2021 Preventative Maintenance Program
Enbridge uses ultra-high-tech inspection tools to monitor both the interior and exterior of our pipes. When data from these inspections indicates a change or anomaly that requires a closer look, Enbridge will undertake a maintenance dig to physically examine the integrity of the pipe segment and determine if a repair or other action is needed.
In late 2019, Enbridge launched a program to assess Line 21 from Norman Wells to Zama. The program, which continued into 2020, used two in-line inspection tools featuring higher resolution imagery than previous tools used on Line 21. As a result of these inspections, Enbridge is planning approximately seven maintenance digs in the Dehcho Region in Q1 of 2021. It is anticipated that all required maintenance digs will occur on the existing Line 21 ROW. We will also be conducting routine maintenance and ROW brushing on various segments along the ROW. For more information, please read our information bulletin.
5-Year Land Use Permit Renewal
In July 2020, Enbridge received approval from the Mackenzie Valley Land and Water Board for a Land Use Permit to allow ongoing operational and maintenance work on Line 21. The permit allows Enbridge to conduct activities off the ROW to operate and maintain Line 21 from Norman Wells to the Alberta border. For more information about this permit, read the Land Use Permit Renewal factsheet.
