SOURCE INFORMATION
General Description
Charlotte Pipe and Foundry Company - Plastics Division (Charlotte), operates a pipe manufacturing plant.
The facility produces ABS, CPVC, and PVC pipes. The plant operates compound and resin rail car
unloading stations, compound and resin storage silos, pneumatic material conveyors, extrusion machines,
grinding operations equipment, and ink jet printing lines. Raw material for the pipes arrives in pellet or
granular form and is conveyed from rail cars to storage silos. ABS pellets and CPVC compound are
transferred directly from storage silos to the extrusion machines. PVC resin is transferred to a mixing
station, where minor additives are mixed into the resin. The mixture is then transferred to a second
storage silo, and from that storage silo to the extrusion machines. Waste pipe and/or raw material is
recycled back into usable material through a pulverizing and grinding process. Ink jet printers are used to
print a bar code and specification information on manufactured pipe. The finished pipe is then shipped
off-site.

SOURCE DESCRIPTION

General Description
Charlotte Pipe and Foundry Company - Plastics Division (Charlotte), operates a pipe
manufacturing plant. The facility produces ABS, CPVC, and PVC pipes. The plant operates
compound and resin rail car unloading stations, compound and resin storage silos, pneumatic
material conveyors, extrusion machines, grinding operations equipment, and ink jet printing lines.
Raw material for the pipes arrives in pellet or granular form, and are conveyed from rail cars to
storage silos. ABS pellets and CPVC compound are transferred directly from storage silos to the
extrusion machines. PVC resin is transferred to a mixing station where minor additives are mixed
into the resin. The mixture is then transferred to a second storage silo and from that storage silo
to the extrusion machines. Waste pipe and/or raw material is recycled back into useable material
through a pulverizing and grinding process. Ink jet printers are used to print a bar code and
specification information on manufactured pipe. The finished pipe is then shipped off-site.

Project Proposal
Minor Modification to DAQE-AN141120012-23 to Install Storage Silo

Project Description
Charlotte has requested to add a storage silo for PVC compounds at their production facility. The
silo will store raw materials for PVC production. This modification will result in an increase in
particulate emissions from the storage silo.

EMISSION IMPACT ANALYSIS
All criteria pollutants are below the modeling thresholds contained in R307-410-4. All HAP emissions are
below their respective emission threshold values in R307-410-5. Therefore, no modeling is required for this
source. [Last updated January 1, 2024]

Review of BACT for New/Modified Emission Units

1. BACT review regarding Storage Silo
The new storage silo will increase potential emissions of particulates from PVC compounds stored
and moved through the silo. The silo system operates with a filtration system that regulates air
flow and is necessary for the process due to the potential for high loss of material as it moves
through the silo. This filtration system can be equipped with add-on control devices to control
emissions from the PVC compound material. The easiest option to incorporate into the existing
filtration system are fabric filters. Charlotte evaluated fabric filters to control emissions from the
silo. The proposed filters offer a control efficiency of up to 99.8% and are both technically and
economically feasible to implement. This measure is accepted as BACT for the storage silo.

BACT for control of PM10 and PM2.5 from the storage silo will be the use of fabric filters
guaranteed by the manufacturer to meet a control efficiency of 99.8% and to maintain a 10%
opacity limit. [Last updated February 12, 2024]

REVIEWER COMMENTS

1. Comment regarding Emission Estimates:
Emission estimates for this modification were calculated using the following methods:

Silo Emissions - Emissions for each silo are calculated assuming an hourly throughput of 20,000 lbs
of materials per hour, for 8760 hours per year. An emission factor is used from AP-42 Chapter
11.12, Emission Factors for Concrete Batching, Cement Unloading to Elevated Storage Silo
(pneumatic). The emission factor is for PM10, and PM2.5 emissions are conservatively estimated to be
equal to PM10 emissions. The new silo is estimated to control PM emissions with an efficiency of
99.80% per manufacturer specifications for the fabric filters in the baghouse controlling emissions.
For all other silos, a control efficiency of 99.94% is assumed based on PVC resin particle size
distribution. [Last updated January 2, 2024]

2. Comment regarding NSPS and MACT Review:
40 CFR 60 (NSPS) Subpart IIII applies to "Owners and operators of any stationary CI ICE that are
modified or reconstructed after July 11, 2005 and any person that modifies or reconstructs any
stationary CI ICE after July 11, 2005." The 80 kW emergency diesel generator was constructed and
installed after the applicability date listed in this subpart, and is therefore applicable. The
owner/operator must comply with the emission standards for emergency engines listed in section
60.4205 of this subpart that are applicable to the engine, based on the model year of the engine and
total displacement of the engine cylinders.

