12 How the Test is Performed (con t) De-pressurize the line Drain the water from the system If any integrity issues are found: They are corrected as soon as possible The hydrotest is performed again Any re-testing will be performed as soon as possible, during the same hours Resume normal natural gas service 12

13 Safety During the Test Safety is our #1 priority Performed 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 13
