MACT/GACT: The facility is subject to GACT 6J,though this is not currently in the permit. The facility completed the one-time Energy Assessment on 07-08 November 2013, submitted the NOCS on 03 June 2014,and is conducting boiler tune-ups semiannually with the last tune-ups being performed on 1 September 2018. A copy of the biennial certification was on-site,and was prepared on time. U. DIRECTIONS TO SITE: From FRO,take US 401 South through Wagram. South of Wagram,take Old Wire Road(NC 144)to US74. Follow US 74 west through Wadesboro,and turn right(north)onto US52. Go a few miles,pass Triangle Brick on right,go'/a mile,and the entrance to the Valley Protein plant is on the right. Proceed down the road to the driveway to the office building on the left side of the parking lot/driveway. M. 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. IV. 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—130 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. V. INSPECTION SUMMARY: On 29 October 2018,I,Jeffrey Cole of DAQ FRO,arrived at Valley Protein to conduct an air quality compliance inspection. I noted slight rendering odor prior to entering the facility gate,and light odors while on site. I met with James Hodges, Environmental Manager. Mr.Hodges reviewed the FacFinder data, and noted that Mr.Bivens,who was listed as authorized and facility contact was no longer employed at the facility. Mr.Hodges updated those contacts and these changes have been made in IBEAM. I reviewed the plant's records which were very well-organized and are kept up-to-date. The plant combusts natural gas exclusively unless curtailed or for testing, during which saleable fat is combusted. The facility fired fat for testing for four days 30 October—2 November 2016, and again in January 2017, during a curtailment. VE observations during these times indicate that there were no visible emissions. The plant has not had its natural gas supply curtailed since the last inspection on 26 October 2017. The facility has not accepted any fuel oil in years,and there was none on-site at the time of the inspection. All of the facility's records 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 1 September 2018. After reviewing the facility's records,Mr. Hodges and I toured the facility. The facility was not rendering any material during the inspection. At the time of the inspection,the facility's process computer showed the longest duration that any material had been waiting on site was—4 hours. All scrubbers were operating at the time of the inspection. The facility boilers ES ID Nos. B-1,B-2 and B-3 were all operating on natural gas,with zero opacity noted. All three of these boilers were set at"pin position 1" during the inspection. When the boiler is in"pin position 1,"it is considered low-fire, and the damper to the boiler is completely closed,meaning all vapor is directed to the packed tower scrubber. "Pin position 2"and higher is consider mid to high fire, and the damper to the boiler is fully open while the scrubber damper is completely shut. While in this state,the scrubber is idle and is in standby in case vapors need to be directed back away from the boilers. While the scrubber is idling,the flow rate,water pressure, chemical concentration level and ORP>300 mV are maintained. All scrubbers were operational and their gauge readings(flow rate/pressure,ORP)were within the permit limits. No odor was noted on the nearby roads when leaving the facility. VI.

