NEW YORK, Nov 7 (Reuters) -

New York environmental regulators on Friday approved a water

permit for U.S. energy company Williams Cos' ( WMB )

long-delayed and controversial Northeast Supply Enhancement

natural gas pipeline project in New York, New Jersey and

Pennsylvania.

The project is controversial in part because it was

previously rejected by environmental regulators in New York and

New Jersey and canceled by Williams before U.S. President Donald

Trump sought its revival.
