The Federal Energy Regulatory Commission has approved a natural gas pipeline expansion project in the region.  Spectra Energy received approval Tuesday and opponents have a month to file an appeal. 

Spectra plans to replace a pipeline segment with a larger one, starting at the Southeast Compressor Station and extending into Danbury near the Still River and Mill Plain Road.  It would end at an existing Algonquin site located east of Clapboard Ridge Road. 

The proposed construction work area would be located within 50 feet of 337 residential structures and 95 non-residential structure.
