Project Description
Nucor-Vulcraft requested the addition of a new TrueCore Insulated Panels facility. The TrueCore facility
will manufacture polyisocyanurate foam insulated steel building panels. The production line will operate
8,760 hours per year. The addition of this line will result in an increase in VOCs, HAP (less than .01 tons
per year), PM10, and PM2.5.

The mini-joist line will include dip coatings, welding equipment, and handheld plasma cutters. The mini-
joist will increase structural steel joist assembly by 3,000 tons/year increasing the facility wide total to
154,200 tons/year.

Project Description
Nucor-Vulcraft requested the addition of a new TrueCore Insulated Panels facility. The TrueCore facility
will manufacture polyisocyanurate foam insulated steel building panels. The production line will operate
8,760 hours per year. The addition of this line will result in an increase in VOCs, HAP (less than .01 tons
per year), PM10, and PM2.5.

The mini-joist line will include dip coatings, welding equipment, and handheld plasma cutters. The mini-
joist will increase structural steel joist assembly by 3,000 tons/year increasing the facility wide total to
154,200 tons/year.

Review of BACT for New/Modified Emission Units

1. BACT review regarding TrueCore Insulating Operations and mini-Joist Line
The new TrueCore facility will generate VOC, HAP (Methylenediphenyl diisocyanate(MDI)),
PM10, and PM2.5 emissions.

VOC and HAP controls for the insulation line include a solvent recovery and cooling system, a
thermal oxidizer, and blowing agent selection. A cooling system was ruled technically infeasible
due to the maximum proposed concentration of 4000 ppmv. Industry has determined that waste
streams are effectively at above 5,000 ppmv. Thermal oxidation was evaluated and determined to
be cost prohibitive at $29,000/ton of VOC removed. Assuming 95% efficiency for the 35 tons of
VOCs generated in the process. The cost per ton for the .0065 ton/yr of MDI is cost prohibitive.
BACT for VOCs and HAPs is best management and work practices (including maintaining
equipment; and ensuring mixing and heating operations are maintained according to the
manufacturer's recommendations.)

For PM10 and PM2.5 emissions, the source selected a baghouse. Baghouses are considered the most
efficient control at 99% efficiency and technically feasible. A cost analysis was not conducted,
UDAQ agrees that use of a baghouse to control PM10 and PM2.5 is BACT for this operation.

The mini–joist Line will increase production by 3,000 tons/year of steel processed. Operations for
the mini-joist line include the dip tanks, welding, and handheld plasma cutting. The Joist Plant
Mini-Line expansion will increase emissions of VOC associated with Dip Coating by 1.66
tons/year and increase emissions of PM10 by 0.11 tpy and PM2.5 by 0.06 tpy from welding and hand
held plasma cutting.

Potential add-on controls for the dip tank includes adsorption systems or regenerative thermal
oxidizers. The estimated cost of either adsorption systems or regenerative thermal oxidizer exceeds
$500,000 per ton of VOC emissions removed. The remaining BACT control technologies include
best practices and operations. The source will use Low-VOC primers and optimizing application
techniques.

Potential add-on controls for the welders and handheld plasma guns include baghouse, or ESP.
However, these controls are technically infeasible due to the nature of the handheld mobile
equipment (mobile within the facility). BACT for welding and handheld plasma guns associated
with the mini-joist line is best practices and operations such as process optimization and operator
training to minimize emissions. [Last updated October 25, 2023]

REVIEWER COMMENTS

1. Comment regarding Emission Estimates:
Emissions from the new TrueCore insulation process are generated from tanks, chemical mixing,
adhesion, and cutting.

MDI emissions were calculated using The American Chemistry Council's MDI/PMDI Emission
Calculator.

VOC emissions from the FOAM-line are based on the foam throughput (based on 8,760 hours) and a
5.04% weight conversion for the pentane blowing agent. This is then multiplied by the 5% VOC
release rate as developed by the Urethane Science and Technology - CP Emission Study.

VOC emissions from the MAST are based on a 1.59 lb/gal VOC, 2.11 gallons used per hour, and
8,760 hours of use per year.

PM10 and PM2.5 emissions were based on the percentage of material cut and a 99.9% control
efficiency.

Emissions from the new mini-joist line include dip coating, welding, and handheld plasma guns.

PM10 and PM2.5 emissions from plasma cutters were based on emission factors and calculations from
“Emission of Fume, nitrogen oxides, and noise in plasma cutting of stainless and mild steel",
Bramsen B. et al., Sweden 1994.

PM10 and PM2.5 emissions from welding were based on the material emission factors and volume
welded.

VOC emissions form the dip tanks were based mass balance.

2. Comment regarding New Facility Explanation:
The process involves pre-heating, adhesion improvement, heating, sealing, and trimming, with
emissions directed through Stack FOAM-1 and dust collection via DC-01.

Steel coils are pre-heated in an oven and undergo a high-voltage purification treatment ("Corona
Treatment") to improve foam adhesion. The FOAM-1 line mixes the liquid components and inserts
the chemicals between upper and lower facers to create solid foam panels. The specific mixture used
depend on the panel type to be generated. The foam is then injected between the panels and then

October 25, 2023
Page 17
heated further in the Laminator Heater at 150-200F. Emissions are directed through the stack.

Mastic is applied to one panel edge to create a watertight seal, entrapping some air pollutants,
however there are some fugitive emissions due to the nature/size of the process. The foamed/
insulated panel then goes to the saw house for trimming. Dust and particles generated in this process
are collected by DC-01, a dust collector with a 99.9% control efficiency, exhausting into the plant
interior.

The source has selected to use pentane as their blowing agent. Other blowing agents could reduce
the VOC emissions from the process but could result in lower R-values (insulating strength).
Additionally, using agents such as carbon dioxide could increase CO2e emissions.

origin to the point where the water content reaches 99%. For water streams with a water content greater then 99%
emissino rate is considered negligible.
The "other" equipment type was derived from compressors, diaphrams, drains, dump arms, hatches, instruments,
pressure relief valves, polished rods, relief valves, and vents. This "other" equipment type should be applied for an
equipment type other then connectors, flanges, open-ended lines, pumps, or valves.

Project Proposal
Modification to Approval Order DAQE-AN100280018-23 to Add a New TrueCore Insulated
Panels Process and a Mini-Joist Line

Project Description
Nucor-Vulcraft requested the addition of a new TrueCore Insulated Panels facility. The TrueCore
facility will manufacture polyisocyanurate foam insulated steel building panels. The production
line will operate 8,760 hours per year. The addition of this line will result in an increase in VOCs,
HAP (less than .01 tons per year), PM10, and PM2.5.

The mini-joist line will include dip coatings, welding equipment, and handheld plasma cutters.
The mini-joist will increase structural steel joist assembly by 3,000 tons/year increasing the
facility wide total to 154,200 tons/year.

Review of BACT for New/Modified Emission Units

1. BACT review regarding TrueCore Insulating Operations and mini-Joist Line
The new TrueCore facility will generate VOC, HAP (Methylenediphenyl diisocyanate(MDI)),
PM10, and PM2.5 emissions.

VOC and HAP controls for the insulation line include a solvent recovery and cooling system, a
thermal oxidizer, and blowing agent selection. A cooling system was ruled technically infeasible
due to the maximum proposed concentration of 4000 ppmv. Industry has determined that waste
streams are effectively at above 5,000 ppmv. Thermal oxidation was evaluated and determined to
be cost prohibitive at $29,000/ton of VOC removed. Assuming 95% efficiency for the 35 tons of
VOCs generated in the process. The cost per ton for the .0065 ton/yr of MDI is cost prohibitive.
BACT for VOCs and HAPs is best management and work practices (including maintaining
equipment; and ensuring mixing and heating operations are maintained according to the
manufacturer's recommendations.)

