OKLAHOMA
DE MINIMIS EXEMPTIONS:
Units smaller than 500 hp are exempt from permitting. No state notification is required, but it is strongly
recommended.
MINOR SOURCE PERMITTING:
Sources emitting more than 5 tons per year of a criteria pollutant must obtain a minor source permit. Expected
emissions for NOx, VOC and CO are likely to be listed and various rules will be applied such as:
Units >50 MMBtu/hr heat input have a NOx limit of 0.2 lb/MMBtu for gas, 0.3 lb/MMBtu for liquid fuel and
0.7 lb/MMBtu for solid fuel over a two hour average.
SO2 limits apply to all minor sources and are 0.2 lb/MMBtu for gas, 0.8 lb/MMBtu for liquid fuel and 1.2 lb/MMBtu
for solid fuel. This limit can usually be met with low sulfur fuel.
The state also has a toxic rule that covers 4,000 toxins and individual ambient concentration limits. This rule
has its own BACT, however this is generally not a problem for electric generating units.
Units that cannot meet the above limits will be required to install controls. Sources that emit more than 100
tons per year of any criteria pollutant are required to complete a state-level BACT analysis. The cost threshold
is $8,000-10,000 per ton for NOx.
There is a 30-day public comment period for sources with a potential to emit 100 tons per year or greater. The
total permitting time is anywhere from 3 months to 1.5 years for a large PSD project.
MAJOR NSR/PSD PERMITTING:
A potential to emit 250 tons or more of any criteria pollutant triggers PSD.
EMERGENCY ENGINES:
Emergency engines are treated the same as other units, however the potential to emit calculation is based on
500 hours per year. Emergency units may only operate during emergencies and for maintenance, but there are no actual
run hour limits.
An electrical generation facility does not need the permission of the Oklahoma Corporation Commission. However,
certain environmental and emissions permits must be obtained from the Oklahoma DEQ.

Code changes must go through the state legislature, the governor, and be adopted by the Fire Marshal
Commission. The Commission sets the minimum building requirements for the state.
