FACILITY DESCRIPTION: Homwood, Inc. is a textile company that warps,weaves, dyes yarn,heat- sets(tenter frame finishes) and doffs(textures)nylon and polyester knit fabrics. They produce baseball uniforms, automobile seat fabric, cloth for reverse osmosis water purification, gauze liners for tennis shoes,and cowboy shirts to name a few. This process may be divided into several distinct operations as follows: Warping: Yarn is spun onto a single spool for processing in the knitting room. Yarn may also be draw warped which draws the diameter of the yarn down by heat and tension, and effectively reduces the size of the yarn. Knitting Room: Spools go onto a mandrel that feeds the knitting machines. Middle Warehouse: This is where both finished and unfinished fabric is stored until either future processing is done or shipped to the customer. Dye House: Dye is added to the fabric in one of two processes, beam orjet dying. In beam dying,fabric is wound onto a beam with holes that allow the dye to pass through. The dye solution is pumped from the rear of the chamber and passes through holes in the beam and out through the fabric. In jet dying,the cloth is pulled through a tube in the top of the dye chamber by means of a roller and is constantly in motion through a dye water solution in the bottom of the chamber. Finishing: Cloth is passed through one of four tenter frames which heat sets the fabric to reduce shrinking and stretching; chemicals which stiffen or coat the material may be added. Napping: One of three things may be performed on the material during this process. The fabric will be napped which gives it the appearance of fleece, or shearing which cuts off the top of the fleece, or sueded which sands the fabric. Mist Eliminators: The exhaust air from the tenter frames flows through a pre-filter that takes out some of the dry particles with a one-inch fiberglass mesh using two trays to pass the air through. In Condenser/Mist Eliminator(ID No. CD-2),the air then passes over four(4)cold water coils and six(6) spray rings that both condense the vapor prior to the mist eliminator. In Condenser/Mist Eliminator(ID No. CD-1),the air passes over six(6) spray rings that help condense the vapor prior to the mist eliminator. There are no cooling coils in CD-1. Both mist eliminators house sixteen(16)two-inch wire mesh cylinders that are each surrounded by a fiberglass mesh. The condensed vapor passes through the center of these filter tubes and then proceeds out the stack. The rinse water is collected at the bottom of each collector unit and sent through oil/water separators to a single holding tank for collection and disposal. Prior to the units being shut down for cleaning,jet nozzles located at the bottom center of each filter tube are used to spray wash water into each. The facility employs about 360 people and operates 24 hours per day, 6 days per week, 52 weeks per year.

INSPECTION SUMMARY: On 9 April 2019, I Jeffrey Cole and Evangelyn Lowery-Jacobs of FRO DAQ,conducted a compliance inspection of Homwood,Inc. in Lilesville, Anson County. The facility was operating at the time of the inspection. Upon approaching the facility from the front parking area we did not detect any visible emissions from the two Condenser/Mist Eliminators and the rear of the facility. However, since it was a cloudy overcast day we proceeded to the rear of the facility to observe the two Condenser/Mist Eliminator stacks. From the rear of the facility we observed visible emissions from Condenser/Mist Eliminator CD-1. We immediately went to the facility's front reception area to begin our inspection and to specifically get to a proper Method 9 observation location on the facility's roof. We were told that the facility contact, Mr. Dale Kelly, was out running an errand and not available. I told the receptionist that we needed an escort immediately to begin our inspection. We were quickly greeted by Mr. Jay Stewart, Maintenance Supervisor,who escorted us to the roof. We found a spot on the roof that met the requirements for a proper Method 9 observation and Ms. Lowery-Jacobs began the observation. During the observation Mr. Kelly met us on the roof. I told Mr. Kelly that we would speak with him after we completed our observation. We were able to record a 24- minute Method 9 observation before rain forced us off the roof. Before leaving the roof I pointed out to Mr. Kelly the opacity we had been observing from Condenser/Mist Eliminator CD-I. He stated that he had seen visible emissions around 27 March 2019 but had not had the chance to observe from the roof or to inquire from his maintenance people what might be the cause. While on the roof, we also noted what appeared to be VE at—5%opacity from the stack for Condenser/Mist Eliminator(ES ID No. CD-2). Upon reentering the facility,we went to the control panel, on the inside wall near the Condenser/Mist Eliminators, which graphically displays all of the unit's parameters. These parameters were as follows: Condenser/Mist Eliminator(ES ID No. CD-1) FME Inlet Temperature(°F) 250 FME Outlet