Unit Retirements
According to a January 2013 agreement between MidAmerican Energy and the Sierra Club, boiler one and boiler two (49 MW and 82 MW respectively) will be retired by April 16, 2016.[8]
Units 1-2 were retired in 2015.[9]
Fines
In 2003, MidAmerican began building a fourth plant, Council Bluffs Energy Center Unit 4. Unit 4 began operating on June 1, 2007; Lincoln Electric System later acquired 12.6% ownership of the plant. In 2007, Plains Justice filed a federal lawsuit on behalf of the Iowa Chapter of the Sierra Club with the U.S. District Court for the Southern District of Iowa. The suit charged MidAmerican Energy with violating the Clean Air Act by operating new sources of carbon emissions without proper permits, and constructing these new sources without first obtaining approval from the Iowa Department of Natural Resources. In June 2007, MidAmerican Energy agreed to pay $27,500 in fines after the attorney general’s office filed a lawsuit claiming MidAmerican Energy had operated “11 emission points” at the Walter Scott Jr. power station without proper permits from the Iowa Department of Natural Resources. Sierra Club is preparing to file a second lawsuit over emissions. [10][11]

Death and disease attributable to fine particle pollution from Walter Scott Jr.
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.[14] 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.[15]

| Type of Impact | Annual Incidence | Valuation |
|---|---|---|
| Deaths | 8 | $59,000,000 |
| Heart attacks | 13 | $1,400,000 |
| Asthma attacks | 140 | $7,000 |
| Hospital admissions | 6 | $140,000 |
| Chronic bronchitis | 5 | $2,200,000 |
| Asthma ER visits | 9 | $3,000 |

Walter Scott Jr. ranked 35th 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.[16] The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.[17]
Walter Scott Jr. power station ranked number 35 on the list, with 1,092,320 pounds of coal combustion waste released to surface impoundments in 2006.[16]
