On 29th March 2013, An Exxon Mobile underground pipeline ruptured in a Mayflower, Arkansas subdivision. The pipeline, called the Pegasus, leaked for about 45 minutes, according to local sources, and leaked at least 80,000 gallons of oil. Crude oil ran through a subdivision of Mayflower, Ark., about 20 miles north of Little Rock. Twenty-two homes were evacuated. Faulkner County of Arkansas, Judge Allen Dodson issued an emergency declaration following the spill and is involved in coordinating clean-up efforts among federal, state and local agencies and Exxon. 

The 20-inch Pegasus pipeline runs 858 miles from Patoka, Ill. to Nederland, Texas. Exxon Mobil's spokesman had confirmed that the line was carrying Wabasca Heavy crude from western Canada when it ruptured. Wabasca Heavy crude oil is a type of dilbit which contains bitumen, a type of crude oil that's heavier than most conventional crude oil, therefore it can be much more difficult to clean up when it spills into water. A 2010 spill in Michigan, which released a million gallons of dilbit in the Kalamazoo Riverand has cost pipeline operator Enbridge more than $820 million, continues to challenge scientists and regulators as they work on removing submerged oil from the riverbed.
