 Compressor Station 206 Franklin Township (Somerset County)

 

New compressor station consisting of two natural gas-powered turbine-driven compressor units planned to be built on a 52-acre lot -total horsepower: 32,000

Two 50-foot smokestacks where:

  • Exhaust Exits At 210,000 cubic feet per minute
  •  Exit Temperature Is 849.2 degrees fahrenheit

Emissions include:

  • 13 pounds of carbon monoxide per hour
  • Ammania, formadehyde, benzene, and other toxic airborne carcinogenic chemicals
