Oklahoma Air Permitting Issues

In Oklahoma, permits are not required for facilities with actual emissions less than 5 tons of VOCs per year. Facilities with emissions over 5 tons must obtain a minor source permit from the state. Oklahoma does have a Title V permit program in place. Sources with the potential to emit more than 100 tons of VOC per year, or 10 tons of one hazardous air pollutant (HAP) or 25 tons of a combination of HAPs are required to apply for a Title V permit. The state's program does contain provisions for a synthetic minor designation. Synthetic minors are those facilities that agree to federally enforceable limits that restrict their potential to emit to less than the major source threshold.
