Answering your questions about the Amherst incident

You have questions about the Amherst incident, and we want to make sure you have the information you need to feel confident in our response. If you have a question not covered below, please email us here.

We put a high priority on the safety of the public and our employees, all while protecting the environment. We do this by actively and regularly ensuring that our pipelines are built to the highest standards. We also regularly monitor all our infrastructure through advanced technology and aerial as well as physical inspections. If a leak occurs – such as in this case – we immediately investigate and take the necessary actions to contain the leak and remediate the area.

In all circumstances, we take full responsibility for emergency response and cleanup for any of the pipelines that we own and operate.

There was no impact to groundwater. We completed groundwater sampling at 12 groundwater monitoring wells and no impacts were found.

We respond immediately by shutting down and isolating the pipeline systems and/or shutting down the pump or compressor stations and dispatching emergency response personnel. The main focus of the initial response is to stop operating the pump or compressor units in order to reduce the flow through that particular segment of pipe and then close isolation valves in the vicinity of the leak to limit its impact.

In the unlikely event that a leak occurs, our company takes full responsibility for the emergency response and cleanup for as long as we own and operate the pipeline.

We create Emergency Response Plans (ERP) for every pipeline and project in our system. These plans must be in place before the pipeline ever goes into operation. While plans may vary depending on project and community needs, the basic elements of a plan will include hazard identification, notifications and response tactics to ensure TransCanada personnel are able to effectively respond in the event of an emergency.

All our ERPs are developed through a detailed and comprehensive program specific to the project and communities in which we operate. This includes gathering necessary and important feedback from local communities and emergency responders during the planning stages.
