Trans Mountain's expansion at the Westridge Marine Terminal includes a new dock complex with three berths, a utility dock to moor tugs, boom boats and emergency response vessels, additional delivery pipelines and an extension of the land along the shoreline to accommodate new equipment.

The new dock complex will increase loading capacity from one Aframax-size tanker to the ability to load three Aframax-size tankers. Three new 30-inch delivery lines will be laid in a tunnel from Burnaby Terminal to supply each berth at the Westridge Marine Terminal.

We will be extending the land between the water and the terminal facilities (foreshore) further into the water. This extension will have:

  • Dock pipelines and metering equipment
  • Emissions management equipment
  • Fire-water and foam pumping system
  • Stormwater management system
  • Electrical equipment and control system
  • Space for potential future installation of vessel shore power facilities
  • New control building
  • Emergency response booms and areas for deployment of emergency response equipment

Marine habitat enhancements will be made according to federal Department of Fisheries and Oceans (DFO) and Vancouver Fraser Port Authority requirements.  Subject to approval of all applicable permits, rockfish habitat enhancements in the form of reefs for juvenile, intermediate and adult rockfish will be constructed in a designated area of the facility’s waterlot.

Westridge Marine Terminal Construction 

Typical of waterfront construction, most construction will occur from the water using floating equipment such as marine derricks, barges, tugs and workboats. Some construction may use land-based equipment working out into the water from shore.

Construction activities will include:

  • Site preparation activities to support ongoing operations including modifications and relocates of existing infrastructure; possible vegetation management inside terminal fence line
  • In-water construction including pile driving to accommodate new berths and trestles, as well as foreshore extension
  • Construction on the foreshore extension including rip-rap removal, installation of circular sheet pile cells, addition of structural fill, soil improvements, installation of foundations and construction of buildings, and installation of safety wall to separate terminal from existing train tracks; installation of equipment to support loading operations and emergency response enhancements
  • Construction on land including replacement of the existing substation, replacement of power line within the terminal, installation of new electrical cables, control systems and pipe
  • Tunnel portal construction and tunnel boring, installation of pipelines within the tunnel
  • Decommissioning and demolition of existing dock
  • Demobilization and site restoration

Construction of Berths 1 and 2 will take place first and are anticipated to be in-service in late 2019, supplied by the current pipeline until the expanded pipeline comes into service. Construction of Berth 3 will be completed after Berth 1 and 2 and is anticipated to be in-service by Q2 2020.

Dock Layout Selection Process

The Trans Mountain Expansion Project team has worked extensively with the Vancouver Fraser Port Authority (VFPA), the Pacific Pilotage Authority (PPA) and the BC Coast Pilots (BCCP) to determine a preferred dock layout. We have also incorporated feedback from the City of Burnaby and our community discussions in the planning.

During the evaluation and study process, we considered approximately 20 layouts. The one shown is considered the most optimal based on our objective to develop a layout that would provide: 

  • Three modern Aframax-capable berths with the highest level of navigational and mooring safety
  • Safe navigation room for all other marine traffic in the area.
  • Reduced use of anchorages east of the Second Narrows for tankers visiting Westridge
  • The ability to keep the existing dock in service during construction of the new dock system
  • Compact and optimized  overall footprint to minimize impact to community views
  • Opportunities to eliminate dredging in order to provide the least impact to the marine environment
  • Ways to operate with minimum disturbances, such as noise, to the residents of the neighbourhood

Construction Impacts

Trans Mountain is developing management plans to minimize disruption to neighbours. These plans include Traffic Management Plans, Construction Environmental Management Plans and plans to mitigate noise, lighting and emissions. More information about how Trans Mountain will manage construction impacts is available at here.  transmountain.com/construction.

We are currently developing traffic management plans to minimize disruption to neighbours when vehicles move to and from the Westridge Marine Terminal during construction that will take place over 30 months.

Some measures planned to reduce impact of truck- and construction-related traffic to Westridge Marine Terminal during construction include:

  • Construction workers will be bused to the site from a central yard off-site
  • Equipment required for marine works will be barged to the site
  • An alternate access for a small number of specialized vehicles will be planned for the north end of Cliff Avenue
  • Only vehicles required for work will be permitted onsite
  • Truck traffic staged on Bayview Drive north of Inlet Drive controlled by flag people and trucks will be parked with engines off
  • Maintain access to Drummonds Walk for pedestrians and bicycles
  • We continue to seek input from local residents and municipalities about preferences for receiving construction related information , which may include traffic control, changeable message boards and signage

View our Traffic Management Plan filed with the National Energy Board here.

The main hours of construction work at Westridge Marine Terminal are planned between 7 a.m. and 8 p.m., Monday to Friday and between 9 a.m. and 8 p.m. on Saturday. No work is planned on Sundays and statutory holidays. There is no pile driving planned outside of main construction hours, however, if required, night shift work may include maintenance activities and hand labour work that will not include continuous use of heavy equipment. All work will be measured and evaluated so as not to exceed Health Canada target noise generation guidelines as per the Trans Mountain Noise Management Plan for Construction at Pump Stations and Terminals.

In addition to marine terminal works, construction of the tunnel between Burnaby Terminal and Westridge, as well as other reduced noise activities upland from the foreshore may occur 24/7 or on Sundays.  

For detailed construction impacts read the Lower Mainland construction plan.

Management of Construction Impacts

Pile driving noise shrouds, new rock reefs and bird nest ‘sweeps’ are among the measures planned to mitigate environmental and community impacts from construction of the Project.

