Trans Mountain has a comprehensive and robust pipeline integrity management program that encompasses a broad spectrum of preventive measures to ensure pipeline soundness and reliability, safety of the public and employees and protection of the environment. These preventive measures include continuous 24/7 monitoring of the pipeline, in-line inspections, pipeline investigations and cutouts, natural hazards management and corrosion protection programs, damage prevention and public awareness programs.

As part of our integrity management program, we will be completing scheduled pipeline investigations on the existing pipeline in several areas throughout Alberta and BC.

Pipeline investigations are typically based on inline inspections using tools called smart pigs. When a smart pig runs through the pipeline, a report is generated following a detailed analysis by the tool vendor. The Integrity group receives the report, assesses the findings and puts together a plan to expeditiously investigate any anomalies that have been identified. The investigative digs may require obtaining approvals and permits from landowners, First Nations, and various government and municipal authorities and conducting environmental assessments. Our goal is to ensure that the pipeline continues to operate safely and reliably while minimizing the impact of this work on both the public and the environment and complying with all applicable standards and regulatory requirements.

The upcoming maintenance projects will involve segments of pipe being excavated and inspected using non-destructive examination methods. If required, repairs will be completed, the sites backfilled and restored to the original or better condition. During these projects, the areas near the worksites may experience increased traffic and construction activity. Construction noise may also be present.
