'1" '" Use emission factors developed for each type of welding operation and type of welding rod. Consult the EP A document "AP-42, Compilation of Air Pollutant Emission Factors, 5th Edition," Chapter 12.19, Electric Arc Welding. AP-42 is available at the Lane Re- gional Air Pollution Authority, the University of Oregon Library, the Eugene Fire Mar- shal's Office, and on the internet at http://www.epa.gov/ttn!chief/ap42etc.html. Identify the welding process used (shielded metal arc welding is the most common), and the electrode type from the MSDS, then refer to Table 12.19-1 to find total fume emission factor. The table breaks these down further into Hazardous Air Pollutants (HAPs). , if 9. QUESTION: What is the proper output type under which to report welding material that becomes a part of manufacturing equipment? 'f ANSWER: Only the fumes are reportable, as output type 5, quantity emitted to the air. Metals used in welding are not reportable as they are not chemically altered in process- Ing. 10. QUESTION: We cut copper wire into segments which are then wound around a motor part. The ends are not stacked and our engineer has determined that no copper is re- leased. Is the wire still an article? ANSWER: Cutting the wire into segments and winding it around a motor part do not negate the exemption since the diameter and thickness of the wire is not changed. The copper wire remains an article as long as no toxic chemicals are released during use. Since your engiI1eer has determined that no copper is released, the article exemption does apply and the copper wire does not have to be reported. 11. QUESTION: Copper wire at a facility is cleansed by dipping it into a sulfuric acid solution. The acidic solution etches away a portion of the surface of the wire. The etched copper reacts with the acid to form copper sulfate. The waste stream containing the copper sulfate is sent directly to a publicly oWned treatment works (pOTW) and no other releases of copper occur on-site to any other environmental media. . Is the copper wire still considered an article? ANSWER: The copper wire is not reportable, but the copper sulfate is reportable as copper compounds (category N100). In this case, estimate this output and use that num- ber of pounds as the input also. 12. QUESTION: A facility crushes light bulbs and uses the crushed glass in their process. The light bulb stems are not used in the process and are disposed. There is a lead "but- ton" in each light bulb stem that is disposed. Is this button considered an article and therefore exempt from threshold and other materials accounting calculations? ANSWER: It depends. If the lead buttons were recovered and re-used in manufacturing of new light bulbs, and the lead buttons fulfill all "article" criteria, they would not be reportable. But if they are disposed, then they would not be considered articles and the F-4
