Death and disease attributable to fine particle pollution from Flint Creek Power 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 affects attributable to fine particle pollution from coal-fired power plants. The study found that over 13,000 deaths and hundreds 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 heavy 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 Flint Creek Power 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.

Coal Waste Site
Flint Creek ranked 96th 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. The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.
Flint Creek Power Plant ranked number 96 on the list, with 221,456 pounds of coal combustion waste released to surface impoundments in 2006.
Coal Ash Waste and Water Contamination
In August 2010 a study released by the Environmental Integrity Project, the Sierra Club and Earthjustice reported that Arkansas, 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. The report mentioned Arkansas based Flint Creek Power Plant and the Independence Steam Station were two sites that have groundwater contamination due to coal ash waste.
The 2010 EarthJustice, Environmental Integrity Project, and Sierra Club report, "In Harm's Way: Lack of Federal Coal Ash Regulations Endangers Americans and their Environment," identified 39 more coal combustion waste (CCW) disposal sites in 21 states that have contaminated groundwater or surface water with toxic metals and other pollutants, including Flint, based on monitoring data and other information available in state agency files. The report builds on an earlier 2010 report by the Environmental Integrity Project and Earthjustice, "Out of Control: Mounting Damages from Coal Ash Waste Sites", which documented similar damage at 31 coal combustion waste dumpsites in 14 states. When added to the 67 damage cases that the U.S. Environmental Protection Agency (USEPA) has already acknowledged, the total number of sites polluted by coal ash or coal scrubber sludge comes to at least 137 in 34 states.
The report found that the groundwater downgradient of the Flint coal waste landfill has been contaminated with lead up to 33 times the Maximum Contaminant Level (MCL), barium, selenium, cadmium and chromium exceeding the MCL, and iron, manganese and silver exceeding Arkansas groundwater standards. 2009 assessment monitoring found selenium at 3 times the MCL, and sulfate and total dissolved solids TDS at 8 and 5 times the SMCL, respectively, in a well 360 feet downgradient from the landfill. A seep with high metals discharges to a stream that drains to ash ponds, which then discharge to an off-site recreational reservoir without limits or monitoring of ash metals. 45 private wells are within a 2-mile radius of the plant. Six public intermittent wells are within a 5-mile radius of the plant.
Study finds dangerous level of hexavalent chromium at Flint Creek waste site
A report released by EarthJustice and the Sierra Club in early February 2011 stated that there are many health threats associated with a toxic cancer-causing chemical found in coal waste called hexavalent chromium. The report specifically cited 29 sites in 17 states where the contamination was found. The information was gathered from existing EPA data on coal ash and included locations in Alabama, Arkansas, Delaware, Florida, Illinois, Indiana, Minnesota, Massachusetts, North Carolina, North Dakota, Nevada, Ohio, Oklahoma, Pennsylvania, Tennessee, Virgina and Wisconsin. In Arkansas, the Flint Creek Power Plant was noted as having a high level of chromium at its coal waste landfill.
According to the report, the Flint Creek coal ash site is a landfill. Hexavalent chromium (Cr(VI)) was reported at the site above 128 ppb (parts per billion) - 6,400 times the proposed California drinking water goals and 1.28 times the federal drinking water standard.
As a press release about the report read:
- Hexavalent chromium first made headlines after Erin Brockovich sued Pacific Gas & Electric because of poisoned drinking water from hexavalent chromium. Now new information indicates that the chemical has readily leaked from coal ash sites across the U.S. This is likely the tip of the iceberg because most coal ash dump sites are not adequately monitored.
According to the report, the electric power industry is the leading source of chromium and chromium compounds released into the environment, representing 24 percent of releases by all industries in 2009.
