{{#badges: CoalSwarm| Climate change}} Iatan Generating Station is a coal-fired power station owned and operated by Great Plains Energy near Weston, Missouri.

In 2010, Iatan 2 went online. In April 2011, the Missouri Public Service Commission voted 5-0 to approve Kansas City Power & Light’s (KCP&L) request for a $34.8 million rate increase. KCP&L initially sought an increase of $92.1 million, stating higher than expected running costs of the new Iatan 2 plant as the primary reason for the increase request. Under the new agreement, which will go into effect May 4, 2011, roughly 350,000 customers in Kansas City will see an estimated increase in their monthly bill of $4.85 (5.23%). Starting in June 2011, customers once served by Aquila Inc.’s Missouri Public Service and St. Joseph Light and Power will also pay higher annual rates. This is the fourth rate increase KCP&L has been granted since 2005.[1]

Death and disease attributable to fine particle pollution from Iatan Generating 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.[2] 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.[3]

Type of Impact Annual Incidence Valuation
Deaths 9 $63,000,000
Heart attacks 13 $1,400,000
Asthma attacks 150 $8,000
Hospital admissions 6 $150,000
Chronic bronchitis 5 $2,400,000
Asthma ER visits 9 $4,000

Coal Waste

Iatan ranked 94th 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.[4] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[5]

Iatan Generating Station ranked number 94 on the list, with 240,245 pounds of coal combustion waste released to surface impoundments in 2006.[4]
