Environmental impact[edit]

Sulphur dioxide[edit]

With its oldest coal-fired unit dating back to 1958, the plant was ranked 12th on the United States list of dirtiest power plants in terms of sulphur dioxide emissions per megawatt-hour of electrical energy produced from coal in 2006. The new flue gas desulphurization system (FGS), also known as a scrubber, and the new stack are expected to reduce sulfur dioxide (SO2) emissions by 97 percent, and NOxemissions, as well as other pollutants, by some 87 percent.[citation needed]
