PHYSICAL LOCATION: Highway 76 East, Marion, SC

SIC/NAICS CODE(s): 3499/332999

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

motors. Unit operations include metal stamping, assembly, copper brazing, zinc electroplating, painting, metal cleaning, abr asive 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 Standar ds for

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

occurring as a result of this action. 

### PROJECT DESCRIPTION

REGULATIONS

40CFR63

- National Emission Standards for Hazardous Air Polluta nts 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 ha s 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 f rom 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 t py.