For PM10 and PM2.5 emissions, the source selected a baghouse. Baghouses are considered the most
efficient control at 99% efficiency and technically feasible. A cost analysis was not conducted,
UDAQ agrees that use of a baghouse to control PM10 and PM2.5 is BACT for this operation.

The mini–joist Line will increase production by 3,000 tons/year of steel processed. Operations for
the mini-joist line include the dip tanks, welding, and handheld plasma cutting. The Joist Plant
Mini-Line expansion will increase emissions of VOC associated with Dip Coating by 1.66
tons/year and increase emissions of PM10 by 0.11 tpy and PM2.5 by 0.06 tpy from welding and hand
held plasma cutting.

Potential add-on controls for the dip tank includes adsorption systems or regenerative thermal
oxidizers. The estimated cost of either adsorption systems or regenerative thermal oxidizer exceeds
$500,000 per ton of VOC emissions removed. The remaining BACT control technologies include
best practices and operations. The source will use Low-VOC primers and optimizing application
techniques.

Potential add-on controls for the welders and handheld plasma guns include baghouse, or ESP.
However, these controls are technically infeasible due to the nature of the handheld mobile
equipment (mobile within the facility). BACT for welding and handheld plasma guns associated
with the mini-joist line is best practices and operations such as process optimization and operator
training to minimize emissions. [Last updated October 25, 2023]

REVIEWER COMMENTS

1. Comment regarding Emission Estimates:
Emissions from the new TrueCore insulation process are generated from tanks, chemical mixing,
adhesion, and cutting.

MDI emissions were calculated using The American Chemistry Council's MDI/PMDI Emission
Calculator.

VOC emissions from the FOAM-line are based on the foam throughput (based on 8,760 hours) and a
5.04% weight conversion for the pentane blowing agent. This is then multiplied by the 5% VOC
release rate as developed by the Urethane Science and Technology - CP Emission Study.

VOC emissions from the MAST are based on a 1.59 lb/gal VOC, 2.11 gallons used per hour, and
8,760 hours of use per year.

PM10 and PM2.5 emissions were based on the percentage of material cut and a 99.9% control
efficiency.

Emissions from the new mini-joist line include dip coating, welding, and handheld plasma guns.

PM10 and PM2.5 emissions from plasma cutters were based on emission factors and calculations from
“Emission of Fume, nitrogen oxides, and noise in plasma cutting of stainless and mild steel",
Bramsen B. et al., Sweden 1994.

PM10 and PM2.5 emissions from welding were based on the material emission factors and volume
welded.

VOC emissions form the dip tanks were based mass balance.

[Last updated October 11, 2023]

2. Comment regarding New Facility Explanation:
The process involves pre-heating, adhesion improvement, heating, sealing, and trimming, with
emissions directed through Stack FOAM-1 and dust collection via DC-01.

Steel coils are pre-heated in an oven and undergo a high-voltage purification treatment ("Corona
Treatment") to improve foam adhesion. The FOAM-1 line mixes the liquid components and inserts
the chemicals between upper and lower facers to create solid foam panels. The specific mixture used
depend on the panel type to be generated. The foam is then injected between the panels and then

Engineer Review N100280019: Vulcraft
- Division of Nucor Corporation - Steel Products Manufacturing
October 25, 2023
Page 17
heated further in the Laminator Heater at 150-200F. Emissions are directed through the stack.

Mastic is applied to one panel edge to create a watertight seal, entrapping some air pollutants,
however there are some fugitive emissions due to the nature/size of the process. The foamed/
insulated panel then goes to the saw house for trimming. Dust and particles generated in this process
are collected by DC-01, a dust collector with a 99.9% control efficiency, exhausting into the plant
interior.

The source has selected to use pentane as their blowing agent. Other blowing agents could reduce
the VOC emissions from the process but could result in lower R-values (insulating strength).
Additionally, using agents such as carbon dioxide could increase CO2e emissions.

1.0 INTRODUCTION

Vulcraft - Division of Nucor Corporation (Vulcraft) is providing the necessary documentation and
information for Utah Division of Air Quality (UDAQ) to process this Notice-of-Intent (NOI), based
on Utah Rule 307-100-12. This NOI involves the following additions and modifications:

1. Addition of a “Mini-Line” installation (Joist Plant). Operation of the Mini-Line will result in a
3000 ton/year increase in steel joist production (154,200 tons/year versus the current
151,200 tons/year limit in RN100280018.23 Section II.B.1.a.B).
Nucor Corporation will operate four (4) processing and fabrication divisions at its Brigham City
operation that operate under the following SICs:

1) Vulcraft Joist Plant (SIC 3441);
2) Cold Finish Division (SIC 3316);
3) Nucor Building Systems (SIC 3448); and
4) TrueCore Insulated Panels (SIC 5033)

If considered one source, the most comprehensive Standard Industrial Classification (SIC) code is
3441.

The Nucor productions buildings (Structural Products/Joist/Cold Finish/NBS) are located at 1875
West Highway 13 South, Brigham City, Utah. TrueCore will maintain street address 1101 N. Watery
Lane, Brigham City, UT. The global location, considering the center of the Joist Plant is: 411 .5 km
Easting, 4598 km Northing, UTM Zone 12 UTM Datum: NAD27 (see Figure 1). Figure 1 also
shows the building locations and emission unit locations for these proposed modifications.

This NOI compares the AN100280015-19 Potential-to-Emit (PTE) to the new Potential to Emit
(PTE) and is inclusive of emissions contained in the May 15, 2023 NOI for TrueCore operations as
well as the proposed Mini-Line operation. This comparison involves only Volatile Organic
Compounds (VOC), PM10 and PM2.5, nitrogen oxides (NOx), Ozone and HAP (MDI). All other
Criteria pollutants and Greenhouse Gases (GHGs) remain at the existing permitted and calculated
levels. As such, this NOI is considered a Minor Modification to a Major Source. The following
information is provided as part of this NOI in accordance with the requirements of UDAQ Air
Quality Regulations R307-401-5.

2.0 PROCESS DESCRIPTION

The Joist Plant Mini-Line will produce very small joist products as needed to alleviate congestion
on larger joist assemblies in the overall Joist Plant operation but will potentially increase
production by 3,000 tons/year. Operations associated with the Mini-Line consist of rigging,
welding, dip coating and handheld plasma cutting. Emission estimates for the addition of the Mini-
Line have been estimated based on current emissions scaled up for the potential increase in
production.

Mobile handheld plasma cutters are used throughout the Joist Plant for detailed production
purposes. Emissions from handheld plasma cutters are now quantified based on production limits
and listed as specific emission sources within emission calculations.

3.0 EMISSIONS

Potential-to-Emit (PTE) for the proposed operations are found in Appendix A. The emissions are
based on existing maximum operating schedules and equipment design capabilities. The permitted
PTE emissions, proposed PTE emissions and the net change emissions are shown in Table 3-1.

3.1 PSD and Offset Applicability

The Vulcraft facility is located in Box Elder County, which is Serious NAA for PM2.5. Vulcraft has
historically considered PSD offsets because of being listed as subject to the PSD program due to
volatile organic compounds (VOC) greater than 250 tpy. Based on conversations with DAQ in June
2021, the facility is no longer considered major for PSD as VOC emissions are below the 250 tpy
threshold. Regardless, the projected predictable actual emissions of regulated NSR pollutants from
the proposed processes are as follows:

This comparison table demonstrates that VOC emission increases from the project are less than
significant, do not constitute a Major Modification, and do not require offsets. This is considered a
Minor Modification because PTE is changing, and new equipment is being permitted, but potential
emission increases are below Major Modification thresholds.

