GenOn Northeast Management Co. is seeking an air permit from the Pennsylvania Department of Environmental Protection (DEP) to allow the construction of a truck coal receiving area at the Keystone Generating Station located in Plumcreek Township, Armstrong County.
The DEP on Feb. 14 published in the Pennsylvania Bulletin a notice that it intends to approve this application. All comments on this planned approval must be received prior to the close of business 30 days after the date of this Feb. 14 notice publication.
“The truck coal receiving area will be to enhance the overall coal receiving and blending capabilities at Keystone, allowing up to 1,000,000 tons of coal to be delivered by truck,” said the notice. “It will be located within the existing permitted area at Keystone adjacent to the existing rail coal receiving area and near the existing limited truck coal receiving area. New and modified air contamination sources include increases to plant roadway vehicle traffic, coal delivery by truck to feeders or storage zones, feeder conveyors, a new collection conveyor, extension of an existing conveyor, and miscellaneous associated transfer points.
“This plan approval does not authorize any increase to the permitted heat input to the electric generating units and there is no projected change in emissions from those units. Best available technology (BAT) for coal delivery by truck is delivery by covered trucks, paving of delivery roadways, and a roadway dust control plan which includes sweeping and watering as necessary. BAT for feeders and storage zones is partial enclosure by wind barriers and watering as necessary. BAT for conveyors and transfer points is partial enclosure with a minimum coal moisture content of 5% to full or underground enclosure.”
Keystone is co-owned by several parties, though the ownership mix is changing. Exelon ((NYSE: EXC), for example, recently sold its stakes in Keystone and nearly identical Conemaugh coal plant to an affiliate of equity investor ArcLight Capital Partners. Also, PPL Corp. (NYSE: PPL) is proposing under a pending deal to turn over its stakes in Keystone and Conemaugh to the planned independent power producer Talen Energy.
The Conemaugh Station is a 1,711 MW (summer/winter rating) facility located in New Florence, Pa. The Keystone Station is a 1,711 MW (summer/winter rating) facility located in Shelocta, Pa.
