In 2006, the plant emitted 86,174 tons of sulfur dioxide (SO2) into the air. Its SO2 emission rate per unit of electricity produced was 26.68 lb/MWh in 2006, ranking 2nd worst in the United States. In 2008, Cayuga Station's flue-gas desulfurization (FGD) for Units 1 and 2 went online reducing the station's SO2 emissions by approximately 95%.3
