The emissions inventory for this permit is due 07/02/2017 with the renewal application.* *Hi hest HAP Emitted (inpounds) Directions Perdue Farms operates a chicken processing plant located on Highway 308 West, Lewiston Woodville, Bertie County. Directions from the Washington Regional Office are as follows: • Take Highway 17 N to Windsor and go through the first stoplight(funeral home on the right). • At the second stoplight,turn left onto Highway 308 West. • Stay on Highway 308 to Lewiston Woodville. Cross over Highway 11. The plant is on the left just outside town. • Stop at the second entrance to the facility where the tractor trailers are entering(guard gate). Be prepared to show identification and to open the car trunk for inspection. • Drive straight back through the yard. The environmental office is a white building on the left,next to the wastewater treatment system. Safety Concerns • There are tractor trailers frequently coming and going from the facility, so be careful when driving on the facility grounds. The bird receiving area is very dangerous with the trucks and forklifts unloading bird cages. If it's necessary to walk through the receiving hanger,wear a reflective vest and stay close to the escort. Make eye contact with the drivers. • Hearing protection,reflective vest,hard hat,safety glasses and safety shoes are required. Permit History • 10265ROO was issued on 10/17/2012. Perdue Farms had a Title V permit for a chicken processing plant and a rendering plant(Facility ID 0800081,Permit No. 03085T28). Perdue sold the rendering plant to Valley Protein and retained the chicken processing plant. As a result, Title V Permit 03085T29 was issued to Valley Protein,and Perdue was issued a new Synthetic Minor permit and premise number. • RO1 was issued on 2/14/2013 for a name change to the facility. Process Description • There are three receiving lines with hoods over each loading area. Birds are unloaded in boxes from trucks. DOA birds are collected in a dumpster for disposal off-site(rendering). • The birds are loaded into the hanging system(3 hanging rooms). Perdue employees hang the chickens by their feet onto moving racks. The room air goes to three baghouses that remove feathers and particulate. • Chickens' necks are slit,and the chickens are bled out(blood is collected for use at the rendering plant). The feathers(propane-fired singers are used)and heads are then removed. • Organs and feet are removed in the evisceration process. The feet are a saleable product. The organs and the meat are thoroughly inspected. Rejects are sent to the rendering plant. • In evisceration, all water is treated with aparacetic acid to kill bacteria. The plant has previously used tri-sodium phosphate. They can also use chlorine dioxide and hydrogen bromine. • The meat is transferred to the chillers(ammonia system). A maximum of 87,163 lbs of ammonia can be stored on-site. Ammonia loss would most commonly occur through seal leaks. There is very little loss from a shutdown. Perdue purges ammonia back to the storage tank, and then seals the tank off during shutdown. • Inspectors grade the meat. The meat is cut into parts,marinated,packaged,and shipped. • The plant generates about one truck of rendering material per hour. Permitted Sources/Inspection Observations I performed records review and physical inspection of the sources and controls on March 17,2015. The inspection was completed with assistance from Mr.Joey Baggett, Mr.Tim Mizelle and Ms. Ashton Weller. Calendar year 2014 and January-February 2015 records were reviewed. The following table contains a summary of all permitted emission sources and associated air pollution control devices. Some observations from the inspection are noted in bold print. __.__......_ __._..__........ _�. __........ __.__ _____._.._.....__ Emission Emission Source Control Control System Source ID Description System ID Description j v ES-1 jThree(3)live poultry receiving and handling CD-1 bagfilters(2,800 square feet of filter ES-2 systems CD-2 area,each)These units run at about ES-3 CD-3 18,000 ACFM each.

