FERC approved a final stage of construction for the Dalton pipeline expansion being built by Williams Cos. Inc.'s Transcontinental Gas Pipe Line Co. LLC that keeps the project on track to begin delivering an extra 448,000 Dth/d of natural gas to Georgia in 2017.

A Dec. 13 FERC order granted authorization to build three remaining meter stations in Virginia. Construction is expected to be completed in January 2017. Construction of the project facilities began in October 2016.

"We're on track with our timeline," Williams spokesman Christopher Stockton said.

The project's targeted in-service date is mid-2017. Transco, a Williams Partners LP subsidiary, received a certificate order from FERC on Aug. 3 for a project the company expected to cost about $471.9 million. When FERC granted the authorization, it said certain proposed modifications required additional information from Transco.

The project will deliver additional gas from supply areas in the Northeast to northwest Georgia for utility companies and the city of Cartersville, Ga. The new facilities, including about 115 miles of various diameter pipeline, will extend Transco's pipeline system from Coweta County, Ga., to new delivery points in Paulding and Murray counties in Georgia. The facilities also include one compressor station, the three meter stations and other components in Virginia, North Carolina and Georgia. (FERC docket CP15-117)
