Residents in northern Westchester are upset about plans to build a new gas pipeline that would stretch from New England to the Hudson Valley.

A meeting was held in Cortlandt Manor on the issue Monday evening. Suzannah Glidden, an opponent to the Algonquin Pipeline project, founded the grassroots group Stop Algonquin Pipeline Expansion or SAPE. 

SAPE is fighting a plan by a Texas-based energy company to remove and replace a half-century old, 26-inch natural gas pipeline with a 42-inch pipeline. It would span Rockland County and run through Westchester and Putnam counties, and continue to Connecticut and Boston.

"An explosion of this enormous pipeline with very high pressure, so dangerously sited near Indian Point nuclear facility, would be an unimaginable catastrophe," said Glidden. She also says public health would also be at risk, due to emissions at compressor stations.

No decision was made by the Federal Energy Regulatory Commission Monday, but hundreds of people signed up to speak in a last-ditch effort to convince regulators to give the issue more time.
