Process Description
Steel components are stamped and cut to size for utility truck cabinets. Steel panels are shaped if necessary and
staged for fabricated. Once the units are welded together,they may be conveyed to one or more of the following;
the dip-coating process line,the top-coat spray booth,the undercoating spray booth,the caulk booth and/or the
touchup and rework spray booth. Some of the truck body are attached to stock truck bodies at the Burnsville
facility,but most are staged for loading on flatbed truck trailers and are sent to the Altec facility in Creedmoor,
North Carolina to be joined to truck bodies.

Inspection Observations
On April 10,2020,1 conducted a partial compliance evaluation of Altec Industries,Inc.in Burnsville,North
Carolina. I spoke with Bruce Stainbrook(corporate environmental manager)via a phone call.
Mr. Stainbrook stated that the plant was running at full capacity. The facility has an exempt emergency generator
that is subj ect to NSPS ZZZZ. The facility is keeping track of meter hours. Last maintenance on the engine was
performed on February 20,2020.
The facility has added a significant amount of process area to the back of the production floor and expects to do an
additional expansion in the near future. While this allows for increased production,it should not affect their ability
to comply with synthetic minor emission limits. During 2017 Altec also began using zirconium in the dip coating
operation instead of the phosphate. This is not expected to impact air emission rates.
Rule Review
2D.0515 -Particulate Emissions from Miscellaneous Industrial Processes-Emissions of particulate from any stack,
vent,or outlet of any industrial process for which no other emission control standards are applicable shall not exceed
the amounts calculated by the following equation:
E=4.10xPo.w
where,
E=allowable emission limit in pounds per hour
P=process weight rate in tons per hour
According to the initial permit application,the maximum process weight rate through the paint spray booth will vary
depending on what parts are being coated. However,to be conservative,a process weight rate of 500 pounds per
hour is assumed. Using the above equation,this relatively low process rate leads to an allowable emission rate of
1.62 Ibs/hr. Based on information contained in the initial permit application,the calculated maximum hourly PM
emission rate from the spray booths is 1.071bs/hr. Compliance with 2D.0516 is expected.
2D .0516 Sulfur Dioxide Emissions from Combustion Sources-This regulation limits SO2 emissions from
combustion sources to 2.3 pounds per million Btu. Sulfur dioxide emissions from natural gas combustion are 0.6 lb
sulfur dioxide per million standard cubic foot(ref.AP-42 Table 1.4-2). The sulfur dioxide emission rate calculates
as:
(0.6 lb SO2/ 1,000,000 scf) * (1 scf/1020 Btu)* 1,000,000 Btu/1 mmBm=0.0005881b/mmBtu
Compliance with 2D .0516 is indicated while combusting natural gas. We verified that all combustions sources
were firing natural gas at the time of this inspection.
2D.0521 -Control of Visible Emissions-In order to comply with 2D .0521,the visible emissions from the facility
shall not be more than 40 percent opacity when averaged over a six-minute period except that six-minute periods
averaging not more than 90 percent opacity may occur not more than once in any hour nor more than four times in
any 24-hour period for sources manufactured as of July 1, 1971. For sources at the facility manufactured after July
1, 1971,visible emissions shall not be more than 20 percent opacity when averaged over a six-minute period except
that six-minute periods averaging not more than 87 percent opacity may occur not more than once in any hour nor
more than four times in any 24-hour period. Mr. Stainbrook indicated that the facility did not have issues with
visible emissions. Compliance with 2D .0521 is expected.
2D.0535-Excess Emissions Reporting and Malfunctions-This regulation requires timely reporting and
appropriate actions during periods of excess emissions and malfunctions. No such reporting has been received and
Mr. Stainbrook stated that no excess emissions occurred at the facility.
2D .0540-Particulates from Fugitive Dust Emission Sources-This regulation was amended effective August 1,
2007. The regulation formerly addressed only certain types of processes. The amended regulation addresses all
facilities with activities such as:unloading and loading areas,process areas,stockpiles,stockpile working,plant
parking lots,and plant roads(including access roads and haul roads). The regulation requires a fugitive process dust
plan and abatement measures if substantive complaints are verified. Fugitive emissions could not be verified during
the partial compliance inspection. Compliance is expected.

2D .1806-Control and Prohibition of Odorous Emissions-This regulation requires the owner or operator of a
facility to not operate without implementing 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. There have been no odor complaints with regards to this facility. Continued compliance with
Rule 2D .1806 is expected
2O .0315 -Synthetic Minor Facilities-This regulation allows facilities with potential emissions above major source
thresholds to take voluntary,federally enforceable emission limitations to reduce their potential-to-emit and
preclude Title V applicability. Although this facility would typically be classified as prohibitory small,Altec
specifically requested synthetic minor classification instead. The facility tracks actual usage of each material
containing VOC and HAP,and calculates monthly VOC and HAP emissions by mass balance. The latest annual
report received from the Permittee covers 2019 and met the synthetic minor emission limits. According to Mr.
Stainbrook,the facility is keeping track of VOC emissions on a daily basis. Compliance with the synthetic minor
emission limits and reporting requirements is indicated.
2Q .0711 -Emission Rates Requiring a Permit-The annual report of emissions for 2018 states that TAP emission
rates are well under their respective Toxic Pollutant Emission Rates(TPERs)as shown below. TAP emission rates
are expected to remain below applicable limits, and continued compliance with 2Q.0711 is expected.
2D.1111 -Maximum Achievable Control Technology-Maximum Achievable Control Technology(MACT)as
promulgated in 40 CFR 63, Subpart XXXXXX, National Emission Standards for Hazardous Air Pollutants Area
Source Standards(NESHAPs)for Nine Metal Fabrication and Finishing Source Categories",for Machining
(§63.11516(b))and Welding(§63.11516(f))processes-Initially,it was interpreted that Altec Industries was subject
to regulation under 40 CFR 63, Subpart XXXXXX which applies to Metal Fabrication and Finishing Sources.
Specifically,the rule applies to facilities that are primarily engaged in metal fabrication and finishing. Operating
standards are required for machining operations that use materials containing metal fabrication and finishing
Hazardous Air Pollutants(MFHAP).
The rule is triggered if the MFHAP contains cadmium,chromium, lead,or nickel in amounts greater than or equal to
0.1 percent by weight,or contains manganese in an amount greater than or equal to 1.0 percent by weight. The
triggering quantity for welding operations is 2,000 pounds per year of welding wire. The Permittee indicated that
well over 2,000 pounds per year of welding wire was used and that the actual manganese content of the electrode
wire was typically between 0.9 and 1.4 percent.
However,it was later determined that neither the facility's Standard Industrial Classification(SIC)code,nor the
North American Industrial Classification System(NAICS)code are not identified in the list of SIC/NAICS code
combination included in Table 1 of the Federal Register(FR)publication of the final rule. Therefore,the facility is j
not subject to the rule. Starting with Air Permit No.09587R02,welding operations are listed as insignificant source
with ID No. IES-WELD.
Compliance History
There have been no air quality compliance issues documented at this facility during the past five years.
Conclusion and Comments
At the time of the partial compliance evaluation,Altec Industries' Burnsville facility appeared to be operating in
compliance with Air Quality Permit 09587R03.
