National Grid approved for new pipeline segment to serve New York cogen plant

The New York State Public Service Commission, in a decision made on May 14 and issued on May 19, approved a March 30 application from Niagara Mohawk Power d/b/a National Grid to build a new gas pipeline segment to serve a cogeneration plant in pace of a segment washed out in a flood.

National Grid was approved to amend its Certificate of Environmental Compatibility and Public Need that authorized construction of a 5,750-foot, 6-inch-diameter coated steel pipeline (Pipeline 61) in the City of Sherrill and Town of Vernon in Oneida County. In July 2013, the portion of Pipeline 61 running adjacent to and crossing beneath Sconondoa Creek in the City of Sherrill and the Town of Vernon was washed out and severed as a result of an unprecedented flood event.

The pipeline was, and is, the sole source of fuel to the Sterling Energy cogeneration facility in the City of Sherrill. In order to repair and return to service the damaged portion of the pipeline, National Grid constructed a temporary bridge over Sconondoa Creek and installed a temporary pipeline on it. National Grid then formally requested permission to amend its Certificate for the purpose of removing the temporary bridge crossing and installing a new permanent crossing across Sconondoa Creek.

As proposed, the approved project would consist of the following: removing from service the temporary aerial pipeline crossing of Sconondoa Creek; abandoning in place approximately 1,860 feet of existing underground pipeline; and installing approximately 1,335 feet of new six-inch diameter steel underground natural gas pipeline.
