HARRISBURG — The budget-threatened Joseph Priestley House, in Northumberland, and R.B. Winter State Park, near Mifflinburg, will be open today, even though Pennsylvania begins its fiscal year without a spending plan.

Both sites have faced the possibility of closure as the state Historical and Museum Commission and the Bureau of State Parks struggle to make cuts in their budgets.

Pennsylvania lawmakers, weighing program cuts against tax increases, have missed their deadline for passing the state spending plan for the seventh consecutive year under Gov. Ed Rendell.

But for now, the Priestley House, and R.B. Winter State Park — one of three dozen state parks that the Department of Conservation and Natural Resources has suggested closing as it faces cutbacks in several 2009-2010 budget proposals — will remain open.

“Until the budget is passed, things will continue as they have,” said Christina Novak, a spokeswoman for DCNR, which oversees the Bureau of State Parks.

“Unless things drag on for a long time, we’ll all continue to work. Our parks will be open for the Fourth of July.”

Kirk Wilson, of the Historical and Museum Commission, agreed.

“Nothing will change until there is a budget,” he said.

The Main Street and Elm Street programs, sponsored by the state Department of Community and Economic Development, will also continue, even though they would be eliminated under Rendell’s proposed budget.

“I’ll be here in the morning,” Season Hain, Elm Street manager for Mifflinburg, said Tuesday.
