TRENTON - Trenton Mayor Tony Mack has scrapped plans to furlough 600 city workers following objections from state environmental officials and a Superior Court judge.

Mack announced earlier this month that the workers would have to take 13 unpaid days off between April and June in an effort to help bridge an $18.5 million budget gap.

The proposal would have forced city hall, the municipal court and other offices to close on furlough days. But the mayor scuttled that plan Friday.

The decision came after the Department of Environmental Protection said water filtration plants like Trenton's must have a full-time licensed operator and have licensed staff present at all times.

And Mercer County Assignment Judge Linda Feinberg said the city needed her permission to alter its court hours.
