CORRECTED COPY UPDATING EVENTS ASSOCIATED WITH PIPELINE RUPTURE

NTSB RELEASES PHOTOS OF PIPELINE OIL SPILL IN MICHIGAN

 

 

 

************************************************************

 

 

The National Transportation Safety Board today released the

following photographs of the pipeline that ruptured and spilled oil

into a river last week in Marshall, Michigan.

 

On the evening of Sunday, July 25th, a 30-inch crude oil pipeline,

operated by Enbridge Energy Partners/Pipeline, experienced multiple

low pressure alarms near the Marshall City Pump station during a

planned shutdown.  By 11:45am (EDT) the following morning Enbridge

employees confirmed an oil leak extending into nearby Talmadge creek, a

tributary to the Kalamazoo River.

 

Two sections of the pipe, 23 feet, 4-inches and another 26 feet, 10-inches,

have arrived at the NTSB for further examination.

 

The photographs show the length of the fracture which extends approximately 6

1/2 feet longitudinally with the widest portion of the opening measuring 4

1/2-inches.  The fracture was located approximately 25 feet from the upstream

joint in a 40 foot section of 30-inch pipe.

The NTSB's investigation continues.
