DIRECTIONS TO SITE: From FRO, follow traffic circle to second left on Gillespie Street for 0.3 miles. Turn right on Russell Street for 0.5 miles. Turn left on Robeson Street for 2.4 miles. Turn left on Raeford Road, Hwy 401 South for 20.4 miles through Wagram. South of Wagram,NC,take Old Wire Road(NC 144)for 12.3 miles to US74. Follow US 74 West for 39.7 miles through Wadesboro, and turn right(north)onto US52. Go—2 miles, pass Triangle Brick on right, go 1l4 mile, and the entrance to the Valley Protein plant is on the right(656 Little Duncan Rd.) II. SAFETY: Hard hat, safety glasses, safety boots,hearing protection; gloves and a wipe rag are advisable. The greatest hazard to the inspector is either slipping on stairs or burn from a leaking steam pipe. Steam is used extensively, and there are always puddles that reduce boot traction. An inspector is consciously or subconsciously tentative about touching railing at a rendering plant,which could increase the chance of falls. Keep fingers out of your mouth during the inspection, and wash hands thoroughly when finished. III.FACILITY DESCRIPTION: The facility renders chicken feathers and fat for a number of processors. Currently,blood and offal are sent to other plants.They use several rendering methods to make four products: feather meal,pet-food-grade protein meal, feed-grade meal (poultry food additive),and two grades of fat. The majority of the fat is sold as a feed additive but can also be used as boiler fuel when fuel prices warrant. There are five uncontrolled boilers that supply steam to the processes; additionally,boilers B-1,B-2 and B-3 serve as odor control devices. Boiler B-5 is a temporary boiler that hasn't been on site in years. The primary control for the intensive rendering emissions is the evaporation of condensables,then oxidation within the boilers. An alternate scenario is directing non-condensable emissions through the wet scrubber and cross-flow scrubber,normally used only for control of the lower intensity odors from room air. This facility employs—145 workers, including drivers,and operates 24 hours for 5-and one-half days each week;the remaining one- and one-half days are consumed by maintenance and inspections. The facility opens each control device every Sunday for cleaning and inspections. IV. INSPECTION SUMMARY: On 23 February 2022, I, Jeffrey Cole of DAQ FRO,arrived at Valley Protein to conduct an air quality compliance inspection. Before pulling into the facilities parking lot, I drove along Little Duncan Road for 0.5 miles, from the turn off NC Hwy 52 to approximately one quarter mile past the plant.Except for the part of Little Duncan Road that is in front of the plant, I did not detect any rendering or other odors. After arriving back at the plant,I met with James Hodges, Environmental Manager. Mr.Hodges reviewed the FacFinder data and noted that one phone number needed to be updated. This change was made in IBEAM after I returned to the FRO. There are 4,248 gallons of No. 6 fuel oil and 11,258 gallons of saleable animal fat on-site. The previous inspection noted 19,773 gallons of No. 6 fuel oil and 21,650 gallons of saleable animal fat stored on-site. Mr. Hodges explained that the company chose to combust both these fuels(at separate times in Boiler B-4 only) since the last inspection because these fuels had been in the tanks for a long time and the company made a decision to reduce the volume of these older fuels. All of the facility's records of I&M appeared complete,and there were no noted concerns. We next reviewed the facility's latest boiler tune-up records. The facility tunes the boilers semiannually, and the records sent to Mr.Hodges showed the last tune-ups were completed on 20 September 2021. After reviewing the facility's records,Mr.Hodges and I toured the facility. Upon entering the control office,we noted that the facility's process computer showed the longest duration that any material had been waiting on site was—27 hours. Mr.Hodges was unaware of this long duration as normally any load that has been onsite for more than 14 hours requires that management be informed. He was concerned as the permitted limit of hours for the material waiting was 36 hours. Mr. Hodges explained that new personnel were recently hired and training about this permit requirement had not been done. Mr. Hodges contacted me after the inspection and confirmed that the material was processed later that afternoon at 29 hours onsite. All scrubbers were operational,and their gauge readings(flow rate/pressure,ORP)were within the permit limits. The facility was not rendering material during the inspection as the water supply to the boilers was cut off and was under repair.

