Reply #4: A letter from Ed Markey did this, but atleast the EPA is getting its head out from its ass.

"On Monday, Rep. Edward J. Markey (D-Mass.) sent a letter to EPA Administrator Lisa P. Jackson questioning the approach, given that Britain banned some formulations of the dispersant Corexit more than a decade ago.

In the letter, Markey warned, "The release of hundreds of thousands of gallons of chemicals into the Gulf of Mexico could be an unprecedented, large and aggressive experiment on our oceans, and requires careful oversight by the Environmental Protection Agency (EPA) and other appropriate federal agencies."

The EPA has a list of its approved dispersants on its Web site.
On Thursday, Markey commended the EPA, saying, "The effect of long-term use of dispersants on the marine ecosystem has not been extensively studied, and we need to act with the utmost of caution.""
