Service Discontinuing on Colonial’s Mitchell Junction to Roanoke, Va., Pipeline – Line 25

Colonial plans to discontinue service on Line 25, a stubline delivering petroleum products to the Roanoke, Va., market from its Mitchell Junction Tank Farm in central Virginia. This decision was made due to Colonial’s ongoing concerns about the long-term integrity of the stubline. Colonial reduced flow-rates on the stubline in March 2017 out of an abundance of caution and to ensure the stubline’s continued, safe operation.

The stubline will continue to run at a reduced rate as Colonial decommissions the line, a process expected to take up to one year. This period will allow shipping customers to make alternate plans for supply. The scheduled time for the stubline to be removed from operational service is September 2018. Colonial is establishing a website to answer questions about this decision. Shippers may submit additional questions on the website. The link is


Here is an example of the Q&A’s you can expect to see as we receive and respond to your questions:

Why is Colonial taking this line out of service?

While we have not identified issues that impact current operations, our inspection process has identified line conditions that will require extensive maintenance over time.

Is the line safe?

Yes, we are currently operating the line safely and at reduced pressure and flow rates.

Why not replace the line?

We considered several options, including replacement of the line, however we have determined it would be best to focus priorities and resources on other key integrity and maintenance projects.

What does this line transport and what are the origins?

Line 25 transports gasoline and other fuels from Colonial’s Mitchell Junction tank farm in Columbia, Va., to five terminals serving customers in the Roanoke area.
