Final GP-5 Air Quality General Permit For Gas Compressors Published By DEP

The Department of Environmental Protection published notice in the January 17 PA Bulletin of the final modifications to the Air Quality General Plan Approval for Natural Gas Compression and Processing Facilities (BAQ-GPA/GP-5) which included--

— Removal of the 100,000-ton per year greenhouse gas emissions applicability threshold for the use of GP-5.

— Clarifying that the Applicability/Scope of GP-5 applies to all types of natural gas-fired compressors.

— Addition of an annual compliance certification requirement signed by a Responsible Official.

— Clarifying that EPA Method 323 is the appropriate test method to determine formaldehyde emissions.

— Deletion of references to 40 CFR Part 63, Subpart HH (relating to National emission standards for hazardous air pollutants from oil and natural gas production facilities).

The draft changes to GP-5 were published for comment in the November 15 PA Bulletin.

A revised GP-5 will presumably be posted on DEP’s Air Quality General Permits webpage.
