Oil & gas industry spills happen "all the time"

CBS News collected reported incidents for 2010 at wells and pipelines from three federal agencies and 23 of 33 oil and gas producing states. Not counting the BP disaster, we found at least 6,500 spills, leaks, fires or explosions nationwide - that's 18 a day. Overall, at least 34 million gallons of crude oil and other potentially toxic chemicals were spilled. That's triple the size of the 1989 Exxon Valdez spill.
