I. DIRECTIONS TO SITE:
Chemours Company-Fayetteville Works is located off of NC Highway 87 in Bladen County. From FRO,head
south on Green Street toward Maiden Lane. At the traffic circle,take the 2nd exit onto Gillespie Street for
approximately 1 mile. Turn right onto the ramp to Elizabethtown and merge onto Highway 87 south. Travel
approximately 15 miles and turn left onto County Line Road,which is the entrance to the facility. Follow the signs
to check in at the security gate.
IL SAFETY CONSIDERATIONS:
The usual FRO safety gear is required(hardhat, safety glasses,safety shoes,hearing protection). Entry into several
areas of the plant requires specialized safety gear. In the HFPO reactor and MMF process areas,personnel are not
allowed to enter unless the process is not operating due to the possibility of explosion hazards of the chemical
reaction process.
III. FACILITY DESCRIPTION:
Chemours Company-Fayetteville Works is a chemical manufacturing facility located in Bladen County. The
facility was formerly owned by DuPont. The facility employs approximately 320 employees and 60 full-time
contractors on a 24 hr, 7 day per week basis. The facility consists of four individual manufacturing plants,a boiler
house and a waste treatment operation. Several processes have PSD avoidance conditions. The facility has two
permanent boilers onsite,one permanent boiler which is permitted but not yet constructed,and one permitted
temporary boiler.
IV. INSPECTION SUMMARY:
On Thursday,February 24,2022,I,Evangelyn Lowery-Jacobs,of the DAQ Fayetteville Regional Office,conducted
a compliance inspection with Christel Compton,Program Manager. Ms. Compton reviewed the FacFinder sheet and
noted that all information is correct.
Facility records were reviewed for emissions calculations and control device inspections. There are extensive
electronic records for the facility operations available on the local computer area network. Ms.Compton was able to
display PSD data and other facility processing and operational records via computer for review. For the operating
areas,screenshots of flow rates and pressure drops in scrubbers were provided by technicians available in the control
rooms of the respective areas. Boilers (PS-A and PS-B) were operating, firing natural gas. The third permitted
boiler (PS-C) is not yet constructed. The permitted temporary boiler(PSC-Temp) is not currently on site and was
not on site during 2021. The Lime Processing System (ID Nos.NS-RI and NS-R2)were not operating during the
inspection but had been operational earlier that morning. All other processes were in operation during the
inspection. I observed zero visible emissions from each of the operating source emission points.

VI. APPLICABLE AIR QUALITY REGULATIONS:
Regulations will be discussed for each of the various manufacturing processes as listed on the current air permit.
❖ Powerhouse(Boilers PS-A,PS-B,and PS-C)
The facility is permitted to operate one Natural Gas/No.2 fuel oil-fired boiler(139.4 mmBtu/hr maximum heat
input,PS-A),one Natural Gas/No.2 fuel oil-fired boiler(88.4 mmBtu/hr maximum heat input,PS-B),and one
Natural Gas/No.2 fuel oil-fired boiler with low-NOx burner(97 mmBtu/hr maximum heat input,PS-C). The
third boiler(PS-C)has not yet been constructed. According to Ms. Compton,this boiler will not be constructed
anytime soon,as there is no current need for additional steam capacity. Both of the existing boilers are
currently combusting natural gas. The larger boiler(PS-A)has a steam capacity of 113,000 pounds of steam
per hour(139.4 mmBtu maximum heat input)and was manufactured in 1969. The smaller boiler(PS-B)was
manufactured in 1982 with a steam capacity of 72,000 pounds per hour(88.4 mmBtu/hr maximum heat input).
They are both pre-NSPS boilers;however,Boiler PS-B has a PSD avoidance condition for NOx and S02.
Boiler PS-C will be subject to NSPS Subpart Dc when constructed. Chemours has a facility-wide PSD S02
emissions limitation of 702.5 tons per consecutive 12-month period.

