DE MINIMIS EXEMPTIONS:
Sources that have a potential to emit less than 5 tons per year of each criteria pollutant are exempt from
permitting. These sources are not required to notify the state, but it is recommended.
MINOR SOURCE PERMITTING:
Sources with a potential to emit more than 5 tons per year of any criteria pollutant must obtain a minor source
permit. The state will require stack testing if the unit has a potential to emit 40 tons or more of NOx in an attainment
area and any amount of NOx in a nonattainment area. There is a 20% opacity limit and PM emissions must be less
than 0.6 lb/MMBtu. There is also a 2,000 ppm fuel sulfur limit. In nonattainment areas RACT may apply.
There is a 30 day public comment period for sources with a potential to emit greater than 100 tons per year
of a criteria pollutant. The entire permitting process takes about 180 days, but there is no upper time limit.
New NOx emissions factors for 9 parishes geared mostly toward retrofitting old equipment because most new
equipment should meet these standards anyway.
Boilers:
| Coal Fired |
0.21 lbs/MMBtu |
| #6 Fuel |
0.18 lbs/MMBtu |
| Fuel Oil Fired |
0.10 lbs/MMBtu |
Turbines:
| Fuel oil fired, peaking |
0.30 lbs/MMBtu |
| gas fired, peaking |

IGE:
Exemptions: boilers with max capacity less than 80 MMBtu/hr; stationary gas turbines less than 10 MW;
ICE rich-burn less than 300 hp; ICE lean-burn less than 320 hp in Baton Rouge and less than 1500 in regions of influence;
Gas turbines & ICE used for testing, research or performance verification; and Any source used solely to power
a startup point source that fires biomass fuel which acounts for greater than 50% of the heat input monthly.
MAJOR NSR/PSD PERMITTING:
A potential to emit 250 tons per year of a criteria pollutant triggers PSD in attainment areas. 50 tons of NOx
or VOCs triggers NSR in nonattainment areas.
TREATMENT OF EMERGENCY ENGINES:
Emergency units are exempt from permitting, but can only operate during a blackout and for maintenance. No
state notification is required and there is no hourly operating limit.
Division of Fire Safety
The Division sets the minimum fire safety standards in the state.
