The Standard Industrial Classification (SIC) system has been replaced by the North American Industry Classification System (NAICS).  Since the Bureau of the Census has collected the information necessary to classify establishments on both an NAICS and an SIC basis, the same 1998 data can be shown on both the old and the new basis in bridge tables that allow comparisons between the two systems.  These data are hereby produced for the last time on an SIC basis for 1998 at the national level only. 

(a) Purchased steam excludes quantities delivered from any other establishment(s) in the company, quantities transferred from other establishments of the company for which payment was not made, quantities purchased centrally within the company but separate from the reporting establishment, and quantities for which payment was made in-kind.

(b) Biomass Total  is the sum of the estimates for these four components: agricultural waste, wood harvested directly from trees, wood residues and byproducts from mill processing, and wood-related and paper-related refuse.

(c) Biomass Total does not include pulping liquor or black liquor.
