Pennsylvania works on permitting 485-MW Archbald Energy Partners project

The Pennsylvania Department of Environmental Protection is soliciting comments on a proposed Air Quality Plan Approval for Archbald Energy Partners LLC to construct and operate a natural-gas-fired combined-cycle (NGCC) plant to produce approximately 485 MW.

This facility is to be located in Archbald Borough, Lackawanna County. The company filed this application on Feb. 2, said the agency in a notice in the Sept. 24 Pennsylvania Bulletin.

This combined-cycle plant would consist of a combustion gas turbine (CT) and a steam turbine (ST) with duct burners in the heat recovery steam generator (HRSG), one diesel-fired emergency generator, one diesel-fired fire water pump, an air-cooled condenser, and one aqueous ammonia storage tank.

The company proposes to construct a NGCC plant consisting of a General Electric model 7HA.02 or equivalent natural-gas-fired combustion turbine. The HRSG will be equipped with natural-gas-fired duct burner (DB). The facility will be capable of producing approximately 485 MW (nominal). The maximum heat input rating of the CT is 3,269 MMBTUs/hr. The DB will have a maximum heat input rating of 111 MMBTUs/hr.

The company proposes to control the nitrogen oxides emissions using a dry low-NOx (DLN) combustor and selective catalytic reduction (SCR). To control the carbon monoxide (CO) and volatile organic compounds (VOCs) emissions, the company proposes to utilize combustion controls and oxidation catalysts.

The 670 bhp diesel-fired emergency generator and the 450 bhp diesel-fired fire pump will be restricted to a maximum of 100 hours of operation each, in any 12 consecutive month period, for non-emergency operation. The maximum sulfur content of the diesel fuel fired in these engines will be 15 ppm.

The DEP will hold a hearing on Oct. 26 at Valley View High School in Archbald, Pa. Persons unable to attend the hearing can submit written testimony through Nov. 4.

The company address is: Archbald Energy Partners LLC, 72 Glenmaura National Blvd., Moosic, PA 18507.
