TITLE V OPERATING PERMIT RENEWAL APPLICATION INTRODUCTION
The Chemours Company—Fayetteville,North Carolina
1. INTRODUCTION
The Chemours Corporation (Chemours) owns and operates a chemical manufacturing facility located at
22828 NC Highway 87 West in Fayetteville, Bladen County, North Carolina(Chemours Company—
Fayetteville Works). The facility currently operates under Title V Operating Permit Number 03735T48
issued by North Carolina Department of Environmental Quality(DEQ), Division of Air Quality (DAQ) on 13
May 2020 and effective on 12 July 2020.
Title V Operating Permit Number 03735T48 expires on 31 March 2021. As provided in Title V Permit
Condition 3.K and 15A North Carolina Administrative Code (NCAC) 02Q .0513, the permittee must submit
a complete Title V renewal application at least six months prior to the date of permit expiration. This
application is intended to satisfy all the requirements of Title V of the 1990 Clean Air Act(CAA)as
encoded in 40 Code of Federal Regulations (CFR) Part 70 and in 15A NCAC 02Q .0500, "Title V
Procedures."
Section 503(d) of the CAA and Title V Permit Condition 3.K provides that, once a timely and complete
application for an operating permit has been filed, the applicant is shielded from enforcement action for
operating without a permit until the permit has been issued or other action has been taken on the

TITLE V OPERATING PERMIT RENEWAL APPLICATION PROCESS OVERVIEW
The Chemours Company—Fayetteville,North Carolina
2. PROCESS OVERVIEW
Chemours Company—Fayetteville Works manufactures chemicals, plastic resins, plastic sheeting and
plastic film at its facility located at 22828 NC Highway 87 West, Fayetteville, Bladen County, North
Carolina (the facility). A site map detailing the location of the site with property boundaries and fencelines
is included in Figure 2-1. The facility is a major source of criteria pollutants under the Part 70 (Title V)
Operating Permit Program and a major source of Hazardous Air Pollutants (HAP).
Specific materials produced at the Fayetteville facility are:
* ChemoursT""Nafion®Membrane (plastic film) used in the chloroalkali industry and in electrochemical
fuel cells.
ChemoursTm Nafion(D Polymer Dispersions used in the fabrication of thin films and coating
formulations for fuel cells membranes, catalyst coatings, sensors, and a variety of electrochemical
applications.
HFPO monomer and Vinyl Ether monomers used to manufacture various fluorochemical products
such as ChemoursTm Teflon@.
t, Fluorocarbon intermediates for Nafion@ membranes and other fluorocarbon products, and
15 Fluoropolymer Processing Aids (PPA) used in the manufacturing of fluoropolymers and fluorinated
telomers.
Production of these materials occurs in several manufacturing or processing areas throughout the plant
site, including Hexafluoropropylene Oxide (HFPO) Process, Vinyl Ethers North Process, Vinyl Ethers
South Process, RSU Process, MMF Process, IXM Resins Process, Semiworks Polymerization
Operations, E-2 Process, TFE/CO2 Separation Process, and Polymer Processing Aid (PPA) Process.
In addition to the manufacturing operations, Chemours operates two natural gas-fired boilers and a
wastewater treatment plant(WWTP)for the treatment of process and sanitary wastewaters from
Chemours, Kuraray, and DuPont(both Kuraray and DuPont are also located on the site). However, no
wastewater is discharged currently from the Chemours facility to the WWTP, except reject water from
making filtered, deionized/degassed water at the power plant. At this time, all process wastewater
generated from the Chemours Company—Fayetteville Works manufacturing facility is collected and
shipped off-site for disposal.
Chemours also operates several additional ancillary activities such as research laboratories, paint shops,
abrasive blasting operations, and emergency generators and fire water pumps.
A list of permitted emission sources are included in Table 2-1 and a list of insignificant activities are
included in Table 2-2. While Section 3 details proposed changes to the Title V Permit, any emissions
source descriptions that vary from the existing Title V Permit are also noted in bold, italicized font in
Tables 2-1 and 2-2.
Since the last Title V Permit renewal, Chemours has added several additional air emission control
devices, primarily for the capture and control of GenX Compounds',while additional VOC reductions are
also realized. The additional air emission control devices include a Thermal Oxidizer and 4-Stage
Scrubber System (CD Nos. NCD-Q1 and NCD-Q2)for the control of process emissions from several
process areas. Figure 2-2 details the sources controlled by the Thermal Oxidizer and 4-Stage Scrubber
' "GenX Compounds"means HFPO Dimer Acid,also known as C3 Dimer Acid(CAS No. 13252-13-6);HFPO Dimer Acid Fluoride,
also known as C3 Dimer Acid Fluoride(CAS No.2062-98-8);and HFPO Dimer Acid Ammonium Salt,also known as C3 Dimer Acid
Ammonium Salt(CAS No.62037-80-3).

