HARRISBURG — Outgoing Gov. Ed Rendell is encountering opposition to his plans for a $1 billion taxpayer-financed bond issue to continue the flow of money to a slew of construction and renovation projects, from prisons and bridges to hospitals and museums.

Auditor General Jack Wagner on Wednesday refused to support it, citing a projected multibillion-dollar deficit the state is facing next year.

Treasurer Rob McCord, who hadn’t decided on Wednesday, sought input from the man who is replacing Rendell in seven weeks, Attorney General Tom Corbett.

Approval from Wagner or McCord — both Democrats, like Rendell — is necessary before the bonds can be sold.

A spokesman for Corbett said the Republican governor-elect needs to review the list of projects before taking a position.

In a letter Wednesday to Corbett, McCord said the amount — $1 billion — is twice as large as the state’s biggest prior “lame duck” bond issuance, in 2002, and said he will weigh Corbett’s position on it along with other factors.

Wagner said approving such a large volume of borrowing is unwise when the state is facing such a large deficit and still has $300 million in construction money to spend.

Rendell and his aides defended the borrowing as necessary to ensure that construction continues on scores of projects that are already under contract.

They said the $300 million will run out by Feb. 1, and that the additional $1 billion would pay for the latest or first installments on scores of projects.

Without the bond issue, money will stop flowing to the projects, work will stop and costly lawsuits could result, Rendell’s chief of staff Steve Crawford warned.

The Rendell administration has fully briefed Corbett’s transition team on the matter, and the borrowing is customary for an outgoing administration to complete so that a new administration has the money it needs on hand to meet the state’s capital obligations, Crawford said.
