Under a proposed joint stipulation to modify a 2006 consent decree, a settling CAA defendant responsible for violations of PSD provisions and implementing regulations at coal-fired electric-generating stations in Alabama must pay a $100,000 civil penalty, must achieve reductions of sulfur dioxide and nitrogen oxides through the operation of emissions controls and unit retirements and conversions to natural gas, and must pay $1,500,000 to fund environmental mitigation projects to further reduce emissions and benefit communities in Alabama.
