OPERATING STATUS: Operating normally at the time of inspection.

PROCESS DESCRIPTION: Manufacturing process for typical gear and housing: The process
begins with bar stock cut to length and rough turned on a lathe. It
is then sent to heat treat for a normalize cycle which refines the
grain of the steel and makes it more machinable. The gear is sent
to finish turn where it is machined to its final overall shape, then
to deburr to remove all burrs from the part. The gear is sent to
the plate shop, masked, and copper plated. Copper plating serves
as a maskant in the carburizing process to prevent carbon from
being absorbed in the areas of the gear that are not designed to
become as hard as others.

The gears are then sent to heat treat for carburization. The parts
are heated to approximately 1,700 degrees Fahrenheit in a
vacuum atmosphere; propane or acetylene is then introduced into
the atmosphere as a source of carbon. The unplated surfaces
absorb the carbon like a sponge. The gears are quenched in either
oil or nitrogen. Next, the gears go into a hardening furnace at
approximately 1,500 Fahrenheit for a prescribed time, and
quenched in oil quench press or open bath quench. Hardening
makes the entire gear harder, but the areas that have more carbon
become even harder than the rest of the part. The parts are then
sent back to plating for copper strip. The gears then go to the
) $ ' $ '
2
metallurgical lab along with a sample to determine proper heat
treatment.

Manufacturing process for specialized housings: The castings are
sent to plating where they are treated with Type II Anodized in
sulfuric acid to give them an oxide and abrasion resistant anodic
coating. The housings are then sent out to be machined on
various types of milling machines to bring them to their final
dimensions. They then go to the NDT department
(Non-Destructive Test) where they are dipped in a fluorescent
mineral oil solution, washed, developed, then inspected under a
black light to look for any cracks in the surface. Next, they go to
deburr where all burrs and any roughness is removed, and to
final inspection where they are measured against their required
tolerances. After inspection, they are sent back to plating for a
chemical conversion coating to protect any of the surfaces that
were machined since the anodize process. The housings then go
to the assembly department where needed hardware is installed
(studs, inserts etc.), and pressure tested to ensure there are no
leaks/holes in the internal cores of the housing. Once this is done
the housing goes to final inspection where they are completely
inspected per print and then taken to stores. Finally, the gears,
housings, and various purchased parts are drawn from stores and
the final gearbox assembly takes place. The assembled
gearboxes are painted, inspected, tested, packaged, and shipped.

Section III: APPLICABLE FEDERAL REQUIREMENTS

In addition to the requirements of this AO, all applicable provisions of the following federal programs
have been found to apply to this installation. This AO in no way releases the owner or operator from any
liability for compliance with all other applicable federal, state, and local regulations including UAC
R307.

MACT (Part 63) T: National Emission Standards for Halogenated Solvent Cleaning

Status: In Compliance. This facility maintains an enclosed vapor degreaser with a refrigerated
condenser deck using trichloroethylene as solvent. The refrigeration coils create a cold air blanket
which converts the vapors into liquid which keeps the vapors from rising. The degreaser is
equipped with a cover that only opens when someone steps on the operation deck. The cover was
free of cracks, holes, or other defects. Monthly checks are performed to measure hoist speed.
Records indicate that the speed remains under the 11 feet per minute requirement. Weekly
inspections are conducted to monitor the liquid temperature (173 degrees Fahrenheit minimum),
chiller temperature (52.2 degrees Fahrenheit maximum), and air blanket temperature (52.2 degrees
maximum). Preventative maintenance logs for the vapor degreaser were reviewed. The degreaser
service manual is kept in the maintenance shop. Operators are routinely trained to follow the
required procedures. An annual Halogenated Solvent Cleaner Report dated January 15, 2025, was
submitted to the DAQ and was reviewed on February 20, 2025. See the attached Halogenated
Solvent Cleaner NESHAP Annual Report. See also attached vapor degreaser PM.