• R307-410-5 Documentation of Ambient Air Impacts for Hazardous Air Pollutants requires
any source submitting a NOI, which proposes to increase emission of HAP, to use Table 2
in the rule to determine whether or not a dispersion modeling analysis of each pollutant is
required as part of a complete NOI (see Section 4.6 - Documentation of Ambient Air
Impacts for Hazardous Air Pollutants).
• Utah 2016 PM2.5 SIP - Box Elder County is Serious NAA for PM2.5

4.4 Best Available Control Technology (BACT) Analysis

Best Available Control Technology (BACT) analysis was performed as required by New Source
Review (NSR). BACT analysis is required for all new or modified sources for all pollutants not
previously emitted or whose emissions would increase because of the new source or modification.

The RACT/BACT/LAER (RBLC) Clearinghouse is a database maintained by the US EPA that provides
information on Best Available Control Technology (BACT) for controlling emissions from similar
sources that use pentane related materials as the blowing agent. The Clearinghouse contains
information on BACT determinations made by state and local air pollution control agencies, as well
as EPA determinations for certain industries.
The Joist Plant Mini-Line expansion will increase emissions of VOC associated with Dip Coating by
1.66 tons/year, and increase emissions of PM10 and PM2.5 associated with welding and hand held
plasma cutting by 0.11 and 0.06 tons/year, respectively. NOx emissions from hand held plasma
cutting operations do not increase over previous estimates. Inclusive of emissions from the May
15, 2023 NOI for TrueCore operations, facility wide VOC increases are 36.79 tons/year. PM10 and
PM2.5 are 0.12 and 0.07 tons/year, respectively.

Control technologies identified for VOC generated by primer dip coating include the following:

1. Low VOC Primers: Use of primers with lower VOC content to reduce emissions during the
coating process. Dip coating primers are currently 0.85 lb VOC/gal.
2. Emission Controls: Installation of air pollution control equipment, such as adsorption
systems or regenerative thermal oxidizers, to capture and treat VOC emissions before they are
released into the atmosphere. The installation of a thermal oxidizer is effective in VOC
destruction albeit with high total installed cost ($867,000-$998,000) and annual operating cost
($33,500-$41,800). At the higher end, cost per ton VOC removed is $626,385/ton versus
average industry costs ranging from $1,000 to $5,000 per ton of VOC removed.

3. Process Optimization: Implementation of process modifications and operational practices to
reduce VOC emissions, such as optimizing application techniques (dip coating) and minimizing
overspray (not appliable to immersion dip coating).

This NOI proposes that BACT for dip coating operations is low VOC primers and process
optimization.

Control technologies identified for particulate matter (PM) generated by plasma cutting are
typically fabric filters or baghouse apparatuses. However, given that handheld plasma cutting is
mobile in nature while most fume collection systems are not, this NOI proposes that BACT is process
optimization and operator training to minimize emissions.

4.5 BACT Conclusion

BACT for dip coating operations is low VOC primers and process optimization. BACT for handheld
plasma cutting is process optimization and operator training to minimize emissions.

1.0 INTRODUCTION

Vulcraft - Division of Nucor Corporation (Vulcraft) is providing the necessary documentation and
information for Utah Division of Air Quality (UDAQ) to process this Notice-of-Intent (NOI), based
on Utah Rule 307-100-12. This NOI involves the addition of a separate business unit, TrueCore, a
Nucor Company (TrueCore). The TrueCore operation will be located within a separate building as
indicated in the attached Figure 1 Site Plan.

TrueCore will be co-located with the Vulcraft - Division of Nucor Corporation operations. The Utah
Division of Air Quality has assigned the Site ID of 10028 to Vulcraft, which is a Title V Major
Source. The facility is permitted under AO AN100280015-19 (currently out for public comment).
The Title V Permit number for Vulcraft is #300030004. Located in Box Elder County, this airshed is
Serious NAA for PM2.5.

Nucor Corporation will operate four (4) processing and fabrication divisions at its Brigham City
operation that operate under the following SICs:

1) Vulcraft Joist Plant (SIC 3441);
2) Cold Finish Division (SIC 3316);
3) Nucor Building Systems (SIC 3448); and
4) TrueCore Insulated Panels (SIC 5033)

If considered one source, the most comprehensive Standard Industrial Classification (SIC) code is
3441.

The TrueCore facility will manufacture polyisocyanurate foam insulated steel building panels. The
foam insulated panel line will be designated as “FOAM-1” Line. The insulated foam panels are
used in commercial cold storage applications. The TrueCore facility operates under the North
American Industrial Classification System (NAICS) Code of 423330 and Standard Industrial
Classification (SIC) Code of 5033 Roofing, Siding, and Insulation Materials. The production line is
expected to operate 4,800 hours per year, which averages 20 hours per day, 5 days per week, 50
weeks per year.

Operations to be conducted on-site include foam production, panel cutting and trimming activities
and corona treatment to promote foam adhesion to the steel panels.

This NOI compares the AN100280015-19 Potential-to-Emit (PTE) to the new calculated PTE. This
comparison involves only Volatile Organic Compounds (VOC), PM10 and PM2.5, nitrogen oxides
(NOx), Ozone and HAP (MDI). All other Criteria pollutants and Greenhouse Gases (GHGs) remain
at the existing permitted and calculated levels. As such, this NOI is considered a Minor Modification
to a Major Source. The following information is provided as part of this NOI in accordance with the
requirements of UDAQ Air Quality Regulations R307-401-5.

The Nucor productions buildings (Structural Products/Joist/Cold Finish/NBS) are located at 1875
West Highway 13 South, Brigham City, Utah. TrueCore will maintain street address 1101 N. Watery
Lane, Brigham City, UT. The global location, considering the center of the Joist Plant is: 411 .5 km
Easting, 4598 km Northing, UTM Zone 12 UTM Datum: NAD27 (see Figure 1). Figure 1 also
shows the building locations and emission unit locations for these proposed modifications.

2.0 PROCESS DESCRIPTION

TrueCore will use three main raw materials in the production of foam insulated panels:
methyldiisocyanate (MDI), Polyol, and a Hydrocarbon Blowing Agent (n-pentane). Several catalysts
and fire retardants may also be used depending upon the type of foam board being produced.

The main raw materials are all liquids and are stored on-site in bulk tanks ranging in size from four
(4) 6,000 gallon vertical storage tanks (MDI and Polyol, 2 each) and a 12,200 gallon underground
storage tank (Pentane Blowing Agent). The liquids flow through a series of static mixers via high
pressure pumps and are combined together and injected between the top and bottom facers at the
Pour Table of FOAM-1. TrueCore will use several different types of facers, depending upon the type
of foam insulated panel being produced. As these liquids combine at the Pour Table, they react to
form a solid foam. As the exothermic reaction occurs, off gassing will result in a release of Volatile
Organic Compounds (i.e. n-pentane emissions) and Hazardous Air Pollutants (MDI) which will
exhaust through Stack FOAM-1.

The continuous length of foam insulated panels produced at the Pour Table begin with upper and
lower steel coils entering the electric infrared pre-heating oven and Corona Treatment. The pre-
heating oven acts to pre-heat upper and lower steel coils prior to the application of foam, while the
Corona Treatment system employs high voltage to improve adhesion of the foam mixture to the
surface of the upper and lower panels.

After exiting the pre-heating oven, the foam mixture is then applied between the upper and lower
panels and the continuous length of panel enters the Laminator Heater. The Laminator Heater is an
electric oven which acts to further solidify and harden the foam. The Laminator Heater normally
operates at temperatures between 150°F and 200°F.

