead, The Macon Telegraph reports.
If built, the plant could become Georgia’s first new coal-fired power plant in more than a quarter century.
The air permit was revised this summer in response to a court order after the original permit was appealed by the environmental law firm Greenlaw.
The new version sets a tighter limit for fine particle pollution, which can cause heart and lung problems when breathed deep into the lungs. It also revised the method for limiting organic hazardous air pollutants. Both changes were modeled on proposed new federal rules, officials with the Georgia Environmental Protection Division have said.
