LITTLE ROCK, Ark. — Federal pipeline safety officials on Tuesday issued a corrective action order to ExxonMobil Pipeline Co. after one of its pipelines ruptured last week in central Arkansas.
The order from the Pipeline and Hazardous Materials Safety Administration comes after ExxonMobil's Pegasus pipeline ruptured Friday in the small city of Mayflower, about 25 miles northwest of Little Rock.
The order prevents ExxonMobil from restarting operations on the failed segment of the pipeline until the agency is satisfied with repairs and is confident that all immediate safety concerns have been addressed.
Investigators still are working to figure out what caused the pipeline to rupture, but the corrective action says ExxonMobil reversed the system flow of the pipeline in 2006.
