Clarification and Guidance for the Metal Fabrication Industry

During the processing of the aluminum slabs into posts, 11,000 pounds of fumes and dust are generated from the cutting, grinding, and polishing of the aluminum which is either released as fugitive emissions or is disposed in an off-site landfill.

Pollution Prevention in Machining and Metal Fabrication

Air Emissions The use of metal working fluids in metal shaping and metal removal processes may result in fugitive emissions in the form of smoke, mist, or vapor. Other processes may create more hazardous air emissions. Possible sources of air emissions in metal fabrication processes are: • smoke emissions from metal removal processes

Machining Grinding Sanding - sdapcd.org

The District has not prepared default emission calculation procedures for machining, grinding and sanding equipment. Emissions are typically calculated based on a material balance on the amount of material being processed. To obtain assistance identifying a procedure or emission factors for calculating emissions, contact the District.
