Q&A

A: Moricetown will have the opportunity to participate in construction monitoring via the Construction Monitoring and Community Liaison Program. When there is a project agreement in place, a related Liaison committee will facilitate discussion between Moricetown and Coastal GasLink Pipeline to address any environmental or cultural issues that may arise during construction or operation of the project. As background, Environmental Inspectors are an integral part of the construction management team, providing advice on major decisions or courses of action to address unexpected environmental conditions encountered during construction. Coastal GasLink Environmental Inspectors will be responsible for:

  • monitoring environmental and construction conditions and working with our field management, when necessary, to ensure compliance with our environmental commitments, approvals, permits and licenses;
  • documenting the effectiveness of measures we take to reduce potential adverse environmental effects and recommending additional or alternative measures;
  • identifying resource-specific issues; and
  • the status of environmental issues after pipeline construction.

A: In 2014 and 2015, TransCanada employed over 80 Wet’suwet’en community members to conduct field work on the project. This enabled them to gain employment, and enabled TransCanada to incorporate local knowledge into the project plans which is a priority. Pipeline construction requires thousands of part-time and temporary workers during the pre-construction and construction phases, and a smaller number of permanent employees are required once the pipeline is operational. Prime contractors are required to hire qualified Aboriginal and local subcontractors. These relationships are critical to the success of the pipeline project and operations while benefiting local communities.

A: The entire pipeline is underground. The Coastal GasLink Project will include the construction of some above ground facilities. Facilities that are visible above ground include mainline block valve stems, pig launchers and receivers, compressor stations, and meter stations.

A: The pipeline will be buried beneath the river. It is important to construct and operate the pipeline to avoid or reduce the potential for adverse effects on water resources. Waterways are of particular environmental concern to Aboriginal groups and to communities along the pipeline route. The company assess’ potential pipeline installation methods and locations at watercourse crossings along the proposed route. Additional information will be gathered at the Morice River that will support detailed engineering design and further inform the crossing plan with the intent of avoiding or reducing potential adverse effects.

A: If a site or artifact is discovered during construction, activity in the immediate area will be stopped, and we will implement our Heritage Resource Discovery Contingency Plan. Coastal GasLink’s Construction Manager, Heritage Resource Specialist and the Environmental Inspector will be notified. The site will be assessed to understand the specific location in relation to the construction footprint, the significance of the site, the feasibility of refining the construction footprint to avoid the site, and any regulatory requirements. The process also includes communication with the affected First Nation through our ongoing discussion during construction.

A: No. TransCanada is an energy infrastructure company. They are not involved in the exploration and production of oil or natural gas - they only transport it.

A: If the proposed agreement with CGL is approved, the right-of-way clearing (clearing the way for the pipeline) will start mid to end of June.

A: If an emergency occurs in the system, TransCanada quickly confirms the exact location of the emergency and identifies affected facilities. Valves spaced at intervals throughout the pipeline system shut off the flow of gas and allow the incident to be effectively isolated. Trained crews are dispatched to the adjacent facilities to assist with the isolation and to establish an Incident Command Post.

A: All of the pipelines are monitored 24 hours a day by trained operators who respond immediately to any indication of abnormal operation.

Cleaning and inspection tools called “smart pigs,” are pushed along inside the pipeline using the pressure of the natural gas itself. These tools gather data for the assessment of pipeline integrity. The information gathered helps shape our pipeline maintenance programs. When certain anomalies are detected, the pipeline segment in question is excavated and visually inspected. It is either repaired on the spot or replaced.

A: TransCanada uses high-quality steel and best construction practices when building pipelines. All pipe is tested well above normal operating pressure before it is put into operation. Our pipelines are cathodically protected, which means a low-voltage electric current is induced in the vicinity of the pipeline to inhibit external corrosion.