Post Laminator Heater, a bead of mastic is applied to one edge of the panel. The mastic helps create
an impenetrable water and vapor seal for select panel applications. VOC emissions from the mastic
will be exhausted inside the building. TrueCore anticipates emissions will exit the building primarily via
FOAM-1, but minor amounts may exit through doors or other building openings.

Next, the continuous length of the panel enters the saw house. This is an enclosed area where the
board is trimmed to the desired length via cross-cut saw. Emissions are captured via dust collector
DC-01. The edges are also trimmed and collected in dust collector DC-01. All particulate matter
(PM) associated with the cross-cut sawing and edge trimming will be captured via an Oneida Dust
Collector System, DC-01 exhausting through a bin vent to the plant interior. The dust collector has
a 99.9% control efficiency rating.

3.0 EMISSIONS

Potential-to-Emit (PTE) for the proposed operations are found in Appendix A. The emissions are
based on existing maximum operating schedules and equipment design capabilities. The permitted
PTE emissions, proposed PTE emissions and the net change emissions are shown in Table 3-1.

Table 3-1: Allowable (as Contained in AN-100280015-19 Mod 3/13/2023) and
Proposed Emissions

Pollutant Permitted (tpy) Proposed (tpy) Net Change (tpy)

0.0
* Includes filterable, condensable and fugitives
**UDAQ agreed upon limit; total HAPs sums to less than Major Source threshold

3.1 PSD and Offset Applicability

The Vulcraft facility is located in Box Elder County, which is Serious NAA for PM2.5. Vulcraft has
historically considered PSD offsets because of being listed as subject to the PSD program due to
volatile organic compounds (VOC) greater than 250 tpy. Based on conversations with DAQ in June
2021, the facility is no longer considered major for PSD as VOC emissions are below the 250 tpy
threshold. Regardless, the projected predictable actual emissions of regulated NSR pollutants from
the proposed processes are as follows:

Table 3-2: PSD and Offset Applicability

Pollutant New Emissions
(tpy)
Major Modification Threshold
(tpy)
Offset Threshold (tpy)
NOx 0.0 40 40
CO 0.0 100
SO2 0.0 40 40
PM10 0.01 15
PM2.5 0.01 10 10
VOC 35.22 40 40

This comparison table demonstrates that VOC emission increases from the project are less than
significant, do not constitute a Major Modification, and do not require offsets. This is considered a
Minor Modification because PTE is changing, and new equipment is being permitted, but potential
emission increases are below Major Modification thresholds.

4.4 Best Available Control Technology (BACT) Analysis

Best Available Control Technology (BACT) analysis was performed as required by New Source
Review (NSR). BACT analysis is required for all new or modified sources for all pollutants not
previously emitted or whose emissions would increase because of the new source or modification.

The RACT/BACT/LAER (RBLC) Clearinghouse is a database maintained by the US EPA that provides
information on Best Available Control Technology (BACT) for controlling emissions from similar
sources that use pentane related materials as the blowing agent. The Clearinghouse contains
information on BACT determinations made by state and local air pollution control agencies, as well
as EPA determinations for certain industries.
Based on a review of the Clearinghouse, several BACT options have been identified for controlling
VOC emissions from polyurethane foam insulated structural panel process lines that use pentane
as the blowing agent. These options include:
1. Use of a non-VOC blowing agent, such as carbon dioxide or water.
2. Use of a low-VOC blowing agent, such as a hydrofluoroolefin (HFO).
3. Installation of a thermal oxidizer to destroy VOC emissions.
4. Implementation of a solvent recovery system to capture, condense and potentially reuse
pentane.
5. Implementation of a VOC emissions reduction plan, which may include process
modifications, equipment upgrades, and/or operational changes.
The specific BACT option(s) that should be selected for a polyisocyanurate foam insulated
structural panel process line that uses pentane as the blowing agent and has VOC emissions of
approximately 35.13 tons/yr will depend on several factors, including the feasibility and cost-
effectiveness of each option.

Vulcraft-TrueCore NOI May 2023
Page 7 of 8

H:\Data\V\Vulcraft - Div of Nucor Corp\VUL0002.AC - Air Compliance Brigham City Utah\WP\Vulcraft-TrueCore UT NOI 05-09-2023.docx
The use of a non-VOC or low-VOC blowing agent is an effective means of reducing VOC emissions
from this process, but technically infeasible due to chemical compatibility and equipment
interaction.

The installation of a thermal oxidizer is effective in VOC destruction albeit with high total installed
cost ($867,000-$998,000) and annual operating cost ($33,500-$41,800). At the higher end, cost
per ton VOC removed is $29,598/ton versus average industry costs ranging from $1,000 to $5,000
per ton of VOC removed.

The installation of a solvent recovery system is technically and financially infeasible as refrigerated
condensers are typically used to control waste streams with VOC concentrations above 5,000 ppmv
(TrueCore exhaust concentrations will be less than 4000 ppmv). The total capital investment is
estimated at $4,491,000. The required refrigeration capacity (421.5 tons/hour) would cost
$1,350,000 annually.

Control technologies identified for particulate matter (PM) generated by panel sawing operations
all involve fabric filters or baghouse apparatuses. Collection (capture efficiency) of emissions is a
significant factor in choosing the most control and cost-effective option. Using different cartridges
or bags could be considered, but the amount of PM less than 0.5 μm generated by these
operations is characterized as insignificant. Removal of an additional thousandths of a ton is not
cost effective and does not include additional mitigation of environmental impacts.

For panel sawing PM emissions, this modification proposes dust collection systems that allows
operations to be safely exhausted indoors.

Energy Impacts – Energy impacts associated with thermal oxidation are significant. As the foam
manufacturing process line is electrically driven with motors specifically sized for operations, and
the oven is also electrical, process energy impacts are as minimal as possible. However, energy
cost and fuel requirements associated with add-on thermal oxidation total $40,100 in direct annual
cost.

The proposed Dust Collector at the TrueCore operation is electrically driven with a motor
specifically sized for the operation. Energy impacts are as minimal as possible given the type and
volume of this operation.

Environmental Impacts - There are adverse environmental impacts associated with the use of
oxidation technologies. Oxidation of VOC emissions and combustion of fuel would lead to increased
NOx , CO2 and PM emissions that would contribute to increased ozone formation and PM loading
in the region.

Economic Impact - Capital costs for control of foam production with a standalone thermal
oxidizer were estimated using the EPA Air Pollution Control Cost Manual and associated Estimation
Spreadsheet for Thermal Oxidizers and Incinerators. The cost estimate presented a capitol cost of
$867,000-$998,000 and annual operating cost of $33,500-$41,800. The estimated cost
effectiveness for the control option is approximately $29,598 per ton of VOC. This value is above
reasonable cost effectiveness value for VOC control when add-on controls are considered. In this
analyses, VOC controls that are $6,000/ton - $11,998/ton are identified.

H:\Data\V\Vulcraft - Div of Nucor Corp\VUL0002.AC - Air Compliance Brigham City Utah\WP\Vulcraft-TrueCore UT NOI 05-09-2023.docx
Other Considerations - Reductions of particulate emissions from panel sawing are at levels that
allow for indoor release of particulates proving air pollution impacts are insignificant.

The RBLC was queried for key words “foam” and “SIC Code 3086 Plastic Foam Products” for the US,
Canada and Mexico from January 1, 2013 to present. The results indicate that management
practices and thermal oxidation are the preferred BACT. Please note that many of the sites
included in RBLC query the produce flexible or polystyrene foam and not the rigid polyisocyanurate
insulated foam panels like TrueCore.

The query result of PM for sawing operations lists baghouses as the only control technology.

Baghouses with 99.0% and 99.9% control of PM10, and PM2.5 respectfully, are considered BACT
for sawing operations.

