October 1, 2020: Trans Mountain is near completion of the response phase at the Sumas Pump Station in Abbotsford, BC, following a release in June 2020. Trans Mountain continues to work in close cooperation with Stó:lō representatives, including Semá:th First Nation, regarding monitoring and site activities.
An Action Plan is being developed in accordance with the Canada Energy Regulator (CER) Remediation Process Guide and will outline the remediation strategy for the next year.
Trans Mountain has provided written reports on site activities, waste volumes, groundwater monitoring and sampling results to regulators (CER, Environment and Climate Change Canada and BC Ministry of Environment) and Indigenous community representatives. Daily groundwater monitoring of 40 monitoring wells, along with air monitoring, have not indicated any risk to the public or surrounding community and there has been no migration of product off the Trans Mountain facility property.
Trans Mountain has conducted a thorough investigation into the incident and has fully cooperated with the Transportation Safety Board and the CER. Our assessment is that the release is related to a fitting on a small diameter (1”) piece of pipe connected to the mainline.
