$300 million

Of course, a lot of money went into Gov. Tom Corbett’s campaign to help make that tax go away:

Since 2009, Pennsylvania has lost more than $300 million in revenue by not passing a tax on gas production from Marcellus Shale wells, according to The Pennsylvania Budget and Policy Center.

The Harrisburg-based tax and budget policy research nonprofit said its drilling tax ticker breached the benchmark on Monday, representing lost revenue Pennsylvania could be using to reduce cuts to state funding in education, health care and social services.

The money also could be used to fund environmental protection and conservation, and to mitigate impacts of drilling on local communities, the center said.