This enclosed BACT effort was finalized in April 2023. The listing from EPA’s RACT/BACT/LEAR
Clearinghouse is found in Appendix C.

4.5 BACT Conclusion

Management and work practices as well as monitoring and reporting VOC emission are considered
BACT for VOC emissions associated with FOAM-1 Line operations as thermal oxidation technologies
exceed

Dust collection systems via baghouse and cartridge filter systems are considered BACT for
controlling PM emissions from panel sawing operations. Economic and energy impacts are nominal
and do not influence this determination; as these control devices are electrically driven devices
with no additional pollutants generated due to their operation. The capture efficiency of particulate
matter is nearly 100% due to the design of the process systems utilizing the dust collection
devices. The removal efficiency of captured particulate matter due to the emission control systems
is 99.9% based on vendor specifications. These control devices are considered the most efficient,
effective systems for control of emissions from panel sawing operations.

4.6 Documentation of Ambient Air Impacts for Hazardous Air Pollutants (MDI)

In accordance with guidance DAQ-2018-0022269, R307-410-5 requires any source submitting a
NOI, which proposes to increase emission of HAP, to use Table 2 in the rule to determine whether
or not a dispersion modeling analysis of each pollutant is required as part of a complete NOI. If
new emissions of the HAP (expressed in lb/hr) exceeds the emission threshold value, dispersion
modeling is required.

MDI – 13 lb/yr ÷ 4160 hr/yr = 0.00313 lb/hr

When selecting the proper Emission Threshold Factor, the following release scenario should be
determined as follows:

"Vertically Restricted Emissions Release" means the release of an air contaminant through a stack
or opening whose flow is directed in a downward or horizontal direction due to the alignment of
the opening or a physical obstruction placed beyond the opening, or at a height which is less than
1.3 times the height of an adjacent building or structure, as measured from ground level.
Vulcraft-TrueCore NOI May 2023
Page 9 of 8

H:\Data\V\Vulcraft - Div of Nucor Corp\VUL0002.AC - Air Compliance Brigham City Utah\WP\Vulcraft-TrueCore UT NOI 05-09-2023.docx
"Vertically Unrestricted Emissions Release" means the release of an air contaminant through a
stack or opening whose flow is directed upward without any physical obstruction placed beyond
the opening, and at a height which is at least 1.3 times the height of an adjacent building or
structure, as measured from ground level.

The user should identify the proper venting classification (from the two listed above) and the
distance of the stack or emission release point to the nearest property boundary.

The majority of MDI emission will be generated at the pour table and exhausted via
18” vertical exhaust extending vertically through the 31’ eave height with a 10’ stack
extension (41’ above grade). The distance from the emission point to the nearest
property line is approximately 375 meters.

The MDI Chronic Emission Threshold Value (lb/hr) for Vertically Unrestricted Releases
>100 meters from property lines is 0.019 lb/hr.

0.019 lb/hr > 0.00313, therefore dispersion modeling is not required.

AVAILABILITY OF VARIOUS OPTIONS
The available options mainly belong to three categories of chemicals viz. HCFCs, HFCs and
hydrocarbons. Table 5 highlights the status of commercial availability of the available options
[10].
Table 5. Commercial Availability of Available Options
Option ShortTerm 1993-1995 Long Term 1995-2000
Cyclopentane Adequate Likely to ease further as
production builds
HCFC-141b Adequate Uncertain, depending on
progress made with the
development of replacement
products now emerging. In any
case, likely to be from
developed countries only
HCFC-142b Adequate Adequate-likely to be from
developed countries only
HCFC-22 Good Good-mainly from developed
countries. Chinese and Indian
Production probable
HFC-134a Adequate-could be tight Good-likely to be from
developed countries only
Isopentane Good Good
CFC-11 Good, but developed country Tight, relying on developing
production will run down from country production. Montreal
1/1/94 Protocol allowances from
developed country suppliers
may not be taken up because of
environmental positioning
The HCFCs are only an interim solution because of the reason that they also have to be phased
out in near future. As per the Copenhagen Amendments, HCFCs will be controlled as follows:
Freeze in 1996 at 3.1% of calculated level of CFCs consumption plus calculated level of
HCFCs in 1989;
35% reduction by 2004;
65% reduction by 2010;
90% reduction by 2015;
99.5% reduction by 2020; and
100% reduction by 2030.

AVAILABILITY OF CYCLOPENTANE, SYSTEMS AND EQUIPMENTS
Availability of Cyclopentane
Cyclopentane is present in natural hydrocarbon sources and can be separated by fractional
distillation (refineries) and is also formed as a byproduct in the processing of cracking products,
e.g. by hydrogenation of cyclopentene in the C fractions of steam cracking products. It can also5
be manufactured by the hydrogenation of cyclopentanone or thermal dehydrogenation of
cyclohexane. Cyclopentane is in production in several European plants and is available in
industrial amounts with a requisite purity level. In the near future, the production of
cyclopentane is expected to increase depending on the demand. The technical specifications of
commercially available cyclopentane is given in Appendix A1.
Table 6 gives the list of potential suppliers of cyclopentane (alphabetical sequence) [2,8].

Using the EPA Air Pollution Control Cost Manual Sixth Edition, Section 3.2 Chapter 2, the cost
estimate for a thermal oxidizer can be calculated as follows:
1. Determine the equipment factor (EF):
EF = (VOC loading rate, lb/hr) / (flow rate, cfm) ^ 0.8
EF = (10.2 lb/hr) / (6,000 cfm) ^ 0.8
EF = 0.00066
2. Determine the bare module cost (BMC) from Table 3-2:
BMC = $106,000 (1999 dollars)
3. Adjust BMC for inflation using the Chemical Engineering Plant Cost Index (CEPCI) for
process equipment:
CEPCI 1999 = 386.5
CEPCI 2023 (estimated) = 679.2 (based on the average of the first three months of 2023)
Inflation factor = (CEPCI 2023 / CEPCI 1999) = (679.2 / 386.5) = 1.758
BMC (2023 dollars) = BMC (1999 dollars) x inflation factor
BMC (2023 dollars) = $106,000 x 1.758
BMC (2023 dollars) = $186,948
4. Determine the total installed cost (TIC) using Equation 3-3:
Direct cost multiplier = 1.88 for a 6,000 cfm unit
Indirect cost multiplier = 1.63 for a thermal oxidizer
TIC (2023 dollars) = BMC (2023 dollars) x (Direct cost multiplier + Indirect cost
multiplier)
TIC (2023 dollars) = $186,948 x (1.88 + 1.63)
TIC (2023 dollars) = $867,176
5. To calculate the AOC, we will use the following equation:
AOC = 0.077 * TCC * (1 + 0.45 * F)
6. Using the TCC value we calculated above, we get:
AOC = 0.077 * $365,000 * (1 + 0.45 * 1.56) AOC = $41,800 per year (in 2023 dollars)
Therefore, the estimated cost for a thermal oxidizer with a flow rate of 6,000 cfm and a VOC
loading of 10.2 lbs per hour is $867,176 in 2023 dollars, after adjusting for inflation from 1999
dollars to 2023 dollars using the CEPCI. Annual operating cost is $41,800. Please note that this
is an estimate and actual costs may vary based on several factors including location, design,
and installation requirements.

Make certain enough air volume is at the suction point to capture all the particulate generated.This high air volume will dilute the mixture below the lower limit of ƀamability. Be careful not to generate sparks into the sanding dust.Empty dust bin and clean ſlter often, especially when sand-ing.Don't overload woodworking equipment, especially sanders.
Excessive frictional heat can spontaneously ignite dust.