ES-22A Two(2)diesel-fired emergency/peak shaving ES-22B generators(2628 horsepower engine output) N/A N/A 1 (NESHA.P) The engines were not operating during the I :inspection. They are for emergency use only. No#6 fuel oil was combusted in 2014. Natural gas usage for 2014 was 153,940 mcf. 21,440 mcf has been combusted since January this year. Some fuel oil has been combusted since January 2015 (24,712 gallons). The shipping manifests for the fuel oil cite a sulfur content of 0.47%. Natural gas usage is metered. Fuel oil shipments are tracked by Perdue's accounting department in Salisbury. Billing statements are kept on file. Perdue wishes to begin burning No. 2 fuel oil as a backup to natural gas. We discussed that a permit modification may not be needed to begin usage since they are already permitted for No. 6 fuel oil. Joey will be mailing a request letter in the next week. The maximum pressure for each boiler is 150 psi. The boilers were constructed in 1975. Perdue has computerized panels that provide instantaneous operational data for the boilers. Parameter Boiler ES-4 Boiler ES-5 Steam pressure 109.1 109.7 Visible emissions 0% 0% Fuel No. 6 Oil Natural Gas Steam 13,8261bs/hr 6,3001bs/hr Stack temp 3630F 381OF Oxygen 5.5% 4.3% 95,066,392 chickens went through the processing facility in 2014(compared to 87,728,898 in 2012 and 96,650,292 chickens in 2011). The live poultry receiving and handling systems(ES-1,ES-2 and ES-3)are equipped with bagfilters to control particulate emissions(mostly from feathers). They were operating during the inspection. The bagfilters appeared to be in good physical condition. Pressure drop on each bagfilter was no more than 3 inches. These bagfilters have a stainless steel filter system that provides additional air exchanges in the hanging room and coverage over a larger building area. The collection barrels are emptied nightly. The following list of insignificant sources is attached to the permit: Source Exemption Regulation IES-6-refrigeration system 12Q.0102(c)(2)(E)(i) IES-7-propane-fired singers for poultry feathers(4.4 2Q.0102(c)(2)(E)(i) million Btu per hour maximum heat input) (g:\AQ\Shared\Bertie08\00109\20150317al6.doc) Page 3 It is my understanding that no pnysical or operational changes made to thc insignificant sources. I did not physically inspect the insignificant sources. All of the emissions from the singers come solely from propane combustion. 59,340 gallons of propane were combusted in 2014(58,963 gallons in 2013). The only regulation that applies to the refrigeration system is 112R(discussed in the Regulatory Review below). A maximum of 87,163 lbs of ammonia is stored on-site. Perdue figures the loss of ammonia based on what they have to replace. 13,022 lbs were purchased/emitted in 2014(compared to 12,119 lbs of ammonia purchased/emitted in 2013 and 24,523 lbs in 2012). Applicable Reeulations/Reaulatory Review 2D.0202 "Registration of Air Pollution Sources" The Director has the authority to require the registration of air pollution sources, and require them to submit information about the source. It is under this Rule that the Division is requiring facilities to submit an emissions inventory 90 days before a Permit expires. Perdue submitted an annual TV inventory on 6/26/2013 because it held a Title V permit up until October 2012. The processing plant emissions are for all of 2012,but the rendering emissions were covered under Perdue until October 17, 2012. The inventory emissions were combined with emissions calculated by Valley Protein for October 17-December 31, 2012 in IBEAM for facility ID 0800081. The next inventory will be due with the permit renewal application due in July 2017. 2D.0503 "Particulates from Fuel Burning Indirect Heat Exchangers" The boilers have never been tested for particulate. ES-4 and ES-5 each have an emission limit of0.42 lb/MM Btu. Worst case emissions are from fuel oil combustion. Total estimated emissions using AP-42 (boilers<100 MMBtu/hr,worst case assuming all No.6 oil use): 40,600,000 Btu/hr(gallon/151,000 Btu)(10 lb/1000 gallons)=2.7 lbs/hr emitted 2.7 lbs/hr(hr/40.6 MMBtu)=0.066 lb/MMBtu The combined fuel oil emissions of all boilers(sans the temporary boilers)are less than the limit for a single boiler. The AP-42 particulate factor for natural gas is 0.007 lb/MMBtu. Perdue is assumed in compliance with 2D.0503. 2D.0515 "Particulates from Miscellaneous Industrial Processes" This rule applies to the three poultry receiving and handling systems. Assuming each bird weighs a minimum of one pound,allowable emissions are: P<30 tons/hr E=4.10 x 200.67 E=32.42 lbs/hr For the receiving baghouses, Perdue bases emissions on a factor of 0.0003 lbs per bird processed. The factor is based upon the weight of the amount of particulate(feathers and dust)collected over one day of processing divided by a total of 16 hours of production per day. 40,000 maximum lbs birds/hr x 0.0003 lbs/bird processed x(1-.999)percent control eff. =0.012 lbs/hr The facility should comply with the rule as long as the baghouses are maintained. They perform weekly maintenance external inspections and quarterly internal inspections of the baghouses. I reviewed all the records for 2014 to current. The quarterly 2014/2015 inspection dates are 3/22/2014, 5/17/2014, 8/16/2014, 11/15/2014,and 3/14/2015. And example of the quarterly inspections is attached to the file copy of this report. (g:\AQ\Shared\Bertie08\00109\20150317al6.doc) Page 4 213.0515 also applies to the si„rk.,s.The only emission from the singers is .._i propane gas combustion. 