Fill the line with waterPressurize the system

Normal operating pressure is 722 PSI Test pressure is up to 1,444 PSI• Relatively short duration (approx. 30 minutes)

Reduce to intermediate pressure at 1,108 PSI•Maintain for 8 hours

How the Test is Performed

De-pressurize the lineDrain the water from the systemIf any integrity issues are found:

They are corrected as soon as possible The hydrotest is performed again• Any re-testing must be performed within the

prescribed test window timeframeResume normal natural gas service

How the Test is Performed (con’t)

13

Safety is our #1 priorityPerformed extensive test

preparations, including an inspection of the entire system

Any pipe anomalies will be repaired in advance of conducting the hydrotest

For the duration of the high pressure test, as a safety consideration, we plan to isolate sections of the pipeline route from people and traffic
