Most PA gas leaves Pennsylvania and goes to New York City and other Northeast markets, meaning that the impact of gas drilling stays local, while the gas itself goes to the region. A new $1 billion pipeline, proposed by UGI and its partners, could keep more gas local, by delivering another approximately 300 billion cubic feet per year or 25% of Pennsylvania's 2011 gas production to Pennsylvania"s homes and businesses. http://articles.philly.com/2012-03-02/news/31117210_1_pipeline-route-natural-gas-ugi
New York has been doing two things: buy shale gas drilled in Pennsylvania to save money and to stay warm, while stopping shale gas drilling in New York.
Of course, Pennsylvania has had the lease income, the royalty checks that have changed lives, the direct jobs, the indirect jobs, the much lower gas and electricity bills--lots of benefits from drilling that plenty of New Yorkers want as well. But dealing with the impacts caused by industrial gas drilling and then sending the gas to NY has left a bad taste in the mouths of more than a few Pennsylvanians.
Gas drilled in Pennsylvania should stay in Pennsylvania if possible.
