Air Quality Division: Permits: Bowie Power Station

On October 16, 2014, the Arizona Department of Environmental Quality (ADEQ) issued Air Quality Control Permit Number 58787 to Bowie Power Station, LLC for construction and operation of a power generating facility located at Rosewood Road and Central Avenue, 2 miles north of Bowie, Cochise County, Arizona.

The planned Bowie Power Station will be a natural gas-fired, combined cycle power plant with a total rating of 1,050 Megawatts (MW) (nominal). This permit covers Phase 1, which is the first of two identical construction phases. Phase 1 comprises two combustion turbine generators (CTG), two heat recovery steam generators (HRSG) with duct firing, one steam turbine generator (STG), and one mechanical draft nine-cell cooling tower. Auxiliary equipment include a natural gas-fired boiler, one diesel-fired emergency fire pump, two evaporation ponds, and five circuit breakers.

Pollution control equipment for the CTG/HRSG units include dry low-NOX (DLN) combustors and selective catalytic reduction (SCR) for the control of nitrogen oxides (NOX), and oxidation catalyst for the control of carbon monoxide (CO), volatile organic compounds (VOC), and hazardous air pollutants (HAPs). The auxiliary boiler will be equipped with ultra-low-NOX burners and flue gas recirculation and the mechanical draft cooling tower will be equipped with high-efficiency drift eliminators. With the exception of the diesel-fueled fire pump engine, the only fuel used at the facility will be pipeline quality natural gas; there are no provisions for back-up fuels for the CTG/HRSG units or the auxiliary boiler.
