Effect on Our Towns

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 mi * 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

draft Supplemental Generic Environmental Impact Statement  (SGEIS)

http://www.dec.ny.gov/energy/58440.html

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.
