Harding Street Station
|This article is part of the Global Energy Monitor coverage of coal plants|
Harding Street Station (also known as E.W. Stout Generating Station) was a coal-fired power station owned and operated by AES in Indianapolis, Indiana.
The plant stopped burning coal in February 2016.
In August 2014 the company said it would convert all three of the station's coal-fired units to natural gas by 2016.
The plant stopped burning coal in February 2016, with a planned conversion to run on natural gas by April 2016.

Death and disease attributable to fine particle pollution from Harding Street
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.

EPA "high hazard" dam
In November 2011, the EPA released a new set of coal waste data that revealed 181 “significant” hazard dams in 18 states - more than three times the 60 significant-hazard ponds listed in the original database released in 2009. In addition to the increase in the number of significant hazard-rated ponds, eight previously unrated coal ash ponds were found to be high hazard ponds in information released by the EPA earlier in 2011. Because of the switch in ratings after the EPA inspections, the total number of high hazard ponds has stayed roughly the same at a total of 47 ponds nationwide.
According to the National Inventory of Dams (NID) criteria, “high” hazard coal ash ponds are categorized as such because their failure will likely cause loss of human life. Six states that gained high hazard ponds include:
- Indiana: Harding Street Station, Indianapolis: 2 high hazard ponds
