GE Energy Services' coal-fired power plant in Homer City will be required to meet federal standards for emissions of sulfur dioxide that are more protective of human health.
The state Department of Environmental Protection announced in the Pennsylvania Bulletin last week that the power plant in Indiana County would be required to limit sulfur dioxide emissions to 6,360 pounds an hour, correcting a clerical mistake in the 1,884-megawatt facility's existing permit.
The DEP first imposed the sulfur dioxide limits, which equal the federal one-hour standard for sulfur dioxide controls, in April after reviewing company emissions projections as part of a settlement to a lawsuit by Earthjustice and the Sierra Club.
The 44-year-old plant is installing pollution controls on its two generating units for the first time. The facility emitted 109,000 tons of sulfur dioxide in 2010, according to Earthjustice, making it the largest source of the pollutant in the country.
The new pollution controls being installed by GE will reduce sulfur dioxide emissions by 100,000 tons a year. The power plant employs 265 and is a "base load" facility that generates enough power to supply 2 million homes.
