Will the EPA treat milk as a hazardous substance?

The story from the Omaha World-Herald is here.

Imagine treating milk the same as the toxic sludge now washing up on Gulf Coast beaches.
It may sound absurd, but some dairy producers are worried that it could happen under U.S. Environmental Protection Agency regulations intended to prevent oil spills from polluting waterways.
“It's another example of an environmental law where it's really meant to target heavy industry but actually has some farm implications,” said Chris Galen, spokesman for the National Milk Producers Federation.
The EPA program in question falls under the Clean Water Act and requires owners of large oil storage tanks to develop plans to prevent and handle any spills.
Milk contains a certain percentage of animal fat, which is considered a non-petroleum oil, and therefore bulk milk storage tanks near waterways could be subject to the regulations.
Farm groups say there's no reason to put milk under the same heading as oil — who's ever seen a milk-covered pelican struggle to fly? After all, milk is more than 80 percent water, said Stacey Fletcher, spokeswoman for the Nebraska State Dairy Association.
“That's very concerning, that we would ever find milk and oil in the same category,” she said. . . .