0.008 lb/MMBtu(40.6 MMBtu/hr)=0.32 lb/hr Perdue appears to be in compliance with 2D.0515. 2D.0516 "Sulfur Dioxide Emissions from Combustion Sources" The regulation applies to the No. 6 fuel oil and natural gas combustion on the boilers,and the diesel generator. Compliance is assumed since their February shipment fuel certification indicates a sulfur content of 0.47%by weight. Natural gas and propane contain negligible sulfur. Perdue is in compliance with 2D.0516. 2D.0521 "Control of Visible Emissions" This rule applies to all sources.No visible emissions violation has historically been recorded for this facility. All of the sources' visible emissions were observed to be 0%during the inspection. Perdue is assumed in compliance with 2D.0521. 2D.0535 "Excess Emissions Reporting and Malfunctions" Perdue is required to report excess emissions from deviations or malfunctions that last more than four hours. None were reported since the last inspection. 2D.0540 "Particulates from Fugitive Non process Dust Emission Sources" The facility may not generate fugitive dusts that go beyond the property boundary and cause a substantive complaint. Fugitive emissions are those that don't pass through a stack or vent,and are generated within plant property boundaries. The primary fugitives from Perdue come from truck traffic. I did not see any fugitive dust leave the property boundary during the inspection. I did observe dust on-site generated by chicken truck traffic. 2D.1806 "Control and Prohibition of Odorous Emissions" Odor is generated by the chicken processing facility primarily at the wastewater treatment system. There are treatment ponds located between the processing plant and Valley Protein's rendering plant. Both facilities use the wastewater system,but Perdue is owns and operates it. The rendering plant generates a musty, slightly bitter"cooked"(my opinion)smell from the process emission sources. The wastewater treatment system odor is also musty, but has a rotten tinge. Wastewater odors seem more likely to leave the property in warmer months while operating the aerators. Perdue staff is supposed to pay attention to wind direction before running the aerators on really hot days. There are residences on the other side of the tree line to the north that can be affected by wastewater odors. I did notice odors on and off-site during the inspection. As I approached the plant from the south on Highway 308 about 10:00 am, I smelled cooked odor at the church, which is less than a tenth of mile from the plant. The odor continued along the highway until just after passing the plant. The cooked odor was very strong at approximately 12:00 pm when we physically inspected Perdue's emergency generators,which are near the anaerobic pond and close to the rendering plant. At that time I noted there was a steady wind from the west and the temperature was 71°F(see the weatherunderground.com data attached to the file copy of this report). There was an odor in the receiving yard similar to a chicken house odor during the inspection. There were many loaded trucks(live chickens)waiting in the yard under open hangers with fans blowing on the chickens. The large aerators and the tube aerators in the equalization basin were in operation during the inspection. The wastewater system did not generate odor for most of the inspection,but I did smell it around 12:33 pm when I completed the inspection. I was standing right next to the aeration pond, and it did not appear to carry far from the pond. I performed odor surveillance along Highway 308 from Lewiston to Kelford from 12:40- 12:50 pm. The same cooked odor was detected at the nearby church(which is east of the facilities). There are two openings to the stormwater drain located along the left edge of the loading yard and about 50 feet from the wastewater pond. Wash water from trucks go to the second drain, and some of the water can stagnate in the drain. The odor can be very strong, but I did not smell it during this inspection. I smelled it (g:\AQ\Shared\Bertie08\00109\201503]7a l 6.doc) Page 5 J during last year's inspection, nut the odor did not carry further than 20-36 feet from the drain openings. Joey noted again that he has never smelled it off-site. I believe a decent wind could mix this odor with the wastewater and rendering odors. I performed another odor surveillance from Highway 308,and along the plant road on 3/19/2015,while conducting an annual inspection at W.E.Partners 11. I did not observe any odor from Perdue. The legislature has passed rules that require agricultural related complaints and enforcement be kept confidential. Agricultural operations have not yet been defined under the legislation, so for now the chicken processing facility is to be considered an agricultural operation. Therefore,any documentation of complaints received by DAQ concerning Perdue must be stored in the WaRO confidential cabinet. 