MAYFLOWER, Ark. (KTHV) - More details are now known about the Pegasus Pipeline, which is operated by ExxonMobil andruptured in a Mayflower, Arkansas neighborhood on Friday, March 29.

According to a news articleposted on ExxonMobil's website, the pipeline underwent two significant changes in the last ten years.

One change occurred in 2006, when the pipeline system reversed its motion and began moving crude oil to the Gulf of Mexico. The more recent change came in 2009 when the pipeline increased its capacity by 50 percent (about 30,000 barrels per day).

The Pegasus Pipeline stretches 858 miles from Patoka, Illinois to Nederland, Texas, stretching from the northwest corner or Arkansas to the southeast corner. Maps of the pipeline can be found at the following sites:

Arkansas Gov. Mike Beebe said the Pegasus Pipeline was inspected in February 2013, but results of that inspection had not been returned.

The following news article from 2009 is posted on ExxonMobil's site:

HOUSTON--(BUSINESS WIRE)--Mobil Pipe Line Company, an affiliate of ExxonMobil Pipeline Company, has completed a project that will increase capacity by 50 percent, or about 30,000 barrels per day, of its 858-mile Pegasus Pipeline that operates from Patoka, Illinois to Nederland, Texas.

The expansion project includes the reactivation and enhancement of several pump stations along the pipeline. The additional capacity will enable the transportation of additional Canadian crude from the Midwest to Gulf Coast refineries. Operational enhancements, such as new leak detection technology, were also incorporated to support ExxonMobil Pipeline Company's primary focus on operating its pipelines in a safe and environmentally responsible manner.

"The expansion of the Pegasus Pipeline is another example of how ExxonMobil Pipeline Company is continuing to develop new projects that provide valued services and enhance supply security," said Gary Pruessing, president, ExxonMobil Pipeline Company.

"This expansion project builds upon the success of the Pegasus Pipeline system reversal that began moving Canadian crude shipments to the Gulf Coast in 2006."
