Federal pipeline safety officials have issued a corrective action order to ExxonMobil after one of the company's pipelines ruptured last week in central Arkansas.
The Pipeline and Hazardous Materials Safety Administration issued the order Tuesday 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 until the agency is satisfied with repairs and is confident that all immediate safety concerns have been addressed. The order says about 3,500 to 5,000 barrels of oil spilled. Investigators are still working to figure out what caused the pipeline to rupture.
