Coal Ash Waste and Water Contamination

In August 2010 a study released by the Environmental Integrity Project, the Sierra Club and Earthjustice reported that North Dakota, along with 34 states, had significant groundwater contamination from coal ash that is not currently regulated by the Environmental Protection Agency (EPA). The report, in an attempt to pressure the EPA to regulate coal ash, noted that most states do not monitor drinking water contamination levels near waste disposal sites.[1] The report mentioned North Dakota's Antelope Valley Station and Leland Olds Station as sites that have groundwater contamination due to coal ash waste.[2]

Antelope Valley CO2 capture demonstration project

In January 2009, the U.S. Department of Agriculture announced a loan of up to $300 million to Basin Electric Power Cooperative for the development of a demonstration project to capture carbon dioxide emissions at its Antelope Valley plant in Mercer County. Basin Electric is partnering with Powerspan Corp. and Burns & McDonnell to demonstrate CO2 removal from the flue gas of a lignite-based boiler. The project would capture about a million tons of CO2 per year from part of the plant's exhaust stream and send it to oil fields along the pipeline used by the plant.[3]

In July 2009, the project received up to $100 million from the Department of Energy's Clean Coal Power Initiative.[4]

Some state representatives are seeking $100 million in state support to match the federal grant. The project's initial engineering and design work should be completed by the end of 2010, Basin spokesman Daryl Hill said. North Dakota's Industrial Commission, which oversees a state coal research fund, put up $2.7 million for the study, which equaled half its expected cost.[5]

In August 2010, Basin Electric Power Cooperative said it was searching for customers to buy the carbon dioxide it plans to retain from the experimental Antelope Valley power plant. A potential buyer is the oil industry, which uses carbon dioxide for enhanced oil recovery in some geologic formations. Designers hope the project will be able to capture up to 1 million tons of the gas annually. The legislative committee's chairman, Sen. Rich Wardner, R-Dickinson, said he believed a surge in carbon dioxide demand was in the offing for western North Dakota's oil industry.[6]

The carbon dioxide retention process to be used at Antelope Valley is being developed by HTC Purenergy Inc. of Regina, Saskatchewan and Doosan Babcock Energy, an English company that has its U.S. headquarters in Atlanta. Basin said the carbon dioxide that cannot be sold could be pumped underground into saltwater aquifers in western North Dakota for storage. One large aquifer is beneath the Freedom Mine, eight miles northwest of Beulah, which supplies coal to the synfuels plant and Antelope Valley station.[6]

Death and disease attributable to fine particle pollution from Antelope Valley 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.[7] The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma-related episodes and asthma-related emergency room visits, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, peneumonia each year are attributable to fine particle pollution from U.S. coal-fired power plants. Fine particle pollution is formed from a combination of soot, acid droplets, and metals formed from sulfur dioxide, nitrogen oxide, and soot. Among those particles, the most dangerous are the smallest (smaller than 2.5 microns), 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. 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. The table below estimates the death and illness attributable to the Antelope Valley Station. 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.[8]

Type of Impact Annual Incidence Valuation
Deaths 52 $380,000,000
Heart attacks 80 $8,700,000
Asthma attacks 870 $45,000
Hospital admissions 37 $870,000
Chronic bronchitis 32 $14,000,000
