Some of these items such as transmission and engine parts contain oil. This oil is the main source of potential emissions from the furnace in the form of combustible particulates and volatile organic compounds(vocs). An afterburner will be installed at each furnace to consume the combustible particulates and VOCs. other items such as lawn chairs, automobile bumpers, semi- trailers and bus skins will emit small amounts of pollutants. These emissions would be from the paints and coatings and would be in the form of particulates. Other items such as shredder breakage, car wheels and computer scrap would emit essentially no pollutants. The U.S. EPA document AP42 "Compilation of Air Pollutant Emission Factors" for secondary aluminum operations under section 7.8.2 Emiszions and Controls states, "Although each step in scrap treatment and smelting/refining is a potential source of emissions, emissions from most of the scrap treatment operations are either not characterized here or represent small amounts of pollutants." Table 1 Calculated Emission Rates for Danny's Aluminum Processing Inc. summarizes the potential emissions from two furnaces operating continuously for 24 hours per day, 365 days per year. The potential emissions, at the 1000 lbs. per hour of recovered aluminum, are considerably less than the 25 tons per year allowed by. the MPCA for an exempt status. The pollutants identified in the secondary aluminum processing industry EPA document 450/4-90-003 (basis for calculating the above Table 1) are particulates, sulfur oxides, nitrogen oxides, volatile organics and carbon monoxide. There is no mention of heavy metals, acid gases or dioxins/furans as being emitted as a pollutant. We therefore again ask that these pollutants not be required to be tested in any monitoring program. The above aluminum feed stock (as discussed above) will generate some particulates and VOCs which will be consumed in an afterburner. The sulfur oxides shown in Table I are identified as a potential source depending on the composition of the organic contaminant in the feed stock. The burner propane fuel will not add any additional sulfur oxides. Therefore, sulfur oxide will not be emitted on a continuous basis from the furnace and will be at low levels when it does. We ask that the sulfur oxide not be tested in any monitoring program since it will not be present on a continuous basis.
