Directions: The plant is located on State Highway 141 in Peachtree. From US 74, at Marble,
turn left on 141 and travel approximately seven miles to Peachtree. The plant is on the right on
141.

Description: This facility manufactures avionics and other small motors and gauges.
On July 18, 2018, I met with facility contact Danielle Loyd to inspect the facility. Ms. Loyd
replaced former contact Michael McLean. Ms. Loyd explained that there had been no changes
or modifications to the facility since the last inspection that would increase emissions. -

1. two water curtain-type paint spray booths (ID No. 001 and 016) used in a metal
parts coating operation;
VISIBLE EMISSIONS CONTROL REQUIREMENT - As required by 15A
NCAC 2D .0521 "Control of Visible Emissions," visible emissions from the
nickel plating line (ID No. 007) and the spray booth (ID No. 016), manufactured
after July 1, 1971, shall not be more than 20 percent opacity when averaged over
a six-minute period...
Neither spray booth was not in operation during the inspection. The paint area
was neat and orderly. Closed container available for disposal of used rags.
2. one nickel plating line (ID No. 007);
VISIBLE EMISSIONS CONTROL REQUIREMENT -As required by 15A
NCAC 2D .0521 "Control of Visible Emissions," visible emissions from the
nickel plating line (ID No. 007) and the spray booth(ID No. 016), manufactured
after July 1, 1971, shall not be more than 20 percent opacity when averaged over
a six-minute period
The nickel-plating line was not in operation during the inspection. This line
operates infrequently as job demand requires.
3. one chromium anodizing operation(ID No. 011);

a. MACT Emissions Limitations - During tank operation the surface tension of the
electroplating bath for the affected source shall not exceed:
Pollutant Emission Limit(s)
Affected Source(s)
(dynes/cm)
chromium anodizing operation
40
(ID No 011)
Logbook records indicate surface tension measurements of around 34 with 35
being the highest observed.
b. VISIBLE EMISSIONS CONTROL REQUIREMENT - As required by 15A
NCAC 2D .0521 "Control of Visible Emissions," visible emissions from the spray
booth (ID No. 001) and the chromium anodizing operation(ID No. 011),
manufactured as of July 1, 1971, shall not be more than 40 percent opacity when
averaged over a six-minute period...
This process was not in operation during my inspection. Since the last inspection,
this process has been moved to the basement and the old baths replaced with all new
ones. The vent stack remains the same.
4. One sodium dichromate passivating operation (ID No. 12):
Passivation removes the surface contamination created when stainless steel is
machined and fabricated. These contaminants can result in premature corrosion
that could ultimately damage the component. In addition to surface cleaning,
passivation forms a thin, transparent oxide coating that fights selective oxidation.
This process was not in operation during my inspection.
Fugitive Dust Control Requirement
No fugitive dust emissions were observed beyond the property boundary.
Work Practices Requirements
1. VOC-containing material was properly stored and no spills or waste rags were
observed. No parts washing was observed. All work practices requirements
appeared to be met.
2. The work practice standards for the stalagmometer recommended by the
manufacturer were being followed.
MACT

1. The operation and maintenance plan for the anodizing operation required to comply
with MACT monitoring and work practices was observed. This plan is
maintained electronically on site.
2. The surface tension of the electroplating bath was checked at least every 4 hours
of operation to verify compliance with MACT Emissions Limitations requirement
that the tension shall not exceed 40 dynes/cm. In compliance.
GACT
a. Standard and Manaeement Practices—the facility appeared to be following the
standard and management practices.
CONTROL AND PROHIBITION OF ODOROUS EMISSIONS-As required by 15A
NCAC 2D .1806 "Control and Prohibition of Odorous Emissions" the Permittee shall not
operate the facility without implementing management practices or installing and
operating odor control equipment sufficient to prevent odorous emissions from the
facility from causing or contributing to objectionable odors beyond the facility's
boundary.
No objectionable odors were observed beyond the facility's boundary.
