Trans Mountain Pipeline (TMP) will undergo unplanned maintenance from October 7 through November 30 to give temporary protection for an exposed segment at a crossing of a non-fish bearing stream, its operator said in a filing with the Canadian regulator. The segment is near Hope, British Columbia.
Operator Trans Mountain Corporation (TMC) said the segment was exposed during the 2021 floods, and more recent inspections revealed that conditions have deteriorated. Work will be taking place on existing right-of-way and Trans Mountain’s privately held property. It isn’t clear if the maintenance will impact operations for the system.
Meanwhile, permanent remediation work is being designed, and will be submitted for permitting; once approved, construction will take place in the summer of 2025.
The 300-Mb/d Trans Mountain Pipeline (TMP; solid green line in Figure below) runs from its receipt point in Edmonton, AB, with more small receipts entering via Kamloops, BC, before reaching the 55-Mb/d Parkland Corp.-owned Burnaby refinery (blue triangle; in Burnaby, BC), or for export from the Westridge docks (yellow star) about 2 miles (3 km) north of the refinery. The network carries a wide range of crudes.
Its twin, the 590-Mb/d Trans Mountain Expansion (TMX, dashed green line) which experienced plenty of setbacks leading up to its eventual startup in May 2024, runs roughly parallel to TMP.