2Q.031 S "Synthetic Minor Facilities" To avoid Title V permitting, Perdue limited criteria pollutant emissions to less than 100 tpy each(SOZ and NOx are the limiting pollutants). The facility is inherently small for HAP emissions. Permit Specific Condition No. 12 requires Perdue to track monthly fuel usage and calculate monthly emissions of SOZ and NOx. I reviewed their fuel usage records,and they were complete. Perdue is required to submit an annual report of fuel usage and rolling 12-month emissions of SOZ and NOx over the calendar year. The reports have been on time,complete and in compliance. 2Q.0317 "Avoidance Conditions"(of Prevention of Signification Deterioration) To avoid PSD permitting, Specific Condition No. 13. requires Perdue to meet the recordkeeping and reporting requirements Permit Condition No. 12. For 2Q.0315. 112R Risk Management Plans 112R applies for ammonia use in Perdue's refrigeration system at the processing facility. DAQ I I2R inspections are on a 4-5 cycle. The most recent inspection was conducted by Alicia Mangum and me on 3/30/2012. All of the elements listed on our inspection form appeared to be met by Perdue. The elements of 112r are incorporated into the facility's overall PSM library. The results of the 112R inspection were recorded on separate forms that are kept in a logbook for all 112R inspections done by WARO(Robert Bright keeps the book). A copy of the forms was sent to Mike Reid at DAQ Central Office. There have been no significant changes to their PSM program since the last 112R inspection. No new equipment has been installed. When Perdue sold the rendering plant to Valley, it received a new permit and premise number for the chicken processing plant. It gives the appearance that facility 0800109 has never had a112R inspection because all of the records are associated with Valley's facility ID 0800081. To remedy the confusion,WaRO has entered a full I I2R inspection in the Actions Inspections IBEAM database in association with this inspection. This is only a placeholder representing the 3/30/2012 112R inspection. Subpart JJJJJJ-NESHAP for Boiler Area Sources This facility is a minor source of HAPs,but the Area Source Boiler GACT applies to their boilers. The boilers are all greater than 10 MMBtu/hr and burn fuel oil only during natural gas curtailment. The boilers are considered existing sources under the regulation. Because they only burn oil during curtailment,the boilers can be exempted from the regulation as natural gas boilers. However,Perdue wishes to retain the opportunity to switch to oil outside of curtailment. Perdue submitted the initial notification for the boilers on 9/20/2011. The boilers must be tuned every two years. The following must be performed to meet the tune-up requirement: (g:\AQ\Shared\Bertie08\00 109\20150317al 6.doc) Page 6 • As applicable, inspect the uu,ner,and clean or replace any component.—the burner as necessary(the Permittee may delay the burner inspection until the next scheduled unit shutdown,but must inspect each burner at least once every 36 months). • Inspect the flame pattern,as applicable,and adjust the burner as necessary to optimize the flame pattern. The adjustment should be consistent with the manufacturer's specifications, if available. • Inspect the system controlling the air-to-fuel ratio, as applicable, and ensure that it is correctly calibrated and functioning properly. • Optimize total emissions of carbon monoxide.This optimization should be consistent with the manufacturer's specifications, if available. • Measure the concentrations in the effluent stream of carbon monoxide in parts per million, by volume, and oxygen in volume percent,before and after the adjustments are made(measurements may be either on a dry or wet basis, as long as it is the same basis before and after the adjustments are made). • Maintain onsite a biennial report(see item c. below)containing the concentrations of CO in the effluent stream in parts per million,by volume, and oxygen in volume percent, a description of any corrective actions taken,and the type and amount of fuel used over the 12 months prior to the biennial tune-up. Perdue's official initial tune-ups on the boilers were conducted on 1/26/2014(the reports are in the WaRO file). However,C&C performs monthly tune-ups on the boilers. I have looked at their records, and the monthly tune-ups may meet the requirements under the GACT. The latest ones were conducted on 2/18/2015 and 1/7/2015. Perdue has also completed energy assessments for the boilers. A copy of the energy assessment results is in the DAQ file. Perdue submitted the Notice of Compliance Status report required by Subpart 6J to EPA CDX/CEDRI and DAQ on 5/08/2014. ES-4 and ES-5 have daily,weekly and monthly PM routes.There have been no boiler malfunctions since last inspection. When there is a malfunction,a work order is generated out of the Maximo maintenance system. Subpart ZZZZ-NESIIAP for Stationary Reciprocating Internal Combustion Engines The engines are considered existing because they were installed prior to June 12, 2006. Perdue submitted the initial notification for the two diesel generators(2628 hp each)on 1/25/2012.They were previously categorized as peak shaving,and were granted a compliance extension to May 3,2014. However,Perdue made a decision to operate these engines only for emergencies. The engines are listed as emergency/peak shaving on the permit,and permit con3i-f:i n_To._A:I—. 