Apache Generating Station
Apache Generating Station is a 408-megawatt (MW) coal-fired power station owned and operated by the Arizona Electric Power Cooperative near Cochise, Arizona.
One of the station's coal plants is set to switch to gas by 2018 to comply with EPA's regulation for regional haze.

Death and disease attributable to fine particle pollution from Apache Station
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.

Havana ranked 77th 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. The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.
Apache Generating Station ranked number 77 on the list, with 360,465 pounds of coal combustion waste released to surface impoundments in 2006.
"High Hazard" Surface Impoundments
Apache Generating Station has 7 coal ash surface impoundments on the EPA's official June 2009 list of Coal Combustion Residue (CCR) Surface Impoundments with High Hazard Potential Ratings. The rating applies to sites at which a dam failure would most likely cause loss of human life, but does not assess of the likelihood of such an event.
