Ameren Missouri coal-fired generation historical SO2 emissions.
- Ameren started reducing sulfur dioxide (SO2) emissions long before the 1990 Clean Air Act amendments were passed, meeting our reduction goals well ahead of schedule. Actual emissions are significantly below required levels.
- Using low-sulfur coal has helped reduce SO2 emissions rate by 87%.
- Ameren Missouri's Energy Centers operate below the Environmental Protection Agency's (EPA) current allowable emissions levels that are fully protective of human health. See graph for Ameren Missouri coal-fired generation historical SO2 emissions.
- Using scrubber pollution control systems removes more than 95% of the SO2 emissions at Sioux Energy Center.
- Ameren anticipates further controls will be necessary to meet federal regulations. Various pollution control methods will continue to be implemented to reduce SO2, NOx, mercury and particulate.
- Ameren estimates spending between $2 billion and $3 billion by 2020 on solutions that meet or exceed new requirements.
- Ameren continues to support research of more effective emission control technology.