MACT (Part 63) ZZZZ: National Emissions Standards for Hazardous Air Pollutants for Stationary
Reciprocating Internal Combustion Engines

Status: In Compliance. The 60-kW generator was manufactured in 1979. The 30-kW generator was
manufactured in 1992. Each generator is used annually for less than 100 hours for maintenance
and other non-emergency purposes. Maintenance occurs per manufacturer recommendations, and
the non-resettable hour meter is checked weekly. Only natural gas is used in the generators.

9
MACT (Part 63) WWWWWW: National Emission Standards for Hazardous Air Pollutants: Area Source
Standards for Plating and Polishing Operations

Status: In Compliance. This facility operates a plating and polishing operation which includes nital
etching, copper plating, anodizing, and material stripping. An automated hoist system is used to
withdraw parts slowly from the tanks to maximize the drip time of the solution back into the tank.
Racks are specifically designed for each part and to allow solution to drain off as optimally as
possible. Plating tanks are washed daily and weekly to avoid contamination and ensure quality
control. Spills and overflows are avoided by the use of a "deadman valve" which requires the
operator to hold down a button with their foot as the tank fills. This prevents the operator from
walking away while the tank fills. Regular preventative maintenance is followed. Any failing
equipment is immediately repaired or replaced. Records are kept for a minimum of five years. See
the attached Annual Subpart 6W certification for 2024, dated January 23, 2025.

Install air hose on W-7. Turn on air hose and catch debris in bucket. Repeat 3 or 4 times. Reinstall
thermocouple and turn valves W-3 and W-4.
5. Check lid for proper operation.
6. Check Yamada (pneumatic) pump for proper operation.
7. Clean screen on suction side of Yamada (pneumatic) pump.
8. Check for rust residue in tank. Rust residue implies Trich turned to acid. Report if needed.
9. Check that frost drain tray is clean and flowing.
10. Check that separators are clean. Open drain valve. Inspect that solvent is clear not dirty.
11. Check Water Temperature Safety Control: Unplug the WTC Thermocouple located at the
bottom of the pipe next to the front of the stairs. Check that heaters shut off. Also, pipe should be
cool to the touch. Make repairs as needed if heaters do not shut off.
12. Check Safety Flow Switches: Turn off W3 water valve this will turn off the water to tank cooling
system and the heat exchanger for the wand which will turn off the front flow meter. Turn off W2
water valve this will turn off the cooling water to the refrigeration compressor which will turn off the
back flow meter. In both cases the red light on the back of the flow meter will go out. Check that
heaters shut off. Make repairs as needed if heaters do not shut off.
13. High Temperature Safety Control: Disconnect HTC thermocouple located at the bottom of the
solvent tank on the east side. Check that heaters shut off. Make repairs as needed if heaters do
not shut off. After reconnecting the thermocouple, the SVC reset button must be pressed to reset
the fault.
14. Check Vapor Safety Control: Disconnect SVC thermocouple located on the southwest corner of
the solvent tank behind the refrigeration compressor. Check that heaters shut off. Make repairs as
needed if heaters do not shut off. After reconnecting the thermocouple, the SVC reset button must
be pressed to reset the fault.

the degreaser tank. Low level control should be checked during solvent change out and cleanout.
When solvent tank is empty. The top lid can be removed by removing the screw at the very top and
lifting the lid off the level switch. The mercery switch should be tilted in the low-level direction. Also,
at this time the pipes for the low-level switch should be cleaned by removing the two pipes. Plugs
and pushing a bottle brush through the pipes. After cleaning replace the pipe plugs and close the
gate valve to the right.
16. TH1 Vapor Up Spray Safety Switch: The spray wand will not work unless the THI control is
active, or up to temperature. To test turn on wand, then turn TH1 controller dial up about 10 deg.
Wand contactor should shut off. To reset turn, dial back to correct position approximately 110 deg.