Here are some examples of measures Trans Mountain and its contractor, the Kiewit Ledcor TMEP Partnership (KLTP), will carry out to reduce or mitigate the impacts of construction at Westridge Marine Terminal:

Noise

Selected mitigation and noise control practices will be effective at limiting noise to the Health Canada recommended levels and desired British Columbia Oil and Gas Commission limits. For example, noise shrouds will cover the hammers that drive piles into the ocean floor, dampening the sound of hammer impact by 65 to 95 per cent.

Vibration 

In addition to noise mitigation through the use of noise shrouds, the contractor will primarily install the dock and trestle piles using a vibratory piling method reducing the use of an impact hammer as much as possible. Benefits of this approach will reduce noise and vibration on land, as well as reduce the intensity of noise below water and sound pressure emitted to the marine environment.

Lights 

Best management practices and mitigation measures will minimize the potential impacts from Project lighting on nearby receptor locations and marine users. For example, Trans Mountain will use directional lighting, properly installed and function light fixtures on the construction barge to avoid the use of secondary lighting with higher glare characteristics.

Extensive environmental mitigation measures are planned for Westridge Marine Terminal, as outlined in the Westridge Marine Terminal Environmental Protection Plan (a requirement of Condition 81).  Here are some environmental protection and mitigation measures:

Fish

Marine habitat enhancements will be constructed according to federal Department of Fisheries and Oceans (DFO) Fisheries Act Authorization and Vancouver Fraser Port Authority project permit requirements. As the terminal is in the vicinity of a DFO Rockfish Conservation Area, rockfish habitat enhancements in the form of reefs for juvenile, intermediate and adult rockfish will be constructed in a designated area on the west side of the terminal’s water-lot. 

Birds 

Vegetation clearing will be initiated outside the migratory bird nesting period (March 26 to August 17) as much as possible to reduce the potential for migratory birds nesting in areas where construction is to occur. If construction clearing is initiated during the migratory bird nesting period, a non-intrusive area search for migratory bird nests will be completed as necessary in consultation with a Wildlife Resource Specialist at least seven days prior to construction. 

In the event an active nest is found, it will be subject to site-specific mitigation measures (e.g., clearly marked species-specific buffer around the nest or non-intrusive monitoring). The appropriate mitigation measures will be selected by an Environmental Inspector, in consultation with a Wildlife Resource Specialist as described in the Wildlife Species of Concern Encounter and Discovery Contingency Plan which forms part of the Westridge Marine Terminal Environmental Protection Plan (NEB Condition 81 filing).

Marine Mammals

Impact pile driving may only commence if no marine mammals — including cetaceans, marine mammal species at risk and harbour seals — are observed within their respective exclusion zones for 30 minutes prior to the start of the activity. If a cetacean or marine mammal species at risk or a harbour seal is observed within its respective exclusion zone, impact pile driving will be temporarily suspended or rescheduled.

Storm Water Management 

The contractor will collect all storm water, surface water runoff and wash water generated from construction activities that contains or may contain suspended concrete materials and/or particles and treat the water prior to discharge as required by the Ministry of Environment and Climate Change Strategy. The contractor will use industry-accepted construction practices for placing concrete over water.

Navigation and Navigation Safety of the Terminal Construction Area

The construction work area for Westridge will be defined by a floating construction safety boom; which will be marked with appropriate navigation lighting and controls. The work area will consist of the entire expanded dock area as well as a temporary working area needed for the terminal’s construction.

Tugs, observation vessels and storage barges will be visible. Barges will host cranes, pile driving equipment as well as material storage, offices and other worker amenities.

Large commercial vessels navigating the area will continue to follow the well established vessel movement practices under pilotage. Recreational, tourism, Aboriginal and other waterways users are encouraged to take extra caution when nearing the area and to familiarize themselves with safety protocols while on the water, as per the VFPA Port Information Guide and the Canada Marine Act “Collision Regulations.” More information is available at here.

Traffic Management During Construction

Trans Mountain has developed plans ensuring construction impacts on traffic are well managed with least-possible impacts to commuters and other road-users. A Traffic and Access Control Management Plan was prepared to meet National Energy Board Condition 73 for the TMEP. It was developed in consultation with a wide range of stakeholders and government authorities. 

In addition, our contractors are required to develop plans for minimizing disruptions. Kiewit-Ledcor TMEP Partnership (KLTP) is the Contractor for Westridge Marine Terminal and is currently planning and scheduling construction activities at Westridge.

KLTP is establishing a 2.6-hectare office/yard on the north side of Barnet Highway to support this work. Primary road access to Westridge will be via traffic travelling about 2 km westbound on Barnet Highway and turning right onto Bayview Drive. Exiting traffic from Westridge will turn right from Bayview Drive westbound onto Barnet Highway, merging into the existing flow of traffic.  The pedestrian trail crossing at Bayview Drive will be maintained. Secondary access will be via Cliff Avenue.

Westridge Marine Terminal Access Points

Minimizing Worker Traffic

KLTP plans to reduce overall traffic by bussing the majority of workers to site at shift change and maximizing support for marine expansion at Westridge through Burrard Inlet.

Total average daily traffic associated with Westridge construction (AM and PM) is approximately 10 bus trips, 110 light vehicle trips and 35 transport truck loads. At the peak of construction, there will be approximately 15 total bus trips daily, 140 light vehicle trips and 50 transport truck loads.

Trans Mountain construction activities are planned with an objective to avoid adverse effects on traffic flows. Trans Mountain is requiring noise control measures for construction traffic and restrictions on idling.