Temperature(° F) 111 Pre-Filter Differential Pressure(Inches of H2O) 0.15 Overall(i.e.,Post-Filter) Differential Pressure (Inches of H2O) 10 Condenser/Mist Eliminator(ES ID No. CD-2) FME Inlet Temperature(°F) 277 FME Outlet Temperature(°F) 149 Pre-Filter Differential Pressure(Inches of H2O) 3.4 Overall(i.e.,Post-Filter)Differential Pressure (Inches of H2O) 2.3 I noted to Mr. Kelly that maintenance log for CD-1 showed that the overall differential pressure was reading 10 inches of H2O for 7 separate readings on 7 and 8 April 2019 while the column heading of the log page showing that a pressure in the"good"range was between 3 to 6 inches of H2O. I also noted that there was only a"93"noted in the notes section of the log for each operational day for each of the 7 separate readings. I asked Mr. Kelly what the"#3"stood for and he said that stood for the source,ES ID No. Tenter 3 being the only source in operation when CD-1 was in operation during that time period. I asked where the person filling out the log would have recorded a problem or its resolution and Mr.Kelly stated it should be in the notes column of the log. After this we continued with our inspection. We then went to Mr. Kelly's old office where the facility keeps their maintenance records. Mr. Kelly was able to produce all maintenance and inspection records I requested and was able to produce the production records and the natural gas usage records both monthly and annually for 2018. Mr. Kelly verified the FacFinder data and he stated that no changes to the FacFinder were necessary. Mr. Kelly was able to produce the facility's latest air quality permit. I asked Mr.Kelly if fuel oil was combusted since the last inspection and specifically during the most recent annual tune-up on the boiler. Mr. Kelly explained that facility had not had its natural gas supply curtailed and had not performed a tune-up on their permitted boiler(ES ID No. Main-031)since the last inspection in April 2018. Mr. Kelly stated that they planned to perform a tune-up in late May 2019 on both natural gas and No. 2 fuel oil. I reminded Mr. Kelly that his Method 9 reading exemption determined during his last Method 9 testing had expired on 3 June 2018 and that they would need to have Method 9 reader conduct a VE observation during the tune-up when firing No. 2 fuel oil. Mr. Kelly stated that he understood this requirement. We then proceeded to the boiler room where I observed the Natural gas/No. 2 fuel oil-fired boiler(ID No. Main-031),the Natural gas-fired therminol heater(ID No. I-Main-058)and the Natural gas/No. 2 fuel oil- fired boiler(ID No. I-03)both operating on NG at 0%opacity. The Natural gas/No. 2 fuel oil-fired therminol heater(ID No. I-01)was not operating. We then had an exit conference with Mr. Kelly where I told Mr.Kelly that he would be receiving a letter from our office about the apparent emissions violation observed. Mr.Kelly stated that he would have his maintenance people open up and inspect Condenser/Mist Eliminator CD-1 during their facility's shutdown and determine why emissions were exceeding their permitted limits. He also stated he would let us know in an email of the results of the inspection. On 15 April 2019,Mr.Kelly emailed me copies of the inspection work orders dated 11 through 12 April 2019 showing that the company's maintenance personnel had entered the Condenser/Mist Eliminator CD-1 to ascertain what was causing the excess emissions. They had removed and replaced all of the fiberglass filters(which surround metal cages)with clean filters. These clean filters had been pre-staged for their annual(done semiannually)inspection and maintenance scheduled for July 2019. In examining the removed filters,they found that a number of the filters had a hard coating and would not allow airflow to pass through them and thus reduce particulate emissions. Mr. Kelly stated that their normal periodic maintenance procedure for the condenser/mist eliminator was for the maintenance crew to spray the filters (while in place)with a cleaning solution and then thoroughly rinsing each filter. This is done at the end of each week's production. He suspects that some of the filters weren't rinsed thoroughly and the heat from the tenter frames entering the condenser/mist eliminator hardened the chemical solution on the filters. This reduced the unit's control effectiveness and the air flow found ways to bypass the plugged filters causing the emissions. Mr.Kelly emailed photos of the stack operating after the filter change and no visible emissions can be seen in the pictures. Mr.Kelly also stated that he had spoken with all the maintenance personnel and reminded them of the proper procedures for cleaning and rinsing the filters. He also told all personnel entering control device parameters in the log to make sure the parameters they were recording in the log is within the log column's proper range and to advise the maintenance supervisor if they are not. He also told them to note any trends towards the range limits and to advise the maintenance supervisor of such. V.

