Katrina == 65% of an Exxon Valdez?

Green Car Congress has an interesting post, Katrina Spilled 7.2+ Million Gallons of Oil:

In its rampage through Louisiana, Hurricane Katrina caused some 44 currently known oil spills that dumped more than 7.2 million gallons of oil onto land and into water, primarily the Mississippi River, according to reports from the US Coast Guard.

That amount is equivalent to approximately 65% of the spill from the Exxon Valdez.

Somehow I don't think we'll be hearing that much about this. Somehow I don't think Rove will allocate that much money towards assessing or mitigating this part of the disaster. Well, maybe a few fat Halliburton contracts, but nothing in the press...
