MARSHALL — About 100 miles east of the site where the Enbridge Inc. pipeline recently ruptured, company officials in December 2009 found an anomaly in the same line that led them to reduce the pressure there by 90 percent, according to a company document.

After excavating the site, the company discovered a dent with minor metal loss, according to the report made available to the Kalamazoo Gazette.

The company determined the anomaly required a 60-day remedy, which, based on the time period, means there is at least 80 percent metal loss in the pipe, according to federal regulations.

No repairs have been performed on the pipe in that location and the company was continuing to operate there at 90 percent lower pressure until the oil spill in Marshall Township, which sent 1 million gallons of crude into the Kalamazoo River.

"In-line tests performed in 2007 and 2009 on pipeline 6B found 329 defects requiring repairs within 180 days, which, according to regulations, means there is at least 50 percent metal loss in the pipe."

Rhetorical question of the day:

:( - I wonder where the steel that these pipes are made from came from???

4. those pipelines

were built before 1965, so the steel was american milled, but the coating back then was not as good as the coating today.

5. 1965... that is worthy of much more regular inspection..
