The facility has completed the required energy assessments,and is conducting boiler tune-ups semiannually with the last tune-up being performed on 06 October 2015. II. 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. III. 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. One is permitted as an emergency boiler. 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 room air control. This facility employs 130 workers 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. V. INSPECTION SUMMARY: On 02 December 2015 I,Joshua Harris,arrived at Valley Protein to conduct an air quality compliance inspection_ I noted no odors as I drove past the plant and wastewater lagoons. While on-site,there were light rendering odors close to the buildings,but it seemed to dissipate after —50 feet. I met with Chris Bivens,General Manager,and James Hodges,Environmental Manager. Mr." Hodges immediately mentioned that the facility experienced a loss of power to one of its breaker panels which powers the ORP monitoring and chemical injection system for the crossflow scrubber(fD No.C8). He stated that the failure occurred around 7 PM the previous day,and that the facility recovered from the power failure in the hours prior to my arrival. Approximately 12 hours of ORP data was lost for C8. Mr.Hodgesi stated that he would be drafting a deviation report to submit to FRO. There was a brief discussion about the changes to the material storage rules within 2D .0539,and, after the inspection,I emailed Mr. Hodges a copy of the language that is currently being used for permitting. Mr. Hodges reviewed the FacFinder data,noted i no changes,then we began reviewing the facility's records. Records at the plant are well-kept,and are readily available. The plant largely burned only NG in 2015,with some instances of combusting saleable fat, totaling 1,105 gallons through November 2015. The facility;has not accepted any fuel oil in years,and there was none on-site at the time of the inspection. During the last compliance inspection it was noted that one operator was improperly logging boilers as being used as control devices when they are in low-fire. The facility has changed its logs in an attempt to correct this issue,but the operator is still inconsistent with logging practices. Mr. Hodges explained that it is physically impossible for the boiler to operate while in low-fire(pin position one). There is an interlock which keeps a damper closed, preventing vapors from being admitted to the boiler,when the pin is in position one. Once the operator places the boiler in mid-fire(position two),a solenoid valve admits air to the damper, and it is pneumatically opened. After reviewing the facility's records, Mr. Hodges and I toured the facility. i v i We first stopped by the wastewater lagoon,where there was no detectible odor. The facility's boilers were running on NG,with zero opacity. All gauge readings(flow rate/pressure,ORP)were operational and within the permit limits. At the time of the inspection,the longest duration that any material had been waiting t on site was 6.5 hours. VI, PERMITTED EMISSION SOURCES: emission Control i Source.

The inlets to crossflow scrubber C-8(13 psig rrrinimurn) were operating at 24 psig(Is'stage)and 28 psig(2"d stage). The ORP values were observed to be 366 rnV(packed tower scrubber C4) and 3201440 nrV (stages I and Hof cross flow scrubber C8). the condensers were last serviced on 29 March 2015. Vallee'Protein has received no odor complaints recently. The pressures are monitored and recorded each sh f; the ORPs are on continuous strip charts. All showed compliance. Mr. Hodges will be submitting a deviation report for the 12 hours of lost ORP data for C8 described in the inspection summary. Operator's log for checking high-fire status when the boilers an e used fon odor control appeared complete, and logs are taken during each shift. As previously stated, the facility has changed the way the logs are taken after the last inspection revealed minor issues. One operator was periodically taking logs using the old notation, but the logs still indicated compliance. The facility has a rigorous cleaning and inspection regimen, which exceeds the permit requirement and is completed weekly. Mr. Hodges attributes much of the facility's progress to this routine, and says he intends to continue with it. 2. 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.
