American Bituminous Power Partners LP on May 17 applied with the West Virginia Department of Environmental Protection for approval of a federally-enforceable air permit limit for SO2 emissions of up to 2,000 tons per year out of its coal-fired Grant Town power plant in Marion County.
The plant features two circulating fluidized-bed combustors that were installed in 1992 and each have a design capacity of 551.9 mmBtu/hr. The plant is fired by waste coal left from prior mining in the region around the plant.
The new SO2 limit would go into effect on Jan. 13, 2017. The company said no plant changes would be needed to meet this new limit and the plant can operate fully under this new restriction. The new limit is under the 2010 1-hour National Ambient Air Quality Standards for SO2. The company is projecting actual SO2 emissions at the plant between 1,700-1,800 tons/year over the next few years. The 2015 SO2 emissions rate was 1,735 tons, down from 2,035 tons in 2014.
