SOURCE INFORMATION
General Description
BMCA Cedar City LLC (BMCA) is the owner and operator of an insulation board and roofing membrane
production plant in Cedar City, Iron County. The facility operates three separate manufacturing lines for
the production of polyisocyanurate (ISO) insulation board, thermoplastic polyolefin (TPO) roofing
membranes, and polyvinyl chloride (PVC) roofing membranes.

The ISO insulation board production line utilizes methylene diphenyl diisocyanate (MDI), polyol, and a
blowing agent (e.g., pentane). The MDI and blended polyol/blowing agent material is transferred onto a
bottom facer material. Upon contact, the materials exothermically react, polymerize, and cross-link to
rapidly form rigid closed-cell foam. The foam board is ultimately transferred to a series of enclosures to
be cut to final dimensions. Emissions generated from the ISO foam board production line are captured
and routed first through a baghouse for particulate control and then to a regenerative thermal oxidizer
(RTO) to control VOCs.

The TPO and PVC roofing membrane production lines utilize a pneumatic conveyance system to convey
the raw materials to feeder bins that meter the raw materials into the extruders. In the extruders, polymers
and additives are blended and heated. The core extrudate passes through a die and is applied directly to a
scrim reinforcement sheet, typically woven polyester material. After application of the core (bottom of the
roofing membrane) onto the scrim, the sheet passes through a series of calendar rolls that press the core
onto the scrim. The sheet then passes to the cap extruder die, where the cap (top of the roofing membrane)
extrudate is applied to the other side of the scrim. Additional calendar rolls are employed to assist with
bonding the cap to the scrim.

Notice Content
NOTICE A Notice of Intent for the following project submitted in accordance with R307-401-1, Utah Administrative Code (UAC), has been
received for consideration by the Director: Company Name: BMCA Cedar City LLC Location: BMCA Cedar City LLC- Insulation Board and
Roofing Membrane Production Plant – 5080 West Highway 56, Cedar City, UT Project Description: BMCA Cedar City LLC (BMCA) is the owner
and operator of an insulation board and roofing membrane production plant in Cedar City, Iron County. The facility operates three separate
manufacturing lines for the production of polyisocyanurate (ISO) insulation board, thermoplastic polyolefin (TPO) roofing membranes, and
polyvinyl chloride (PVC) roofing membranes. The ISO insulation board production line utilizes methylene diphenyl diisocyanate (MDI), polyol,
and a blowing agent (e.g., pentane). The MDI and blended polyol/blowing agent material is transferred onto a bottom facer material. Upon
contact, the materials exothermically react, polymerize, and cross-link to rapidly form rigid closed-cell foam. The foam board is
ultimately transferred to a series of enclosures to be cut to final dimensions. Emissions generated from the ISO foam board production line
are captured and routed first through a baghouse for particulate control and then to a regenerative thermal oxidizer (RTO) to control VOCs.
The TPO and PVC roofing membrane production lines utilize a pneumatic conveyance system to convey the raw materials to feeder bins that
meter the raw materials into the extruders. In the extruders, polymers and additives are blended and heated. The core extrudate passes
through a die and is applied directly to a scrim reinforcement sheet, typically woven polyester material. After application of the core (bottom
of the roofing membrane) onto the scrim, the sheet passes through a series of calendar rolls that press the core onto the scrim. The
sheet then passes to the cap extruder die, where the cap (top of the roofing membrane) extrudate is applied to the other side of the scrim.
Additional calendar rolls are employed to assist with bonding the cap to the scrim. BMCA has requested to install one (1) new fluidized sand
bath for maintenance purposes in the TPO plant and one (1) new off-line CNC custom cut saw (off-line CNC cut saw) for supplementing its
operations in the ISO plant. The new equipment will generate emissions of particulate matter, volatile organic compounds (VOCs), and
hazardous air pollutants (HAPs). The completed engineering evaluation and air quality impact analysis showed the proposed project
meets the requirements of federal air quality regulations and the State air quality rules. The Director intends to issue an Approval Order
pending a 30-day public comment period. The project proposal, estimate of the effect on local air quality and draft Approval Order are
available for public inspection and comment at the Utah Division of Air Quality, 195 North 1950 West, Salt Lake City, UT 84116. Written
comments received by the Division at this same address on or before December 21, 2024, will be considered in making the final decision on
the approval/disapproval of the proposed project. Email comments will also be accepted at [e-mail]. If anyone so requests to the
Director in writing within 15 days of publication of this notice, a hearing will be held in accordance with R307-401-7, UAC. Under Section 19-
1-301.5, a person who wishes to challenge a Permit Order may only raise an issue or argument during an adjudicatory proceeding that was
raised during the public comment period and was supported with sufficient information or documentation to enable the Director to fully
consider the substance and significance of the issue. Pub#10782481 Published November 21, 2024 The Spectrum UPAXLP

Review of BACT for New/Modified Emission Units

1. BACT review regarding New Electrically Heated Fluidized Sand Bath The fluidized sand bath will be used solely for cleaning and maintenance purposes. PM10/PM2.5, and VOC emissions are estimated at approximately 1.2E-05 tons/year and 3.2E-05 tons/year,
respectively. Due to the infrequent and low volume of emissions from the fluidized sand bath, the addition of a collection system or back-end control device is considered cost prohibitive. As such, the BMCA will utilize best design and operating practices as the BACT. Specifically, BMCA will
operate the fluidized sand bath in accordance with the manufacturer's specifications and conduct routine maintenance on the equipment to ensure the optimal performance of the fluidized sand bath. BACT is also limiting visible emissions from the fluidized sand bath to 10% opacity. [Last
updated October 17, 2024]
2. BACT review regarding New ISO Off-line CNC Cut Saw
Emissions from the off-line CNC saw will consist of emissions of approximately 0.15 tpy of PM10/PM2.5, 1.03 tpy of VOCs, and 0.03 tpy of HAPs. Control technologies identified for controlled PM10 and PM2.5 emissions include a wet scrubber and a baghouse. A wet scrubber typically removes particulates from a gas stream by spraying it
with a scrubbing liquid or by forcing it through a pool of liquid to remove particulates and other pollutants. Based on literature research, wet scrubbers generally provide a control efficiency around 80%. During use of a baghouse, particulates are removed from a gas stream by forcing the
exhaust through a series of bags that are typically made of woven or felted fabric. Most baghouses can easily achieve a particulate control efficiency greater than 95%. Baghouses are therefore more effective at capturing fine particulates than wet scrubbers. In addition, wet scrubbers produce a wet sludge requiring disposal and have higher operating costs
and lower removal efficiencies compared to baghouses/fabric filters. Therefore, BACT to control PM10 and PM2.5 from the off-line CNC saw is the use of a baghouse capable of achieving a particulate control efficiency of no less than 95%.
The produced ISO boards are partially comprised of foam bubbles that contain VOCs and HAPs. The VOCs and HAPs are released when the ISO boards are cut with the off-line CNC saw. The non-fugitive emissions are estimated to be 0.77 tpy of VOCs and 0.02 tpy of HAPs. Due to the low volumes and infrequent VOC and HAPs emissions, additional add-on control technologies are considered cost prohibitive. Therefore, BACT to control VOCs and HAPs from the new off-line CNC saw is best design and operation practices.

