647-Mile Montana-Wyoming Crude Pipeline Enters Public Review

Regulators have launched a public comment period for a proposed 647-mile crude oil pipeline linking Montana and Wyoming, a major project aimed at moving Canadian crude to U.S. markets.

(P&GJ) — Federal and state regulators have opened a public comment period for a proposed large-scale crude oil pipeline that would run from Montana into Wyoming, advancing early-stage review of the Bridger Pipeline Expansion project, according to reporting by KDH News .

The project calls for construction of a 36-inch-diameter pipeline stretching roughly 647 miles, designed to transport up to 550,000 barrels per day of Canadian crude to a hub near Guernsey, Wyoming. A significant portion of the route would cross eastern Wyoming counties, connecting with existing infrastructure that links regional oil production to downstream markets.

The U.S. Bureau of Land Management is leading the federal environmental review, working alongside multiple agencies to assess potential impacts on land, water and local communities. In parallel, Montana regulators are conducting their own review process tied to state permitting requirements.

Officials said the public scoping process will help identify environmental concerns, route alternatives and mitigation measures as the project moves through early planning stages. Public meetings are expected to follow as part of the review timeline.

The proposal comes as developers look to expand takeaway capacity for Canadian crude, though the project faces scrutiny tied to environmental risks and the operator’s past pipeline incidents, according to KDH News. Legal approvals, including a presidential permit for the border crossing, will be required before construction can begin.
