Description: This facility manufactures avionics and other small motors and gauges.
On April 11, 2022, I met with facility contact Danielle Loyd and Mr. Mike Murray to
inspect the facility. Mr. Murray is the assistant to Environmental contact Danielle Loyd. Ms.
Loyd stated that there had been no changes or modifications to the facility since the last
inspection. Ms. Loyd explained that while the demand for bi-pap and the other breathing assist
products was down since last year with the waning of Covid,they have had increased orders for
other products like parts they manufacture for the Javelin anti-tank missile.

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...
Observed but not in operation during inspection. 0% visible emissions.
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.
This line operates infrequently as job demand requires.
Observed but not in operation during inspection. 0% visible emissions.

3. one chromium anodizing operation (ID No. 011);
a. MALT 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. 45
(ID No. 011)
Logbook records indicate surface tension measurements were well below the 45
dynes/cm limit with most readings 34 or 35 dynes/cm.
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...
Observed but not in operation during inspection. 0% visible emissions.
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.
Observed but not in operation during 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. Although no longer a requirement,
permitted work practice standards appeared to be met.
2. The work practice standards for the stalagmometer recommended by the
manufacturer were being followed.

MACT, Subpart N - Decorative Chromium Electroplating and Chromium Anodizing Tanks
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. Records were observed to be in
compliance.
GACT, Subpart XXXXXX - Standards for Metal Fabrication and Finishing Operations
a. Standard and Management Practices—the facility appeared to be following the
standard and management practices.
b. Recordkeeping Requirements- Observation of this record was accidentally
omitted by the inspector, however previous inspections have been in compliance.
c. Reporting- Report received on 1/24/22 indicating compliance
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.

This facility operates a mostly automated line that produces bi-pap and other breathing assist
devices. None of these lines appear on the permit, however I learned that there was a gluing
component to the manufacturing process. I requested that Ms. Loyd submit information about
the gluing process including usage, and capture efficiency for the control devices which are all
vented inside. Submitted data indicate that emissions are very small however the permit
engineer may want to add the process to the insignificant list.
5 Year Compliance History
A review of the 5 year compliance history revealed no compliance issues.
Compliance Statement:
Moog, Inc. appeared to be in compliance by inspection with permit No. 07680R06. The permit
engineer may want to add the aforementioned gluing process to the insignificant list.