Fire Hazards / Risques D’incendie

Wood shaping and cutting processes generate wood
chips, shavings and dust. These materials are consid-
ered combustible. Air borne wood dust below 420 mi-
crons in size (0.17 of an inch) in certain concentration
ranges when ignited can deƀagrate (burn quickly).
An ignition source such as a spark or ember can ignite
a dust mixture resulting in an expanding ƀame front,
which can cause an explosion if tightly contained. A
disturbance that raises a cloud of accumulated ſne
dust can raise additional dust clouds, which can cause
a series of explosions that can level an entire building.
Until this type of ſre has been witnessed, it is difſcult
to beleive the devastation. This type of ſre is rare but
worth safeguarding against.
The best way to avoid a wood shop ſre is to keep the
shop clean. A shop ankle deep in dust with layers of
ſne dust everywhere is an accident waiting to happen.
A good dust collection system reduces overall ſre
hazards but also adds new concerns. A ſre hazard is
still present. Combustible material is now in the dust
collector and storage container.

SECTION 4. FIRST AID MEASURES
General advice

: Move out of dangerous area.
Do not leave the victim unattended.
Get medical attention immediately if symptoms occur.
Show this safety data sheet to the doctor in attendance.

If inhaled

: If breathed in, move person into fresh air.
Call a physician or poison control centre immediately.
Keep patient warm and at rest.
Keep respiratory tract clear.
If breathing is difficult, give oxygen.
If breathing is irregular or stopped, administer artific ial
respiration.
If unconscious, place in recovery position and seek medical
advice.
Consult a physician immediately if symptoms such as
shortness of breath or asthma are observed.
A hyper-reactive response to even minimal concentrations of
diisocyanates may develop in sensitised persons.
The exposed person may need to be kept under medical
surveillance for 48 hours.
LC50 (rat) : ca. 490 mg/m³ (4 hours) : using experimentally
produced respirable aerosol having aerodynamic diameter
<5microns.

In case of skin contact

: In case of contact, immediately flush skin with soap and plenty
of water.
Take off contaminated clothing and shoes immediately.
Wash contaminated clothing before reuse.
Thoroughly clean shoes before reuse.
Call a physician if irritation develops or persists.
An MDI study has demonstrated that a polyglycol-based skin
cleanser (such as D-TamTM, PEG-400) or corn oil may be
more effective than soap and water.

In case of eye contact

: Rinse immediately with plenty of water, also under the eyelids,
for at least 15 minutes.
If easy to do, remove contact lens, if worn.
Protect unharmed eye.
Keep eye wide open while rinsing.
If eye irritation persists, consult a specialist.

If swallowed

: Gently wipe or rinse the inside of the mouth with water.
DO NOT induce vomiting unless directed to do so by a
physician or poison control center.
Keep respiratory tract clear.
Keep at rest.
If a person vomits when lying on his back, place him in the
recovery position.
Never give anything by mouth to an unconscious person.
Take victim immediately to hospital.

If symptoms persist, call a physician.

Most important symptoms
and effects, both acute and
delayed

: Severe allergic skin reactions, bronchiospasm and
anaphylactic shock
This product is a respiratory irritant and potential respiratory
sensitiser: repeated inhalation of vapour or aerosol at levels
above the occupational exposure limit could cause respiratory
sensitisation.
Symptoms may include irritation to the eyes, nose, throat and
lungs, possibly combined with dryness of the throat, tightness
of chest and difficulty in breathing.
The onset of the respiratory symptoms may be delayed for
several hours after exposure.
A hyper-reactive response to even minimal concentrations of
MDI may develop in sensitised persons.

Protection of first-aiders

: No action shall be taken involving any personal risk or without
suitable training.
It may be dangerous to the person providing aid to give
mouth-to-mouth resuscitation.
If potential for exposure exists refer to Section 8 for specific
personal protective equipment.
First Aid responders should pay attention to self-protection
and use the recommended protective clothing

Notes to physician

: Symptomatic and supportive therapy as needed. Following
severe exposure medical follow-up should be monitored for at
least 48 hours.

The first aid procedure should be established in consultation
with the doctor responsible for industrial medicine.

SECTION 5. FIREFIGHTING MEASURES
Suitable extinguishing media

: Use extinguishing measures that are appropriate to local
circumstances and the surrounding environment.

Carcinogenicity
Product:
Remarks: Rats have been exposed for two years to a respirable aerosol of polymeric MDI which
resulted in a chronic pulmonary irritation at high concentrations. Only at the top level (6 mg/m3),
there was a significant incidence of a benign tumour of the lung (adenoma) and one malignant
tumour (adenocarcinoma). There were no lung tumours at 1 mg/m3 and no effects at 0.2 mg/m3.
Overall, the tumour incidence, both benign and malignant, and the number of animals with the
tumours were not different from controls. The increased incidence of lung tumours is associated
with prolonged respiratory irritation and the concurrent accumulation of yellow material in the
lung, which occurred throughout the study. In the absence of prolonged exposure to high
concentrations leading to chronic irritation and lung damag e, it is highly unlikely that tumour
formation will occur.

SECTION 4 FIRST-AID MEASURES
DescripƟon of first aid measures
Eye Contact
If this product comes in contact with the eyes:
Wash out immediately with fresh running water.
Ensure complete irrigaƟon of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally liŌing the
upper and lower lids.
Seek medical aƩenƟon without delay; if pain persists or recurs seek medical aƩenƟon.
Removal of contact lenses aŌer an eye injury should only be undertaken by skilled personnel.
Skin Contact
If skin or hair contact occurs:
Flush skin and hair with running water (and soap if available).
Seek medical aƩenƟon in event of irritaƟon.
InhalaƟon
If fumes or combusƟon products are inhaled remove from contaminated area.
Lay paƟent down. Keep warm and rested.
Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to iniƟaƟng first aid procedures.
Apply arƟficial respiraƟon if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as
trained. Perform CPR if necessary.
n-pentane
Transport to hospital, or doctor.
IngesƟon
If swallowed do NOT induce vomiƟng.
If vomiƟng occurs, lean paƟent forward or place on leŌ side (head-down posiƟon, if possible) to maintain open airway and prevent
aspiraƟon.
Observe the paƟent carefully.
Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.
Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.
Seek medical advice.
Avoid giving milk or oils.
Avoid giving alcohol.
If spontaneous vomiƟng appears imminent or occurs, hold paƟent's head down, lower than their hips to help avoid possible aspiraƟon of
vomitus.
Most important symptoms and effects, both acute and delayed
See SecƟon 11
IndicaƟon of any immediate medical aƩenƟon and special treatment needed
For acute or short term repeated exposures to petroleum disƟllates or related hydrocarbons:
Primary threat to life, from pure petroleum disƟllate ingesƟon and/or inhalaƟon, is respiratory failure.
PaƟents should be quickly evaluated for signs of respiratory distress (e.g. cyanosis, tachypnoea, intercostal retracƟon, obtundaƟon) and given oxygen. PaƟents with
inadequate Ɵdal volumes or poor arterial blood gases (pO2 50 mm Hg) should be intubated.
Arrhythmias complicate some hydrocarbon ingesƟon and/or inhalaƟon and electrocardiographic evidence of myocardial injury has been reported; intravenous lines and
cardiac monitors should be established in obviously symptomaƟc paƟents. The lungs excrete inhaled solvents, so that hypervenƟlaƟon improves clearance.
A chest x-ray should be taken immediately aŌer stabilisaƟon of breathing and circulaƟon to document aspiraƟon and detect the presence of pneumothorax.
Epinephrine (adrenalin) is not recommended for treatment of bronchospasm because of potenƟal myocardial sensiƟsaƟon to catecholamines. Inhaled cardioselecƟve
bronchodilators (e.g. Alupent, Salbutamol) are the preferred agents, with aminophylline a second choice.
Lavage is indicated in paƟents who require decontaminaƟon; ensure use of cuffed endotracheal tube in adult paƟents. [Ellenhorn and Barceloux: Medical Toxicology]
Any material aspirated during vomiƟng may produce lung injury. Therefore emesis should not be induced mechanically or pharmacologically. Mechanical means should be used if
it is considered necessary to evacuate the stomach contents; these include gastric lavage aŌer endotracheal intubaƟon. If spontaneous vomiƟng has occurred aŌer ingesƟon, the
paƟent should be monitored for difficult breathing, as adverse effects of aspiraƟon into the lungs may be delayed up to 48 hours.

