Uinta Express Pipeline

To link Uinta Basin’s waxy crude oil production with the Salt Lake area refineries, Uinta Express Pipeline Company, a subsidiary of Tesoro Refining and Marketing LLC, is proposing to build the Uinta Express Pipeline.

The project will consist of an approximately 135-mile, 12-inch, buried, insulated, carbon steel pipeline and ancillary facilities.  It will be a common carrier pipeline with an expected capacity to be around 60,000 barrels per day.  Market conditions and further analysis will determine the project’s precise specifications.

The proposed pipeline will provide a safe and efficient way to move waxy crude currently being trucked to the refineries.  The pipeline will take about 250 tanker trucks off the road daily that are making roundtrips from the Uinta Basin to Salt Lake City.  The project will generate an economic boost by creating temporary and permanent jobs, facilitating the usage of local Utah crude and helping to provide an important piece of energy infrastructure to meet demand.


The final Environmental Impact Statement (EIS) and Draft Record of Decision will be released in December 2015 followed by a 45-day objection period. The U.S. Forest Service will issue its final Record of Decision once this period is complete.




Three complimentary work streams are currently ongoing for the project

EIS Work Stream: The U.S. Forest Service (USFS),
the lead agency on the project, is overseeing the Environmental Impact Statement (EIS) process for
the project’s full 135 miles.  The USFS’s staff and contractor will be analyzing five alternatives in detail in the EIS. The USFS will also continue working with the Cooperating Agencies during the Environmental analyses.

Engineering Work Stream: Tesoro and its engineering team will move to more detailed engineering for the project. They will continue conducting engineering studies and modeling, and identify design elements of the pipeline, such as the location of valves and pump stations, and how best to cross each river, stream or wetland. Where appropriate, this material will be incorporated into the EIS and the plan of development.

Stakeholder Engagement Work Stream: Tesoro, its right-of-way agents and communications team, will continue engaging proactively with the state, counties, cities and landowners to provide good information, listen, answer questions, find workable solutions when needed and identify project deliverables.

Each of these work streams plays a role in defining the project and construction considerations.