REVIEWER COMMENTS

1. Comment regarding Source Emission Estimates and DAQ Acceptance: Off-Line Cut Saw: The volume removed per cycle is 0.21 ft3. A solids density of 1.98 lb/ft3 and rate of 3 cycles per hour results in a PM10/PM2.5 rate of 1.89 lb/hour. The saw will operate for 4,680 cycles per hour and emit
1.48 tpy pf PM10/PM2.5.
PM emissions from the saw are controlled with a fabric filter that has a PM10/PM2.5 90% capture efficiency and a PM10/PM2.5 85% control efficiency. The resulting emissions are 0.45 lb/hour and 0.35 tpy of PM10 and PM2.5, each. VOC/HAPs emissions from the off-line CNC cut saw are based on worst-case chemical composition by weight in the raw material and data from raw material safety data sheet (SDS) information. Sand Bath: Emissions are based on 365 lbs of resin removed per year. Emission factors for the polymers present in the resin are based on the papers "Development of Emission Factors for Polypropylene Processing-1999" and "Development of Emission Factors for Polyethylene Processing-1996" from
the Journal of the Air & Waste Management Associate. [Last updated October 2, 2024]
2. Comment regarding Additional Changes to 2015 Approval Order:
According to a Compliance Inspection (see memorandum DAQE-CI14603-22, dated April 5, 2022), the following information was gathered at the time of inspection: - Equipment ID# II.A.6 (one (1) natural gas-fired thermal heater rated at 5.0 MMBtu/hr) in the 2015 AO: This thermal heater is actually two separate heaters rated at a total of 1.875 MMBtu/hr each. The current AO has been updated to reflect this change.
- A single 35,000-gallon pentane tank, located outside on the north end of the building, is in use at the source location. The source indicated this tank has no external emission points and is used as a blowing agent in the process. The process area was observed to be completely enclosed within the building with all emissions being routed through the RTO prior to discharging to the atmosphere. This tank has been added to the AO approved equipment list. Emissions from the tank are expected to be negligible (<0.01 tpy VOCs).
- The source maintains several product tanks inside the building as follows:
-Three 20,000-gallon MDI tanks
-Three 20,000-gallon Polyol tanks
-One 7,500-gallon K-Oct tank
-One 7,500-gallon TCPP tank

Engineer Review N146030003: BMCA Cedar City LLC- Insulation Board and Roofing Membrane Production Plant October 17, 2024 Page 15
The above tanks are all located indoors and do not vent to the atmosphere. The tanks have been added to the AO for informational purposes.
BMCA also indicated in its NOI that the facility no longer uses a chart recorder, as referenced in
Conditions I.B.1.e.1 and I.B.1.e.2 of the 2015 AO. Instead, it uses an electronic data historian to record the applicable operating parameters for the RTO. Therefore, the current AO has been revised to replace "chart recorder" with "electronic data historian." Condition II.B.1.e.1 in the 2015 AO
specifies that "The minimum tolerance of the thermocouple is &plusmn;10.5oF or &plusmn;0.75%.". This equates to a temperature tolerance of between 1489.5oF and 1510.5oF or 1488.75oF and 1511.25oF, respectively. The minimum acceptable temperature is therefore equal to 1488.75oF. The
condition has been updated accordingly. BMCA also indicated that the facility currently uses an activated carbon filter on the MDI tank which is capable of equivalent or better control compared to coalescing filters. The facility also currently uses activated carbon filters on the loading/unloading tanks. These filters provide
equivalent or better control than a vapor recovery system. Therefore, Conditions II.B.1.i and II.B.1.j in the 2015 AO have been updated to allow for these physical changes. [Last updated October 17, 2024]

3. Comment regarding Federal Standard and Title V Applicability: The NSPS and MACT federal standards were reviewed, and none were determined to be applicable
to the Facility. Title V of the 1990 Clean Air Act (Title V) applies to the following:
1. Any major source 2. Any source subject to a standard, limitation, or other requirement under Section 111 of the Act, Standards of Performance for New Stationary Sources; 3. Any source subject to a standard or other requirement under Section 112 of the Act, Hazardous Air Pollutants. 4. Any Title IV affected source. This facility is not a major source and is not a Title IV source. The facility is not subject to 40 CFR 60 (NSPS), 40 CFR 61 (NESHAP), or 40 CFR 63 (MACT) regulations. Therefore, Title V does not
apply to this facility. [Last updated September 30, 2024]

BMCA Cedar City LLC Approval Order Application 1
1 EXECUTIVE SUMMARY
BMCA Cedar City LLC (BMCA), dba GAF Materials Corporation, operates a roofing materials
manufacturing facility located at 5080 West Highway 56 in Cedar City, Utah (Facility). The Facility
operates three separate manufacturing lines for the production of polyisocyanurate (ISO) insulation board,
thermoplastic polyolefin (TPO) roofing membranes, and polyvinyl chloride (PVC) roofing membranes.
The Facility operates under Approval Order DAQE-AN146030002-l5 (Approval Order) issued by the Utah
Department of Environmental Quality (DEQ) on 18 November 2015.

The Facility plans to install one (1) new fluidized sand bath for maintenance purposes in the TPO plant and
one (1) new off-line CNC custom cut saw (off-line CNC saw) for supplementing its operations in the ISO
plant (Project). The new equipment will generate minor emissions of particulates, volatile organic
compounds (VOCs), and federally listed hazardous air pollutants (HAPs). Emission calculations
demonstrate that the new equipment will not cause Facility-wide potential emissions to exceed the Title V
major source threshold of 100 tons per year (tons/year) for any criteria pollutant, 10 tons/year of a single
HAP, or 25 tons/year of aggregate HAP emissions. As a result, this application is being submitted as a
Notice of Intent (NOI) in accordance with Rule 307-401-5 of the Utah Administrative Code (UAC R307-
401-5) to request authorization to construct the new process equipment. The required Utah DEQ application
forms are included in Appendix A. Emission calculations and raw material safety data sheets (SDSs) are
included in Appendices B and C, respectively.

In addition to the Project described above, the Facility is requesting a few minor administrative revisions
to its current Approval Order as summarized in Table 1-1 below.

