Narrative
A company employee was driving by the location of the pipe failure, when he noticed dead vegetation and product pooling on the ground surface. Company personal responded with support from contractors to excavate the area, collect and properly store for disposal, all affected ground water. The pipeline was down already per the pumping schedule. Line pressure was reduced during exploratory excavation work. A crack was found on the outside of a 90� bend during a low pressure test. The pipeline was drained via elevation drain up and the defective bend was replaced with a new hydro-statically tested bend. All installation welds were non-destructively tested. Before the line was restarted, pressure controlling devices were set to 80% of the highest pressure recorded during the last 60 days prior to discovery of the release. The defective bend was sent to kiefner and associates for metallurgical analysis. The metallurgical report from kiefner and associates concludes that there were four contributing factors that led to the crack found on the pipe bend. These contributing factors, in no particular order of importance, are two small notches in the pipe at the leak site, stress on the bend likely related to the installation of the pipe, hardness of the metal at the site of the bend likely relating to the manufacturing process for the bend, and slight corrosion due to a separation of the coating which allowed water to come in contact with the bend. The kiefner report recommends that wolverine further investigate the hardness of two more bends on this 1976 pipe segment to determine the hardness of the pipe at these bend sites. Wolverine is currently planning to excavate two of these bends on this pipe segment. Approximately 616 tons of soil were removed and properly disposed of from the source area.
