HARRISBURG — The country’s largest full-time Legislature will soon have to decide where it will get the money to pay thousands of employees and other costs as its surplus, once more than $200 million, is rapidly dwindling amid Pennsylvania’s budget crisis.

The four caucuses’ funds are expected to be depleted in the coming weeks or months, thanks in part to the partisan budget standoff now in its second month. Illinois is the only other state without a budget or temporary spending plan in place.

Democrats, led by Gov. Tom Wolf, are locked in slow-moving negotiations with the Republicans who control both chambers.

“We have enough to reach early September,” said House Democratic spokesman Bill Patton. “Several options are under consideration but we have not decided on a particular course of action.”

The Treasury Department has agreed to continue paying employees if legislative leaders ask for it, said spokesman Scott Sloat.

“Throughout the impasse we’ve been paying all employees of all branches,” Sloat said. “The legislative branch has been getting paid through the surplus that they have, and the Treasury’s position is that all employees, regardless of which branch they are, who work, should be paid. If the Treasury is presented with payroll requests from the proper folks in the legislative branch, the intention is to pay them.”

Senate Clerk Donetta D’Innocenzo described the chamber’s financial situation as “a fluid situation. It’s changing daily.”

She said the Senate expects that its money, now at or below $15 million, will last through September.

House Republican spokesman Steve Miskin said his caucus was considering options that include taking out a line of credit. He said Wolf’s veto of the entire budget earlier this summer has raised questions about whether Treasury can transfer money, and whether the state employees that are currently being paid are authorized to run programs in the absence of a budget.

Pennsylvania has 253 state lawmakers, and its permanent staff of nearly 3,000 ranked first in the country as of 2009.
