It has been more than a month since the Exxon Mobil tar sands oil spill in Mayflower, Arkansas and residents and investigators are still waiting for answers to basic questions about the disaster. Katherine Bagley at InsideClimate News lists the unanswered questions:
When did the pipeline begin leaking? When and how did the oil company find out about it? How quickly did the company act? How much oil spilled from the pipeline's 22-foot-long gash? And what condition was the line in before it ruptured?
As with most cover-ups, a key point of debate will be what Exxon knew and when. On that point, be sure to see the 911 transcripts InsideClimate News has compiled that find discrepancies in Exxon's statements about when they learned the pipeline was leaking.
