Pennsylvania Governor Tom Wolf on Thursday proposed a tax on extracting natural gas to pay for his plan to spend $4.5 billion over the next four years to improve the state's infrastructure.
The state legislature, however, has refused to approve the tax over the past couple of years.
Wolf said Pennsylvania is the only state in the country without a severance tax on extracting natural gas.
Pennsylvania is the second biggest gas-producing state behind Texas. The state produces about 18 billion cubic feet per day (bcfd) from the Marcellus and Utica shale basins, which is a little over 20 percent of nation's total gas production.
