GE Aviation Expanding its Engine Testing Ability

Ohio EPA Director Scott Nally Touring Plant Today

Ohio EPA Director Scott Nally and officials from Southwest Regional Air Quality today toured GE Aviation in Evendale to view a facility expansion that was aided by a prompt review of GE Aviation’s air permit application.

Ohio EPA and Southwest Ohio Air Quality Agency (SWOAQA) staff reviewed and issued the required permit to GE Aviation in 69 days. GE Aviation designs and tests airplane engines at its Evendale facility. The company will install two test cells, one for research and development of new jet engine components while the second will test production marine and industrial jet engines.

“This is an example of how Ohio EPA and the SWOAQA work with stakeholders to provide the most efficient and effective service possible,” Ohio EPA Director Scott Nally said. “We need to always make sure we are being environmentally protective. By being proactive, we can be more efficient and help businesses grow in our state.”

“The Southwest Ohio Air Quality Agency utilized a new, team-based approach in processing this complex permit application allowing Ohio EPA to issue the final permit in a more timely manner,” said Brad Miller, assistant director of the Southwest Ohio Air Quality Agency.

“With the dramatic launch of the new GE9X engine for the Boeing 777X, GE Aviation has entered an era of unprecedented engine development and growth,” said Kevin Kanter, manager of Design and System Integration Engineering at GE Aviation. “As part of this growth, GE Aviation is investing over $100M into the local economy with the building of two new advanced test cells. These test cells require new air permits to operate and perform valuable testing for engine certification. With the excellent support and planning from the Ohio EPA this plan has become a reality. Timely delivery of this permit will allow the hundreds of jobs for the construction and facility operation to remain in Ohio. And the Ohio EPA efforts further help GE Aviation to enhance its world headquarters in Greater Cincinnati.”

Working together, Ohio EPA and SWOAQA created a new system for developing this air permit. The agencies established a team of air permit writers to review GE’s permit applications and drew upon the strengths and experience of each member to draft sections of the permits in parallel, rather than having one person review the entire permit.

A complicated air permit such as this would typically take six months to a year or more to issue. The short turn-around allowed GE Aviation to meet its aggressive schedule for constructing the new test cells. Ohio EPA and SOAQA also acted as liaisons to U.S. EPA Region V to ensure that it was satisfied with the draft permit.


The Ohio Environmental Protection Agency was created in 1972 to consolidate efforts to protect and improve air quality, water quality and waste management in Ohio. Since then, air pollutants dropped by as much as 90 percent; large rivers meeting standards improved from 21 percent to 89 percent; and hundreds of polluting, open dumps were replaced with engineered landfills and an increased emphasis on waste reduction and recycling.
