A former Mount Vernon official pleaded guilty Wednesday to taking bribes from a mob-tied trash hauling business that overcharged the city.

Former Department of Public Works supervisor James Castaldo admitted that he allowed A and D Carting, which has offices on Saw Mill River Road in Yonkers, to overstate the amount of work it performed between 2002 and 2006.

Castaldo said he took thousands of dollars in bribes while A and D, which prosecutors claim is run by the Genovese crime family, ripped off the city to the tune of $1.25 million.The investigation started last October when the FBI raided City Hall as former Mayor Ernie Davis was seeking re-election. Authorities later issued subpoenas to a number of public servants, followed by indictments in April. Those indictments claimed alleged Genovese members Albert Tranquillo and Michael Pizzolongo were behind the trash scheme.

Castaldo faces up to 30 years behind bars for his role in the carting overcharges.

Neither Davis or his successor, Mayor Clinton Young, were available to comment on the issue.

Meanwhile, Mount Vernon's comptroller says new audits are under way, including investigations into the whereabouts of missing equipment, at City Hall.
