There are currently twenty-one coal-fired power plants in Missouri. Seven of those, each with toxic coal ash disposal sites, are on the banks of the Missouri River, which supplies drinking water for 54% of the state’s residents. Four coal-fired power plants owned by Ameren Missouri surround the greater St. Louis area. Most of these coal plants are decades old. Ameren's newest was built almost 40 years ago and only one of Ameren's four plants has added pollution controls, while the rest emit toxic chemicals with impunity.
- Sulfur Dioxide (SO2)
- Particulate Matter
- Nitrogen Oxide (NOx)
- Carbon Dioxide (CO2)
- Other toxic and heavy metals
Ameren Missouri and other utilitites dump these toxic chemicals into our air and water leaving St. Louis area and Missouri residents to pay the price. According to a report by the American Lung Assocation the air quality in St. Louis County receives a "D" grade - barely passing.

The Sierra Club is working to ensure that Ameren and other coal-burning utilities pay for their pollution, protect our families, and clean up our communities. At a minimum, we are asking for credible groundwater monitoring, air pollution protections, and a moratorium on new coal ash disposal sites.
