Natural gas Meter station Compressor station Mainline pipe Potential future Mainline pipe Kitimat Meter supply (Wilde Lake) compressor stations Station What is a compressor station? As natural gas flows along a pipeline, the pipeline, the diameter of the it slows due to friction with the pipe, pipe, elevation changes along the resulting in a drop in pressure. To keep pipeline route and the volume of gas the gas flowing at a required rate, it is transported. re-pressurized at locations along the pipeline. This is done by mechanically Coastal GasLink is advancing compressing the gas at sites connected construction of one compressor station to the pipeline, known as compressor at Wilde Lake. Should a decision be stations. made about potential future increase in capacity, up to seven additional The location and number of compressor compressor stations could be stations needed on a pipeline system constructed, as permitted as part of is dependent on a number of factors, the project’s Environmental Assessment including the operating pressure of Certificate (EAC). Example of a compressor station What is a meter station? A meter station measures the amount Coastal GasLink is beginning of natural gas that enters and exits the construction of meter facilities at both pipeline. Meter stations also ensure the Kitimat and Wilde Lake facility that the natural gas in the line meets locations. Should a decision be made required specifications. These stations about potential future increase in are used at all locations where natural capacity, additional meter infrastructure gas enters the pipeline (receipt meter could be constructed at the Wilde Lake station) or leaves the pipeline (delivery and Kitimat facilities, as permitted as or sales meter station). part of the project’s EAC. Example of a meter station 2 — Coastal GasLink Compressor and Meter Facilities Safety is our number one value Safety is our number one value when planning, constructing, and operating compressor and meter stations. A number of safety systems are built Compressor stations and meter into the stations to ensure the safety stations are monitored 24/7 by safety of the facility, our employees, the systems, which automatically shut surrounding community, and the the system down in case of abnormal environment. The pipeline is constantly operating conditions. Technicians monitored for any abnormalities. If will also be employed to monitor and a potentially hazardous condition is maintain each compressor station recognized, the system would be shut location.

Environmental considerations Coastal GasLink will meet strict environmental and safety standards, while meeting the growing global demand for cleaner energy. The project, including compressor and meter stations, was approved through a rigorous multi-year environmental assessment, which included extensive fieldwork and consultation and engagement with local and Indigenous communities. The assessment considered the potential Environmental studies are underway to effects of the project on a number of support decision making on potential environmental factors such as soil, future facility additions, including air wildlife, aquatic resources, air quality, dispersion modeling, noise assessments, noise, land use, and traditional uses. and archaeological studies. Activities related to construction Engagement with Indigenous and local and operations will be managed to communities is an important part of the protect the environment through evaluation of any potential future facility environmental mitigation measures, additions. management plans, and environmental monitoring. Coastal GasLink Compressor and Meter Facilities — 3 Minimizing community impacts Coastal GasLink is committed to be used for earth-moving, excavation minimizing impacts on the local material handling/hauling, welding community throughout construction and testing. Equipment may include and operation of the project. Where graders, bulldozers, backhoes, bucket there may be localized impacts from wheel trenchers for pipeline sections, noise or increased traffic volumes, these welding equipment, portable cranes and activities and potential impacts are sideboom cranes. expected to be short in duration and in many cases, in remote areas away from Coastal GasLink will adhere to all communities. applicable codes, standards and regulations on noise throughout During construction, there will be construction and operation of the heavy equipment on-site, which will facilities. Timeline Construction along the 670 kilometre-long project is underway. Coastal GasLink continues to engage with Indigenous and local communities as construction progresses, and is assessing potential options to improve the capacity of the project. This could involve the construction and operation of up to seven additional compressor stations to move natural gas more efficiently through the pipeline, as approved in our environmental assessment certificate (EAC). 2012 2014 2016 2017 2018 2019 2020–2021 2023 LNG Canada B.C.
