On April 22, the Environmental Protection Agency (EPA) announced it reached a deal with Wisconsin Power and Light Co., Wisconsin Public Service Corp., Madison Gas and Electric Co., and Wisconsin Electric Power Co. on three coal-fired power plants in Wisconsin. The plants were alleged to be in violation of the Clean Air Act. The four companies must spend $8.5 million on environmental mitigation projects and $2.45 million in penalties; Wisconsin Power and Light Co. must invest $1 billion in pollution controls at the three plants. The environmental mitigation projects include funding for land acquisition, for long-term renewable energy purchase agreements, and for the U.S. Forest Service and National Parks Service to conduct damage analysis. The U.S. District Court for the Western District of Wisconsin will review the settlement, will oversee the 30 day public comment period, and will release a final ruling on the settlement.
