Pipeline Operations

Westover Express Pipeline Limited (WEX)

WEX recently acquired the former Enbridge Line 10 pipeline, which Enbridge will continue to operate and maintain until April 2023. The pipeline carries oil from Enbridge Pipeline’s terminal in Westover, Ontario to United Refining Company’s 78-mile-long Kiantone Pipeline in West Seneca, New York to supply United’s approximately 70,000 barrel-per-day (“bpd”) refinery in Warren, Pennsylvania. 

Emergency Management

WEX is committed to preventing damage to people, the environment, and property. To ensure uninterrupted safe operation and response during the transition from Enbridge to WEX operation, the pipeline’s Emergency Management program will continue to be managed by Enbridge on WEX’s behalf until April 2023. The following link directs you to Enbridge’s Emergency Management Program webpage, which includes up to date information and manuals related to the former Line 10.


Line 10 Abandonment Trust 

In 2009 the National Energy Board, now the Canada Energy Regulator (CER), set out a process to ensure that funds are in place to meet future abandonment obligations associated with pipelines, as well as processing and other above-ground facilities. 

As part of that process, Westover Express maintains a trust to set aside funds to cover those future abandonment costs.  Certain Enbridge Pipelines affiliates began collecting, and contributing to the trust, abandonment funds at the beginning of 2015 as the predecessor Certificate holder.  Below are audited financial statements for the Line 10 Abandonment Trust, as well as the associated financial reporting forms (Appendix XV), which includes information required by the CER.