APPLICABLE AIR QUALITY REGULATIONS: A. 15A NCAC 2D.0503 PARTICULATES FROM FUEL BURNING INDIRECT HEAT EXCHANGERS—Emissions of particulate matter from boilers into the atmosphere shall not exceed 0.367 lb/mmBtu for boilers B-1 and B-2, 0.318 lb/mmBtu for boiler B-3, 0.30 lb/mmBtu for boiler B-4, and 0.28 lb/mmBtu for boiler B-5. APPEARED IN COMPLL4NCE—The facility has only combusted natural gas, and some saleable fat in 2016. The AP-42 emission factor for natural gas is 0.0071b/mmBtu. Source testing at the facility in April 2001 resulted in a PM emission factor of 0.05 lb/mmBtu while combusting saleable fat. B. 15A NCAC 2D .0516 SULFUR DIOXODE 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 INCOMPLIANCE— The facility fires natural gas exclusively, and will combust saleable animal fat during testing and curtailment; there is no fuel oil on-site. Some saleable fat was combusted for testing in the period of 30 October—02 November 2016, and again in January 2017 during curtailment, however they have combusted no saleable fat since the last inspection (26 October 2017). The semiannual report was received on 11 July 2018, and indicated compliance. C. 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—Boilers B-1, B-2, and B-3 were operating on natural gas in low fire mode (pin position])with zero visible emissions during the inspection. There were no visible emissions noted from the scrubber exhausts. The facility's is performing observations and their VE log is well organized and there were no abnormal or excess emissions noted. The semiannual report was received on 11 July 2018, and indicated compliance. D. 15A NCAC 2D.0524 NSPS 40 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 INCOMPLIANCE—No fuel oil has been combusted since the last inspection. There is no fuel oil currently on-site. E. 15A NCAC 2Q.0317 AVOIDANCE OF PREVENTION OF SIGNIFICANT DETERIORATION for S02 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 animal fat oil 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 are complete, and emissions appear to be calculated correctly using the emission factors listed in the permit. S02 emissions while firing natural gas are inconsequential with the monthly emissions averaging—0.008 tons Aug 16 through Dec 17). CO emissions were consistently around two tons per month and the 12-month rolling total equal to 19.9 tons from Aug 16 through Dec 17. F. 15A NCAC 2D .0501 EMISSION CONTROL STANDARD—The daily emission of sulfur dioxide from boilers B-1, B-2,B-3,B-4 and B-5 shall not exceed 3,644.49 pounds per day. The permit allows calculations based on the PSD avoidance(monthly)calculations,divided by 30. APPEARED INCOMPLIANCE—The facility makes daily calculations of S02 emissions based on fuel combusted the previous day. Sum content of fuels is so low that average daily S02 emissions are typically less than one pound. G. 15A NCAC 2D.0515 PARTICULATES FROM MISCELLANEOUS INDUSTRIAL PROCESSES—Emissions of particulate matter from the feather hydrolyser(ID No. E9), rotary steam tube dryer(ID No. E6),feather press(ID No. E10), rendering process(ID No. El), and fluidizer tank(ID No. E10), shall be controlled by a series of control devices(venturi scrubbers, cyclones,and mist eliminators)and shall not exceed those calculated by E=4.10 * P 1_61,where E is the allowable emission rate in lb/hr;this is accomplished by properly maintaining the control devices. The Permittee shall perform a monthly visible inspection, including all ductwork, and an annual internal inspection of condensers and venturi/packed tower scrubbers. APPEARED IN COMPLLANCE—During the inspection, all control devices were operating. Control devices are typically inspected more frequently than is required; internal inspections are conducted weekly for all control devices during cleaning with the exception of the facility's condensers which are inspected internally on a semiannual basis. Monthly external inspections are conducted and recorded as required. No recent issues have been uncovered during inspections. H. 15A NCAC 2D .0539 ODOR CONTROL FOR FEED INGREDIENT MANUFACTURING PLANTS—The Permittee shall ensure that odorous emissions are controlled by control devices as listed in the permit and the Permittee shall install,operate and maintain parameter measuring and recording devices for these devices. All gases from plant room air, feather and blood rendering,and rendering process shall pass first through the condensers and then be incinerated at 1200 degrees for 0.3 seconds while the boilers are not in low fire(or treated in an equally effective manner. All expeller units shall be properly hooded and all exhaust gases directed to odor control equipment. The Permittee shall take reasonable precautions to prevent odor discharge during handling,transportation and storage of incoming materials. The Permittee shall ensure that all odor control devices are inspected,maintained and operated properly; external inspections monthly, scrubber