• FPS/IXM Process Area
The operation produces a variety of relatively uncommon monomer and polymer chemicals. Some of the
monomers are shipped offsite,while others are used onsite in the production of various polymers. The
polymers are shipped offsite or used onsite to produce NafionO membrane material. A principal use of this
membrane is in the electrolysis cells for production of chlorine and sodium hydroxide at chloro-alkali plants.
The two waste gas scrubbers located at the FPS/IXM process area are used to control the emissions of various
pollutants including hydrogen fluoride and other acid fluorides. The HFPO,Vinyl Ethers North and South,and
the IXM Resins processes(ID Nos.NS-A,NS-B,NS-C, and NS-G)are subject to the Miscellaneous Organic
NESHAP, Subpart FFFF and are classified as existing sources under this regulation.

P. 15A NCAC 02D.I I I I MAXIMUM ACHIEVABLE CONTROL TECHNOLOGY(MACT)40 CFR
Part 60 Subpart FFFF: MISCELLANEOUS ORGANIC NESHAP(MON)—The HFPO,Vinyl Ethers
North and South,and the IXM Resins processes(ID Nos.NS-A,NS-B,NS-B-2,NS-C,NS-C-2,NS-G-1,
and NS-G-2)must comply with all provisions of this MACT. The MON requires 99%control efficiency
for some Group 1 sources;however,Chemours determined that their sources are not subject to the stricter
requirements of a control device. The Permittee shall monitor and inspect all the valves,pumps,
compressors,agitators,and connectors for leaks using the instrument monitoring methods described in 40
CFR 63.1023(b)-(c). All equipment affected by the leak requirements shall be identified. The Permittee
shall create and retain a record of the monitoring schedule for each process unit. If a leak is identified,it
shall be repaired as provided in the repair provisions of this section. After a leak has been repaired,the
valve shall be monitored at least once within the first 3 months after its repair. This requirement is in
addition to the monitoring required to satisfy the definition of repaired and first attempt at repair. The
required periodic monitoring may be used if it satisfies the timing requirement of this condition. The
Permittee shall repair each leak detected as soon as practical,but not later than 15 calendar days after it is
detected. The facility operates two process heat exchangers that are subject to the MON. Monitoring for
presence of a leak in a heat exchanger system requires that three samples of both the cooling water entrance
to and exit from the heat exchanger be monitored for the presence of hazardous air pollutants monthly for
the first six months of operation and quarterly thereafter. A semi-annual summary report is required.
APPEARS IN COMPLIANCE—The scrubbers currently controlling the HFPO, Vinyl Ethers North and
South, and the IXM Resins processes(ID Nos.NS-A,NS-B,NS-B-2, NS-C,NS-C-2,NS-G-1, and NS-G-2)
meet the control efficiency requirement. The scrubbers were tested at 99.6%efficiency in August 2003
(further data indicates that the efficiency was only 99.1%). Initial notification was received on 2 March
2004. However, no controls are required for this facility based on HAP content, THE values, and other
various parameters. The facility has an extensive LDAR program, and inspects all the valves,pumps,
compressors, agitators, and connectors for leaks on a monthly basis. Records are available at the site.
Chemours Company—Fayetteville Works
Compliance Inspection Report
Page 9 of 16
Each affected unit has a physical tag for equipment identification. Three samples of both the cooling
entrance and exit are taken at the heat exchangers to analyze for leaks on a monthly basis. The facility
also submits a semi-annual report for MACT Subpart FFFF. There were no deviations from the emission
limits, operating limits, or work practice standards during 2021. The last semi-annual summary report
was received at FRO on 0112612022. Amore extensive AIL4CT FFFF report is submitted to EPA and FRO
also, which includes several items not required in the Title V permit but are required by the MACT. The
facility has a "zero leak"policy. If a leak is discovered, it is fixed ASAP, even if the process must be shut
down. No delay of repair scenarios are normally permitted by the facility's LDAR policy, but they are
allowed under the MA CT regulation. According to the facility records, no delays of repair occurred in any
of the facility processes during 2021.
