Sec.  503.44  Operational standard--total hydrocarbons.



    (a) The total hydrocarbons concentration in the exit gas from a 

sewage sludge incinerator shall be corrected for zero percent moisture 

by multiplying the measured total hydrocarbons concentration by the 

correction factor calculated using equation (7).

Where:



X=decimal fraction of the percent moisture in the sewage sludge 

incinerator exit gas in hundredths.



    (b) The total hydrocarbons concentration in the exit gas from a 

sewage sludge incinerator shall be corrected to seven percent oxygen by 

multiplying the measured total hydrocarbons concentration by the 

correction factor calculated using equation (8).

Where:



Y=Percent oxygen concentration in the sewage sludge incinerator stack 

exit gas (dry volume/dry volume).



    (c) The monthly average concentration for total hydrocarbons in the 

exit gas from a sewage sludge incinerator stack, corrected for zero 

percent moisture using the correction factor from equation (7) and to 

seven percent oxygen using the correction factor from equation (8), 

shall not exceed 100 parts per million on a volumetric basis when 

measured using the instrument required by Sec.  503.45(a).