3.2 Proposed Permit Changes
As previous discussed, the Chemours Company— Fayetteville Works facility currently operates under
Title V Permit No. 03735T48, which became effective on 12 July 2020. Chemours has conducted a
thorough review of the current Title V Permit and developed a list of proposed changes to the permit
which is detailed in Table 3-2. The majority of the proposed changes are related to the removal of permit
conditions that are no longer applicable, such as:
■ Case-by-Case MACT requirements for the boilers. The boiler are now subject to the requirements of
the federal Boiler MACT(40 CFR 63, Subpart DDDDD); therefore, the Case-by-Case MACT
requirements are no longer applicable.
* Primary Operating Scenarios(POS). Chemours is currently operating under the Alternative
Operating Scenario (AOS), which includes operation of the Thermal Oxidizer and 4-Stage Scrubber
System; therefore, reference to the POS can now be removed from the permit.
■ Completed Compliance Requirements. There are several permit conditions that contain initial
compliance requirements that have been satisfied. To avoid confusion, Chemours is requesting
removal of those requirements from the permit.
Additional changes such as clarification to the carbon bed testing requirements, updates to Toxic Air
Pollutant reporting requirements, and additional minor changes throughout for clarification purposes are
also detailed in the list of proposed permit changes in Table 3-2. A redlined version of Title V Permit No.
03735T48 is also included in Appendix B.
Chemours is also requesting the addition of a Diesel-Fired Emergency Generator for the Remediation
Treatment System, with a rating of 540 horsepower(ID No. I-RICE-05). The emergency generator
qualifies as an insignificant activity under 15A NCAC 02Q .0503(8) since potential emissions of criterial
pollutants are less than 5 tons per year and potential emissions of HAPs are less than 1,000 pounds per
year. Potential emission calculations for the diesel-fired emergency engine are included in Appendix D.

TITLE V OPERATING PERMIT RENEWAL APPLICATION AIR REGULATORY APPLICABILITY ANALYSIS
The Chemours Company—Fayetteville,North Carolina
5. AIR REGULATORY APPLICABILITY ANALYSIS
The applicability determinations made for potentially applicable federal and state air quality regulations
are described in this section for the sources located at the Chemours—Fayetteville Works facility. Federal
regulations are reviewed first, followed by North Carolina regulations. A summary detailing applicability of
each regulation is provided throughout this section.
5.1 Federal Regulations
5.1.1 Permitting Programs
5.1.1.1 Prevention of Significant Deterioration (PSD) of Air Quality, 40 CFR Part 52
The federal PSD program, codified in 40 CFR Part 52.21, requires any new major stationary source of air
pollutants to obtain a major source air construction permit before commencing construction. North
Carolina has incorporated the federal PSD program in 15A NCAC 2Q .0300. The PSD program applies to
a facility if potential emissions exceed applicable major source thresholds. The facility is considered a
chemical process plant,which is one of the 28 listed PSD source categories specified in §52.21(b)(1)(i)(a)
with a 100-tpy PSD major source threshold for regulated New Source Review(NSR) pollutants. Since the
existing facility is a major source with respect to the PSD program, modifications at the facility must
undergo major source review if the proposed project will increase emissions of one of the PSD regulated
pollutants in excess of the applicable pollutant Significant Emission Rate (SER)threshold. The current
permit has numerous PSD avoidance conditions which will remain in the Title V permit.
Chemours opted to take a PSD avoidance limit specified in Permit Condition 2.1 (B)(9) by using projected
emissions for the IXM Membrane Process (ID No. NS-1).As such, Permit Condition 2.1 (13)(9)(b)(ii)
requires that Chemours submit a report 60 days after the end of each calendar year for the actual VOC
emissions from IXM Membrane Coating Process (ID No. NS-1). The report must contains the items listed
in 40 CFR 51.166(r)(6)(v)(a), as follows:
a The name, address and telephone number of the major stationary source;
The annual calculated VOC emissions; and
* Any other information that Chemours wishes to include in the report.
5.1.1.2 Nonattainment Area New Source Review (NNSR)
NNSR is applicable to construction of a new major stationary source or a project that is a major
modification at an existing major stationary source in an area designated as nonattainment for the
National Ambient Air Quality Standards (NAAQS). The facility is located in Bladen County which is
classified as an attainment or unclassifiable county for NSR pollutants. Thus, the facility is not subject to
NNSR.
5.1.1.3 Title V Operating Permit Programs, 40 CFR Part 70
A Title V(Part 70) operating permit is required for facilities that meet the definition of a major source
according to 40 CFR Part 70.2.A facility with criteria pollutant emissions greater than 100 tpy, 10 tpy of a
single HAP, or 25 tpy of a combination of HAPs is considered a major source under the Title V permitting
program. The facility is considered a major source with respect to the Title V permitting program and
operates under the current Permit 03735T48. The permit requires that a Title V renewal application be
submitted at least six months before the date of permit expiration. This application satisfies the
requirements for submittal of a complete renewal application.

