Well Pad Footprint (3 acres/well pad )Water Storage (3- 15 acres/impoundment)

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

Scope and Scale of Transmission Impacts

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.

Edge Effects on Forest Interior Species

Increased light

Reduced humidity

Increased invasive species

Increased predation

Increased storm damage (trees)

Reduced mobility (animals)

Environmental Impacts of Transmission ROWs

Physical Impacts

Soil disturbance/erosion

Noise (electrostatic)

Noise (compressor

stations)

VOC and methane

emissions (natural gas)

Light (large electric lines)

Chemical use/spills

Mowing/cutting vegetation

Ecological Impacts of Transmission ROWs

Habitat fragmentation

Increased predation

Vectors for invasive species

Bird and bat fatalities (electric)

Animal travel corridors

Favorable sites for early successional/grassland species


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
