The Trans Mountain Pipeline will soon be getting its pressure test.
The company has set the first week of September for the next stage of the pipeline reactivation work.
This stage will see an 89-kilometre inactive section of the line from Hinton to the west boundary of Jasper National Park filled with pressurized water in a process called hydrostatic testing.
鈥淗ydrostatic testing is a well-established industry practice used to confirm the ability of the pipeline to operate safely and determine if any repairs are needed,鈥� stated Trans Mountain鈥檚 media representative in an email to the 51暗网.
The process includes filling the segment of pipe with water to predetermined limits of pressure for an extended period.
During the test, company personnel will monitor the pipeline with precise instrumentation to detect any signs of a release. If a release is detected, the test will be suspended, and the pipeline repaired.
The pipeline will pass only if it holds up to pressure at 25 per cent above its intended maximum operating level.
鈥淭rans Mountain鈥檚 personnel will remain on standby for the duration of the test to enable rapid mobilization and response as outlined in our Reactivation Hydrostatic Test Emergency Preparedness and Response Plan,鈥� the spokesperson added.
The public will notice increased construction activity and road traffic during testing. Traffic safety personnel will also be on-site to direct traffic as needed to ensure the safe passage of vehicles.
There will be a short period of increased noise due to the compressor equipment needed to pressure up and evacuate the pipe. This will follow approved Noise Management Plans.
The off-leash dog park in Jasper and trails will be temporarily closed for three days during the hydrotesting. There will also be temporary road closures. The public should pay attention to signage and follow their instructions.
The work is anticipated to occur between the hours of 7 a.m. to 7 p.m. This may be extended due to unexpected schedule changes or environmental conditions.