5.1.2 New Source Performance Standards, 40 CFR Part 60
New Source Performance Standards (NSPS), codified in Title 40 CFR Part 60, establish pollutant
emission limits and monitoring, reporting, and recordkeeping requirements for various emission sources
based on source type and size. NSPS applies to new, modified, or reconstructed sources as defined by
the particular standard. North Carolina has incorporated the federal NSPS in 15A NCAC 02D .0524.
5.1.2.1 40 CFR Part 60 Subpart A: General Provisions
40 CFR 60 Subpart A conditions are referenced by specific NSPS subparts and as such as mentioned
throughout the permit. Chemours will continue to comply with these requirements as applicable.
5. 1.2.2 40 CFR Part 60 Subpart Dc: Standards of Performance for Small Industrial-
Commercial-Institutional Steam Generating Units
NSPS Subpart Dc applies to the PS-C boiler which has not yet be installed at the facility. Table 5-1
provides a reference to the permit conditions and applicable NSPS Subpart Dc requirements to the PS-C
boiler.
5. 1.2.3 40 CFR Part 60 Subpart Ill/. Standards of Performance for Stationary
Compression Ignition Internal Combustion Engines
Diesel-fired emergency engines (ID Nos. I-RICE-03, I-RICE-04 and I-RICE-05) are subject to the
requirements of NSPS Subpart[Ill. Since these units are listed as insignificant activities, the permit does
not identify specific requirements. NSPS Subpart III[ includes requirements, such as emission standards,
work practices, and recordkeeping for each emission source, as applicable.

5.1.3 National Emission Standards for Hazardous Air Pollutants, 40 CFR Part 61
National Emission Standards for Hazardous Air Pollutants (NESHAP)are generally applicable to sources
of specified HAPs. The NESHAP regulations in 40 CFR 61 are on a pollutant-specific basis. None of the
NESHAP regulations in 40 CFR 61 apply to the Chemours facility.
5.1.4 National Emission Standards for Hazardous Air Pollutants, 40 CFR Part 63
The NESHAP regulations in 40 CFR 63 are established based on Maximum Achievable Control
Technology(MACT)determinations for particular source types. The facility is a major source of HAP
emissions as defined in 40 CFR 63.2. Several emission sources at the facility are subject to 40 CFR 63
MACT requirements.
5.1.4.1 40 CFR 63 Subpart A. General Provisions
40 CFR 63 Subpart A conditions are referenced from specific subparts and are mentioned throughout the
permit. Chemours will continue to comply with these requirements as applicable.
5.1.4.2 40 CFR Part 63 Subpart FFFF: National Emission Standards for Miscellaneous
Organic Chemical Manufacturing
The HFPO, Vinyl Ethers North,Vinyl Ethers South, and IXM Resins processes (ID Nos. NS-A, NS-B, NS-
B-2 NS-C, NS-C-2, NS-G-1 and NS-G2)are subject to the requirements of 40 CFR 63, Subpart FFFF,
"National Emission Standards for Hazardous Air Pollutants: Miscellaneous Organic Chemical
Manufacturing"(also referred to as the Miscellaneous Organic NESHAP, or MON). The MON includes
emission limitations, work practice standards, continuous compliance requirements, recordkeeping, and
reporting requirements for various affected sources. The compliance status of the facility was included
with the Notification of Compliance Status. Permit Condition 2.1 (13)(10) details the site specific MON
requirements.
The facility does not operate any Group 1 process vents, Group 1 storage tanks, or transfer racks or
loading arms. The facility has Group 2 continuous process vents, one Group 2 wastewater stream, and
two heat exchange systems requiring monitoring. There are process streams in all four of the process
units that are subject to the equipment leak provisions, or MON LDAR requirements. Chemours has
elected to follow 40 CFR Subpart UU for LDAR compliance.
Table 5-2 provides an overview of the requirements of Subpart FFFF.
5.1.4.3 40 CFR Part 63 Subpart ZZZZ: National Emission Standards for Hazardous Air
Pollutants for Stationary Reciprocating Internal Combustion Engines
40 CFR Subpart ZZZZ applies to each of the five emergency engines located at the facility(ID Nos. I-
RICE-01, 02, 03, 04, and 05). Since these emissions sources are listed as insignificant activities, the
specific requirements of Subpart ZZZZ are not included in the permit. Table 5-2 provides a summary of
the requirements for Subpart ZZZZ.
For emergency engines that are also subject to the requirements of 40 CFR 60 Subpart III] and have a
site rating of less than 500 brake hp, the emission units comply with the requirements of this subpart by
meeting the requirements in 40 CFR 60 Subpart IIII in accordance with 40 CFR 63.6590(c)(6). In
accordance with 40 CFR 63.6590(b)(1)(i), a new or reconstructed emergency RICE with a rating greater

