On September 1, 2015, Williams and Steelhead LNG announced a pre-construction agreement to start the preliminary design and regulatory approval process.
Developing a pipeline proposal spans several years and involves a number steps and activities including extensive environmental and engineering studies along with Tribal, Aboriginal, landowner and stakeholder engagement.
For the portion of the IGC Project located in the United States, Williams will start the pre-filing process in 2017 for the Federal Energy Regulatory Commission (FERC) certificate application. At the end of the pre-filing process, FERC will determine the timeline for the next steps.
In 2017, Steelhead LNG will file a Project Description, for the Canadian portion of the proposed project, with the National Energy Board (NEB) in Canada and continue field work and various studies associated with the proposal.
Tribal, Aboriginal, landowner and public engagement will continue in both the United States and Canada throughout all stages of the proposed IGC Project.
If approved by regulators – the FERC in the United States and the NEB in Canada – construction of the proposed Island Gas Connector Project, the section located in Washington State, would begin as early as summer 2019. The anticipated pipeline in-service date is November 2020, subject to approvals.
