The order keeps Exxon from restarting the pipeline until the Pipeline and Hazardous Material Safety Administration is comfortable with repairs.
Investigations are still trying to pinpoint exactly what caused the rupture. According to the corrective order, the break in the Pegasus pipeline sent anywhere from 3,500 to 5,000 barrels of crude oil spilling onto the streets and surrounding neighborhoods of Mayflower.
Preliminary federal findings show the rupture occurred around 3:15 p.m. Friday and reported the failure to DOT by 4 p.m. The report says Exxon learned of the rupture after noticing a drop in pressure. According to the report, Exxon shut down valves on each side of the rupture in roughly 15 minutes.
The initial report also confirms local reports that none of the oil has impacted Lake Conway.
The Pipeline and Hazardous Material Safety Administration findings also show Exxon ran tests around the failure site on the pipeline in February. Findings from those tests have not yet been returned.