BMCA Cedar City LLC Approval Order Application 4
3 PROCESS DESCRIPTION
The Facility operates three separate production lines identified in its Approval Order as (1) ISO Foam Line,
(2) TPO Line, and (3) PVC Line. As no changes are occurring to the Facility’s primary production
operations, the process descriptions provided herein contain only a high-level account of the various
operations. Refer to the Facility’s latest Approval Order application for additional process-specific details.
3.1 TPO & PVC ROOFING MEMBRANE PRODUCTION LINES
Raw materials are received via truck and rail and stored in Gaylord boxes, sacks, and silos equipped with
bin vents for collection of pellets that may be displaced by pneumatic air during loading events. A
pneumatic conveyance system is employed to convey the raw materials to feeder bins that meter the raw
materials into the extruders at the appropriate rate. In the extruders, polymers and additives are blended and
heated. The core extrudate passes through a die and is applied directly to a scrim reinforcement sheet,
typically woven polyester material. After application of the core (bottom of the roofing membrane) onto
the scrim, the sheet passes through a series of calender rolls that press the core onto the scrim. The sheet
then passes to the cap extruder die where the cap (top of the roofing membrane) extrudate is applied to the
other side of the scrim. Additional calender rolls are employed to assist with bonding the cap to the scrim.
Emissions generated from the TPO & PVC roofing membrane production lines are captured and routed first
through a baghouse for particulate control and then to a regenerative thermal oxidizer (RTO) to control
VOCs.
Fluidized Sand Bath
The Facility plans to install a fluidized sand bath to remove cured resin from various mechanical parts. The
fluidized sand bath is an electrically heated bath consisting of small, loosely packed, solid aluminum oxide
particles. A flow of hot air is passed upwards through the bath, mobilizing the particles into a fluidized
state. Mechanical parts are then placed within the bath for a specified time allowing the fluidized aluminum
to melt the resin from the metal substrate. As the bath is composed of tiny, inert aluminum oxide particles,
evaporation/volatilization does not occur. Therefore, air emissions are only generated from melting the
resin.
3.2 ISO FOAM BOARD PRODUCTION LINE
The foam board manufacturing process utilizes three (3) primary raw materials: methylene diphenyl
diisocyanate (MDI), polyol, and a blowing agent (e.g., pentane). These liquid raw materials are received
via truck or railcar and are stored onsite in aboveground storage tanks. The MDI and blended
polyol/blowing agent material is pumped through the spray heads at the pour table onto a bottom facer
material in evenly spaced intervals. Upon contact, the materials exothermically react, polymerize, and
cross-link to rapidly form rigid closed cell foam. The blowing agent is trapped within the foam’s closed
cells to form the void spaces. Once the initial reaction occurs, the blowing agent is “locked” into the foam
and cannot be released unless void spaces are destroyed. The foam board is ultimately transferred to a series
of enclosures to be cut to final dimensions. Emissions generated from the ISO foam board production line
are captured and routed first through a baghouse for particulate control and then to an RTO to control VOCs.

BMCA Cedar City LLC Approval Order Application 5
Off-Line CNC saw
The Facility plans to install one off-line CNC saw to enhance its cutting operations. The CNC saw will be
used to cut ISO board into various shapes for certain specialized products. Particulate emissions generated
during operation of the saw will be captured via an exhaust hood and routed to a new baghouse. Minor
quantities of volatile organic compounds (VOCs) will also be produced when cutting the pentane foam
bubbles contained within the ISO board. However, VOC controls will not be used, as VOC emissions are
estimated to be insignificant.

4 EMISSION CALCULATIONS
Emissions from this Project have been estimated as described in this section. Facility-wide potential
emissions are summarized in Table 4-1. Detailed emission calculations are provided in Appendix B.

CO2e 7,725 -- 7,725
Total HAPs 6.66 0.03 6.69

A discussion of the calculation methodologies for the Facility’s new Project equipment is provided in the
following sections.
4.1 FLUIDIZED SAND BATH
Emissions from the fluidized sand bath are only generated via the melting of the plastic polymer and will
comprise trivial quantities of particulates, VOCs, and HAPs. The maximum quantity of polymer to be
removed was estimated based on the following process information:

• The Facility plans to clean a maximum of one part per day (parts/day) which could contain a
maximum of 0.5 pounds (lb) of cured polymer.
• This number was doubled to conservatively account for potential variability in the cleaning
operation (i.e., maximum daily quantity of polymer removed = 1 lb/day).
• A maximum annual quantity of 365 lb/year was then calculated by assuming the fluidized sand
bath operates continuously for 365 days/year.

Using the maximum annual quantity of removed polymer, emissions were estimated assuming the polymer
removal operations could be mathematically modeled as a plastic extrusion operation. Emission factors for
plastic extrusion were obtained from the Journal of the Air & Waste Management Association for
polyethylene and polypropylene and the maximum emission factor between the two polymers was selected
for conservatism. The emission factors were coupled with the estimated maximum quantity of removed
polymer to calculate hourly and annual emissions. Detailed emission calculations are provided in Appendix
B-5.

BMCA Cedar City LLC Approval Order Application 7
4.2 OFF-LINE CNC SAW
Emissions associated with the foam board manufacturing process (L01) include particulates, VOCs, and
HAPs. Exhaust from the new off-line CNC saw will be captured and routed to a baghouse prior to
discharging to the atmosphere. Emissions were estimated by calculating a maximum weight of material to
be removed by the CNC saw and incorporating the appropriate control efficiency1 provided by the new
baghouse. Detailed calculations for particulate emissions are provided in Appendix B-2.

Minor quantities of VOC and HAP emissions will be generated when the ISO board is cut to dimension, as
the cutting operation will liberate gaseous bubbles entrapped within the foam. Emissions were estimated
based on the maximum foam production rate, the maximum content of each raw material in the foam
product, the maximum content of each chemical in the raw material2, and estimated chemical release rates.
A final emission rate for the off-line CNC saw was calculated based on 98.6% of the total VOC emissions
generated from the ISO foam line being emitted from other process sources such as, but not limited to, the
pour table.3 Therefore, approximately 1.4% of total VOC emissions were assumed to be emitted from the
off-line CNC saw. Detailed emission calculations are provided in Appendix B-3. A summary of total
emissions generated from the off-line CNC saw is provided in Appendix B-4.

1 The baghouse will utilize MERV 15 ultra web filters. Estimated control efficiencies for a MERV 15 filter were taken from the USEPA’s website at: https://www.epa.gov/indoor-air-quality-iaq/what-merv-rating
2 Determined from review of the material’s SDS.
3 This percentage was determined from a recent engineering study conducted at GAF’s sister-facility in Statesboro, Georgia.

BMCA Cedar City LLC Approval Order Application 8
5 REGULATORY APPLICABILITY
An air quality regulatory applicability analysis has been conducted for the Facility. The applicability of
federal and state regulations is discussed below.
5.1 PERMITTING PROGRAMS
Title V (Part 70) Operating Permit Program
The Title V (Part 70) Operating Permit Program requires facilities that meet the definition of a major source
to obtain a Title V Operating Permit. According to 40 CFR Part 70.2, a major source is defined as a
stationary source that has the potential to emit 100 tons/year or more of any criteria pollutant,4 10 tons/year
or more of a single HAP, and/or 25 tons/year or more of total combined HAPs. Post-Project potential
emissions from the Facility will remain below these thresholds. Therefore, the Facility is not subject to the
Title V Operating Permit program and will continue to operate as a minor source.
Prevention of Significant Deterioration
The federal Prevention of Significant Deterioration (PSD) program, codified in 40 CFR §52.21, requires
any new major stationary source or major modification at an existing major stationary source to obtain a
major source air quality construction permit before commencing construction operations. The Utah DEQ
has incorporated the federal PSD program by reference at UAC R307-405. The Facility does not fall into
one of the 28 PSD source categories specified at 40 CFR §52.21(b)(1)(i); therefore, the applicable PSD
major source threshold is 250 tons/year of any regulated new source review (NSR) pollutant. As indicated
in Appendix B-1, post-Project potential emissions from the Facility are less than the PSD major source
threshold. Therefore, the PSD program does not apply.
Nonattainment Area New Source Review
The non-attainment new source review (NNSR) program applies to a facility located in a nonattainment
area that emits or has the potential to emit greater than threshold quantities of nonattainment pollutants.
The Utah DEQ has incorporated the federal NNSR provisions at UAC R307-403. The Facility is located in
Iron County, which is listed as either being in attainment or unclassifiable status5 with all National Ambient
Air Quality Standards (NAAQS). Therefore, the provisions of the NNSR program do not apply to the
Facility.
Utah Permitting
This application is being submitted as a NOI, in accordance with UAC R307-401-5, to request a minor
modification to the Facility’s existing Approval Order for the installation of new process equipment.
5.2 NEW SOURCE PERFORMANCE STANDARDS
New Source Performance Standards (NSPS), codified in 40 CFR Part 60, establish pollutant emission limits
and monitoring, reporting, and recordkeeping requirements for various emission sources based on source

