ExxonMobil Corp. violated federal safety regulations while operating the Pegasus pipeline that dumped about 5,000 barrels of oil in a Mayflower, Ark., neighborhood in March and should pay more than $2.6 million in penalties, a federal regulator determined.
The U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA), in a notice issued Nov. 6, claims ExxonMobil, and its ExxonMobil Pipeline Co., did not pay attention to known problems with pipeline integrity in 1991, 2005 and 2006.