Q. 15A NCAC 02Q.0519(a)(7)and CONSENT ORDER(State Enforceable Only)—The permittee shall

❖ Polymer Processing Aid(PPA)Process(all sources labeled with AS-and ACD-)
The polymer processing aid process,formerly the ammonium perfluorooctanoate(APFO)process,began
operation in December of 2002. Formerly,the Polymer Processing Aid reaction process used perfluorooctanoic
acid(PFOA-brought in by truck in its iodide/salt form)reacted with sodium hydroxide(stored in totes)to form
the acid fluoride. The acid fluoride was then reacted with ammonia to produce the ammonium salt. Fuming
sulfuric acid(oleum)is received by truck and used as a solvent in the process. Currently,APFO and the
associated(PFOA),also known as C8,are not regulated as toxic or hazardous air pollutants. However,the EPA
has been reviewing the chemical with the possibility of its designation in the future as a regulated pollutant. Due
to historical pollution and health effects concerns and recent controversy regarding the DuPont facility in West
Virginia,and the recent activities by the U.S.EPA to develop and review toxicity data for this chemical,the DAQ
file includes several documents and articles related to APFO,PFOA,or C8. The APFO process was subject to the
112(r)chemical accident prevention program for oleum. DuPont made a decision to eliminate APFO by 2015,
and therefore the PPA process at the Fayetteville Works was modified,and no longer produces APFO and is no
longer subject to 112(r)written risk management plan requirements. The replacement for APFO is HFPO Dimer
Acid,which is currently also under scrutiny.
R. 15A NCAC 02D.1100 CONTROL OF TOXIC AIR POLLUTANTS(State Enforceable Only)—
Emissions from the PPA facility shall be controlled by a wet scrubber. The liquid flow rate in the packed
bed section shall be a minimum of 30 gallons per minute and the differential pressure across the bed shall
be a maximum of 12 inches of water,based on three-hour averages. An alarm is required for the pressure
monitoring. Records of all inspections shall be kept in a logbook. No reporting is required.
APPEARS IN COMPLIANCE—The scrubber is interlocked so that the system will shut down, almost
instantaneously, if the parameters are exceeded. The facility will go into shutdown mode if the three-hour
average is less than 30 gpm or pressure exceeds 5 inches of water. The system is set up such that upon
startup after an extended shutdown, the scrubber must be operated for three hours to establish the
minimum 3-hour average prior to allowing the startup of the remaining equipment. The polymer
processing aid chemical is a surfactant; therefore, the AP increases occasionally due to `suds'in the
scrubber. The liquid f owrate during the inspection was 37.9 gpm, and the pressure drop across the
scrubber bed was-0.9"H20. The last internal inspection of the scrubber was performed on 0810212021.
The last carbon bed filter inspection was 1211312021.
❖ Wastewater Treatment Area(all sources labeled with WTS-and WTCD-)
For the wastewater treatment operations,the Title V permit specifies two rotary sludge dryers controlled by an
impingement-type wet scrubber with mist eliminator. The Miscellaneous Organic NESHAP(MON)also
addresses emissions from wastewater. With respect to quantity of emissions,methanol is the most significant
air pollutant from the wastewater treatment operation.
S. 15A NCAC 02D.1806 CONTROL AND PROHIBITION OF ODOROUS EMISSIONS—The
wastewater treatment facility shall 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 property boundary. The sludge dryers shall be
controlled by a caustic injection scrubber. An I&M logbook is also required for the scrubber. No reporting
is required.
APPEARS IN COMPLIANCE—Odorous emissions from the sludge dryers are controlled by a scrubber
utilizing potassium hydroxide solution. Wastewater treatment odors were not noted at boundary lines. The
sludge dryers are located inside a building. The facility keeps maintenance records for the scrubber in
their electronic maintenance program. The most recent inspection of this scrubber was conducted on
0910912019. The manufacturer recommends inspection every 5 years. Ms. Compton stated that no odor
complaints have been received by the facility. FRO has not received any odor complaints relating to this
facility.
