Emission control
Emission control
(OP)
To be able to use dispersion modelling I am looking for maximum allowable emissions. I checked the EPA, EU and WHO maximum allowable concentrations for NOx, SO2, CO but they all give total 8 hour concentrations and yearly means. Is there a rule for the maximum contribution one plant is allowed to have?
Cheers,

RE: Emission control
SO2 -> 350 µg/m³ as an average value over 1 hour continuous measurement (alarm value 500 µg/m³)
NOx -> 200 µg/m³ as a 98%-value of cumulative probability curve from average values (alarm value 400 µg/m³)
CO -> 10 µg/m³ as 8-hour-average.
these values are true for a single plant.
for further information, i'd suggest looking for an english language version of the german "Bundesimmissionsschutzverordnung" or, short, "BImSchV". it has those values, as well as the maximum values for short-time-peaks ("alarm-values")

RE: Emission control
If in the US, check with your Regional EPA office. They will have the answers you're looking for. They are only a phone call away.
Hope this helps.
