During regular environmental monitoring activities, two clay deposits from the Morice River micro-tunnel construction were identified. One of the two clay deposits was identified in a small tributary on the west side of the Morice River. With winter conditions still present, there is little water flow in the tributary. The other deposit was located on land and has been isolated.
Clay is used as part of the trenchless micro-tunneling process and is non-toxic.
Environmental professionals, including aquatic specialists, are working to remediate the site and install additional mitigation measures as required. Indigenous community members from the Construction Monitoring and Community Liaison team are on site to monitor and report to their communities.
As always, we are committed to being transparent in how we work. We have proactively informed regulators and local communities. We are working with them to ensure we continue to meet the high standards of environmental protection that is expected of us.