4--s�o peak shavers, so changes need to be made in the next permit modification or renewal. — - - We read the hour meters on each engine. Engine 22A read at 996 cumulative hours, and 22B read at 782 cumulative hours. Perdue has recorded the hours operated each time they start up the engines. Neither engine was operated more than 8 hours in 2014 for maintenance and readiness testing. There were no hours in 2014 where the engines were operated for emergency purposes. Maintenance and Work Practices • Change oil and filter every 500 hours of operation or annually,whichever comes first. • Inspect air cleaner every 1,000 hours of operation or annually,whichever comes first, and replace as necessary. (g:\AQ\Shared\Bertie08\00109\20150317al6.doc) Page 7 • Inspect all hoses and belts every 500 hours of operation or annually, wntchever comes first, and replace as necessary. • Operate and maintain the engine and control device(if there is one)according to the manufacturer's emission related written instructions or your employer's plan that minimizes emissions from the engine to the extent practicable. • Install a non-resettable hour meter. • Minimize the engine's time spent at idle during startup and minimize the engine's startup time to a period needed for appropriate and safe loading of the engine,not to exceed 30 minutes. Enaine Operation There is no time limit on use in emergency situations. Each emergency engine may be operated up to 100 hours per year for maintenance checks and readiness testing, provided that the tests are recommended by federal, state or local government, the manufacturer, the vendor, the regional transmission authority or equivalent balancing authority and transmission operator, or the insurance company associated with the engine. Recordkeeping—Keep the following records for at least five(5)years showing: • the engine was operated and maintained according to the manufacturer's emission related operation and maintenance instructions or the Permittee's maintenance plan which must provide for the maintenance and operation of the engine in a manner consistent with good air pollution control practice for minimizing emissions. This includes keeping records of maintenance requirements listed above(oil and filter changes,air cleaner and hose inspections). During 2014 one of the engines was shipped out for refurbishment from February to June. They plan to send the other engine for refurbishment this year. Maintenance/testing is done monthly by Perdue. The Maximo system was down during the inspection, so we could not access the records for maintenance. We did look through some paper records for several months instead. The most recent readiness test and maintenance inspection were on 3/10/2015. One of the engines met the maintenance and work practice requirements above when it went back to the manufacturer for refurbishment. The other engine only appeared to have specific record of hose and belt replacement/repair. However, Gregory Poole had been onsite to conduct maintenance on 4/23/2014, 7/16/2014, and 8/07/2014. Their maintenance manager agreed to keep a more specific record of when oil/filter was changed, and when the air cleaner and hoses/belts are inspected. • the hours of operation of the engine that is recorded through the non-resettable hour meter. Document how many hours are spent for emergency operation vs.hours for maintenance and testing(date, start time and end time of the engine operation for these purposes). I looked through the operator's logs of hours they recorded from the engine meters. The records were complete Monitoring,Recordkeeping and Reporting(MRR) All permit-required records were reviewed for calendar year 2014 to February 2015. There was a minor issue with fully documenting completion of Subpart ZZZZ maintenance and work practice records. However, the records did not appear to be a compliance issue. Perdue's reports have been submitted on time and are complete. The MRR requirements are listed in the table below.

Enforcement History Perdue sold the rendering plant to Valley Proteins in October 2012. A new premise and permit number were assigned to Perdue. A new compliance history is established with the new permit. No NOD or NOV has been issued to the facility. Comments/Conclusions Perdue appeared to be in compliance with the permit conditions at the time of the inspection. (g:\AQ\Shared\Bertie08\00109\201503]7al6.doc) Page 9
