For the purposes of the above tables,
“E” is the total or specific organic compound emissions in kg/h per part; and
“C” is the measured concentration of total or specific organic compounds expressed in ppmv; if the concentration “C” measured for a part is greater than 10,000 ppmv (C > 10,000 ppmv), use C = 33,620 ppmv in the emission calculation equation for that part.
