On March 2, 2017 Ohio EPA announced it is now accepting general permit applications for oil and natural gas mid-stream compressor station spark ignited and compression ignited engines as well as other compressor station equipment. Ohio EPA lists five lean burn and five rich burn size choices for spark-ignited engines. Two size choices are available for diesel compression ignition engines.
Previously, air emissions from these common pieces of equipment were subject to the longer case-by-case permit process. By contrast, applications for general permits follow a template. These general permits allow the Agency to ensure it protects the environment while freeing up valuable staff resources to work on other complex permit issues.
General permit applicants are required to demonstrate that the equipment qualifies for a general permit, and agree to meet pre-defined permit terms including installation and/or operating requirements, monitoring, record-keeping and reporting.
All of these general permits require the installation of state-of-the-art equipment or methods to control air emissions that meet or exceed federal standards.
