If you live or work near our pipelines, it’s important to call or click before you dig to avoid damaging buried utilities and ensure your safety. While pipelines are the safest and most efficient way to transport petroleum products to market, a pipeline can be damaged if direct contact occurs during excavation or other ground disturbances. These incidents commonly result from working near Trans Mountain’s infrastructure without our prior knowledge or consent.

Two frequent ground disturbance activities are described below:

Fence Installation and Repairs

The installation and replacement of fence posts are among the most common actions that can accidentally damage underground utilities and put your safety at risk. The property owner or a hired contractor is responsible for reaching out to a local One Call service before starting work.

Vehicle Crossings

Another frequent ground disturbance activity is vehicle or mobile equipment crossing over the pipeline. While it’s allowed on public roads, crossing over the pipeline when not driving on an existing road requires a safety assessment by Trans Mountain. Additional pipeline protection measures may be considered, including rig matting, additional cover or identification of an alternate crossing.
