Emission control

[JCVO]

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,

Hans

German legislation demands following maximum values:

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&quot

JCVO, Here in the US, emissions limits are dependant on gegraphic location and prevailing air pollution problems. If the plant is located in what is considered a severe non-attainment area the allowable limits will be exceeding low. Whereas, if the plant is located in an area that is not problematic, the limits will be set higher. Unless of course this is a new source, in which case the Regional EPA will mandate max. allowable limits and operating times. Either way, you will be pulled into the Emissions Reduction Management System which is a part of the Title V Air Permit which all plants are required to have and which is quite extensive and complicated.

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.
