Compressor Stations (5 acres/station)Compressor Stations (5 acres/station)
Modeled the relationship between:
• Drilled and permitted Marcellus wells (from PA-DEP data)
• Spatial variables related to geology and infrastructure:
- Thermal Maturity- Shale Depth- Shale Thickness- Percent Slope- Distance to Roads- Distance to Pipelines

How Many New Gas Pipelines in U.S?
298,000 miles of natural gas transmission pipelines in U.S.
160,000 miles of hazardous liquid pipelines.
At least 5,000 miles of large diameter transmission pipelines are being built
annually.Photo: Nels Johnson - TNC

How Many New Gas Pipelines in PA?
PA had 9,000 miles of large diameter oil/gas pipelines in 2008
Pipeline mileage in PA will at least quadruple by 2030.
The gathering pipeline footprint alone is larger than the cumulative area
impacted by all other Marcellus gas infrastructure combined.

Minimizing Impacts of Transmission ROWs
Negotiate routing early and often
Work with other organizations to
promote preferred routes and
ROW maintenance
Advocate EIS through FERC
Specify desired vegetation
treatments ahead of time
Encourage hardscaping and
landscaping
