There’s nearly a month left in a public comment period for an environmental review of natural gas drilling in New York, but environmentalists have gone beyond requesting changes to the document — they’re asking that it be repealed all together.

New York’s recently released review of the environmental risks posed by natural gas production in the Marcellus Shale offers the clearest picture yet of the chemicals used in the drilling process called hydraulic fracturing.

A long-anticipated draft environmental review laying out proposed laws for natural gas drilling in New York’s Marcellus Shale has been released by the state after 18 months of study and several delays. But according to a summary it would not ban drilling inside the New York City watershed, a central Catskill Mountain area that supplies drinking water to 9 million people.
