HARRISBURG — Efforts to write sweeping bipartisan legislation to update the state’s laws to address its booming natural gas industry and slap a fee on the drilling companies failed to wrap up in time for a vote this week and could go on for another two weeks in the state Senate, a top negotiator said Monday.

Senate President Pro Tempore Joe Scarnati said the hurried effort over the weekend to wrap up the talks did not resolve all the disagreements between Republicans and Democrats and that his fellow Republicans, who control the chamber, wanted more time to review any proposal to ensure they are comfortable with it.

“It is not soup yet to the point that we can put this together,” said Scarnati of Jefferson.

The bill could run dozens of pages long, if not more than 100, to toughen clean water protection laws and penalties for environmental violations, impose an impact fee on wells in the Marcellus Shale formation and distribute the money from the fee.

Scarnati said he will continue working with Democrats. Talks were going well, but some issues still need to be addressed, he said.

The earliest that the Senate could vote on any proposal is the week of Nov. 14, when senators return to session in Harrisburg.

Drilling companies began flocking to Pennsylvania in earnest in 2008 to exploit the gas in the Marcellus Shale formation, the nation’s largest-known natural gas formation. But the drilling companies were largely working under 1980s laws that never envisioned the deep-drilling activity and a high-volume drilling process called hydraulic fracturing, which uses chemicals and produces millions of gallons of often toxic wastewater.

The Legislature has done little to update those laws, leaving it largely to the Department of Environmental Protection to make changes by regulation. Meanwhile, Pennsylvania remains the largest gas drilling state without any kind of tax on the activity, despite efforts by Democrats to press it.
