Abstract
The report gives results of an EPA/IERL-RTP Level 1 environmental assessment of fumes generated at one steel plant. Purpose of the assessment was to develop preliminary information on the organic and inorganic matter generated in three processes: (1) external hot metal desulfurization (HMDS), (2) hot metal charging to the basic oxygen furnace (BOF), and (3) oxygen blowing of the BOF. Fumes generated (before emission control) during HMDS contained about 0.64 kg of particulate and 0.001 kg of organic per Mg of metal desulfurized. Sufficiently high concentrations of some metals were found to require that highly efficient dust capture and environmentally sound disposal be practiced. Fumes generated (before control) during BOF hot metal charging contained about 0.053 kg of particulate and 0.00058 kg of organic per Mg of hot metal charged. Sufficiently high concentrations of some metals were found to require that good dust capture and disposal be practiced. Dust from the BOF baghouse also contained about 100 mg PNA/kg of dust; the PNA source was not determined. About 11 kg of particulate and 0.004 kg of organic per Mg of steel processed in the BOF is captured by the primary emissions of control scrubber during the oxygen blow period. Concentrations of some metals in the clarified recycle water would be of concern if discharged to surface waters.
