FERC readies enviro review on Transco’s Dalton Expansion Project

The Federal Energy Regulatory Commission on April 2 issued a notice about a March 19 application from Transcontinental Gas Pipe Line Co. LLC (Transco) for authority to construct and operate its Dalton Expansion Project.

Transco has requested to construct approximately 111.2 miles of new pipeline and install a new 21,830 horsepower compressor station in Carroll County, Georgia. The proposal will provide 448 million cubic feet (MMcf) per day of firm capacity on Transco’s system. The estimated cost of the project is $471.9 million.

Within 90 days of this April 2 notice, the commission staff will issue a notice of schedule for environmental review. If that notice of schedule is issued, it will indicate, among other milestones, the anticipated date for the commission staff’s issuance of the environmental assessment (EA) for this proposal. The issuance of a notice of schedule will serve to notify federal and state agencies of the timing for the completion of all necessary reviews, and the subsequent need to complete all federal authorizations within 90 days of the date of issuance of the commission staff’s EA.

The project will enable Transco to provide 448,000 dekatherms per day (dt/day) of incremental firm transportation capacity from Transco’s Station 210 Zone 6 Pooling Point in Mercer County, New Jersey, along Transco’s mainline to Transco’s interconnection with Gulf South Pipeline Co. LP at Holmesville in Pike County, Mississippi, and through a new pipeline lateral (called the “Dalton Lateral”), initiating at Transco’s Compressor Station 115 in Coweta County, Georgia, to interconnections on the Dalton Lateral in northwest Georgia.

Transco requests that the commission issue a final order granting these authorizations by March 1, 2016, which will enable Transco to maintain the construction schedule required to meet the May 1, 2017, target in-service date for the project.

The project delivery points include points of interconnection with Atlanta Gas Light Co. in Bartow and Murray counties, Georgia, and Oglethorpe Power Corp.’s Thomas Smith Plant in Murray County, Georgia. In addition, a new, 21,830 horsepower compressor station (“Compressor Station 116”) is proposed to be located on the Dalton Lateral in Carroll County, Georgia.

Transco said it has executed binding precedent agreements with Atlanta Gas Light and Oglethorpe for 100% of the incremental, year-round firm transportation service to be provided under the project.
