At the moment, Perciasepe is the acting administrator, keeping the top job warm for Obama nominee Gina McCarthy. Perciasepe, 62, has been a respected figure in the world of national environmental policy for nearly four decades. The EPA deputy administrator's career began in Baltimore, where he worked in the city's planning department. He later moved to the Maryland state environmental program and worked his way up to secretary. He was the first chairman of the Northeast Ozone Transport Commission and sat on the board of the Chesapeake Bay Trust. During the Clinton administration, Perciasepe emerged as a key EPA utility player. He first served as assistant administrator in the water-pollution office and later headed the air-pollution and radiation program. His work in the air-pollution office is likely to be especially key during this term, as EPA prepares to roll out controversial global-warming regulations on coal-fired power plants. Before joining the Obama administration, Perciasepe spent five years as the chief operating officer for the National Audubon Society. In 2008, Obama's appointment of Perciasepe to the No. 2 spot at EPA met with kudos from the business community as well as from green activists. Perciasepe, who grew up in New York, holds a bachelor's degree from Cornell University and a master's from Syracuse University.
