The industry is dead set against an extraction tax. So are Republican lawmakers, many of whom benefit from the industry's campaign contributions. (Democrats have also received contributions, though far less than Republicans.) The industry does pay impact fees — a levy enacted during the Corbett administration, which sets a fee based on each well drilled, not the volume of gas it produces. Last year, the tax bought in $173 million a year, the lowest amount since the fee was enacted in 2011, and most of it goes to areas where drilling is concentrated.
