Conversions and retirements

Biomass Conversion at Mitchell Plant.

On March 19, 2009, the Georgia Public Service Commission approved a request from Georgia Power to convert the coal-fired power plant to burn woody biomass. When the transition is completed, Mitchell will be the first biomass plant in the fleet of Georgia Power's parent Southern Company and "the largest biomass facility in the United States," according to Southern COO Tom Fanning.[1]

In January 2014 Georgia Power said the company is canceling a 2008 proposal to convert Plant Mitchell Unit 3 from a coal-fired unit to biomass and plans to file a request with the Georgia Public Service Commission (PSC) to decertify the 155-MW unit. If the decertification is approved, it will be retired by April 16, 2015, which is the compliance date of the United States Environmental Protection Agency's (EPA) Mercury and Air Toxics Standards (MATS) Rule.[2]

Death and disease attributable to fine particle pollution from Mitchell Plant

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.[4] 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.[5]

Type of Impact Annual Incidence Valuation
Deaths 10 $72,000,000
Heart attacks 14 $1,500,000
Asthma attacks 160 $8,000
Hospital admissions 7 $160,000
Chronic bronchitis 6 $2,600,000
Asthma ER visits 10 $4,000

Legislative issues

House Bill 276, proposed by Margaret Oliver (D-Decatur), would put a 5-year moratorium on building new coal plants and eliminate the burning of Appalachian coal mined by mountaintop removal by mid-2016. The Appalachian Mountain Preservation Act would gradually prohibit Georgia coal consumers from using Central Appalachian mountaintop removal beginning in 2011. The bill is backed by environmental groups including Appalachian Voices but received strong opposition from POWER4Georgians, a coalition of 10 electric co-operatives seeking to build a $2 billion 850-megawatt supercritical coal plant in Washington County.[6][7]
