During a Wednesday afternoon conference call announcing the Framework and new guidance, EPA Administrator Lisa Jackson told reporters that she does not "think there will be some expansion to waters that currently people might view as isolated" (and not currently regulated under the Clean Water Act). However, she also noted that it is unclear how many more wetlands or waterways would now be covered, under definitions in the new guidance, adding, "This is not some massive increase as far as we can tell."
The draft guidance is now open for 60 days of public comment, and can be viewed here. The White House Council on Environmental Quality Framework web page is here.
