The Pennsylvania House and Senate approved separate versions of legislation to strengthen environmental rules surrounding drilling in the Marcellus Shale, and to impose a per-well impact fee to fund local infrastructure. The state Senate approved its version of the bill on November 15; the state House approved its version on November 17.

Legislative sources say that a proposal could be agreed to before the end of the year, but differences in the versions still need to be ironed out among both chambers and Pennsylvania Governor Corbett's office.
