Death and disease attributable to fine particle pollution from Hennepin
In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants. Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.

Illinois Power Company and Dynegy Midwest Generation
On March 7, 2005 the U.S. Department of Justice and the U.S. EPA along with the State of Illinois announced a settlement between Illinois Power Company and its sucesscor, Dynegy, addressing alleged violations of New Source Review provisions of the Clean Air Act at company's Baldwin Energy Station. The EPA noted that sulfur dioxide (SO2) and nitrogen oxide (NOx) emissions at the plant will decrease by 54,000 tons each year through the installation of approximately $500 million worth of new pollution control equipment. In addition to the Baldwin Generating Station, the Havana Power Station, Hennepin Power Station and Vermilion Power Station, Wood River Station were involved in the settlement.

The EPA stated that this "settlement requires installation of four new flue gas desulfurization devices (scrubbers) to control SO2; four new baghouses to control particulate matter (soot); and operation of existing control equipment, including three selective catalytic reduction (SCR) systems, year-round to control NOx. The entire five-plant system will be subject to annual emission caps to assure that significant system-wide reductions for both SO2 and NOx are achieved."
