From the Sierra Club:
Three Major Spills in One Week -- Arkansas, Ontario, and now, Texas.
San Francisco, CA -- Earlier today, it was discovered that Shell's West Columbia pipeline spilled crude oil into a Texas waterway that leads to the Gulf of Mexico, joining incidents in Arkansas and Ontario, Canada, to close out a week of oil transportation accidents.
In response, Michael Brune, Sierra Club executive director, released the following statement:
“In these three latest oil disasters, oil companies have proven they are irresponsible. In Ontario, the company said it spilled four barrels when it had actually spilled 400. In Arkansas, Exxon learned about the spill from a homeowner but kept pumping tar sands crude into the neighborhood for 45 minutes, and is bullying reporters who want to tell the public what's going on. Today, in Texas, a major oil spill came to light that Shell had been denying for days.
"Transporting toxic crude oil -- and tar sands in particular -- is inherently dangerous, more so because oil companies care about profit, not public safety. This is why Keystone XL, at nine times the size of the Arkansas Pegasus pipeline, must never be build.”
