Secondary Aluminum Melting Furnace
Pollutant Achieved in Practice or in the SIP Technologically Feasible Alternate Basic Equipment
NoxSweat Furnaces: 50 ppmvd @ 3% O2 (Use of Low-Nox Burners) Holding Furnaces: 40 ppmvd @ 3% O2 (Use of Low-Nox Burners) Reverb Furnaces: 53 ppmvd @ 3% O2 (Use of Low-Nox Burners)Sweat, Holding, and Reverb Furnaces: 1. 6.0 ppmvd @ 3% O2 (Use of Low-Nox Burners and Selective Catalytic Reduction) 2. 12.0 ppmvd @ 3% O2 (Use of Low-Nox Burners and Regenerative Selective Catalytic Reduction) 3. 30 ppmvd @ 3% O2 (use of Low-Nox Burners and Selective Non-Catalytic Reduction)1. Use of Electric Furnaces
PM10Sweat Furnaces: use of natural gas fuel, afterburner with 1400 F chamber temperature, and a baghouse with fabric filters Holding and Reverb Furnaces (non-sweating): use of natural gas fuel and a baghouse with fabric filters


BACT is the most stringent control technique for the emissions unit and class of source. Control techniques that are not achieved in practice or contained in s a state implementation plan must be cost effective as well as feasible. Economic analysis to demonstrate cost effectiveness is requried for all determinations that are not achieved in practice or contained in an EPA approved State Implementation Plan.

This is a Summary Page for this Class of Source. For background information, see Permit Specific BACT Determinations on Details Page.
