Unit retirements
Units 1 and 2 were retired in 2005 after Unit 1's tubing to its boiler failed. Inspections on Unit 2 revealed severe corrosion in a pattern that was similar to Unit 1. The reported cost of $35 million to repair both units was not worth the benefit of returning to service.[1][2]
On June 9, 2011, AEP announced that, based on impending EPA regulations as proposed, AEP’s compliance plan would retire nearly 6,000 megawatts (MW) of coal-fueled power generation.[3] Conesville Unit 3 (165 MW) would be retired by Dec. 31, 2012, and Units 5 and 6 (800 MW total) would continue operating with retrofits.[4]
Unit 3 was retired in December 2012 in order to comply with EPA regulations.[5][6]
Units 5 and 6 were originally slated to close down in 2022, but in 2018 the company said market conditions could lead to their mothballing as early as May 2019.[7] Units 5 and 6 retired on May 31, 2019 while Unit 4 will remain in operation until May 2020.[8]
In May 2020 EAP retired unit 4, the last operating unit of the coal plant. [9][10]

Death and disease attributable to fine particle pollution from Conesville Power Plant
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.[11] 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.[12]
Table 1: Death and disease attributable to fine particle pollution from the Conesville Power Plant
| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 44 | $320,000,000 |
| Heart attacks | 70 | $7,700,000 |
| Asthma attacks | 670 | $35,000 |
| Hospital admissions | 32 | $760,000 |
| Chronic bronchitis | 26 | $11,000,000 |
| Asthma ER visits | 36 | $13,000 |

Coal Waste Sites
Conesville ranked 64th on list of most polluting power plants in terms of coal waste
In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of coal combustion waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill.[13] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[14]
Conesville Power Plant ranked number 64 on the list, with 447,846 pounds of coal combustion waste released to surface impoundments in 2006.[13]
Study finds dangerous level of hexavalent chromium at Ohio coal waste site
A report released by EarthJustice and the Sierra Club in early February 2011 stated that there are many health threats associated with a toxic cancer-causing chemical found in coal ash waste called hexavalent chromium. The report specifically cited 29 sites in 17 states where the contamination was found. The information was gathered from existing EPA data on coal ash and included locations in Alabama, Arkansas, Delaware, Florida, Illinois, Indiana, Minnesota, Massachusetts, North Carolina, North Dakota, Nevada, Ohio, Oklahoma, Pennsylvania, Tennessee, Virgina and Wisconsin. In Ohio, the Conesville Power Plant in Coshocon County and Industrial Excess Landfill in Uniontown were reported as having high levels of chromium seeping into groundwater.[15]
According to the report, the Conesville Power Plant coal ash site is a landfill. Hexavalent chromium (Cr(VI)) was reported at the site at 100 ppb (parts per billion) - 5,000 times the proposed California drinking water goals and above the federal drinking water standard.[15][16][17][18][19]
As a press release about the report read:
- Hexavalent chromium first made headlines after Erin Brockovich sued Pacific Gas & Electric because of poisoned drinking water from hexavalent chromium. Now new information indicates that the chemical has readily leaked from coal ash sites across the U.S. This is likely the tip of the iceberg because most coal ash dump sites are not adequately monitored.[20]
According to the report, the electric power industry is the leading source of chromium and chromium compounds released into the environment, representing 24 percent of releases by all industries in 2009.[15]
