Toxic Coal Ash in Alabama: Addressing Coal Plants’ Hazardous Legacy

For decades, utilities disposed of coal ash – the hazardous substance left after burning coal for energy – by dumping it in unlined ponds and landfills. Alabama has 32 coal ash dumpsites.

Alabama is one of the nation’s top coal ash-generating states, ranking ninth in ash production in 2005.

Coal ash contains hazardous pollutants including arsenic, boron, cobalt, chromium, lead, lithium, mercury, molybdenum, radium, selenium, and other heavy metals, which have been linked to cancer, heart and thyroid disease, reproductive failure, and neurological harm.

Industry’s own data indicate that across the country 91% of coal plants are currently polluting groundwater above federal health standards with toxic pollutants.

Coal ash remains one of our nation’s largest toxic industrial waste streams. U.S. coal plants continue to produce approximately 70 million tons every year.

Despite EPA’s 2015 Coal Ash Rule, which created the first-ever safeguards for coal ash disposal, many coal ash dumps remain unregulated due to sweeping exemptions for legacy coal ash ponds and inactive landfills.

The exempted coal ash dumps are sited disproportionately in low-income communities and communities of color. The EPA issued a proposed rule to address most of these exemptions on May 17, 2023.

Action Needed

The magnitude of harm from recklessly dumped toxic coal ash requires decisive action from federal and state regulators.

  • Utilities must be required to comply with the law and immediately clean up their pollution.
  • EPA and states must make enforcement a priority and act quickly to ensure that utilities leave communities with sites that benefit rather than harm their health, environment, and economic status.
  • EPA must swiftly strengthen the Coal Ash Rule to address the many legacy ponds and inactive landfills that are unregulated, and to prohibit coal ash used as fill unless protective measures are put in place, to ensure all Alabama communities are protected from coal ash pollution.

16 Regulated Coal Ash Disposal Sites in Alabama

Alabama utilities operate 16 federally regulated coal ash ponds and landfills at eight plants that contain more than 118 million cubic yards of toxic waste.

Coal ash has caused significant groundwater contamination at all of Alabama’s regulated dumpsites. In fact, five of the state’s eight power plants rank among the top 25% of the most contaminated coal ash sites.

Alabama utilities, however, have failed to initiate any plant-wide cleanups to restore water resources despite the legal requirement to do so.

In addition, Alabama Power is planning to close in place unlined coal ash impoundments with ash in contact with groundwater, which is prohibited by the federal rule and which would ensure continued contamination at those sites.

All data on groundwater contamination from coal ash derived from the utilities’ publicly accessible CCR Compliance Data and Information websites, and exceedances were calculated by Environmental Integrity Project.

16 Unregulated Coal Ash Legacy Ponds and Inactive Landfills in Alabama (ash dumps exempted from the 2015 Coal Ash Rule)

In addition, Alabama hosts 16 unregulated inactive coal ash landfills and legacy ponds at three active and retired coal plants. The exact number remains unknown because utilities are not required to report these sites.

These dumps are almost certainly contaminating water and threatening health and the environment; however, monitoring data are not currently available for most unregulated sites.

As we anticipate EPA’s proposed rule on legacy ponds and unregulated landfills in May 2023, a concern remains that the agency will not address coal ash that was dumped off site or used as fill.

These data were developed by using EPA datasets relied upon in their 2007 and 2014 CCR risk assessments (Human and Ecological Risk Assessment of Coal Combustion Residuals) and comparing those datasets to the universe of regulated units.

“EPA damage case” denotes a site where US EPA has found documented groundwater contamination from coal ash.
