Business as usual as Spectra replaces pipeline

Spectra work crews are ripping it up through Chilliwack's busiest intersection.



n 2014, Spectra Energy will be replacing a 600-metre section of 30-inch diameter natural gas pipeline in Chilliwack, B.C. The replacement begins east of the commercial area adjacent to the railway, to Chilliwack Mall.


The replacement will meet the Canadian Standards Association (CSA) standard for oil and gas pipeline systems as required by  the CSA standard and the National Energy Board.

Under Canadian standards, there are different class designations for pipelines based on the number and types of buildings and dwellings nearby. As development and population growth occurs near pipelines, the class designation may change and the pipeline may need replacement.


The CSA standard requires that assessments consider 200 metres (m) on either side of the pipeline and over its length. Because of changes in area development and population growth, we will be replacing and upgrading the pipeline in that area to a higher classification standard. The diameter, capacity and location of the pipeline will remain the same.

Details of the Project Scope include:
Replacement of 600 m of existing pipeline within the existing right-of-way (ROW).
Temporary workspace will be required at locations adjacent to the pipeline ROW.
Existing roads will be used for access to the ROW and work locations.
Construction will likely occur between June and October 2014.
