This facility produces a variety of custom engineered automotive components. Final products include gas charged lift supports and vacuum 

motors. Unit operations include metal stamping, assembly, copper brazing, zinc electroplating, painting, metal cleaning, abrasive blasting and 

wastewater treatment.

FACILITY DESCRIPTION

This facility is being assigned a facility-wide limitation of single HAP less than 10 tpy and total HAP less than 25 tpy. This federally 

enforceable limitation is being assigned as a MACT avoidance limit for 40CFR63 Subpart MMMM (National Emission Standards for 

Hazardous Air Pollutants for Surface Coating of Miscellaneous Metal Parts and Products). No changes to any equipment or process are 

occurring as a result of this action.

PROJECT DESCRIPTION

REGULATIONS

40CFR63 - National Emission Standards for Hazardous Air Pollutants for Source Categories (MACT)

This facility meets the applicability requirements of 40CFR63 Subpart MMMM (National Emission Standards for Hazardous Air 

Pollutants for Surface Coating of Miscellaneous Metal Parts and Products). However, this facility has requested limits on individual and 

total HAP emissions to remove it from being designated as a major source of HAP’s. 

Tables 1 and 2 list the estimated potential uncontrolled and controlled non-criteria pollutant emissions from this facility. Tables 3 and 4 list 

the criteria pollutant emissions from this facility. The Zinc Plating Scrubber will be used to limit HAP emissions to below major threshold 

levels of 10 tpy of individual HAP emissions and total HAP emissions of 25 tpy.
