Narrative
At approximately 11:42 october 6, 2011 the scada system in magellan's operations control center indicted a sharp drop in pressure and an increase in flow rate on the #6-10" pipeline between topeka and kansas city. Magellan personnel executed a code red emergency shutdown of the line in accordance with magellan's o&m procedures and notified qualified field personnel to investigate. Subsequent investigation discovered that an excavating contractor had dented the line in several places and punctured it with a tooth of a front end loader while excavating a pond. The excavator did not place a one-call with the kansas one call agency. Magellan personnel immediately began controlling the released product and repaired the line with a segment of new, pretested pipe in accordance with PHMSA regulations and company procedures. The released product was recovered and 4708 cubic yards of effected soil were remediated per company and state requirements.