SECTION 7 HANDLING AND STORAGE
PrecauƟons for safe handling
Safe handling
The conducƟvity of this material may make it a staƟc accumulator., A liquid is typically considered nonconducƟve if its conducƟvity is below
100 pS/m and is considered semi-conducƟve if its conducƟvity is below 10 000 pS/m., Whether a liquid is nonconducƟve or semi-conducƟve,
the precauƟons are the same., A number of factors, for example liquid temperature, presence of contaminants, and anƟ-staƟc addiƟves can
greatly influence the conducƟvity of a liquid.
Even with proper grounding and bonding, this material can sƟll accumulate an electrostaƟc charge. If sufficient charge is allowed to
accumulate, electrostaƟc discharge and igniƟon of flammable air-vapour mixtures can occur.
Containers, even those that have been empƟed, may contain explosive vapours.
Do NOT cut, drill, grind, weld or perform similar operaƟons on or near containers.
Contains low boiling substance:
Storage in sealed containers may result in pressure buildup causing violent rupture of containers not rated appropriately.
Check for bulging containers.
Vent periodically
Always release caps or seals slowly to ensure slow dissipaƟon of vapours
ElectrostaƟc discharge may be generated during pumping - this may result in fire.
Ensure electrical conƟnuity by bonding and grounding (earthing) all equipment.
Restrict line velocity during pumping in order to avoid generaƟon of electrostaƟc discharge (<=1 m/sec unƟl fill pipe submerged to twice
its diameter, then <= 7 m/sec).
Avoid splash filling.
Avoid all personal contact, including inhalaƟon.
Wear protecƟve clothing when risk of exposure occurs.
Use in a well-venƟlated area.
Prevent concentraƟon in hollows and sumps.
Other informaƟon
Store in original containers in approved flame-proof area.
No smoking, naked lights, heat or igniƟon sources.
DO NOT store in pits, depressions, basements or areas where vapours may be trapped.
Keep containers securely sealed.
CondiƟons for safe storage, including any incompaƟbiliƟes
Suitable container
Packing as supplied by manufacturer.
PlasƟc containers may only be used if approved for flammable liquid.
Check that containers are clearly labelled and free from leaks.
For low viscosity materials (i) : Drums and jerry cans must be of the non-removable head type. (ii) : Where a can is to be used as an inner
package, the can must have a screwed enclosure.
For materials with a viscosity of at least 2680 cSt. (23 deg. C)
For manufactured product having a viscosity of at least 250 cSt.
Storage incompaƟbility

NOTE: Detector tubes for n-pentane, measuring in excess of 100 ppm, are commercially available.
The TLV-TWA is thought to be protecƟve against narcoƟc effects produced at higher concentraƟons and the development of axonopathies. Although the possibility exists that
chronic exposure to high concentraƟons may produce polyneuropathy, there is no specific data to support the role of pentane in the pathogenesis of central peripheral distal
axonopathy.
Exposure controls
Appropriate engineering
controls
Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls
can be highly effecƟve in protecƟng workers and will typically be independent of worker interacƟons to provide this high level of protecƟon.
The basic types of engineering controls are:
Process controls which involve changing the way a job acƟvity or process is done to reduce the risk.
Enclosure and/or isolaƟon of emission source which keeps a selected hazard "physically" away from the worker and venƟlaƟon that
strategically "adds" and "removes" air in the work environment.
Personal protecƟon
Eye and face protecƟon
Safety glasses with side shields.
Chemical goggles.
Contact lenses may pose a special hazard; soŌ contact lenses may absorb and concentrate irritants. A wriƩen policy document,
describing the wearing of lenses or restricƟons on use, should be created for each workplace or task.
Skin protecƟon See Hand protecƟon below
Hands/feet protecƟon
The selecƟon of suitable gloves does not only depend on the material, but also on further marks of quality which vary from manufacturer to
manufacturer. Where the chemical is a preparaƟon of several substances, the resistance of the glove material can not be calculated in
advance and has therefore to be checked prior to the applicaƟon.
The exact break through Ɵme for substances has to be obtained from the manufacturer of the protecƟve gloves and.has to be observed
when making a final choice.
Personal hygiene is a key element of effecƟve hand care.
Neoprene gloves
Wear chemical protecƟve gloves, e.g. PVC.
Wear safety footwear or safety gumboots, e.g. Rubber
Body protecƟon See Other protecƟon below
Other protecƟon
Overalls.
PVC Apron.
PVC protecƟve suit may be required if exposure severe.
Eyewash unit.
Some plasƟc personal protecƟve equipment (PPE) (e.g. gloves, aprons, overshoes) are not recommended as they may produce staƟc
electricity.
For large scale or conƟnuous use wear Ɵght-weave non-staƟc clothing (no metallic fasteners, cuffs or pockets).
Non sparking safety or conducƟve footwear should be considered. ConducƟve footwear describes a boot or shoe with a sole made from
a conducƟve compound chemically bound to the boƩom components, for permanent control to electrically ground the foot an shall
dissipate staƟc electricity from the body to reduce the possibility of igniƟon of volaƟle compounds.
Recommended material(s)
GLOVE SELECTION INDEX
Glove selecƟon is based on a modified presentaƟon of the:
"Forsberg Clothing Performance Index".

The wearer must be warned to leave the contaminated area immediately on
detecƟng any odours through the respirator. The odour may indicate that the
mask is not funcƟoning properly, that the vapour concentraƟon is too high, or that
the mask is not properly fiƩed. Because of these limitaƟons, only restricted use of
cartridge respirators is considered appropriate.
Cartridge performance is affected by humidity. Cartridges should be changed aŌer

SECTION 11 TOXICOLOGICAL INFORMATION
InformaƟon on toxicological effects
Inhaled
InhalaƟon of vapours may cause drowsiness and dizziness. This may be accompanied by narcosis, reduced alertness, loss of reflexes, lack of
coordinaƟon and verƟgo.
InhalaƟon of vapours or aerosols (mists, fumes), generated by the material during the course of normal handling, may be damaging to the
health of the individual.
Limited evidence or pracƟcal experience suggests that the material may produce irritaƟon of the respiratory system, in a significant number
of individuals, following inhalaƟon. In contrast to most organs, the lung is able to respond to a chemical insult by first removing or
neutralising the irritant and then repairing the damage. The repair process, which iniƟally evolved to protect mammalian lungs from foreign
maƩer and anƟgens, may however, produce further lung damage resulƟng in the impairment of gas exchange, the primary funcƟon of the
lungs. Respiratory tract irritaƟon oŌen results in an inflammatory response involving the recruitment and acƟvaƟon of many cell types,
mainly derived from the vascular system.
Acute effects from inhalaƟon of high concentraƟons of vapour are pulmonary irritaƟon, including coughing, with nausea; central nervous
system depression - characterised by headache and dizziness, increased reacƟon Ɵme, faƟgue and loss of co-ordinaƟon
Central nervous system (CNS) depression may include nonspecific discomfort, symptoms of giddiness, headache, dizziness, nausea,

