Carbon Power Plant was a coal-fired power station owned and operated by Rocky Mountain Power, a subsidiary of MidAmerican Energy (which is owned by Berkshire Hathaway) near Helper, Utah. The plant was scheduled to be retired in April 2015. According to Rocky Mountain Power, the reason the plant was being closed was the cost of meeting new mercury regulations.[1]

The plant was taken offline April 15, 2015.[2]

Death and disease attributable to fine particle pollution from Carbon Power Plant 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.[3] 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.[4]

Type of Impact Annual Incidence Valuation
Deaths 5 $35,000,000
Heart attacks 7 $800,000
Asthma attacks 100 $5,000
Hospital admissions 3 $77,000
Chronic bronchitis 3 $1,500,000
Asthma ER visits 4 $2,000
