File of workers scrubing crude oil from their boots in the Northwoods subdivision where an ExxonMobil pipeline ruptured in Mayflower

Workers scrub crude oil from their boots in the Northwoods subdivision where an ExxonMobil pipeline ruptured in Mayflower, Arkansas, in this April 1, 2013 file photo. Now, nearly two weeks after the 5,000-barrel spill occurred on Good Friday, a picture has emerged of a giant oil company thrust into a small blue-collar community, intricately managing not just the cleanup of a major spill, but also using its large check book to try to win over the townsfolk and seek to limit the fallout.

Exxon's Pegasus pipeline was shut

after the leak was discovered March 30 in a subdivision

near the town of Mayflower, which spilled thousands of gallons of crude oil in Arkansas. The leak forced the evacuation of 22 homes, and clean up has begun.