than 500 brake hp located at a major source of HAPs (i.e., I-RICE-05)does not have to meet the
requirements of NSPS Subpart ZZZZ, with the exception of the initial notification requirements.
5.1.4.4 40 CFR Part 63 Subpart DDDDD - National Emission Standards for Hazardous
Air Pollutants for Major Sources. Industrial, Commercial, and Institutional Boilers
and Process Heaters
40 CFR Part 63 Subpart DDDDD applies to the two existing boilers (ID Nos. PS-A and PS-13) and will
apply to the new boiler(ID Nos. PS-C) upon installation. This subpart will not apply to the temporary
boiler(ID No. PS-TEMP) if installed as long as the boiler does not remain on-site for more than 12
consecutive months. Table 5-2 provides a summary of the requirements of Subpart DDDDD.
In 2011, the State of North Carolina implemented a Case-by-Case MACT under the CAA Section 1120),
since Subpart DDDDD was not implemented in a timely manner by the US EPA. These conditions were
added to the permit in 12 December 2010 (Permit No. 03735T36). The requirements of Subpart DDDDD
now replace those conditions and Chemours is requesting the Case-by-Case MACT conditions be
removed from the permit.

5.1.5 Compliance Assurance Monitoring (CAM), 40 CFR Part 64
Under 40 CFR Part 64, Compliance Assurance Monitoring (CAM), facilities are required to prepare and
submit monitoring plans for certain emission units with certain Title V permit applications. Specifically
CAM applies to any unit that meets all three of the following criteria:
* be subject to an emission limitation or standard,
* use a control device to achieve compliance, and
• have pre-control emissions that exceed or are equivalent to the major source threshold.
Uncontrolled particulate matter emissions from the lime slaker(ID No. NS-R2) does not exceed 100 tpy;
therefore, a CAM plan is not required for the lime slaker system.
Uncontrolled particulate matter emissions from the lime silo (ID No. NS-R1) could exceed 100 tpy, is
subject to an emission standard in 15A NCAC 02D .0515, and uses a control device to achieve
compliance with the standard. As such, a CAM plan is required for the lime silo.
CAM plans compliant with the requirements of 40 CFR Part 64 must accomplish the following:
■ Describe the indicators to be monitored;
■ Describe the ranges or the process to set indicator ranges or conditions;
■ Describe the performance criteria for the monitoring, including
- Specifications for obtaining representative data,
- Verification procedures to confirm the operational status of the monitoring device,
- Quality assurance and control procedures, and
- Monitoring frequency and data averaging period;
■ Provide a justification for the use of parameters, ranges, and monitoring approach; and
r Provide emissions test data, if necessary
The monitoring approach, which addresses each of the aforementioned plan requirements, for the source
(i.e., lime silo)and associated control device (i.e., pulse jet baghouse)that is subject to CAM is
summarized in Appendix C.
5.1.6 Accidental Release Prevention Requirements: Risk Management