4 Does not include PM but includes PM10 and PM2.5.
5 https://www3.epa.gov/airquality/greenbook/ancl.html.

BMCA Cedar City LLC Approval Order Application 9
type and size. The EPA has delegated authority to the Utah DEQ for most NSPS subparts6 which have been
incorporated by reference at UAC R307-210.7 The NSPS applies to new, modified, or reconstructed
sources. NSPS standards are developed for particular industrial source categories. The applicability of a
particular NSPS to a facility can be ascertained based on the industrial source category covered. The NSPS
were reviewed, and none were determined to be applicable to the Project.
5.3 NATIONAL EMISSION STANDARDS FOR HAPS
National Emissions Standards for Hazardous Air Pollutants (NESHAP), codified in 40 CFR Parts 61 and
63, regulate HAP emission from various affected sources. Similar to the NSPS, the Utah DEQ has been
delegated authority for certain NESHAPs.8 Note that the Facility will remain an area source (i.e., not a
major source) of HAPs as defined in 40 CFR §63.2 following completion of the Project as post-Project
potential emissions will remain less than the major source thresholds of 10 tons/year for each individual
HAP and 25 tons/year for aggregate HAP emissions. The NESHAPs were reviewed, and none were
determined to be applicable to the Project.
5.4 UTAH REGULATIONS & EMISSION STANDARDS
Emission Standards: Fugitive Emissions and Fugitive Dust (UAC R307-205)
This Rule applies statewide to all sources of fugitive emissions and fugitive dust, except for agricultural or
horticultural activities specified in 19-2-114(1)-(3), and any source listed in section IX, Part H of the state
implementation plan or located in a nonattainment or maintenance area for particulate matter with an
aerodynamic diameter of 10 microns or less (PM10). Pursuant to UAC R307-205-4, fugitive emissions from
Project sources will not exceed an opacity of 20%. In addition, the Facility will comply with the applicable
fugitive dust provisions of UAC R307-205-5.
Permits: New and Modified Sources (UAC R307-401)
Pursuant to UAC R307-401-3, an approval order is required prior to the installation of any new air pollution
sources at existing permitted facilities. As such, this NOI application has been prepared to request
authorization from the Utah DEQ to install a new fluidized sand bath and off-line CNC saw. Post-Project
Facility-wide potential emissions will not exceed the Title V major source thresholds. Therefore, the
Facility will remain a minor source.

This NOI application has been prepared in accordance with the NOI criteria outlined in UAC R307-401-5.
The required NOI application forms are provided in Appendix A. A technology review has been performed
to establish best available control technology (BACT) from Project sources, as required by UAC R307-
401-5(d). The results of the BACT analysis are summarized in Section 6.

Visibility (UAC R307-406)
The provisions of this Rule describe visibility impact analyses and apply to any new major source or major
modification proposed in either an attainment area or area of nonattainment area. The Facility is not a major
source and therefore this Rule does not apply.
Permits: Emissions Impact Analysis (UAC R307-410)
This rule establishes the procedures and requirements for evaluating the emissions impact of new or
modified sources that require an approval order under UAC R307-401. The purpose of this Rule is to ensure
that the source will not interfere with the attainment or maintenance of any NAAQS. The rule also
establishes the procedures and requirements for evaluating the impact of HAP emissions.

Project emissions of criteria pollutants were compared to the relevant air dispersion modeling thresholds
specified in UAC R307-410-4. The results, summarized in Table 5-1, demonstrate that the increase in
criteria pollutant emissions will not exceed their respective air dispersion modeling thresholds.

PM2.5 - Combined (fugitives + non-fugitives) 0.44 10 No
NOx -- 40 No
SO2 -- 40 No
CO -- 100 No
Lead -- 0.6 No

The Project will result in minor increases of various HAPs. As a result, HAP emissions increases associated
with the Project were used to conduct the HAP Impact Analysis described in UAC R307-410-5. The results
of the analysis, summarized in Table 5-2, demonstrate that emission increases of HAPs will not exceed the
corresponding emission threshold value calculated in accordance with the methodology specified at UAC
R307-410-5(1)(c)(i)(C). Therefore, air dispersion modeling is not required for HAP emissions.

Permits: Ozone Offset Requirements in Davis and Salt Lake Counties (UAC R 307-
420)
The purpose of this Rule is to maintain the offset provisions of the nonattainment area new source review
permitting program in Salt Lake and Davis Counties. As discussed in Section 5.1.3, the Facility is located
in Iron County. Therefore, this Rule does not apply.
Permits: Ozone Offset Requirements in Davis and Salt Lake Counties (UAC R307-421)
The purpose of UAC R307-421 is to require emission reductions from existing sources to offset emission
increases from new or modified sources of PM10 precursors in Salt Lake and Utah Counties. As discussed
in Section 5.1.3, the Facility is located in Iron County. Therefore, this Rule does not apply.

BMCA Cedar City LLC Approval Order Application 12
6 BACT ANALYSIS
Pursuant to UAC R307-401-5(2)(d), a BACT analysis is required for all proposed sources or modifications
to existing sources. BACT is defined at UAC R307-401-2 as:

"Best available control technology" means an emissions limitation (including a visible emissions
standard) based on the maximum degree of reduction for each air pollutant which would be
emitted from any proposed stationary source or modification which the director, on a case-by-
case basis, taking into account energy, environmental, and economic impacts and other costs,
determines is achievable for such source or modification through application of production
processes or available methods, systems, and techniques, including fuel cleaning or treatment
or innovative fuel combustion techniques for control of such pollutant. In no event shall
application of best available control technology result in emissions of any pollutant which would
exceed the emissions allowed by any applicable standard under 40 CFR parts 60 and 61. If the
director determines that technological or economic limitations on the application of
measurement methodology to a particular emissions unit would make the imposition of an
emissions standard infeasible, a design, equipment, work practice, operational standard or
combination thereof, may be prescribed instead to satisfy the requirement for the application of
best available control technology. Such standard shall, to the degree possible, set forth the
emissions reduction achievable by implementation of such design, equipment, work practice or
operation, and shall provide for compliance by means which achieve equivalent results.

