Footnotes to the table:
a Where a substance falls into more than one category, the lower ELV applies.
b The mass flow is calculated in kg/h for the raw gas and is determined at the point before any
gas cleaning or abatement plant, but after any devices inherent in the process (e.g. after reactor
overhead condensers or after product cyclones). Mass flow is the maximum emission which can
occur over any one hour period of plant operation, from the entire site. Where the mass flow
exceeds the mass threshold, then abatement will be required down to the appropriate ELV,
unless the concentration of the raw gas is already below the ELV, in which case no further
abatement is required.
c Where organic substances of several classes are present, in addition to the above limit, the
sum of classes I and II shall not exceed the class II limit and the sum of classes I, II and III shall
not exceed the class III limit.
