Respecting the Environment
Minimizing our environmental impact
Environmental responsibility is about doing the right thing, not always the easiest thing. To help reduce our footprint and make informed decisions about Coastal GasLink, our team has been working hard to proactively identify and mitigate potential issues. This means:
- Collecting information about the local environment and sensitive environmental features for construction planning, and identifying appropriate measures to mitigate potentially adverse effects.
- Conducting field studies to gather further details about heritage resources, vegetation, wetlands, soil, wildlife and aquatic habitats.
- Engaging with Indigenous communities to collect Traditional Land Use information and Traditional Ecological Knowledge and to learn about potential concerns and issues.
Using the information collected, our team developed the environmental assessment and protection plans for regulatory approval, and in October 2014, we received our Environmental Assessment Certificate. In May 2016, we received all of our BC Oil and Gas Commission permits. In April 2016 we also received the required approvals for our various environmental and socio-economic management plans. As we continue to prepare for construction, we will use the information collected to develop applications for the remaining permits to support construction of the project.
Prior to construction, TC Energy secures rights to strips of land called rights-of-way. They are approximately 45 metres wide to construct the pipeline and approximately 32 metres wide for the operating life of the pipeline. Once Coastal GasLink is in operation, vegetation will be managed over about 10 metres across the pipeline, to keep the area above it clear of trees, branches and invasive plants or weeds. The pipeline will be underground, except at valve sites and compressor stations.
We’ll conserve topsoil on agricultural land, to maintain land capability. While we maintain right-of-way easement for the life of the project, we work with landowners to address any concerns caused by pipeline activities.
Did you know? TC Energy’s environmental practices have been internationally recognized for:
- Being one of the first companies to apply horizontal directional drilling versus open cut for larger river crossings.
- Pioneering the use of innovative winter construction techniques through short grass prairie ecosystems to ensure minimal impacts.
- Investing significantly in the preservation and enhancement of endangered species habitats.
- Adopting and developing new technology to make our pipelines more energy efficient and reduce greenhouse gas emissions.
- Applying mobile compressors to reduce methane emissions during maintenance programs.
When planning our pipeline route, we consider environmental factors, stakeholder and community feedback and constructability.
