Pennsylvania DEP nears air permit decision for 1,040-MW CPV Fairview project

The Pennsylvania Department of Environmental Protection will hold a June 21 local public hearing on an Air Quality Plan Approval Application for the proposed CPV Fairview Energy Center in Jackson Township, Cambria County.

The hearing will be preceded by an open question-and-answer session beginning at 6:00 P.M. The public hearing will start at 7:00 P.M., said the department in a June 13 public notice.

CPV Fairview LLC is proposing to construct a combined cycle natural gas-fired station with an approximate generating capacity of 1,040 MW. Emissions from the main power block (combustion turbines and heat recovery generators) will be minimized through the installation of selective catalytic reduction and oxidation catalyst emission controls. 

CPV Fairview retained All4 Inc. to prepare this September 2015 air permit application. This application is needed to construct an air emission source and to install air cleaning devices as a major facility subject to permitting requirements for Prevention of Significant Deterioration and Nonattainment New Source Review. The project will consist of a two-on-one (2×1), nominal 980-MW plant that will include two combustion turbines (CTs), two heat recovery steam generators (HRSGs) with duct firing, and one shared steam turbine (ST).

Said the application: “The proposed state-of-the-art General Electric (GE) model (7HA.02) CTs will fire clean low sulfur pipeline-quality natural gas or a blend of low sulfur pipeline-quality natural gas and ethane, and will use ultra-low sulfur diesel (ULSD) as a backup fuel. For purposes of this application, the natural gas/ethane blend (i.e., ethane blend) is defined as a maximum of 25 percent (%) by volume ethane and a remainder of low sulfur pipeline-quality natural gas. The ethane blend will be utilized within the two CTs. In addition to the CTs and associated pieces of equipment, a cooling tower, an auxiliary boiler, two dew point heaters, two emergency generators, one fire water pump, one metering station, and four above-ground storage tanks (AST) will be included as part of the Project.

“The Project will use stringent, state-of-the-art control technology to limit air emissions to meet Best Available Control Technology (BACT), Pennsylvania Best Available Technology (BAT), and Lowest Achievable Emission Rate (LAER).

“The CTs and associated HRSGs will be equipped with a selective catalytic reduction (SCR) system to minimize NOX emissions and an oxidation catalyst to minimize both CO and VOC emissions from the CTs and HRSG with DBs.

“The Project will generate approximately 980 megawatts (MW) of power (nominal) to be distributed into the PJM Interconnection LLC (PJM) electric grid in the region. CPV Fairview plans to commence construction of the Project in late 2016, and plans to begin commercial operation of the Project in the 3rd Quarter of 2019.

“The Project will include one 12-cell mechanical draft, wet cooling tower for steam condensation. The cooling tower will operate continuously when the CTs and HRSGs are operated, and will emit small amounts of PM, PM10, and PM2.5 emissions, as ‘drift’ droplets. Emissions of ‘drift’, or, drift loss, will be minimized with high-efficiency drift eliminators. For purposes of the Project, the cooling tower may be operated up to 8,760 hours annually.

“The Project will also include a natural gas-fired auxiliary boiler, with a maximum heat input rate of 92.4 MMBtu/hr, which will be used only to provide high-temperature steam to accommodate more rapid ST startups after extended shutdowns when the CTs and HRSGs are offline. The auxiliary boiler will cease operation once the CTs have achieved steady-state operations and will operate no more than 4,000 hours per 12-month rolling period.

“Additionally, the Project will include two natural gas-fired dew point heaters, which are associated with the CT and HRSG operations and have a maximum heat input rating of 12.8 MMBtu/hr and 3.2 MMBtu/hr. The dew point heaters will operate as necessary to condition the natural gas and an ethane blend fuel prior to combustion, thereby preventing condensation, and each will operate up to 8,760 hours annually.”

This is one of several gas-fired projects listed on the website of Competitive Power Ventures.
