In April 2018 Williams filed a request with the Federal Energy Regulatory Commission (FERC) to expand capacity along the mighty Transco Pipeline to increase the amount of gas the pipeline can flow to the Mid-Atlantic and Southeastern U.S by 296 million cubic feet per day. The Southeastern Trail expansion project (SET), as it’s called, was given final approval by FERC in October 2019 (see FERC Approves Transco Southeastern Trail Expansion Pipe Project). Last Friday Williams asked FERC for permission to begin construction in Prince William and Fauquier counties in Virginia.