A BACT analysis was conducted for the new fluidized sand bath and off-line CNC saw in accordance with
the methodology described in Section 6.1.
6.1 BACT ANALYSIS METHODOLOGY
BACT is evaluated using a “top-down” approach that involves the following five steps.9
Step 1 – Identify Available Control Options
The first step in BACT review is to identify all available control options for the emission unit and pollutant
under evaluation. As this Project only involves the installation of minor emissions emitting equipment,
available control options were identified through a limited review of the United States Environmental
Protection Agency’s (USEPA) RACT/BACT/LAER Clearinghouse database.10

Control options may include back-end control devices, work practices, routine maintenance activities, etc.
The USEPA defines “available control options” as air pollution control technologies or techniques with a
practical potential for application to the emissions unit and the regulated pollutant under evaluation.11 A
control option that has never been used in practice for the emission unit (or similar emission unit) and
pollutant under evaluation is not considered an available control option. Also, a control option that is

10 The database review was limited to entries over the past 10 years.
11 Top-Down Best Available Control Technology Guidance Document, USEPA OAQPS, 15 March 1990 (Draft).

BMCA Cedar City LLC Approval Order Application 13
theoretical, in research and development, only deployed at pilot or test scale, or otherwise not commercially
available is not considered an available control option.

This step in the process may identify a broad array of control options that have been applied to similar
emission sources but may not be applicable to this Project. Per EPA guidance,

While Step 1 is intended to capture a broad array of potential options for pollution control, this
step of the process is not without limits. EPA has recognized that a Step 1 list of options need
not necessarily include inherently lower polluting processes that would fundamentally redefine
the nature of the source proposed by the permit applicant. BACT should generally not be applied
to regulate the applicant’s purpose or objective for the proposed facility.

In assessing whether an option would fundamentally redefine a proposed source, EPA
recommends that permitting authorities apply the analytical framework recently articulated by
the Environmental Appeals Board. Under this framework, a permitting authority should look
first at the administrative record to see how the applicant defined its goal, objectives, purpose,
or basic design for the proposed facility in its application. The underlying record will be an
essential component of a supportable BACT determination that a proposed control technology
redefines the source.

Accordingly, control options that would prevent the Project from fulfilling its intended purpose or
fundamentally redefine the nature of the Project need not be considered in Step 1.
Step 2 – Eliminate Technically Infeasible Options
The second step in the BACT analysis is to evaluate the technical feasibility of control technologies
identified in Step 1. EPA states the following with regard to technical feasibility:

A demonstration of technical infeasibility should be clearly documented and should show, based
on physical, chemical, and engineering principles, that technical difficulties would preclude the
successful use of the control option on the emissions unit under review.11

Identified control options that are demonstrated to be technically infeasible may be eliminated from further
consideration.

Step 3 – Rank Control Options

Identified control technologies deemed technically feasible under Step 2 are ranked in order of overall
control effectiveness for the air pollutant under review. If the most effective control technology identified
in Step 3 is selected as BACT, the analysis is complete. Otherwise, the process proceeds to Step 4.
Step 4 – Evaluate Impacts of Control Options

Under Step 4, remaining control options are evaluated on the basis of energy, environmental, and/or
economic impacts. The energy impact analysis is based on the amount of energy that would be consumed
(e.g., BTU, kWh) to implement the control option. The environmental impact analysis considers emissions

BMCA Cedar City LLC Approval Order Application 14
of air pollutants as well as non-air environmental impacts (water, waste, etc.) associated with the use of the
control option. The economic impact analysis assesses the cost effectiveness of the control option. Control
options with excessive energy, environmental, and/or economic impacts may be eliminated.

Step 5 – Select BACT

The most effective control option remaining following Step 4 is considered BACT for the air pollutant and
emission unit under review.
6.2 BACT ANALYSIS FOR FLUIDIZED SAND BATH (PM/PM10/PM2.5 & VOCS)
The fluidized sand bath will be used on a limited basis solely for cleaning and maintenance purposes and
will generate trivial quantities of regulated air pollutants. Specifically, particulate and VOC emissions are
estimated at approximately 1.2E-05 tons/year and 3.2E-05 tons/year, respectively. Since emissions will be
insignificant, no collection system or back-end control device is necessary as the cost to install an exhaust
collection and control system would far outweigh any benefit realized from controlling such a minor
quantity of emissions. As such, the Facility will utilize good design and operating practices as the BACT.
Specifically, the Facility will operate the fluidized sand bath in accordance with the manufacturer’s
specifications and conduct routine maintenance on the equipment to ensure the optimal performance of the
fluidized sand bath.

For completeness, a review of the RBLC was conducted for the polymer and resin production industry and
no results identified a fluidized sand bath or similar piece of equipment. As a result, the description provided
above serves as sufficient justification for completing the BACT analysis for the fluidized sand bath.12
6.3 BACT ANALYSIS FOR OFF-LINE CNC SAW (PM/PM10/PM2.5)
Emissions from the off-line CNC saw will comprise minor emissions of particulates and VOCs, including
trivial quantities of HAPs. Particulates are captured in the same exhaust system as VOC emissions.
Particulate emissions will be controlled by a new baghouse. No controls will be implemented for VOCs. A
review of the RBLC was conducted for CNC saws and similar sources in the polymer and resin production
industry. However, the search did not produce any results for a process representative of sawing operations.
As a result, a search was conducted for the board product finishing industry as the description for this
category included sanders, saws, and trimmers.
Step 1 – Identify Available Control Options
The database review identified the following technologies for particulate control:

1. Wet Scrubber: A wet scrubber typically removes particulates from a gas stream by spraying it
with a scrubbing liquid or by forcing it through a pool of liquid to remove particulates and other
pollutants. Based on literature research, wet scrubbers generally provide a control efficiency around
80%.

12 A condensed BACT analysis for equipment with very low emissions was communicated as acceptable on a phone call with Christine Bodell of the Utah DEQ on 06 August 2024.

2. Baghouse/Fabric Filter: Particulates are removed from a gas stream by forcing the exhaust
through a series of bags that are typically made of woven or felted fabric. Most baghouses can
easily achieve a particulate control efficiency greater than 95%.

The results of the RBLC database search are provided in Appendix D.
Step 2 – Eliminate Technically Infeasible Options
Both control technologies identified in Step 1 are considered technically feasible.
Step 3 – Rank Control Options
Baghouses are more effective at capturing fine particulates than wet scrubbers. In addition, wet scrubbers
produce a wet sludge requiring disposal and have higher operating costs and lower removal efficiencies
compared to baghouses/fabric filters. Based on the control effectiveness, baghouses rank at the top,
followed by wet scrubbers. The Facility will install a new baghouse to control particulates from the off-line
CNC saw. As such, the Facility has chosen the most effective control option.
Step 4 – Evaluate Impact of Control Options
The most effective control options were selected in Step 3. Therefore, further evaluation is unnecessary.
Step 5 – Select BACT
The BACT selected for this project is a baghouse/fabric filter capable of achieving a particulate control
efficiency of at least 95%.
6.4 BACT ANALYSIS FOR OFF-LINE CNC SAW (VOCS)
Minor emissions of VOCs are generated from the off-line CNC saw when cutting the pentane foam bubbles
contained within the ISO board. As shown in Appendix B-4, VOC emissions from the off-line CNC saw
are estimated at less than 1 ton/year. No back-end controls are planned for VOC emissions from the off-
line CNC saw as it would not be economically feasible to implement controls for such low quantities of
VOCs. The same search described in Section 6.3 was used to identify potential BACT for VOCs from
process saws.
Step 1 – Identify Available Control Options
The search identified good design and operation practices as the only control options for VOC emissions
from sanding and sawing operations. The results of the RBLC database search are provided in Appendix D.
Step 2 – Eliminate Technically Infeasible Options
The use of good design and operation practices is considered technically feasible for the off-line CNC saw.

