HARRISBURG — With budget season approaching, Gov. Tom Wolf’s administration is developing a plan to help deal with aging school buildings plagued by environmental problems, including lead paint and asbestos insulation, his office said.

Wolf must deliver a budget proposal to the Legislature on Feb. 4, and lawmakers who are pressing for state aid to address what they call a massive and growing problem have asked the Democratic governor to include money in the spending package.

Wolf has discussed the need in the past, saying that a sprawling infrastructure plan he floated last year could have been a source of help. But that plan — a $4.5 billion infrastructure proposal to be paid off by imposing a tax on Marcellus Shale natural gas production — never saw a vote in the Republican-controlled Legislature, and Wolf’s office said he will try a new strategy to deal with deteriorating school buildings.

The matter has been particularly visible recently in Philadelphia, where the district closed six schools in recent months to clean up asbestos.