APPEARED IN COMPLIANCE—The facility was not rendering material during the inspection as the water supply to the boilers was cut off due to a pressure valve malfunction that was preventing water flow. This malfunction was under repair at the time of the inspection. The facility normally fires natural gas but chose to combust 15,489 gallons of No. 6 fuel and 10,392 gallons of saleable animal fat in 2021 to reduce the amount of these fuels in their onsite tanks. The AP-42 emission factor for natural gas is 0.007 lb/mmBtu. Source testing at the facility in April 2001 resulted in a PM emission factor of 0.05 lb/mmBtu while combusting saleable animal fat. The AP-42 PM emission factor for No. 4 fuel oil is 0.05 lb/mmBtu. The AP-42 PM emission factor for No. 6 fuel oil is 0.06 lb/mmBtu. 2. 15A NCAC 2D .0516 SULFUR DIOXIDE EMISSIONS FROM COMBUSTION SOURCES —Sulfur dioxide emissions from the facility's boilers shall not exceed 2.3 lb/mmBtu. The Permittee shall monitor the sulfur content of the No. 6 fuel oil and recycled No. 4 fuel oil by using fuel oil supplier certifications per shipment received;the sulfur content of the No. 6 is limited to 2.1 %and the recycled No. 4 to 2.0%. Recordkeeping and semiannual reporting. APPEARED IN COMPLIANCE—The S02 AP-42 emission factor for natural gas is 0.0006 lb/mmBtu and for 0.5%S No. 2 fuel oil is 0.02 lb/mmBtu. The worst-case fuel is No. 6 at 2.1%sulfur (current fuel certification), would emit S02 at rate of 1.7 lbs/mmBtu. The last test on the facility's No. 6 fuel oil was 0.54%sulfur. This testing was done at the last purchase of No.6 fuel oil was 313114. The last testing of the saleable fat onsite, conducted on 12113121, recorded a sulfur content of 0.009%. 3. 15A NCAC 2D .0521 CONTROL OF VISIBLE EMISSIONS—The visible emissions from the facility's emission sources shall not be more than 20%opacity. The Permittee shall observe the visible emissions from the boilers while firing on No. 6 fuel oil,recycled No. 4 fuel oil,No. 2 fuel oil and animal fat oil,and from the rendering processes daily against"normal." Recordkeeping and semiannual summary reporting. APPEARED IN COMPLIANCE—The facility was not rendering material during the inspection as the water supply to the boilers was cut off and was under repair. There were no visible emissions noted from the scrubber exhausts. In 2021, the company chose to combust 15,489 gallons of No. 6 fuel and 10,392 gallons of saleable animal fat in Boiler B-4 dining separate periods. The facility goes beyond the permit's requirements by performing observations of all boiler stacks on all operational days firing any fuel type since the last inspection. The facility's VE log is well organized and there were no abnormal or excess emissions noted. The company has a Method 9 certified employee on site. The semiannual report was received on 1120122 and indicated compliance. 4. 15A NCAC 2D .0524 NSPS 40 CFR PART 60 SUBPART De—The maximum sulfur content of any fuel oil combusted in Boiler B-3 shall not exceed 0.5%,and the maximum VE shall be 20%. The Permittee shall record and maintain records of the amounts of No. 2 fuel oil combusted during each month and of the sulfur content through fuel supplier certifications. Semiannual reporting. APPEARED IN COMPLIANCE—The facility was not rendering material during the inspection as the water supply to the boilers was cut off and was under repair. Boiler B-3 has only fired natural gas since the last inspection. The semiannual report was received on 1120122 and indicated compliance. 5. 15A NCAC 2Q .0317 AVOIDANCE OF PREVENTION OF SIGNIFICANT DETERIORATION for SOz and CO—Boilers B-1,B-2,B-3 and B-4 shall discharge less than 250 tons of sulfur dioxide and carbon monoxide per consecutive twelve-month period. The Permittee shall record the amounts of natural gas,No.2 fuel oil,No. 6 fuel oil, On Specification No. 4 recycled fuel oil, and saleable animal fat combusted in the boilers each month;the Permittee shall also calculate the amounts of carbon monoxide and sulfur dioxide emitted each month. APPEARED IN COMPLIANCE—The monthly records appear to be complete, and emissions appear to be calculated correctly using the fuel emission factors listed in the facility's annual emissions inventory. The records show the that 572,275 mmcf of NG, 0 gallons of No. 2 fuel oil, 17,796 gallons of No. 6 fuel oil, 0 gallons of off specification, recycled, No. 4 fuel oil and 10,392 gallons of saleable animal fat were combusted in 2021. The following tables show boiler annual (CU2021) emissions and the most recent 12 month emissions based on fuel combusted. �nnutt XY VEtn ssi©t Natural Gas 24.0 0.17 i No. 6 fuel oil _ � � 0.04 �— —� 2.93 — � Saleable Animal Fat 0.001 �U ; �.

