Observation 2 - Oversight of 3rd Party Excavation for Watermain Installation

Date & time of visit: 2022-05-02 07:30

Discipline: Damage Prevention




CER IO arrived at site at 7:30am (Pacific Time) and attended the safety meeting led by the Trans Mountain (TM) Pipeline Inspector who went through the Safety Meeting for Ground Disturbance/Proximity Installation and Pipeline Protection Inspection Security Checklist and had everyone present sign the document (i.e., prime contractor, hydrovac personnel and CER):

The 3rd party construction project being observed was the installation of a watermain on top and across the TM pipeline along Chilliwack River Road, with isolation valves to be installed 1.5m from either side of the pipe to allow the waterline to be shut off and lifted if work on the TM oil pipeline is required in the future. CER IO requested reason the waterline was going over the TM pipeline rather than under, where it was explained that (1) the watermain needed to be maintained at a certain elevation and (2) that two isolation valves were to be installed 1.5m away from the pipe to allow TM to access its pipeline if it needs to inspect the pipe or work on it - TM would have the City shut the water off at the isolation valves and lift the waterline out. The following was observed:  The CER IOs reviewed the following documentation with respect to the ductile iron watermain facility installation:

Date & time of visit: 2022-05-03 09:30

Discipline: Damage Prevention




Site visit of location of recent DPR contravention in Abbotsford, BC:

IOs accompanied Trans Mountain representatives to the site of a recent damage to pipe which was discovered by the pipeline company in April 2022 in Abbotsford. Upon arrival at the site, CER IOs observed the following:

Company representatives explained that the pipeline damage was assessed upon discovery, repaired accordingly and backfilled. They have followed up with the parties involved and expect the final submission of the report to be completed within the deadline.

Company representatives also shared concerns with crop changes in the area and, in particular, the new crop of hops which grow high thus impeding the view for aerial patrols and requiring the installation of posts. Changes in lessees have also created challenges recently but the company continues to monitor the area. 

Site visit of location of previous DPR contravention and active developments on Cottonwood Avenue in Coquitlam, BC:

IOs accompanied Trans Mountain representatives along Cottonwood Avenue in Coquitlam, BC where previous DPR contraventions events had taken place in 2021 during disconnection of services in preparation for construction of a new housing development at the corner of Cottonwood Avenue and Fairview Street.

The IOs observed the following: Trans Mountain explained that this area is patrolled by air twice a week (weather permitting) as well as ground patrols conducted also twice a week. The Pipeline Inspector added that he also walks or drives on Cottonwood Avenue every workday.

Trans Mountain also informed the CER IOs that some of the developments will eventually require to be connected to services such as water which will involve the installation of underground facilities to be installed across the pipeline.

Trans Mountain further added that these large housing development projects underway have created communication difficulties between the developers and various contractors undertaking the work. CER IOs noted Trans Mountain's efforts in engaging with the developers and other 3rd parties involved to date. Continued engagement with Trans Mountain will be considered to follow the progress made on the construction projects progress and engage the appropriate stakeholder as required.