– Data available to make classificaƟon
anaestheƟc effects, slowed reacƟon Ɵme, slurred speech and may progress to unconsciousness. Serious poisonings may result in respiratory
depression and may be fatal.
Symptoms of pentane inhalaƟon exposure may include, hyperacƟvity, anaesthesia and a persistent taste of gasoline. Light anaesthesia occurs
in mice aŌer 10 minutes exposure to 70000 ppm n-pentane.
InhalaƟon of high vapour concentraƟons may result in coughing, headache, mild depression, incoordinaƟon, blurred vision, confusion, loss
of appeƟte, nausea, vomiƟng, irregular heartbeat and unconsciousness.
ConcentraƟons of 270 to 400 mg/l isopentane may cause narcosis and cardiac sensiƟsaƟon .
Material is highly volaƟle and may quickly form a concentrated atmosphere in confined or unvenƟlated areas. The vapour may displace and
replace air in breathing zone, acƟng as a simple asphyxiant. This may happen with liƩle warning of overexposure.
IngesƟon
Swallowing of the liquid may cause aspiraƟon of vomit into the lungs with the risk of haemorrhaging, pulmonary oedema, progressing to
chemical pneumoniƟs; serious consequences may result.
Signs and symptoms of chemical (aspiraƟon) pneumoniƟs may include coughing, gasping, choking, burning of the mouth, difficult breathing,
and bluish coloured skin (cyanosis).
Accidental ingesƟon of the material may be damaging to the health of the individual.
IngesƟon of pentanes may result in diarrhoea, haemorrhage of the mucous membranes, or when the liquid vapourises in the trachea,
asphyxiaƟon leading to brain damage or death. IngesƟon may also cause nausea, vomiƟng and abdominal swelling. Large doses (1 ml/kg)
may cause central nervous system depression, ventricular fibrillaƟon and kidney, liver and bone marrow damage.
Considered an unlikely route of entry in commercial/industrial environments. The liquid may produce gastrointesƟnal discomfort and may be
harmful if swallowed. IngesƟon may result in nausea, pain and vomiƟng. Vomit entering the lungs by aspiraƟon may cause potenƟally lethal
chemical pneumoniƟs
Skin Contact
The liquid may be miscible with fats or oils and may degrease the skin, producing a skin reacƟon described as non-allergic contact dermaƟƟs.
The material is unlikely to produce an irritant dermaƟƟs as described in EC DirecƟves .
Repeated exposure may cause skin cracking, flaking or drying following normal handling and use.
Symptoms of pentane exposure may include drying, cracking, itching, blistering, redness, pigmentaƟon, swelling, burning and pain.
Because pentane boils just below body temperature, absorpƟon is not expected to be a significant route of entry. Toluene by comparison is
absorbed through the skin at 20 Ɵmes the rate of n-pentane
Open cuts, abraded or irritated skin should not be exposed to this material
Material on the skin evaporates rapidly and may cause Ɵngling, chilling and even temporary numbness
Entry into the blood-stream through, for example, cuts, abrasions, puncture wounds or lesions, may produce systemic injury with harmful
effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.
Eye
Although the liquid is not thought to be an irritant (as classified by EC DirecƟves), direct contact with the eye may produce transient
discomfort characterised by tearing or conjuncƟval redness (as with windburn).
Eye-contact with the liquid pentanes may result in inflammaƟon of the iris and mucous membranes resulƟng in pain and lachrymaƟon. Eye
contact with liquid or very high vapour concentraƟons may result in drying, redness, swelling and pain.
Chronic
Prolonged or repeated skin contact may cause drying with cracking, irritaƟon and possible dermaƟƟs following.
Limited evidence suggests that repeated or long-term occupaƟonal exposure may produce cumulaƟve health effects involving organs or
biochemical systems.
Chronic exposure to pentanes may result in chemical pneumoniƟs, pulmonary oedema or peripheral neuropathy. Prolonged or repeated
inhalaƟon may cause dizziness, weakness, weight loss, anaemia, nervousness, pain in the limbs and peripheral numbness ("pins and
needles")

Toxic to aquaƟc organisms, may cause long-term adverse effects in the aquaƟc environment.
Do NOT allow product to come in contact with surface waters or to interƟdal areas below the mean high water mark. Do not contaminate water when cleaning equipment or
disposing of equipment wash-waters.
Wastes resulƟng from use of the product must be disposed of on site or at approved waste sites.
When spilled this product may act as a typical oil, causing a film, sheen, emulsion or sludge at or beneath the surface of the body of water. The oil film on water surface may
physically affect the aquaƟc organisms, due to the interrupƟon of the
oxygen transfer between the air and the water
Oils of any kind can cause:
drowning of water-fowl due to lack of buoyancy, loss of insulaƟng capacity of feathers, starvaƟon and vulnerability to predators due to lack of mobility
lethal effects on fish by coaƟng gill surfaces, prevenƟng respiraƟon
asphyxiaƟon of benthic life forms when floaƟng masses become engaged with surface debris and seƩle on the boƩom and
adverse aestheƟc effects of fouled shoreline and beaches
In case of accidental releases on the soil, a fine film is formed on the soil, which prevents the plant respiraƟon process and the soil parƟcle saturaƟon. It may cause deep water
infestaƟon.
For isopentane:
Environmental Fate
Terrestrial fate: An esƟmated Koc value of 520, determined from a water solubility of 48 mg/L indicates that isopentane is expected to have low mobility in soil. VolaƟlisaƟon of
isopentane from moist soil surfaces is expected to be an important fate process given an esƟmated Henry's Law constant of 1.4 atm-cu m/mole, derived from its esƟmated vapor
pressure, 689 mm Hg, and water solubility. Isopentane is expected to volaƟlise from dry soil surfaces based upon its vapor pressure. Following a 6.1 day lag period, isopentane
was completely degraded under aerobic condiƟons using an acƟvated sludge over the course of a 20 day incubaƟon period.
For n-pentane;
Koc : 580-1600
Half-life (hr) air : 72-108
Half-life (hr) H2O surface water : 2.5-168
Henry's atm m3 /mol: 1.26
Log BCF : 1.9-2.35
Environmental fate:
Photolysis, hydrolysis and bioconcentraƟon of n-pentane are not expected to be important environmental fate processes. BiodegradaƟon of n-pentane may occur in soil and
water, however volaƟlisaƟon and to some extent adsorpƟon are expected to be far more important environmental fate processes. A Koc range of 580-1600 indicates a low
mobility class in soil for n-pentane. In aquaƟc systems n-pentane may parƟƟon from the water column to organic maƩer contained in sediments and suspended materials.
DO NOT discharge into sewer or waterways.

SECTION 13 DISPOSAL CONSIDERATIONS
Waste treatment methods
Product / Packaging disposal
LegislaƟon addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws operaƟng in
their area. In some areas, certain wastes must be tracked.
A Hierarchy of Controls seems to be common - the user should invesƟgate:
ReducƟon
Reuse
Recycling
Disposal (if all else fails)
This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use.
DO NOT allow wash water from cleaning or process equipment to enter drains.
It may be necessary to collect all wash water for treatment before disposal.
In all cases disposal to sewer may be subject to local laws and regulaƟons and these should be considered first.
Where in doubt contact the responsible authority.
Recycle wherever possible.
Consult manufacturer for recycling opƟons or consult local or regional waste management authority for disposal if no suitable treatment
or disposal facility can be idenƟfied.
Dispose of by: burial in a land-fill specifically licensed to accept chemical and / or pharmaceuƟcal wastes or IncineraƟon in a licensed
apparatus (aŌer admixture with suitable combusƟble material).
Decontaminate empty containers.