The permit allows calculations based on the PSD avoidance(monthly)calculations, divided by 30. APPEARED IN COMPLIANCE—The facility makes daily calculations of SOz emissions based on fuel combusted the previous day. Mr. Hodges noted that the sulfur dioxide emitted from Boilers B-1, B-2, B-3, B-4 and B-5 on 2121122 (based on the PSD avoidance[monthly] calculations, divided by 30)was 426.3 pounds. This is much higher than the 1.1 pounds recorded on 2124121 documented during the previous inspection. Mr. Hodges stated that the combustion of the No. 6 fuel oil in 2021 accounted for this large difference in emissions. This higher level is still far below the permitted limit. 7. 15A NCAC 2D .1111: MAXIMUM ACHIEVABLE CONTROL TECHNOLOGY—For Boilers B-1,B-2,B-3,B-4 and B-5,the Permittee shall comply with all applicable provisions, including the notification,testing, and monitoring requirements contained in Environmental Management Commission Standard 15A NCAC 02D .1111, "Maximum Achievable Control Technology" as promulgated in 40 CFR 63, Subpart JJJJJJ, "National Emission Standards for Hazardous Air Pollutants for Area Sources: Industrial,Commercial, and Institutional Boilers", including Subpart A "General Provisions." These include a one-time energy assessment, a Notification of Compliance Status(NOCS),biennial/triennial or every five year tune-ups,what and how often testing,records,reporting, etc).

For used cooking oil in sealed tankers, no later than 96 hours after being weighed upon arrival at the facility. c. For all other types of raw material not in sealed containers,no later than 36 hours after being weighed upon arrival at the facility. APPEARED IN COMPLIANCE—Storage of material while on-site is tracked electronically. The longest any material was onsite during the inspection was—27 hours. The company has a handwritten log in the scale house where they record any loads that go over 18 hours. Eighteen hours is their warning that something must happen with the load quickly. If a load reaches the 18-hour mark the General Manager and Plant Manager are notified to ensure the load is dealt with. Mr. Hodges explained that this was the first load exceeding the 18-hour mark in the last 3 years. Mr. Hodges was not pleased with the time that this load was onsite and called the appropriate employees to get this load processed quickly. He later explained that new personnel were recently hired and training about this permit requirement had not been done. Mr. Hodges contacted me after the inspection and confirmed that the material was combusted later that afternoon at 29 hours onsite. While the facility was not rendering material during the inspection as the water supply to the boilers was cut off and was under repair, my inspection noted that all scrubbers were operational, and their gauge readings (flow rate/pressure, ORP) were within the permit limits. Venturi C-1 (9 psig minimum) was operating at 11 psig, venturi C-3 (5 psig minimum) was operating at 13 psig. The packed tower scrubber C-4 (3 psig minimum) was operating at 15 psig. Scrubber C-8 (each stage's psig at a 13 psig minimum) was shown operating at 22 psig(Stage 1) and 25 psig(Stage 2). The ORP values were observed to be +817 mV(Packed Tower Scrubber C4) and+418 mV(Stages I and II of Cross-Flow Scrubber C8). The operator's log for checking high fire status, when the boilers are used for odor control, included readings taken and logged during each shift and appeared complete. The facility has a rigorous cleaning and inspection regimen, which exceeds the permit requirement and is completed weekly. Calibrations are completed monthly by Chemtreat, utilizing a chlorine dioxide or a sulfate-based odor oxidizing solution. All the internal duct work including the inside of the scrubbers was cleaned on 02124122. The DAQ has received one odor complaint since the last inspection (on 10121121). This complaint was investigated but the odor noted could not be detected where the complainant had stated the odor had been. Therefore, this investigation was completed with no action taken against Malley Proteins— Wadesboro Division. STATE ONLY REQUIREMENT: B.
