CUMULATIVE PHYSICAL IMPACTS of MARCELLUS SHALE DRILLING
Fully-exploited, the Marcellus in a 50 mile square area would provide enough gas to supply the US with gas for 4.1 hours
Land area: Barker 41 mi2 * Lisle 47 mi2 * Maine 46 mi2 * Nanticoke 24 mi2 * Triangle 40 mi2
HVHF= High Volume Hydrofracking
These figures are for 50 square miles at full build out*
1. # HVHF Marcellus drilling units in 50 square miles 1 = 50
2. # HVHF wells /separators2 = 350 wells
3. Truck trips: drilling/fracking equipment3 = 122,500 trips past our homes
4. RigWeeks required to drill all wells 4 = 1400 weeks (27 years) of noise
5. Hydrofracking fluid required (gallons)5 = 1,925,000,000 gallons
6. FrackDays required to frack all wells6 = 1750 days (4.7 years) of pounding
7. Toxic waste generated (gallons)7 = 479,250,000 gallons of poison
8. TRUCKTRIPS: toxic waste flowback3 = 87,500 round trips past your house
9. Gathering lines/pipes (miles)8 = infinitesimal

1 I unit / sq. mile (draft SGEIS p 5-20) plus 10% included through Compulsory Integration (est.)
2 average seven HVHF wells per pad (draft SGEIS p 5-20); one separator for each well (SGEIS p 5-127)
3 350 equipment trips per well; 500 hydrofracking liquid trips per well; 250 wastewater haul trips per well. (all trucking calculations draft SGEIS 9/30/09 p 6-138)
4 four weeks per well (draft SGEIS 9/30/09, p 5-23)
5 water usage figures range from 2million gallons per well, to 9 million gallons (draft SGEIS 9/30/09, p 5-92)5.5 million gals average
6 five days per well (draft SGEIS 9/30/09, p 5-93)
7 waste flowback calculated at 25% of injected fluids per well (draft SGEIS 9/30/09, p 5-97)
8 no state agency regulates gathering lines
*These figures pertain only to horizontal-drilled Marcellus shale production with only 7 wells per pad. The law allows for up to 16 vertical-drilled wells per sq mi in the Marcellus formation. Utica Shale drilling would have a similar, larger, additional impact. Other gas-bearing formations may also be drilled.
