The Pennsylvania Department of Environmental Protection said in a May 21 notice in the Pennsylvania Bulletin that it intends to issue an air plan approval to CPV Fairview LLC covering construction and temporary operation of a 1,020 MW (nominal) combined-cycle station known as the CPV Fairview Energy Center.
The project site is located at 2862 William Penn Avenue in Johnstown in Jackson Township, Cambria County. The facility will include two General Electric (NYSE:GE) 7HA.02 combustion turbines in a 2-on-1 combined-cycle arrangement equipped with heat recovery steam generators (HRSG) with supplemental 425 MMBtus/hr fired duct burners controlled by selective catalytic reduction and oxidation catalysts.
The combustion turbine fuels will be natural gas and an ethane blend (25% ethane and 75% natural gas, by volume), with ultra-low sulfur diesel (ULSD) fuel as back-up. The duct burners will utilize natural gas and the ethane blend only.
Ancillary emissions sources at the facility will include one 92.4 MMBtus/hr natural gas-fired auxiliary boiler with ultra-low NOx burners and flue gas recirculation, two 1,500 ekW ULSD-fired emergency generator engines, one 422-bhp ULSD-fired emergency fire pump engine, one natural gas-fired dew point heater with maximum heat input of 12.8 MMBtus/hr, one natural gas-fired dew point heater with maximum heat input of 3.2 MMBtus/hr, one 1,000,000-gallon ULSD storage tank, and a 12-cell mechanical draft wet cooling tower with high-efficiency drift eliminator.
Fugitive emissions sources will include eight sulfur hexafluoride insulated circuit breakers; natural gas and ethane blend metering, regulating, and associated piping components (including valves, flanges, relief valves, and sampling connections); and plant roadways.
CPV’s application for plan approval is subject to Prevention of Significant Deterioration (PSD) requirements, Nonattainment New Source Review (NSR) requirements and the requirement to meet Best Available Technology (BAT) needs. The department has determined that each proposed source at the facility meets best available control technology (BACT), lowest achievable emission rate (LAER), and BAT requirements.
All comments must be received prior to the close of business 30 days after the date of this May 21 notice. The DEP said it will hold a public conference and hearing on June 21 at Jackson Township Fire Hall, 176 Adams Avenue, Mineral Point, Pa.
Said the Competitive Power Ventures website for this project: “Competitive Power Ventures (CPV) is dedicated to developing electric generating facilities that help meet our future energy needs in an environmentally responsible manner. We focus on natural gas-powered electric generating facilities like the CPV Fairview Energy Center, and renewable energy facilities, as a means of achieving a cleaner energy future. We are proud to be working with the people of Jackson Township, Cambria County and the State of Pennsylvania to build this state-of-the-art energy center to help meet the energy and economic needs of over 1 miliion Pennsylvania homes.”