Step 3 – Rank Control Options

BMCA Cedar City LLC Approval Order Application 16
As only one control option was identified, ranking is unnecessary. The Facility will apply good design and
operation practices when operating the off-line CNC saw.
Step 4 – Evaluate Impact of Control Options
The most effective control options were selected in Step 3. Therefore, further evaluation is unnecessary.
Step 5 – Select BACT
Good design and operation practices is selected as BACT. The Facility will operate the saw in accordance
with the manufacturer’s specifications and will conduct routine maintenance activities to ensure optimal
performance of the CNC saw.

D. Notes
[1] Worst-case composition by weight in raw material. Data from raw material SDS information.
[10] The European Union (EU) Risk Assessment Report for TCPP (2008) quantifies the release rate of TCPP to air from rigid foam manufacturing operations, including due to volatilization from the foam while at elevated
temperatures (curing), at 0.025%.
[11] Based on the comparison of vapor pressures of Catalysts 1, 2, & 3 (10-4 psi to 10-3 psi) and Polyol (10-2 psi) at standard conditions as noted on the SDSs, it seems reasonable to assume that Polyol and the Catalysts have
the same release rates. This is a conservative assumption, given that Polyol has higher vapor pressure than the catalysts.

D.Notes
[1] The fluidized sand bath is electrically heated. The bath consists of small, loosely packed, solid aluminum oxide particles through which an upward
flow of air is passed. In the fluidized state, the aluminum oxide particles become mobile, and the bath displays many of the properties of a liquid.
However, since the bath is composed of tiny, inert aluminum oxide particles, evaporation/volatilization does not occur. Therefore, the only air
emissions produced would be from melting the resin.

4. FIRST AID MEASURES
Description of first aid measures
General advice:
First Aid responders should pay attention to self-protection and use the recommended protective
clothing (chemical resistant gloves, splash protection). If potential for exposure exists refer to Section
8 for specific personal protective equipment.

Inhalation: Move person to fresh air and keep comfortable for breathing. If not breathing, give
artificial respiration; if by mouth to mouth use rescuer protection (pocket mask, etc). If breathing is
difficult, oxygen should be administered by qualified personnel. Call a physician or transport to a
medical facility.

Skin contact: Remove material from skin immediately by washing with soap and plenty of water.
Remove contaminated clothing and shoes while washing. Seek medical attention if irritation or rash
occurs. Wash clothing before reuse. An MDI skin decontamination study demonstrated that cleaning
very soon after exposure is important, and that a polyglycol-based skin cleanser or corn oil may be
more effective than soap and water. Discard items which cannot be decontaminated, including leather
articles such as shoes, belts and watchbands. Suitable emergency safety shower facility should be
available in work area.

Eye contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5
minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay,
preferably from an ophthalmologist. Suitable emergency eye wash facility should be immediately
available.

Ingestion: If swallowed, seek medical attention. Do not induce vomiting unless directed to do so by
medical personnel.

Most important symptoms and effects, both acute and delayed:
Aside from the information found under Description of first aid measures (above) and Indication of
immediate medical attention and special treatment needed (below), any additional important
symptoms and effects are described in Section 11: Toxicology Information.

Indication of any immediate medical attention and special treatment needed
Notes to physician: Maintain adequate ventilation and oxygenation of the patient. May cause
respiratory sensitization or asthma-like symptoms. Bronchodilators, expectorants and antitussives
may be of help. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids.
Respiratory symptoms, including pulmonary edema, may be delayed. Persons receiving significant
exposure should be observed 24-48 hours for signs of respiratory distress. If you are sensitized to
Product name: PAPI™ 580N Polymeric MDI Issue Date: 03/18/2020

Page 4 of 16

diisocyanates, consult your physician regarding working with other respiratory irritants or sensitizers.
Treatment of exposure should be directed at the control of symptoms and the clinical condition of the
patient. Excessive exposure may aggravate preexisting asthma and other respiratory disorders (e.g.
emphysema, bronchitis, reactive airways dysfunction syndrome).

5. FIREFIGHTING MEASURES
Extinguishing media

Suitable extinguishing media: Water fog or fine spray.. Dry chemical fire extinguishers..
Carbon dioxide fire extinguishers.. Foam.. Alcohol resistant foams (ATC type) are preferred.
General purpose synthetic foams (including AFFF) or protein foams may function, but will be
less effective..

Unsuitable extinguishing media: Do not use direct water stream.. May spread fire..

Special hazards arising from the substance or mixture

Hazardous combustion products: During a fire, smoke may contain the original material in
addition to combustion products of varying composition which may be toxic and/or irritating..
Combustion products may include and are not limited to:. Nitrogen oxides.. Isocyanates..
Hydrogen cyanide.. Carbon monoxide.. Carbon dioxide..

Unusual Fire and Explosion Hazards: Product reacts with water. Reaction may produce
heat and/or gases.. This reaction may be violent.. Container may rupture from gas generation
in a fire situation.. Violent steam generation or eruption may occur upon application of direct
water stream to hot liquids.. Dense smoke is produced when product burns..

Advice for firefighters

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry..
Stay upwind. Keep out of low areas where gases (fumes) can accumulate.. Water is not
recommended, but may be applied in large quantities as a fine spray when other extinguishing
agents are not available.. Do not use direct water stream. May spread fire.. Fight fire from
protected location or safe distance. Consider the use of unmanned hose holders or monitor
nozzles.. Immediately withdraw all personnel from the area in case of rising sound from
venting safety device or discoloration of the container.. Move container from fire area if this is
possible without hazard.. Use water spray to cool fire-exposed containers and fire-affected
zone until fire is out.. Contain fire water run-off if possible. Fire water run-off, if not contained,
may cause environmental damage.. Review the "Accidental Release Measures" and the
"Ecological Information" sections of this (M)SDS..

Special protective equipment for firefighters: Wear positive-pressure self-contained
breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet,
coat, trousers, boots, and gloves).. Avoid contact with this material during fire fighting
operations. If contact is likely, change to full chemical resistant fire fighting clothing with self-
contained breathing apparatus. If this is not available, wear full chemical resistant clothing
with self-contained breathing apparatus and fight fire from a remote location.. For protective
equipment in post-fire or non-fire clean-up situations, see Section 8 of the safety data sheet..

OSHA Z-1 C 0.2 mg/m3 0.02 ppm
Further information: (b): The value in mg/m3 is approximate.; ©: Ceiling limit is to be
determined from breathing-zone air samples.

Exposure controls
Engineering controls: Use only with adequate ventilation. Local exhaust ventilation may be
necessary for some operations. Provide general and/or local exhaust ventilation to control airborne
levels below the exposure guidelines. Exhaust systems should be designed to move the air away
from the source of vapor/aerosol generation and people working at this point. The odor and irritancy
of this material are inadequate to warn of excessive exposure.

