Over the past two years, Trans Mountain has been undertaking fieldwork and studies to help assess the proposed pipeline corridor between Edmonton, AB and Burnaby, BC. Trans Mountain would like to be able to tell residents of Burnaby where the pipeline route will go in Burnaby and in order to do so, further on-the-ground fieldwork is required.

In July 2014, Trans Mountain filed a notice under National Energy Board (NEB) Act Section 73 to access City of Burnaby lands in order to conduct engineering and environmental studies for the proposed pipeline route in the Burnaby, including the Burnaby Mountain area. On August 19, the NEB confirmed Trans Mountain’s Section 73 rights.

The work will take place at various locations around Burnaby; the work on and around Burnaby Mountain will help determine the feasibility of routing a two-km section of the proposed pipeline between the Burnaby Terminal and the Westridge Marine Terminal through Burnaby Mountain Conservation Area. We are committed to ensuring the work is done with the least impact possible, and to fully restore any areas we disturb.

Within the Burnaby Mountain Conservation Area Trans Mountain began preparatory geotechnical work on Tuesday, September 3. This work includes the following:

Tree clearing and brushing work - At one of the two work locations, seven Red Alder trees deemed in health decline by a professional arborist were removed in order to provide a safe working area for the geotechnical investigations (three standing stumps, three deemed danger trees, one with a rotting core) - All seven trees are pioneer species (first to grow, first to die) and between 40-60 years old - A 20 x 20 metre “canopy” is required in order for the workers to safely carry out the testing without overhanging branches - On the ground, the space required for the equipment is 8 x 10 metres

Drilling - Two four-inch bore holes, approximately 250 m in depth, will take core samples at two locations within Burnaby Mountain Conservation Area - These bore holes are being drilled to evaluate and assess the geotechnical subsurface soils to determine whether putting the pipeline through the mountain is feasible

Below is an example of equipment used for bore hole drilling:

Drilling Operations - At one of the two borehole locations, with vehicle access, a truck mounted drill rig will be used for drilling - At the second location (where the tree clearing took place), without vehicle access, a helicopter will lower the equipment into the site - A grassy area was selected as a temporary work space and helicopter staging area to bring pieces of the equipment into one of the borehole locations - Trans Mountain is not building a helicopter pad in the Conservation Area and no helicopters will land for the work
