Question # 612

612. Are SOCMI (Synthetic Organic Chemicals Manufacturing Industry) emissions factors applicable to the petroleum refining industry as well as to organic chemical manufacturers?
Yes, SOCMI fugitive emissions factors can be used for the petroleum refining industry even though they are based upon synthetic organic chemicals manufacturing. The refinery user would have to correct for differences in concentrations of the mixtures, because SOCMI factors are based upon pure substances being released.
