Former Utah Governor Michael Leavitt (R) was sworn in in early November as the 10th administrator of the Environmental Protection Agency. Marianne Horinko, who had been acting EPA administrator, will return to her previous post as EPA assistant administrator of the Office of Solid Waste and Emergency Response. Steve Johnson, currently acting deputy administrator, will stay in that role for the time being, but it is unclear whether Leavitt will retain him in that capacity.