NSPS requirements and applicability are addressed in the federal regulatory applicability discussion in
Section 5.1.2.
5.2.7 15A NCAC 02D .0530— Prevention of Significant Deterioration
As discussed in section 5.1.1, the current facility is a major source with respect to the PSD regulations.As
such, an increase in emissions associated with any modification at the facility must be assessed against
the appropriate SER thresholds.
5.2.7.1 15A NCAC 02D .0530(u) - Use of Projected Actual Emissions to Avoid
Applicability of Requirements of PSD

permanent location than is necessary to allow the surface to be blasted.
For abrasive blasting operation conducted outside a building, Chemours will use appropriate
measures to ensure that the fugitive dust emissions created by the abrasive blasting operation
do not migrate beyond the property boundaries in which the abrasive blasting operation is being
conducted.
5.2.9 15A NCAC 02D .1100- Toxic Air Pollutant Emission Limitation and
Requirements and 15A NCAC 02Q .0711 - Toxic Air Pollutant Procedures
The Toxic Air Pollutant Procedures require a permit for any facility with emissions of an Air Toxic Pollutant
listed in 15A NCAC 02D .1104 in excess of the applicable Toxic Pollutant Emission Rates (TPER)
Requiring a Permit presented in 15A NCAC 02Q. 0711. The current permit for the Chemours facility
contains facility-wide emission limits for each of the applicable pollutants emitted at the facility in Section
2.2(B)(1) and 2.2(B)(2).
These emission limits are based on air toxics modeling conducted in 1995 which developed a 'worst-
case' unit impact and backed into facility-wide allowable emission rates. Conditions Section 2.2 (13)(1)(c)
and 2.2 (13)(2)(e) requires Chemours to submit quarterly air toxics reports. Since these quarterly reports
have consistently shown over the past several years that Chemours does not exceed the air toxic limits in
the report and that the installation of the thermal oxidizer and scrubber system will further reduce air toxic
emissions, Chemours is requesting to reduce the reporting frequency to submittal on an annual basis.
In addition Condition 2.1 (C)(1) requires that PPA(ID No.AS-A) be controlled by a wet scrubber(ID No.
ACD-Al)to ensure compliance with this rule. To demonstrate proper performance of the scrubber, the
liquid flow rate should be a minimum of 30 gallons per minute and the differential pressure across the
packed bed section of the scrubber should be a maximum of 12 inches of water. Chemours is required to
maintain records of the inspections on the scrubber. Reporting is not required to demonstrate compliance
with Condition 2.1 (C)(1).
5.2.10 15A NCAC 02D .1111 — Maximum Achievable Control Technology
MACT requirements and applicability are addressed in the federal regulatory applicability discussion in
Section 5.1.4.
5.2.11 15A NCAC 02D .1806— Control and Prohibition of Odorous Emissions
In accordance with 15A NCAC 02D. 1806 and Condition 2.2 (13)(5) requires that a facility not operate
without implementing management practices or installing and operating odor control equipment sufficient
to prevent odorous emissions from the facility from causing or contributing to objectionable odors beyond
the facility's boundary.
Permit Condition 2.1 (D)(1)(a)further specifies that the wastewater treatment sludge dryers (ID Nos.
WTS-B and WTS-C) shall be controlled by a caustic injection scrubber(ID No. WTCD-1). Chemours is
required to perform periodic inspection and maintenance as recommended by the scrubber manufacturer.
Condition Section 2.1(D)(1)(d) requires and inspection and maintenance logbook be kept for the
scrubber. Reporting is not required to demonstrate compliance with this rule.
5.2.12 15A NCAC 02Q .0317— Avoidance Conditions
This rule allows a facility to obtain avoidance conditions from specific permitting requirements. Chemours
has taken conditions to avoid PSD requirements for multiple sources and pollutants as detailed in the
current permit. Conditions 2.1 (A)(5), 2.1 (13)(5), 2.1 (13)(6), 2.1 (13)(7), 2.1 (13)(8), 2.1 (E)(4), and 2.2