40 CFR 63 (MACT) Subpart ZZZZ applies to owners and operators of "stationary RICE at a major
or area source of HAP emissions". The 80 kW emergency engine meets the definition of a stationary
RICE in this subpart, therefore, this subpart applies to the engine. Compliance with this subpart is
met through compliance with NSPS Subpart IIII.
[Last updated January 2, 2024]

3. Comment regarding Title V:
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
61 (NESHAP) regulations. The facility is subject to 40 CFR 60 (NSPS), 40 CFR 63 (MACT)
regulations. 40 CFR 70 (Title V permit) does not apply because NSPS IIII and MACT ZZZZ exempt

Page 13
sources from the obligation to obtain a permit under a Title V permit, if the source is not otherwise
required by law to obtain a permit. There are no other reasons why this source would be required to
obtain a Title V permit; therefore, Title V does not apply to this facility.

August 2023
1.0 SOURCE IDENTIFICATION INFORMATION

Charlotte Pipe and Foundry Company (CPFC) located in Cedar City (Iron County) proposes to
install a new PVC Compound Silo, “Compound Silo #6”.

1.1 COMPANY INFORMATION

Form 2 - Company Information/Notice of Intent (NOI) is provided as Attachment 1.

1.2 AREA DESIGNATION

Iron County is in attainment for all criteria pollutants.

1.3 FEDERAL REQUIREMENT APPLICABILITY

Applicability or non-applicability of the following regulatory programs is addressed in this section:
• Prevention of Significant Deterioration (PSD) permitting;
• Title V of the 1990 Clean Air Act Amendments;
• New Source Performance Standards (NSPS);
• National Emission Standards for Hazardous Air Pollutants (NESHAP);
• Risk Management Plan (RMP);
• Stratospheric Ozone Protection; and
• Utah State Implementation Plan (SIP) regulations.

In addition to providing a summary of applicable requirements, this section of the application also
provides non-applicability determinations for certain regulations. Explanations of non-
applicability are limited to those regulations for which there may be some question of applicability
specific to CPFC. Regulations that are categorically non-applicable are not discussed.

-2- CPFC New Compound Silo #6
August 2023
1.3.1 Prevention of Significant Deterioration (PSD)

PSD standards are applicable to major stationary sources of air pollution. Major stationary sources
are those sources with the potential to emit (PTE) 250 tons per year or more of a regulated New
Source Review (NSR) pollutant. For sources in specific categories (none of which CPFC is
included in), the PTE threshold is 100 tons per year. The PSD regulations are applicable to sources
located in an attainment or unclassifiable area. [40 CFR 51.21]

CPFC facility-wide PTE emissions of regulated NSR pollutants will be less than 250 tons per year
after the proposed installation of the PVC Compound Silo. Therefore, PSD regulations are not
applicable.

1.3.2 Title V of the Clean Air Act Amendments

Any operation meeting the criteria for a major source must apply for an Operating Permit.
Operating Permits are required by Title V of the Clean Air Act Amendments.

Utah Administrative code (UAC) R307-415-3 defines a major source:
“(a) A major source under Section 112 of the Act, Hazardous Air Pollutants…is defined as: … any
stationary source or group of stationary sources located within a contiguous area and under
common control that emits or has the potential to emit, in the aggregate, ten tons per year or more
of any hazardous air pollutant or 25 tons per year or more of any combination of such hazardous
air pollutants.”

“(b) A major stationary source of air pollutants, as defined in Section 302 of the Act,…directly
emits or has the potential to emit, 100 tons per year or more of any air pollutant…”

UAC R307-401-2 defines potential to emit (PTE):
“Potential to emit” means the maximum capacity of a stationary source to emit an air pollutant
under its physical and operational design. Any physical or operational limitation on the capacity
of the source to emit a pollutant, including air pollution control equipment and restrictions on

-3- CPFC New Compound Silo #6
August 2023
hours of operation or on the type or amount of material combusted, stored, or processed, shall be
treated as part of its design if the limitation or the effect it would have on emissions is
enforceable.”

CPFC facility-wide PTE controlled emissions after the proposed addition of Compound Silo #6
will be less than 100 tons per year of criteria pollutants, less than 10 tons per year of any single
HAP and less than 25 tons per year of any combination of HAP. Therefore, Title V regulations
are not applicable.

1.3.3 New Source Performance Standards (NSPS)

Section 111 of the Clean Air Act authorizes the EPA to develop technology based standards which
apply to specific categories of stationary sources. These standards are referred to as New Source
Performance Standards (NSPS) and are found in 40 CFR Part 60.

No NSPS were identified as potentially applicable to the Compound Silo.

1.3.4 National Emission Standards for Hazardous Air Pollutants (NESHAP)

No area source (non-major) NESHAPs were identified as potentially applicable to the Compound
Silo.

1.3.5 Risk Management Plan (RMP)

Processes at CPFC do not exceed threshold quantities of regulated substances in a process, as
determined under §68.115; therefore this rule is not applicable.

1.3.6 Stratospheric Ozone Protection

CPFC does not use ozone depleting substances in facility processes. CPFC will ensure certified
professionals are utilized to service air conditioning units.

