Pipeline beneath Straits of Mackinac passes pressure tests
June 11, 2017
MACKINAW CITY, Mich. (AP) — Enbridge says an oil pipeline beneath the Straits of Mackinac in northern Michigan has passed pressure tests required in a Justice Department agreement following a 2010 oil spill in southwestern Michigan.
The tests took place Saturday on one pipeline that's part of Line 5.
The Canadian company pumped the line's west segment with water and kept pressure high for 8 hours. Enbridge officials told reporters in a conference call Monday that the line is fit for service and no leaks were found.
A second pipeline, called the east segment, will be tested soon.
