Appalachian installing sulfur scrubbers at plant
CHARLESTON, WEST VIRGINIA - Appalachian Power says the first of three sulfur dioxide scrubbers being installed at its John E. Amos in Putnam County plant is expected to begin operating by mid-March.
The American Electric Power subsidiary said the Unit 3 scrubber will produce a billowing white cloud of steam when it begins operating. Appalachian Power said the scrubber will reduce sulfur dioxide emissions by up to 98 percent.
The utility says workers are still installing scrubbers on Amos' two other units. The entire project is expected to cost approximately $1 billion.
