GACT/MACT Applicability:Subject to MACT Subpart 6H-Paint Stripping & Miscellaneous Surface
Coating Operations—facility uses surface coatings with chromium and lead(no manganese,nickel,or
cadmium); facility does not use any paint stripping containing McCI. Not subject to MACT Subpart 4Z—
Reciprocating Internal Combustion Engines—facility has no emergency generators.
1) Location
Coffing Hoists is located at 2020 Country Club Road,just outside of Wadesboro,NC in Anson County.
Directions
From FRO,take Hwy 401 South to Wagram.Turn right at Old Wire Road(Hwy 144) and go-- 11 '/2 miles
to Laurel Hill.Turn right at Hwy 74 and go west— 35 miles to Wadesboro.Turn left onto Hwy 52 South
and go — 1 1/2 miles to Country Club Road.Turn left and entrance to building is about 50 yards on right
hand side.Enter through front office.
Safety considerations: Standard DAQ safety equipment.Be aware of forklift traffic in the warehouse,as well as
the heavy hoists that are transferred via overhead conveyor systems to the paint booths.
2) Facility and Process Description
Coffing Hoists Company manufactures electrical and hand operated chain hoist equipment, and is a
Division of Columbus McKinnon Corporation.This facility operates under Air Permit No.3671R09,
effective from 16 October 2009 until 30 September 2013. Cindy Grimes conducted the last compliance
inspection on 21 June 2011.
Most of the hoist components parts are pre-caste or pre-molded metal parts (i.e. different size metal hoist
housing), with the motors and other parts received as raw finished products.There are eight(8)assembly

work cells in the facility, which assemble the different types of hoists and chain pulleys that Coffing Hoists
makes. The assembled hoists and chain pulleys are manually spray painted and labeled within different paint
spray booths.The metal grinding and sanding operations are done to smooth out the inner and outer surfaces
of the metallic hoist housing. A fabric filter is located inside the facility and is installed on these two
operations,and this fabric-filtered air is exhausted to the inside of the building; the particulate is collected
inside a 55-gal drum.
Grinding metal parts generates metal particles that are collected by suction hoses immediately behind the
grinding wheel and then collected in a barrel; thus, it is a self-contained dust system(Note: A wet scrubber
used to be permitted here for the metal working operation; the scrubber is no longer needed due to the size of
material collected).The total facility is an 180,000 sq. ft. process and storage operation,the process area
being-60% and the storage area-40%.
Note: Coffing Hoists has undergone various physical changes since 2009,due to one of their plants in
Michigan shutting down. Some of that plant's newer equipment was brought to Wadesboro and was either
incorporated into its production or put into storage for the time being.Three"new"paint booths from
Michigan were added to the permit(ES-SPR-7, 9, and 14),but only two were actually installed(ES-SPR-9
and 14). One original booth remained(ES-1375) and ES-0704 spray paint booth was disassembled and
removed. Thus,there currently are three operational spray paint booths here.

3) Inspection Conference
On 16 April 2013, I Mike Thomas of FRO DAQ met with Rena' Hart,Environmental Health and Safety
Manager, and Debbie Taylor, Office Manager.This was a prearranged inspection to discuss permit renewal
and to assist with their Emissions Inventory.
a) Verified the FACFINDER information;Ms. Clappse is no longer with the facility in Wadesboro. Ms.
Hart has taken over her responsibilities.
b) Ms.Hart informed me of several pieces of equipment that are no longer physically at the facility. These items
will be pink sheeted to be removed during the upcoming permit renewal.
c) I observed the records and spreadsheets used to track the daily and monthly use of paint and VOCs. They do an
excellent job with record keeping.
4) Inspection Summary
Ms. Clappse and Ms.Taylor led me on a tour of the facility, which was operating. I observed the following:
a) Spray Paint Booths
i) ES-1375-Electric hoists are painted here,with filters changed- 2-3 times/week; it was operating and
I observed no problems.
ii) ES-0704-This booth is no longer operating and has been removed from site.

iii) ES-SPR-7-This booth is no longer operating and has been removed from site.
_ iv) ES-SPR-9-The"entruck"hoists are painted here; it was not in operation at the time,but had
operated earlier in the day. I observed no problems.
v) ES-SPR-14-The large"Shaw Box"brand hoists are painted here.This booth is totally enclosed and
has two types of filters, an intake filter in the ceiling and another large filter throughout the floor area.
These filters are"long-term" and are changed-every 3-4 months.All painting is done with both end
doors shut and once the hoist is completed, it is conveyed overhead via a transfer system to an infrared
drying area adjacent to the booth.The hoists are then dried for- 30 minutes.This booth was operating
and I observed no problems.
All three active booths are clearly labeled, according to the permit Emission Source 1D.There are currently
- 100 total hoists painted per day within all of the booths.Filters are changed between 2-3 times/week
depending on the amount of paint used,and they are changed at the end of I"shift.I noticed that the areas
immediately outside of the booths were clean, and all of the handling, cleaning and storage areas near the
booths were clean as well. Operators keep a filter log outside of each booth,noting when the filters are
changed. I checked each log, and all had current entries.
b) Spill Containment Areas:There are two spill containment areas.The first area is where the bulk
transmission fluid is housed, and it contains a 3000-gallon holding tank where all used oils are stored.
When the tank is full,the oils are pumped out and disposed of as hazardous waste.The second area is
where a 1000-gallon holding tank is housed.This is where cleaning solutions,which are used to wash
the hoists before they are painted, are dumped and held before they are taken away as waste. Each 350-
gallon cleaning tank(there are four) contains approximately 200 gallons of cleaning solution(14
gallons of solvent are generally used per 350 gallons of water).Each cleaning tank has a MSDS sign
specifying what solvent is used in that tank.These tanks are dumped- every 2 weeks into the holding
tank and replaced with fresh solutions.
c) Foam Packaging Area (IES-FP):There are two sections where this packaging foam is dispensed, one
within the shipping area and the 2"d area near paint booth ES-1375.The system consists of a foam
packaging machine, which uses conventional packaging foam from 55 gallon drums. I saw no problems
here.
d) Metal Grinding Operation (IES-937):This area only operates - once a week and is used to grind
any pieces of metal off various facing parts. Once done, the operator sweeps up the metal fragments
and disposes of them. It was not operating during my inspection, and the area was fairly clean.
