FERC has approved Williams’ request to commence partial path service by September 1, 2017, of the Mainline A and B Replacement facilities and Compressor Station 185 valve and yard piping modifications in Prince William County, Virginia, and Compressor Station 190 regulator valves in Howard County, Maryland, as part of the Atlantic Sunrise Project.
The Atlantic Sunrise Project includes the following:
- Approximately 183 miles of new greenfield pipe (Central Penn North & Central Penn South)
- Two pipeline loops totaling about 12 miles (Chapman Loop, Unity Loop)
Two and half miles of existing pipeline replacement, two new compressor facilities in Pennsylvania
- Other facility additions or modifications in five states (Pennsylvania, Maryland, Virginia, North Carolina, South Carolina)
Once finished, the project will add 1.7 million dekatherms per day of pipeline capacity to Williams’ Transco system, and is expected to be placed in service in 2018.