Compliance was determined during the most recent permit review based on operating the source as described in the permit conditions. No changes have been made to operations since that determination 4. 15A NCAC 2D .0516—SULFUR DIOXIDE EMISSIONS FROM COMBUSTION SOURCES— S02 emissions from the facility's combustion sources shall not exceed 2.3 lb/mmBtu. APPEARED IN COMPLL4NCE: The facility combusts primarily natural gas, but may combust No. 2 fuel oil if necessary. The facility only accepts ultra-low su fNr diesel(ULSD), as verified by fuel certifications. AP-42 S02 emission factors for natural gas and ULSD are 0.00061b/mmBtu, and 0.002 Zb/mmBtu respectively. 5. 15A NCAC 2D .0521 —CONTROL OF VISIBLE EMISSIONS—Visible emissions from each emission source manufactured after 1 July 1971, shall not exceed 20%opacity when averaged over a six-minute period. APPEARED IN VIOLATION.• Based on the history of this facility we made it a paint to drive around the facility before entering the facility to note any VE emissions present. We noted visible emissions from Condenser/Mist Eliminator CD-1. We entered the facility and proceeded to the roof to conduct a proper Method 9 observation. We were able to record a 24 minute Method 9 observation before rain forced us off the roof. The Method 9 observation resulted in 3 six-minute averages above the facility's 20%opacity limit(30.0016, 30.6%and 31.095). We also noted approximately 5%opacity from the stack for CD-2. 6. 15A NCAC 2D .0524—NEW SOURCE PERFORMANCE STANDARDS(Subpart Dc)—The facility's boiler(Main-031)is subject. Fuel sulfur content<0.5 wt.% and monthly records of fuel usage. VE<—20% opacity. Initial start-up testing, and periodic testing for visible emissions when switching from natural gas to fuel oil. Semiannual reporting. APPEARED IN COMPLL4NCE: The facility maintains the required fuel records, which show no _/ael oil combustion in the last 12 months, and fisel certifications show that the facility only combusts ULSD. Mr. Kelly stated that they planned to perform a tune-up in late May 2019 on both natural gas and No. 2 fuel oil. I reminded Mr. Kelly that his Method 9 reading exemption determined during his last Method 9 testing had expired on 3 June 2018 and that they would need to have Method 9 reader conduct a VE observation during the tune-up when firing No. 2 f gel oil. Mr. Kelly stated that he understood this requirement. 7. 15A NCAC 2D .0535—NOTIFICATION REQUIREMENT—Notify DAQ in the event of excess emissions lasting longer than 4 hours. APPEARED IN COMPLL4NCE. Mr. Kelly stated that the facility has had no exceedances, breakdowns, or abnormal conditions requiring notification before our inspection. 8. 15A NCAC 2D .0540—PARTICULATES FROM FUGITIVE DUST EMISSION SOURCES— Fugitive dust emissions shall not cause/contribute to substantive complaints or excessive VE across property boundaries. APPEARED IN COMPLL4NCE: No fugitive dust concerns were noted during the inspection.All roads are paved, and there have not been any complaints received by DAQ. Mr. Kelly stated that there had been no dust complaints in the past year. 9. 15A NCAC 2D .0611—CONDENSER/MIST ELIMINATOR REQUIREMENTS—Annual internal and structural integrity inspections of CD-1 and CD-2. Change pre-filter weekly. Monitor pressure drop daily and implement wash procedures when mist eliminator AP reaches 7.5-8.0"H2O, or when water coil AP reaches 3.0"H2O. Weigh oil and particulate collected in the mist eliminator weekly. APPEARED IN VIOLATION: The facility monitors pressure drop across the mist eliminators during each shift, and records the values in a logbook. All values in the log book were below the level which would