In January 2016, Gov. Wolf announced his methane reduction strategy for unconventional natural gas drilling operations. This strategy included the development of new and revised permits (GP-5 and GP-5A) for new sources of methane emissions and the development of regulations for existing sources. At that time the Wolf administration estimated that permits for new sources would be ready by the second half of 2016 and the regulations for existing sources would be proposed by early- to mid-2017.
