Death and disease attributable to fine particle pollution from Conemaugh
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.[9] 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.[10]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 27 | $200,000,000 |
| Heart attacks | 46 | $5,000,000 |
| Asthma attacks | 430 | $22,000 |
| Hospital admissions | 21 | $490,000 |
| Chronic bronchitis | 16 | $7,200,000 |
| Asthma ER visits | 20 | $7,000 |

EPA Violations
According to New York Times compilation of 2009 EPA data the plant has violated the Clean Water Act 392 times without paying any fines.
GenOn pays $5 million settlement for violations
In June 2011, GenOn Northeast Management Co. agreed to pay $5 million to settle a 2007 lawsuit alleging its discharges of potentially toxic heavy metals helped pollute a river and violated its permits thousands of times. The plant sits on the Conemaugh River, about 50 miles east of Pittsburgh.
Since at least 2005, the plant violated the federal Clean Water Act "practically every day" by discharging excessive amounts of aluminum, boron, iron, manganese and selenium in the approximately 2 million gallons of water it dumped into the Conemaugh each day, according to PennEnvironment and the Sierra Club, the environmental advocacy groups that filed lawsuit. Some of the metals are toxic, and can harm aquatic life in a river already damaged by acid mine drainage from coal mines, the environmental groups say.
The $3.75 million portion of the settlement is the largest penalty in Pennsylvania history against a water polluter under the citizen enforcement provision of the federal Clean Water Act. Of that, $3.5 million is would help support environmental cleanups in the Conemaugh River watershed, while $250,000 is a civil penalty. GenOn also must pay $1.25 million for the groups' legal expenses.[11]
Unlined coal ash dam
In January 2023, the US Environmental Protection Agency (EPA) proposed the refusal of applications from six coal-fired power stations to dispose of coal ash in unlined dams. The EPA stated that the utilities operating the power stations failed to demonstrate how they would meet groundwater protection regulations. The impacted power stations were Belle River Power Plant, Coal Creek Station, Conemaugh Generating Station, Coronado Generating Station, Martin Lake Steam Station and Monroe Power Plant.[12]
Proposed Conemaugh mine
There is a proposal to mine 49 acres of a farm in Conemaugh Township. The Dovey family has asked the planning commission to rezone a portion of their 400-acre property to allow PBS Coals Inc. to begin strip mining. More than 300 residents turned out at a meeting in April 2011 in the Conemaugh Township fire hall to give their views. The property, which is located near Carpenters Park, is now zoned for single and multiple family residential, and the family is seeking a change to rural residential, which would allow PBS to bring the application process in summer 2011. If approved, work is expected to begin in the fall of 2012 and be completed in two years. The company plans to take out 10,000 tons of coal each month. Trucks will carry the coal along Miller Picking Road to Route 403, to Route 219 and Route 30 to a coal preparation plant in Central City. About 10 percent of the coal will be for domestic use; the rest will be shipped overseas for the steel industry.[13]
