UPDATE 1-Treasury's Mnuchin: Hurricane Harvey could impact debt ceiling deadline

WASHINGTON, Aug 31 (Reuters) - U.S. Treasury Secretary Steven Mnuchin said on Thursday that the impact of Hurricane Harvey could bring forward the deadline by which the nation's debt ceiling needs to be raised and that he is open to the borrowing cap being dealt with as part of a wider bill. "We obviously have now the hurricane spending, which is an issue. So that's going to have some impact on our September spending," Mnuchin said in a interview with broadcaster CNBC, adding that it could affect the debt ceiling deadline by a couple of days.

He also said projections may move around once the Treasury receives corporate tax receipts on Sept. 15.

The U.S. government has a statutory limit on how much money it can borrow to cover the budget deficit that results from Washington spending more than it collects in taxes. Only Congress can raise that limit.

Mnuchin told lawmakers in July they needed to raise the debt limit by Sept 29, otherwise the U.S. government might not have enough money to pay all its bills.

The Treasury chief appeared open to the possibility of raising the debt ceiling as part of a larger bill in Congress.

Asked if he would support the debt ceiling being tied to a bill on Hurricane Harvey relief in Congress, he said while his preferance was a 'clean' increase "at the end of the day, its all about raising it. If they want to raise it and attach it to something, that's fine with me as well."

Mnuchin said discussions on the debt cap were being held with the leadership of both the Republicans and Democrats and said: "I am very confident we will get this raised."