August 2023
1.5 SOURCE SIZE DETERMINATION

With this modification the CPFC facility-wide potential to emit will be less than 100 tons per year
for each criteria pollutant, less than 10 tons per year for each single HAP, and less than 25 tons per
year total HAPs. Therefore, CPFC will continue to remain a minor source.

2.0 NOI APPLICATION INFORMATION

Form 4 – Process Data is provided as Attachment 2.

2.1 PROJECT DESCRIPTION

Charlotte Pipe and Foundry Company (CPFC) located in Cedar City (Iron County) proposes to
install a new PVC Compound Silo, “Compound Silo #6”. The proposed silo will be located with
the existing compound silos adjacent to the rail car transfer station, as shown in Figure 1 (Site
Plan).

PVC resin used in the extrusion of PVC pipe is delivered in bulk to CPFC via rail cars. The
material is pneumatically conveyed from the rail cars to storage silos. From the storage silos the
PVC Resin is transferred to mixing stations where minor additives are introduced to the raw
material. The mixed PVC compound is then pneumatically conveyed to a PVC Compound silo.
PVC compound from the storage silos is transferred directly to extrusion machines for pipe
manufacturing.

2.2 FUEL, RAW MATERIAL AND PRODUCTS CONSUMED / PRODUCED

Compound Silo #6 will provide additional storage for PVC compound, which is a mixture of PVC
Resin and a proprietary blend of additives. CPFC is not proposing an increase in PVC resin (raw
material) throughput or storage, or in PVC pipe production.

2.3 DESCRIPTION OF EQUIPMENT AND OPERATING SCHEDULE

Compound Silo #6 will be equipped with a have a rated throughput of 20,000 pounds per hour and
is proposed to be operated 8,760 hours per year. The maximum annual silo throughput rate is
proposed to be 87,600 tons per year.

-7- CPFC New Compound Silo #6
August 2023
The silo will be equipped with a bin vent filtration system as specified below. Drawings and
specifications are provided as Attachments 5, 6, and 7.

Site-specific data from the CPFC facility located in Monroe, NC has indicated the following
particle size distribution for PVC Compound:

PVC Compound Particle Size Distribution
Size

Weight %

Cumulative
%
0-1 0 0
1-10 0 0
10-25 1 1
25-50 1 2
50-100 98 100
>100 0 100

Manufacturer data provided for the filter (Attachment 7) indicates that particle removal efficiency
for particles greater than 8.50 µm is 99.8%. Emission calculations are provided as Attachment 4.

2.4 CHANGES TO PROCESS RATE AND PRODUCTION RATES

The proposed PVC Compound will allow additional storage of the same quantities of PVC
Compound currently mixed at the facility. There are no proposed changes to piping throughput or
production rate.

2.5 BEST AVAILABLE CONTROL TECHNOLOGY (BACT) ANALYSIS

The proposed silo will be equipped with a filtration system that regulates air flow and prevents
loss of material (PVC compound) from the silos during material transfer to and from the silo. It is
not feasible to operate the silos without this filtration system due to extensive loss of raw material.
The filtration system has a minimum PVC compound (particulate) control efficiency of 99.8%.
Controlled particulate emissions are calculated to be 4.12E-02 tons per year. Back calculating, a
particulate control device added in series would require an annualized cost of less than $610,

-8- CPFC New Compound Silo #6
August 2023
assuming $15,000 per ton PM controlled is economically feasible ($15,000 per ton PM x 4.12E-
02 tons PM).

A review of Engineer Reviews associated with recent issued Approval Orders (AO) was conducted
to identify recent BACT determinations for the control of particulate from silos:

2 Emission factor based on AP-42 Chapter 11.12, Emission Factors for Concrete Batching, Cement Unloading to Elevated Storage Silo (pneumatic).
3 The Resin Silo and Compound Silos will utilize fabric filters to control particulate matter emissions.
Example Calculations:
1. For Uncontrolled Potential Emissions:
Potential Emissions (lb/hr) = Potential Throughput (ton/yr) x [Emission Factor (lb/ton) / Potential Hours of Operation (hr/yr)]
Potential Emissions (ton/yr) = Potential Throughput (ton/yr) x [Emission Factor (lb/ton) / 2000 (lb/ton)]
2. For Controlled Potential Emissions:
Potential Emissions (lb/hr) = Potential Throughput (ton/yr) x [Emission Factor (lb/ton) / Potential Hours of Operation (hr/yr)] x (1-Control Efficiency)
Potential Emissions (ton/yr) = Potential Throughput (ton/yr) x [Emission Factor (lb/ton) / 2000 (lb/ton)] x (1-Control Efficiency)
4 Compound Silo #6 based on manufacturers data for particle sizes up to 8.50 µm. Manufacturer efficiency data for all other silos is based on PVC resin particle size distribution, 100% capture of
particle sizes greater than 74 µm and 98.91% capture of particle sizes less than 74 µm. PVC resin is the smallest particle size processed at the facility.