used,then this section need not be completed ONLY for the CEMS,COMS,or PEMS,EXCEPT that the Special Criteria Information of 40 CFR 64.3(d)must be
provided. Special Criteria Information may be provided on a separate sheet.
b Describe all indicators to be monitored which satisfy 40 CFR 64.3(a). Indicators of emission control performance for the control device and associated capture
system may include measured or predicted emissions(including visible emissions or opacity),process and control device operating parameters that affect
control device(and capture system)efficiency or emission rates,or recorded findings of inspection and maintenance activities.
Indicator ranges may be based on a single maximum or minimum value or at multiple levels that are relevant to distinctly different operating conditions,
expressed as a function of process variables,expressed as maintaining the applicable indicator in a particular operational status or designated condition,or
established as interdependent between more than one indicator. In addition,unless specifically stated otherwise by an applicable requirement,the owner or
operator shall monitor the indicators to detect any bypass of the control device(or capture system)to the atmosphere.
d The QIP threshold is based on the number of excursions identified in a reporting period. (Example: if the historical monitoring data for a facility indicates that
the indicator range was exceeded 10 times in a 6-month period,the threshold could be established at no more than 10 excursions outside the indicator range
during a 6-month reporting period.) The threshold levels also could be established based on the duration of excursions as a percentage of operating time.
e At a minimum,the owner of a large PSEU must collect four or more data values equally spaced over each hour and average the values. All other PSEUs must
collect data at least once per 24-hour period or possibly more to provide reasonable assurance of compliance over the anticipated range of operating
conditions.

needed,attach additional sheets and label with the appropriate PSEU designation,pollutant,and indicator Nos.
PSEU DESIGNATION POLLUTANT
NS-R1 Particulate Matter
9. INDICATORS AND THE MONITORING APPROACH: Provide the rationale and justification for the selection of the indicators and the monitoring approach
used to measure the indicators. Also provide any data supporting the rationale and justification. Explain the reasons for any differences between the
verification of operational status or the quality assurance and control practices proposed and the manufacturer's recommendations. (If additional space is
needed,attach and label with the appropriate PSEU designation and pollutant).
Visible emissions were selected as the performance indicator because it is indicative ofoperation of the baghouse in a manner necessary to comply with the
particulate emission standard. When the baghouse is operating properly,there will not be any visible emissions from the exhaust. Any increase in visible
emissions indicates reduced performance of a particulate control device;therefore,the presence of visible emissions is used as the performance indicator.
An inspection and maintenance program was chosen as a performance indicator due to the high reliability of properly maintained baghouses at controlling
particulate emissions.A key element of the program is bag filter reliability,which is why an amoral internal inspection of baghouse was selected as a
performance indicator.
10. INDICATOR RANGES: Provide the rationale and justification for the selection of the indicator ranges. The rationale and justification shall indicate how EACH
indicator range was selected by either a Compliance or Performance Test,a Test Plan and Schedule,or by Engineering Assessments. Depending on which
method is being used for each indicator range,include the specific information required below for that specific indicator range. (If additional space is needed,
attach and label with the appropriate PSEU designation and pollutant):
• COMPLIANCE or PERFORMANCE TEST(Indicator ranges determined from control device operating parameter data obtained during a compliance or
performance test conducted under regulatory specified conditions or under conditions representative of maximum potential emissions under anticipated
operating conditions. Such data may be supplemented by engineering assessments and manufacturer's recommendations). The rationale and justification
shall include a summary of the compliance or performance test results that were used to determine the indicator range and documentation indicating that
no changes have taken place that could result in a significant change in the control system performance or the selected indicator ranges since the
compliance or performant test was conducted and approved by DAQ.
• TEST PLAN AND SCHEDULE(Indicator ranges will be determined from a proposed implementation plan and schedule for installing,testing,and
performing any other appropriate activities prior to use of the monitoring). The rationale and justification shall include the proposed implementation plan
and schedule that will provide for use of the monitoring as expeditiously as practical after approval of this CAM Plan,but in no case shall the schedule for
completing installation and beginning operation of the monitoring exceed 180 days after approval.
• ENGINEERING ASSESSMENTS(Indicator ranges or the procedures for establishing indicator ranges are determined from engineering assessments and
other data,such as manufacturer's design criteria and historical monitoring data,because factors specific to the type of monitoring,control device,or
PSEU make compliance or performance testing unnecessary). The rationale and justification shall include documentation demonstrating that compliance
testing is not required to establish the indicator range.
RATIONALE AND JUSTIFICATION:
The selected indicator range is visible emissions in excess of 20%opacity,which was selected because an increase in visible emissions is indicative ofan
increase in particulate emissions. The initial step to evaluating visible emissions will be conducting a visible/no visible emissions observation because it does
not require a Method 9 certified observer. .
Due to the high reliability of baghouses in this type of application,an indicator range of monthly visual and annual internal inspections is considered
adequate enough to identify potential degradations in bag filter pen fo•mance before failure.As a result of these inspections,corrective actions will be
initiated and repairs made as required.
