Pennsylvania's general fund is on track to be $1.6 billion dollars underwater by the middle of next month.
In the past, the state Treasury has extended lines of credit to help the state keep paying immediate expenses when funds bottom out.
But Treasurer Joe Torsella says that may no longer be fiscally prudent.
The cash balance would have already hit zero this month, if not for a short term, $750 million credit line from the Treasury. The state has to pay that back with interest next week. But the fund is expected to run dry yet again before the end of August.