require a wash procedure except for the last 2 days before our inspection on 7 and 8 April 2019 for mist eliminator CD-1. For those 2 days the facility recorded 7 separate readings of 10 inches of H2O without any comments as to these readings being out of range. Also, the facility did not implement wash procedures when mist eliminator CD-1's AP reached 7.5-8.0 inches of H2O as required by their permit. We observed mist eliminator CD-01 (controlling ES-03 and ES-04[when operatingi) at a AP of 10 inches of H2O during our inspection with opacity of 30 to 35%. We observed a mist eliminator CD-02 (controlling ES-01 and ES-02) at a AP of 2.33"of H2O. Mr. Kelly also stated that he had observed what appeared to be high opacity on 27 March 2019 but had not had time to investigate. The mist eliminators are also inspected semiannually with the most recent internal inspections occurring on 5 January 2019 for CD-1 and 17 February 2019 for CD-2. The facility performs weekly maintenance on both mist eliminators. The last weekly inspection on CD-01 was on 29 March 2019 and the last weekly inspection on CD-02 was on 31 March 2019. However, the weekly inspection on 29 March 2019 failed to detect the hardened filter issue discovered after our inspection in CD-01 (see inspection summary). 10. 15A NCAC 2D .0958—WORK PRACTICES FOR SOURCES OF VOCs—Permittee shall adhere to work practices as delineated in the permit. APPEARED IN COMPLIANCE. During this inspection, lids were on tight and all cleaning rags were properly stored. This stipulation will be removed from the permit at next permit opening since it applies only in non-attainment areas and Anson County is in attainment. 11. 15A NCAC 2D .1806—CONTROL AND PROHIBITION OF ODOROUS EMISSIONS— Permittee shall not cause or contribute to objectionable odors beyond the property boundary. APPEARED IN COMPLL4NCE: No objectionable odors were noted as I approached the facility, nor were there any noticeable odors while inside. Mr. Kelly stated that there had been no odor complaints in the past year. 12. 15A NCAC 2Q.0102—FEDERAL AND STATE RULES APPLICABLE TO EXEMPTED SOURCES—Insignificant boiler, I-Main-058, is subject to the requirements of NSPS Subpart Dc. APPEARED IN COMPLIANCE: I discussed the fact that boiler (ID No. I-Main-058) is subject to NSPS Subpart Dc with Mr. Kelly. The boiler is only capable of firing natural gas, and the facility keeps appropriate records. 13. 15A NCAC 2Q .0315—SYNTHETIC MINOR FACILITIES—Operate within the following limits to maintain S02 emissions less than 100 tons annually: 1)Amount of No. 2 fuel oil combusted <2,800,000 gallons per consecutive 12-month period; 2) sulfur content of No.2 fuel less than 0.5%. Annual reporting. APPEARED IN COMPLIANCE: Records indicate the facility combusted no No. 2 fuel oil since their last inspection. Fuel usage is tracked by taking monthly measurements of the fuel storage tank levels. Fuel certifications were available, and show that the facility only receives ULSD. The annual report was received on time on 2 January 2019, and indicated compliance. 14. 15A NCAC 2Q .0317—AVOIDANCE CONDITION FOR GACT 6J—The Permittee shall only fire liquid fuels in Main-031 for periodic testing and during curtailments, gas interruptions, or start- ups. APPEARED IN COMPLIANCE: The facility normally fires boiler (ID No.Main-03) with natural gas. Mr. Kelly explained that facility natural gas supply had not been curtailed since their last inspection. 15. 15A NCAC 2Q .0711—EMISSION RATES REQUIRING A PERMIT—Emissions of toxic air pollutants shall not exceed the following allowable emission rates: 0.96 Ib/hr for acetic acid,and 0.04 lb/hr for formaldehyde.
