b "Major Byproduct" fuels include coke oven and blast furnace gas (produced primarily in the blast furnace industry, SIC 3312); still gas (produced primarily in

refineries, SIC 2911); and pulping liquor (produced primarily in pulp and paper mills, SIC 2611 and 2621). c "Fuel Oil" includes distillate and residual.

* Estimate less than 0.5. Data are included in higher level totals.

W=Withheld to avoid disclosing data for individual establishments. Data are included in higher level totals.

Notes: To obtain a RSE percentage for any table cell, multiply the cell’s corresponding RSE column and RSE row factors. Totals may not equal sum of

components because of independent rounding. Operating ratios were calculated using the input energy estimates reported in Table A4.