nozzles cleaned monthly,generation units calibrated monthly,and a semi-annual internal inspection for all control devices. The Permittee shall ensure the venturi (C-1)inlet water pressure at a 9 psig minimum,the venturi (C-3)inlet water pressure at a 5 psig minimum,the packed bed scrubber(C-4)inlet water pressure at a 3 psig minimum,the cross-flow (C-8)generation unit at a+300 mV ORP minimum and the scrubber inlet water pressure at a 13 psig minimum. The Permittee shall monitor the boiler operating parameters once per day for confirmation of boiler operation above low-fire if being used for odor control. The Permittee shall record all parameters, inspections and maintenance in a logbook. APPEARED IN COMPLIANCE—I noted a slight rendering odor at the street as I entered the premises. The only noticeable odor on-site was directly outside the rendering buildings. During the inspection, I noted operating parameters on the control equipment as follows: Venturi C-1 (9 psig minimum) was operating at 11 psig, venturi C-3 (5 psig minimum)was operating at 9 psig. The packed tower scrubber C-4(3 psig minimum)was operating at 6.5 psig. The inlets to crossflow scrubber C-8(13 psig minimum) were operating at 28 psig(1'stage) and 28 psig(2"d stage). The ORP values were observed to be +683 in(packed tower scrubber C4)and+575 in (stages I and II of cross flow scrubber C8). The pressures and ORPs are monitored and recorded each shift in addition to being continuously logged electronically;all showed compliance. The operator's logfor checking high-fire status, when the boilers are usedfor odor control, included readings taken and logged during each shift and appeared complete. Storage of material while on-site is tracked electronically, and the longest any material was on-site during the inspection was—4 hours. The facility has a rigorous cleaning and inspection regimen, which exceeds the permit requirement and is completed weekly. Calibrations are completed monthly by Chemtreat, and the required `ActXone"chemical was in use. I. 15A NCAC 2Q.0317 AVOIDANCE CONDITION FOR 15 A NCAC 2D .1100: CONTROL OF TOXIC AIR POLLUTANTS—The Permittee shall only combust recycled No.4 fuel oil that meets the specifications listed in the permit. The Permittee shall record the amount of recycled No.4 delivered to and combusted at the facility and retain the results of analytical testing. APPEARED INCOMPLIANCE—Zero recycled No. 4 has been purchased or combusted since 2005. There is no recycled oil on-site. J. GENERAL CONDITION"I"—REPORTING REQUIREMENTS FOR EXCESS EMISSIONS AND PERMIT DEVIATIONS—The Permittee shall report excess emissions in accordance with 15A NCAC 2D .0535, and report any permit deviations quarterly. APPEARED EV COMPLIANCE— Mr. Hodges is aware that the permit requires reports of excess emissions and of deviations, and submits reports if required. A notification was received on I May 2018, indicating that,from 6:00-11:00 PM on 8 May 2018, a malfunction of chemical feed lines occurred which led to ORP being low out of specification for cross flow scrubber (CD ID No. C-8)for greater than four hours. Subsequent inspection discovered that there were blockages in the rotameter and chemical feed lines which restricted the chemical flow to the scrubber. The rotameter and the chemical feed lines were disassembled, cleaned out, and reassembled and ORP was restored. The company stated that they were unaware of any excess emissions during the event and had received no odor complaints. DAQ responded on 16 May 2018, stating that the plugging of the rotameter and the chemical feed lines, was considered as a ma�Anction under 2D.0535(a)(2), and not a permit deviation. The last quarterly deviation report was received on 11 October 2018, which showed two instances of maffiinctions of the cross flow scrubber(CD ID No. C-8). The first was on 10 July 2018 when the ORP dropped below 300 mV for 49 minutes due to a hole in the chemical feed line. 77ris feed line was replaced. The second instance was from 30-31 July 2018 when the ORP dropped below 300 mV for 20 hours and 15 minutes due to a failure of an offsite power transmission line. The facility called the power company and the line was repaired. The final instance involved packed tower scrubber(CD ID No. C-4) lasting from 30-31 July 2018 when the ORP dropped below 300 mV for 20 hours and 15 minutes due to a same power line issue that affected C-8. K. GENERAL CONDITION"P"—COMPLIANCE CERTIFICATION—The Permittee shall submit a compliance certification annually no later than March 151 APPEARED IN COMPLIANCE—the facility's ACC was received on 10 January 2018, and appeared complete and accurate. L. GENERAL CONDITION"X"—COMPLIANCE CERTIFICATION—The Permittee shall submit an annual emission inventory for the previous year no later than June 30te. APPEARED IN COMPLIANCE—The facility's CY2017 AQEI was received on 22 May 2018, and appeared complete and accurate. VIII. INSIGNIFICANT ACTIVITIES: Emission Source I.D.
