Enbridge Inc. will resume shipments this Friday through Line 6A, which was shut down after it ruptured in a Chicago suburb last week.
The company said Wednesday that it has agreed with its regulator, the Pipeline and Hazardous Materials Safety Administration, to resume crude shipments through the line.
"We were both comfortable with the line restarting on Friday," said Enbridge spokesman Glenn Herchak. "Once the line restarts, we will be returning to normal operations prior to the line going down."
U.S. federal investigators said the problem with Line 6A, which is capable of 670,000 barrels per day of crude throughput, and serves as a critical feed line to several Midwestern refineries, did not appear to stem from corrosion or other maintenance problems that have been figured in a separate Enbridge spill in Michigan in July.
The Illinois stretch of pipe had been inspected in 2000, 2004, 2006 and 2008, Enbridge said Wednesday, and no problems were detected with it.
Line 6A line burst beneath a road in Romeoville, Ill., where it was situated in a right-of-way that was crowded with rocks and several other pipes, including a water line that also broke. Some officials have said the rocks could be to blame for the spill, which released 6,100 barrels of crude, most of which were vacuumed up.Report Typo/Error
