Safety Equipment: eye protection,hearing protection
Facility Contacts: Mr.Wilson is the EHS manager and facility contact. He confirmed that all contacts
were up to date.
Facility Description: Snap-On operates a manufacturing facility for pneumatic power tools. Operations
include machining and tool assembly—including metal heat treating, endothermic gas surface treatment,
dip treatment/coating lines,washing, powder coating, and drying. Snap-on operates 3 shifts, 5-6 days per
week.
The facility is split into four zones: office, machining; assembly; shipping. All air emission sources are in
the machining portion of the facility.
This facility(formerly known as Sioux Tools)received a"Permit Applicability Determination"in 2002
that the facility's operations were exempt from air permitting. The 7/31/2002 letter states in part: "should
you decide to modify the process such that the result is an increase in emissions of air pollutants....an air
permit may be required."
The planned installation of a new paint spray booth at Snap-on Power Tools,Inc. led the company to
request registration. Based on emissions of each criteria air pollutant of less than 5 tons/year, negligible
TAP emissions, and aggregate emissions of less than 10 tons/year,this facility qualifies for permit
exemption per 2Q .0102(d). However, in a 5/14/2020 telephone conversation, facility consultant Mike
Fox communicated that the facility wanted to proceed with registration.
Compliance Inspection Narration: I, Mamie Colburn, arrived on site to meet with Mr. Wilson at 10 am
on Tuesday August 24, 2021. Prior to arrival, I called Mr. Wilson to confirm their COVID protocols and
make sure there were no active outbreaks or restrictions. Masks and social distancing were in place and I
followed those protocols upon arrival.
Upon arrival, I met with Mr. Wilson in their conference room to review records and discuss the inspection
process. This is their first DAQ inspection for their optional registration.
Registration Criteria Review:
Mr. Wilson and I discussed the current Facility Wide Emissions estimate of TSP/PM10 completed during
the registration process in 2020. Mr. Wilson stated there have been no changes to the process or
significant increases in production since that review. The following pollutant estimation are for the use of
propane-fired equipment listed in the Air Emission Source Table. Snap-on Tools is currently calculated
as an exempt facility but has chosen to be a registered facility.
Using revised/corrected estimates of TSP/PM10 Emissions, estimated facility-wide potential emissions of
criteria pollutants are:
Pollutant TSP (PM10) NOx CO S02 VOC
Estimated 0.1 2.4 1.4 0 0.2
emissions
(Tons/year)
Note that the potential emissions in the table above are from maximum propane combustion from all
combustion sources(8760 hours/year at maximum burner ratings).
As stated above,this facility could be exempt from permitting per 2Q .0102(d)which exempts:

d)Any facility whose actual emissions ofparticulate matter(PM10), sulfur dioxide, nitrogen oxides, volatile
organic compounds, carbon monoxide, hazardous air pollutants, and toxic air pollutants are each less than five tons
per year and whose actual total aggregate emissions are less than 10 tons per year shall not be required to obtain a
permit pursuant to 15A NCAC 02Q.0300. This Paragraph shall not apply to synthetic minor facilities that are
regulated pursuant to 15A NCAC 02Q.0315.
Emission Source Inspection:
The following air emissions sources were viewed during an inspection of the facility. The majority of
these sources are in the machining portion of the facility:
Air Emission Source Heat input Seen?In Operation?
Heat treat Furnace No. 1 0.58 mmBtu/hour In operation. No VE.
(propane fired) maximum heat input rate
Heat treat Furnace No.2 0.58 mmBtu/hour In operation.No VE.
(propane fired) maximum heat input rate
Temper Room No. 1 0.80 mmBtu/hour AKA—draw furnace. In operation. No
(propane-fired) maximum heat input rate VE.
Temper Room No.2 0.80 mmBtu/hour AKA—draw furnace. In operation.NO
(propane-fired) maximum heat input rate VE.
Wash/heat treat room 0.80 mmBtu/hour In operation.
(propane-fired) maximum heat input rate
Endothermic Generator 0.12 mmBtu/hour In operation.
(propane-fired) maximum heat input rate
Dip line consisting of four 0.12 mmBtu/hour Seen.Recently used.
dip tanks and associated maximum heat input rate
propane-fired burner
Two dry filter type paint N/A In operation w/disposable filters.
spray booths Pressure drop of A in each. No VE.
Two heat treat furnaces, which are propane fired,were seen in operation in the machining room. Propane
flares are visible on each of these furnaces. These furnaces are used to harden and cure machined metal
parts for pneumatic drills. Temper room 1 & 2 are near the furnaces and were in operation. The wash/heat
treat room was also seen in operation. Temperatures around the equipment is very high with open flames
in some cases. I viewed this equipment from a 20-foot distance.
The dip-line and propane fired burner had been used earlier in the day. Finished metal product was
viewed at the end of this line. Filter-type spray booth was viewed in operation under negative pressure.
Pressure drop was visible as -1 inch and Mr. Wilson stated the booths had disposable filters. Dates of
filter change out were not readily available.

In addition to the above-listed sources,the following operations are listed in the request for registration as
operations which emit negligible air pollution(emissions not quantified).
Operation Comment Seen? In operation?
Powder paint cure Electrically heated In operation.
oven/Heat Treat Room curing oven
Gage Coating/Gage AKA—Wax dip Seen.Not in operation. Recently used
Crib
ALMCO Wash System In operation.
Drying Oven/Plant Electrically heated Seen in operation at 1200 F
drying oven
The powder paint cure oven was on but functioning at a lower temperature than normal operations due to
needing repair. The gage coating/gage crib is a small wax dip tank the size of a large sink. Wax is dipped
onto metal ends to protect them in shipping. Dipped metal was observed.The Drying oven/Plant was seen
in operation,running at 12000 F.
Prior to going into the building I saw what appeared to be steam from a stack emitting from the south
Side of the building. I spoke to Mr. Wilson about this and he said it was process steam. After the interior
inspection, I walked to the outside of the building to view any potential emissions including this side
stack. It did appear to be condensing steam.This steam is highly visible when viewing the building from
afar.
