Update 5/25: We've updated this post to emphasize that the effects of the dispersants aren't clear.
In a conference call with journalists on Monday, EPA administrator Lisa Jackson said the federal government is asking BP to "significantly scale back" its use of dispersants on the Gulf oil spill. Jackson said the agency was "not satisfied" with the company's response, in which BP argued that despite an EPA order to select and switch to a less toxic dispersant, Corexit was the best option available. (Using dispersants is always a tradeoff, and Corexit has long been on the list of products previously approved for use on oil spills.)