Individual protection measures
Eye/face protection: Use chemical goggles.
Skin protection
Hand protection: Use gloves chemically resistant to this material. Examples of
preferred glove barrier materials include: Butyl rubber. Polyethylene. Chlorinated
polyethylene. Ethyl vinyl alcohol laminate ("EVAL"). Examples of acceptable glove
barrier materials include: Viton. Neoprene. Polyvinyl chloride ("PVC" or "vinyl").
Nitrile/butadiene rubber ("nitrile" or "NBR"). NOTICE: The selection of a specific glove
for a particular application and duration of use in a workplace should also take into
account all relevant workplace factors such as, but not limited to: Other chemicals
which may be handled, physical requirements (cut/puncture protection, dexterity,
thermal protection), potential body reactions to glove materials, as well as the
instructions/specifications provided by the glove supplier.
Other protection: Use protective clothing chemically resistant to this material.
Selection of specific items such as face shield, boots, apron, or full body suit will
depend on the task.
Respiratory protection: Atmospheric levels should be maintained below the exposure
guideline. When atmospheric levels may exceed the exposure guideline, use an approved air-
purifying respirator equipped with an organic vapor sorbent and a particle filter. For situations
where the atmospheric levels may exceed the level for which an air-purifying respirator is
effective, use a positive-pressure air-supplying respirator (air line or self-contained breathing
apparatus). For emergency response or for situations where the atmospheric level is
unknown, use an approved positive-pressure self-contained breathing apparatus or positive-
pressure air line with auxiliary self-contained air supply.
The following should be effective types of air-purifying respirators: Organic vapor cartridge
with a particulate pre-filter.

10. STABILITY AND REACTIVITY
Reactivity: Diisocyanates react with many materials and the rate of reaction increases with
temperature as well as increased contact; these reactions can become violent. Contact is increased
by stirring or if the other material mixes with the diisocyanate. Diisocyanates are not soluble in water
and sink to the bottom, but react slowly at the interface. The reaction forms carbon dioxide gas and a
layer of solid polyurea. Reaction with water will generate carbon dioxide and heat.

Chemical stability: Stable under recommended storage conditions. See Storage, Section 7.

Possibility of hazardous reactions: Can occur. Exposure to elevated temperatures can cause
product to decompose and generate gas. This can cause pressure build-up and/or rupturing of closed
containers. Polymerization can be catalyzed by: Strong bases. Water.

Conditions to avoid: Exposure to elevated temperatures can cause product to decompose.
Generation of gas during decomposition can cause pressure in closed systems. Pressure build-up
can be rapid. Avoid moisture. Material reacts slowly with water, releasing carbon dioxide which can
cause pressure buildup and rupture of closed containers. Elevated temperatures accelerate this
reaction.

Incompatible materials: Avoid contact with: Acids. Alcohols. Amines. Water. Ammonia. Bases.
Metal compounds. Moist air. Strong oxidizers. Diisocyanates react with many materials and the rate
of reaction increases with temperature as well as increased contact; these reactions can become

Page 8 of 16

violent. Contact is increased by stirring or if the other material mixes with the diisocyanate.
Diisocyanates are not soluble in water and sink to the bottom, but react slowly at the interface. The
reaction forms carbon dioxide gas and a layer of solid polyurea. Reaction with water will generate
carbon dioxide and heat. Avoid contact with metals such as: Aluminum. Zinc. Brass. Tin. Copper.
Galvanized metals. Avoid contact with absorbent materials such as: Moist organic absorbents. Avoid
unintended contact with polyols. The reaction of polyols and isocyanates generate heat.

Hazardous decomposition products: Decomposition products depend upon temperature, air supply
and the presence of other materials.. Gases are released during decomposition..

SECTION 4: First aid measures
Eye Contact: If irritation or redness develops from exposure, flush eyes with clean water. If symptoms persist, seek medical
attention.
Skin Contact: Remove contaminated shoes and clothing and cleanse affected area(s) thoroughly by washing with mild soap and
water or a waterless hand cleaner. If irritation or redness develops and persists, seek medical attention.
Inhalation: First aid is not normally required. If breathing difficulties develop, move victim away from source of exposure and into
fresh air in a position comfortable for breathing. Seek immediate medical attention.
Ingestion: Aspiration hazard: Do not induce vomiting or give anything by mouth because this material can enter the lungs and
cause severe lung damage. If victim is drowsy or unconscious and vomiting, place on the left side with the head down. If possible,
do not leave victim unattended and observe closely for adequacy of breathing. Seek medical attention.
Most important symptoms and effects, both acute and delayed: Effects of overexposure can include slight irritation of the
respiratory tract, nausea, vomiting, and signs of nervous system depression (e.g., headache, drowsiness, dizziness, loss of
coordination, disorientation and fatigue). Continued exposure to high concentrations can result in vomiting, cardiac irregularities
and sudden loss of consciousness. Prolonged or repeated contact may dry skin and cause irritation.
Notes to Physician: Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias in persons exposed to high
concentrations of hydrocarbon solvents (e.g., in enclosed spaces or with deliberate abuse). The use of other drugs with less
arrhythmogenic potential should be considered. If sympathomimetic drugs are administered, observe for the development of
cardiac arrhythmias.
SECTION 5: Firefighting measures
NFPA 704 Hazard Class
Extinguishing Media: Dry chemical, carbon dioxide, or foam is recommended. Water spray is recommended to cool or protect
exposed materials or structures. Carbon dioxide can displace oxygen. Use caution when applying carbon dioxide in confined
spaces. Simultaneous use of foam and water on the same surface is to be avoided as water destroys the foam. Water may be
ineffective for extinguishment, unless used under favorable conditions by experienced fire fighters.
Specific hazards arising from the chemical
Unusual Fire & Explosion Hazards: Extremely flammable. This material can be ignited by heat, sparks, flames, or other
sources of ignition (e.g., static electricity, pilot lights, mechanical/electrical equipment, and electronic devices such as cell
phones, computers, calculators, and pagers which have not been certified as intrinsically safe) Vapors may travel considerable
distances to a source of ignition where they can ignite, flash back, or explode. May create vapor/air explosion hazard indoors,
in confined spaces, outdoors, or in sewers. This product will float and can be reignited on surface water. Vapors are heavier
than air and can accumulate in low areas. If container is not properly cooled, it can rupture in the heat of a fire.
Hazardous Combustion Products: Combustion may yield smoke, carbon monoxide, and other products of incomplete

