PITTSBURGH — Gov. Tom Corbett’s much-anticipated plan to regulate and harness Pennsylvania’s booming natural gas industry would let counties impose an impact fee on the drilling to help pay for the cost to regulate it and fix any damage it causes to the environment.

The impact-fee proposal is part of a wider plan being released publicly by Corbett later today.

According to a briefing sheet from the Corbett administration, the plan would allow an impact fee of no more than $40,000 per well in a well’s first year. After that, the fee amount would decline, to $30,000 in the second year, $20,000 in the third year and $10,000 in the fourth through tenth years of production.

It estimates that it would generate up to $120 million in the first full year, and up to $195 million by the sixth year.

Most of the money would remain in drilling communities for a wide range of uses, while 25 percent would go to the state for environmental protection, road and bridge improvements, health studies, emergency management, pipeline inspection and the state fire commissioner.

The Legislature has debated whether to impose a tax or a fee on the natural gas industry, since it arrived in earnest in 2008 to tap into the Marcellus Shale natural gas formation, considered the nation’s largest-known natural gas reservoir.
