Pennsylvania DEP Proposes Changes to GP-5 Air Permit for Compression, Processing Facilities

On Saturday, November 15th, the Pennsylvania Department of Environmental Protection (DEP) published proposed changes to its General Plan Approval and/or General Operating Permit (BAQ-GPA/GP-5 or General Permit) for Natural Gas Compression and/or Processing Facilities (known as “GP-5”) issued in February 2013.  Operators may apply for coverage under GP-5 to authorize the construction, modification, and/or operation of a natural gas compression and/or a gas processing facility.

Among other proposed changes, DEP has deleted the applicability threshold requirement for greenhouse gases in response to the United States Supreme Court’s Utility Air Regulatory Group (UARG) v. Environmental Protection Agency (EPA) decision issued on June 23, 2014.  DEP also added a requirement to submit an annual compliance certification for GP-5; the annual certification would be due to DEP by March 1 each year.  Public comments on the proposed revisions to GP-5 will be accepted by DEP until January 6, 2015.
