AUGUSTA, Maine — Ranking Maine lawmakers are being told they are likely to face a new budget gap approaching $600 million.

Associated Press sources in the Legislature and the Baldacci administration say the current working supposition is $575 million — that’s the likely new hole in what now in a pending $6 billion-plus two-year general fund spending blueprint.

Gov. John Baldacci’s budget chief, Ryan Low, was scheduled to address the Appropriations Committee Friday.

Formal action by a state panel to lower current revenue projections is scheduled next week.

The Baldacci budget bill as it stands now seeks to cover an original gap of about $340 million, according to a legislative staff analysis.

The new shortfall would come on top of that.
