On Friday, March 29, 2013 at approximately 2:45 p.m, the Exxon Mobil Pegasus pipeline, which brings Canadian crude oil from Illinois to Texas, ruptured, leaking at least 80,000 gallons of oil into the Central Arkansas town of Mayflower (a small town about 20 miles from Little Rock, Arkansas). The leak flowed for about 45 minutes before they could stop the leak.
The pipeline developed a leak and oil fluids spread across gardens, residential streets...entering streams and drainage ditches running under Hwy 365 and Interstate 40. Pipeline crosses several waterways in the area and could potentially present a threat to water supplies. Forty homes have been evacuated and that number continues to rise.
According to an article in Reuters on Sunday, March 31, 2013 (5:07 p.m.est) Exxon's Pegasus pipeline, which can carry more than 90,000 barrels per day (bpd) of crude from Pakota, Illinois to Nederland, Texas, was shut after the leak was discovered late Friday afternoon in a subdivision near the town of Mayflower.
Exxon said it staged the response to handle 10,000 barrels of oil "to ensure adequate resources are in place."
Fifteen vacuum trucks remained on the scene for cleanup, and 33 storage tanks were deployed to temporarily store the oil.
The pipeline was carrying Canadian Wabasca Heavy crude at the time of the leak. An oil spill of more than 1,000 barrels into a Wisconsin field from an Enbridge pipeline last summer kept that line shuttered for around 11 days.
The Arkansas spill drew fast reaction from opponents of the 800,000 bpd Keystone XL pipeline, which would carry heavy crude from Canada's tar sands to the U.S. Gulf Coast refining center. The U.S. Environmental Protection Agency had categorized the rupture as a "major spill."
Environmentalists have expressed concerns about the impact of developing the oil sands and say the crude is more corrosive to pipelines than conventional oil. On Wednesday, a train carrying Canadian crude derailed in Minnesota, spilling 15,000 gallons of oil.
"Whether it's the proposed Keystone XL pipeline, or ... (the) mess in Arkansas, Americans are realizing that transporting large amounts of this corrosive and polluting fuel is a bad deal for American taxpayers and for our environment," said Representative Ed Markey, a Massachusetts Democrat.
There is more information on this unfortunate incident and will try to update you the best I can.
