Units 1-3 were built in the 1960-70s.[1] Dallman Unit 4 began operating on June 1, 2009.[2][3]

In October 2023, the Illinois Attorney General filed a lawsuit against City, Water, Light and Power (CWLP), alleging that the utility's Dallman Station released over 700 tons of coal ash into the environment in August 2021.[4]

Planned retirement

Units 1-2 retired on schedule in December 2020.[5] Unit 3 was schedule to retire by 2023.[6] However, storm damage sustained in 2021 caused CWLP to retire the station early due to the high costs of repair it would take to return the unit to service.[7]

Death and disease attributable to fine particle pollution from Dallman

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.[8] 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.[9]

Type of Impact Annual Incidence Valuation
Deaths 3 $23,000,000
Heart attacks 5 $540,000
Asthma attacks 54 $3,000
Hospital admissions 3 $54,000
Chronic bronchitis 2 $880,000
Asthma ER visits 3 $1,000
