While the BP well was still gushing, the Obama administration issued an order that limited the spreading of controversial dispersant chemicals on the Gulf of Mexico's surface. Their use, officials said, should be restricted to "rare cases."

But in reality, federal documents show, the use of dispersants wasn't rare at all.

Despite the order -- and concerns about the environmental effects of the dispersants -- the Coast Guard granted requests to use them 74 times over 54 days, and to use them on the surface and deep underwater at the well site. The Coast Guard approved every request submitted by BP or local Coast Guard commanders in Houma, La., although in some cases it reduced the amount of the chemicals they could use, according to an analysis of the documents prepared by the office of Rep.
