Potential to Emit Workbook: Part 2: How to Calculate ...
The fugitive emissions of all regulated air pollutants, other than HAPs from the non-listed source, would not have to be considered in the facility’s PTE calculation. As you identify emission sources, remember to include all sources of air contaminants, such as non-production units like welding or grinding.

Emission Estimation Technique Manual
emissions are very low or zero. There is a wide range of cutting oils, quenching materials, degreasing and cleaning solvents, acids, alkalis and heavy metals used within the structural and fabricated metal product manufacturing industry and as a consequence, it is possible that reporting could

Welding Emissions - California Air Resources Board
May 19, 2011 · Emissions from stainless steel welding are a source of concern because of the potential health impacts from hexavalent chromium. In 2001 the Air Resources Board (ARB) identified hexavalent chromium (Cr+6) emissions from welding as a pollutant of concern and contracted with Dr. Dan Chang (UC Davis) to investigate and improve upon existing ...

Metalworking
The emissions from these dry processes are metal oxides which are similar in particle size to those generated in welding processes. The thickness of the material being cut, the cutting time per piece, and the hours of operation affect pollutant generation and loading.