combustion.
Special protective actions for fire-fighters: For fires beyond the initial stage, emergency responders in the immediate hazard
area should wear protective clothing. When the potential chemical hazard is unknown, in enclosed or confined spaces, a self
contained breathing apparatus should be worn. In addition, wear other appropriate protective equipment as conditions warrant
(see Section 8). Isolate the hazard area and deny entry to unnecessary and unprotected personnel. Stop spill/release if it can be
done safely. Move undamaged containers from immediate hazard area if it can be done safely. Water spray may be useful in
minimizing or dispersing vapors and to protect personnel. Cool equipment exposed to fire with water, if it can be done safely. Avoid
spreading burning liquid with water used for cooling purposes.
See Section 9 for Flammable Properties including Flash Point and Flammable (Explosive) Limits
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures: Extremely flammable. Spillages of liquid product will
create a fire hazard and may form an explosive atmosphere. Keep all sources of ignition and hot metal surfaces away from
spill/release if safe to do so. The use of explosion-proof electrical equipment is recommended. Stay upwind and away from
spill/release. Avoid direct contact with material. For large spillages, notify persons down wind of the spill/release, isolate immediate
hazard area and keep unauthorized personnel out. Wear appropriate protective equipment, including respiratory protection, as
conditions warrant (see Section 8). See Sections 2 and 7 for additional information on hazards and precautionary measures.
Environmental Precautions: Stop and contain spill/release if it can be done safely. Prevent spilled material from entering sewers,
storm drains, other unauthorized drainage systems, and natural waterways. Use foam on spills to minimize vapors Use water
sparingly to minimize environmental contamination and reduce disposal requirements. If spill occurs on water notify appropriate
authorities and advise shipping of any hazard. Spills into or upon navigable waters, the contiguous zone, or adjoining shorelines
that cause a sheen or discoloration on the surface of the water, may require notification of the National Response Center (phone
number 800-424-8802).
Methods and material for containment and cleaning up: Notify relevant authorities in accordance with all applicable
regulations. Immediate cleanup of any spill is recommended. Dike far ahead of spill for later recovery or disposal. Absorb spill with
inert material such as sand or vermiculite, and place in suitable container for disposal. If spilled on water remove with appropriate
methods (e.g. skimming, booms or absorbents). In case of soil contamination, remove contaminated soil for remediation or
disposal, in accordance with local regulations.
Recommended measures are based on the most likely spillage scenarios for this material; however local conditions and
regulations may influence or limit the choice of appropriate actions to be taken.
SECTION 7: Handling and storage
Precautions for safe handling: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
Take precautionary measures against static discharge. Use only non-sparking tools. Wash thoroughly after handling. Use good
personal hygiene practices and wear appropriate personal protective equipment (see section 8). Extremely Flammable. May
vaporize easily at ambient temperatures. The vapor is heavier than air and may create an explosive mixture of vapor and air.
Beware of accumulation in confined spaces and low lying areas. Open container slowly to relieve any pressure. The use of
explosion-proof electrical equipment is recommended and may be required (see appropriate fire codes). Refer to NFPA-70 and/or
API RP 2003 for specific bonding/grounding requirements. Do not enter confined spaces such as tanks or pits without following
proper entry procedures such as ASTM D-4276 and 29CFR 1910.146. Do not wear contaminated clothing or shoes. Keep
contaminated clothing away from sources of ignition such as sparks or open flames.
Static Accumulation Hazard: Electrostatic charge may accumulate and create a hazardous condition when handling this material.
To minimize this hazard, bonding and grounding of tanks, transfer piping, and storage tank level floats are necessary but may not,
by themselves, be sufficient. Review all operations which have the potential of generating and accumulating an electrostatic
charge and/or a flammable atmosphere (including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch
loading, filtering, mixing, agitation, and vacuum truck operations) and use appropriate mitigating procedures. Special care should
be given to ensure that special slow load procedures for "switch loading" are followed to avoid the static ignition hazard that can
exist when higher flash point material (such as fuel oil or diesel) is loaded into tanks previously containing low flash point products
(such as gasoline or naphtha). For more information, refer to OSHA Standard 29 CFR 1910.106, 'Flammable and Combustible
Liquids', National Fire Protection Association (NFPA 77, 'Recommended Practice on Static Electricity', and/or the American
Petroleum Institute (API) Recommended Practice 2003, 'Protection Against Ignitions Arising Out of Static, Lightning, and Stray
Currents'.
Conditions for safe storage: Keep container(s) tightly closed and properly labeled. Use and store this material in cool, dry,
well-ventilated areas away from heat, direct sunlight, hot metal surfaces, and all sources of ignition. Store only in approved
containers. Post area "No Smoking or Open Flame." Keep away from any incompatible material (see Section 10). Protect

container(s) against physical damage. Outdoor or detached storage is preferred. Indoor storage should meet OSHA standards and
appropriate fire codes.
"Empty" containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such
containers to heat, flame, sparks, or other sources of ignition. They may explode and cause injury or death. "Empty" drums should
be completely drained, properly bunged, and promptly shipped to the supplier or a drum reconditioner. All containers should be
disposed of in an environmentally safe manner and in accordance with governmental regulations. Before working on or in tanks
which contain or have contained this material, refer to OSHA regulations, ANSI Z49.1, and other references pertaining to cleaning,
repairing, welding, or other contemplated operations.

Note: State, local or other agencies or advisory groups may have established more stringent limits. Consult an industrial
hygienist or similar professional, or your local agencies, for further information.
Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations below the established
exposure limits, additional engineering controls may be required.
Eye/Face Protection: The use of eye protection that meets or exceeds ANSI Z.87.1 is recommended to protect against potential
eye contact, irritation, or injury. Depending on conditions of use, a face shield may be necessary.
Skin/Hand Protection: The use of gloves impervious to the specific material handled is advised to prevent skin contact. Users
should check with manufacturers to confirm the breakthrough performance of their products. Suggested protective materials: Nitrile
Respiratory Protection: Where there is potential for airborne exposure above the exposure limit a NIOSH certified air purifying
respirator equipped with organic vapor cartridges/canisters may be used.
A respiratory protection program that meets or is equivalent to OSHA 29 CFR 1910.134 and ANSI Z88.2 should be followed
whenever workplace conditions warrant a respirator's use. Air purifying respirators provide limited protection and cannot be used in
atmospheres that exceed the maximum use concentration (as directed by regulation or the manufacturer's instructions), in oxygen
deficient (less than 19.5 percent oxygen) situations, or under conditions that are immediately dangerous to life and health (IDLH).
Suggestions provided in this section for exposure control and specific types of protective equipment are based on readily
available information. Users should consult with the specific manufacturer to confirm the performance of their protective
equipment. Specific situations may require consultation with industrial hygiene, safety, or engineering professionals.

range 1-10 mg/L. n-Pentane will readily evaporate from the surface and would not be expected to have significant adverse effects
in the aquatic environment.
Persistence and Degradability: n-Pentane is expected to be inherently biodegradable. In practice, it is not likely to remain in
solution long enough for biodegradation to be a significant loss process.
Bioaccumulative Potential: The Log Kow value measured for n-pentane is 3.4 and it is expected to have a low potential for
bioaccumulation.
Mobility in Soil: Because of n-pentane's extreme volatility, air is the only environmental compartment in which this hydrocarbon
will be found. In air, n-pentane can readily undergo photodegradation by reaction with hydroxyl radicals. Its chemical half life is
approximately 4 days.
Other adverse effects: None anticipated.
SECTION 13: Disposal considerations
The generator of a waste is always responsible for making proper hazardous waste determinations and needs to consider state
and local requirements in addition to federal regulations. This material, if discarded as produced, would not be a federally
regulated RCRA "listed" hazardous waste. However, it would likely be identified as a federally regulated RCRA hazardous waste
for the following characteristic(s) shown below. See Sections 7 and 8 for information on handling, storage and personal protection
and Section 9 for physical/chemical properties. It is possible that the material as produced contains constituents which are not
required to be listed in the SDS but could affect the hazardous waste determination. Additionally, use which results in chemical or
physical change of this material could subject it to regulation as a hazardous waste.Container contents should be completely used
and containers should be emptied prior to discard. Container residues and rinseates could be considered to be hazardous wastes.
