Listening to the news, you might have thought that BP was picking up the tab for this oil spill, but that's only true in a very limited sense. Brad Plumer explains:
Big, wealthy oil companies like BP are usually expected to pay to the cleanup costs themselves. But that still leaves the cost of all the indirect damage to fisheries and wildlife habitats in the area. In that case, under current law, an offshore rig operator is liable for up to $75 million in damages. After that, the federal government picks up the tab, using an oil spill liability trust fund that's paid for by a tiny tax on oil (amounting to one-tenth of 1 percent of the price).
