II.B.2 Contouring and Machining Operations
II.B.2.a The owner/operator shall install and operate a cyclone to control process streams from the
contouring and machining operations. All exhaust air from the contouring and machining
operations shall be routed through the cyclone before being vented to the atmosphere.
[R307-401-8]
Status: In Compliance. Emissions from the contouring and machining operations are
routed through the cyclone before being vented to the atmosphere.
II.B.2.b The owner/operator shall install a manometer or magnehelic pressure gauge to measure the differential pressure across the cyclone. The static pressure differential across the cyclone shall be between 1.0 to 6.0 inches of water column. [R307-401-8] II.B.2.b.1 The pressure gauge shall be located such that an inspector/operator can safely read the indicator at any time. The pressure gauge shall measure the pressure drop in 1-inch water column increments or less. The pressure gauge shall be calibrated according to the manufacturer's instructions at least once every 12 months. [R307-401-8]
II.B.2.b.2 The owner/operator shall record the reading of the pressure gauge at least once per operating day.
[R307-401-8]
Status: In Compliance. A magnehelic pressure gauge is installed and was viewed during
the inspection. The cyclone was undergoing routine maintenance during the site visit and a
daily pressure reading had not been recorded. A measurement from the previous day read
2.3 inches of water column. Readings are recorded daily when the cyclone is in operation.
The pressure gauge was last calibrated in March of 2024.
II.B.3 VOC & HAPs Requirements
II.B.3.a The owner/operator shall not emit more than the following from evaporative sources (solvent
use, mold release, epoxy resin, lubricant use, adhesive, and paints) on site:
11.16 tons per rolling 12-month period of VOCs
0.95 tons per rolling 12-month period of ethyl benzene
0.19 tons per rolling 12-month period of methyl isobutyl ketone
0.28 tons per rolling 12-month period of phenol
2.86 tons per rolling 12-month period of Styrene
0.45 tons per rolling 12-month period of toluene
1.39 tons per rolling 12-month period of xylene
6.15 tons per rolling 12-month period of all HAPs combined. [R307-401-8]
II.B.3.a.1 The owner/operator shall calculate a new 12-month total by the 20th day of each month using
data from the previous 12 months. The owner/operator shall use a mass-balance method to
calculate emissions from evaporative sources. The owner/operator may use the following
equations with applicable units to comply with the mass-balance method:
VOCs = [% VOCs by Weight/100] x [Density] x [Volume Consumed]
HAP = [% HAP by Weight/100] x [Density] x [Volume Consumed]
[R307-401-8]
5
II.B.3.a.2 The owner/operator shall use a mass-balance method to quantify any amount of VOCs and HAPs reclaimed. The owner/operator shall subtract the amount of VOCs and HAPs reclaimed from the
quantities calculated above to provide the monthly total emissions of VOCs and HAPs.
[R307-401-8]
II.B.3.a.3 The owner/operator shall keep records each month of the following:
A. The name (as per SDS) of the VOC- and HAP-emitting material
B. The maximum percent by weight of VOCs and each HAP in each material used
C. The density of each material used
D. The volume of each VOC- and HAP-emitting material used
E. The amount of VOCs and the amount of each HAP emitted from each material
F. The amount of VOCs and the amount of each HAP reclaimed and/or controlled from
each material
G. The total amount of VOCs, the total amount of each HAP, and the total amount of all
HAPs combined emitted from all materials (in tons)
[R307-401-8]
Status: In Compliance. Calculations are made according to this condition. Refer to an
example of these calculations in the attachments. The rolling 12-month totals are as
follows:

0.00 tons of methyl isobutyl ketone
0.04 tons of phenol
0.03 tons of styrene
0.01 tons of toluene
0.17 tons of xylene
0.42 tons of combined HAPs
II.B.3.b The owner/operator shall install and operate a set of paint arrestor particulate filters for each
paint booth to control particulate emissions. All air exiting the booths shall pass through this
control system before being vented to the atmosphere (outside building/operation). The filters
shall be maintained and replaced according to the manufacturer's instructions. [R307-401-8]
Status: In Compliance. Spray booths are equipped with paint arrestor particulate filters.
Air is pulled through the filters before being vented to the atmosphere. Filters are changed
weekly.
II.B.3.c The owner/operator shall store the VOC/HAP containing materials in closed and air tight containers when the materials are not in use. [R307-401-8] Status: In Compliance. VOC/HAP containing materials are kept in closed, air tight containers.

II.B.4 Sanding and Abrasive Blasting Operations
II.B.4.a The owner/operator shall install and operate a baghouse to control process streams from the
sanding and abrasive blasting operations. All exhaust air from the sanding and abrasive blasting
operations shall be routed through the baghouse before being vented to the atmosphere.
[R307-401-8]
Status: In Compliance. Process streams from the sanding and blasting operation are
routed through a baghouse before being vented to the atmosphere.
II.B.4.b The owner/operator shall install a manometer or magnehelic pressure gauge to measure the
differential pressure across the baghouse. The static pressure differential across the baghouse
shall be between 1.0 to 6.0 inches of water column. [R307-401-8]
II.B.4.b.1 The pressure gauge shall be located such that an inspector/operator can safely read the indicator
at any time. The pressure gauge shall measure the pressure drop in 1-inch water column
increments or less. The pressure gauge shall be calibrated according to the manufacturer's
instructions at least once every 12 months. [R307-401-8]
II.B.4.b.2 The owner/operator shall record the reading of the pressure gauge at least once per operating day.
[R307-401-8]
Status: In Compliance. A magnehelic pressure gauge is installed and was viewed during
the inspection. The baghouse was undergoing routine maintenance during the site visit and
a daily pressure reading had not been recorded. A measurement from the previous day
read 2.6 inches of water column. Readings are recorded daily when the baghouse is in
operation. The pressure gauge was last calibrated in March of 2024.
