CAMDEN, Nj (CBS) — After a year-and-a-half at the helm of the Delaware River Port Authority, Pennsylvania Governor Tom Corbett announced on Wednesday that he is stepping down later this month.

Corbett put himself in as chairman, in part, to get control of an agency awash in controversy over excessive perks to employees and spending away from its core mission.

“He believes that the board has accomplished that goal,” says Corbett’s press secretary Kevin Harley. “So now he believes it’s time to step off and let others run the board.

One of Corbett’s appointees to the bi-state panel, Jefferson Health System Executive Vice President David Simon, is likely to succeed the Governor as board chairman, with former Delaware County Council chair Andrew Reilly taking the open board seat.

The authority is fine tuning reforms within the agency — with that work expected to be completed by the end of the year.
