The Sumas-Anacortes segment of the Trans Mountain Pipeline (TMP) system will be shut for six days from November 18 for planned maintenance.
Known also as the Trans Mountain Puget Sound Pipeline (pink line) this segment get its supplies from the 300 Mb/d TMP system, sending it to four refineries north of Seattle in Washington state through the Sumas export point.
TMP runs from its receipt point in Edmonton, AB, with extra 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.
Its larger sibling, 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.
Separately, TMC has been carrying out unplanned maintenance October 7 through November 30 on its TMP system to give temporary protection for an exposed segment near Hope, British Columbia, at a crossing of a non-fish bearing stream. This work won't be impacting throughput, TMC said in an email.
