  • El Paso Natural Gas Company

    El Paso Natural Gas Company, L.L.C. (EPNG), a Kinder Morgan Company, provides natural gas transportation services for natural gas suppliers and end users throughout the southwestern United States and owns and operates a large pipeline network.  The Vail compressor Station  is one of such stations that provides natural gas compression to the pipeline network.  Natural gas compression is needed to maintain enough pressure in the pipeline to keep the natural gas flowing, and it is accomplished with three natural gas fired turbines that drive the compressor units.  The facility is permitted to operate 24 hrs a day and 365 days a year.

    The proposed project expects to trigger a major modification for NOx and CO subject to the Prevention of Significant Deterioration (PSD) permitting. As such, air quality dispersion modeling analysis is required to demonstrate that new emissions from the major modification, will not cause or contribute to a violation of any National Ambient Air Quality Standards (NAAQS).
